A pilot investigation of Farm Assurance assessors’ attitude to farm animal welfare as a confounding factor to training in pig welfare outcome measures
Authors: Mullan S , Edwards SA , Butterworth A , Whay HR , Main DCJ
Published: January 2023

The effect of Farm Assurance (FA) assessors’ attitude to farm animal welfare on the inter-observer reliability of some welfare outcome measures achieved following training was investigated as part of a larger project examining the feasibility and benefits of the incorporation of some on-farm welfare outcome assessments into UK Pig Farm Assurance Schemes. A total of thirty-one FA assessors were trained in three training sessions to assess the following welfare outcome measures: body lesions, tail lesions, severe tail lesions, lameness and pigs requiring hospitalisation. Assessment of photographs, live observations of individual pigs and pens of pigs were used to generate inter-observer reliability data. A previously validated farm animal welfare questionnaire was used to assess the FA assessors’ attitudes to farm animal welfare. Principal Component Analysis of FA assessor scores for this questionnaire resulted in two major components, with component 1 termed ‘pigs have mental welfare’ and component 2 termed ‘people-centric, pigs as profit’. FA assessors demonstrated a range in attitudes to farm animal welfare and, when assessing the same pigs, recorded a range in prevalence of welfare outcome measures and degree of agreement with a gold standard following training. There were only seven out of a possible 98 significant correlations between the FA assessor scores for components 1 and 2 and their recorded prevalence of welfare measures and levels of agreement with a gold standard. In particular, FA assessors’ scores for component 1 were significantly positively correlated with the recorded prevalence for pigs requiring hospitalisation in two of the three training sessions although there was no effect on the agreement with a gold standard for this measure. These results indicate that training in welfare outcomes, defined by a standard protocol, is relatively unconfounded by observer attitudes to farm animal welfare. To obtain better levels of agreement between assessors, and therefore more reliable data, it is recommended that FA schemes concentrate their resources on providing good quality training in a well-defined protocol and reliability testing and that they do not need to attempt to account for the attitudes of the FA assessors to farm animal welfare.
Is welfare all that matters? A discussion of what should be included in policy-making regarding animals
Authors: Yeates JW , Röcklinsberg H , Gjerris M
Published: January 2023

Policy-making concerned with animals often includes human interests, such as economy, trade, environmental protection, disease control, species conservation etc. When it comes to the interests of the animals, such policy-making often makes use of the results of animal welfare science to provide assessments of ethically relevant concerns for animals. This has provided a scientific rigour that has helped to overcome controversies and allowed debates to move forward according to generally agreed methodologies. However, this focus can lead to policies leaving out other important issues relevant to animals. This can be considered as a problem of what is included in welfare science, or of what is included in policy. This suggests two possible solutions: expanding animal welfare science to address all ethical concerns about animals’ interests or widening the perspective considered in policymaking to encompass other important ethical concerns about animals than welfare. The latter appears the better option. This requires both a ‘philosophy of animal welfare science’, a ‘philosophy of decision-making about animals’, and greater transparency about what is included or excluded from both animal welfare science and the politics of animal policy.
Development and testing of a novel instrument to measure health-related quality of life (HRQL) of farmed pigs and promote welfare enhancement (Part 2)
Authors: Wiseman-Orr ML , Scott EM , Nolan AM
Published: January 2023

The development of a novel structured questionnaire instrument to measure health-related quality of life (HRQL) in individual farmed pigs was described previously (companion paper). The instrument embraces the measurement of positive welfare, and was developed with farmers and stockpersons, for use by them on-farm. This paper describes the development of a scoring methodology for the instrument and provides evidence for its construct validity. Field testing on four commercial farm units indicated that scores for health and affect correctly allocated 88.7% of pigs to known treatment groups and strongly predicted previously defined intervention levels. The tool was also used in an experimental study alongside other measures to identify the impact of early-life challenges (mixing of pregnant gilts and tail-docking neonatal pigs) on subsequent pig welfare, and identified long-term changes in HRQL of prenatally stressed piglets, a finding supported by other measures. This work describes a novel approach to farm-level welfare assessment in which entirely animal-based HRQL measurement can provide a measure of welfare at the herd level while retaining information about individuals within the herd and about aspects of provision that can be targets of intervention to improve welfare, and promotes a move from welfare assurance to welfare enhancement.
The effect of environmental enrichment and visitors on the behaviour and welfare of two captive hamadryas baboons (Papio hamadryas)
Authors: Bortolini TS , Bicca-Marques JC
Published: January 2023

The welfare of zoo animals depends on a combination of physical, social, dietary and other ecological characteristics of the captive setting. We analysed the influence of the transfer of an adult couple of hamadryas baboons (Papio hamadryas) from a small and non-enriched cage that was closed to the public to a larger and enriched exhibit at the visitation area of the Sapucaia do Sul Zoological Park, RS, Brazil. A total of 350 h divided into four stages were spent observing the baboons: (i) in the non-enriched enclosure before the transfer; (ii) soon after the transfer to the enriched enclosure; (iii) six months; and (iv) 12 months after the transfer. The occurrence of stereotypic, social aggressive and social affiliative behaviours was recorded by ‘all occurrences’ sampling. The female showed a decrease in frequency of a stereotypic behaviour (spinning) and an increase in grooming in the enriched enclosure. The male showed a decrease in the frequency of certain stress-related or stereotypic behaviours after transfer, but other stress-related behaviours either increased or remained constant. The male behaviour of throwing faeces was affected by the presence of visitors. We suggest that the well-being of the female was more positively influenced by the new enclosure than that of the male, although gender differences may reflect the normal behavioural repertoire of this sexually dimorphic species.
Four types of activities that affect animals: implications for animal welfare science and animal ethics philosophy
Authors: Fraser D , MacRae AM
Published: January 2023

People affect animals through four broad types of activity: (1) people keep companion, farm, laboratory and captive wild animals, often while using them for some purpose; (2) people cause deliberate harm to animals through activities such as slaughter, pest control, hunting, and toxicology testing; (3) people cause direct but unintended harm to animals through crop production, transportation, night-time lighting, and many other human activities; and (4) people harm animals indirectly by disturbing ecological systems and the processes of nature, for example by destroying habitat, introducing foreign species, and causing pollution and climate change. Each type of activity affects vast numbers of animals and raises different scientific and ethical challenges. In Type 1 activities (keeping animals), the challenge is to improve care, sometimes by finding options that benefit both people and animals. In Type 2 activities (deliberate harm), the challenge is to avoid compounding intentional harms with additional, unintended harms, such as animal suffering. For Type 3 and 4 activities, the challenges are to understand the unintended and indirect harms that people cause, to motivate people to recognise and avoid such harms, and to find less harmful ways of achieving human goals. With Type 4 activities, this may involve recognising commonalities between animal welfare, conservation and human well-being. Animal welfare science and animal ethics philosophy have traditionally focused on Type 1 and 2 activities. These fields need to include Type 3 and 4 activities, especially as they increase with human population growth.
Comparison of pig behaviour when given a sequence of enrichment objects or a chain continuously
Authors: Van de Perre V , Driessen B , Van Thielen J , Verbeke G , Geers R
Published: January 2023

Tail biting is a major problem in modern pig(Sus scrofa)production and results in a reduction of animal welfare and productive performance. Biting behaviour has been shown to be decreased by the use of enrichment objects. In this study, 108 pigs housed in a room with 12 pens were observed and a sequence of seven different enrichment materials was tested. Gilts and barrows were housed together and received a new enrichment object each week starting from three different points in the fattening period, ie 20, 40 or 70 kg bodyweight. Toy-contact and biting-penmate behaviour were observed during one hour at day of introduction and five days later. A continuous sequence of seven enrichment objects reduced biting-penmate behaviour and the number of wounds compared to providing only a single toy (chain). This study also confirmed that not every object was feasible as an enrichment object for growing pigs. Generally, the highest toy contact was observed together with the highest biting-penmate behaviour. Most toy-contact and biting-penmate behaviour was observed between 20 and 40 kg bodyweight and was decreasing over age. Providing a sequence of toys for the first time induced toy-contact behaviour while reducing bitingpenmate behaviour but decreased after applying the same sequence for the second or third time. The presence of a single chain or a sequence of different toys had no effect on growth and feed conversion. The ideal sequence should maintain toy-contact behaviour without competition in order to avoid biting-penmate behaviour and reduced animal welfare.
Review of the evidence of sentience in cephalopod molluscs and decapod crustaceans
Authors: Wickens S
Published: January 2023

All cephalopod molluscs and decapod crustaceans should be regarded as sentient and protected under UK animal welfare law. This is the headline conclusion of this thoughtful report, that is going to have a profound impact on the way these animals are treated within the UK — and likely inform policy elsewhere. In response, the UK government has indicated that they accept this position and will look to/have extended forthcoming animal welfare legislation to include lobsters, octopus and crabs and all other decapod crustaceans and cephalopod molluscs.
System architecture for a compact high range resolution frequency comb OFDM radar
Authors: Quint Alexander , Nuss Benjamin , Diewald Axel , Zwick Thomas
Published: January 2023

With increasing demands on resolution and flexibility in current and future radar applications, the focus is moving to digital radar systems such as orthogonal frequency-division multiplexing (OFDM) radars. To achieve high bandwidths and consequently a high range resolution, high sampling rates are needed. To overcome this constraint, an approach called frequency comb OFDM radar has been developed. This paper presents a novel, hardware efficient implementation of such a frequency comb OFDM radar including a novel way of comb generation. Special attention is put on the suppression of unwanted frequency components. Measurements which demonstrate the functionality of the hardware efficient radar system in combination with the frequency comb OFDM technique are presented.
Design and analysis of a compact microstrip lowpass–bandpass diplexer with good performance for wireless applications
Authors: Rezaei Abbas , Yahya Salah I. , Nouri Leila
Published: January 2023

This paper presents the design of a novel lowpass–bandpass diplexer with compact size and good performance using microstrip cells. For this purpose, two microstrip lowpass and bandpass filters are separately designed and mathematically analyzed. The proposed microstrip diplexer has a novel and simple structure. It occupies a compact area of 0.037 λg2 (722 mm2), and its insertion loss and S11 at both channels are low. The insertion loss at the lower and upper channels is only 0.047 and 0.16 dB, respectively. Meanwhile, both channels are flat with the maximum group delay of 1.68 ns which is the lowest compared to the previously reported diplexers mentioned in this paper. To design the proposed diplexer, first, a lowpass diplexer with good performance is designed which has low losses and a good figure of merit. It has a flat passband with a sharp roll-off. Then, to achieve the proposed diplexer, a bandpass resonator is added to the lowpass filter without any extra matching circuit, which saves the overall size. The proposed diplexer is designed, simulated, and fabricated, where the simulation and measurement results are close.
Dissecting the risky-choice framing effect: Numeracy as an individual-difference factor in weighting risky and riskless options
Authors: Peters Ellen , Levin Irwin P.
Published: January 2023

Using five variants of the Asian Disease Problem, we dissected the risky-choice framing effect by requiring each participant to provide preference ratings for the full decision problem and also to provide attractiveness ratings for each of the component parts, i.e., the sure-thing option and the risky option. Consistent with previous research, more risky choices were made by respondents receiving negatively framed versions of the decision problems than by those receiving positively framed versions. However, different processes were evident for those scoring high and low on numeracy. Whereas the choices of the less numerate showed a large effect of frame above and beyond any influence of their evaluations of the separate options, the choices of the highly numerate were almost completely accounted for by their attractiveness ratings of the separate options. These results are consistent with an increased tendency of the highly numerate to integrate complex numeric information in the construction of their preferences and a tendency for the less numerate to respond more superficially to non-numeric sources of information.
An alternative approach for eliciting willingness-to-pay: A randomized Internet trial
Authors: Damschroder Laura J. , Ubel Peter A. , Riis Jason , Smith Dylan M.
Published: January 2023

Open-ended methods that elicit willingness-to-pay (WTP) in terms of absolute dollars often result in high rates of questionable and highly skewed responses, insensitivity to changes in health state, and raise an ethical issue related to its association with personal income. We conducted a 2x2 randomized trial over the Internet to test 4 WTP formats: 1) WTP in dollars; 2) WTP as a percentage of financial resources; 3) WTP in terms of monthly payments; and 4) WTP as a single lump-sum amount. WTP as a percentage of financial resources generated fewer questionable values, had better distribution properties, greater sensitivity to severity of health states, and was not associated with income. WTP elicited on a monthly basis also showed promise.
The effects of losses and event splitting on the Allais paradox
Authors: Weber Bethany J.
Published: January 2023

The Allais Paradox, or common consequence effect, has been a standard challenge to normative theories of risky choice since its proposal over 60 years ago. However, neither its causes nor the conditions necessary to create the effect are well understood. Two experiments test the effects of losses and event splitting on the Allais Paradox. Experiment 1 found that the Allais Paradox occurs for both gain and mixed gambles and is reflected for loss gambles produced by reflection across the origin. Experiment 2 found that the Allais Paradox is eliminated by splitting the outcomes even when the probabilities used do not increase the salience of the common consequence. The results of Experiment 1 are consistent with Cumulative Prospect Theory, the current leading theory of risky choice. However, the results of Experiment 2 are problematic for Cumulative Prospect Theory and suggest that alternate explanations for the Allais Paradox must be sought.
Direct and indirect effects of pathological gambling on risk attitudes
Authors: Brañas-Garza Pablo , Georgantzís Nikolaos , Guillen Pablo
Published: January 2023

We study individual decision making in a lottery-choice task performed by three different populations: gamblers under psychological treatment (“addicts”), gamblers’ spouses (“victims”), and people who are neither gamblers or gamblers’ spouses (“normals”). We find that addicts are willing to take less risk than normals, but the difference is smaller as a gambler’s time under treatment increases. The large majority of victims report themselves unwilling to take any risk at all. However, addicts in the first year of treatment react more than other addicts to the different values of the risk-return parameter.
In the winning mood: Affect in the Iowa gambling task
Authors: de Vries Marieke , Holland Rob W. , Witteman Cilia L. M.
Published: January 2023

The present research aimed to test the role of mood in the Iowa Gambling Task (IGT; Bechara et al., 1994). In the IGT, participants can win or lose money by picking cards from four different decks. They have to learn by experience that two decks are overall advantageous and two decks are overall disadvantageous. Previous studies have shown that at an early stage in this card-game, players begin to display a tendency towards the advantageous decks. Subsequent research suggested that at this stage, people base their decisions on conscious gut feelings (Wagar & Dixon, 2006). Based on empirical evidence for the relation between mood and cognitive processing-styles, we expected and consistently found that, compared to a negative mood state, reported and induced positive mood states increased this early tendency towards advantageous decks. Our results provide support for the idea that a positive mood causes stronger reliance on affective signals in decision-making than a negative mood.
Actor/observer asymmetry in risky decision making
Authors: Fernandez-Duque Diego , Wifall Timothy
Published: January 2023

Are people willing to gamble more for themselves than what they deem reasonable for others? We addressed this question in a simplified computer gambling task in which subjects chose from a set of 10 cards. Subjects selected one card at a time after being instructed that 9 cards were good (win a dollar per card) and one was really bad (lose all the money and end the game). Subjects could stop playing at any time to collect their winnings. Some subjects played the game, others observed a confederate. Both groups took risks beyond what was rational (i.e., 5 cards) but actors were riskier than observers. The actor/observer asymmetry occurred even after controlling for monetary outcome (i.e., having observers win prizes) and after controlling for how the question was framed (i.e., asking observers what they themselves would do as opposed to what the confederate should do). We discuss these results in relation to theories of decision making that emphasize separate contributions of rational and experiential systems.
Biases in casino betting: The hot hand and the gambler’s fallacy
Authors: Sundali James , Croson Rachel
Published: January 2023

We examine two departures of individual perceptions of randomness from probability theory: the hot hand and the gambler's fallacy, and their respective opposites. This paper's first contribution is to use data from the field (individuals playing roulette in a casino) to demonstrate the existence and impact of these biases that have been previously documented in the lab. Decisions in the field are consistent with biased beliefs, although we observe significant individual heterogeneity in the population. A second contribution is to separately identify these biases within a given individual, then to examine their within-person correlation. We find a positive and significant correlation across individuals between hot hand and gambler's fallacy biases, suggesting a common (root) cause of the two related errors. We speculate as to the source of this correlation (locus of control), and suggest future research which could test this speculation.
A psychological law of inertia and the illusion of loss aversion
Authors: Gal David
Published: January 2023

The principle of loss aversion is thought to explain a wide range of anomalous phenomena involving tradeoffs between losses and gains. In this article, I show that the anomalies loss aversion was introduced to explain - the risky bet premium, the endowment effect, and the status-quo bias - are characterized not only by a loss/gain tradeoff, but by a tradeoff between the status-quo and change; and, that a propensity towards the status-quo in the latter tradeoff is sufficient to explain these phenomena. Moreover, I show that two basic psychological principles - (1) that motives drive behavior; and (2) that preferences tend to be fuzzy and ill-defined - imply the existence of a robust and fundamental propensity of this sort. Thus, a loss aversion principle is rendered superfluous to an account of the phenomena it was introduced to explain.
Gender Differences in Risk Assessment: Why do Women Take Fewer Risks than Men?
Authors: Harris Christine R. , Jenkins Michael
Published: January 2023

Across many real-world domains, men engage in more risky behaviors than do women. To examine some of the beliefs and preferences that underlie this difference, 657 participants assessed their likelihood of engaging in various risky activities relating to four different domains (gambling, health, recreation, and social), and reported their perceptions of (1) probability of negative outcomes, (2) severity of potential negative outcomes, and (3) enjoyment expected from the risky activities. Women’s greater perceived likelihood of negative outcomes and lesser expectation of enjoyment partially mediated their lower propensity toward risky choices in gambling, recreation, and health domains. Perceptions of severity of potential outcomes was a partial mediator in the gambling and health domains. The genders did not differ in their propensity towards taking social risks. A fifth domain of activities associated with high potential payoffs and fixed minor costs was also assessed. In contrast to other domains, women reported being more likely to engage in behaviors in this domain. This gender difference was partially mediated by women’s more optimistic judgments of the probability of good outcomes and of outcomes being more intensely positive.
The effects of behavioral and outcome feedback on prudent decision-making under conditions of present and future uncertainty
Authors: Brown Jay C.
Published: January 2023

One of the largest reasons decision-makers make bad decisions (act imprudently) is that the world is full of uncertainty, we feel uncertain about the consequences of our actions. Participants played a repeated game in which decisions were made under various types of uncertainty (either no uncertainty, uncertainty about the present consequences of behaviors, uncertainty about the future consequences of behavior, or both types of uncertainty). The game required prudent decision making for success. While playing the game one of three types of feedback was placed between trials, either no feedback, behavioral feedback, or behavioral plus outcome feedback. Prudent decision-making decreased when both types of uncertainty were added. Further, the addition of feedback increased prudent decision-making when future uncertainty was present. The increase in prudent decisions appears to be from feedback’s ability to allow us to create probabilities associated with behaviors and their consequences, implying that anything that reduces the uncertainty people feel in a world full of uncertainty will increase their ability to make prudent decisions.
A short form of the Maximization Scale: Factor structure, reliability and validity studies
Authors: Nenkov Gergana Y. , Morrin Maureen , Ward Andrew , Schwartz Barry , Hulland John
Published: January 2023

We conducted an analysis of the 13-item Maximization Scale (Schwartz et al., 2002) with the goal of establishing its factor structure, reliability and validity. We also investigated the psychometric properties of several proposed refined versions of the scale. Four sets of analyses are reported. The first analysis confirms the 3-part factor structure of the scale and assesses its reliability. The second analysis identifies those items that do not perform well on the basis of internal, external, and judgmental criteria, and develops three shorter versions of the scale. In the third analysis, the three refined versions of the scale are cross-validated to confirm dimensionality, reliability, and validity. The fourth analysis uses an experiment in an investment decision making context to assess the reliability and nomological validity of the refined scales. These analyses lead us to conclude that a shorter, 6-item Maximization Scale performs best and should be used by future researchers. It is hoped that clarification of the conceptual underpinnings of the maximization construct and development of a refined scale will enhance its use among researchers across several of the social science disciplines.
Biasing simple choices by manipulating relative visual attention
Authors: Armel K. Carrie , Beaumel Aurelie , Rangel Antonio
Published: January 2023

Several decision-making models predict that it should be possible to affect real binary choices by manipulating the relative amount of visual attention that decision-makers pay to the two alternatives. We present the results of three behavioral experiments testing this prediction. Visual attention is controlled by manipulating the amount of time subjects fixate on the two items. The manipulation has a differential impact on appetitive and aversive items. Appetitive items are 6 to 11% more likely to be chosen in the long fixation condition. In contrast, aversive items are 7% less likely to be chosen in the long fixation condition. The effect is present for primary goods, such as foods, and for higher-order durable goods, such as posters.
Age-related differences in adaptive decision making: Sensitivity to expected value in risky choice
Authors: Levin Irwin P. , Weller Joshua A. , Pederson Ashley A. , Harshman Lyndsay A.
Published: January 2023

While previous research has found that children make more risky decisions than their parents, little is known about the developmental trajectory for the ability to make advantageous decisions. In a sample of children, 5-11 years old, we administered a new risky decision making task in which the relative expected value (EV) of the risky and riskless choice options was varied over trials. Younger children (age 5-7) showed significantly less responsiveness to EV differences than their parents on both trials involving risky gains and trials involving risky losses. For older children (age 8-11) this deficit was smaller overall but was greater on loss trials than on gain trials. Children of both ages made more risky choices than adults when risky choices were disadvantageous. We further analyzed these results in terms of children's ability to utilize probability and outcome information, and discussed them in terms of developing brain structures vital for decision making under uncertainty.
The application of Dempster-Shafer theory demonstrated with justification provided by legal evidence
Authors: Curley Shawn P.
Published: January 2023

In forecasting and decision making, people can and often do represent a degree of belief in some proposition. At least two separate constructs capture such degrees of belief: likelihoods capturing evidential balance and support capturing evidential weight. This paper explores the weight or justification that evidence affords propositions, with subjects communicating using a belief function in hypothetical legal situations, where justification is a relevant goal. Subjects evaluated the impact of sets of 1–3 pieces of evidence, varying in complexity, within a hypothetical legal situation. The study demonstrates the potential usefulness of this evidential weight measure as an alternative or complement to the more-studied probability measure. Subjects’ responses indicated that weight and likelihood were distinguished; that subjects’ evidential weight tended toward single elements in a targeted fashion; and, that there were identifiable individual differences in reactions to conflicting evidence. Specifically, most subjects reacted to conflicting evidence that supported disjoint sets of suspects with continued support in the implicated sets, although an identifiable minority reacted by pulling back their support, expressing indecisiveness. Such individuals would likely require a greater amount of evidence than the others to counteract this tendency in support. Thus, the study identifies the value of understanding evidential weight as distinct from likelihood, informs our understanding of the psychology of individuals’ judgments of evidential weight, and furthers the application and meaningfulness of belief functions as a communication language.
When good = better than average
Authors: Moore Don A.
Published: January 2023

People report themselves to be above average on simple tasks and below average on difficult tasks.This paper proposes an explanation for this effect that is simpler than prior explanations. The new explanation is that people conflate relative with absolute evaluation, especially on subjective measures.The paper then presents a series of four studies that test this conflation explanation.These tests distinguish conflation from other explanations, such as differential weighting and selecting the wrong referent.The results suggest that conflation occurs at the response stage during which people attempt to disambiguate subjective response scales in order to choose an answer.This is because conflation has little effect on objective measures, which would be equally affected if the conflation occurred at encoding.
“Am I going to be happy and financially stable?”: How American women feel when they think about financial security
Authors: Miron-Shatz Talya
Published: January 2023

Before the recent recession evoked general dismay and uncertainty, this study examined the relative contribution of income and the concern over financial security to life satisfaction. The degree to which such concerns permeate people's daily lives could be part of the broader concept of wealth, often measured through income and debt, and could help evaluate fiscal instruments promoting financial security. Study 1 (N = 267) used econometric methods to demonstrate that the consideration of financial security was as important to participants’ life satisfaction as their monetary assets. Further, outlook on financial security adds to the prediction of life satisfaction above the contribution of income. Content analysis revealed that nearly half the participants (N = 651, Study 2) mentioned financial concerns — retirement, college tuition, making ends meet, etc. — when asked to think about “the future” in an open-ended manner. These participants reported lower life satisfaction compared with women who did not raise such concerns. The link between concerns over financial security and life satisfaction, which cannot be fully accounted for by income alone, could guide policy decisions on whether to directly allocate resources toward increasing income or to focus on creating a social and financial safety net.
Evolution of the interpersonal conflict paradigm
Authors: Dhami Mandeep K. , Olsson Henrik
Published: January 2023

Using Brunswik’s (1952) lens model framework, Hammond (1965) proposed interpersonal conflict theory to explain the nature, source, and resolution of disagreement or “cognitive conflict” between parties performing judgment tasks. An early review by Brehmer (1976) highlighted the potential of this approach in, for example, understanding the structure of cognitive conflicts, and the effect of task and person variables on judgment policy change and conflict resolution. However, our bibliographic and content reviews from 1976 to the present day demonstrate that research on cognitive conflict using the lens model has declined sharply, while research on “task conflict” has grown dramatically. There has also been a shift to less theoretical precision and methodological rigor. We discuss possible reasons for these developments, and suggest ways in which lens model research on cognitive conflict can be revitalized by borrowing from recent theoretical and methodological advances in the field of judgment and decision making.
Modeling sequential context effects in judgment analysis: A time series approach
Authors: Beckstead Jason W.
Published: January 2023

In this article a broad perspective incorporating elements of time series theory is presented for conceptualizing the data obtained in multi-trial judgment experiments. Recent evidence suggests that sequential context effects, assimilation and contrast, commonly found in psychophysical judgment tasks, may be present in judgments of abstract magnitudes. A time series approach for analyzing single-subject data is developed and applied to expert prognostic judgments of risk for heart disease with an emphasis on detecting possible sequential context effects. The results demonstrate that sequential context effects do exist in such expert prognostic judgments. Contrast and assimilation were produced by cue series; the latter occurring more frequently. Experts also showed assimilation of prior responses that was independent of the cue series input. Time series analysis also revealed that abrupt or large trial-by-trial changes in the value of cues that receive the most attention in prognostic judgment tasks can disrupt the accuracy of these judgments. These findings suggest that a time series approach is a useful alternative to ordinary least squares regression, providing additional insights into the cognitive processes operating during multi-cue judgment experiments.
What’s bad is easy: Taboo values, affect, and cognition
Authors: Lichtenstein Sarah , Gregory Robin , Irwin Julie
Published: January 2023

Some decision situations are so objectionable or repugnant that people refuse to make a choice. This paper seeks to better understand taboo responses, and to distinguish choices that are truly taboo from those that are merely difficult or confusing. Using 22 scenarios that describe potentially taboo issues, Experiment 1 explores reasons for disapproval of the scenarios. We measure a large number of possible reasons for disapproval and a variety of preference responses (including willingness to accept), in order to test for subtleties in taboo responses. We also test cognitive and affective responses to the scenarios. Experiment 2 further explores the interaction, found in Experiment 1, between affective and cognitive factors. Taken as a whole, our results show that people are able to indicate their disapproval consistently across a variety of preference elicitation methods, that their disapproval is better understood as an attitude measure than as an economic valuation (even when the measure is in monetary terms), and that taboo responses are driven primarily by affect.
Attachment to land: The case of the land of Israel for American and Israeli Jews and the role of contagion
Authors: Rozin Paul , Wolf Sharon
Published: January 2023

This is a first study on attachment to national and sacred land and land as a protected value. A measure of attachment to the land of Israel is developed and administered to two groups, Jewish college students in Israel and the United States. Levels of land attachment are high and not significantly different in the two groups, with a great deal of variation. Land may become more important through being inhabited by a group over centuries. This is a positive contagion effect, and is opposed in some cases by negative contagion produced when the “enemies” live on the land for some period of time. We demonstrate a significant correlation of positive contagion sensitivity with attachment to the land of Israel. Unlike many other cases of the interaction of positive and negative contagion, negative contagion does not overwhelm positive contagion in the domain of land attachment. We also present evidence for linkages between political positions, religiosity, importance of Israel, Arab aversion, and vulnerability of Israel with attachment to land, but these do not fully account for the contagion effects. A number of significant differences between Israelis and Americans are described.
Genetic testing and risk interpretation: How do women understand lifetime risk results?
Authors: Hanoch Yaniv , Miron-Shatz Talya , Himmelstein Mary
Published: January 2023

Genetic screening for BRCA1 and BRCA2 gives women the opportunity for early detection, surveillance, and intervention. One key feature of genetic testing and counseling is the provision of personal lifetime risk. However, little attention has been paid to how women interpret lifetime risk information, despite the fact that they base screening, treatment and family planning decisions on such information. To study this vital issue, we set out to test the ability of women to choose the most appropriate interpretation of National Cancer Institute’s (NCI) message about lifetime risk of developing cancer for a woman with altered BRCA1 and BRCA2 genes. Participants included 277 women who had not undergone genetic testing or had cancer and 207 women who had undergone genetic testing or had cancer. Over 50% of the women who had not undergone genetic testing or had cancer and 40% of those who had undergone genetic testing or had cancer misunderstood NCI’s information. Furthermore, in line with a growing body of research, we found that high numeracy level (objective or subjective) is positively associated with a woman’s ability to correctly interpret NCI’s message.
Post-decision consolidation and distortion of facts
Authors: Svenson Ola , Salo Ilkka , Lindholm Torun
Published: January 2023

Participants decided whom of two patients to prioritize for surgery in three studies. The factual quantitative information about the patients (e.g., probability of surviving surgery) was given in vignette form with case descriptions on Visual Analogue Scales — VAS’s. Differentiation and Consolidation theory predicts that not only the attractiveness of facts but also the mental representations of objective facts themselves will be restructured in post-decision processes in support of a decision (Svenson, 2003). After the decision, participants were asked to reproduce the objective facts about the patients. The results showed that distortions of objective facts were used to consolidate a prior decision. The consolidation process relied on facts initially favoring the non-chosen alternative and on facts rated as less, rather than more important.
How different types of participant payments alter task performance

Researchers typically use incentives (such as money or course credit) in order to obtain participants who engage in the specific behaviors of interest to the researcher. There is, however, little understanding or agreement on the effects of different types and levels of incentives used. Some results in the domain of statistical reasoning suggest that performance differences — previously deemed theoretically important — may actually be due to differences in incentive types across studies. 704 participants completed one of five variants of a statistical reasoning task, for which they received either course credit, flat fee payment, or performance-based payment incentives. Successful task completion was more frequent with performance-based incentives than with either of the other incentive types. Performance on moderately difficult tasks (compared to very easy and very hard tasks) was most sensitive to incentives. These results can help resolve existing debates about inconsistent findings, guide more accurate comparisons across studies, and be applied beyond research settings.
A marketing science perspective on recognition-based heuristics (and the fast-and-frugal paradigm)
Authors: Hauser John
Published: January 2023

Marketing science seeks to prescribe better marketing strategies (advertising, product development, pricing, etc.). To do so we rely on models of consumer decisions grounded in empirical observations. Field experience suggests that recognition-based heuristics help consumers to choose which brands to consider and purchase in frequently-purchased categories, but other heuristics are more relevant in durable-goods categories. Screening with recognition is a rational screening rule when advertising is a signal of product quality, when observing other consumers makes it easy to learn decision rules, and when firms react to engineering-design constraints by offering brands such that a high-level on one product feature implies a low level on another product feature. Experience with applications and field experiments suggests four fruitful research topics: deciding how to decide (endogeneity), learning decision rules by self-reflection, risk reduction, and the difference between utility functions and decision rules. These challenges also pose methodological cautions.
Is variety the spice of life? It all depends on the rate of consumption

Is variety of the spice of life? The present research suggests that the answer depends on the rate of consumption. In three experiments, we find that, whereas a variety of stimuli is preferred to repetition of even a better-liked single stimulus when consumption is continuous, this preference reverses when the satiation associated with repetition is reduced by slowing down the rate of consumption. Decision makers, however, seem to under-appreciate the influence of consumption rate on preference for (and satisfaction with) variety. At high rates of consumption, they correctly anticipate their own, high, desire for variety, but at low rates of consumption people tend to overestimate their own desire for variety. These results complicate the picture presented by prior research on the “diversification bias”, suggesting that people overestimate their own desire for variety only when consumption is spaced out over time.
Risk communication with pictographs: The role of numeracy and graph processing

We conducted three studies to investigate how well pictographs communicate medical screening information to persons with higher and lower numeracy skills. In Study 1, we conducted a 2 (probability level: higher vs. lower) × 2 (reference information: yes vs. no) × 2 (subjective numeracy: higher vs. lower) between-subjects design. Persons with higher numeracy skills were influenced by probability level but not by reference information. Persons with lower numeracy tended to differentiate between a higher and a lower probability when there was no reference information. Study 2 consisted of interviews about the mental processing of pictographs. Higher numeracy was associated with counting the icons and relying on numbers depicted in the graph. Study 3 was an experiment with the same design as in Study 1, but, rather than using reference information, we varied the sequence of task type (counting first vs. non-counting first) to explore the role of the focus on numerical information. Persons with lower numeracy differentiated between higher and lower risk only when they were in the non-counting first condition. Task sequence did not influence the risk perceptions of persons with higher numeracy. In sum, our results suggest that pictographs may be useful for persons with higher and lower numeracy. However, these groups seem to process the graph differently. Persons with higher numeracy rely more on the numerical information depicted in the graph, whereas persons with lower numeracy seem to be confused when they are guided towards these numbers.
On the complexity of traffic judges' decisions
Authors: Leiser David , Schatzberg Dov-Ron

Professional judges in traffic courts sentence many hundreds of offenders per year. Using 639 case files from archives, we compared the Matching Heuristic (MH) to compensatory, weighing algorithms (WM). We modeled and cross validated the models on different subsets of the data, and took several other methodological precautions such as allowing each model to select the optimal number of variables and ordering and weighing the variables in accordance to different logics. We did not reproduce the finding by Dhami (2003), who found the MH to be superior to a compensatory algorithm in modeling bail-granting decisions. These simulations brought out the inner logic of the two family of models, showing what combination of parameters works best. It remains remarkable that using only a fraction of the variables and combining them non-compensatorily, MH obtained nearly as good a fit as the weighing method.
Moral identity in psychopathy

Several scholars have recognized the limitations of theories of moral reasoning in explaining moral behavior. They have argued that moral behavior may also be influenced by moral identity, or how central morality is to one’s sense of self. This idea has been supported by findings that people who exemplify moral behavior tend to place more importance on moral traits when defining their self-concepts (Colby & Damon, 1995). This paper takes the next step of examining individual variation in a construct highly associated with immoral behavior — psychopathy. In Study 1, we test the hypothesis that individuals with a greater degree of psychopathic traits have a weaker moral identity. Within a large online sample, we found that individuals who scored higher on a measure of psychopathic traits were less likely to base their self-concepts on moral traits. In Study 2, we test whether this reduced sense of moral identity can be attributed to differences in moral judgment, which is another factor that could influence immoral behavior. Our results indicated that the reduced sense of moral identity among more psychopathic individuals was independent of variation in moral judgment. These results suggest that individuals with psychopathic traits may display immoral behavior partially because they do not construe their personal identities in moral terms.
