Published: January 2023

AbstractQuality of life (QoL) is increasingly recognised as a more important measure of treatment success than prolongation of life. Assessment of QoL may aid decision-making for treatment or euthanasia. This study aimed to evaluate owners’ perceptions of factors affecting their horse's QoL and those factors that may contribute to their decision-making process for treatment or euthanasia of geriatric horses. A cross-sectional study was conducted, surveying a randomly selected sample of veterinary registered owners (n = 1,144) with horses aged ≥ 15 years, using a self-administered postal questionnaire. A section of this questionnaire contained 16 mixed-mode questions about the horse's QoL and factors influencing decisions on treatment. Horses from the cross-sectional survey were enrolled in a longitudinal study and, for cases of euthanasia, a further telephone questionnaire was completed to investigate factors influencing the owner's decision. Owners reported that the majority of geriatric animals enjoyed a high QoL, with 95% of owners rating their horse's QoL as good or excellent on an average day. However, increasing age corresponded negatively with many of the health-related QoL factors. Owners considered long-term diseases that cause chronic pain to affect their animal's QoL more than a disease causing a single episode of acute pain. The most important factors influencing choice of treatment options for a severe illness or injury were QoL after procedure, life-threatening disorders, painful/stressful procedures and veterinary advice. In conclusion, owner ratings and perceptions of factors affecting QoL of geriatric horses may prove useful in the development of a QoL assessment tool for ageing horses.

AbstractVery little is known about the fate of the large numbers of injured and orphaned wild animals taken to wildlife rehabilitation centres in the UK each year. We reviewed the reasons for admission and outcomes for 2,653 woodpigeons(Columba palumbus), 68% of which were juveniles, brought to an RSPCA wildlife rehabilitation centre in Cheshire, UK over a five-year period (2005-2009). Reasons for admission varied with the most common reason for adults and juveniles being ‘injury (cause uncertain)’ and ‘orphan’, respectively. Twenty-one percent of adults and 16% of juveniles had been attacked by cats. Sixty-five percent of adults and 37% of juveniles were euthanased on admission or within the first 48 h to prevent further suffering. Only 14% of adults and 31% of juveniles were released back into the wild. The remainder were either euthanased or died despite treatment more than 48 h after admission. Body condition on admission was not a good predictor of the likelihood of release, but age, weight on admission and severity of symptoms were significant factors. A reduction in the median number of days in care for those birds euthanased more than 48 h after being admitted was recorded for 2007 to 2009, possibly due to the introduction of radiography for all birds on admission. Leg-band recovery data for 15 birds revealed post-release survival ranging from 21-2,545 days (median = 231 days) compared to 1-2,898 days (median = 295) for non-rehabilitated birds.
Tags on seabirds: how seriously are instrument-induced behaviours considered?
Authors: Vandenabeele SP , Wilson RP , Grogan A 
Published: January 2023

AbstractEquipping birds with tags (defined as any item externally attached to birds, including transmitters, loggers and flipper bands, or implanted devices, such as transponders) gives particular insights into animal biology, although researchers may not give systematic consideration of tag impact. We examined 357 papers published between 1986 and 2009 where tags (excluding rings attached to birds’ legs) were used on seabirds, to examine the extent to which researchers considered deleterious effects. Fifty-one (14.3%) papers considered instrumentation effects in their abstract, 31 (60.8%) of which showed statistically significant effects on seabird biology. Of the total data set, 302 (84.6%) articles were classified as ‘indirect’ (with no stated aim to assess the influence of the equipment used) and although most of these (237; 76.5%) did discuss instrumentation effects, this accounted for less than a mean of 2% of the total length of the text. Despite a clear increase in the number of papers based on tagging technology for seabird study over the previous 24 years, there has been no corresponding increase in documentation of the effects of devices on their bearers. We suggest mechanisms by which this issue might be addressed.
Voluntary ingestion of buprenorphine in mice

AbstractBuprenorphine is a widely used analgesic for laboratory rodents. Administration of the drug in a desirable food item for voluntary ingestion is an attractive way to administer the drug non-invasively. However, it is vital that the animals ingest the buprenorphine-food-item mix as desired. The present study investigated how readily female and male mice (Mus musculus) of two different strains consumed buprenorphine mixed in a commercially available nut paste (Nutella®), and whether variation between genders and strains would affect the subsequent serum concentrations of buprenorphine. Buprenorphine at different concentrations mixed in Nutella® was given to male and female C57BL/6 and BALB/c mice in a complete cross-over study. Pure Nutella® or buprenorphine (1.0-3.0 mg kg−1 bodyweight [bw]) mixed in 10 g kg−1 bw Nutella® were given to the mice at 1500h. The mice were video recorded until the next morning, when blood was collected by submandibular venipuncture. The concentration of buprenorphine in the Nutella® mix did not affect the duration of ingestion in any of the groups. However, female mice consumed the Nutella® significantly faster than males. Repeated exposure significantly reduced the start time of voluntary ingestion, but not the duration of eating the mixture. These differences did not however affect the serum concentration of buprenorphine measured 17 h post administration.
Welfare science into practice: a successful case example of working with industry
Authors: Mullan S , Edwards SA , Butterworth A , Ward M , Whay HR , Main DCJ 
Published: January 2023

AbstractClose collaboration between science and industry is essential for the formulation of evidence-based welfare policies. However, there is a need to recognise and manage potential challenges that may arise during collaborative projects. An applied animal welfare science project evaluating the inclusion of welfare outcome measures into UK pig farm assurance, with a view to industry implementation, is used as a case example to illustrate potential challenges. This project encountered difficulties associated with differences in understanding and expectations, discussion of controversial welfare issues, challenges to personal values and conflict between academic and industry outcomes. With the assistance of an independent review conducted during the project, potential solutions were developed and successfully implemented. It is proposed that similar science-industry partnerships should allow sufficient time for dialogue, distinguish between experimental and applied science, ensure sufficient involvement from interested parties and use facilitation techniques to develop consensus.
The effect of increasing dietary fibre and the provision of straw racks on the welfare of sows housed in small static groups
Authors: Stewart CL , Boyle LA , O’Connell NE 
Published: January 2023

AbstractThis study assessed the effects of increasing dietary fibre levels in concentrate rations and providing access to straw in racks on the welfare of pregnant sows housed in small static groups. In a 2 × 2 factorial design experiment, 128 Large White × Landrace pregnant sows were offered one of two diets: (i) High fibre diet with 9% crude fibre, or (ii) Control diet with 4.5% CF, and one of two levels of access to a foraging substrate: (i) access to straw in racks or (ii) no straw. The study was replicated eight times using groups of four sows, and treatment periods lasted four weeks. Sows were housed in pens with voluntary cubicles and a slatted exercise area and were offered a wet diet twice a day. Back-fat levels were measured before sows were mixed into groups at 28 days post partum, and four weeks later. Aggressive interactions were recorded on the day of mixing, and injury scores were recorded one week post mixing. Scan sampling was used to collect data on general activity, posture and location of the sows, and on sham-chewing and bar-biting behaviours across the treatment period. In addition, detailed focal observations were carried out on all sows across the treatment period. Straw usage was also recorded. There were no treatment effects on changes in back-fat levels over the treatment period. Treatments had no effect on post-mixing aggression or on injury scores. However, focal observations showed that sows with access to straw were involved in fewer bouts of head-thrusting over the treatment period. Control diet sows spent more time inactive than sows on the high fibre diet, however high fibre diet sows spent more time lying with eyes closed than sows on the control diet. Sows on the high fibre diet with access to straw showed less sham-chewing and bar-biting behaviour than sows in other treatments. These results show that although a diet containing 9% crude fibre promoted resting behaviour, it was necessary to combine it with access to straw to reduce stereotypic behaviour ofsowsin small static groups.
The multiplicity of emotions: A framework of emotional functions in decision making
Authors: Pfister Hans-Rüdiger , Böhm Gisela 
Published: January 2023

AbstractA four-fold classification of emotions with respect to their functions in decision making is proposed. It is argued that emotions are not homogenous concerning their role in decision making, but that four distinct functions can be distinguished concerning emotional phenomena. One function is to provide information about pleasure and pain for preference construction, a second function is to enable rapid choices under time pressure, a third function is to focus attention on relevant aspects of a decision problem, and a fourth function is to generate commitment concerning morally and socially significant decisions. The pertinent literature on the relationship between emotion and decision making is reviewed, and it is concluded that most approaches fit into the proposed framework. We argue that a precise conceptualization of emotional phenomena is required to advance our understanding of the complex role of emotions in decision making.
Emotional tone and argumentation in risk communication
Authors: Hilton Denis 
Published: January 2023

AbstractIn this paper I explore how the evolution of emotional expression and co-operative planning in humans may inform the way they communicate about risks, and what implication this may have for models of rationality in risk communication. In particular, I focus on aspects of human language that enable successful co-ordination around shared tasks that involve the management of uncertainty by a group. I distinguish between performative (action-oriented) and constative (description-oriented) aspects of human communication, and argue that the human logical vocabulary of conditionals, quantifiers and probability expressions often conveys pragmatic signals that implicitly encourage or discourage a course of action that is under discussion. I review some studies that illustrate this perspective by highlighting the role of emotional undertone in risk communication and management, and show how it differs from existing models of risk communication and decision-making.
Trust in motives, trust in competence: Separate factors determining the effectiveness of risk communication
Authors: Twyman Matt , Harvey Nigel , Harries Clare 
Published: January 2023

AbstractAccording to Siegrist, Earle and Gutscher’s (2003) model of risk communication, the effect of advice about risk on an agent’s behavior depends on the agent’s trust in the competence of the advisor and on their trust in the motives of the advisor. Trust in competence depends on how good the advice received from the source has been in the past. Trust in motives depends on how similar the agent assesses the advisor’s values to be to their own. We show that past quality of advice and degree of similarity between advisors’ and judges’ values have separate (non-interacting) effects on two types of agent behavior: the degree of trust expressed in a source (stated trust) and the weight given to the source’s advice (revealed trust). These findings support Siegrist et al.’s model. We also found that revealed trust was affected more than stated trust by differences in advisor quality. It is not clear how this finding should be accommodated within Siegrist et al.’s (2003) model.
Deception and price in a market with asymmetric information
Authors: Eriksson Kimmo , Simpson Brent 
Published: January 2023

AbstractIn markets with asymmetric information, only sellers have knowledge about the quality of goods. Sellers may of course make a declaration of the quality, but unless there are sanctions imposed on false declarations or reputations are at stake, such declarations are tantamount to cheap talk. Nonetheless, in an experimental study we find that most people make honest declarations, which is in line with recent findings that lies damaging another party are costly in terms of the liar's utility. Moreover, we find in this experimental market that deceptive sellers offer lower prices than honest sellers, which could possibly be explained by the same wish to limit the damage to the other party. However, when the recipient of the offer is a social tie we find no evidence for lower prices of deceptive offers, which seems to indicate that the rationale for the lower price in deceptive offers to strangers is in fact profit-seeking (by making the deal more attractive) rather than moral.
Rebate subsidies, matching subsidies and isolation effects
Authors: Davis Douglas D. 
Published: January 2023

AbstractIn a series of recent experiments (Davis, Millner and Reilly, 2005, Eckel and Grossman, 2003, 2005a-c, 2006), matching subsidies generate significantly higher charity receipts than do theoretically equivalent rebate subsidies. This paper reports a laboratory experiment conducted to examine whether the higher receipts are attributable to a relative preference for matching subsidies or to an “isolation effect” (McCaffery and Baron, 2003, 2006). Some potential policy implications of isolation effects on charitable contributions are also considered.
Can avoidance of complications lead to biased healthcare decisions?
Authors: Amsterlaw Jennifer , Zikmund-Fisher Brian J. , Fagerlin Angela , Ubel Peter A. 
Published: January 2023

AbstractImagine that you have just received a colon cancer diagnosis and need to choose between two different surgical treatments. One surgery, the "complicated surgery," has a lower mortality rate (16% vs. 20%) but compared to the other surgery, the "uncomplicated surgery," also carries an additional 1% risk of each of four serious complications: colostomy, chronic diarrhea, wound infection, or an intermittent bowel obstruction. The complicated surgery dominates the uncomplicated surgery as long as life with complications is preferred over death.In our first survey, 51% of a sample (recruited from the cafeteria of a university medical center) selected the dominated alternative, the uncomplicated surgery, justifying this choice by saying that the death risks for the two surgeries were essentially the same and that the uncomplicated surgery avoided the risk of complications. In follow-up surveys, preference for the uncomplicated surgery remained relatively consistent (39%-51%) despite (a) presenting the risks in frequencies rather than percents, (b) grouping the 4 complications into a single category, or (c) giving the uncomplicated surgery a small chance of complications as well. Even when a pre-decision "focusing exercise" required people to state directly their preferences between life with each complication versus death, 49% still chose the uncomplicated surgery.People’s fear of complications leads them to ignore important differences between treatments. This tendency appears remarkably resistant to debiasing approaches and likely leads patients to make healthcare decisions that are inconsistent with their own preferences.
The availability heuristic in the classroom: How soliciting more criticism can boost your course ratings
Authors: Fox Craig R. 
Published: January 2023

AbstractThis paper extends previous research showing that experienced difficulty of recall can influence evaluative judgments (e.g., Winkielman & Schwarz, 2001) to a field study of university students rating a course. Students completed a mid-course evaluation form in which they were asked to list either 2 ways in which the course could be improved (a relatively easy task) or 10 ways in which the course could be improved (a relatively difficult task). Respondents who had been asked for 10 critical comments subsequently rated the course more favorably than respondents who had been asked for 2 critical comments. An internal analysis suggests that the number of critiques solicited provides a frame against which accessibility of instances is evaluated. The paper concludes with a discussion of implications of the present results and possible directions for future research.
Cognitive influences on risk-seeking by rhesus macaques
Authors: Hayden Benjamin Y. , Heilbronner Sarah R. , Nair Amrita C. , Platt Michael L. 
Published: January 2023

AbstractHumans and other animals are idiosyncratically sensitive to risk, either preferring or avoiding options having the same value but differing in uncertainty. Many explanations for risk sensitivity rely on the non-linear shape of a hypothesized utility curve. Because such models do not place any importance on uncertainty per se, utility curve-based accounts predict indifference between risky and riskless options that offer the same distribution of rewards. Here we show that monkeys strongly prefer uncertain gambles to alternating rewards with the same payoffs, demonstrating that uncertainty itself contributes to the appeal of risky options. Based on prior observations, we hypothesized that the appeal of the risky option is enhanced by the salience of the potential jackpot. To test this, we subtly manipulated payoffs in a second gambling task. We found that monkeys are more sensitive to small changes in the size of the large reward than to equivalent changes in the size of the small reward, indicating that they attend preferentially to the jackpots. Together, these results challenge utility curve-based accounts of risk sensitivity, and suggest that psychological factors, such as outcome salience and uncertainty itself, contribute to risky decision-making.
In the “I” of the storm: Shared initials increase disaster donations
Authors: Chandler Jesse , Griffin Tiffany M. , Sorensen Nicholas 
Published: January 2023

AbstractPeople prefer their own initials to other letters, influencing preferences in many domains. The “name letter effect” (Nuttin, 1987) may not apply to negatively valenced targets if people are motivated to downplay or distance themselves from negative targets associated with the self, as previous research has shown (e.g., Finch & Cialdini, 1989). In the current research we examine the relationship between same initial preferences and negatively valenced stimuli. Specifically, we examined donations to disaster relief after seven major hurricanes to test the influence of the name letter effect with negatively valenced targets. Individuals who shared an initial with the hurricane name were overrepresented among hurricane relief donors relative to the baseline distribution of initials in the donor population. This finding suggests that people may seek to ameliorate the negative effects of a disaster when there are shared characteristics between the disaster and the self.
Liberal-conservative differences in inclusion-exclusion strategy choice
Authors: Jasper John D. , Ansted Daniel 
Published: January 2023

AbstractInclusion and exclusion strategies for allocation of scarce goods involve different processes. The conditions under which one strategy is chosen in favor of the other, however, have not been fully explicated. In the present study, decision makers chose a single strategy after reading through descriptions of 16 potential organ recipients; they then narrowed the list of transplant candidates. Most liberals chose to use exclusion under conditions of abundance and inclusion under scarcity. In contrast, conservatives preferred an inclusion strategy under abundance and exclusion (though not significantly) under scarcity. Theoretical implications as well as ongoing work in inclusion-exclusion strategy choice, political ideology, and distributive justice are discussed.
“Head versus heart”: Effect of monetary frames on expression of sympathetic magical concerns
Authors: Rozin Paul , Grant Heidi , Weinberg Stephanie , Parker Scott 
Published: January 2023

AbstractMost American respondents give “irrational,” magical responses in a variety of situations that exemplify the sympathetic magical laws of similarity and contagion. In most of these cases, respondents are aware that their responses (usually rejections, as of fudge crafted to look like dog feces, or a food touched by a sterilized, dead cockroach) are not “scientifically” justified, but they are willing to avow them. We interpret this, in some sense, as “heart over head.” We report in this study that American adults and undergraduates are substantially less likely to acknowledge magical effects when the judgments involve money (amount willing to pay to avoid an “unpleasant” magical contact) than they are when using preference or rating measures. We conclude that in “head-heart” conflicts of this type, money tips the balance towards the former, or, in other words, that money makes the mind less magical.
Innumeracy and incentives: A ratio bias experiment
Authors: Dale Donald , Rudski Jeffrey , Schwarz Adam , Smith Eric 
Published: January 2023

AbstractThe Ratio-Bias phenomenon, observed by psychologist Seymour Epstein and colleagues, is a systematic manifestation of irrationality. When offered a choice between two lotteries, individuals consistently choose the lottery with the greater number of potential successes, even when it offers a smaller probability of success. In the current study, we conduct experiments to confirm this phenomenon and test for the existence of Bias as distinct from general irrationality. Moreover, we examine the effect of introducing a monetary incentive of varying size (depending on the treatment) on the extent of irrational choices within this framework. We confirm the existence of the Bias. Moreover, the existence of an incentive significantly reduces the extent of irrationality exhibited, and that this effect is roughly linear in response to changes in the size of the incentive within the magnitudes investigated.
