Saccadic re-referencing training with gaze-contingent FRL-'fixation': effects of scotoma type and size adaptation
Authors: Melnik Natalia , Pollmann Stefan
Published: March 2023

Foveal vision loss makes the fovea as saccadic reference point maladaptive. Training programs have been proposed that shift the saccadic reference point from the fovea to an extrafoveal location, just outside the area of vision loss. We used a visual search task (Ganesan et al., 2023) to train normal-sighted participants to fixate target items with a predetermined 'forced retinal location' (FRL) adjacent to a simulated central scotoma. We found that training was comparatively successful for scotomata that had either a sharp or blurry demarcation from the background. Completing the task with sharp-edged scotoma resulted in overall higher training gains. Training with blurry-edged scotoma, however, yielded overall better results when scotoma size was increased after training and participants needed to adapt to a more eccentric FRL, as may be necessary in patients with progressive degenerative eye diseases.
Reinforcement learning of adaptive control strategies

Published: March 2023

Humans can up- or downregulate the degree to which they rely on task information for goal directed behaviour, a process often referred to as cognitive control. Adjustments in cognitive control are traditionally studied in response to experienced or expected task-rule conflict. However, recent theories suggest that people can also learn to adapt control settings through reinforcement. Across three preregistered task switching experiments (n=415), we selectively rewarded correct performance on trials with either more (incongruent) or less (congruent) task-rule conflict. Results confirmed the hypothesis that people rewarded more on incongruent trials showed smaller task-rule congruency effects, thus optimally adapting their control settings to the reward scheme. Using drift diffusion modelling, we further show that this reinforcement of cognitive control may occur through conflict-dependent within-trial adjustments of response thresholds after conflict detection. Together, our findings suggest that, while people remain more efficient at learning stimulus-response associations through rewards, they can similarly learn cognitive control strategies through reinforcement.
Introducing the Meat Consumption Scale: Psychometric Properties and Convergent Validity
Authors: Camilleri Lauren , Jago Andrew , Rehman Abdul , Gill Peter Richard
Published: March 2023

Background: The psychology of eating meat has emerged as a major field of study due to growing awareness of the negative impacts of excessive meat consumption on human and planetary health. However, given the critical importance of psychometrically valid measurement tools in quantitative research, it is concerning that studies have largely relied on unvalidated, ad hoc survey instruments to measure meat consumption. To address this methodological gap this study aimed to develop and validate a self-report questionnaire to measure an individual’s meat consumption and meat-eating intentions.Methods: The questionnaire was developed and validated through exploratory factor analysis (sample 1: N=183 Australians) and confirmatory factor analysis (sample 2: N=495 Australians). Convergent validity was assessed through correlation analyses conducted in both samples to determine the scale's association with demographic variables and ten meat-related constructs. Internal consistency reliability was assessed with mean inter-item correlations and corrected total-item correlations.Results: Exploratory factor analysis did not identify a latent meat-eating intention scale, but did reveal a unidimensional latent factor representing total meat consumption, which was named The Meat Consumption Scale (MCS). Confirmatory factor analysis verified the unidimensional structure of the MCS, with all model fit indices demonstrating excellent model fit. Significant correlations in the hypothesised directions between the MCS, ten meat-related constructs, and demographic variables provided evidence of convergent validity. Internal consistency reliability of the MCS was acceptable in both samples when evaluated by mean inter-item correlations and corrected item-total correlations. Conclusions: The Meat Consumption Scale (MCS) is the first psychometrically validated tool designed to measure an individual's meat consumption requiring a fast (<5 mins) one-time assessment. This 12-item self-report questionnaire measures consumption of land-based animal meat—red meat, poultry products, pork products, and other processed meats—over the past two-week period and is indicative of trait meat-eating patterns. The MCS is ideal for cross-sectional and longitudinal use in research and applied contexts. Further validation of the scale, including cultural adaptations, is recommended.
How voters think about the electoral relevance of the Supreme Court
Authors: Davis Nicholas , Hitt Matthew P.
Published: March 2023

Despite sporadic claims that elections may serve as a referendum on the Supreme Court, prevailing theories of diffuse support imply that voters mostly ignore the Court. This paper tests that thesis. Using recent, nationally-representative survey data, Study 1 shows that, despite the Supreme Court being ranked as a middling issue of importance, high levels of diffuse support increase its perceived electoral relevance. Study 2 deploys a survey experiment, which illustrates that candidates who support (oppose) reform are viewed as stronger candidates among Democrats (Republicans), as well as more prototypically liberal (conservative). The sorting of demand for reform along partisan lines dovetails with a sorting of diffuse support, which presents an inherent irony for the prospects of reform: while low-legitimacy Democrats may support reform, lower levels of diffuse support are also linked to weaker perceptions of reform’s electoral relevance – providing mixed signals to candidates about the demand for reform.
Empirical Investigation of the Relationship between Construals of Structural Racism and Attitudes toward Critical Race Theory

Published: March 2023

An uptick in U.S. White Americans’ structural understanding of racism alongside opposition to critical race theory (CRT) and acknowledgement of the historical and pervasiveness of racism reflects a social paradox. How is it that the U.S. White Americans can seemingly acknowledge structural racism without supporting its logical corollary arguments? CRT itself might have the answer in the form of interest convergence. CRT posits that U.S. White Americans only support aspects of anti-racist ideology that benefit their group, suggesting that something about supporting structural racism is beneficial. In two studies (N = 968), we test whether differences in the construal of structural racism in concrete versus abstract ways can help explain this paradox, assuming that construing structural racism in more abstract ways absolves the self, and one’s group, from racial wrongdoing. Across multiple operationalizations of abstraction (i.e.., the use of “I”, “we”, Brysbaert Concreteness Index, and a concreteness manipulation) we find partial evidence that abstraction leads to a reduction in support for the historic and endemic nature of racism for U.S. White but not Black Americans. We discuss the implications of our findings for the future of CRT and the fight for justice.
The virtual crime scene: Virtual reality context reinstatement as a means to increase the quality of eyewitness statements.
Authors: Timmer Jeroen , de Vries Peter W. , Gosselt Jordy F.
Published: March 2023

Purpose: Eyewitness statements often determine the direction and the success of police investigations. However, eyewitnesses’ recollection of events may become inaccurate or even incorrect over time. Moreover, eyewitnesses’ expressed confidence in the quality of their statements tends to be a rather weak indicator of actual quality. The current study explores how different types of context reinstatement compare in terms of quality of eyewitness statements and how they influence the confidence-quality relationship. Of particular interest is a new type of context reinstatement: virtual context reinstatement.Methods: Participants (N = 98) were asked to take part in a group experiment in which an incident was staged. A week later, participants were subjected to virtual context reinstatement (VCR), physical context reinstatement (PCR), mental context reinstatement (MCR), or a no context reinstatement (control) procedure, and were subsequently asked to give an eyewitness statement. Results: During free recall, eyewitness statements in both the VCR and PCR conditions contained significantly less confabulated details compared to statements of participants in the control group. During cued recall, participants in the VCR condition reported more correct details in their statements than participants in the MCR and PCR conditions. Moreover, VCR appears to result in a stronger confidence-quality relationship compared to the other types context reinstatement. Conclusions: PCR and VCR showed fewest confabulated details in eyewitness statements and are therefore most beneficial to police investigations. The stronger confidence-quality relationship as a result of VCR can help to support the decision-making process of police investigators and other professionals who rely on eyewitness statements.
Because Excellencism Is More than Good Enough: On the Need to Distinguish the Pursuit of Excellence from the Pursuit of Perfection
Authors: Gaudreau Patrick , Schellenberg Benjamin J. I. , Gareau Alexandre , Kljajic Kristina , Manoni-Millar Stephanie
Published: March 2023

An unresolved and controversial issue in the perfectionism literature is whether perfectionism is beneficial, harmful, or unneeded. The Model of Excellencism and Perfectionism (MEP) was recently developed to address this question by distinguishing the pursuit of perfection from the pursuit of excellence (Gaudreau, 2019). In this article, we report the results of the first empirical test of the core assumptions of the MEP. Across 5 studies (total N = 2,157), we tested the conceptual, functional, and developmental distinctiveness of excellencism and perfectionism. In Study 1, exploratory and confirmatory factor analyses with two samples supported the hypothesized two-factor structure of the newly developed Scale of Perfectionism and Excellencism (SCOPE). Study 2 provided evidence of convergent and discriminant validity from scores obtained from the SCOPE, and showed that, over and above excellencism, perfectionism was not associated with additional benefits (e.g., life satisfaction) or harms (e.g., depression). Studies 3-4 focused on the academic achievement of undergraduates and showed that, compared to excellence strivers, perfection strivers more often aimed for perfect A+ grades (Study 3), but in fact achieved worse grades (Study 4). Study 5 adopted a four-wave longitudinal design with undergraduates and showed that excellencism and perfectionism were associated with an upward and a downward spiral of academic development. Overall, the results support the core assumptions of the MEP and show that perfectionism is either unneeded or harmful.
Neural Networks Need Real-World Behavior
Authors: Li Aedan Yue , Mur Marieke
Published: March 2023

Bowers et al. (2022) propose to use controlled behavioral experiments when evaluating deep neural networks as models of biological vision. We agree with the sentiment and draw parallels to the notion that “neuroscience needs behavior”. As a promising path forward, we suggest complementing image recognition tasks with increasingly realistic and well-controlled task environments that engage real-world object recognition behavior.
Not all objects are created equal: the object benefit in visual working memory is supported by greater recollection-like memory, but only for memorable objects
Authors: Torres Rosa E. , Duprey Mallory , Campbell Karen L. , Emrich Stephen M
Published: March 2023

Visual working memory is thought to have a fixed capacity limit. However, recent evidence suggests that a greater number of real-world objects than simple features (i.e., colors) can be maintained, an effect termed the object benefit. Here, we examined whether this object benefit in visual working memory is due to qualitatively different memory processes employed for meaningful stimuli compared to simple features. In online samples of young adults, real-world objects were better remembered than colors, had higher measures of recollection, and showed a greater proportion of high-confidence responses (Exp. 1). Objects were also remembered better than their scrambled counterparts (Exp. 2), suggesting that this benefit is related to semantic information, rather than visual complexity. Critically, the specific objects that were likely to be remembered with high confidence were highly correlated across experiments, consistent with the idea that some objects are more memorable than others. Visual working memory performance for the least-memorable objects was worse than that of colors and scrambled objects. These findings suggest that real-world objects give rise to recollective, or at least high-confidence, responses at retrieval that may depend on activation of semantic features, but that this effect is limited to certain objects.

Reliability and Validity of Behavioral Economic Measures: A Review and Synthesis of Discounting and Demand
Authors: Miller Brandon P. , Reed Derek D , Amlung Michael
Published: March 2023

This review aimed to synthesize the literature on the reliability and validity of behavioral economic measures of demand and discounting in human research, introduce behavioral economic research methodologies for studying addictive behaviors, discuss gaps in the current literature, and review areas for future research. A total of 34 studies were included in this review. The discounting literature shows similar responding regardless of whether hypothetical or actual outcomes are used, though people tend to discount the outcome presented first more steeply, suggesting order effects. While delay discounting measures seem to show temporal stability, exceptions were found for probability and experiential discounting tasks. The demand literature also demonstrates similar responding regardless of outcome type; however, some demand indices showed exceptions. Randomized price sequences tended to show modest increases in Omax and α and modestly higher rates of inconsistent or nonsystematic responses compared to sequential price sequences. Demand indices generally show temporal stability, although stability is weaker the larger the time interval between test sessions. Future studies would benefit by examining addictive commodities beyond alcohol, nicotine, and money, examining temporal stability over longer time intervals, using larger delays in discounting tasks, and using larger sample sizes.
Short term solutions to biodiversity conservation in portfolio construction: forward looking disclosure and taxonomy-based metrics
Authors: Layman Hannah , Akcakaya H. Resit , Irwin Amanda , zu Ermgassen Sophus , Addison Prue , Burgman Mark
Published: March 2023

Demand is increasing amongst investors to create portfolios that encourage positive outcomes for biological diversity. The evolution of investment strategies for transitions to zero carbon over the last two decades provides insights that will assist in shaping strategies for biodiversity-positive investments. Many emerging approaches to capture company impact and dependence on biodiversity focus on nature-related threats to an organisation by looking at the composition of local ecosystems and sustaining ecosystem services. Other approaches have a different objective function, focusing on minimizing an organisation’s contribution to risks of species extinction by using data sets such as the IUCN’s Red List of Threatened Species. However, in both cases, many of the threat assessments that could link corporate activities to impacts are incomplete and omit critical information, and the models that use these links are largely untested for use in portfolio construction. If the investment community focuses on biodiversity without sufficient forethought, there is a risk of entrenching metrics with significant flaws. In this paper we suggest that until such time as species threat assessments are complete and the metrics to which they contribute are fully developed and tested for use, interim approaches to guide investments can leverage off disclosure-based or taxonomy-based approaches developed for climate investing. We present and discuss two potential such metrics, a Biodiversity Management Quality metric and a Biodiversity Revenues metric.
“Italians, first! Unpacking the link between nationalism and immigrant discrimination”,
Authors: GUGLIELMI SIMONA
Published: March 2023

The article investigates, theoretically and empirically, the mechanisms underlying the link between the normative and affective dimensions of national identity, perceived threats (realistic and symbolic), and outgroup trust‐related emotions as predictors of support for migrant employment policy based on the nativist argument. The National Identity Threat Trust model (NITT) is theorized and tested. Empirically, structural equation modelling was performed on survey data from the last wave of EVS Italy (2017). The analysis showed that the ethnic majoritarian conception has a positive impact on perceived collective threats (realistic and symbolic) and trust‐related emotions, which in turn influence support for discriminatory migrant employment policy. The civil conception contributes indirectly to increasing support for native employment priority via positive association with the perception of economic and symbolic threats. Citizens close to right-wing nativist parties exhibit a similar relationship structure to the rest of population. However, the “nativist” politicization of attitudes towards immigrants makes the symbolic threat a particularly salient factor.

In industry, electric motors play an important role as energy for motion in equipment in the production process. During the starting process, it can draw currents up to 5 to 7 times the nominal current when working normally. So that it can have a bad effect on the electric motor and the surrounding electrical equipment. The method that uses the ABB PSTTX 570 Soft Starting is through the method of starting an electric motor using a thyristor circuit. The soft start method is suitable for cars that are quite powerful. The purpose of the soft start method is to obtain a smaller starting current, to reduce the impact of large peak currents during the starting process and to achieve a constant rated speed. In this method, the current in the motor flows slowly during starting until it reaches the rated value within a certain period of time certain. Soft starting measurable display when motor voltage is 34%, moor current is 7.3 A active power is 0.14 kW when motor voltage is 70% motor current is 1782.5 A with active 371.09 kW and when motor voltage is 100% up motor 111.6 A with an active power of 23.65 kW. In terms of size, the advantage of the soft starter is that it is simpler than the inverter starting equipment.

The world uses all resources to meet daily electrical energy needs so that shortly, we will run out of ore/mineral/petroleum, a source of electrical energy. As a result, renewable energy solutions have reached the current great demand to save natural resources and solve the energy crisis. Solar energy is rapidly gaining notoriety as an essential means of expanding renewable energy resources. Solar panels are devices that cleanly convert sunlight into electricity and offer a practical solution to the problem of generating electricity in remote areas. Therefore, it is significant for those of us in electrical engineering to understand the technology associated with this field. The solar panel system must be maximized to make solar energy more feasible and efficient than fossil energy. An automatic sun position tracking or solar tracker is a viable approach to optimizing the efficiency of a solar panel system. A solar tracker is a system that controls the movement of solar panels so that they are always aligned with the sun's position. The solar tracker uses a dual-axis system to align the solar panels with the sun's position. By using a solar tracker, it is expected that the solar panel system will produce maximum output power.

Pada praktinya perusahaan membuat langkah stategis untuk memaksimalkan pemahaman pekerjanya terhadap aktivitas berisiko tinggi yang dihadapi, seperti adanya Do and Dont Policy (DDP) untuk meminimasi kecelakaan kerja. Namun berdasarkan data observasi, DDP dapat lebih dioptimalkan karena terdapat signifikansi angka Kejadian Tidak Aman (KTA)/Tindakan Tidak Aman (TTA) masih ditemukan pada tahun 2020, terutama pada TTA di tahun 2020 berkaitan erat dengan DDP. Oleh karena itu, pada studi ini bertujuan untuk memberikan rekomendasi peningkatan proses bisnis guna memperkuat retensi pembelajaran karyawan melalui sistem yang responsive dan adaptif terhadap kompetensi karyawan menggunakan metode kualitatif dengan teknik wawancara dan menganalisis permasalahan menggunakan Fault Tree Analysis (FTA). Seletah dilakukan penelitian ini, diperoleh tiga usulan dari hasil elaborasi dan wawancara tingkat lanjut yang dapat digunakan sebagai peningkatan proses bisnis. Pertama Sistem Test Harian, Smart Coaching, dan Pembelajaran Micro. Pada akhirnya studi ini mampu memberikan Implikasi strategi yang tepat untuk meningkatkan dan mengembangkan proses bisnis training dan kompetensi karyawan pertambangan secara matang dan inkremental sesuai dengan kebutuhan penerima manfaat.

The relayout of the production facilities needs to be carried out by a manufacturer if there is a new product produced that has a different material flow from the existing product. If the layout of the initial facility is maintained, the material flow will become irregular and lead to long material transfer distances and substantial material handling costs. One method that can be used for relayout production facilities is the fractal method. This method is suitable for job shop system because it could provide a high level of flexibility and low total material handling costs. The case study used in this research, which is a spare part manufacturer that initially applied the by-process layout. The initial layout is less flexible in line with the current manufacturing conditions where there are additional variations in the types of products produced. The distance between machines with different types becomes far apart. By relayout of the production facilities using the fractal method, the material handling cost savings of IDR 157,868.64/week or 60.75%/week and the total savings in moving distance is 186,365 meters/week or 38.93%/week. Fractal method is proven to be used to design the layout of production facilities and reduce material handling costs and material transfer distances.
