Modelling individual difference in visual categorization

Recent years has seen growing interest in understanding, characterizing, and explaining individual differences in visual cognition. We focus here on individual differences in visual categorization. Categorization is the fundamental visual ability to group different objects together as the same kind of thing. Research on visual categorization and category learning has been significantly informed by computational modelling, so our review will focus both on how formal models of visual categorization have captured individual differences and how individual difference have informed the development of formal models. We first examine the potential sources of individual differences in leading models of visual categorization, providing a brief review of a range of different models. We then describe several examples of how computational models have captured individual differences in visual categorization. This review also provides a bit of an historical perspective, starting with models that predicted no individual differences, to those that captured group differences, to those that predict true individual differences, and to more recent hierarchical approaches that can simultaneously capture both group and individual differences in visual categorization. Via this selective review, we see how considerations of individual differences can lead to important theoretical insights into how people visually categorize objects in the world around them. We also consider new directions for work examining individual differences in visual categorization.     

Individual social capital and the implementation of entrepreneurial intentions: The case of Russia

The current research hypothesized that individual social capital facilitates the implementation of one's intention to start a business. The research samples were drawn from a sample of 2061 adult respondents: a sub‐sample of 269 adults who stated their intention to start their own business during the next two years (‘intenders’) and a matching sub‐sample of 270 who said they did not intend to do so (‘non‐intenders’). The study shows that the ‘intenders’ possessed greater individual social capital. These resources had a positive indirect impact (through increased perceived behavioural control and attitude) on their intention to start their own business.     

The Place of Purpose in Life in Women’s Positive Aging

Purpose in life is an orientation associated with energy, effectiveness, and optimism. A general trend is for purpose to decline in the later years, with unclear implications for positive aging. This article, however, takes a new approach to exploring the role of purpose. Using data from the Mills Study, a 55-year study of women’s adult development, we examine four sharp patterns of change in purpose on Ryff’s scale (1995 Ryff, C. D. (1995). Psychological well-being in adult life. Current Directions in Psychological Science, 4, 99–104. doi:10.1111/1467-8721.ep10772395[Crossref], [Web of Science ®] , [Google Scholar]) between ages 61 and 70: high at both times, low at both times, and changes from high to low or low to high. Guiding ideas are advanced about each kind of change and findings examined for each group. Looking at individual women's lives since childhood provides illustrative examples of each pattern. These lives show the impact of depression, inner resources, personality traits (especially Conscientiousness), attachment (secure and avoidant/dismissive styles), life situations (e.g., retirement), and events (e.g., early parental loss or widowhood), and of a motivation in one's 60s to grow or to transform regrets. Women differed in how traditional their lives were and in how much they associated purposiveness and goal attainment with life satisfaction. Implications for therapists include both helping women find the energy and commitment associated with purpose in life, and helping them value more process-oriented experiences such as appreciation, wonder, connection, and relationship. Emphasis on appreciation may become more common as women age. Positive aging is manifested in these ways, but also in acceptance and the courageous and steadfast coping with painful situations.     

The Development and Testing of a New Version of the Cognitive Reflection Test Applying Item Response Theory (IRT)

The cognitive reflection test (CRT) is a short measure of a person's ability to resist intuitive response tendencies and to produce a normatively correct response, which is based on effortful reasoning. Although the CRT is a very popular measure, its psychometric properties have not been extensively investigated. A major limitation of the CRT is the difficulty of the items, which can lead to floor effects in populations other than highly educated adults. The present study aimed at investigating the psychometric properties of the CRT applying item response theory analyses (a two‐parameter logistic model) and at developing a new version of the scale (the CRT‐long), which is appropriate for participants with both lower and higher levels of cognitive reflection. The results demonstrated the good psychometric properties of the original, as well as the new scale. The validity of the new scale was also assessed by measuring correlations with various indicators of intelligence, numeracy, reasoning and decision‐making skills, and thinking dispositions. Moreover, we present evidence for the suitability of the new scale to be used with developmental samples. Finally, by comparing the performance of adolescents and young adults on the CRT and CRT‐long, we report the first investigation into the development of cognitive reflection.

How can individual differences in autobiographical memory distributions of older adults be explained?

The reminiscence bump phenomenon has frequently been reported for the recall of autobiographical memories. The present study complements previous research by examining individual differences in the distribution of word-cued autobiographical memories. More importantly, we introduce predictor variables that might account for individual differences in the mean (location) and the standard deviation (scale) of individual memory distributions. All variables were derived from different theoretical accounts for the reminiscence bump phenomenon. We used a mixed location-scale logitnormal model, to analyse the 4602 autobiographical memories reported by 118 older participants. Results show reliable individual differences in the location and the scale. After controlling for age and gender, individual proportions of first-time experiences and individual proportions of positive memories, as well as the ratings on Openness to new Experiences and Self-Concept Clarity accounted for 29% of individual differences in location and 42% of individual differences in scale of autobiographical memory distributions. Results dovetail with a life-story account for the reminiscence bump which integrates central components of previous accounts.

Breaking face processing tasks apart to improve their predictive value in the real world: A comment on Ramon,Bobak, and White (2019)

In this commentary, I will expand on three aspects suggested by Ramon et al. (2019, British Journal of Psychology, 110, 461) to improve the predictive value of laboratory‐based tasks in real‐world applications. There are potential benefits that may arise from three interrelated considerations, particularly in terms of predicting agents’ susceptibility to errors in operational settings. The first is a proposal to conduct a detailed examination of performance on face processing tests rather than only analysing overall accuracy scores. The second involves considering non‐face‐related cognitive and meta‐cognitive sub‐processes involved in face processing tasks. The third highlights the contribution of superior recognisers in creating challenging tests that simulate difficult real‐world situations.     

Effects of Age on Dual-Task Walking While Listening

This study examined the effects of age on single- and dual-task listening and walking during virtual street crossing. Seventeen younger and 12 older adults participated. In each listening trial, three sentences were presented simultaneously from separate locations. Participants were instructed to report the target sentence. Predictability of the target sentence location was varied. Treadmill walking was measured using motion analysis. Measures included word recognition accuracy, head and trunk angles, and spatiotemporal gait parameters. Older adults exhibited a more upright head alignment and less variability in stride time during dual-tasking, particularly under less certain target sentence location conditions. Younger adults’ walking was unaffected by dual-task demands. Together, the results indicate greater postural prioritization in older adults than young.     

Methodological Challenges in the Study of Emotions in Politics and How to Deal With Them

This introductory article to the special issue zooms in on the literature on political emotions with a specific focus on methodological questions of “how to study” political emotions. To the extent that methodological matters are addressed in the extant literature, the associated challenges are often portrayed as a clash between social science and natural science disciplines, a clash frequently illustrated by the meeting between political science and neuroscience. Rather than being a clash between academic disciplines, this article argues that many of the methodological challenges facing emotional research have their origin in scholars' diverse views on the relationship between themselves as researchers and political emotions as a research object. In the light of this acknowledgment, the article encircles and discusses the methodological challenges associated with three key conceptual distinctions between: (1) individual and collective emotions, (2) emotions and reason, and between (3) involuntary political emotions and the strategic usage of political emotions. Using the contributions to this special issue as illustrations, the article argues in favor of moving beyond mutually exclusive dichotomies regarding these conceptual distinctions and offers pathways for dealing with current methodological challenges to emotional research. It points to methodological pluralism, transparency, and context‐sensitive research strategies.     

On Post‐apocalyptic and Doomsday Prepping Beliefs: A New Measure,its Correlates,and the Motivation to Prep

Post‐apocalyptic scenarios provide the basis for popular television shows, video games, and books. These scenarios may be popular because people have their own beliefs and visions about the apocalypse and the need to prepare. The prevalence of such beliefs might also hold societal relevance and serve as a type of projective test of personality. However, there are no quantitative accounts of post‐apocalyptic or prepping beliefs. As such, we conducted seven studies (N_total = 1034) to do so. In Studies 1 and 2, we developed a post‐apocalyptic and prepping beliefs scale, explored its correlates, and confirmed its structure and psychometric properties. In Study 3, we attempted to activate a ‘prepper’ mindset and further explore the correlates of the new scale. In Studies 4 and 5, we investigated covariations in daily feelings, thoughts, and events, and prepping beliefs. In Studies 6a and 6b, we compared scores from ‘real’ preppers and to a non‐prepping group. Overall, we found that post‐apocalyptic concerns and prepping beliefs are predictive of low agreeableness and humility, paranoia, cynicism, conspiracy mentality, conservatism, and social dominance orientation. We also found that increased belief in the need to prep is associated with God‐belief, negative daily experiences, and global political events. © 2019 European Association of Personality Psychology
