Sex Differences in Psychological Factors Associated with Social Discounting

The social discounting paradigm is a powerful means of quantifying altruism in humans, who are typically willing to forgo some amount of personal earnings in exchange for increased earnings for another person. The amount of money that people are willing to forgo decreases with increasing social distance. In this study, we examined variables related to sex, intolerance of uncertainty, and empathy, all of which are theorized to affect the social discounting rate. Participants (27 men and 28 women) completed measures of intolerance of uncertainty, empathy, and social discounting. We found sex differences in psychological predictors of social discounting: in women, empathy (but not intolerance of uncertainty) predicts the social discounting rate, while in men, social discounting is associated with intolerance of uncertainty (but not empathy). Possible neurobiological, social, and cognitive explanations for this sex difference are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Cognitive training programs for childhood cancer patients and survivors: A critical review and future directions

A robust literature has developed documenting neurocognitive late effects in survivors of leukemia and central nervous system (CNS) tumors, the most frequent cancer diagnoses of childhood. Patterns of late effects include deficits in attention and concentration, working memory, processing speed, and executive function, as well as other domains. As childhood cancer survivors are living longer, ameliorating deficits both in broad and specific neurocognitive domains has been increasingly recognized as an endeavor of paramount importance. Interventions to improve cognitive functioning were first applied to the field of pediatric oncology in the 1990s, based on strategies used effectively with adults who had sustained a traumatic brain injury (TBI). Compilation and modification of these techniques has led to the development of structured cognitive training programs, with the effectiveness and feasibility of such interventions currently an active area of research. Consequently, the purpose of this critical review is to: (1) review cognitive training programs intended to remediate or prevent neurocognitive deficits in pediatric cancer patients and survivors, (2) critically analyze training program strengths and weaknesses to inform practice, and (3) provide recommendations for future directions of clinical care and research.     

Individual differences in white matter microstructure predict semantic control

In everyday conversation, we make many rapid choices between competing concepts and words in order to convey our intent. This process is termed semantic control, and it is thought to rely on information transmission between a distributed semantic store in the temporal lobes and a more discrete region, optimized for retrieval and selection, in the left inferior frontal gyrus. Here, we used diffusion tensor imaging in a group of neurologically normal young adults to investigate the relationship between semantic control and white matter tracts that have been implicated in semantic memory retrieval. Participants completed a verb generation task that taps semantic control (Snyder & Munakata, 2008; Snyder et al., 2010) and underwent a diffusion imaging scan. Deterministic tractography was performed to compute indices representing the microstructural properties of the inferior fronto-occipital fasciculus (IFOF), the uncinate fasciculus (UF), and the inferior longitudinal fasciculus (ILF). Microstructural measures of the UF failed to predict semantic control performance. However, there was a significant relationship between microstructure of the left IFOF and ILF and individual differences in semantic control. Our findings support the view put forth by Duffau (2013) that the IFOF is a key structural pathway in semantic retrieval.     

Early Verb Learning: How Do Children Learn How to Compare Events?

An important problem verb learners must solve is how to extend verbs. Children could use cross-situational information to guide their extensions; however, comparing events is difficult. In 2 studies, researchers tested whether children benefit from initially seeing a pair of similar events (“progressive alignment”) while learning new verbs and whether this influence changes with age. In Study 1, 2.5- and 3.5-year-old children participated in an interactive task. Children who saw a pair of similar events and then varied events were able to extend verbs at test and differed from a control group; children who saw 2 pairs of varied events did not differ from the control group. In Study 2, events were presented on a monitor. Following the initial pair of events that varied by condition, a Tobii x120 eye tracker recorded 2.5-, 3.5-, and 4.5-year-olds’ fixations to specific elements of events (areas of interest) during the 2nd pair of events, which were the same across conditions. After seeing the pair of events that were highly similar, 2.5-year-olds showed significantly longer fixation durations to agents and to affected objects as compared with the all-varied condition. At test, 3.5-year-olds were able to extend the verb, but only in the progressive alignment condition. These results are important because they show children’s visual attention to relevant elements in dynamic events is influenced by their prior comparison experience, and they show that young children benefit from seeing similar events as they learn to compare events to each other.     

Beliefs in Equality for Women and Men as Related to Economic Factors in Central and Eastern Europe and the United States

Do economic indicators predict the general level of support for gender equality? This question was investigated in a sample of countries in Central and Eastern Europe, a region that has been undergoing rapid economic changes since the early 1990s. In this overall sample of male and female college students from ten countries, including the United States as a comparison, the predicted association between stronger beliefs in gender role egalitarianism and positive economic factors was generally supported. Also, consistent with other research, women were more in support of gender equality than men were. There was no support for a predicted trend in less support for gender equality over the time period of the present study.     

Sacred Canopies or Religious Markets? The Effect of County-Level Religious Diversity on Later Changes in Religious Involvement

Secularization theories, such as Berger's Sacred Canopy argument, hold that religious diversity leads to a decline in religious participation. Religious market models (e.g., Finke and Stark) argue the opposite. Voas, Olson, and Crockett found that nearly all of the vast research exploring this important question prior to 2002 was flawed due to a previously unrecognized noncausal statistical relationship between measures of religious diversity and measures of religious participation. Since 2002, this methodological issue has largely stymied research on this important topic. We first describe how, following Voas et al.’s recommendations, longitudinal models can overcome these problems. We then apply these methods to data measuring the religious composition of all U.S. counties found in the Religious Congregations and Membership Studies from 1980, 1990, 2000, and 2010. Using multilevel longitudinal regression models, we find that greater county-level religious diversity is followed by later declines in county-level religious participation rates. The negative effect size of religious diversity is large and robust to changes in the control variables and different methods of measuring religious diversity.     

Conceptualizing Personal and Extrapersonal Associations

We recently introduced the term ‘extrapersonal associations’ and defined them as information that is available in memory but that does not contribute to one's attitudes toward a given object ( Olson & Fazio, 2004 ). Here, we review our conceptualization of the term, contrast it to our conceptualization of attitudes as personal associations, and briefly summarize evidence that the Implicit Association Test, as it is traditionally employed, is influenced by extrapersonal associations. We discuss recent critiques of the concept and in so doing, elaborate upon the essence of the personal versus extrapersonal distinction. We conclude with speculations on the nature of extrapersonal associations, their origins, and relationship to attitudes.     

Evidence for the underestimation of implicit in-group favoritism among low-status groups

We question the evidence and the reasoning underlying recent research suggesting that members of low-status groups often fail to show in-group favoritism at the implicit level. Specifically, we argue the predominant measure revealing this pattern of group attitudes (the IAT) is influenced by extrapersonal associations, just the sort of information that would lead low-status groups to appear not to prefer their in-group. In the research reported here, respondents from low-status groups (African-Americans in Study 1 and homosexual males in Study 2) exhibited no in-group favoritism on the standard IAT, replicating previous research. However, reliable in-group favoritism by members of both groups was revealed on a personalized IAT [Olson, M. A., & Fazio, R. H. (2004). Reducing the influence of extrapersonal associations on the Implicit Association Test: Personalizing the IAT. Journal of Personality and Social Psychology, 86, 653-667] that reduces extrapersonal influences. We also rule out the possibility that differential error rates can account for the different patterns observed on the two versions of the IAT.     

Hypothalamic Pituitary Adrenal Axis Functioning in Reactive and Proactive Aggression in Children

The purpose of this study was to examine the association between hypothalamic-pituitary-adrenal axis (HPA-axis) reactivity and proactive and reactive aggression in pre-pubertal children. After a 30-min controlled base line period, 73 7-year-old children (40 males and 33 females) were randomly assigned to one of two experimental tasks designed to elicit fear (N = 33) or frustration (N = 32), or a validity check condition (N = 8). This was followed by a 60-min controlled regulation phase. A total of 17 saliva samples for cortisol analysis were collected including 12 post-stress samples at 5-min intervals. Reactive and proactive aggression levels were assessed via the teacher-completed Aggression Behavior Teacher Checklist (Dodge and Coie, J Pers Soc Psychol, 53(6), 1146–1158, 1987). Reactive aggression significantly predicted total and peak post-stress cortisol regardless of stress modality. Proactive aggression was not a predictor of any cortisol index. Examination of pure reactive, proactive, combined, or non-aggressive children indicated that reactive aggressive children had higher cortisol reactivity than proactive and non-aggressive children. Our data suggest that while an overactive HPA-axis response to stress is associated with reactive aggression, stress induced HPA-axis variability does not seem to be related to proactive aggression.
