Effects of alcohol on person perception: a social cognitive neuroscience approach

The acute effects of alcohol on cognitive processing of expectancy violations were investigated using event-related brain potentials and a cued recall task to index attentional and working memory processes associated with inconsistency resolution. As predicted, expectancy-violating behaviors elicited larger late positive potentials (LPP) and were recalled better than expectancy-consistent behaviors. These effects were moderated by alcohol and the valence of initial expectancies. For placebo group participants, positive targets performing negative behaviors elicited the largest LPP responses and were recalled best. For those in the alcohol groups, negative targets behaving positively elicited the largest LPP and recall responses. These findings suggest that alcohol does not globally impair working memory processes in person perception but instead changes the nature of valenced information processing. Findings are discussed in the context of alcohol's effects on working memory processes, reward sensitivity, and the prefrontal cortical structures thought to mediate them.     

Contrast effects in judgments of health hazards

Researchers commonly use 2 models to explain contrast effects (CEs): the standard-of-comparison model and the set-reset model. The 2 models focus on the role of categorization to predict when a CE (instead of an assimilation effect) will happen, while minimizing the role of knowledge accessibility and relevance in determining whether any effect will occur. A 3rd model, the selective-accessibility model (F. Strack & T. Mussweiler, 1997), focuses on knowledge accessibility and relevance, but it is a model of assimilation effects in the anchoring bias. In the present study of CEs, the authors tested 3 predictions implied by the selective-accessibility model. The authors found a CE only when anchor- and target-rating dimensions matched and only in the 1st of multiple targets rated. The CE required a minimum amount of attention to the anchor. These results support the account that selective knowledge accessibility and relevance play an important role in CEs.     

Implicit Association Test: separating transsituationally stable and variable components of attitudes toward gay men

Implicit attitudes are conceived of as formed in childhood, suggesting extreme stability. At the same time, it has been shown that implicit attitudes are influenced by situational factors, suggesting variability by the moment. In the present article, using structural equation modeling, we decomposed implicit attitudes towards gay men into a person factor and a situational factor. The Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998), introduced as an instrument with which individual differences in implicit attitudes can be measured, was used. Measurement was repeated after one week (Experiment 1) or immediately (Experiment 2). Explicit attitudes towards gay men as assessed by way of questionnaires were positive and stable across situations. Implicit attitudes were relatively negative instead. Internal consistency of the implicit attitude assessment was exemplary. However, the within-situation consistency was accompanied by considerable unexplained between-situation variability. Consequently, it may not be adequate to interpret an individual implicit attitude measured at a given point in time as a person-related, trait-like factor.     

Measuring icon complexity: An automated analysis

Measures of icon designs rely heavily on surveys of the perceptions of population samples. Thus, measuring the extent to which changes in the structure of an icon will alter its perceived complexity can be costly and slow. An automated system capable of producing reliable estimates of perceived complexity could reduce development costs and time. Measures of icon complexity developed by Garcia, Badre, and Stasko (1994) and McDougall, Curry, and de Bruijn (1999) were correlated with six icon properties measured using Matlab (MathWorks, 2001) software, which uses image-processing techniques to measure icon properties. The six icon properties measured were icon foreground, the number of objects in an icon, the number of holes in those objects, and two calculations of icon edges and homogeneity in icon structure. The strongest correlates with human judgments of perceived icon complexity (McDougall et al., 1999) were structural variability (r _s = .65) and edge information (r _s = .64).     

An infant-based assessment of early lexicon acquisition

The majority of research on the acquisition of spoken language has focused on language production, due to difficulties in the assessment of comprehension. A primary limitation to comprehension assessment is maintaining the interest and attention of younger infants. We have developed an assessment procedure that addresses the need for an extensive performance-based measure of comprehension in the 2nd year of life. In the interest of developing an engaging approach that takes into account infants’ limited attention capabilities, we designed an assessment based on touchscreen technology. This approach builds upon prior research by combining standardization and complexity with an engaging infant-friendly interface. Data suggest that the touchscreen procedure is effective in eliciting and maintaining infant attention and will yield more extensive and reliable estimates of early comprehension than do other procedures. The software to implement the assessmentis available free of charge for academic purposes.     

Consumer information processing strategies in middle and late adulthood

The purpose of the present study was to investigate the extent to which performance of a complex cognitive task of a type resembling that encountered in everyday life is maintained through adulthood. A total of 80 subjects participated; 20 in their thirties, 20 in their fifties, 20 in their sixties, and 20 in their seventies. Subjects were asked to make preference judgments with respect to 32 pocket-size notebooks of a sort they might encounter as consumers in a stationery or variety store. Independently, they were also asked to express their preferences with respect to each of the four dimensions on which the notebooks varied. With only minor differences across age groups, most subjects demonstrated the ability to integrate their individual dimension preferences into a complex preference judgment of an object embodying those dimensions, in a logically consistent manner.     

Guilt assessment after retracted voluntary and coerced-compliant confessions in combination with exculpatory or ambiguous evidence

We investigated how voluntary confessions, coerced-compliant confessions, and no-confessions influenced guilt assessments in combination with other exculpatory or ambiguous evidence. In three experiments (total N = 808), participants studied case information and provided guilt assessments. As expected, in Experiment 1 and 2a, (i) voluntary confessions to protect a family member elicited stronger guilt attributions than no-confessions and (ii) ambiguous evidence led to stronger guilt attributions than exculpatory evidence. In Experiment 2b, voluntary confessions to protect a group-member (but not to protect a family-member) elicited stronger guilt attributions than no-confessions. Exculpatory eyewitness evidence elicited stronger guilt attributions than exculpatory DNA evidence and participants assigned more weight to exculpatory DNA than eyewitness evidence. Participants were able to discount coerced-compliant confessions when they received information about the interrogations (Experiments 2a/b), but did not consistently consider risk factors for (voluntary) false confessions outside the interrogation room when assessing guilt.     

Killing your children to hurt your partner: A South African perspective on the motivations for revenge filicide

The aim of the study was to investigate the offence characteristics and motivations for revenge filicides. Revenge filicide is an act where one parent kills their own offspring for retribution to hurt and upset the other parent. The cases of 20 revenge filicide murderers (14 male and six female) were analysed to determine the motivations and offence characteristics of revenge filicide offenders. It is the first South African study to highlight the motivations and associated characteristics in revenge filicides. Themes such as a loss of social identity due to rejection; extreme rage type anger; external locus of control; sadism; a desire to cause pain and a need to inflict harm are highlighted in this article. The initial emotional response may escalate from mild anger to a level of narcissistic rage which eventually culminates in the murdering of the child to punish and hurt the other parent and to restore control.     

Latinx Mental Health Scholars' Experiences with Cultural Adaptation and Implementation of Systemic Family Interventions

An increasing number of culturally adapted family-level interventions address mental health disparities with marginalized populations in the United States. However, with these developments many barriers have arisen, such as challenges with degree of cultural fit, engagement, and sustainability. We conducted 12 elite phenomenological interviews with mental health scholars involved in prevention and intervention family research with various Latinx communities within and outside of the United States. These scholars discussed their experiences of overcoming barriers in their research. We used thematic analysis to code and analyze participant responses, and our findings support the gaps in previous literature and highlight potential pathways to overcoming barriers in cultural adaptation research. Themes included the need for: (a) better understanding of the intersection between culture and context; (b) community-centered approaches to addressing implementation challenges; and (c) structural changes within institutional, governmental, and political levels. We discuss implications for researchers and practitioners working with Latinx families.
