Intimate Partner Violence and Subsequent Depression: Examining the Roles of Neighborhood Supportive Mechanisms

This study examines the direct effects of neighborhood supportive mechanisms (e.g., collective efficacy, social cohesion, social networks) on depressive symptoms among females as well as their moderating effects on the impact of IPV on subsequent depressive symptoms. A multilevel, multivariate Rasch model was used with data from the Project on Human Development in Chicago Neighborhoods to assess the existence of IPV and later susceptibility of depressive symptoms among 2959 adult females in 80 neighborhoods. Results indicate that neighborhood collective efficacy, social cohesion, social interactions, and the number of friends and family in the neighborhood reduce the likelihood that females experience depressive symptoms. However, living in areas with high proportions of friends and relatives exacerbates the impact of IPV on females’ subsequent depressive symptoms. The findings indicate that neighborhood supportive mechanisms impact interpersonal outcomes in both direct and moderating ways, although direct effects were more pronounced for depression than moderating effects. Future research should continue to examine the positive and potentially mitigating influences of neighborhoods in order to better understand for whom and under which circumstances violent relationships and mental health are influenced by contextual factors.     

Further evidence of renewal in automatically maintained behavior

Renewal is a relapse phenomenon that refers to the recurrence of a previously reduced behavior following a change in stimulus conditions. Muething et al. (2022) examined the phenomenology of renewal among individuals with automatically maintained challenging behavior treated at an outpatient clinic. We replicated their findings by retrospectively examining renewal across various topographies of automatically maintained behavior treated at an inpatient hospital, and we extended their work by also examining differences across subtypes of automatically maintained self-injurious behavior. The prevalence of renewal was comparable to that observed by Muething et al., supporting the notion that automatically maintained challenging behavior is susceptible to relapse phenomena. Furthermore, renewal was twice as likely to occur for individuals with Subtype 2 versus Subtype 1 self-injurious behavior, providing additional evidence of behavioral differentiation between subtypes. Our findings suggest that even after apparent stability in treatment, practitioners should remain vigilant for the recurrence of automatically maintained behavior during generalization.     

The effect of the first glimpse at a scene on eye movements during search

Previewing scenes briefly makes finding target objects more efficient when viewing is through a gaze-contingent window (windowed viewing). In contrast, showing a preview of a randomly arranged search display does not benefit search efficiency when viewing during search is of the full display. Here, we tested whether a scene preview is beneficial when the scene is fully visible during search. Scene previews, when presented, were 250 ms in duration. During search, the scene was either fully visible or windowed. A preview always provided an advantage, in terms of decreasing the time to initially fixate and respond to targets and in terms of the total number of fixations. In windowed visibility, a preview reduced the distance of fixations from the target position until at least the fourth fixation. In full visibility, previewing reduced the distance of the second fixation but not of later fixations. The gist information derived from the initial glimpse of a scene allowed for placement of the first one or two fixations at information-rich locations, but when nonfoveal information was available, subsequent eye movements were only guided by online information.     

Detection of Feigned Posttraumatic Stress Disorder: A Comparison of the MMPI-2 and PAI

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and Personality Assessment Inventory (PAI) were compared for detecting feigned posttraumatic stress disorder (PTSD) in a simulation research design. Participants were 85 undergraduates in one of three groups: PTSDs (n = 23), Fakers (n = 31), and Controls (n = 31). As expected, both the MMPI-2 and PAI discriminated PTSDs and Controls, with PTSDs scoring significantly higher on fake-bad validity scales and PTSD-relevant clinical scales. However, only the MMPI-2 discriminated Fakers and PTSDs, with Fakers scoring significantly higher on all MMPI-2 scales considered, but on only one PAI scale. Further, in logistic regression analyses the MMPI-2 demonstrated higher overall correct classification of PTSDs and Fakers than did the PAI. Although the MMPI-2 outperformed the PAI in detecting feigned PTSD, a substantial proportion of Fakers avoided detection by MMPI-2 fake-bad validity scales, suggesting that both tests are vulnerable to feigning of PTSD by motivated respondents with relatively limited coaching.     

Approach/avoidance motives, test emotions, and emotional regulation related to testing

This research stems from our program of work that focuses on understanding how students regulated their emotions related to testing. The primary goal for this study was to incorporate the approach/ avoidance motives into a model of emotional regulation related to testing. In addition, a secondary goal was to report on efforts at construct validation of the scores obtained during the refinement of the Emotional Regulation Related to Testing (ERT) Scale. Our results suggest that underlying beliefs, such as approach/avoid motives and the cognitive-appraisal process, of the ERT had both direct and indirect effects to both pleasant and unpleasant emotions related to testing. In addition, the ERT accounted for 56% of the variance in Pleasant and 87% of Unpleasant Test Emotions.     

Intercultural Study of Personal Space: A Case Study

The study of intercultural differences in personal space attempts to identify factors that could be helpful in guiding people from different cultures to live and work together in international ventures. The objective of this research was to measure interpersonal distance in a cross-cultural environment. Twenty-three participants classified in 4 cultural groups answered an 11-questions interview where the personal distance and orientation between seated interactants were measured. Results showed that Anglo Saxons used the largest zone of personal space, followed by Asians, then Caucasians, and, as expected, Mediterraneans and Latinos used the shortest distance. Where Latinos adopt a face-to-face position, Caucasians tend to orient themselves to the side of the interviewer, which has an impact on interpersonal communication.     

Dissecting the brain's internal clock: how frontal-striatal circuitry keeps time and shifts attention.

The ability of organisms to time and coordinate temporal sequences of events and to select particular aspects of their internal and external environments to which they will attend is vital to the organism's ability to adapt to the world around them. Numerous psychological theories have been proposed that describe how organisms might accomplish such stimulus selection and represent discrete temporal events as well as rhythm production. In addition, a large number of studies have demonstrated that damage to the frontostriatal circuitry appears to compromise the ability of organisms to successfully shift attention and behavior to adapt to changing temporal contexts. This suggests that frontostriatal circuitry is involved in the ability to make such shifts and to process temporal intervals. A selective review is accomplished in this article which focuses upon the specific neural mechanisms that may be involved in interval timing and set shifting. It is concluded that prefrontal cortex, substantia nigra pars compacta, pedunculopontine nucleus, and the direct and indirect pathways from the caudate to the thalamus may provide the neuroanatomical and neurophysiological substrates that underlie the organism's ability to shift its attention from one temporal context to another.     

Neural Correlates of Reward Processing in Adolescents With a History of Inhibited Temperament

ABSTRACT— Functional imaging data were acquired during performance of a reward-contingency task in a unique cohort of adolescents (ages 14–18 years) who were characterized since infancy on measures of temperamental behavioral inhibition. Neural activation was examined in striatal structures (nucleus accumbens, putamen, caudate) with a known role in facilitating response to salient reward-related cues. Adolescents with a history of behavioral inhibition, relative to noninhibited adolescents, showed increased activation in the nucleus accumbens when they believed their selection of an action would affect reward outcome. Neural responses did not differ between the two groups when participants made a prespecified response that they knew would result in reward or when they produced random motor responses that they knew would not be rewarded. These results link inhibited temperament and perturbed neural responses to reward-contingency cues.
