Testing the long-term efficacy of a prevention program for improving marital conflict in community families

Family-focused prevention programs for community samples have potentially broad, clinically relevant implications but few studies have examined whether any program benefits continue to be observed over the long term. Although benefits of a marital conflict focused parent education program, the Happy Couples and Happy Kids (i.e., HCHK) program, were supported in a study based on pre-test, post-test, 6-month follow-up, and 1-year follow-up assessments, the longer-term stability of treatment effects has not been established. Couples with children between 4 and 8 years of age who had previously participated in the HCHK study completed a two-year follow-up, including a parent-only group (PO, n = 12); parent-child group (PC, n = 15); and a self-study group (SS, n = 12). Greater knowledge about the effects of marital conflict on families and behavioral improvements in constructive conflict, and specifically in problem-solving behaviors, were observed at the two-year follow-up for couples who received the HCHK program. Reflecting an innovative analysis of mediating mechanisms, change-to-change analyses showed that these changes were linked with improvements in other family processes over time, including marital satisfaction, parenting and child adjustment. The findings support the relatively long-term efficacy of brief, psychoeducational programs for educating community samples about marital conflict and family processes.     

Black churches and HIV/AIDS: factors influencing congregations’ responsiveness to social issues

The ambivalent response of many black churches to current social issues has caused some scholars to question the centrality of black churches within African-American communities. Using a nationally representative sample of black congregations, this study engages the debate about the institutional centrality of black churches by focusing on their response to HIV/AIDS. Although many congregational studies treat black churches as a monolithic whole, this analysis identifies heterogeneity among black churches that shapes their responsiveness to social issues. Contrary to prior claims, a congregation's liberal-conservative ideological orientation does not significantly affect its likelihood of having an HIV/AIDS program. Beyond assessing churches’ internal characteristics, this study uses institutional theory to analyze churches as open systems that can be influenced by their surrounding environment. It demonstrates that externally engaged congregations are significantly more likely to have a program. These results indicate that black churches maintain institutional centrality by engaging their external environment.     

This is your brain on violent video games: Neural desensitization to violence predicts increased aggression following violent video game exposure

Previous research has shown that media violence exposure can cause desensitization to violence, which in theory can increase aggression. However, no study to date has demonstrated this association. In the present experiment, participants played a violent or nonviolent video game, viewed violent and nonviolent photos while their brain activity was measured, and then gave an ostensible opponent unpleasant noise blasts. Participants low in previous exposure to video game violence who played a violent (relative to a nonviolent) game showed a reduction in the P3 component of the event-related brain potential (ERP) to violent images (indicating physiological desensitization), and this brain response mediated the effect of video game content on subsequent aggressive behavior. These data provide the first experimental evidence linking violence desensitization with increased aggression, and show that a neural marker of this process can at least partially account for the causal link between violent game exposure and aggression.     

Effects of workshop trainings on evidence-based practice knowledge and attitudes among youth community mental health providers

Enhancing the public health impact of evidence-based practices (EBPs) in usual care settings is a key priority of the National Institute of Mental Health. Longitudinal data from community mental health providers (N = 268) participating in a series of state-sponsored workshops in modular approaches to EBPs for youth are presented. EBP workshop attendance for youth anxiety resulted in increased knowledge for EBPs for anxiety (and not other conditions) and EBP workshop attendance for youth disruptive behaviors resulted in increased knowledge for EBPs for disruptive behaviors (and not other conditions). Providers' tendencies toward incorrectly classifying non-EBP therapies as evidence-based increased over time, suggesting that providers over-generalize the EBP label as a result of attending these types of workshops. Regarding EBP attitudes, most measures of attitudes improved when providers attended a workshop. Additionally, an overly inclusive view of what constitutes an EBP at intake was related to significant decreases in openness to trying EBPs over time, whereas more positive attitudes at intake was related to achieving a more refined view of what constitutes an EBP over the course of attending trainings. Study limitations and implications for implementation of EBPs in usual care settings are discussed.     

Too fatigued to care: Ego depletion,guilt, and prosocial behavior

Although guilt feels bad to the individual, it is good for society because guilty feelings can prompt people to perform good deeds. This study tests whether fatigue decreases guilty feelings and subsequent prosocial behavior. Participants were randomly assigned to a depletion condition in which they watched a movie about butchering animals for their meat or skin and were told to express no emotions, or to a no-depletion condition in which they watched the same movie, but could express their emotions. Having participants play a game in which another person was punished for their errors induced guilt. Finally, participants played a dictator game in which they could leave money for the next participant. After the experiment, participants could also anonymously donate money to an anti-AIDS charity. The results showed that depleted participants felt less guilty than did non-depleted participants, and the less guilty participants felt the less helpful they were.     

Flies on the wall are less aggressive: Self-distancing “in the heat of the moment” reduces aggressive thoughts,angry feelings and aggressive behavior

People tend to ruminate after being provoked, which is like using gasoline to put out a fire—it feeds the flame by keeping aggressive thoughts and angry feelings active. In contrast, reflecting over past provocations from a self-distanced or “fly on the wall” perspective reduces aggressive thoughts and angry feelings. However, it is unclear whether people can self-distance “in the heat of the moment” (i.e., immediately after being provoked), and if they can, whether doing so reduces actual aggressive behavior. Two experiments addressed these issues. The results indicated that provoked participants who self-distanced had fewer aggressive thoughts and angry feelings (Experiment 1) and displayed less aggressive behavior (Experiment 2) than participants who self-immersed or were in a control group. These findings demonstrate that people can self-distance in the heat of the moment, and that doing so reduces aggressive thoughts, angry feelings, and aggressive behavior.     

A reproductive threat-based model of evolved sex differences in jealousy

Although heterosexual women and men consistently demonstrate sex differences in jealousy, these differences disappear among lesbians and gay men as well as among heterosexual women and men contemplating same-sex infidelities (infidelities in which the partner and rival are the same sex). Synthesizing these past findings, the present paper offers a reproductive threat-based model of evolved sex differences in jealousy that predicts that the sexes will differ only when the jealous perceivers' reproductive outcomes are differentially at risk. This model is supported by data from a web-based study in which lesbians, gay men, bisexual women and men, and heterosexual women and men responded to a hypothetical infidelity scenario with the sex of the rival randomly determined. After reading the scenario, participants indicated which type of infidelity (sexual versus emotional) would cause greater distress. Consistent with predictions, heterosexual women and men showed a sex difference when contemplating opposite-sex infidelities but not when contemplating same-sex infidelities, whereas lesbians and gay men showed no sex difference regardless of whether the infidelity was opposite-sex or same-sex.     

Detecting meaning in RSVP at 13 ms per picture

The visual system is exquisitely adapted to the task of extracting conceptual information from visual input with every new eye fixation, three or four times a second. Here we assess the minimum viewing time needed for visual comprehension, using rapid serial visual presentation (RSVP) of a series of six or 12 pictures presented at between 13 and 80 ms per picture, with no interstimulus interval. Participants were to detect a picture specified by a name (e.g., smiling couple) that was given just before or immediately after the sequence. Detection improved with increasing duration and was better when the name was presented before the sequence, but performance was significantly above chance at all durations, whether the target was named before or only after the sequence. The results are consistent with feedforward models, in which an initial wave of neural activity through the ventral stream is sufficient to allow identification of a complex visual stimulus in a single forward pass. Although we discuss other explanations, the results suggest that neither reentrant processing from higher to lower levels nor advance information about the stimulus is necessary for the conscious detection of rapidly presented, complex visual information.     

The binding pool: A model of shared neural resources for distinct items in visual working memory

Visual working memory (VWM) refers to the ability to encode, store, and retrieve visual information. The two prevailing theories that describe VWM assume that information is stored either in discrete slots or within a shared pool of resources. However, there is not yet a good understanding of the neural mechanisms that would underlie such theories. To address this gap, we provide a computationally realized neural account that uses a pool of shared neurons to store information about one or more distinct stimuli. The binding pool model is a neural network that is essentially a hybrid of the slot and resource theories. It describes how information can be stored and retrieved from a pool of shared resources using a type/token architecture (Bowman & Wyble in Psychological Review 114(1), 38–70, 2007; Kanwisher in Cognition 27, 117–143, 1987; Mozer in Journal of Experimental Psychology: Human Perception and Performance 15(2), 287–303, 1989). The model can store multiple distinct objects, each containing binding links to one or more features. The binding links are stored in a pool of shared resources and, thus, produce mutual interference as memory load increases. Given a cue, the model retrieves a specific object and then reconstructs other features bound to that object, along with a confidence metric. The model can simulate data from continuous report and change detection paradigms and generates testable predictions about the interaction of report accuracy, confidence, and stimulus similarity. The testing of such predictions will help to identify the boundaries of shared resource theories, thereby providing insight into the roles of ensembles and context in explaining our ability to remember visual information.     

I Cannot Afford to Have a Life: Employee Adaptation to Feelings of Job Insecurity

This study examines the links between employee perceptions of job insecurity, the work–nonwork interface, and stress‐related outcomes. Drawing on an adaptation perspective, we expect employees feeling greater job insecurity to engage in adaptive work behaviors including less use of work–nonwork support programs and greater willingness to let work permeate into one's personal life, which in turn will associate with greater work–nonwork conflict and emotional exhaustion. Data were collected from employees within a large energy company at 2 points in time. Results support the model, offering important insights into employee behavioral responses to job insecurity and key mechanisms through which insecurity may foster diminished employee well‐being.
