Interpersonal Violence,Depression, and Executive Function

This study considers links between the number of types of violence to which women have been exposed, depression, and executive functions (EFs). Substantial research has established EF deficits among depressed individuals as well as individuals exposed to trauma. Studies have also indicated a relationship between trauma exposure and depressive symptoms across a range of traumatic events, such as combat exposure, motor vehicle accidents, natural disasters, and assaults. This study examines this relationship in an ethnically diverse community sample of 93 women exposed to interpersonal violence who completed a battery of EF tasks that assessed processing speed, working memory, response inhibition, and set shifting. Women reported an average of 5.8 types of interpersonal violence events. The number of types of interpersonal violence events was significantly related to depressive symptoms, although not EF performance. Specific EFs, such as working memory and response inhibition, were positively related to depressive symptoms.     

Trauma Exposure and Health: A Review of Outcomes and Pathways

A growing body of literature has established robust relations between trauma and a variety of adverse physical health outcomes. In both retrospective and prospective research, adults with a history of self-reported or court-substantiated maltreatment report significantly more health concerns than those without maltreatment histories, in both clinical and community samples, whether health problems are self-reported or physician-diagnosed. Two pathways by which poor health outcomes are theorized to occur include the biological pathway, which largely implicates severe stress and subsequent dysregulations in central stress-response systems as the underlying cause of health problems, and the behavioral pathway, which suggests that health risk behaviors are largely responsible for the relations between trauma and health. This article reviews the research evaluating the relations between various types of trauma, particularly physical and sexual abuse in childhood, and three such health outcomes: pain, gastrointestinal disorders, and cardiovascular disease. Evidence to support the biological and behavioral pathways is also reviewed.     

Childhood Maltreatment Increases the Risk of Intimate Partner Violence via PTSD and Anger Personality Traits in Individuals Consulting for Sexual Problems

Childhood maltreatment is a significant risk factor for the perpetration of intimate partner violence (IPV) in adulthood. This study tested, in a clinical sample, a conceptual model suggesting that childhood maltreatment contributes to the development of anger personality traits, directly and indirectly via posttraumatic stress disorder (PTSD), and that anger personality traits, in turn, are associated with IPV. Adults consulting for sex therapy (n = 114) completed self-report measures of childhood maltreatment, PTSD, anger, and IPV. Participants were exposed to high rates of childhood maltreatment (83%). Path analysis supported the hypothesized model: Exposure to child maltreatment was associated with anger personality traits, and this association was partially mediated by PTSD symptoms. Anger personality traits were highly correlated with IPV.     

Getting one step closer to deduction: Introducing an alternative paradigm for transitive inference

Transitive inference is claimed to be “deductive”. Yet every group/species ever reported apparently uses it. We asked 58 adults to solve five-term transitive tasks, requiring neither training nor premise learning. A computer-based procedure ensured all premises were continually visible. Response accuracy and RT (non-discriminative nRT) were measured as is typically done. We also measured RT confined to correct responses (cRT). Overall, very few typical transitive phenomena emerged. The symbolic distance effect never extended to premise recall and was not at all evident for nRT; suggesting the use of non-deductive end-anchor strategies. For overall performance, and particularly the critical B?D inference, our findings indicate that deductive transitive inference is far more intellectually challenging than previously thought. Contrasts of our present findings against previous findings suggest at least two distinct transitive inference modes, with most research and most computational models to date targeting an associative mode rather than their desired deductive mode. This conclusion fits well with the growing number of theories embracing a “dual process” conception of reasoning. Finally, our differing findings for nRT versus cRT suggest that researchers should give closer consideration to matching the RT measure they use to the particular conception of transitive inference they pre-held.     

The basic components of adult playfulness and their relation with personality: The hierarchical factor structure of seventeen instruments

The primary aim of this study was testing the structure of adult playfulness in a joint analysis of seventeen questionnaires and testing the relation of the factors with the big five personality traits. A sample of 244 adults completed the questionnaires and a five factor-solution fit the data best; i.e., (a) Humorousness; (b) Cheerfulness–Uninhibitedness; (c) Expressiveness; (d) Other-directedness; and (e) Intellectuality–Creativity. Correlation analyses (bivariate, canonical) and regression analyses indicated strong overlap of the broader personality factors and the Cheerfulness–Uninhibitedness-factor (extraversion and emotional stability) as well as the Expressiveness-factor (extraversion). The study contributes towards a better understanding of the structure of playfulness in questionnaires developed for adults. Implications for future research are discussed.     

Feature or location? Infants and adults adopt different strategies to search for a hidden toy in an ambiguous task

Evidence suggests that infants and adults attribute different importance to certain object properties when performing object-directed actions. Namely, infants tend to rely on information about an object's location, whereas adults are more likely to base their actions on its features. In this study, we tested whether the strategic choices of infants (aged 13 months) and adults would be modified by the context of the demonstration. Participants watched as an experimenter hid a ball under one of two different coloured containers, using either a communicative or a non-communicative manner. Then, the locations of the two containers were changed out of sight of the participant. During the test, participants were encouraged to look for the ball under one of the containers. We found that adults were more likely to follow a feature-based strategy than infants. However, there was no effect of the context of the demonstration, suggesting that communication may play different roles in encoding object properties and directing overt behaviour.     

The cost of thinking about false beliefs: evidence from adults' performance on a non-inferential theory of mind task

Much of what we know about other people's beliefs comes non-inferentially from what people tell us. Developmental research suggests that 3-year-olds have difficulty processing such information: they suffer interference from their own knowledge of reality when told about someone's false belief (e.g., [Wellman, H. M., & Bartsch, K. (1988). Young children's reasoning about beliefs. Cognition, 30, 239-277.]). The current studies examined for the first time whether similar interference occurs in adult participants. In two experiments participants read sentences describing the real colour of an object and a man's false belief about the colour of the object, then judged the accuracy of a picture probe depicting either reality or the man's belief. Processing costs for picture probes depicting reality were consistently greater in this false belief condition than in a matched control condition in which the sentences described the real colour of one object and a man's unrelated belief about the colour of another object. A similar pattern was observed for picture probes depicting the man's belief in most cases. Processing costs were not sensitive to the time available for encoding the information presented in the sentences: costs were observed when participants read the sentences at their own pace (Experiment 1) or at a faster or a slower pace (Experiment 2). This suggests that adults' difficulty was not with encoding information about reality and a conflicting false belief, but with holding this information in mind and using it to inform a subsequent judgement.     

Empowering Community Settings: Agents of Individual Development, Community Betterment, and Positive Social Change

The pathways and processes through which empowering community settings influence their members, the surrounding community and the larger society are examined. To generate the proposed pathways and processes, a broad range of studies of community settings were reviewed, in the domains of adult well-being, positive youth development, locality development, and social change. A set of organizational characteristics and associated processes leading to member empowerment across domains were identified, as well as three pathways through which empowering settings in each domain contribute to community betterment and positive social change. The paper concludes with an examination of the ways that community psychology and allied disciplines can help increase the number and range of empowering settings, and enhance the community and societal impact of existing ones.

Event Centrality as Mediator Between Attributions and Mental Health Outcomes

Consistent with the Reformulated Model of Learned Helplessness, attributions that are more internal, stable, and global have been shown to be associated with greater posttraumatic stress and depression symptoms. Even though the Reformulated Model of Learned Helplessness has been revised to clarify that attributions are most likely to lead to adverse outcomes when the event is considered to be important to the person and the outcomes very negative (Hopelessness Model of Depression), most attribution studies do not account for the importance of the event to the individual. The current study examined whether perceptions of event importance mediated the relationship between attributions and posttraumatic stress and depression symptoms in a sample of 313 college students who reported about their worst life event. Consistent with the Hopelessness Model of Depression, results supported the mediational role of event significance. Findings suggest that maladaptive attributions may contribute to symptoms of posttraumatic stress disorder and depression both directly and through the event’s importance to a person’s sense of identity.     

Betrayed? That’s Me: Implicit and Explicit Betrayed Self-Concept in Young Adults Abused as Children

Attenuated awareness of betrayal, or “betrayal blindness,” is a proposed survival mechanism in relationships where awareness of betrayal will mobilize confront-or-withdraw responses that jeopardize a needed relationship. Empirical tests of betrayal blindness and its effects are hampered by the methodological conundrum of how to measure an absence of awareness. The purpose of this study was to evaluate the validity of a novel empirical method to measure implicit betrayed self-concept, the first step in a long-term research aim to operationalize “betrayal blindness.” Informed by betrayal trauma theory, we hypothesized that a history of betrayal within close childhood relationships (but not recent close relationships or “not-close” relationships) would predict implicit betrayed-self associations in young adulthood. An adaptation of the Implicit Association Test (IAT) and measured implicit and explicit betrayed-self associations and self-reported history of physical, sexual, and psychological abuse in 529 university undergraduates was designed. Internal consistency reliability of the betrayed self IAT was low but adequate. Hierarchical regression modeling revealed that history of abuse within close childhood relationships (but not recent close relationships or “not-close” relationships) predicted betrayed-self IAT scores. The effect size was small, β = .12, p < .05, 95% CI [.01, .07], R² = .12. In addition, history of betrayal by someone close (but not someone “not close”) at any age predicted increased explicit evaluations of the self as betrayed versus respected, a small effect size, R² = .16. Findings indicate that implicit betrayed self-concept can be measured empirically.
