Capacity limitations in human information processing

The nature of processing demands during a letter-match task was investigated in an extension of the Posner and Boies (1971) paradigm. In Experiment I, a visual probe was employed in addition to an auditory probe in two different experimental conditions. The shape of the auditory probe reaction time (RT) function was similar to that found by Posner and Boies. However, in contrast to their findings, RT was greatly increased shortly after presentation of the first letter for the visual probe function. It was concluded that perceptual as well as postperceptual limitations on processing capacity exist. A second experiment provided further support for this hypothesis.     

Effectiveness of Imagery Rehearsal Therapy for the Treatment of Combat-Related Nightmares in Veterans

Imagery Rehearsal Therapy (IRT) has been shown to be efficacious in reducing nightmares, but the treatment has not been well-studied in veterans. The effectiveness of IRT was assessed from a chart review of veterans seeking outpatient treatment for chronic, trauma-related nightmares. Of those offered IRT, veterans who completed a full course of treatment for PTSD in the past year were more likely to initiate treatment. However, completion of IRT was not related to previous treatment, demographic variables, or nightmare severity reported at the first treatment session. Treatment completers reported significant reductions in nightmare frequency and intensity, severity of insomnia, and subjective daytime PTSD symptoms. Insomnia and PTSD symptoms, on average, were below clinical cutoffs following treatment, and 23% of patients showed a complete treatment response (≤ 1 nightmare/week). Findings suggest IRT may be an effective short-term treatment for nighttime and daytime PTSD symptoms among veterans who complete a full course of treatment.     

Relational knowledge: the foundation of higher cognition

Accumulating evidence on the nature, function and acquisition of relational knowledge indicates a crucial role of such knowledge in higher cognitive processes. In this review, we specify the essential properties of relational knowledge, together with the role it plays in reasoning, categorisation, planning, quantification and language. Furthermore, we discuss the processes involved in its acquisition and how these processes have been implemented in contemporary neural network models. We present evidence demonstrating that relational knowledge integrates heuristic and analytic cognition, is important for symbolic processes and the creation of novelty, activates specific regions of the prefrontal cortex, and is the most recently evolved and slowest-developing cognitive process. Arguably, relational knowledge represents the core of higher cognition.     

For God (or) country: the hydraulic relation between government instability and belief in religious sources of control

It has been recently proposed that people can flexibly rely on sources of control that are both internal and external to the self to satisfy the need to believe that their world is under control (i.e., that events do not unfold randomly or haphazardly). Consistent with this, past research demonstrates that, when personal control is threatened, people defend external systems of control, such as God and government. This theoretical perspective also suggests that belief in God and support for governmental systems, although seemingly disparate, will exhibit a hydraulic relationship with one another. Using both experimental and longitudinal designs in Eastern and Western cultures, the authors demonstrate that experimental manipulations or naturally occurring events (e.g., electoral instability) that lower faith in one of these external systems (e.g., the government) lead to subsequent increases in faith in the other (e.g., God). In addition, mediation and moderation analyses suggest that specific concerns with order and structure underlie these hydraulic effects. Implications for the psychological, sociocultural, and sociopolitical underpinnings of religious faith, as well as system justification theory, are discussed.     

Expressed emotion and sociocultural moderation in the course of schizophrenia

This study examined whether the sociocultural context moderates the relationship between families' expressed emotion (EE) and clinical outcomes in schizophrenia. In a sample of 60 Mexican American caregivers and their ill relatives, we first assessed whether EE and its indices (criticism, emotional overinvolvement [EOI], and warmth) related to relapse. Second, we extended the analysis of EE and its indices to a longitudinal assessment of symptomatology. Last, we tested whether bidimensional acculturation moderated the relationship between EE (and its indices) and both relapse and symptom trajectory over time. Results indicated that EOI was associated with increased relapse and that criticism was associated with increased symptomatology. Additionally, as patients' Mexican enculturation (Spanish language and media involvement) decreased, EE was increasingly related to relapse. For symptomatology, as patients' U.S. acculturation (English language and media involvement) increased, EE was associated with increased symptoms longitudinally. Our results replicate and extend past research on how culture might shape the way family factors relate to the course of schizophrenia.     

Fairness lies in the heart of the beholder: How the social emotions of third parties influence reactions to injustice

The present research explores third parties’ (e.g., jurors, ombudsmen, auditors, and employees observing others’ encounters) ability to objectively judge fairness. More specifically, the current research suggests that third parties’ justice judgments and reactions are biased by their attitudes toward the decision recipient and, in particular, the affective aspect of those attitudes as characterized by their felt social emotions. We explore how the congruence of a social emotion (i.e., the extent to which the emotion reflects feeling a subjective sense of alignment with the target of the emotion) can influence their evaluations of recipients’ decision outcomes. The five studies presented show that congruence can lead third parties to react positively to objectively unfair decision outcomes and, importantly, that the influence of social emotions on subjective justice judgments drive third party reactions to decisions, decision makers, and even national policies.     

Children's utilization of emotion expectancies in moral decision‐making

This study investigated the relevance of emotion expectancies for children's moral decision‐making. The sample included 131 participants from three different grade levels (M = 8.39 years, SD = 2.45, range 4.58–12.42). Participants were presented a set of scenarios that described various emotional outcomes of (im)moral actions and asked to decide what they would do if they were in the protagonists' shoes. Overall, it was found that the anticipation of moral emotions predicted an increased likelihood of moral choices in antisocial and prosocial contexts. In younger children, anticipated moral emotions predicted moral choice for prosocial actions, but not for antisocial actions. Older children showed evidence for the utilization of anticipated emotions in both prosocial and antisocial behaviours. Moreover, for older children, the decision to act prosocially was less likely in the presence of non‐moral emotions. Findings suggest that the impact of emotion expectancies on children's moral decision‐making increases with age. Contrary to happy victimizer research, the study does not support the notion that young children use moral emotion expectancies for moral decision‐making in the context of antisocial actions.
