Sex differences in the assignment of responsibility for an accident

Two experiments examined the proposition that females assign less responsibility than males to a perpetrator in a feminine occupation and males assign less responsibility than females to a perpetrator in a masculine occupation. The results from Experiment 1 indicated that females assigned less responsibility than males to a perpetrator in a feminine occupation, whereas males and females assigned equal responsibility to a perpetrator in a masculine occupation. These results did not generalize to measures of causality, foreseeability, intent, or justification. Therefore, they suggest that responsibility may have been assigned on the basis of reliability of the perpetrator's behavior and that a measure of reliability may be more appropriate than a measure of responsibility. The results from Experiment 2 supported the contention. Females judged the behavior of a perpetrator in a feminine occupation to be more reliable than did males, and males judged the behavior of a perpetrator in a masculine occupation to be more reliable than did females.     

Introduction to the Special Section: Toward Implementing Physiological Measures in Clinical Assessments of Adult Mental Health

This article serves as the introduction to the Special Section called “Toward Implementing Physiological Measures in Clinical Assessments of Adult Mental Health.” As such, it provides an overview of the importance of integrating assessments of physiological and subjective processes in mental health assessments and discusses the Research Domain Criteria (RDoC) initiative. In addition, it summarizes the findings from the four empirical studies published in the Special Section. Collectively, these studies sought to illustrate how physiological assessments can be incorporated in mental health assessments conducted in applied research and clinic settings. In all, we hope that this Special Section will inspire the type of interdisciplinary research spanning basic and applied work that will be critical to advancing the RDoC initiative.     

Kea cooperate better with sharing affiliates

Controlled studies that focus on intraspecific cooperation tasks have revealed striking similarities, but also differences, in abilities across taxa as diverse as primates, fish, and birds. Such comparisons may provide insight into the specific socio-ecological selection pressures that led to the evolution of cooperation. Unfortunately, however, compared to primates data on birds remain relatively scarce. We tested a New Zealand psittaciform, the kea, in a dyadic cooperation task using the loose-string design. During trials our subjects were in separate compartments, but obtained a common reward that could be divided multiple ways, allowing the examination of reward division effects. Ten individuals were tested twice in 44 combinations of partners. Dyads with a high affiliation score attempted to cooperate more often and were also more often successful in doing so. Furthermore, dyads that shared rewards more equally seemed to be more likely to attempt cooperation in the next trial. Like other bird and some monkey species, but unlike, for example, chimpanzees, kea did not spontaneously show understanding of either the role of the partner or the mechanism behind the cooperation task. This may point to true disparities between species, but may also be due to differences in task design and/or the amount of exposure to similar tasks and individual skills of the subjects.     

Inducing Knowledgeability From Niceness: Children Use Social Features for Making Epistemic Inferences

In many ways, evaluating informants based on their features is a problem of induction: Children rely on the assumption that observable informant characteristics (e.g., traits, behaviors, social categories) will predict unobservable characteristics (e.g., future behavior, knowledge states, intentions). Yet to make sensible inferences, children must recognize what informant features are relevant for what types of inferences. The current research investigated whether preschoolers use social features (e.g., niceness) for making epistemic inferences and, conversely, whether they use intellectual features (e.g., expertise) for making social inferences. In the study, 96 preschoolers (M_age = 4.96 years) were asked to attribute knowledge and behaviors to a mean informant, a nice informant, and a neutral informant. Between subjects, we varied which informant had expertise. We found that when attributing knowledge, children used both features: attributing more knowledge to nicer informants, but also attributing more knowledge to an informant when he had expertise. In contrast, when making social inferences, children relied primarily on social features.     

Premonitory urges are associated with decreased grey matter thickness within the insula and sensorimotor cortex in young people with Tourette syndrome

Tourette syndrome (TS) is a neurological disorder characterized by vocal and motor tics and is associated with cortical–striatal–thalamic–cortical circuit (CSTC) dysfunction and hyperexcitability of cortical limbic and motor regions, which are thought to lead to the occurrence of tics. Importantly, individuals with TS often report that their tics are preceded by ‘premonitory sensory phenomena’ (PSP) that are described as uncomfortable cognitive or bodily sensations that precede the execution of a tic, and are experienced as a strong urge for motor discharge. While the precise role played by PSP in the occurrence of tics is controversial, PSP are nonetheless of considerable theoretical and clinical importance in TS, not least because they form the core component in many of the behavioural therapies that are currently used in the treatment of tic disorders. In this study, we investigated the brain structure correlates of PSP. Specifically, we conducted a whole‐brain analysis of cortical (grey matter) thickness in 29 children and young adults with TS and investigated the association between grey matter thickness and PSP. We demonstrate for the first time that PSP are inversely associated with grey matter thickness measurements within the insula and sensorimotor cortex. We also demonstrate that grey matter thickness is significantly reduced in these areas in individuals with TS relative to a closely age‐ and gender‐matched group of typically developing individuals and that PSP ratings are significantly correlated with tic severity.     

The effect of visualization on visual search performance

Striking results recently demonstrated that visualizing search for a target can facilitate visual search for that target on subsequent trials (Reinhart et al. 2015). This visualization benefit was even greater than the benefit of actually repeating search for the target. We registered a close replication and generalization of the original experiment. Our results show clear benefits of repeatedly searching for the same target, but we found no benefit associated with visualization. The difficulty of the search task and the ability to monitor compliance with instructions to visualize are both possible explanations for the failure to replicate, and both should be carefully considered in future research exploring this interesting phenomenon.     

The Power of Perception: Toward a Model of Cultural Oppression and Liberation

Oppression is defined and identified as the basis of a considerable range of psychopathology. An exploratory transcultural model of counseling based on oppression is introduced with the goal of serving both oppressed and oppressive clients. Perception, as perspicacity, is the key to this exploratory model. The authors suggest that oppressed persons generally possess a considerable degree of perception of their oppressors even though they may be unaware of it. Research from the literature on depressive realism is used to infer support. Counseling approaches to oppressed persons are introduced including a new approach to cognitive therapy and an emphasis on liberation rather than adjustment. Counseling approaches to oppressors are also discussed based on the rehabilitation of empathy and perception.     

Combining propensity score matching and group-based trajectory analysis in an observational study

In a nonrandomized or observational study, propensity scores may be used to balance observed covariates and trajectory groups may be used to control baseline or pretreatment measures of outcome. The trajectory groups also aid in characterizing classes of subjects for whom no good matches are available and to define substantively interesting groups between which treatment effects may vary. These and related methods are illustrated using data from a Montreal-based study. The effects on subsequent violence of gang joining at age 14 are studied while controlling for measured characteristics of boys prior to age 14. The boys are divided into trajectory groups based on violence from ages 11 to 13. Within trajectory group, joiners are optimally matched to a variable number of controls using propensity scores, Mahalanobis distances, and a combinatorial optimization algorithm. Use of variable ratio matching results in greater efficiency than pair matching and also greater bias reduction than matching at a fixed ratio. The possible impact of failing to adjust for an important but unmeasured covariate is examined using sensitivity analysis.     

Finding the Right Value: Framing Effects on Domain Experts

By defining the essence of a policy problem, an issue frame shapes how individuals think about a political issue. In this research, we investigate framing effects among domain experts, an understudied yet increasingly important set of individuals in the policymaking process. Because domain experts have extensive and highly structured knowledge on a particular topic, they are likely to actively process issue frames to which they are exposed. Consequently, we hypothesize that frames consistent with experts' values will be particularly influential, whereas frames inconsistent with their values will lead to contrast effects. We test our hypotheses on a unique set of domain experts by examining professional farmers' attitudes toward no‐till agriculture. Using an experimental design, we find evidence that environmental values interact with frames to influence farmers' interest in no‐till, especially when farmers are exposed to a novel frame.     

Vygotsky and beyond: horizons for the future of psychology / Vygotski y más allá: horizontes para el futuro de la psicología

In this article some usually overlooked aspects of Vygotsky’s work are presented. First, the understanding of the mediation system as a trans-organic, extended branch of the psychological system. Second, the semantic nature of conscience and the systemic neuropsychological organization of higher functions. Third, the leading role played in the psychic system by directive functions. Fourth, the understanding of human evolution as open and permanently provisional. Last, a reference is made to the role of psychology in the process of human auto-evolution, which Vygotsky viewed as a mission.
