Cognitive outcomes of pediatric stroke

A limited number of longitudinal studies have investigated long-term neuropsychological development in the pediatric stroke population. This study retrospectively examines cognitive outcomes in 41 children with a history of stroke, with reference to age at stroke, laterality, region and mechanism of stroke. In the course of recovery, neuropsychological measures of intellectual functioning and memory were administered at two time points, whilst executive functioning, attention and academic skills were administered at one time point. As predicted, children with stroke performed significantly worse compared to normative expectations on all neuropsychological measures. Up to two thirds of children scored in the borderline impaired and impaired ranges on at least one domain of cognition. Performance on intellectual and memory assessment remained relatively stable over time. Younger age at stroke was found to be associated with poorer intellectual functioning. No effects of laterality of stroke on neuropsychological performance over time were found. Children with subcortical stroke demonstrated a greater improvement in immediate memory over time than children with cortical stroke. These findings reveal that children with stroke display long-term cognitive difficulties that typically remain stable over time. Attention and academic skills are particularly vulnerable to impairment. Further evidence that age at stroke is a significant factor in terms of cognitive outcome is provided, in support of the “early vulnerability” position.     

Gender stereotype–consistent memories: How system justification motivation distorts the recollection of information related to the self

Research based on system justification theory has shown that women’s self-perceptions may be altered by the motivation to justify the system and its inequalities. Self-perceptions being built on past experiences, the present study aimed to explore how system justification motivation induced through a system dependency manipulation may alter both women’s recall of autobiographical memories and their behavior. Women who were led to feel highly dependent on the social system perceived themselves as more competent and recalled memories of higher competence in the verbal domain compared with the negatively stereotyped scientific domain. Women’s behavioral choices (between doing a verbal or a math exercise) also revealed a higher preference for the gender stereotype–consistent verbal exercise in the high–system dependency condition, as compared with the low–system dependency condition. These results suggest that gender stereotypes may not only satisfy self- or group-serving motivation but also the need to perceive the system in a positive light.     

当事人的投入与会谈效果、咨询效果的关系研究

本研究探索了当事人会谈时的投入与即时会谈效果的关系;当事人咨询初期的投入与整体咨询效果的关系。结果发现当事人会谈时的投入与即时会谈效果、在咨询初期的投入与整体咨询效果都呈现显著的正相关。进一步回归分析发现,当事人在咨询初期的投入与整体咨询效果呈现正U型的偏态分布,少数投入水平最低的当事人获得中等水平的咨询效果,中等投入水平的当事人咨询效果最差,投入水平最高的当事人的咨询效果最好。     

Nameless + harmless = blameless: When seemingly irrelevant factors influence judgment of (un)ethical behavior

People often make judgments about the ethicality of others’ behaviors and then decide how harshly to punish such behaviors. When they make these judgments and decisions, sometimes the victims of the unethical behavior are identifiable, and sometimes they are not. In addition, in our uncertain world, sometimes an unethical action causes harm, and sometimes it does not. We argue that a rational assessment of ethicality should not depend on the identifiability of the victim of wrongdoing or the actual harm caused if the judge and the decision maker have the same information. Yet in five laboratory studies, we show that these factors have a systematic effect on how people judge the ethicality of the perpetrator of an unethical action. Our studies show that people judge behavior as more unethical when: (1) identifiable vs. unidentifiable victims are involved and (2) the behavior leads to a negative rather than a positive outcome. We also find that people’s willingness to punish wrongdoers is consistent with their judgments, and we offer preliminary evidence on how to reduce these biases.     

Brief anger interventions with offenders may be ineffective: A replication and extension

Anger-management interventions are widely delivered in the criminal justice and forensic mental health systems. Whilst previous research has generally supported the thesis that anger management is an effective intervention for anger problems in general there remains a need to determine its effectiveness with offender populations. This paper reports the results of a controlled outcome study of a 20 h anger-management program offered to offenders. Those receiving treatment showed improvements in their knowledge about anger, but showed little change on measures of anger and anger expression when compared to waiting-list controls. Scores on measures of treatment readiness and level of need for treatment were however, correlated with post-treatment improvement. These findings are discussed in terms of their implications for the assessment and selection of appropriate participants for offender anger-management programs.     

The effect of company recruitment web site orientation on individuals’ perceptions of organizational attractiveness

The use of company web pages to attract prospective job applicants has experienced tremendous growth in recent years. To date, very little is known about the process by which recruitment web sites influence individuals’ desire to pursue employment with an organization. This study attempts to address this issue by using an experimental design to investigate the relationships among recruitment web site orientation, individuals’ expectations concerning the use of Internet technology, web site usability, and organizational attractiveness. Survey results from 252 business students indicated that web site orientation and outcome expectancy influenced organizational attractiveness perceptions through influencing the perceived usability of the website. The implications of such results for firms interested in using recruitment web sites to attract applicants are discussed.     

Does a smartphone on the desk drain our brain? No evidence of cognitive costs due to smartphone presence in a short-term and prospective memory task

It has recently been shown that the mere presence of one’s own smartphone on the desk impairs working memory performance. The aim of this study was to follow up on this important finding by assessing the effect of smartphone presence (present on the desk vs. absent from the desk) on different memory functions (short-term memory and prospective memory), and by further examining the moderating role of individual differences in smartphone dependency and impulsiveness. We found no overall effect of smartphone presence on short-term and prospective memory performance. There was a moderating effect for prospective memory: Performance was better when the smartphone was absent versus present for participants with low smartphone dependency. In light of the absence of an overall effect of smartphone presence on memory functions, our results show that previous findings of impairments in working memory due to smartphone presence do not generalize to other domains of memory capacity.     

Outcome processing and the sense of agency

People can distinguish outcomes they cause from those they do not; that is, they are quite able to sense self-agency in outcomes. A well-received idea is that the sense of agency is produced by a comparison between a predicted outcome and the actual outcome that occurs. While research has generally focused on understanding predictive representations and the comparison process, less work has been done on the actual outcomes and, in particular, how these are perceived or apprehended. Here, we studied this issue. In two experiments, we found outcomes are continuously, as opposed to partially, sampled throughout their span. Specifically, we found that prediction-inconsistent signals embedded within otherwise prediction-consistent outcomes were able to influence agency ratings, and this was true whether the contrary signals were embedded early or late in the outcome.
