Recognition of nonverbal affect and schizotypy

The authors assessed the degree to which schizotypal characteristics in a nonclinical population were associated with impairments in the ability to correctly identify emotions as expressed in facial, paralinguistic, and postural cues. Participants completed the Schizotypal Personality Questionnaire (SPQ; A. Raine, 2005), and the 3 receptive subtests of the Diagnostic Analysis of Nonverbal Accuracy-2 (DANVA2; S. Nowicki Jr., 2005). The SPQ subscales No close friends and Suspiciousness were correlated with impaired ability to correctly identify postural affective cues on the DANVA2. Unusual perceptual experiences were correlated with deficits in the ability to identify emotions on the DANVA2 paralinguistic measure. Impairments in the ability to correctly perceive and respond to expressions of affect may be part of a deficit in social cognition that contributes to development of schizotypal traits.     

A Review of “Suicidal Intent” Within the Existing Suicide Literature

The results of a systematic literature review that investigated suicide intent are presented. Of the 44 relevant articles identified, 17 investigated the relationships between various suicide risk factors and suicide intent and 25 publications investigated the relationships between suicide intent and various suicide outcomes. Despite recent advancements in the definition and nomological validity of suicide intent, a high degree of variability in the empirical measurement and analysis of suicide intent was found. Such variability limits future research related to measuring suicidal risk and outcomes, reporting suicide intent, or the meaningful comparison of diagnostic approaches or treatments across multiple studies.     

Juror Decision‐making in Death Penalty Sentencing when Presented with Defendant's History of Child Abuse or Neglect

Previous studies have found aggravating, mitigating, and null effects of defendant histories of abuse and neglect on punishment preferences in capital sentencing. Perceiving these defendants as more dangerous, jurors may be more likely to favor the death penalty when such evidence is presented. This is counter to the intuition that abuse or neglect reduces culpability, and therefore mitigates the severity of punishment. We investigated the effect of defendant childhood physical abuse, sexual abuse, or neglect on the probability of a prospective juror preferring the death penalty in an between‐subject experimental design. Using vignettes and two large samples (students and jurors), defendant histories were found to mitigate the probability that the hypothetical defendant received the death penalty, with sexual abuse having the most salient effect. Further, the effects were conditioned by preference for the death penalty – larger mitigating effects were observed among individuals who favor the death penalty. These findings suggest that initial judgments of abuse and neglect are related to juror leniency, and further research on the interaction of jury instructions and defendant histories is needed.

Global cognitive function before,surrounding, and after ischemic stroke: the role of risk and protective factors varies with time among ischemic stroke survivors

An estimated 65% of individuals demonstrate multidomain cognitive impairment poststroke, although little is known about the varying role of cognitive risk and protective factors in preischemic, peri-ischemic, and postischemic stroke phases. Longitudinal changes in global cognitive function after ischemic stroke are not well characterized, especially in older adults over age 80. We examined global cognitive function trajectories in these three phases across a mean follow-up of 8.12 (2.30) years in 159 female stroke survivors aged 65–79 at baseline using linear mixed models with change points. In separate models controlling for demographic variables, we tested the interaction of baseline risk and protective factors with stroke phase on global cognitive function. None of the prestroke global cognitive function means or trajectories differed significantly. At the time of ischemic stroke, higher body mass index (BMI), the presence of hypertension (HTN), low optimism, and higher physical function were all associated with significantly greater mean decreases in global cognition (all p’s <.0.0001), but were not significantly different from the contrasting level (all p’s >0.05). Higher BMI, the presence of HTN, low optimism, and higher physical function were in turn protective of global cognitive decline postischemic stroke (all contrasting p values <.01). Baseline factors may play either a risk or a protective role in global cognitive function depending on the phase of ischemic stroke.     

中国人整体性思维特征的情境评估法及其应用

创设了新的中国人思维特征的情境评估方法, 初步应用于整体性思维特征与创造力倾向关系的研究并对其信效度进行了检验。新评估法选取体现典型文化意境和中国人思维特征的成语谜语作为材料, 利用虚拟现实技术构建形与意、情境与语境相互转换的成语谜语文化园, 记录被试游览时即景说出的成语建立成语库, 并编码所录成语的思维特征类型以作为被试的整体性思维测量指标。基于测试数据的信效度分析表明整体性思维成语测试系统信效度表现良好。整体性思维与创造力倾向的相关分析表明, 整体性思维与创造力倾向中的好奇性显著负相关。研究首次证实了利用虚拟现实技术来重建传统文化情境以实现对中国人思维特征的情境评估的可行性, 提示基于虚拟现实技术的情境评估法在未来心理学相关研究中的应用价值。     

群体身份变换性对老年人印象更新的影响：共同内群体认同的中介作用

群体印象更新对于促进群际和谐具有重要的现实意义。本研究采用最简群体再分类范式, 通过4个实验考察了群体身份变换性对老年人外显与内隐印象更新的影响以及共同内群体认同的中介作用。结果发现, 群体身份变换性不仅改变了对最简外群体的印象评价, 而且也提升了年轻人对自然外群体老年人的外显印象评价, 但内隐印象评价的改变不明显; 共同内群体认同在群体身份变换性影响老年人的外显印象更新中起完全中介作用。这些发现不仅从群体身份变换性的视角进一步丰富和拓展了印象更新领域, 而且为群际互动中的偏见消除提供了最简群体再分类新方法。     

Electroencephalogram and heart rate measures of working memory at 5 and 10 months of age

We recorded electroencephalogram (EEG; 6-9 Hz) and heart rate (HR) from infants at 5 and 10 months of age during baseline and performance on the looking A-not-B task of infant working memory (WM). Longitudinal baseline-to-task comparisons revealed WM-related increases in EEG power (all electrodes) and EEG coherence (medial frontal-occipital electrode pairs) at both ages. WM-related decreases in HR were only present at 5 months, and WM-related increases in EEG coherence became more localized by 10 months. Regression analyses revealed that baseline-to-task changes in psychophysiology accounted for variability in WM performance at 10 but not 5 months. HR and EEG power (medial frontal and lateral frontal electrodes) were unique predictors of variability in 10-month WM performance. These findings are discussed in relation to frontal lobe development and represent the first comprehensive longitudinal analysis of age-related changes in the behavioral and psychophysiological correlates of WM.
