Evaluation of a Spanish version of the Buss and Perry aggression questionnaire: Some personal and situational factors related to the aggression scores of young subjects

The psychometric properties of a Spanish translation of the Buss and Perry aggression questionnaire adapted for pre-adolescents and adolescents have been studied. A maximum-likelihood confirmatory factor analysis corroborates Buss and Perry’s four-factor structure. The internal consistency of each factor and of the total score has proved to be satisfactory. The four factors are more closely interrelated in pre-adolescents than in adolescents.A second aim of this work has been to further our understanding of the possible relationship between aggression scores and certain outside-school activities of the subjects studied. Two thousand two hundred and eight students filled in the questionnaire together with a self-report concerning their habits. The results show that the aggression scores rise concomitantly with time spent watching television and playing video games and decrease the greater the time devoted to extra-curricular reading or moderate amounts of homework. Statistically significant differences relating to age and gender were also found.     

A cross-syndrome study of the development of holistic face recognition in children with autism, Down syndrome, and Williams syndrome

We report a cross-syndrome comparison of the development of holistic processing in face recognition in school-aged children with developmental disorders: autism, Down syndrome, and Williams syndrome. The autism group was split into two groups: one with high-functioning children and one with low-functioning children. The latter group has rarely been studied in this context. The four disorder groups were compared with typically developing children. Cross-sectional trajectory analyses were used to compare development in a modified version of Tanaka and Farah’s part–whole task. Trajectories were constructed linking part–whole performance either to chronological age or to several measures of mental age (receptive vocabulary, visuospatial construction, and the Benton Facial Recognition Test). In addition to variable delays in onset and rate of development, we found an atypical profile in all disorder groups. These profiles were atypical in different ways, indicating multiple pathways to, and variable outcomes in, the development of face recognition. We discuss the implications for theories of face recognition in both atypical and typical development, including the idea that part–whole and rotation manipulations may tap different aspects of holistic and/or configural processing.     

Gender differences in creative thinking revisited: Findings from analysis of variability

This study investigated gender differences in creativity among 985 schoolchildren (499 boys, 486 girls) by analyzing both means and variability. A relatively new creativity test, the Test for Creative Thinking-Drawing Production (TCT-DP), was employed to gain a more refined understanding of gender differences in creativity using a gestalt approach. Whereas the results of analyses of means generally supported the Gender Similarities Hypothesis, the variability analyses tended to support the Greater Male Variability Hypothesis and the Gender Difference Hypothesis. Analyses of the TCT-DP subscales revealed that both genders have their relative strengths and weaknesses in creative thinking. Whereas girls outperformed boys in thoroughness of thinking, boys outperformed girls in boundary-breaking thinking. Variability analyses further showed that more boys clustered in the two extremes of the composite score. Significantly greater variability was found for males on five criteria of the TCT-DP. The educational implications of such a complex pattern of gender differences are discussed. With a view to searching for an explanation for gender differences, several lines of further research are proposed.     

认知加工速度研究中常用的实验和统计方法

认知加工速度理论是解释年龄与认知老年化现象的理论之一,也是近年来心理学研究中的热点之一.该文从理论要点、实验设计、指标选择和统计分析手段四个方面对认知加工速度的研究进行了回顾.在阐述理论要点的基础上,介绍了常用的实验指标和选择指标的标准,以及一些常用的统计分析手段.作者认为除了深入理解理论之外,谨慎地设计实验方案、选择适当的实验指标,以及采用恰当的统计手段都是研究得以顺利进行的必要保障.     

EPQ信度概化的跨文化比较及其启示

对中国7种主要的心理学杂志,于1998-2008年间发表的与EPQ有关的研究报告或论文做信度概化分析,并与Caruso等人对其他国家的EPQ信度概化分析结果作比较。分析结果表明：中外心理量表使用者都存在严重的“信度引入”的状况;分量表的分数的标准差是信度系数最重要的预测变量;但其他预测变量有所不同。提供的启示是：使用心理量表时一定要报告当前样本的信度系数;不符合心理量表特性要求而增加项目,不一定能提高测验结果的信度。     

Adventitious control by the location of comparison stimuli in conditional discriminations.

In a conditional discrimination procedure, samples appeared in a center key, and comparisons appeared in two of four outer keys. The location of comparison keys varied from trial to trial. Separate learning curves for each of the six possible pairs of comparison keys were plotted in a signal-detection space, revealing different patterns of progress on each pair. Also, when learned conditional discriminations were disrupted, pairs of keys differed in their patterns of disruption. Varying the location of comparison stimuli among six different pairs of keys had not eliminated key position as a controlling aspect of the stimuli. The variations simply increased the number of stimulus compounds--key position and experimental stimuli--that the subject learned. Plotting conditional-discrimination learning curves in a signal-detection space reveals relations among hits, false alarms, accuracy, and comparison preference that help to define a subject's progress.     

ROC analyses in eyewitness identification research

There has been a recent surge of interest in analyzing the results of eyewitness identification experiments using Receiver Operating Characteristic (ROC) curves. Proponents of this approach have argued not only that ROC analyses are useful but that more traditional approaches are deficient and should not be used. Three arguments might be made for why researchers would prefer ROC approaches over other techniques. The first is that ROC analyses can provide an index of underlying memory discriminability. The second is that ROC analyses provide useful information about the practical utility of identification procedures. The third is that ROC analyses are useful for testing theory. In this article, I critically examine each of these arguments and conclude that recent claims that ROC methods provide the only justifiable method of comparing identification procedures are overstated.
