幼儿心理理论表现的任务特异性分析

研究以90名3～5岁幼儿为被试,采用相同材料和标准评估幼儿外表-事实的区分和错误信念认识,考察幼儿表现的任务特异性及材料刺激的影响。结果表明;幼儿的表现仍存在任务特异性,并且实验材料对儿童的外表-事实区分和错误信念认识具有重要影响。在解释这些结果时,特殊领域知识习得观似乎优于表征缺失理论。     

Effects of the good behavior game across classroom contexts

The Good Behavior Game (GBG), a well‐researched classroom group contingency, is typically played for brief periods of time, which raises questions about the effects on subsequent contexts. This study used a multiple baseline design and showed that when the GBG was implemented in one context, behavior improved in only that context. Behavior improved in the subsequent activity only when the GBG was implemented.     

Teaching complex verbal operants to children with autism and establishing generalization using the peak curriculum

The present study evaluated the feasibility of the PEAK Relational Training System's Generalization Module (Dixon, 2014b) to teach and establish generalization of autoclitic mands, distorted tacts, and creative path finding in three children diagnosed with autism spectrum disorder. Using a multiple‐baseline design across behaviors, each participant was provided with differential reinforcement and a least‐to‐most prompting hierarchy for correct responses to a subset of stimuli, and responses to other similar stimulus sets were probed for emergent generalization. Following training, each participant successfully acquired the directly trained behaviors and demonstrated generalization to the nonreinforced test exemplars. These data support the utility of Skinner's (1957) analysis to teach complex forms of verbal operants, and suggest that a manualized curriculum such as PEAK may have utility for promoting skill development and generalization for front line staff and caregivers of children with autism.     

Aerobic Fitness Is Associated With Cognitive Control Strategy in Preadolescent Children

The authors used a conditional accuracy function (CAF) method to compute the mean accuracy of multiple reaction time ranges, to investigate the association between aerobic fitness and the utilization of cognitive control strategy during preadolescence. Thirty-eight higher- and lower-fit children were grouped according to their cardiorespiratory capacity (VO_2max) and completed a modified flanker task. Seventeen young adults were recruited as a reference group of maturation. The results showed that higher-fit children exhibited an adult-like performance pattern, and demonstrated increased overall response accuracy compared to lower-fit children, with a disproportionally larger increase in individual responses when the time allowed for discriminative processing was constrained. These findings suggest that aerobic fitness is associated with enhanced cognitive control and development of a more proactive control strategy during flanker task in preadolescent children.     

Working Memory Training Improves Dual-Task Performance on Motor Tasks

The authors investigated whether working memory training improves motor-motor dual-task performance consisted of upper and lower limb tasks. The upper limb task was a simple reaction task and the lower limb task was an isometric knee extension task. 45 participants (age = 21.8 ± 1.6 years) were classified into a working memory training group (WM-TRG), dual-task training group, or control group. The training duration was 2 weeks (15 min, 4 times/week). Our results indicated that working memory capacity increased significantly only in the WM-TRG. Dual-task performance improved in the WM-TRG and dual-task training group. Our study provides the novel insight that working memory training improves dual-task performance without specific training on the target motor task.     

The personality-related implications of Stroop performance: Stress-contingent self-control in daily life

People with higher levels of executive control, relative to low levels, should be more capable of responding to the problems and stressors of their lives, yet we know very little concerning this lab-to-life interface. Two studies (total N = 254) sought to speak to questions of this type using the Stroop task, a classic measure of executive control. Individual differences in Stroop costs were assessed in the laboratory, following which the same people completed daily diary protocols for two weeks. Consistent with neurocognitive theories of executive control, both studies found that people capable of overriding the Stroop effect tended to recruit self-control in response to the stressful circumstances of their lives. By contrast, people with high Stroop costs did not exhibit this problem-focused form of recruitment. The findings extend our knowledge of individual differences in executive control and the manner in which they operate in daily life.     

Selective attention to emotional prosody in social anxiety: a dichotic listening study

The majority of evidence on social anxiety (SA)-linked attentional biases to threat comes from research using facial expressions. Emotions are, however, communicated through other channels, such as voice. Despite its importance in the interpretation of social cues, emotional prosody processing in SA has been barely explored. This study investigated whether SA is associated with enhanced processing of task-irrelevant angry prosody. Fifty-three participants with high and low SA performed a dichotic listening task in which pairs of male/female voices were presented, one to each ear, with either the same or different prosody (neutral or angry). Participants were instructed to focus on either the left or right ear and to identify the speaker’s gender in the attended side. Our main results show that, once attended, task-irrelevant angry prosody elicits greater interference than does neutral prosody. Surprisingly, high socially anxious participants were less prone to distraction from attended-angry (compared to attended-neutral) prosody than were low socially anxious individuals. These findings emphasise the importance of examining SA-related biases across modalities.     

义符启动范式下家族大小和类别一致性对义符语义激活的影响

采用义符启动范式,考察不同加工深度任务中家族大小和类别一致性对义符语义激活的影响。结果发现:在词汇判断中,家族大小影响义符的语义激活,大家族义符的语义不容易激活,小家族义符的语义容易激活。在语义相关判断中,类别一致性影响义符的语义激活,类别一致性高的义符的语义容易激活,并且在错误率上,这一影响受义符的家族大小调节。义符类别一致性影响义符家族效应的作用方向:当类别一致性低时,出现抑制的家族效应;当类别一致性高时,家族效应无影响或表现为促进作用。     

规则适应视角下辱虐管理的成因机制

基于规则适应及资源依赖理论的解释视角,本研究考察了下属工作绩效与政治技能对上级辱虐的影响。通过对采集自两家企业的243对领导-下属的配对问卷进行分析,本研究的多项式回归与响应面分析表明,当下属的工作绩效(遵循做事显规则)与政治技能(遵循做人潜规则)在较高水平上保持一致时,其遭受的上级辱虐最少。但这种较高水平的一致只能维持在特定范围内,当两者过高时,反而易遭致上级的辱虐行为。同时,在工作绩效与政治技能存在差异的情境下,相比于"高工作绩效,低政治技能"的下属,"低工作绩效,高政治技能"的下属遭受的上级辱虐要更少。文章分析并证明了遵循不同规则的下属会导致不同程度的上级辱虐。     

不同任务类型对熟练维汉双语者跨语言启动不对称性的影响

采用两种不同的任务类型对熟练维汉双语者跨语言掩蔽翻译启动效应进行考察,结果发现,在词汇决定任务中,熟练维汉双语者在L1-L2和L2-L1两个方向上均表现出了掩蔽翻译启动效应,但L1-L2方向远大于L2-L1方向,即掩蔽翻译启动效应具有不对称性。而在语义分类任务中,熟练维汉双语者在两个方向上表现出的翻译启动效应量相近,具有对称性。结果支持Kroll的修正层级模型。
