Facilitating and inhibiting effects of priming and selection criteria in a sequence of dichotic listening trials

Competing models of attention make different predictions of how priming from recent stimulus processing could interact with intended selection. The present experiment examined the interaction between exogenous attention and endogenous priming across trial sequences. A sound cue directed attention to left, right or both sides before a dichotic syllable pair was presented. Participants were asked to report one syllable from each trial. Results showed that responses were slower on trials where one of the presented syllables had also been presented on the previous trial. Within these trials, the repeated syllable was selected less frequently, and the responses doing so were slower. Examined according to response choice on the preceding trial, syllables that had been ignored on the preceding trial tended to be ignored on the current trial (negative priming), while syllables that had been selected on the preceding trial tended to be selected on the current trial (positive priming). Responses that followed these selection biases were faster than responses that did not. Response selection was also influenced by the attention direction cue for the current trial, but not by the cue presented on the preceding trial. The results support an attentional model where traces from the preceding processing are retained, and current selection is biased to minimize cognitive conflict between recent and current processing. Negative priming appears to be due to after-effects of preceding processing, independently of the intentions behind that processing. The study accounts for positive and negative priming of dichotic listening sequences within an established, computationally viable biased competition framework.     

A comparison of two online cognitive‐behavioural interventions for symptoms of depression in a student population: The role of therapist responsiveness

Objectives: The study aimed to compare the efficacy of eight weekly sessions of a self‐administered online CBT treatment (cCBT; n=51) to a therapist‐assisted email CBT treatment (eCBT; n=50) in University students. Design: The design was a randomised parallel group trial. The study randomised participants with symptoms of depression to one of two available treatments. Method: Participants were offered eight weekly sessions of either cCBT or eCBT. Participants completed the Beck Depression Inventory‐II (BDI‐II) and the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE‐OM) at pre‐and post‐treatment, at weeks 16 and 32 follow‐up. The Working Alliance Inventory‐Short Form (WAI‐SR) was completed at weeks 2, 4, and 6. Results: For both groups, pre‐post within group effect sizes reported were large for the BDI‐II and the CORE‐OM and these were maintained at follow‐up. Perceptions of working alliance were similar in each group, but Bond was significantly stronger for the eCBT condition. WAI scores correlated more positively with the outcome on BDI‐II for those in the eCBT condition than the cCBT condition, but not significantly. Conclusion: There were no significant differences between the two online treatments, both reduced depressive symptoms and improved general functioning. Similarly, at post‐treatment and follow‐up, clinical improvement and recovery was demonstrated for both groups equally. The study demonstrates the possibility for cCBT in a university setting that may contribute to addressing the shortcomings in meeting increasing demands that mental health services presently face.     

关于健康观认知构造的中日比较研究

本研究的目的是揭示大学生关于健康观的认知构造,并对中日大学生健康观的认知构造进行比较。通过对收集到的日常生活的健康观数据进行处理,制成了一个包含50个项目的问卷,然后对收集到的儿8名日本大学生和81名中国大学生的数据进行了因子分析,得到了健康观认知构造的五个因子,即“自律性”(因子Ⅰ)、“主观自我”(因子Ⅱ)、“身体因素”(因子Ⅲ)、“心理因素”(因子Ⅳ)、“健康习惯”(因子Ⅴ)。中日学生的健康观认知结构在Ⅰ、Ⅲ、Ⅳ因子上存在差异。     

认知风格对不同类型几何问题解决的影响

通过镶嵌图形测验（EFT）,在初中学生中选了不同认知风格的被试,限时考查被试对不同类型几何问题的解决。结果表明：新问题与所学内容相似性会影响中学生几何问题解决的成绩;认知风格不同类型在几何问题解决中存在显著差异,在与所学内容相似性高的新问题解决中,场依存性学生的成绩显著地高于场独立性的学生。     

加工焦点性和任务负荷对不同认知方式大学生前瞻记忆的影响

采用双任务范式,探讨了加工焦点性和进行中任务负荷对不同认知方式大学生前瞻记忆的影响。包括两个实验:实验一探讨进行中任务与前瞻记忆任务加工的焦点性和加工类型的一致性对不同认知方式大学生前瞻记忆的影响;实验二探讨进行中任务负荷对不同认知方式大学生在在焦点加工和非焦点加工条件下前瞻记忆的影响。结果显示:焦点加工条件下的前瞻记忆成绩高于非焦点加工,且不受进行中任务负荷的影响;不管进行中任务与前瞻记忆任务的加工类型是否一致,在进行中任务负荷较高且非焦点加工条件下,场独立大学生的前瞻记忆成绩高于场依存大学生。本研究结果支持多重加工理论。     

大学生场依存性─－独立性认知方式分析

对二十一个学科专业１５２６名大学生的场依存性─－独立性认知方式进行调查所获得的新近常模资料表明：大学生场依存性─－独立性个体差异的群体分布是正态性的,其总体平均水平以《认知方式图形测验》成绩作指标为１３．７（ｓ为４．６）。在此基础上,对文献所报道的影响场依存性─－独立性发展水平的两个因素作了进一步的研究分析,发现,大学生场依存性─－独立性的性别差异非常接近显著水平;专业分化是不依赖于性别因素而导致大学生场依存性─－独立性水平显著不同的主要因素．     

赌博障碍的认知功能缺陷及神经基础

赌博障碍是指持续且反复的赌博行为,给个人、家庭和社会都带来了严重后果,近年来受到越来越多研究者的关注。本研究总结了赌博障碍的认知功能缺陷及其神经基础,主要集中在如下四个方面：①认知扭曲、②奖赏和惩罚敏感性、③注意偏向和④决策。未来研究应多从认知神经科学角度深入探究赌博障碍的发生机制和发展过程,关注大脑结构变化及功能网络改变,并将其整合到一个统一的神经生物机制框架中,找到更加有效的干预和治疗手段。     

Linguistic Analysis of Written Narratives of Caregivers of Children and Adolescents with Chronic Illness: Cognitive and Emotional Processes and Physical and Psychological Health Outcomes

Used linguistic analysis of written narratives of caregivers of hospitalized youth with chronic illness to identify emotional and cognitive processes related to physical and psychological health outcomes following writing. Measures were administered at baseline and 4 months. Experimental group (n = 29) wrote about traumas whereas the control group (n = 24) wrote about summer activities for 20 min on three different days. Compared groups on negative emotion- and cognition-related word use. Tested change in negative emotion- and cognition-related word use as predictors of outcomes in experimental group. Consistent with hypotheses, experimental group used more negative emotion words [F(1, 53) = 77.55, p < .001] and cognition-related words than control group [F(1, 53) = 19.09, p < .001] and an increase in cognition words predicted Physical Health Summary Score on SF-36 (standardized = .37, p < .05). A decrease in negative emotion words was related to Physical Health Summary Score on SF-36 only when entered into regression with change in cognition words (standardized = –.31, p < .05). A decrease in negative emotion together with an increase in cognitive processing facilitated by written emotional disclosure has beneficial effects on physical health-related quality of life.     

以实质心理学为基础的评估：认知诊断

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础：知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。
