注意控制与短时记忆的知觉组织

、考察了短时记忆中的知觉组织是否受双作业时指导语引导的注意策略控制。各有24名北京大学本科生参加了自由回忆和顺序回亿实验。实验任务有2种：记忆和声音监控。声音监控或者安排在记忆编码阶段,或者安排在记忆提取阶段。双作业时的指导语类型有3种,分别强调记忆、声音监控或两种作业同样重要。记忆项目表分2种：不分组和知觉分组。研究发现：自由回忆中的知觉组织仅受编码阶段的指导语影响;顺序回忆中的知觉组织仅受提取阶段的指导语影响。作者设想,短时记忆中的知觉组织在编码和提取阶段都受注意控制,但记忆类型不同,注意控制的作用地点和表现形式也有所不同。     

Developing an emotion-focused therapy model for fear of cancer recurrence: A case-level task analysis

Fear of cancer recurrence (FCR) involves anxiety about the possible return or progression of the disease. It is common among people surviving cancer, covering a range of adaptive and maladaptive responses including clinical presentations of FCR, for which different psychological interventions have been developed, most within the cognitive-behavioural paradigm. Recently, emotion-focused therapy (EFT) has been proposed as an alternative and has been the subject of research focusing on the cancer population and cancer-related issues, including FCR. In this study, we looked closely at a successful case from a larger exploratory study, carrying out a discovery-phase task analysis aimed at identifying the main components of EFT–FCR. We found that this approach generally followed the usual structure of an EFT intervention, with four distinct phases. However, we identified some specific secondary processes (e.g., hypervigilance and catastrophising) and clarified the nature of the core pain in this presentation as existential (e.g., fear of dying).     

Angry reactions to failure on a cooperative computer game: The effect of trait hostility,behavioural inhibition,and behavioural activation

This study describes the use of a “cooperative” computer game in which the subject has to follow directions, supposedly sent from a partner, and steer a tank to avoid invisible mines. The tank is lost if it hits a mine or does not reach base within a set time limit. The game was designed so that the majority of trials would be lost. Affective (mood self-ratings), cognitive (attribution of blame questionnaire), and behavioural (feedback sent to the “partner”) outcomes were assessed. The game significantly increased ratings of discontentedness and anger. Self-blame for task failure was correlated with the Guilt subscale of the Buss-Durkee Hostility Inventory (BDHI), and blaming the partner was correlated positively with the Motor Aggression subscale and negatively with the empathy scale of the I7, supporting the notion of hostile attributional bias in adults. The importance of individual differences in the strength of the behavioural inhibition system (BIS) and behavioural activation system (BAS) were explored using the BIS/BAS scales developed by Carver and White [1994]. Sending negative feedback to the partner was negatively correlated with scores on the BIS. Scores on BAS drive were positively correlated with increases in discontentedness and with sending negative feedback on trials when the tank was lost due to lack of time. These results are discussed in relation to Berkowitz's [1993] model of affective aggression. Aggr. Behav. 24:27–36, 1998. © 1998 Wiley-Liss, Inc.     

金钱惩罚促进Stroop任务中的行为表现

本研究通过Stroop任务和修改版MIDT相结合,目的是考察不同额度金钱惩罚对Stroop任务行为表现的影响。结果发现：（1）无论是中性试次,一致试次还是不一致试次,金钱惩罚不仅减少了被试的行为反应时,而且提高了正确率;（2）非惩罚条件与惩罚条件下的冲突效应以及其他不同额度惩罚条件下的冲突效应差异不显著;（3）金钱惩罚对不一致试次反应时的影响与个体的惩罚敏感性呈显著负相关,而与奖赏敏感性无关。结果表明,金钱惩罚能够促进个体的一般行为表现,但是不会提高冲突抑制能力。同时,金钱惩罚对认知行为的影响与其惩罚敏感性密切相关。     

得失框架效应的分离—— 来自收益与损失型跨期选择的研究

本研究通过创设收益和损失跨期选择情境, 采用不同表征方式(得框架、失框架)的跨期选择任务, 分别探讨了收益和损失情境下的跨期选择是否存在得失框架效应, 及其是否会受任务难度的影响。结果发现：(1)收益型跨期选择只在任务容易时存在得失框架效应, 与失框架相比, 被试在得框架下选择即时获益的概率更高; 任务困难时得失框架效应消失(实验a); (2)损失型跨期选择中不存在得失框架效应(实验b)。结果表明, 得失框架效应在损、益型跨期选择中出现了分离, 收益型跨期选择中的得失框架效应的内在认知机制很可能与风险决策中的框架效应类似并且是一种较为初级的认知加工过程。     

早老性痴呆病人早期记忆损害的检测方法

采用词语延迟回忆、记忆广度和双任务工作记忆测验,研究可能用于检测(Alzheimer’s disease,AD)早期记忆损害的方法。共有4组被试：两个正常年轻人组、一个正常老年人组、一个很可能患早老性痴呆病人(Probable AD,PAD)组。结果表明：(1)正常年轻人和正常老年人的词语延迟回忆保持率没有显著差异,而PAD患者表现出明显受损;(2)两个正常年轻人组的双任务工作记忆成绩也没有显著不同,与之相比,正常老年人组有一定程度的降低,而PAD患者表现出更大程度的损害;(3)4组被试的记忆广度都不相同。这些结果提示,词语延迟回忆和双任务工作记忆测验可能能够用于检测AD早期的记忆损害。     

单字词的学习年龄对小学生汉字识别的影响（Ⅰ）

该研究以小学一、三、五年级的学生为被试,采用字词的真假判断任务,选取分别在语文课本中一、三、五年级出现的三组字(分别记为A、B、C三组字)为真字,考察了单字词的学习年龄(LA)对小学生汉字识别时间的影响。结果表明：无论纵向比较还是横向比较,单字词的学习年龄(LA)对小学生的真假字判断反应时都有显著影响。     

双重作业的颜色编码方式对作业绩效的影响

研究探讨了不同颜色编码方式对双重任务操作绩效的影响。实验结果证明：若采用同类颜色编码方式,同时操作的两种作业就会产生结构限制,降低双重任务操作绩效;相反,若采用异常颜色编码方式,将有效地减少双重任务操作的结构限制,使双重任务的操作绩效得到提高。     

Extending Fitts' law to a three-dimensional pointing task

An attempt was made to extend Fitts' law to a three-dimensional movement (pointing) task to enhance its predictive performance in this domain. An experiment was conducted in which 10 subjects performed three-dimensional pointing movements under the manipulation of target size, distance to target and direction to target. As expected, the duration of these three-dimensional movements was rather variable and affected markedly by direction to target. As a result, the variance in the movement times produced was not satisfactorily explained by the conventional Fitts' model. The conventional model was extended by incorporating a directional parameter into the model. The extended model was shown to better fit the data than the conventional Fitts' model, both in terms of r(2) and the standard error of the residual between the measured movement time and the value predicted by model fit.
