中小学生内隐序列学习的机制

内隐序列学习是内隐学习的一种重要形式。该文探讨了中小学生内隐序列学习的心理机制及次级任务影响内隐序列学习的实质。结果表明,中小学生对不同结构序列的内隐学习是由一个单一的学习机制完成的,学习的过程即是形成序列内相邻元素间联合的过程;另外,注意能量并不是内隐序列学习的重要影响因素,次级任务影响内隐序列学习并不是因为其分散了注意能量,而是破坏了对序列元素的组织。     

结构、任务类型和导航对超文本信息搜索的影响

通过两个实验考察了结构、任务类型和导航对超文本信息搜索绩效的影响。实验一采用2（层次结构,混合结构）×2（特定任务,关系任务）的被试内设计,探讨了超文本结构和任务类型对信息搜索的影响;实验二在实验一的基础上,采用2（层次结构,混合结构）×2（有导航图,无导航图）的被试内设计,考察超文本结构和导航对关系任务信息搜索的影响。结果表明：（1）超文本结构和任务类型对信息搜索绩效有显著的交互影响,就关系任务而言,混合结构超文本优于层次结构超文本,但就特定任务而言,两者无显著差异;（2）导航对信息搜索行为有指导作用,尤其对层次结构超文本有利;（3）两种主观指标的结果与客观指标存在一定程度的一致性。     

An experimental study about the congruence between type A behavior pattern and type of task

This paper is an experimental study, the basic aim of which is to check whether the congruence between personality characteristics and task characteristics has positive effects for performance and satisfaction on individuals. The results obtained reveal that Type A behavior pattern individuals get better results in cases of congruence than in cases of incongruence, while the performance of Type B behavior pattern individuals is not related to the (in)congruence between personal needs/aims and the task's demands. Besides, we have found that Type A behavior pattern individuals also have greater levels of satisfaction in cases of congruence than in cases of incongruence. However, Type B behavior pattern individuals show the same levels of satisfaction in both cases.     

自传体记忆的情绪对其相关信息内隐提取的影响

本研究主要考察自传体记忆本身的情绪是否影响该记忆相关信息的内隐提取过程。取大学生15人完成实验, 实验分为两部分：记忆提取和词汇判断。首先在记忆提取阶段, 要求被试根据词对(形容词-中性名词)提取积极、消极和中性情绪色彩的自传体记忆事件。接着在词汇判断任务中, 要求被试对包含提取过记忆的中性名词的词语进行词和非词的判断, 并且记录相应的脑电波。结果发现：(1)被试按要求成功提取了积极、消极和中性三类自传体记忆事件。词汇判断任务中, 内隐提取三类自传体记忆信息的反应时和正确率均无显著差异。(2)相比于积极、中性自传体记忆信息, 消极自传体记忆信息提取的过程中的ERP波幅更大, 更偏向于正向。这表明自传体记忆信息的内隐提取受到记忆本身情绪的影响, 消极自传体记忆信息提取需要付出更多资源。     

Engaging reluctant adolescents in family therapy: an exploratory study of in‐session processes of change

Informed by a trans‐theoretical model of the therapeutic alliance in conjoint family therapy, this exploratory study was the initial stage in a task analysis of critical shifts in adolescent engagement. Specifically, we compared sessions in which a resistant adolescent either did or did not shift from negative to positive engagement during the session. Two successful and two unsuccessful change events were selected from an archival data set based on SOFTA ratings of the therapeutic alliance. The results suggested that one parent element (support) and five therapist elements (structuring therapeutic conversations, fostering autonomy, building systemic awareness, rolling with resistance and understanding the adolescent's subjective experience) seemed critical for successfully facilitating adolescent engagement. The qualitative results were informed by the adolescent's self‐reported target complaints pretreatment, which suggested varying reasons for the teenagers’ active or passive disengagement. Implications for practice and recommendations for future research are offered to continue this line of inquiry.     

Attentional capture by emotional faces is contingent on attentional control settings

Attentional capture by schematic emotional faces was investigated in two experiments using the flanker task devised by Eriksen and Eriksen (1974). In Experiment 1, participants were presented with a central target (a schematic face that was either positive or negative) flanked by two identical distractors, one on either side (schematic faces that were positive, negative, or neutral). The objective was to identify the central target as quickly as possible. The impact of the flankers depended on their emotional expression. Consistent with a threat advantage hypothesis (negative faces are processed faster and attract more processing resources), responses to positive faces were slower when these were flanked by (response incompatible) negative faces as compared with positive or neutral faces, whereas responses to negative faces were unaffected by the identity of the flankers. Experiment 2 was a standard flanker task with letter stimuli except that the task-neutral flankers were schematic faces that were either positive, negative, or emotionally neutral. In this case, in which faces and emotional expressions were to be ignored, performance seemed entirely unaffected by the faces. This result suggests that attentional capture by emotional faces is contingent on attentional control settings.     

Characterisation of music-evoked autobiographical memories

Despite music's prominence in Western society and its importance to individuals in their daily lives, very little is known about the memories and emotions that are often evoked when hearing a piece of music from one's past. We examined the content of music-evoked autobiographical memories (MEAMs) using a novel approach for selecting stimuli from a large corpus of popular music, in both laboratory and online settings. A set of questionnaires probed the cognitive and affective properties of the evoked memories. On average, 30% of the song presentations evoked autobiographical memories, and the majority of songs also evoked various emotions, primarily positive, that were often felt strongly. The third most common emotion was nostalgia. Analyses of written memory reports found both general and specific levels of autobiographical knowledge to be represented, and several social and situational contexts for memory formation were common across many memories. The findings indicate that excerpts of popular music serve as potent stimuli for studying the structure of autobiographical memories.     

不同表面特征图片对内隐记忆和外显记忆的影响

该研究选取30名被试,采用任务分离实验研究范式探讨不同表面特征图片对内隐记忆和外显记忆的影响。以32张动物图片为实验材料,其中鱼类和鸟类图片各半。两类图片中一半为黑白图片,另一半为彩色图片,所有实验材料用E—Prime软件呈现在电脑上。结果表明：（1）不同表面特征图片的再认成绩（外显记忆）显著好于偏好再认成绩（内隐记忆）,即外显记忆成绩好于内隐记忆;（2）在再认测验和偏好判断测验中,再认成绩和偏好再认成绩在图片表面特征的两个水平上存在显著差异;（3）控制组的偏好再认成绩显著好于实验组的偏好再认成绩,即控制组的内隐记忆好于实验组。结论：刺激材料的表面特征既是外显记忆的内容,也是影响外显记忆的重要因素;内隐记忆的作业成绩高度依赖于刺激材料的表面特征,刺激材料的表面特征是影响两种记忆的重要因素。     

A functional analysis of another individual's behavior as discriminative stimulus for a monkey.

Key presses of 1 monkey (called the performer) became the basis upon which a 2nd monkey (called the judge) solved conditional-discrimination tasks. First, the performer was trained to press one of two colored choice keys (red or green) depending on the location of a white light in her chamber. The performer's key-pressing behavior was brought under the control of the experimenter by this procedure. Subsequently, the judge was trained to discriminate the performer's key-pressing behavior. In Experiment 1, the judge had to press Key 1 when the performer pressed the red choice key and Key 2 when the performer pressed the green choice key. In Experiment 2, a sample key was introduced. The judge had to press Key 1 when the performer pressed the same colored choice key as the sample; the judge had to press Key 2 when the performer pressed the different colored choice key. In both experiments, the judge was required to attend to the behavior of the performer. It was shown that the performer's behavior served as a discriminative stimulus for the judge's responses in a conditional-discrimination task.     

合作学习情境下监控者监控发音任务中的定向遗忘效应

在以构建留学生的汉字语音库为共同目标的合作学习情境下,考察了合作学习中的监控者是否会表现出定向遗忘效应。实验一中,协助者朗读两字表的单字并接受定向遗忘或记忆字表中单字的指令;监控者监控发音的流畅性或准确性,并单独接受再认测验;实验二在协助者重新朗读单字的条件下监控者接受再认测验。结果发现:(1)实验一中,监控者只在深层监控发音准确性的任务时,再认成绩表现出定向遗忘效应,浅层监控发音流畅性的任务中未表现出定向遗忘效应;(2)实验二中在测验阶段复原学习情境后,深浅监控任务下的再认成绩虽存在显著差异,但定向遗忘效应也消失了。综合两个实验表明,合作学习情境下,非有意遗忘的监控者的定向遗忘效应与监控任务深度和学习情境复原与否存在密切联系。
