海马突触传递长时程增强效应中的蛋白激酶

对海马突触传递长时程增强效应的研究已取得许多重要进展,其中发现很多蛋白激酶的参与,近年来由于转基因和基因打靶等分子生物学实验手术的应用,ＰＫＣ,ＣａＭＫⅡ和ＰＫＡ等多种蛋白激酶的同功酶或其不同亚单位在ＬＴＰ中的作用已在相应的变异小鼠上得到直接证实,文章概述了这些目前被认为参与了海马突触传递长时程增强过程的蛋白激酶及其作用。     

成人非字词作业速度的随龄减慢及其与汉字作业的比较

以３００名２０￣７９岁成人为被试,并以１０岁段划分为６个年龄组,完成了非字词作业速度的随龄减慢及其与汉字作业的比较研究。结果表明：（１）数字鉴别、数字旋转、心算、符号数字和图形空间定位五项非字词作业均随增龄而显著减慢;（２）元分析结果表明３０－３９岁组到７０－７９岁组５个年龄组上述非字词作业反应时均为２０－２９岁组的平方函数,而且,非字词作业速度减慢的程度在６０岁后明显增大;（３）符号数字和数字鉴     

归因疗法——一种重要的心理治疗方法

归因疗法是心理治疗的重要方法之一。迄今为止 ,人们已经发展了运用归因理论于治疗实践的两种一般模式 :“真归因疗法”引导患者用准确的归因代替错误的归因 ,“误归因疗法”引导患者用不准确而有益的归因代替准确而有害的归因。归因疗法受到了其他心理治疗理论的怀疑和批评。

Eye-movement-contingent display changes are not compromised by flicker and phosphor persistence

The eye-movement-contingent display change technique has been used in a large number of studies to control the visibility of text when eye movements are monitored. Recently, the validity of the method has been questioned. O’Regan (1990) argued that technical imperfections in the implementation of the display change, rather than manipulation of visible text, account for some of the reported effects. This view was tested in the present study by manipulating characteristics of the display change and the linguistic task. Consistent with prior results, reading was hampered when eye-movement-contingent display changes were used to mask segments of text prior to their fixation. However, these costs were unrelated to the quality of the implemented display change and appear to have derived solely from the masking of useful text.

Do incompatible arguments cause extensive processing in the evaluation of arguments? The role of congruence between argument compatibility and argument quality

Previous studies have demonstrated that arguments incompatible with prior beliefs are subjected to more extensive refutational processing, scrutinized longer, and judged to be weaker than arguments compatible with prior beliefs. However, this study suggests whether extensive processing is implemented when evaluating arguments is not decided by argument compatibility, but by congruence between two evaluating tendencies elicited by both argument compatibility and argument quality. Consistent with this perspective, the results of two experiments show that relative to congruent arguments, participants judged arguments eliciting incongruent evaluating tendencies as less extreme in strength, spent more time, and felt more hesitant generating strength judgments for them. The results also show that it is mainly incongruent arguments, not congruent arguments, whose strength ratings were more closely associated with the perceived personal importance of the issue, which intensified the tendency to evaluate arguments depending on argument compatibility. These results suggest that it is the incongruity between argument compatibility and argument quality, and not simply the argument compatibility, that plays a more important role in activating an extensive processing in the evaluation of arguments.     

In search of the ‘Aha!’ experience: Elucidating the emotionality of insight problem‐solving

Although the experience of insight has long been noted, the essence of the ‘Aha!’ experience, reflecting a sudden change in the brain that accompanies an insight solution, remains largely unknown. This work aimed to uncover the mystery of the ‘Aha!’ experience through three studies. In Study 1, participants were required to solve a set of verbal insight problems and then subjectively report their affective experience when solving the problem. The participants were found to have experienced many types of emotions, with happiness the most frequently reported one. Multidimensional scaling was employed in Study 2 to simplify the dimensions of these reported emotions. The results showed that these different types of emotions could be clearly placed in two‐dimensional space and that components constituting the ‘Aha!’ experience mainly reflected positive emotion and approached cognition. To validate previous findings, in Study 3, participants were asked to select the most appropriate emotional item describing their feelings at the time the problem was solved. The results of this study replicated the multidimensional construct consisting of approached cognition and positive affect. These three studies provide the first direct evidence of the essence of the ‘Aha!’ experience. The potential significance of the findings was discussed.     

Stereotype activation is unintentional: Behavioural and event‐related potenials evidence

In this study, a priming Stroop paradigm was used to determine whether stereotype activation is unintentional. Priming conditions (priming/no‐priming) and the relationship between priming and target (consistent/inconsistent/no‐relation) were the independent variables; accuracy, reaction time and N400 amplitude were used as dependent variables. The reaction time revealed that stereotype activation is, to some extent, unintentional. Furthermore, the event‐related potenial (ERP) results showed that N400 amplitude was larger for inconsistent conditions than for consistent conditions. This result supported the notion that stereotype activation is an unintentional and automatic process.     

Maternal Depression and Adolescent Emotions: The Role of Family Functioning

Maternal depression may affect children through various mechanisms, including the stressful contexts of the children’s lives and maternal maladaptive affection, behaviors, and cognition, which affect the psychopathological development of children and contribute to disorders. The aims of the present study were to explore how family functioning mediates the relationship between maternal depression and the positive and negative emotions of adolescents. A total of 430 paired questionnaires were collected from junior high school students and their mothers. The mothers completed the Center for Epidemiologic Studies Depression Scale (CESD), and the adolescents completed the CESD, Mood and Anxiety Symptom Questionnaire, and Family Function Scale. The results revealed significant correlations among maternal depression, family functioning, and positive and negative emotions in the adolescents. The family functioning subscales of conflict and emotional expression partially mediated the relationship between maternal depression and the positive and negative emotions of the adolescents. Furthermore, the family functioning subscales of cohesion, problem solving, and responsibility fully mediated the relationship between maternal depression and positive moods in the adolescents. Analysis of the results for maternal depression, family functioning, and the emotional adjustment of the adolescents indicated that family functioning is the mediator between maternal depression and the positive and negative emotions of the adolescents. The current results suggest that adequate family functioning can prevent depression being transmitted from mothers to their adolescent children.
