心算加工的认知神经科学研究 总被引:5,自引:0,他引:5
近几年(1999-2005)有关心算加工的脑活动机制研究发现,类似九九乘法表这样的算术知识提取(如3×5)主要与左脑顶内沟有关,但当心算变得更复杂时(如26×38),左脑额叶下部出现明显激活,这表明心算与语言和工作记忆关系密切。另一方面,也存在不依赖于语言的即表现为视觉表象活动的心算,右脑的一些脑区在其中起了作用。简言之,所有与心算有关的脑区涉及到大脑前额皮层和颞顶枕联合皮层的综合作用,并总体表现为左脑优势,但具有特殊心算能力的人其心算还与右脑前额叶和颞叶内侧脑区的活动有关。 相似文献

It has been argued that the psychological refractory period (PRP) effect is eliminated with two ideomotor compatible tasks when instructions stress fast and simultaneous responding. Three experiments were conducted to test this hypothesis. In all experiments, Task 1 required spatially compatible manual responses (left or right) to the direction of an arrow, and Task 2 required saying the name of the auditory letter A or B. In Experiments 1 and 3, the manual responses were keypresses made with the left and right hands, whereas in Experiment 2 they were left-right toggle-switch movements made with the dominant hand. Instructions that stressed response speed reduced reaction time and increased error rate compared to standard instructions to respond fast and accurately, but did not eliminate the PRP effect on Task 2 reaction time. These results imply that, even when response speed is emphasized, ideomotor compatible tasks do not bypass response selection. 相似文献

This qualitative study explored how 16 counselors conceptualize and address issues of privilege and oppression in the counseling session as well as how they perceive their training with respect to these constructs. In an effort to bridge multicultural training and counselor practice, implications for counselor training are provided based on the clinical and academic experiences counselors reported. Additionally, future research directions are included. 相似文献

The study developed a Big 6 Information Problem-Solving Scale (B61PS), including the subscales of task definition and information-seeking strategies, information access and synthesis, and evaluation. More than 1,500 fifth and sixth graders in Taiwan responded. The study revealed that the scale showed adequate reliability in assessing the adolescents' perceptions about the Big 6 information problem-solving approach. In addition, the adolescents had quite different responses toward different subscales of the approach. Moreover, females tended to have higher quality information-searching skills than their male counterparts. The adolescents of different grades also displayed varying views toward the approach. Other results are also provided. 相似文献

IAT范式下自尊内隐性的再证明 总被引:4,自引:0,他引:4
该研究用IAT测量了被试的内隐自尊,并通过操纵被试在不同的认知负荷条件下进行外显自我评价来考察外显自我评价和内隐自尊之间的关系。得到的结论是,在低认知负荷条件下进行外显自我评价时,外显自我评价和内隐自尊没有表现出一致性;在高认知负荷条件下进行外显自我评价时,外显自我评价和内隐自尊表现出一致性。该研究在IAT范式下表明了内隐自尊和外显自尊的分离,内隐自尊具有无意识性和自动化的特点。 相似文献

Diagnosis and treatment of cancer has been associated with both posttraumatic stress disorder (PTSD) symptoms and posttraumatic
growth (PTG). This cross-sectional study sought to assess the frequency, common predictors, and interrelationships of PTSD
symptoms and PTG in breast cancer survivors (n = 65). In this sample, symptoms of PTSD and reports of PTG were common and were not significantly related to one another.
Greater social constraints on talking about breast cancer and perception of cancer as a traumatic stressor were associated
with greater PTSD symptomatology. Younger age and perception of cancer as a traumatic stressor were associated with greater
PTG. Findings suggest the central role of subjective appraisal in adjustment to cancer. Psychosocial interventions should
be sensitive to the potential for PTG, both in treatment design and in assessment of outcomes. 相似文献

Belief in a just world, where people get what they deserve, has been hypothesized to underlie a variety of psychological phenomena (Lerner, 1965). Close inspection of individual difference measures of this belief, however, has indicated repeatedly that just world beliefs are not a unidimensional construct. The purpose of this investigation was to elaborate upon the conceptualization of unjust world beliefs as a related but separate construct from just world beliefs. In two studies, the Unjust World Views scale (UJVS) was developed and its reliability and validity examined. The UJVS demonstrated acceptable reliability and validity and accounted for more variability in related outcomes than just world beliefs. Further, belief in an unjust world was related to defensive coping, anger, and perceived future risk. These findings contribute to theory development and suggest that a belief in an unjust world may serve a self-protective function. Clinical implications are discussed as unjust world views also were found to be potentially maladaptive. 相似文献

Disembodiment in online social interaction: impact of online chat on social support and psychosocial well-being. 总被引:1,自引:0,他引:1
Seok Kang 《Cyberpsychology & behavior》2007,10(3):475-477
This study investigates how disembodiment--that is, transcendence of body constraints in cyberspace--in online chat affects social psychological well-being. The results demonstrate that disembodiment is a strong predictor of increased loneliness and depression, and decreased social support. However, the amount of chat use is a positive contributor to decreased offline estrangement and depression, and increased happiness. These contrasting results suggest that online chat use is a technology for social connection used for offline connectivity, but the disembodiment motive is associated with declines in social support and psychosocial well-being. The investigation of specified motives for online interaction, personal competency, or advanced technological alternatives in interaction is suggested for future research on the effects of online interaction on offline outcomes. 相似文献
