学习困难青少年认知控制特点研究

本研究基于双重认知控制理论,通过比较学困组和对照组在持续性操作任务上的表现来探究学习困难青少年的认知控制特点。结果发现：（1）在反应性控制的指标上,学困组和对照组的反应时和正确率不存在显著差异,但学困组对探测刺激的辨别力指数更低,显示学困组的反应性控制能力存在一定不足;（2）在主动性控制的指标上,学困组的反应时更长、正确率更低,且对线索刺激的辨别力指数更低,显示学困组在对线索刺激保持的各项指标上都比对照组更差,说明学困组在主动性控制上的缺陷更为明显。     

Image du corps chez l’enfant sourd. Perception et vécu à travers le dessin et le TSEA

The body is as a living entity with three interrelated aspects: the physical motor skills, development processes, social and emotional interaction. The young child, regardless of his mental or physical condition, appropriates this entity when he is in contact with the surrounding world. Thus, the self-image will depend, in large part, on the person he is, the situation in which he lives (society, family), the nature and frequency of surrounding stimuli. A child carrying a handicap is likely to have a poor representation of his own self-image (disproportionate or deformed body) and an altered self-image, as far as he lives in a rejecting environment. In this paper, we have focused our research on how deaf children sees their self-image, based on our nineteen years of experience as a psychologist with hearing impaired children, in special schools. The various observations and assessments in this research, in addition to groups support offered to parents during all these years, give us today enough elements to show what kind of self-image the deaf child has of himself. Our assessment material was essentially thematic projective test of socialization –TSEA– and the drawing of the person.

Extreme elemental processing in a high schizotypy population: Relation to cognitive deficits

The cognitive deficits observed in schizophrenia have been characterized as a failure to utilize task-setting information to guide behaviour, especially in situations in which there is response conflict. Recently, we have provided support for this account; high schizotypy individuals demonstrated inferior biconditional discrimination performance compared to low scorers, but were not impaired on a simple discrimination that did not require the use of task-setting cues. These results may, however, also be explained by the way in which individuals with high schizotypy process stimulus compounds. Here, we examine the initial approaches to solving biconditional and control discrimination tasks of participants with high and low schizotypy scores. In particular, we focus on performance during the first block of training trials to capture processing style before the acquisition of the discrimination tasks. Participants scoring highly on the introvertive anhedonia subscale (which has been allied to the negative and cognitive symptoms of schizophrenia) demonstrated better biconditional performance during the first block of training trials than did low-schizotypy individuals, consistent with a highly elemental approach to stimulus processing. Subsequent recognition tests confirmed this analysis demonstrating that the pattern of performance observed in participants with high schizotypy was associated with a failure to discriminate conjunctions of items that had been seen before from those that had not. These results suggest that the negative/cognitive symptoms of schizophrenia may reflect an extreme bias towards elemental, as opposed to configural, processing of stimulus conjunctions.     

False memories in patients suffering from obstructive sleep apnoea syndrome (OSAS)

We assessed the propensity for false memories among patients with obstructive sleep apnoea syndrome (OSAS). Twenty-one patients with OSAS and 21 controls matched for sex, age and education were recruited. At encoding, an adaptation of the Deese-Roediger-McDermott paradigm was used to induce false memories. At retrieval, participants completed a forced-choice recognition task to distinguish memories based on verbatim traces from those based on gist traces. When the task encouraged retrieval based on either gist or verbatim traces, the groups performed similarly. However, when the task required retrieval based solely on verbatim traces, OSAS patients exhibited poor discrimination and produced more false memories. Our finding that OSAS leads to an increased propensity to produce false memories is discussed within the framework of both fuzzy-trace theory and activation-monitoring theory.

A dual-process model of affective and instrumental attitudes in predicting physical activity

IntroductionA novel dual-process model based upon the affective-reflective theory which distinguishes between affective attitude and instrumental attitude at an explicit and implicit level was used to predict physical activity.MethodUndergraduate students (N = 114) completed a lab-based study at two time-points, spaced two weeks apart. Participants completed self-report measures of the theory of planned behavior constructs, including explicit affective attitude and explicit instrumental attitude. Implicit affective attitude and implicit instrumental attitude were measured using single category implicit association tests.ResultsExplicit affective attitude and perceived behavioral control indirectly predicted physical activity through intention, and explicit affective attitude, implicit affective attitude, and intention predicted physical activity directly with a modest effect size (R² = 0.24).DiscussionFindings suggest explicitly and implicitly held evaluative information are conceptually distinct, and affective evaluations are key in guiding physical activity behavior regardless of whether such evaluations are implicit or consciously accessible.     

What is to be done?

The overriding question in contemporary philosophy is as follows: We now have a reasonably well-established conception of the basic structure of the universe. But it is not at all easy to reconcile the basic facts we have come to know with a certain conception we have of ourselves, derived in part from our cultural inheritance but mostly from our own experience. Various aspects of this question are examined, concerning consciousness, intentionality, language, rationality, free will, society and institutions, politics, and ethics.
