不同阅读水平儿童中央执行系统比较研究

本研究通过两部分实验探讨汉语发展性阅读障碍儿童与正常儿童中央执行系统的容量差异和这种差异的性质。通过比较匹配生理年龄的不同阅读水平儿童在自定步速和固定步速的复杂阅读广度测验中的成绩,发现发展性阅读障碍儿童在两种阅读广度测验中都表现出中央执行系统容量的缺陷,这种缺陷既不能用加工效率理论,也不能用资源分配理论来解释,而符合一般容量假设。因此,本研究支持发展性阅读障碍儿童存在实时加工和存储信息的一般容量缺陷。     

The Learning of Programmed- and Feedback-Based Processes Controlling the Production of a Positioning Response in Two Dimensions

Two experiments were conducted to investigate the learning of the programmed- and feedback-based processes controlling the production of a slow, self-paced positioning response in two dimensions (direction and extent) in the horizontal plane. Both experiments had two phases: an acquisition phase of 60 trials with KR, followed by a KR withdrawal phase of 20 trials. In Experiment 1, one group (N=15) had visual feedback about the ongoing movement and the other group (N=15) did not. In Experiment 2, one group (N=15) practiced initiating the response in the criterion direction and moving the criterion extent, whereas, the other group (N=15) practiced initiating the response in the criterion direction and moving randomly varied extents. The results of Experiment 1 indicated that the learning of a programmed-based process is a gradually acquired freedom from visual feedback. Experiment 2 revealed that a programmed-based process can be learned independent of a feedback-based process.     

The effects of lesions in the central nucleus of the amygdala on appetitive classical conditioning in rats

Abstract: Lesions in the central nucleus of the amygdala (cAMY) have been known to interfere with the acquisition of fear classical conditioning when footshock is used as an unconditioned stimulus (US). The present study examined whether or not a similar interference would occur with an appetitive US. Five rats with lesions in the cAMY (the cAMY group), and eight unoperated control rats were trained in an appetitive classical conditioning paradigm, which did not include elements of operant learning, using a visual conditioned stimulus (CS) (5 W of light for 10 s duration) paired with a food pellet US (45 mg, cheese flavor). The behavioral index of appetitive conditioning was an increase in rearing approach behavior to the CS after CS and US pairings. During CS and US pairings, the movement of the rat was limited so that this approach behavior could not occur. As a result, all control rats showed an increase in rearing, but the cAMY group did not. These results suggest that the cAMY is critical for appetitive as well as fear classical conditioning.

Effet d'attitude dans le processus de structuration d'une représentation sociale

This research aims at clarifying the role of attitude in the structuring process of a social representation. It comes within the scope of Serge Moscovici's genetic approach and Jean-Claude Abric's central core theory. We have studied an object, the Internet, whose social representation is structuring itself in the social group of tradesmen and our hypothesis is that attitude has an influence on the organization of the representational field before the emergence of a stabilized structure. The results suggest the existence of a structuring and accelerating effect due to positive attitude.     

The 'self' in analytical psychology: the function of the 'central archetype' within Fordham's model

This paper concerns the self as Fordham came to conceive it after a conceptual analysis of Jung's use of the term. Fordham identified a contradiction in Jung's usage, and resolved it by reserving 'self' for a definition of the psychosomatic entirety of the individual, and using a separate term for referring to expressions of the self in human experience (e.g. symbols). Fordham tentatively suggested that the latter be termed the 'central archetype', although this was neither developed nor dropped. I explore the value of this term from a developmental perspective and, more specifically in terms of the deintegration of psyche out of an early psychosomatic unity. This draws upon infant research and an observation of a 14-month old boy. Finally, further developments are briefly described and illustrated, whereby pre-symbolic expressions of the central archetype become symbolic and come to reflect what was for Jung, the 'ultimate', 'Formation, Transformation, Eternal Mind's eternal recreation'.     

工作记忆中央执行成分对估算表现的影响

工作记忆中央执行成分在计算加工的诸多过程中发挥重要影响。以82名大学生为被试,采用双任务实验范式考察工作记忆中央执行成分对估算表现的影响。结果发现：1）估算过程需要中央执行成分的参与,增加中央执行成分负荷会导致估算准确率下降;2）无论是否增加中央执行负荷,问题大小效应在估算中均不明显;3）乘法个位数大小顺序会影响估算值的准确性,在有中央执行负荷时数字顺序效应明显。     

Attentional Limitations in Doing Two Tasks at Once

ABSTRACT— People generally have difficulty doing two tasks at once. To explain this fact, theorists have proposed that central processing—the thought-like stages following perceptual encoding and preceding response processing—takes place for only one task at a time. Because this bottleneck imposes severe limits on human cognitive processes, research has attempted to find exceptions. There is now solid evidence that, at least in the laboratory, the entire bottleneck can be completely bypassed under favorable combinations of circumstances. While these findings provide a ray of hope for enabling parallel multitasking in real-world scenarios, it will not be easy to take advantage of the combination of conditions that appear to be necessary.
