The development of self-regulatory systems during the preschool years is accompanied by a dramatic increase in the ability to inhibit actions based on the directions of others. Several tasks have shown evidence of changes in self-regulation during the fourth year of life. The current cross-sectional study used a Simple Simon task, in which 33 3- to 4-year-old children were asked to respond to the command of one large toy animal but not to the command of another. Three important aspects of self-regulation were examined: the ability to inhibit action in the face of conflict, error detection/correction and the use of verbal and physical control strategies. The ability to inhibit a response in this task increased from 22% to 90% between 36 and 48 months of age. Post error slowing of Reaction Time (RT) indicative of error detection emerged at about the same age as successful inhibition. Physical rather than verbal self-regulation strategies were spontaneously employed by children to aid in the process of inhibition. 相似文献

Magnitude estimates of haptic extent resulted in positively accelerated psychophysical power function with an exponent of 1.18. However, in two further experiments right-handed male subjects made rating-scale judgements of the combined width of two stimulus blocks. Six widths were used and five replications of the 36 factorial combinations were presented to each subject. In Experiment II both stimuli were out of view and one was held between the thumb and index finger of each hand. In Experiment III one stimulus was held out of view between thumb and finger of the right hand and the second was shown to the subject. Mean ratings in both experiments were fit by a model which assumes that responses are a weighted average of the scale values of the two stimuli (Anderson, 1974a). 相似文献
