The experiment investigated the effects of the mode and patterning of rehearsal on the acquisition and retention of modeled activities varying in organizational complexity. Subjects observed a filmed model construct two configurations, containing high or low organizational requirements. Immediately after exposure they rehearsed the modeled activities either mentally, motorically, mentally and then motorically, motorically and then mentally, or engaged in a distracting activity that prevented rehearsal of what they had see. Performance tests were conducted immediately after the rehearsal phase and again 1 week later. Subjects who rehearsed the modeled behaviors symbolically, whether singly or in conjunction with motor practice, reproduced both configurations more accurately than those who rehearsed motorically or not at all. Motor rehearsal increased speed on the organizationally simple task, but did not enhance response acquisition over and above observation alone. The overall results are interpreted as supporting the social learning view that modeled behaviors are best acquired when demonstrated activities are first organized symbolically and then refined on the basis of performance feedback. 相似文献

The Vocational Preference Inventory and the Edwards Personal Preference Schedule were administered to 372 undergraduates. The two instruments were compared using canonical analysis. The analysis revealed three significant relationships between components of the two instruments. The relationships were viewed as supportive of Holland's theory of personality types. 相似文献

Two experiments are reported in which Ss were required to determine whether a random, angular form, presented at any of a number of picture-plane orientations, was a “standard” or “reflected” version. Average time required to make this determination increased linearly with the angular departure of the form from a previously learned orientation. The slope and intercept of the reaction-time (RT) function were virtually constant, regardless of the perceptual complexity of the test form and the orientation selected for initial learning.When Ss were informed in advance as to the identity and the orientation of the upcoming test form and, further, were permitted to indicate when they were prepared for its external presentation, RT for determining the version of the form was constant for all test-form orientations. However, the time needed to prepare for the test-form presentation increased linearly with the angular departure of the form from the learned orientation.It is argued that the processes both of preparing for and of responding to a disoriented test form consist of the mental rotation of an image, and that both sorts of mental rotation (pre-stimulus and post-stimulus) are carried out at essentially the same constant rate. 相似文献

Two separate experiments were conducted to investigate transfer of persistence between delay and a downshift in reward magnitude. In the first experiment, experimental rats were initially downshifted in reward magnitude and later tested for persistence to continuous delay of large reward. It was found that these rats were more persistent to the effects of delay than control rats which did not receive prior experience with a downshift in reward magnitude. In the second experiment, experimental rats were first trained to receive large reward under delayed conditions and then tested for persistence to a downshift in reward magnitude. Compared to control rats which received no prior experience with delay, the experimental rats showed a significantly smaller negative contrast effect. The results were interpreted as supporting Amsel's theory of persistence as well as Capaldi's recent interpretation of contrast effects. 相似文献

The present investigation examined the effects of different types of participation (choice) and role models in goal setting on goal acceptance, goal satisfaction, and performance. It was hypothesized that choice in setting a goal and a strategy to achieve the goal would positively benefit goal acceptance, performance, and goal satisfaction. In addition, it was predicted that a role model would differentially influence an individual's goal acceptance, goal satisfaction, and performance. One hundred twenty male college students working on a class scheduling task were exposed to either a high- or low-performing role model and given various amounts of choice in the goal-setting process. The results of two-way analyses of variance demonstrated that goal acceptance, goal satisfaction, and performance were highest for individuals given choice over their goal and their strategy to achieve the goal. In addition, the results demonstrated that an individual exposed to a high-performing role model outperformed and had higher goal acceptance and satisfaction than an individual exposed to a low-performing model. The results are discussed as a means for clarifying the effects of different types of choice in the goal-setting process and the importance of role-provided information in influencing an individual's performance. 相似文献

Human medial temporal-lobe stimulation disrupts both formation and retrieval of recent memories 总被引:2,自引:0,他引:2
Disrupting medial temporal-lobe (MTL) activity for less than a second, either during the initial presentation of a complex scene or when it is presented again 1 min later, severely impairs recognition at the second presentation. MTL disruption during both presentation and recognition periods produces further impairment. These results are not consistent with views limiting MTL function solely to encoding or solely to retrieval mechanisms. 相似文献

Perceptual asymmetries in face recognition 总被引:1,自引:1,他引:0
G Rhodes 《Brain and cognition》1985,4(2):197-218
Four experiments were carried out to investigate perceptual asymmetries in face recognition. Perceptual asymmetries favoring the half-face on the observer's left were found under free viewing conditions for both unfamiliar faces (Experiment 1) and famous faces (Experiment 3). For unfamiliar faces, this asymmetry was not obtained when fixation was controlled by presenting faces tachistoscopically (Experiment 2). For famous faces, the perceptual asymmetry favoring the half-face normally seen on the left did not appear to be retained in memory (Experiments 3 and 4). Asymmetries in face perception have been explained in terms of a direct access model of laterally effects. However, these results raise the possibility that asymmetric scanning or attentional factors may be important. 相似文献

Several tachistoscopic visual half-field experiments using exposure times in excess of 150 msec have been reported and arguments have been put forth justifying this procedure. An experiment was done investigating visual field accuracy under conditions where eye movement was allowed, following parafoveal exposure. Two control experiments were done to evaluate the viewing conditions. When eye movement is permitted, accuracy in both visual fields reaches 100%. It is concluded that visual field differences found with exposure times greater than 150 msec are due to the active cooperation of the subjects and not due to the justifications advanced by experimenters using long exposure times. 相似文献
