In Experiment 1, 30 subjects at each of three age levels were shown pictures of unfamiliar “animals”. They were told two semantic attributes for each animal (e.g., kind and strong) and were asked to learn these sets so that, when shown a picture, the appropriate attributes could be recalled. The results indicated that the dimensional structure of the attributes had a strong effect on new learning for young children. Incongruent pairs of attributes (e.g., kind and ugly) were difficult to learn compared to congruent (e.g., kind and beautiful) or unrelated (e.g., kind and tall) sets. These results indicate: (a) Attribute structure is a factor in new learning; (b) 6-year-olds tend to organize the verbal labels for attributes into bipolar dimensions, rather than into independent clusters of attributes. The latter findings require reexamination of the meaning of previous word-association data which had been interpreted as indicating that 6-year-olds tend not to organize meanings bipolarly. Experiment 2 showed that the disruptive effects of incongruence on new learning disappears by college age. 相似文献

The present study examined the effectiveness of two components (rehearsal training and strategy awareness) of an instructional package designed to train the developmentally young in the use of mature information processing techniques. Two groups of children of equivalent developmental age (MA = 8), one mildly retarded and the other of average intelligence, participated. Rehearsal training was effective in improving recall scores on the training task; however, neither rehearsal training, memory awareness, nor their combination significantly altered memory performance on the generalization tasks. There was evidence, however, that the combination of rehearsal training and strategy awareness did increase the likelihood of strategy transfer on the generalization task (recognition) which most closely resembled the training task. Post-task questioning revealed that instructions concerning memory awareness did improve subjects ability to verbalize appropriate strategic behavior; however, these improvements were not consistently translated into either actual use of a rehearsal strategy or improved performance. Discussion centered on the implications of these results and on the need for increased research on the metamnemonic skills involved in strategy generalization. 相似文献

The threshold of a brief signal temporally centered in a noise masker first increases and then decreases as the masker is increased in duration. We discuss two explanations for this “over-shoot” phenomenon which consider the role of peaks of an exponentially weighted sliding integrator. One such explanation takes into account the finding that the steepness of the psychometric function continues to increase monotonically as its location moves first right and then left. 相似文献

In a study designed to assess the relationship between smoking status and correct identification of cigarette brands, junior high school students from two schools viewed cigarette and automobile advertisements with brand and model identification deleted. Results showed that adolescents with higher ad recognition scores were more likely to smoke cigarettes. In addition, a relationship was found between age and correct identification of cigarette advertisements, with older students identifying more ads correctly than younger students. No significant effects emerged for identification of automobile advertisements except for sex, with boys identifying more advertisements than girls. Additional findings indicated that even “experimental” smokers, who smoked as little as once per year, recognized significantly more cigarette advertisements than nonsmokers. These and other results are discussed in terms of their implications for prevention and policy issues. It is argued that society's allowance of printed cigarette advertising overlooks adolescents' heightened vulnerability to the kinds of appeals used in cigarette advertisements. Present policy also overlooks adolescents' relative unresponsiveness to the health risk information required in cigarette advertisements. 相似文献

Perceptual organization and focused attention: the role of objects and proximity in visual processing. 总被引:5,自引:0,他引:5
The influence of the Gestalt grouping principles of similarity, closure, and proximity on the size of the response-compatibility effect was examined in a focused attention task. In three studies, subjects responded to a centrally located target and attempted to ignore adjacent distractors. The distractors, which served as targets on other trials, could be compatible, incompatible, or neutral with respect to the response of the target. In addition, the distractors and the target could be embedded in the same object, presented in the same color, presented on different objects, or presented in different colors. The typical response-compatibility effect (B. A. Eriksen & C. W. Eriksen, 1974) was found when the target and distractors were embedded in the same object or presented in the same color. Performance was poorer when the target was surrounded by response-incompatible distractors than when it was surrounded by response-compatible distractors. However, the response-compatibility effect was eliminated when the target and distractors were embedded in different objects, even when the distance between the items was less than .25 degrees of visual angle. Furthermore, the response-compatibility effect was of intermediate size when the distractors were not grouped strongly with the target or with neutral flankers. The results are discussed in terms of space- and object-based models of visual attention. 相似文献

Our original goal was to explore the nature of the grouping-by-movement phenomenon reported by Driver and Baylis (1989). In their studies, distractors that moved in common with a centrally located target had a larger influence on focused-attention performance than did more proximate but stationary distractors. These results seemed particularly important since they suggested, contrary to the predictions of space-based models of attention, that attention could be allocated to noncontiguous regions of the visual field. Their results also suggested mandatory processing of stimuli with common motion. Unfortunately, we were unable to replicate this grouping-by-movement effect. In the conditions of Experiment 1 in which we replicated Driver and Baylis’s methodology, stationary distractors produced a larger response-compatibility effect than did the more distant distractors that moved in common with the target. In Experiment 2, we redundantly coded the centrally located target and the far distractors with common movement and color. However, the results were identical to those obtained in Experiment J. The stationary near distractors that appeared in a different color from the target and the far distractors produced the largest response-compatibility effect. In a final experiment, we attempted to compensate for the reduced acuity of the moving distractors by adjusting their size by a cortical magnification factor. However, even with this manipulation, we found a larger response-compatibility effect for the stationary near distractors than for the moving distant distractors. Our results suggest that subjects are capable of selectively processing a target item that moves in common with distractors. 相似文献

This work advances an interdependence theoretic analysis of the role of self-respect in ongoing close relationships. Self-respect is defined as the tendency to perceive the self as a principled person who is worthy of honor and high regard and is argued to rest on moral integrity. Consistent with predictions, results from a study of marital relationships revealed that individual self-respect is positively associated with both the individual's and the partner's pro-relationship behavior (accommodation, forgiveness, conciliation). Mediation analyses revealed that self-respect not only exhibits direct associations with each person's behavior, but also exhibits indirect associations with each person's behavior, via the impact of each person's actions on reciprocal pro-relationship behavior from the partner. Mediation was more reliably observed for the association of self-respect with partner behavior than for the association with individual behavior. Both individual pro-relationship behavior and partner pro-relationship behavior are positively associated with couple well-being, which in turn is positively associated with personal well-being (life satisfaction, physical health, psychological adjustment). These associations were evident in both within-participant and across-partner analyses and for both self-report and interaction-based measures of behavior. Self-respect reliably accounts for unique variance beyond variance attributable to self-esteem. 相似文献

Dealing with betrayal in close relationships: does commitment promote forgiveness? 总被引:10,自引:0,他引:10

This work complements existing research regarding the forgiveness process by highlighting the role of commitment in motivating forgiveness. On the basis of an interdependence-theoretic analysis, the authors suggest that (a) victims' self-oriented reactions to betrayal are antithetical to forgiveness, favoring impulses such as grudge and vengeance, and (b) forgiveness rests on prorelationship motivation, one cause of which is strong commitment. A priming experiment, a cross-sectional survey study, and an interaction record study revealed evidence of associations (or causal effects) of commitment with forgiveness. The commitment-forgiveness association appeared to rest on intent to persist rather than long-term orientation or psychological attachment. In addition, the commitment-forgiveness association was mediated by cognitive interpretations of betrayal incidents; evidence for mediation by emotional reactions was inconsistent. 相似文献

A limitation of a simple linear mass-spring model in describing goal directed movements is that it generates rather slow movements when the parameters are kept within a realistic range. Does this imply that the control of fast movements cannot be approximated by a linear system? In servo-control theory, it has been proposed that an optimal controller should control movement velocity in addition to position. Instead of explicitly controlling the velocity, we propose to modify a simple linear mass-spring model. We replaced the damping relative to the environment (absolute damping) with damping with respect to the velocity of the equilibrium point (relative damping). This gives the limb a tendency to move as fast as the equilibrium point. We show that such extremely simple models can generate rapid single-joint movements. The resulting maximal movement velocities were almost equal to those of the equilibrium point, which provides a simple mechanism for the control of movement speed. We further show that peculiar experimental results, such as an 'N-shaped' equilibrium trajectory and the difficulties to measure damping in dynamic conditions, may result from fitting a model with absolute damping where one with relative damping would be more appropriate. Finally, we show that the model with relative damping can be used to model subtle differences between multi-joint interceptions. The model with relative damping fits the data much better than a version of the model with absolute damping. 相似文献
