A model for memory scanning is proposed in which the encoded representation of a probe is compared in parallel with encoded representations of each item in the positive set. The within item matches are serial feature by feature comparisons that terminate when either a positive or negative criterion is reached. This model is shown to predict the results of a probe similarity experiment. The serial location of a similarity within an item affects negative reaction times, but the number of items in the positive set to which the probe is similar has no main effect. The model is also shown to yield predictions consonant with existing data on the relation between reaction times and set size and speed-accuracy trade offs. 相似文献

The major purpose of this study was to investigate whether favoritism for the physically attractive, a phenomenom demonstrated amost exclusively on the basis of rating scales, generalizes to nonreactive, behavioral helping responses. Four hundred and forty-two males and 162 female white adult callers in public phone booths in a large metropolitan airport found a completed graduate school application form, a photograph of the applicant, and an addressed, stamped envelope. The picture was used to convey information as to the physical attractiveness (attractive vs. unattractive), race (black vs. white), and sex of the applicant. As predicted, delivery of the application was facilitated more for attractive than unattractive persons. There was also a significant race effect, with whites receiving more help than blacks. Implications of these findings for the physical attractiveness literature are discussed. 相似文献

Second and sixth graders, ages 7–8 and 11–12, respectively, were presented with lists of pairs of nouns. They were asked to represent each pair in memory as a single interactive image, as two separate images, or by a control procedure. After presentation of the pairs, the children were tested either by cued or noncued recall. The difference between the interaction condition and the other conditions appeared in recall measures which reflect pairwise organization in memory (cued recall, pair recall, conditional recall probabilities, and χ2) to a much greater extent than in measures of individual item recall. The results were interpreted as supporting an imagery-organization hypothesis. 相似文献

A strong test of exposure effects was made by eliminating confounding demand characteristics through the use of a between-subject design. Each subject viewed novel stimuli at a single frequency level, and then rated them on several affective scales. Frequency of stimulus exposure was systematically varied across subjects. Stimuli were rated more positively with increasing exposure, despite the fact that subjects were unaware of any differences in exposure frequencies, and clearly unable to identify the experimental hypothesis. An awareness of the relationship between repeated exposure and affect was thus shown to be an unnecessary condition for the occurrence of exposure effects. 相似文献

Four experimental conflict situations having theoretical implications have been reported upon with some frequency. The purpose of this study was to compare individual differences on a common measure, response latency, in order to determine the stability of behavior across these four conflict situations using a comparable latency measure. The results of this study do indicate that behavior in experimental conflict studies shows a stability of performance by individual subjects. There are also group mean differences between the four procedures that reflect situational contribution to conflict behavior. 相似文献

One-hundred-and-sixty adolescents participated in two studies designed to investigate the relationship between and helping behavior as mediated by the perceived cause of another's need. In the first study, Ss were given the opportunity to help, either “indirectly” or “directly,” a supervisor who had been over- or underpaid in a prior similar task. Internals helped more in the “direct” help than the “indirect” help conditions but their helping behavior and their perceptions of their supervisors were not consistent. The perceptions of the externals were relatively consistent with their greater help of the “overpaid” supervisor. In study 2, the Ss were given additional information to increase the possibility of their making causal attributions as a function of the supervisor's prior fate. Once again, the external subjects' helping behavior reflected their perception of their supervisor's merit. The internal subjects exhibited relatively little helping behavior regardless of their supervisors' prior fate or perceived competence. 相似文献
