The question has been raised whether an associative mechanism is responsible for the persistence of the McCollough effect. Since current estimates of its rate of decay are derived from procedures in which subjects are repeatedly tested, it was hypothesized that the measured effects might be attenuated by the testing process. Accordingly, a comparison was made between repeated testing and time-elapse testing. A conventional group of 16 subjects had repeated testing at 0, 8, 24, 56, and 120 hr. after induction. Five other groups of 16 were run, each at one of the time delays, with no intervening tests; an additional measure was taken where appropriate at 120 hr. A magenta-green nulling procedure was used to assess the aftereffect. The repeated-test group showed a linear decrease of effect against the stated delays, reaching zero at 120 hr. In contrast, the time-elapse groups showed little decline up to 120 hr. Those groups retested at 120 hr. showed declines due to prior testing. When four more groups were subsequently tested at intervals up to 2,040 hr., the effect remained at better than half strength. 相似文献

A standard speaker read linguistically confident and doubtful texts in a confident or doubtful voice. A computer-based acoustic analysis of the four tapes showed that paralinguistic confidence was expressed by increased loudness of voice, rapid rate of speech, and infrequent, short pauses. Under some conditions, higher pitch levels and greater pitch and energy fluctuations in the voice were related to paralinguistic confidence. In a 2 × 2 design, observers perceived and used these cues to attribute confidence and related personality traits to the speaker. Both text and voice cues are related to confidence ratings; in addition, the two types of cue are related to differing personality attributes. 相似文献

A comparison was made between two measures of somatosensory sensitivity, response probability, and reaction time to electrocutaneous constant current pulses of 350-microsec duration. The psychometric functions are steeper than those obtained for other sensory modalities. Similarly, the reaction-time/intensity functions are also steeper than those obtained in other modalities, i.e., larger decreases in reaction time as a function of small increases in stimulus intensity. Ss exposed to a broad stimulus range, including high intensities, yield psychometric and reaction time functions displaced into a higher intensity region than when they are exposed to a narrow low-intensity range of stimuli. The data are discussed in terms of a decision-theory model of reaction time. 相似文献

The potential of Holland's theory for use in the vocational guidance of adult women depends in part on more validity data with regard to the conceptual meaningfulness of the constructs. This study reports the findings of a correlative analysis between scores on Holland's Vocational Preference Inventory (VPI), which measures the six “styles”, and selected scales on four criterion tests predicted in advance to be related to the VPI. The findings for this sample of adult women indicate strong evidence for the validity of the Intellectual, Conventional and Enterprising “styles”, but questions are raised with regard to the meaningfulness of the Realistic, Social, and Artistic types. 相似文献

Existing marital counseling procedures have not been experimentally evaluated or generally have not been based on an experimentally derived theory. The present study formulated a model of marital discord based on reinforcement theory, developed a marital counseling procedure based on that theory and experimentally evaluated its effectiveness. The model viewed marital discord as the resultant of non-reciprocated reinforcement. The counseling procedures attempted to establish general marital reciprocity of reinforcement by teaching reciprocity in several specific areas of marital unhappiness. The reciprocity procedure was conducted for about 3–4 weeks with 12 couples, after first conducting a catharsis-type counseling as a control procedure. The results showed that the reciprocity procedure increased reported marital happiness, whereas the control procedure did not. Once reciprocity was achieved in a specific problem area, the benefits generalized somewhat to other yet-to-be counseled areas. The increase in marital happiness occurred for each of the specific areas of marital interaction, for 96 per cent of the clients, and was maintained and increased during the available follow-up period. These results indicate that the procedure is an effective, rapid and enduring method of producing marital happiness. 相似文献

Two experiments were conducted to investigate possible determinants of perceived choice. The first experiment employed an observer paradigm and the second employed an actor paradigm. The results of both studies provided evidence for the hypotheses that perceived choice will be greater when there is a small difference in attractiveness between outcome alternatives than when there is a large difference and under conditions of low certainty about the attractiveness of each outcome alternative than under conditions of high certainty. Also, the results of both studies provided some evidence for the hypothesis that the effect of the relative difference in attractiveness upon perceived choice will be greater under conditions of low certainty than under conditions of high certainty. The hypothesis that perceived choice will be less when there is no difference in attractiveness between outcome alternatives than when there is a small difference was not supported by the results of the first experiment but was supported by the results of the second experiment. The hypothesis that perceived choice will be greater the more time a person takes to select an action from possible actions was supported by results of the first experiment but not by those of the second experiment. The results for the relative difference and certainty variables were discussed in terms of a theoretical analysis of perceived choice. 相似文献
