Age differences in peripheral perceptual processing: a monoptic backward masking investigation 总被引:1,自引:0,他引:1
D A Walsh R E Till M V Williams 《Journal of experimental psychology. Human perception and performance》1978,4(2):232-243
Peripheral processes in vision were investigated in two experiments involving monoptic backward masking with random noise. For young and old subjects, peripheral processing time (represented by stimulus onset asynchrony of target and mask) was characterized as a power function of target energy. Although processing time for both age groups showed a similar rate of decline with increasing target energy, old subjects processed targets more slowly at all energy levels. Results were independent of education, sex, and criterion differences between young and old. Target duration was related to critical interstimulus interval, such that stimulus onset asynchrony between target and mask was approximately constant for a given target energy within each age group. Evidence suggests that peripheral processing begins with target onset and that processing time is best characterized by a power function relating stimulus onset asynchrony of target and mask to target energy. 相似文献

Using either a gas chromatography or an infrared absorption technique, series of blood alcohol concentrations (BACs) determined by breath tests were obtained from human subjects immediately subsequent to their having only oral contact with beverages ranging in ethyl alcohol concentration from 4% to 95% +. Times for total dissipation of mouth alcohol residuals to a level of practical nonsignificance ranged from 10 to 19 min. Dissipation rates were an inverse and approximately exponential function of the ethyl alcohol concentration of the beverage and were greatly shortened by rinsing the mouth with warm (34°C) water prior to testing. The results are discussed in terms of their relevance to the methodology of a number of research studies employing BAC breath-testing equipment. 相似文献

This paper describes a newly available microcomputer system for the on-line administration, scoring, and interpretation of psychological tests. User response to the system is reported. Results of a validity study of the system’s Minnesota Multiphasic Personality Inventory interpretative program are presented. 相似文献

An on-line assessment system is briefly described. Previous positive evaluation studies are summarized. Results of studies of staff acceptance and staff preparedness for change are reported. Findings are interpreted in terms of the need for planning for change. Implications related to the acceptance of other on-line computer systems in psychology are discussed. 相似文献

In order to determine what variables contribute to or detract from the inter- personal attraction of a successful career woman, 80 male and 80 female introductory psychology students at a large western state university viewed one of eight different videotapes of a female stimulus person discussing aspects of her career and homelife. Two levels of occupation (traditional vs. nontraditional), two levels of competcnce (high vs. low), and two levels of role overload (high vs. low) were factorially varied for each videotape. The Attitudes toward Women Scale (AWS) was used as a covariate, thereby equalizing attitudes between the sexes. A multivariate analysis of covariance was performed on the data. Results indicated that all main effects-competence, role overload, occupation, and sex of subjects-were significant. Also significant was a sex of subject by occupation interaction and two three-way interactions. These results were discussed in the context of how they increase our understanding of college students' perceptions of successful career women. 相似文献

This study was concerned with the qualitative differences in the male and female sex-trait stereotypes. Previous research employing the item pool of the Adjective Check List (ACL) had indicated no relationship between the stereotype loading of the adjectives and their favorability ratings. In the present study, university students rated the ACL items for strength and activity, and these ratings were used to demonstrate that the male stereotype was appreciably stronger and more active than the female stereotype. It was found that the strength ratings were highly correlated with both activity and favorability ratings which were, themselves, unrelated. It was concluded that the principal qualitative difference between the stereotypes lay in the connotations of activity and passivity associated, respectively, with the male and female stereotype traits, and that any assertion of greater social desirability for the male stereotype was based on its greater activity and not, as is often supposed, on its greater favorability. 相似文献

Summary A modified Brown-Peterson paradigm was employed to determine the extent to which proactive interference effects of a sensory nature would influence the occurrence of sensory encoding specificity effects in episodic memory. Subjects presented with an auditory or a visual study list of five to-be-remembered (TBR) words engaged in either an auditory or a visual arithmetic distractor task for 30 s, and then received the first word in the study list as an auditory or visual intralist retrieval cue or received no cue. Presentation of the intralist retrieval cue in the modality of the study list enhanced the effectiveness of the retrieval cue, whereas presentation of the retrieval cue in the modality of the distractor task decreased the effectiveness of the retrieval cue. Sensory encoding specificity effects were largest when the distractor task occurred in the modality opposite to the modality in which both the study list and the retrieval cue were presented. 相似文献

A study was carried out during the early stages of the introduction of a career development scheme in a large government department. Information relating to aspects of various careers counselling issues was gathered from staff who had received such counselling and from personnel staff responsible for its provision. The study shows, amongst other things, that the interviewers were perceived to use some counselling skills, that the interviewers claimed they experienced few problems of role conflict, but that the staff tended to identify the interviewers with management. The findings are discussed relation to the appropriateness of interviewing style and to the broader context of how individuals might influence their career development within the opportunities provided by the organisation. 相似文献

This experiment investigated Allport's (1977) claim that normal subjects can be induced to make semantic errors of the type characterised by “deep dyslexia”. The procedure followed that used by Allport except that a subject based control for the chance level of semantic errors was included. The results replicated the original finding by producing a semantic error rate of 12·7%. It was shown, however, that this rate was not significantly higher than the calculated chance rate of 11·5%. It was concluded, therefore, that the semantic error rates reported by Allport can be accounted for in terms of a guessing artefact and thus they bear no relevance to the problem of deep dyslexia. 相似文献
