Rats received runway training under alternating reward and nonreward in which rewarded (R) trials provided 32 or 4% sucrose concentration from a drinking tube and nonrewarded (N) trials provided a dry tube or, for half of the rats in the 32% condition, plain water. Both 32 and 4% concentrations yielded faster running on R trials than on N trials; but this effect was reliable only for the 32% condition. Compared to 4% sucrose, 32% sucrose yielded reliably slower running on N trials and unreliably faster running on R trials. 相似文献

The Minnesota Job Requirements Questionnaire (MJRQ) was developed and administered to supervisors of 11 selected jobs who rated the ability requirements of the job they supervised. The MJRQ represented each of nine GATB aptitudes by five items in a Likert-type format. MJRQ ratings were compared with expert ratings in the Dictionary of Occupational Titles (DOT) and Occupational Ability Patterns (OAPs) derived from administration of the General Aptitude Test Battery (GATB). Reliability of MJRQ ratings was shown by high Hoyt reliability coefficients. Comparison of mean ratings and variabilities of ratings by supervisors in a job showed construct validity for the MJRQ approach, as did intercorrelations of MJRQ ratings. OAPs derived from the MJRQ compared favorably with those derived from the GATB and DOT, showing promise for the parsimonious MJRQ approach to the development of OAPs. 相似文献

An examination of two judgement models, adaptation-level (AL) theory and the theory of signal detection (TSD), was made in terms of their ability to handle data from several voluntary generalization studies. Both models were found to be somewhat inadequate, though in different ways. AL theory was found to be unable to predict amount or slope of the generalization gradient, while TSD was seen to be unable to account for shifts in judgment due to context and frequency effects. A combined AL-TSD model was presented which combines the advantages of each model and offers a good account of both choice and latency data in voluntary generalization 相似文献

A 2-year follow-up study of public vocational school graduates revealed that the graduates successfully obtained jobs. Among the factors deemed important by both graduates and employer, communication skills were mentioned as vital. Counseling and preparation in getting along with others were perceived by graduates as inferior. Except for cooperative work program graduates, adjustment to an 8 hr workday caused some problems. 相似文献

Coding strategies and cerebral laterality effects 总被引:1,自引:0,他引:1
In a short-term recognition memory task, Ss were given relational imagery and rehearsal coding strategies in different sessions, with probes presented to the left or right cerebral hemisphere. Consistent with a model of separate processing systems for verbally and visually coded information, Ss yielded significantly faster response latencies for probes to the left hemisphere than the right when employing the rehearsal strategy, and significantly faster latencies for probes to the right hemisphere than the left when using the imagery code. This suggests that cerebral laterality effects are functionally related to coding strategies, and argues for the inclusion of imagery, or generated visual information, as part of the visual processing system. As such, generated visual information may be viewed as a coding alternative to verbal mediation. 相似文献

It is easier to decide which of two letters was presented tachistoscopically if the critical letter was in a word rather than in a scrambled word. We showed that this word-superiority effect holds just as strongly for pronounceable nonwords as for words, even when the critical letters are constant over all trials. This finding rules out word meaning and familiarity as variables accounting for the effect. In addition, it was found that the superiority of pronounceable stimuli holds for two-letter stimuli as well as four, and it is therefore concluded that the effect is not due to a memory limitation. An explanation of the effect in terms of the use of additional acoustic information is ruled out by showing that the effect was not diminished when the two possible words sounded exactly alike. An experiment using correctly and incorrectly spelled chemical formulas suggested that spelling regularities, regardless of pronounceability per se, account for the superiority effect. Finally, when decisions about two critical letters must be made on each trial, the correlation between being correct on one and on the other is higher for pronounceable stimuli under some conditions. 相似文献

Sixty-nine second grade suburban children were rated by three teachers using a classroom behavior inventory. Factor analysis was performed to test the a priori structure of the instrument. The 18-item inventory was analyzed on three factors: Task-Oriented vs Distractibility, Extroversion vs Introversion, and Considerateness vs Hostility. The three factors loaded perfectly according to the a priori design. The need for further investigations concerning the reliability and a comparison of the rating scale with objective observations is indicated. 相似文献

A recent experiment by Messick and Reeder (Journal of Experimental Social Psychology, 1972, 18, 482–491) attempted to extend Jones, Davis, and Gergen's (Journal of Abnormal and Social Psychology, 1961, 63, 302–310) classic finding that out-of-role behavior.is more informative for person perception than in-role behavior. It is argued, however, that this study confounded two variables, role performance and occupation. Evidence is presented that the occupation variable alone could have produced Messick and Reeder's results. Both variables seem to affect attributions. The importance of these findings for relating attribution theory and role theory is discussed. 相似文献

A subject was induced to publically report his opinions on a variety of issues. A group of confederates disagreed with the subject; one confederate agreed with him. Thus, the subject deviated from the majority of the group, but received social support from one other individual. Each subject was then paired with one individual from the previous group, and regardless of his pairing, was subjected to a constant amount of conformity pressure from the confederate on a new set of judgments. Deviant subjects conformed more to the confederate who had previously given them social support than they did to a previous majority member. This increased conformity was found in two studies, (1) females judging physical realities and, (2) males reporting their opinions on attitudinal issues. Ratings taken in the second study demonstrated that the deviant subject felt increased liking for and similarity to the confederate who initially provided him with social support, but comparisons between various experimental groups indicated conformity to a confederate was not completely predictable from the subject's liking for that confederate. Instead, conformity was greatest following an experience of deviation from the majority. 相似文献
