A token reinforcement program involving two levels of token value and backup reinforcers to increase journal reshelving behavior in a large university library was experimentally evaluated. Results showed that instructions (in which signs asked users to reshelve journals) had no impact. By contrast, token reinforcement contingent on reshelving behavior led to a marked increase in journals reshelved. A return to instructions-only conditions, when data were corrected for library usage, showed an increase in unreshelved journals over the token reinforcement period, though the increase was not to baseline levels. For the next 11 months, library staff maintained a modified token program. Follow-up data collected after that interval showed that number of unreshelved journals remained markedly lower than levels at baseline and the first instructions-only period, though they were slightly higher than at the token reinforcement period. Token reinforcement of the variety employed in this study constitutes an efficient, economical means of changing the behavior of library users who fail to reshelve books and journals. 相似文献

Kindergarten children were given simultaneous discrimination tasks with two irrelevant dimensions varying within settings. Prior to each block of eight feed-back trials, the children were asked to attempt to provide a statement of the solution. The introtacts thus provided were found to have several of the desirable characteristics that have been reported for older children with either introtact or blank-trial probes, but which have not been found previously for kindergarten children with the blank-trial probe. Classification of the children according to the trial block on which they first verbalized the correct relevant dimension was found to account for more than 60% of the total variability in discrimination performance. The introtacts were also used to assign parameters to theoretical prediction equations, with nearly two-thirds of the total variability in discrimination performance accounted for by the theory. Extension of the method to other models is discussed. 相似文献

The purpose of the present study was to test the hypothesis that memory for pictorial material is dependent on initial comprehension of the depicted relationships. Subjects at three age levels (second, sixth, and ninth grades) were compared on ability to remember cartoon pictures which did or did not contain action lines as clues to the interaction between actors. It was predicted that the older children, because of extensive experience with still cartoons and comics, would benefit from the action lines. The action lines facilitated recall of pictures for only the older students, specifically, the ninth graders. The object of the action was the most efficient probe, even though the action was more frequently remembered. These results are discussed in terms of the action (interaction) being the basis of comprehension and, consequently, the remembering of the picture. 相似文献

The relationship of personality variables to turnover and absenteeism was investigated using Cattell's 16 PF. Results indicated Factors G (conscientiousness) and Q4 (anxiety) accounted for most of the predictable variance in both indices or organizational withdrawal. The Porter and Steers "polar" hypotheses for organizational withdrawal were not confirmed except for the anxiety factor. Results are discussed in terms of Lyons'(1972) conclusions on the relationship of absenteeism and turnover and the generality of findings to other samples of employees. 相似文献

The fakability of an empirically keyed biographical inventory was studied in a three factor design. The factors were: 1. specificity of position applied for (sales representative versus a general managerial position, 2. induced subtlety of faking (warning of a lie scale versus no warning), and 3. sex of the respondent. Subjects were 91 male and 57 female college students who completed the biographical questionnaire under "fake" and "honest" response sets. Subjects were able to substantially improve their scores under faking instructions. Only the position specific-fake subtle condition failed to show improvement. Instructions indicating that a lie-detection scale might be used reduced faking to a considerable extent. Comparison with norms for the sales representative biographical key suggested that students in the faking condition tended to fake more than did a nation-wide sample of college recruits. 相似文献

One hundred college undergraduates were administered the Richardson revision of the Gordon Test of Visual Imagery Control, the Betts-Sheehan Questionnaire Upon Mental Imagery, and the Shipley-Hartford Institute of Living Scale. The latter provided a conceptual quotient (CQ) score of intellectual impairment based upon a ratio between vocabulary and abstraction scores. Subjects with CQs above 100 had significantly higher control scores (p less than .02). High control subjects had significantly higher total IQ scores than did low control subjects (p less than .04). Subjects with high and medium range control had higher vocabulary scores than those with low control. This suggests possible assessment of proneness toward introverted and extraverted neuroticism based upon a combination type of imagery score and the ratio between abstract or vocabulary scores. The connection of imagery with dimensions of IQ may be a start toward a more refined measure of this aspect of personality. Problems and implications are discussed. 相似文献
