The effects of a self-instructional package on three overactive preschool boys were investigated using a multiple-baseline design across subjects. Behavioral observations of the three target subjects indicated transfer of training effects from the experimental tasks to the classroom. On-task behaviors increased dramatically concomitant with the introduction of the self-instructional package, and treatment gains were maintained 22.5 weeks after baseline was initiated. In addition, the use of an observer-expectancy control condition gave further credibility to the demonstration of a causal relationship.  相似文献

The effects of a social skill training program on socially isolated children are reported. The training program was derived from the results of a previous study of the specific social skills that discriminated popular from unpopular children. Training effects in the present investigation were assessed on sociometric position, and on the quality, frequency, and distribution of social interaction to peers. Time-series analyses were performed on the frequency and distribution of peer interaction. Two isolated children received social skill training with an adult coach, and two isolated children spent an equivalent amount of time with an adult. Results indicated that socially isolated children in the treatment group changed significantly in sociometric position on a follow-up assessment 9 weeks after the end of the intervention, did not change in the total frequency of peer social interaction, but did redistribute their interaction to peers. The two isolated children who did not receive the treatment program did not change significantly on the total frequency of peer interaction, and tended to withdraw from peers rather than redistribute their interaction. The insensitivity of total peer interaction frequency as a measure of outcome was discussed.  相似文献

Report of single letters from centrally-fixated, seven-letter, target rows was probed by either auditory or visual cues. The target rows were presented for 100 ms, and the report cues were single digits which indicated the spatial location of a letter. In three separate experiments, report was always better with the auditory cues. The advantage for the auditory cues was maintained both when target rows were masked by a patterned stimulus and when the auditory cues were presented 500 ms later than comparable visual cues. The results indicate that visual cues produce modality-specific interference which operates at a level of processing beyond iconic representation.  相似文献

Initial increases in the availability of items for report following tachistoscopic presentation of centrally-fixated rows of seven random letters were directly evaluated by measuring report accuracy following exposure durations of 10, 20, 40, 80 and 160 ms. A partial-report technique was used, and each presentation of a letter row was immediately followed by the presentation of a masking stimulus. Each of 10 subjects received 840 trials which reflected 24 trials for each exposure-duration by position-probed combination. The letters at both ends of a row became available for report prior to the centre letters. In addition, report of the left-most letter was consistently better than report of the right-most letter, and report of the centre item at fixation improved at a more rapid rate with increased exposure duration than report of the other centre letters. This pattern of results provides support for certain components of several different previous proposals concerning the order in which individual items from multi-element displays become available for report.  相似文献

Two experiments investigating the selective adaptation of vowels examined changes in listeners’ identification functions for the vowel continuum [i-I-∈] as a function of the adapting stimulus. In Experiment I, the adapting stimuli were [i], [I], and [∈]. Both the [i] and [∈] stimuli produced significant shifts in the neighboringand distant phonetic boundaries, whereas [I] did not result in any adaptation effects. In order to explore the phonetic nature of feature adaptation in vowels, a second experiment was conducted using the adapting stimuli [gig] and [g ∈ g], which differed acoustically from the [i] and [∈] vowels on the identification continuum. Only [gig] yielded reliable adaptation effects. The results of these experiments were interpreted as suggesting arelative rather than a stableauditory mode of feature analysis in vowels and a possibly more complex auditory feature analysis for the vowel [i].  相似文献

Investigated the effects of fear arousal and sidedness variables on compliance with a dietary regimen. Experiments involved 202 women volunteers who were 10 per cent or more overweight, and aged 20-60 years. Experiment 1 involved a 3 (low, medium, high fear) × 2 (single, multiple exposure to fear message) × 2 (one-, two-sided communication) design. The fear levels involved discussing the health hazards of obesity. Experiment 2 manipulated the fear-message position relative to the recommendations (fear-recommendations, recommendations-fear, fear-delay-recommendations). Persuasive impact was measured via follow-up weight checks at 2, 4, 8, and 16 weeks. Results indicate nonsignificant effects from sidedness and pre-standardised fear levels. Using subjects' fear arousal ratings medium fear is significantly better (p < .025), supporting Janis's curvilinear hypothesis. A single exposure to the fear message is superior (p < .025) to multiple exposures, the interaction with time being highly significant (p < .001). Experiment 2 results indicate the optimum position for the fear message as immediately prior to recommendations (p < .025). Results support both cognitive and fear-reduction hypotheses, but the latter is favoured.  相似文献

ABSTRACT Only a minority of those who experience shyness consider themselves to be shy people One explanation for this lies in the possibility that those who so label themselves underestimate the extent to which their feelings are shared by others (i.e, perceive the consensus surrounding their experiences as low [Kelley, 1967]), resulting in an internal rather than external attribution This proposition was tested by asking shy and not-shy followers of two TV soap operas to rate a number of characters from the programs, together with a list of their friends and relatives, for shyness, competitiveness, and optimism Although there were no differences between the groups in their ratings of competitiveness and optimism, the shy subjects reported greater shyness among both the soap-opera characters and their friends and relatives than the not-shy group Whatever the basis for the self-labeling of shyness, therefore, it does not appear to he in the low consensus/pluralistic ignorance notion A number of alternative explanations are discussed, together with the implications of these findings for explanations of the false consensus effect  相似文献

In the present paper, we describe the software and hardware of an on-line, visual-memory laboratory running under Turbo Pascal on an IBM PC XT-compatible computer. The display system includes one Kodak random access projector and four standard Kodak carousel projectors, all equipped with tachistoscopic shutters and luminance-control devices. The response system consists of eight 16-key response boxes. The laboratory can be used for any experiment in which 35-mm slides are to be used as stimuli, and in which precise display times, stimulus luminances, and reaction times are required. The laboratory is particularly well suited to picture-perception and picture-memory experiments.  相似文献

The concepts of locus of control, self-concept, masculinity-femininity, and their relationship to fear of success in Black college women were explored. Scores were obtained from stories written in response to six verbal cues designed to assess fear-of-success imagery. Tabulations ranging from zero (denoting absence of fear) to six (denoting most fear) were correlated with Gurin's I-E Scale, the Modified Piers-Harris Self-Concept Scale, and the Modified Gough Masculinity-Femininity Scale. There was no significant mean difference between freshmen and seniors on fear of success. However, an analysis of variance revealed that externals showed significantly more fear-of-success imagery than internals. Significant inverse correlations were located between the measure of self-concept and certain cues eliciting fear of success. Femininity was not shown to be related to any of the fear-of-success measures.  相似文献
