Observers classified sine-wave and square-wave gratings on the basis of fundamental frequency (Are the bars wide or narrow?) or on the basis of higher harmonic frequencies (Are the bars sharp or fuzzy?). Stimuli were presented in either the left (LVF) or right (RVF) visual field. When the classification was made on the basis of the fundamental frequencies (1 or 3 c/deg), there was a LVF/right hemisphere advantage. However, when the classification was on the basis of a sharp/fuzzy distinction which involved searching for the higher harmonic frequencies, then a RVF/left hemisphere advantage was found. 相似文献

On the Relation Between Time Perception and the Timing of Motor Action: Evidence for a Temporal Oscillator Controlling the Timing of Movement 总被引:7,自引:0,他引:7
Michel Treisman Andrew Faulkner Peter L. N. Naish 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1992,45(2):235-263
Studies of time estimation have provided evidence that human time perception is determined by an internal clock containing a temporal oscillator and have also provided estimates of the frequency of this oscillator (Treisman, Faulkner, Naish, & Brogan, 1992; Treisman & Brogan, 1992). These estimates were based on the observation that when the intervals to be estimated are accompanied by auditory clicks that recur at certain critical rates, perturbations in time estimation occur. To test the hypothesis that the mechanisms that underlie the perception of time and those that control the timing of motor performance are similar, analogous experiments were performed on motor timing, with the object of seeing whether evidence for a clock would be obtained and if so whether its properties resemble those of the time perception clock. The prediction was made that perturbations in motor timing would be seen at the same or similar critical auditory click rates. The experiments examined choice reaction time and typing. The results support the hypothesis that a temporal oscillator paces motor performance and that this oscillator is similar to the oscillator underlying time perception. They also provide an estimate of the characteristic frequency of the oscillator. 相似文献

Traditionally, communication skills training has focused principally on overt behaviours that are clearly identifiable. In recent years there has been an increasing awareness that cognitive processes can have considerable influence on behaviour. An attempt was made to establish whether changes in cognitions occurred as a result of a behaviourally-based communication skills training programme in which there had been no explicit attempt to bring about such cognitive changes. More specifically, the study examined whether such a programme resulted in changes in aspects of the personal construct space of students on a Diploma in Careers Guidance course. The results offered some support for the hypothesis that the programme produced changes in the students' personal construct space. 相似文献

Gender differences in children's play activities, preferred school subjects, and occupational goals were examined in relation to such parental variables as toy-giving and chore assignment. Subjects were 245 children in grades K, 3, 6, and 8. Subjects completed questionnaires before and after Christmas asking what gifts they wanted, asked for, received, and liked best. They also were asked to name their friends and play activities, favorite and least-liked school subjects, occupational aspirations, and chores at home. Children generally wanted, asked for, received, and most-liked gender-typical toys. They were less likely to receive requested gender-atypical toys. Children's preferred activities, job aspirations and assigned chores were along gender-typical lines. Girls preferred masculine toys and jobs more than boys preferred feminine ones. With increasing age, both girls and boys increasingly preferred masculine toys and male friends. No gender differences in favorite or least-liked school subjects were found. School subject preference was related to gender-typing of occupational choice for girls but not boys.An earlier version of this paper was presented at the annual meeting of the American Psychological Association, Anaheim, California, 1983. 相似文献

The essential activity of group therapy consists of members taking an interest in each other by asking questions, showing concern, and conveying understanding. When members have not done this it has often been taken as a sign of resistance. A review of the research on helping suggests that there are four social factors that affect assistance giving in groups: 1) ambiguity-often people fail to give help because they are uncertain about who should give it, what should be done, and how it should be done; 2) often help is not given because of the way in which problems are presented; 3) the social comparisons that individuals make affect help-giving; and 4) there are costs associated with providing assistance. This discussion suggests that leaders can facilitate interaction among group members as teachers who clarify and as indirect helpers who redirect concerns back to group members. 相似文献

This study explored patterns emerging in videotaped sessions of group psychotherapy with seven outpatients of a large mental health facility. The 22 sessions spanned the 12th to 27th months of the group's existence. Group members had long histories (25–50 years) of symptoms characteristic of schizophrenia. Each session was rated on the Group Environment Scale. One session from a group in its earlier stages was also rated on the same instrument to give some indication of baseline patterns. Analyses of changes across the 15 months were not statistically significant. However, some GES subscales, including Cohesion, Independence, and Self-Discovery, showed relatively high mean levels across the 15-month period. These elevations are discussed as suggesting the codevelopment of orientations that have sometimes been viewed as incompatible and unattainable for schizophrenics. Interpreted clinically, the GES patterns help to elaborate recent findings about the relatively good success of long-term group therapy with such populations. The study, although merely suggestive, illustrates the potential for gleaning solid and clinically useful data from group psychotherapy research.The authors would like to thank Drs. Jill Rierdan, Nina Fieldsteel, Joseph Christy, and an anonymous reviewer for their suggestions, Kendra Bryant for serving as the reliability rater, and Janet Eltinge for her skilled videotaping. 相似文献

Eighty younger (less than 50 years, M = 28 years) and 80 older (more than 50 years, M = 69 years) Type A and Type B Ss were evaluated for Type A behavior pattern using the Structured Interview (SI) and given personality tests for anxiety, depression, anger, aggression, hostility, and anger-in-anger-out. Ss also underwent an emotion induction procedure. Videotapes of the emotion induction procedure (N = 160) and the SI (N = 80) were coded for facial expression of emotion. Type As did not differ from Bs on anxiety or depression but did on anger and aggression. Type As showed anger inhibition and anger bound to shame, as predicted by emotion socialization theory. The greatest number of differential effects were observed between age groups. Older individuals, in general, were more emotionally expressive than younger Ss across a range of emotions. Women appeared more conflicted about anger expression than men, and Type A women more so than Type A men. 相似文献

The Treatment Evaluation Inventory (TEI), a frequently used measure of treatment acceptability, was used by 164 undergraduates to rate the acceptability of each of the following treatments: differential reinforcement of other behavior, exclusionary time-out, overcorrection, medical restraint, contingent electric shock, and physical restraint. TEI ratings of each treatment type were grouped separately, variance-covariance matrices were formed and compared, and data were subjected to factor analysis. The results indicated that the factor structure of the TEI varied with the treatment it was used to evaluate. Item analysis of the TEI indicated a high degree of internal consistency, although item-total correlations varied between rated treatments. The findings suggest that although the TEI is a reliable instrument, sensitive assessment of the treatment acceptability construct probably requires multidimensional measurement. 相似文献

Older adults' life satisfaction can be better understood in light of their personal goals. This study of 179 elders examined (a) how goals correlate with satisfaction, (b) whether elders maintain satisfaction by accommodating goals to past losses, and (c) how correlations between satisfaction and key predictors differ among groups with different goals. Satisfaction was related positively to social maintenance and energetic life-style goals and negatively to concerns for improvement, disengagement, stability, and reduced activity. Past losses were correlated with current goals but not with satisfaction, consistent with the notion of accommodation. A cluster analysis identified 5 patterns of goals: high demand, age prescribed, self-focused, socially engaged, and low demand. Correlations between satisfaction and other predictors differed by cluster, suggesting that the determinants of elders' satisfaction depend on personal goals. 相似文献
