The effects of embedding a constant time delay procedure into an independent seat work activity and using instructive feedback were evaluated in this study. Seven students with mild disabilities participated in the study that occurred in their special education classroom. A multiple probe design across sets of target behaviors was used, and students' responses to instructive feedback stimuli were evaluated during each probe condition. The procedures were implemented with a high degree of fidelity, and the results indicate that (a) the students acquired the target behaviors taught with the constant time delay procedure that was embedded into independent seat work, and (b) the students acquired some but not all of the responses to the instructive feedback stimuli. These findings are discussed in terms of using instructive feedback in classrooms and future research on instructive feedback.  相似文献

The current investigation examined the degree to which judges' ratings of skill, anxiety, and attractiveness are influenced by the responsivity of the confederate. High-, medium-, and low-skilled subject-pool groupings, as well as self-referred clinical groups, were exposed to either a moderately or a minimally responsive confederate. Results indicated that subjects were rated as more skillful when interacting with a moderately responsive confederate than when interacting with a minimally responsive confederate. Further, there was a groups × condition interaction for anxiety ratings such that both the high- and the medium-skilled groups appeared more anxious under the minimal condition, whereas the low-skilled and self-referred groups did not. Self-referred subjects received significantly lower attractiveness ratings than did the high- or medium-skilled groups. Implications of these results and future directions for research are discussed.This research is based on a M.S. thesis carried out by the first author under direction of the second author.  相似文献

Cornell University Medical College, Westchester Division, The New York Hospital, White Plains, New York It is well established that there is a complex timekeeping mechanism in the human brain. This mechanism is associated with a variety of physiological and psychological rhythms having a period of about a day, and thus referred to as circadian rhythms. The circadian system has recently been modeled in terms of two underlying oscillators, one much more resistant to changes in routine than the other. These oscillators are considered to be endogenous, that is, internal to the organism, and not reliant for their existence upon changes in the person’s environment or general behavior. They thus continue to run even when the sleep/wake cycle is suspended, as in sustained operations. Thus, by their very nature, sustained operations require the individual to override the inputs that are coming from his or her circadian system (especially the indication that sleep is required). The aim of this paper is to provide a background to the area of circadian rhythms research, including a section on the methodology, so that the impact of the circadian system on sustained operations can be better understood.  相似文献

Holland's theory of congruence of work environments was examined by analyzing the career redirection of 62 men of managerial and professional level who changed occupations between the ages of 33 and 54. Three-letter personality codes for each subject were obtained by administering the Strong-Campbell Interest Inventory. Dictionary of Occupational Titles codes for first and second occupation were obtained and then translated into Holland codes. These were compared to the personality code for each man to determine whether the first or second job was more congruent. It was found that 26 men changed to careers more congruent with their personality, 25 to careers less congruent, and 11 made no change. The results of the study do not lend support to Holland's theory, probably because of the imprecision of DOT categories for research purposes. The need for a more reliable means for coding work environments is discussed.  相似文献

Observer ratings of one-half hour interviews were undertaken to test two basic concepts of interpersonal relations in a sample of 51 randomly paired male psychiatric patients and female psychiatric nurses. It was hypothesized that the behavior of psychiatric patients could be organized around two orthogonal dimensions reflecting status and feeling, and that patients and nurses would exhibit complementary interpersonal behavior consistent with their institutionally ascribed roles. Interviews were rated with the Leary Interpersonal Checklist. Interjudge reliability was established for Leary's coding system. The hypothesis of status and feeling reference points for patient behavior received strong support when the results of analysis of variance were supplemented by factor analysis. Patient scores on the eight variables measured by the Leary Interperonsal Checklist and nurses' scores for 17 complementary variables were submitted to correlational analysis to test the hypothesis of interpersonal complementarity. As predicted, two hypothesized dependence-assistance response combinations provided the highest correlation coefficients. It was concluded that the study provided empirical support for the utility of an interpersonal model within psychiatric settings that has more commonly been identified with relationships free of psychiatric disturbance.  相似文献

An incidental memory paradigm was used to study involuntary encoding processes and voluntary retrieval strategies in children's memory. Preschool (mean age: 4 years, 4 months) and kindergarten (mean age: 5 years, 10 months) children sorted pictures according to their color or category membership, and then received either a recall test (Experiment 1) or a recognition test (Experiment 2). Better retention of category- than color-sorted items was observed for kindergarten children in free recall, preschool and kindergarten children in cued recall, and neither group in recognition. These results were interpreted in terms of the retrieval strategies used by children in each of the memory tasks. The importance of distinguishing between voluntary and involuntary memory processes, and between acquisition and retrieval, in studies of depth-of-processing was emphasized. Developmental differences in performance appear to derive primarily from the role of voluntary search strategies in retrieval, rather than from age differences in involuntary encoding processes.  相似文献

The basis for the invariant perception of place of articulation in pre- and postvocalic stops was investigated using the selective adaptation paradigm. Experiments 1 and 2 considered the role of identical bursts, mirror-image formant transitions, and similar onset and offset spectra in the invariant perception of place of articulation in CV and VC stimuli, and Experiment 3 considered the importance of the second two cues in a VCV context. The results of these experiments suggest that, at the level of processing tapped by selective adaptation, neither identical bursts, mirror-image formant transitions, nor similar onset and offset spectra are the basis for the invariant perception of place of articulation in initial and final position. The vowel portion of an adapter was found to affect perception of the consonant portion of a stimulus, and the direction of this effect was predictable from the acoustic characteristics of the consonant and vowel. The implications of these findings for the nature of selective adaptation are discussed.  相似文献

This study shows that sex is an important status variable in occupational settings. The basic hypothesis that males, because of a status prerogative, would be more likely than females to use nonverbal and verbal dominance behaviors, including intimate gestures, toward their opposite sex co-workers was confirmed. Subjects (88 female and 69 male samples from two institutions of higher learning) reported dominance behaviors (a) toward opposite sex co-workers; (b) from opposite sex co-workers; (c) toward opposite sex superiors; and (d) from opposite sex superiors. Analysis of the sexual dominance items revealed that sexual intimacy is expressable along the same continuum as traditional dominance gestures. The hypothesis that sex competes with other status variables was supported. If the sexual dominance patterns explored in this study prove widespread, institutions may wish to provide programs aimed at raising employee awareness of these interactions.  相似文献

A case of marital therapy is described in which the presenting problem, one of non-consummation, is treated by the standard Masters and Johnson's technique. Using repertory grids at the start and finish of treatment the changing perceptions of both partners and the therapist were determined. In spite of an ostensibly behavioural treatment, substantial changes occurred in the couple's understanding of the nature of their problem. The changes undergone in the couple's perceptions, and their differences from the therapist's assessments of change give rise to speculations about the nature of the therapeutic interaction and suggest further lines of exploration.  相似文献
