Cumulative integrated electromyographic (EMG) activity was recorded from laryngeal and masseter sites from ten stutterers during a five trial oral adaptation sequence. Results showed more activity at the laryngeal site than the masseter site. While significant reductions in EMG activity were not found, patterns were shown to be related to the subjects' dysfluency patterns over trials. Results were interpreted as suggesting that reduced muscle activity and adaptation (when they occur) are artifacts of other behavioral modifications resulting from overt motor practice. 相似文献

This study assessed the effect of a voice-activated masking unit, known as the Edinburgh Masker, on the speech of four stutterers during oral reading and spontaneous speech. The results show that one stutterer reduced stuttering almost completely whenever the masker was activated. Two subjects showed either marginal or temporary reductions of stuttering during one speaking condition but showed no change in the other condition. The other subject reduced stuttering only during spontaneous speech. No reduction in stuttering was associated with reduced speech rate. A perceptual analysis procedure conducted to assess for altered speech quality during masking conditions found changes in speech quality were evident in two subjects. The clinical implications of these findings are discussed. 相似文献

Recent and ongoing research into the speech production abilities of stutterers has followed four disparate paths. First, there have been objective studies of physiologic, aerodynamic, and acoustic parameters of stutterers' habitual speech patterns and the patterns they display while speaking in the presence of such novel stimuli as DAF or masking. Second, investigators have undertaken the fiberoptic examination of stutterers' larynges during fluent and stuttered utterances. Third, there have been studies of the speed with which stutterers start and terminate voicing independent of the act of speaking. Finally, there have been investigations of possible perceptible differences between the fluency of stutterers and normal speakers. Each of these four types of research is examined. Tentative conclusions are drawn, and directions for future theorizing and experimentation are suggested. 相似文献

This paper is the third in a series beginning with a report (by the authors) of research on the application of Holland's theory of careers to women and men. Holland's response, “The Virtues of the SDS …” is considered, in particular, research he cites on the effect of the Self-Directed Search (SDS) on counselees and his advocacy of raw score reports of personality patterns. The widely divergent career options suggested to men and women by SDS raw scores are noted and misunderstandings concerning the implications of Holland's assessment procedures for his theory are discussed. Holland's defense of raw score reports of personality characteristics is found wanting, especially in light of the support provided for his theory by normed scores. 相似文献

The purpose of this study was to examine the relative effectiveness of sex-balanced and sex-restrictive raw score interest scales in discriminating among vocational preference groups. Analyses were conducted separately for 502 males in six vocational preference groups and 878 females in five vocational preference groups. The degree and nature of the discrimination among groups were highly similar for the two types of scales for both males and females. Centour scores derived from sex-balanced and sex-restrictive raw scores resulted in essentially the same percentages of correct classifications of group membership. The results of this study suggest that the large sex differences traditionally found in interest inventory items may not be a necessary concomitant of validity. Hence, interest inventory reports that reflect these differences may unnecessarily restrict the career suggestions they provide to women and men. 相似文献

Two experiments were reported investigating the possibility that normal children (6- to 7-years old) and retarded children (9- to 10-years old) equated for immediate memory performance may not use effective strategies to eliminate interference from irrelevant information in memory. In both experiments a directed forgetting paradigm was used in which the children were presented with two sets of four pictures, and recalled only one set on each trial. On some trials, there was a cue to forget the first four and to remember only the last four pictures. In the first experiment both groups adopted a passive-active strategy in which the to-be-remembered items were processed actively only after a forget cue. Experiment 2 replicated this pattern of results. The use of sophisticated directed forgetting strategies seemed to be beyond the immediate abilities of these children. Two possible interpretations of the passive-active strategy were offered: (a) The strategy was an attempt to cope with the presence of occasionally irrelevant information and (b) The strategy was an attempt to cope with memory overload. 相似文献

Language recovery in aphasic patients who received one of three types of speech and language treatment was compared with that in aphasic patients who received no treatment. One hundred aphasic patients were followed from 2 to 4 weeks postonset for 1 year or until recovery, using a standardized test battery administered at systematic intervals. Both treatment methods provided by trained speech-language pathologists were efficacious, while the method provided by trained nonprofessionals approached statistical significance. Small group size prevented resolution of the question of whether one type of treatment was superior to another. 相似文献

This article reviews research concerning the use of operant conditioning in stuttering therapy, and discusses the clinical implications of this literature. In order to be considered for this review, a report had to treat the findings of research specifically designed to use operant conditioning in the manipulation of speech disfluency. This body of experimental literature clearly indicates that operant management techniques can effectively reduce stuttering with punishment of disfluencies producing more notable results than reinforcement of fluent responses. Operant conditioning is an effective means of modifying stuttering behavior and should be more visible in terms of procedures used by speech therapists. 相似文献

The development and psychometric characteristics of the Medical Career Development Inventory (MCDI) are described. The MCDI represents the initial construction of a career maturity measure for a homogeneous population of adults who encounter a common set of vocational development tasks. The inventory is intended to measure both degree of vocational development and readiness to cope with the developmental tasks encountered in a physician's career. The MCDI includes 35 items that address coping behaviors germane to dealing with the vocational tasks constituting the career development continuum of physicians. Initial evaluation of the MCDI's psychometric properties with a sample of 160 student-physicians supported the content validity of the items, construct validity of the scales, and criterion validity of the inventory. 相似文献
