This study examined two issues related to the use of nonprofessional counselors (n = 159) within the context of a diversion program for juvenile offenders. First, the relationship of the nonprofessionals' personality traits and general attitudes to client outcome was examined. No statistically significant correlations were observed. Second, the differential impact of various training and supervision factors was examined in terms of nonprofessional satisfaction, attitudes, and locus of control. Results suggested that training intensity, training content, and supervision setting may influence nonprofessionals' attitudes towards various social groups and their satisfaction with the nonprofessional experience.  相似文献

For four of six autistic children who underwent intensive behavioral treatment, the nature of their self-stimulatory behavior changed from initial lowlevel motor behaviors (such as rocking, spinning, twirling) to differing kinds of higher-level behaviors (such as lining of objects, echolalic speech, and preoccupation with spelling and numerical values). The children who changed to the highest levels of self-stimulatory behavior also showed the largest gains in treatment (as determined by IQ scores, school placement, etc.). The changes in self-stimulatory behaviors were attributed to the intense teaching of appropriate social behaviors and the explicit therapeutic suppression of low-level, self-stimulatory behaviors. The long-term therapeutic effects of changing from lower-to higher-level forms of self-stimulatory behavior were discussed.This study was supported by a grant from the National Institute of Mental Health (grant MH 11440). We want to express our thanks to the parents who allowed us to study their children. We gratefully acknowledge the assistance of Maria Audero with the design of the weighted measure, and Tracee Parker with the collection of the data.  相似文献

This note presents the hypothesis than the excessively forceful closure of the mouth of larynx associated with certain types of stuttering may involve a neurological confusion between speech and the human body's Valsalva mechanism, which is designed to increase pulmonary pressure by forceful closure of the upper airway to assist in many types of physical effort. It is suggested that such behavior may result from excessive neuromotor tuning of the Valsalva mechanism prior to speech, especially in situations where the stutterer anticipates the need to “try hard” to speak properly. Such tuning may both interfere with phonation and render the Valsalva mechanism overexcitable to triggering stimuli, such as the increase in subglottal pressure that accompanies the start of articulation.  相似文献

Two left-handed siblings with developmental stuttering are comprehensively described. The methods of study included speech and language evaluation, neurological and neuropsychological examinations, dichotic listening, auditory evoked responses, electroencephalogram, and CT scan asymmetry measurements. The data from each sibling showed evidence of anomalous cerebral dominance on many of the variables investigated. The CT scan measurements showed atypical asymmetries, especially in the occipital regions. These findings support the theory that stuttering may be related to anomalous cerebral dominance, both on functional as well as structural bases. Implications of anomalous dominance and the resultant effect of hemispheric rivalry on speech fluency are discussed.  相似文献

Impulsivity and anxiety are two dimensions of personality which have strong effects upon the efficiency of cognitive performance. The effects of these two variables depend upon characteristics of the task as well as upon four types of tradeoffs between psychological resources. Tasks may be characterized in terms of their relative requirements for sustained information transfer (SIT), short-term memory (STM), and long-term memory (LTM). Resource tradeoffs may be automatic, strategic, directional, or stylistic. Impulsivity effects on performance involve an automatic arousal-induced tradeoff between SIT and STM, strategic tradeoffs of speed for accuracy, and stylistic differences in persistence. Anxiety effects involve strategic, directional, and stylistic tradeoffs.  相似文献

Strengthening local alcohol programs so as to emphasize primary prevention is an active concern among mental health professionals; yet interventions intended to achieve this aim have produced only modest shifts in program orientation in most communities. An analysis of data obtained from those active in local affairs in a small community, using Q-sort techniques, suggested that contrasting perspectives toward alcohol abuse as a social problem may stand as an unseen barrier to relevant change.  相似文献

This article seeks to answer the question whether the term ‘fundamentalism’ is an appropriate label for certain Islamic movements by undertaking a detailed comparison with Protestant Christian fundamentalism, for which the term was originally coined. After an effort to identify and characterize the two phenomena, a number of similarities and differences are discussed. Among the differences is the fact that the most obvious defining characteristics in each case (Biblical inerrancy for Protestants and politicalsocial involvement for Muslims) are of little relevance to the other case. Among the similarities is a common opposition to ‘modernism’ and a tendency to stress what has been distinctive to the Protestant and Islamic traditions, respectively. The conclusion is that, while the two phenomena do have much in common, ‘fundamentalism’ is not an appropriate common label. The author prefers ‘Islamic radicalism’ for the Muslim case and tentatively suggests ‘radical neotraditionalism’ as a common label.  相似文献
