Relative aversiveness of subcutaneous shock and footshock was assessed by means of a spatial preference technique. Subcutaneous shock was less aversive than footshock by a factor of 10, except at near lethal shock intensities. where receptor-cell hyperpola rization. electrocauterization, and/or muscular tetanization may have occurred 相似文献

A vacuum-tube constant-current shock source. providing ac, smooth dc, and pulsating dc output is described. In addition to output flexibility. the shock source is compact, inexpensive to construct. and has undergone 4 years of testing and laboratory use. Operating instructions, theory of operation, and suggested modifications are included along with performance specifications. 相似文献

Deafness, spelling and rhyme: How spelling supports written word and picture rhyming skills in deaf subjects 总被引:1,自引:0,他引:1
Ruth Campbell Helen Wright 《The Quarterly Journal of Experimental Psychology Section A: Human Experimental Psychology》1988,40(4):771-788
Orally trained, congenitally deaf adolescents and hearing, reading-age-matched control subjects made rhyme judgements for pictures and for written words. Hearing children performed the task accurately. By contrast, the deaf group were very poor at rhyme judgement for words and for pictures. For hearing children, word rhyme judgement was more accurate when the words were congruent in their spelling pattern (e.g. bat/hat), less accurate when the spelling pattern of the rhyming words was incongruent (hair/bear). Deaf subjects showed an even more pronounced effect of spelling congruence; their ability to match for rhyme when written words did not share the same spelling pattern was extremely poor. Moreover, spelling congruence predicted deaf subjects' picture rhyming skills.
We conclude that oral training for deaf people does not always permit them to achieve a reliable phonological representation of speech from lip-reading and residual hearing alone. Instead they use the written spelling of the word. This result is not predicted from some previous results that suggest that orally trained deaf people can make direct, spontaneous use of rhyme in the processing of visually presented material. 相似文献

Agency, communion, and gender were compared as predictors of communication style in the conversations of 76 unacquainted pairs of male-female college students. Each dyad was given a popular issue to discuss for 5 min. Agency and communion were measured using Spence and Helmreich's (Masculinity and Femininity: Their Psychological Dimensions, Correlates, and Antecedents, Austin, Texas: University of Texas Press, 1978) Personal Attributes Questionnaire. Self-perceived agency was significantly associated with verbal assertiveness: High-agency persons used fewer indirect statements and fewer passive self-references than low-agency persons. Nonsignificant trends indicated that self-perceived communication tended to be associated with interpersonal involvement: High-communion persons used fewer impersonal references and were liked more than low-communion persons.An earlier version of this paper was presented in the Symposium on Interdisciplinary Approaches to Language and Gender at the 91st annual convention of the American Psychological Association, Anaheim, California, August 1983.Several people contributed to this study in various ways. Conversations with various friends and colleagues were important inspirations for the research. In particular, I would like to thank Robert de Mayo. Gina Ralke, Jorge Reyes, James Bucci, and Mark Michaels were outstanding members of a research team that led to the design and eventual implementation of this study. Ronald Gelb, Donna Brennan, and Lynda Kern also assisted. Nancy Henley is especially appreciated for her support and advice. William McCarthy and an anonymous reviewer made helpful comments on earlier drafts of this paper. 相似文献

Recent experimental investigations on patients with unilateral brain lesions and on neurologically intact people are reviewed with a view to appreciating the role of lateralised processes in emotion. Distinctions are drawn between the perception of emotion, the expression of emotion and the interaction of these two factors in studies of latéralisation. In spite of a mass of contradictory findings, and despite the interaction of structural and cognitive factors in some studies of emotion, there are some fairly robust findings. The right hemisphere seems to be specially involved in tasks requiring emotional analysis, particularly when the tone of the displayed emotion is negative. The right hemisphere, too, appears to be particularly involved in displaying some negative emotions. Among the important problems which await resolution, we do not know whether emotional events are apprehended independently of cognitive ones, nor how mood affects the “Cerebral balance of power”. 相似文献

This study investigated the generalization of spontaneous complex language behavior across a nontraining setting and the durability of generalization as a result of programming and “loose training” strategy. A within-subject, across-behaviors multiple-baseline design was used to examine the performance of two moderately retarded students in the use of is/are across three syntactic structures (i.e., “wh” questions, “yes/no” reversal questions, and statements). The language training procedure used in this study represented a functional example of programming “loose training.” The procedure involved conducting concurrent language training within the context of an academic training task, and establishing a functional reduction in stimulus control by permitting the student to initiate a language response based on a wide array of naturally occurring stimulus events. Concurrent probes were conducted in the free play setting to assess the immediate generalization and the durability of the language behaviors. The results demonstrated that “loose training” was effective in establishing a specific set of language responses with the participants of this investigation. Further, both students demonstrated spontaneous use of the language behavior in the free play generalization setting and a trend was clearly evident for generalization to continue across time. Thus, the methods used appear to be successful for training the use of is/are in three syntactic structures. 相似文献

Sixty-eight 2-and 3-year-olds (46 parent-referred, 22 controls) participating in an identification, assessment, and follow-up study of hyperactivity and related behavior problems were evaluated on parent-report, observational, and cognitive measures. Referred youngsters were described by both parents as more active, inattentive, difficult to discipline, and aggressive with peers than were controls. Mothers of referred children also reported a more difficult infancy period. Laboratory assessments confirmed parental reports of current problems. Referred children shifted activities more during free play, were more active and inattentive during structured tasks, and made more impulsive responses on a delay task than did controls. Discriminant function analysis indicated that parental ratings of activity paired with laboratory measures of sustained attention and impulsivity correctly classified 88% of the sample. These data suggest that the core symptoms of hyperactivity can be identified in very young children, although their prognostic significance remains to be determined.This research was supported by Grant No. R01 MH 32735 from the National Institute of Mental Health to the first author. Thanks are due to the parents and children who participated so enthusiastically in this study. The dedication of Patricia Cluss is gratefully acknowledged.

Predictions derived from Eysenck's theory of personality were tested in two samples by relating extraversion scores to library study locations, frequency of study breaks, and self-report of factors which influence study location. The predicted main effects for study location were found, with extraverts occupying locations that provided greater external stimulation. Positive correlations were consistently found between extraversion and preferred level of noise, preferred level of socializing opportunities, and rated importance of socializing opportunities. The prediction that extraverts would take more frequent study breaks was supported in Sample 1 but not replicated in Sample 2. The data are interpreted as providing direct support for Eysenck's theory of behavioral differences and mixed indirect support for his theory of neurological differences between introverts and extraverts. 相似文献
