The efficacy of progressive relaxation in systematic desensitization and a proposal for an alternative competitive response--the relaxation response.

The theoretical basis of systematic desensitization is reciprocal inhibition in which an alternative, competitive response to anxiety is conditioned to arousal-producing, phobic stimuli. Abbreviated training in progressive relaxation is believed to serve as a competitive response to anxiety by decreasing autonomic nervous system activity. However, physiologic studies of progressive relaxation have not substantiated that its practice is associated with such decreased autonomic activity. Consequently, the use of progressive relaxation has been a confounding factor in the determination of the function of reciprocal inhibition in systematic desensitization. To confirm and refine the theoretical constructs of reciprocal inhibition, it is necessary to test the effects of a response which is competitive to the anxiety response. Such a response may be the relaxation response which is characterized by physiologic changes consistent with decreased autonomic nervous system activity. Derived from meditational practices, techniques which ehcit the relaxation response incorporate the element of focused attention which has been implicated as a critical factor in systematic desensitization. Thus, the use of the relaxation response should be a more appropriate method than progressive relaxation if the therapeutic usefulness of systematic desensitization is indeed due to reciprocal inhibition.     

Trait anxiety moderation of the effects of life stress on state anxiety

Many theories of anxiety have predicted and much previous research has indicated a person × situation interaction between stressors and trait anxiety. This study examined the hypothesized role of individual differences in trait anxiety in the relationship between naturally occurring stressors and state anxiety scores. Two hundred eighty-seven college undergraduates completed the State-Trait Anxiety Inventory, which provides both state and trait anxiety measures, and the Life Experiences Survey, which provides a measure of the amount of stress a person has undergone in the previous year. Trait anxiety scores were divided into quartiles and correlations between state anxiety scores and Life Experiences Survey scores and multiple regressions for trait anxiety and life stress to predict state anxiety were computed within each quartile. The results were that only in the first quartile was there a significant correlation between life stress and state anxiety, which was contrary to the predictions of state-trait anxiety theory. The validity of state-trait anxiety theory, as it relates to life stress, was questioned.     

A path analysis model of psychosexuality in young women

Path analysis is employed to delineate the relationships among sexual behavior variables, including orgasm consistency, masturbation frequency, cognitive sexual arousal, and satisfaction with sexual responsivity. The analysis provides insights into the processes by which the variables are related to one another and generates specific hypotheses for future questionnaire and experimental research. The results are used to develop a psychosexual model for women, which holds that a masturbation/orgasm sequence may be a prerequisite for an understanding of cognitive elements leading to arousal and their physiological concomitants. Once this platform has been established, a single-partner-oriented sexual adjustment is possible, but a frequent exchange of partners at this time may prove detrimental to sexual satisfaction. Later on in life, intercourse frequency may diminish, and moderate sexual dissatisfaction may develop. The implications of this model for further research are explored. Replication and extension of this study with additional measures and older populations of women is recommended.     

Nature of spelling errors in transcortical sensory aphasia: A case study

The nature and extent of spelling errors in a patient with transcortical sensory aphasia were investigated. The two experimental conditions required the patient to spell monosyllabic and polysyllabic words both verbally and in written form. Analysis of the spelling errors revealed partially preserved knowledge of the visual image of a word as a whole, as well as preserved knowledge of temporal order. Our patient's error patterns in both conditions were more similar than dissimilar. These findings in conjunction with results reported in the literature indicate that patients exhibiting different aphasia syndromes use separate spelling strategies.     

The stutterer's reaction to the telephone as a speaking situation

A review of the literature indicates that one of the most commonly feared talking situations among stutterers is speaking on the telephone. One hundred-thirty stutterers who feared speaking on the telephone were interviewed regarding their fear of telephone calling and answering, the age at which they began to fear calling and answering, and their fear reactions to eight specific telephone calling situations.Data was analyzed for all subjects, male/female, black/white, and mild/moderate/ severe stuttering groups. Analysis indicated that telephone calling was judged to be more feared than telephone answering with the exception of the black stutterers. Acquisition of fear of the telephone occured earlier for telephone answering than for calling within most subgroups. When general reactions to the eight telephone situations were considered, the black stutterers had the most severe fear reactions while the male and moderate stutterers had the least severe reactions.     

Closed- and open-class lexical access in agrammatic and fluent aphasics

Bradley, Garrett, and Zurif (Bradley, Computational distinctions of vocabulary type. Unpublished doctoral dissertation, MIT Press; Cambridge, MA, 1978; Biological studies of mental processes, MIT Press, Cambridge, MA, 1980) have suggested that closed-class word access is normally mediated by a different route than the open-class one, and that the loss of this closed-class route might account for agrammatism. However, in an earlier study ( Gordon & Caramazza, Brain and Language, 15, 143–160, 1982) we were not able to confirm a meaningful difference between closed- and open-class word frequency responsiveness of the type Bradley (unpublished dissertation, 1978) had seemed to find in normal subjects. We have now done a direct comparison of closed-class frequency sensitivity in agrammatic and nonagrammatic aphasics, to directly test Bradley and colleagues' hypotheses and to avoid some of the experimental problems with between-class frequency comparisons. We find that closed-class words behave similarly whether or not the subject is agrammatic. Therefore, the differences between agrammatic and nonagrammatic aphasics must arise at a deeper level (or levels) of lexical processing than the one probed by the frequency sensitivity effect.     

Individual differences in intelligence: A reappraisal of the confluence model

The confluence model posits that an individual's intellectual development is a function of the intellectual environment he or she is exposed to in the home. Families with many children spaced close together are presumed to have intellectual environments inferior to those of families with few children spaced far apart. To date, the major support for the confluence model has come from analyses of the family size-birth order means of large aggregate data sets. Analyses of the individual scores of some of those same aggregate data sets, however, do not substantiate the confluence model. Explained variance for the aggregate (90%+) reduce to less than 3% in the individual analyses. A recommendation is made to shift the focus of the confluence model from family configuration variables to family interaction varibles utilizing longitudinal data from individuals.     

Why Mikey's right and my key's wrong: The significance of stress and word boundaries in a child's output system

The systematic errors children make in the course of phonological development, like adult production errors and adult phonological processes, can provide evidence of language production mechanisms. A detailed investigation of the environments in which velar stops are fronted by a phonologically delayed child reveals that fronting is dependent on both word stress and word boundaries; that it shows lexical exceptions; and that it occurs in output only. This distribution suggests that the child has output lexical representations which are independent of input lexical representations, and that the fronting error occurs in these output representations. It also suggests that prosodic features are crucial to the identification of articulatory features within these representations. Such an analysis has implications for theories of lexical access, and for the development of lexical access in children.
