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.     

Dichotic speech perception: A comparison between stuttering and nonstuttering children

A stop consonant-vowel dichotic listening task was administered to 90 right- handed boys, 30 in each age group of 5, 7, and 9 yr. Half in each group were stutterers, half nonstutterers. Two and a half times as many stutterers as nonstutterers were found to display either a left-ear advantage (LEA) or no ear advantage (NEA). This finding suggested a greater tendency on the part of stutterers, as opposed to nonstutterers, for reversed or bilateral representation of the auditory speech areas of the brain. In addition, both stutterers and nonstutterers displayed significant developmental increases in the number of times they were able to identify both dichotic speech stimuli, thereby supporting the hypothesis of an age-related increase in children's total information processing capacity. The results are discussed in terms of the differences between stutterers and nonstutterers with respect to the issues of motor representation, cognitive modes, and higher-order linguistic processes.     

Learning from negative outcomes in stuttering therapy: I. Getting off on the wrong foot

Considering the long history of research into stuttering, it is surprising that so little time has been devoted to the study of factors that contribute to the success of therapy. Even less attention has been devoted to uncovering forces that promote poor treatment outcomes. In this article and the companion piece that follows it, an attempt has been made to delineate what may prove to be predictors of unsuccessful therapy. In this first of the two articles, the focus in on the identification of patient, extraclinical, and clinician variables that could act to negate progress during the establishment phase of treatment.     

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.     

Early discrimination among small object collections

Two studies are presented which examine the young child's ability to discriminate between two small object collections on the basis of numerosity and to maintain that discrimination across changes in number-related cues. A transfer procedure and counting tasks were also included. In Study 1, 2-, 3-, and 4-year-olds were reinforced for choosing either a two- or three-item array when length-density cues were manipulated across two training phases of 20 trials each. Training was followed by a transfer task in which one- and four-item arrays were displayed. Most 2-year-olds were able to learn the discrimination while at the same time displaying little quantitative ability. Further, their transfer responses were transpositional in nature. In Study 2, 2-year-olds were given a similar discrimination task in which numerosity was contrasted simultaneously with length-density and area-brightness cues. Again, most children learned the discrimination and transferred that learning on the basis of relational cues.     

Effects of naloxone on acquisition and extinction of jump-up avoidance behavior in rats

Two experiments were carried out to assess the effects of the opioid antagonist, naloxone, on the acquisition and extinction of shock avoidance by rats in the jump-up apparatus. In Experiment 1 naloxone pretreatment facilitated acquisition but had no effect on extinction of avoidance behavior. In the second experiment the effect of naloxone on acquisition was replicated and in addition, it was shown that naloxone enhanced freezing when a response prevention or flooding procedure was introduced. Again naloxone failed to alter the course of extinction, nor did it interact with the effects of flooding which, by itself, facilitated extinction. The results suggest that naloxone's effects are limited to increasing the functional intensity of the US, and provide further support for the dissociation between extinction of avoidance behavior and other indices of fear.     

Holland's theory and non-college-degreed working men and women

The main concern of this study was to investigate differences between men and women employed in traditional male occupations using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 103 male and female non-college-degreed workers in three occupations (bus-taxi drivers, police officers, and car sales agents) corresponding to three of Holland's environmental categories (Realistic, Social, and Enterprising). In general, the results indicate that the VPI and SDS scales to some extent discriminate among occupational groups, but expected patterns do not always occur within and between occupational groups.
