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.  相似文献

The voice reaction time (VRT) of 5-yr old, 9-yr old, and adult stutterers and nonstutterers was investigated. Subjects initiated the sound / Λ / in response to fifty-five 1000-Hz tones of 1 sec duration. The tones were presented in five equal sets of 11 tones each with the silent intervals between the tones randomly selected to be 3, 4, 5, or 6 sec. Data analysis was based on responses 2–11 for each set. The VRTs for both the stutterers and the nonstutterers decreased significantly as an inverse function of age, with the largest decrease in reaction time occuring between 5 and 9 yr. The VRTs for the stutterers, however, were significantly slower than those of the nonstutterers at each of the three age levels. The results suggest that observed disruption in the laryngeal behavior for at least some stutterers may not result from the development of stuttering with age, but may contribute to early difficulty in the child's ability to produce fluent speech. Consideration of central factors are discussed.  相似文献

A reanalysis of the intercorrelations of Wechsler subtests, achievements tests, and Piagetian tasks originally published by Stephens et al. (1972) has corrected errors in the original design and has used models which allow both differences and similarities to appear. Unit weighted composites of the two sets of tests were formed after first partialling chronological age out of the complete table of intercorrelations. The correlation between the composites is .876 which corrects, using split-half estimates of reliabilities, to .918. Next the matrix of partial correlations was factored and the factors rotated to a hierarchical structure. Piagetian tasks contribute almost equally to the definition of the general factor in intelligence along with the Wechsler subtests and the achievement tests. The general factor, furthermore, makes the single largest contribution to the variance of most of the measures of both sets. The smaller group factors consist of an Academic Achievement factor and three Piagetian factors. Of the latter the largest and most clearly identified is the factor called Operational Thought in the earlier analysis, but is here described simply as Conservation. It is concluded that the evidence for communality in function far outweighs the differences between intelligence tests and Piagetian tasks.  相似文献

This study, using the Vocational Preference Inventory (VPI) and the Self Directed Search (SDS), explored the concurrent validity of Holland's theory for employed college-degreed black women. The VPI and SDS were administered to 93 black women workers in occupational environments consistent with Holland's six vocational environments. The results revealed that four scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed college-degreed black women.  相似文献

Kindergarten, first-grade, and second-grade children (5, 6, and 7 years of age, respectively) performed a Luria-type verbal control task in which motor responses are initiated to positive stimuli and inhibited to negative stimuli. The task was performed by motor responding only and verbal self-directed motor responding, with these conditions reversed in sequence for one half of each grade group. Although motor responding and verbal-motor responding by the two younger groups were generally poor, their performance equalled that of the second graders when the verbalizing condition followed the silent, motor-only condition. For these children, verbalizing appeared to constitute a second task which interfered with motor responding. Prior practice on motor-only responding, however, facilitated subsequent, concurrent performance of the two tasks. No interference or practice effects were found for the second graders. The results suggested that self-instructional training programs are likely to be successful when adequate verbal-motor coordination can be assumed or when the motor response is within the child's repertoire.  相似文献

College students were given the opportunity to falsify self-reported scores on a task to gain course credit. Personality and perceived parent behavior data were obtained in a counterbalanced design. Male cheaters were significantly higher in Aggression, Exhibition, Social Recognition, and Harmavoidance but lower in Autonomy (PRF scales) and ACT scores. Female transgressors were reliably lower in harmavoidance and higher in Impulsivity than noncheaters. Among males, no parent scales differentiated transgressors and resisters. Among females, parent scales reflecting reports of lower father warmth and fewer maternal equalitarian interactions but higher Hostile Control significantly differentiated cheaters from noncheaters. These findings were discussed, particularly in terms of the sex differences which suggest that males and females may cheat for different reasons.  相似文献

Selected studies in recent research literature are examined with regard to (a) their methodological adequacy in establishing dimensions of individual differences in information-processing abilities, and (b) the theoretical problems involved in inferring psychological processes from individual difference dimensions. Many methodological inadequacies are noted, including use of small Ns, questionable procedures in establishing variables (e.g., use of raw difference scores), improper or inadequate use of factor analysis and other multivariate statistical techniques, and poor presentation of results. On the whole, little progress has been made thus far in identifying psychological processes through research in individual differences, even though this research approach is viable and potentially useful. Serious theoretical difficulties arise in attempting to infer the nature and operation of psychological processes merely from the identification of individual difference trait dimensions. Promising research, however, is represented by studies in which an effort is made to analyze tasks into their components, to vary task characteristics, and/or to consider the strategies that individuals can employ in performing the tasks.  相似文献

Impairment of auditory perception and language comprehension in dysphasia   总被引:3,自引:0,他引:3  
Men with chronic focal brain wounds were examined for their ability to discriminate complex tones, synthesized steady-state vowels, and synthesized consonant—vowel syllables. Subjects with left hemisphere damage, but not right hemisphere damage, were impaired in their ability to respond correctly to rapidly changing acoustic stimuli, regardless of whether stimuli were verbal or nonverbal. The degree of impairment in auditory processing correlated highly with the degree of language comprehension impairment. The pattern of impairment of the group with left hemisphere damage on these perceptual tests was similar to that found in children with developmental language disorders.  相似文献

Previous data have shown that stereotaxic center median lesions alone or lesions in the amygdala, unilateral left and right and bilateral, do not impair verbal paired-word associates learning. However, “interactional” combined lesions in the amygdala and center median nucleus on the left side result in a significant decrease in test scores. Analysis of the types of errors made postoperatively by the six patients with this lesion combination indicates the persistence over trials of misnaming errors vs errors of omission. These findings are compatible with hypotheses of an alerting function performed by medial thalamic structures which, for effective learning, cosponsor attention to stimulus cues. Defective alerting is held to result in faulty labeling and subsequent mismatching (see Ojemann, 1975, Brain and Language, 2, 101–120, and Fedio &; Van Buren, 1975, Brain and Language, 2, 78–100).  相似文献

Two hypotheses were evaluated. One proposed that the more prominent a body landmark the less anxiety will be evoked by a theme linked to that landmark. The relation was determined between landmark prominence and anxiety evoked by a taped message appropriate to the landmark-linked theme. Two female samples were studied. The findings supported the hypothesis. A second hypothesis proposed that enhancing awareness of body landmarks under threat conditions is positively related to degree of masculinity and negatively related to degree of femininity. Changes in landmark awareness during appropriate taped messages were studied in two male and two female samples. Masculinity-femininity was also measured. The findings were particularly supportive of the hypothesis relating masculinity to mobilization of landmarks.  相似文献
