Variability in Adaptive Behavior in Autism: Evidence for the Importance of Family History

Adaptive behavior in autism is highly variable and strongly related to prognosis. This study explored family history as a potential source of variability in adaptive behavior in autism. Participants included 77 individuals (mean age = 18) with average or better intellectual ability and autism. Parents completed the Family History Interview about the presence of broader autism phenotype symptoms and major psychiatric disorders in first degree relatives. Adaptive behavior was assessed via the Vineland Adaptive Behavior Scales (VABS). Based on family history variables, age, and intelligence quotient (IQ), 87% of participants were correctly classified as having impaired or average VABS scores. Family history of depression and shyness accounted for the most variance in VABS scores, and they had the greatest influence on VABS Socialization scores in particular. Possible underlying mechanisms include genetics, psychosocial factors, and social resources. This study provides initial evidence of the importance of family history to adaptive behavior in autism and has implications for genetics and treatment.     

Knowledge of the world of work: A test of occupational information for young men

The study evaluates a test of occupational information administered to a national sample of 5000 young men, aged 14–24 in 1966, as part of the National Longitudinal Surveys of employment behavior. The predictive validity of the test score is assessed by reference to multiple regression analyses which confirm the significance of the score as an independent predictor of subsequent hourly earnings and occupational status. Correlation and factor analyses are used to examine the quality of the measurement instrument. All in all, the instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of difficulty. The test's reliability compares favorably with a commercially produced test designed to be used in counseling as a measure of occupational knowledge. With the possible modification of deleting a section relating to knowledge of earnings differentials, the test is commended to those involved in assessing and counseling the occupational choice process.     

Use of first person pronouns as a function of increased objective self-awareness and performance feedback

A recent integrating formalation in social psychology, the Duval-Wicklund theory of “objective self-awareness,” has the core assumption that attention focused on the self is always aversive and, hence, avoided. While faced with either a TV camera or a mirror, and after they had received false feedback concerning their creativity, 98 undergraduates guessed at the meaning of foreign language pronouns, the unobtrusive dependent measure of the direction of the focus of attention. The standard Duval-Wicklund effect was replicated—more attention to self, that is, more first-person pronouns—in the “camera” or “mirror” than in the “no camera” or “no mirror” conditions. However, within the camera or mirror conditions, avoidance of self-focused attention occurred only after negative feedback.     

Occupational mobility as measured by Holland's theory of career selection

This study examined the occupational mobility of men ages 45–59 as measured by Holland's theory of career selection and its relationship to men in the work force. Stability was discussed in two distinct ways: (1) stability within a job, and (2) stability in the kind of work a man does over a career. In his research Holland concluded that Realistic and Investigative personality types would change personality type less often and have more stable job choices in comparison to other personality types. The results of this study supported these findings to some extent, but also concluded that stability in a personality type was strongly influenced by the number of jobs available in a particular personality type and the structure of the labor market demand. In addition the results showed that psychological concepts seem to be more important in changing jobs than in selecting initial jobs.     

Age related changes in the effectiveness of name and visual codes in recognition memory

In the first of three studies college, third grade, and kindergarten Ss were able to determine that two stimuli presented 700 msec apart were the same more quickly if they were visually identical than if they shared the same name. If 3000 msec elapsed between stimulus presentations third grade and college Ss responded at the same rate in making both types of matches, whereas kindergarten Ss appeared to continue to respond more quickly in making visual matches. Study II was an unsuccessful attempt to replicate the kindergarten finding. A warning signal, presented 500 msec prior to the second stimulus, reduced RTs at both interstimulus intervals, but no significant differences in making visual and name matches occurred. In Study III first-graders, responding either with or without a warning signal, were found to respond like the older Ss in Study I. The warning signal again reduced RT at both intervals. The results suggest that Ss across a wide age range are able to use the visual properties of a stimulus for only a very brief period as the basis for making matching judgments.     

Sex and sociability in rats

Three experiments explored the effects of sexual motivation and the opportunity for sexual contact on social attraction in rats. Rats were no more gregarious in cross-sex than in same-sex pairings. Increased male sexual experience and hormonally induced female receptivity both led to increased sexual activity but had no effect on social behavior. Males housed with continuously receptive females showed signs of sexual exhaustion but were as gregarious as males housed alone or with males. It appears that social attraction in rats is not motivated primarily by sexual desires, either direct or sublimated.     

A biographical data analysis of career patterns in engineering

This study focuses on an instrument that appears useful for career guidance or job assignment purposes — the Biographical Data Blank. Responses of three groups of engineers (holding research and development, management, and nonengineering positions) to a life history questionnaire were analyzed. Results indicate that groups could indeed be differentiated using response patterns. In addition, items defining these patterns were related to demands of actual career paths chosen.     

Performance expectancies and affect associated with outcomes as a function of time perspective

An experiment was conducted to investigate the effects of time perspective on performance expectancies and the subjective evaluation of outcomes in regard to a task at which subjects had previously succeeded or failed. Prior research has produced conflicting findings on the subjective evaluation of positive and negative outcomes, but some of the research has dealt with tangible rewards and punishments while other work has been concerned with performance outcomes involving tasks with which subjects were unfamiliar. In the current study subjects first succeeded or failed on either an easy or difficult task. They then stated performance expectancies and made evaluations of the affect associated with success and failure in regard to performing the task again immediately, in 3 wk, or in 21 wk. Results indicated a significant decrease over time for both the satisfaction associated with passing and the dissatisfaction associated with failure. Performance expectancies were significantly higher for the testing period of 21 wk in the future than for either the immediate or 3-wk testing period, but this difference was evidenced only for subjects who initially passed the test.
