Many authors have endorsed the hypothesis that previous emotional experiences may exert a covert influence on behavior, but some findings and replications of the original studies challenged this view. We investigated this topic by carrying out an experiment with the Iowa Gambling Task (IGT), where a dissociation procedure was adopted to…

This study aimed to investigate the relationships between abilities to initiate and respond to joint attention and symptoms of autism that have, and have not, been theoretically linked to joint attention. Participants were 51 boys and five girls with autistic disorder, aged between 2 years and 6 years 5 months. Measures of joint attention…

Two studies were undertaken to determine systematically how preventive behaviors associated with health, accidents, property loss, and financial loss are interrelated. Several dimensions of preventive behavior were found (e.g., checkups, risk taking, dietary patterns), and most of these dimensions were independent. Implications of these findings…

The conjugate lateral eye movement phenomenon was investigated for 52 children aged 2 through 10 using both spatial and verbal-analytic questions. The phenomenon was observed in 50 subjects and appeared well-established by age 3 1/2. Some interesting developmental findings and discrepancies with the results of adult studies are noted.

Examined consistency in behavioral state organization for 30 fetuses and neonates. Assessed heart rate pattern and presence or absence of eye and gross body movements during sleep, finding quiet sleep (QS), active sleep (AS), and indeterminate states in nearly identical proportions. Duration of enclosed QS epochs provided only stable measure of…

The data demonstrate the existence of a unified, negative cognitive content that is associated with depressed mood among normal subjects. Since cognition emerged as a more stable characteristic than affect, one might conjecture that the cognitive component is activated in--and perhaps triggers--the development of depressed mood.

Retrospective accounts of 42 married couples were used to construct a developmental model of courtship. A basic three-stage pattern was found to characterize the majority of relationships from initial acquaintance to marriage: Casual Dating, Serious Dating and Engagement. Changes in the relationships were measured through the use of a standardized…

The play behavior of young children is viewed as a behavioral manifestation of nonverbal thinking. Discussed are issues of relevance to the understanding of the development of thought in general and of the symbolic function in particular. A line of development is proposed which leads from early nonverbal thought as manifested in play, either…

The authors propose that the manager's total career life (total life space, middle level behavior alternatives subject to personal control, and interactive, interpersonal communication, focused on mutual career development) be considered in approaching career development, rather than artificially isolating segments of the individual's life. This…

The study of origin and evolution of man gives new perspective for understanding his behavior. Physical behaviors such as walking and throwing are results of biological evolution which has not kept pace with sociocultural evolution. Irrational decisions by man in social, cultural, and political fields are results of this brain activity. (PS)

Direct observations of animal behaviors can provide clues to understanding human behavior. By such observations of animals close to man, certain behavior patterns have been established. Man's behavior in social and cultural fields is an adaptation of these behavior patterns. (PS)

In a survey of 4-H and non-4-H youths from ten urban and ten rural counties, the author investigated the extent and predictors of drug abuse. (Author)
