Three models of behavioral effects of genetic disorders characterized by mental retardation were compared: (1) no-specific effect model (all genetic disorders have identical behavioral outcomes); (2) totally specific model (each genetic disorder has unique outcomes); and (3) partially specific model (two or more genetic disorders share outcomes…

A review of research on state behavior among students with profound disabilities is presented, and a model depicting interactions of state with endogenous and exogenous variables is offered. Applications of the model are illustrated through four case studies displaying different state patterns. Measurable attributes of state having implications…

Recent experimental research is synthesized to identify distinctive biobehavioral characteristics of Down's Syndrome persons across their lifespan. It is argued that educational and other intervention programs have not demonstrated strong gains having significant durability or generalization. Recommended is an interactionist function-structure…

This rejoinder to critiques (EC 602 213-215) of the authors' article (EC 602 212) on stereotypy and self-injury in the disabled responds to specific objections raised, including misleading statements, failure to address other existing models, misunderstandings, and need to include neurochemical factors.

This investigation addresses problems of defining verbal imitation, and suggests solutions by analyzing verbal interactions between two children and their mothers. Children were between 18 and 35 months old, with a mean length of utterance between 1.4 and 4.2 morphemes. Analyses focus upon the uses these children made of maternal models; 10…

Although the Tension Reduction Hypothesis (TRH) of alcoholism has been the most popular explanation for alcohol abuse to date, the research addressing this model has provided tenuous support at best. In light of this contradictory support, a coping model of alcohol consumption is proposed. This model is based on the low self-image of…

This paper offers a conceptual framework for the intersection of work and family roles based on the constructs of work involvement and family involvement. The theoretical and empirical literature on the intersection of work and family roles is reviewed from two analytical approaches. From the individual level of analysis, the literature reviewed…

Examines a statistical model in which the users of an online system continually update their estimated probability of success, and quit or continue the search according to the expected utility of each action. The implications for search strategies are discussed. (Author/EM)

A three-level model explains the emergence and maintenance of rhythmic stereotypy and self-injury in disabled individuals: Level 1, internally regulated rhythmic behaviors; Level 2, stereotypy and self-injury as adaptive responses to understimulating or overstimulating environments; and Level 3, stereotypy and self-injury as learned behaviors to…

The psychology of personality has always attempted to define the individual in relation to normative data. However, personality theory should be attempting to define individuals from an interactive measurement model, examining the individual in terms of his own subjective impressions about what he does, with a conception of what he does not do.…

Reviews results of research related to the control system model of how parents and children regulate each other's behavior. Confirmed early formulations that postulated individual differences in children's assertiveness, activity, and person orientation as explanations for differences in parents' child-rearing techniques. (HOD)

Research on trait descriptions of interpersonal behavior tends to converge on a two-dimensional representation in which descriptive variables are arrayed in a circular fashion around the major axes of affiliation and dominance. Wiggins' self-report adjective checklist (1979) reflects this theoretical ordering. To explore the utility of Wiggins'…

Assessment of the prelinguistic behaviors of 43 deaf children (ages 8 to 49 months) of hearing parents in Israel found only partial resemblance to the theoretical model of prelinguistic communication in hearing infants. Unique interrelationships among pointing and early noncommunicative behaviors were found with no correlation between use of…

Models of well being and human functioning have traditionally been based on empirical studies done with children and young adults. As part of an ongoing research program to develop and test a model of effective functioning and positive health in older adults, 31 elderly individuals (7 males, 24 females), with a mean age of 73.58 years, completed…

Suggests typology as initial framework for study of patterns of computer use in the home, along with four sets of independent factors--social status, technical features, sociocultural setting, and personal attributes. This approach integrates patterns of computer utilization with technological, social, and psychological factors to account for…
