The question-answer exchange between mothers and young children

Investigated associations between the questioning and answering behaviour of mothers and children in a design that allowed analyses within as well as between social classes. Thirty-two six-year-old children volunteered their knowledge and asked questions of their mothers about a variety of objects in a natural context. Social class differences in the children were found in the quality of questioning and the amount of knowledge displayed, but for the latter there were differences between tasks, and the incidence of questioning confounded the predictions made. Class differences in mothers' behaviour likewise differed by task. An index of the mothers' provision of cognitive meaning and of feedback was shown to correlate highly with children's rates of questioning and knowledge revealed both within and across classes.     

Redundancy analysis an alternative for canonical correlation analysis

A component method is presented maximizing Stewart and Love's redundancy index. Relationships with multiple correlation and principal component analysis are pointed out and a rotational procedure for obtaining bi-orthogonal variates is given. An elaborate example comparing canonical correlation analysis and redundancy analysis on artificial data is presented.A Fortran IV program for the method of redundancy analysis described in this paper can be obtained from the author upon request.     

An evaluation of reality orientation therapy

An evaluation was made of reality orientation therapy utilizing 14 male patients with dementias of various types. The therapy is designed to improve memory and reduce confusion in elderly and demented individuals. Utilizing a group comparison with crossover design, it was found that the patients improved significantly over sessions on orientation items actually taught during those sessions. However, no significant improvement was found on a series of generalization items consisting of orientation-related questions that were not asked during sessions. Furthermore, there was no generalization to ward activities. It was noted that individual responses to the treatment were quite varied, and so three cases reflecting highly different responses are presented.Indebtedness is expressed to the Veterans Administration for support of this research.     

Adaptive behavior in young children of emotionally disturbed women

Children of mentally-ill parents are population at increased risk for psychiatric disorder, and recent research has focused on the psychological development of these individuals. The Rochester Adaptive Behavior Inventory (RABI) was developed to measure the adaptive behavior of such high-risk children based upon a parental interview. Scales defining specific behavior spheres were reproduced in four samples of 30- and 48-month-olds. These scales differentiated high-risk children along dimensions of maternal psychopathology and social status. Global measures of maternal illness, such as severity of symptoms, proved to be more powerful than specific diagnosis. Race and socio-economic status also had a major impact on adaptive behavior. Implications of the data for high-risk theories of schizophrenia are discussed.     

SENSORY EXTINCTION AND SENSORY REINFORCEMENT PRINCIPLES FOR PROGRAMMING MULTIPLE ADAPTIVE BEHAVIOR CHANGE

The role of sensory reinforcement was examined in programming multiple treatment gains in self-stimulation and spontaneous play for developmentally disabled children. Two phases were planned. First, we attempted to identify reinforcers maintaining self-stimulation. Sensory Extinction procedures were implemented in which auditory, proprioceptive, or visual sensory consequences of self-stimulatory behavior were systematically removed and reintroduced in a reversal design. When self-stimulation was decreased or eliminated as a result of removing one of these sensory consequences, the functional sensory consequence was designated as a child's preferred sensory reinforcer. In Phase 2, we assessed whether children would play selectively with toys producing the preferred kind of sensory stimulation. The results showed the following. (1) Self-stimulatory behavior was found to be maintained by sensory reinforcement. When the sensory reinforcer was removed, self-stimulation extinguished. (2) The sensory reinforcers identified for self-stimulatory behavior also served as reinforcers for new, appropriate toy play. (3) The multiple treatment gains observed appeared to be relatively durable in the absence of external reinforcers for play or restraints on self-stimulation. These results illustrate one instance in which multiple behavior change may be programmed in a predictable, lawful fashion by using “natural communities of sensory reinforcement.”     

Judgments of similarity and spatial models

Ss judged the similarity between all pairs of stimulus objects under 3 conditions: when the objects were (a) Munsell 5R color patches varying in value and chroma; (b) parallelorams varying in size and tilt; and (c) circles-with-radius varying in diameter and angle of radius. For each set of judgments, the pattern of deviations from the Euclidean model was used to diagnose the most appropriate spatial model. The results confirm previous findings that the Euclidean space is appropriate for judgments of color patches, but that the city block space is appropriate for judgments of geometrie forms which vary on perceptually distinct dimensions.     

Human, free-operant avoidance of “time out” from monetary reinforcement

To assess the aversive effects of withdrawing monetary reinforcement, human subjects were exposed to a free-operant avoidance procedure in which periods of no reinforcement occurred if the subject failed to respond, and each response postponed withdrawal of reinforcement. Avoidance behavior was developed either through specific instructions about the consequence of responding or through preliminary escape-avoidance training. In all cases, rates of response were found to be a positively accelerated function of decreases in the duration by which responding postponed reinforcement withdrawal. The findings with respect to the function relating avoidance behavior to the interval of postponement were viewed as similar to those obtained when shock is used as the aversive event in free-operant avoidance conditioning.     

Gender Differences in the Relationship of Language Development to Disruptive Behavior and Peer Relationships in Preschoolers

The present study examined whether there are gender differences among preschoolers in how language development is related to disruptive behavior and peer relationships. Participants were 185 largely minority, preschool children from low income families and their 16 teachers. Videotaped observations were coded to assess disruptive and off-task behavior in group learning situations. Teachers rated disruptive behavior and the quality of peer relationships and they provided information about service referrals. Language skills were assessed with standardized tests. Lower levels of language skills were more strongly associated with disruptive behavior and poor peer relationships for boys than for girls. Disruptive behavior was related to the probability that a child would be referred for services. Language development difficulties tended to be seen by teachers only when paired with behavior problems.
