USING HIGH-PROBABILITY INSTRUCTION SEQUENCES WITH FADING TO INCREASE STUDENT COMPLIANCE DURING TRANSITIONS

Making efficient transitions from one instructional activity to another has been shown to increase academic learning time and therefore student achievement. Because compliance with teacher instructions is a prerequisite for efficient transitions, we sought to determine if high-probability (high-p) instruction sequences issued by a classroom teacher would increase student compliance and decrease latency to comply during transitions. Three children in a regular second-grade classroom participated. Each day at the beginning of morning calendar time, the teacher issued five instructions to the class as a group while compliance data were recorded for the 3 target students. Following baseline, a multielement design was used to examine the effects of the high-p instruction sequence. We then systematically faded the number of instructions included in the high-p sequence as a means of transferring stimulus control to low-probability instructions. The procedure was effective for 2 of the 3 participants, and the results were maintained at 2-and 3-week follow-up. The implications of these findings for group applications of the high-p instruction sequence in regular education classrooms are discussed.     

Quantitative evaluation of infant behaviour and mother–infant interaction: An overview of a japanese interdisciplinary programme of research

This paper provides an overview of an interdisciplinary programme of research started more than 20 years ago at the University of Tokyo. A major aim of this programme was (and still is) to develop methods and related forms of quantitative analysis that provide rigorous evaluations of infant behaviour from a particular theoretical perspective. In one part of the programme telethermography is used to measure emotional changes in young infants. Contrary to the accepted view in attachment theory, infants as young as 2–3 months showed evidence of stress following separation from the mother (as indexed by a drop in the skin temperature of the infant's forehead). In another part, we established the presence of interpersonal synchrony between arm movements of the newborn and the speech of the mother and other adults, using computer assisted pattern recognition techniques. On the basis of this finding, we have proposed a simulation model of mother-infant interaction from the perspective of system information theory. In general, our programme of research provides a theoretically driven set of techniques and analytical approaches that may provide deeper insights into early development and parenting.     

Infant and parental pathways to pre-school cognitive competence

In a longitudinal study, 62 parent-child dyads were seen during the second year of life and at 4 years of age. At 12 months, measures included parental sensitive responsiveness during free play, knowledge of cognitive-communicative development in infancy, and level of exploration and disinhibitedness of the infant. At 16 and at 20 months, parental responsiveness and directiveness and infant task mastery behaviour were assessed in constructive play. Quality of verbal guidance of the parent was assessed in a joint attention situation. At 48 months of age, the McCarthy Scales of Children's Abilities were administered at home, together with dyadic tasks. A path analysis revealed a model in which both verbal abilities and perceptual performance outcome measures were well predicted by the quality of parental verbal guidance in the second year. The latter measure was shown to be independent of the socioeconomic status of parents in the group, but was significantly related with knowledge of infant cognitive-communicative development. Of the measures at the outset of the second year, only socioeconomic status remained as having a direct path at pre-school age. The consistency of the model with other empirical findings underscores parental verbal scaffolding as an important shaper of cognitive development.     

Development of child autonomy in eating and toilet training: One- to three-year-old Japanese and French children

This study analyses the interface between children's culture and their development as they learn to perform the daily activities of eating and toileting in culturally appropriate ways. Thirty-three Japanese and 36 French children 12-31 months of age and adults' interventions were observed in public day care centres in Tokyo and in Paris. Within the same time frame, a survey was conducted among the adults (parents and nursery staff) to examine their developmental expectations for children. Observations reveal differences between children's learning in the two countries. Toilet training begins at a later age in Japan and is learned more quickly, whereas learning to eat alone begins earlier than in France but is acquired at a slower pace. The analysis of the surveys shows some discrepancy between adults' conceptions and actual interactions. In both countries, the developmental decrease in physical intervention corresponded with the progress of the child, but adult interventions and strategies varied according to the different cultures. The presence of Japanese adults is greater than those in France, but this does not mean that they intervene physically more often. Finally, instrumental independence begins slightly earlier in Japan.     

Fear,attachment and affiliation: The interaction of functional systems in 8- and 12-month-old infants

In this research fear of strangers has been analysed as it interacts with attachment and affiliation, and in relation to developmental level, in conditions most similar to the natural situations where encounters with unfamiliar persons take place. A total of 30 infants and their mothers participated. The children were divided into two groups (8-9 and 11-12 months). Each infant was approached by two females, who, in turn, produced either of two natural sequences. Our results allowed us to confirm the universality of fear and its coexistence and interaction with attachment and affiliation. As far as the role that developmental level plays, it was noted that in the 12-month-old infants fear reactions were more intense than in the younger ones. Furthermore, the attachment system was more activated in the older group in the intrusive episodes, but when the threatening nature of the situation decreased, attachment was activated less in the 12-month-old group. Another difference was related to control resources. While in the younger infants we observed a tendency to control their own emotional state, the 12-month-old infants tried to gain control over the stranger. These results were interpreted by considering the adaptative value of an increase with age of the capacity to evaluate a situation's threat value, of attachment security, and of behavioural resources permitting some control over the stranger's behaviour.     

AN EXPERIMENTAL ANALYSIS OF “SPILLOVER” EFFECTS ON THE SOCIAL INTERACTION OF BEHAVIORALLY HANDICAPPED PRESCHOOL CHILDRENsp1

The effects of prompting and social reinforcement directed to target subjects on their social behavior and that of peers who never received prompting and reinforcement for positive social behavior, were examined. In a combined reversal and multiple-baseline design, three behaviorally handicapped preschool boys who exhibited divergent social behavior repertoires and varied histories with social reinforcement events, were sequentially exposed to intervention conditions in order to investigate “spillover” of treatment effects. Prompting and reinforcement increased positive social behavior and decreased negative social behavior emitted by all target subjects. The results also demonstrated a “spillover” effect on two target subjects, who at various times were not under intervention, and on the peers as well. The findings suggest that: (a) the direct and indirect effects of intervention procedures may be enhanced by designing treatment based on the social repertoire and reinforcement histories of the subjects; and (b) the treatment “spillover” effect may be increased by applying procedures to two children at once, rather than to one at a time.     

Peer and college-student tutoring as reinforcement in a token economy

Eighteen second-grade children initially received feedback in the form of nonredeemable tokens for reducing their disruptive classroom behavior. Four types of tutoring were then introduced in a Latin Square Design: noncontingent tutoring from fifth-grade peers, contingent peer tutoring, noncontingent college tutoring, and contingent college tutoring. No significant difference was found in the level of disruptive behavior of those children tutored by fifth-grade peers or college students, but contingent tutoring was significantly effective in reducing disruptive classroom behavior.     

Natural rates of teacher approval and disapproval in grade-7 classrooms

The natural rates of teacher verbal approval and disapproval in ten grade-seven classrooms were determined and compared with those described by White (1975). Although there were differences in the observation techniques used and the behavioral, cultural, and ethnic groups sampled, the results were similar. The majority of the teachers displayed individual rates of disapproval that were higher than their individual approval rates. The correlations between levels of on-task behavior and approval and disapproval rates were low. The issues raised by these findings are discussed in terms of directions for further research.
