The purpose of this study was to examine the behavioral states of individual children for evidence of responsiveness within and without a multisensory environment (MSE). Three children in the age range of 3-10 years with severe multiple disabilities participated in the study. A single-system ABAB design was used. Participants' behavioral states,…

The Facial Action Code (FAC) was derived from an analysis of the anatomical basis of facial movement. The development of the method is explained, contrasting it to other methods of measuring facial behavior. An example of how facial behavior is measured is provided, and ideas about research applications are discussed. (Author)

In this study designed to compare the relative pacifying properties of horizontal and vertical rocking, 13 infants (mean age--58 days) were each tested on two subsequent days. The rocking device was a cradle that could be manipulated to produce side-to-side rocking similar to a commercial cradle or up-and-down rocking. In its up-and-down mode, the…

Direct observation of a child's motor performance by a parent was hypothesized to exert an effect on motor behavior. The presence of a parent observer during practice was hypothesized to exert a depressing effect on learning and a facilitating effect on performance when parent observer was introduced later in practice. Male and female children age…

This study investigates the reactive effects of observers on interactions between teachers (undergraduates and mothers) and toddlers in a preventive educational program. Findings indicate that the presence of an observer differentially affects interactional patterns in the home. More specifically, undergraduates and toddlers are relatively…

FOR 5 WEEKS, 2 OBSERVERS MADE DAILY VISITS TO A LABORATORY PRESCHOOL TO COLLECT INFORMATION ON THE AMOUNT AND KINDS OF POSITIVE SOCIAL REINFORCEMENT CHILDREN GIVE TO EACH OTHER IN NURSERY SCHOOL. SEVENTY CHILDREN (AGED 3 YEARS 4 MONTHS TO 4 YEARS 9 MONTHS) WERE GROUPED INTO 2 OLDER AND 2 YOUNGER CLASSES. EACH CHILD WAS OBSERVED IN RANDOM ORDER FOR…

In this study an attempt was made to measure variables which were expected to be related to individual differences in infants' social responsiveness toward strangers. The subjects were 48 infants (24 boys and 24 girls) between 8 and 13 months of age. Most were children of Cornell University faculty or graduate students, but a broad range of…

The purpose of the observational system presented here is to record the behavioral interactions between infant and mother, focusing on the sequential and contextual features of the social communication patterns accessible through direct home observation of mothers and their 3- to 4-month-old infants. The present system of continuous data recording…
