INCREASING VERBAL INTERACTION AMONG ELDERLY SOCIALLY ISOLATED MENTALLY RETARDED ADULTS: A GROUP LANGUAGE TRAINING PROCEDURE

The present study examined the effectiveness of a group language training procedure for directly increasing and generalizing the rate of verbal interaction among four elderly, socially isolated, moderately mentally retarded men. A withdrawal of treatment design was used to examine the effect of the procedure that used verbal prompts, behavioral rehearsal, and contingent social praise. Changes in behavior were examined in two generalization settings, one similiar to the training environment (Generalization I) and the other arranged as part of the subjects' daily routine (Generalization II). Baseline data indicated no verbal interaction among the subjects. During treatment the training procedure increased the rate of subjects' verbal interactions not only in the training situation, but also in the two generalization settings. An analysis of the data obtained during the Generalization II situation indicated that subjects' verbal interaction increased not only among themselves, but with nonsubject peers present in this setting. Follow-up data showed that increases in rates of verbal interaction were maintained four months after the cessation of training. The implications of the results for program generalization and work with the language deficient individual is discussed.     

Effects of reinforcement and guidance procedures on instruction-following behavior of severely retarded children

Positive reinforcement, physical guidance, and fading procedures were used to teach two severely retarded children motor responses to a variety of verbal instructions. Subjects' responses to one set of instructions provided the focus for the training procedures. Their responses to a second set of instructions were used to assess the generalized effects of training. The frequency of responses to both sets of instructions was evaluated during Baseline 1, Training 1, Baseline 2, and Training 2 periods. During the training periods, this evaluation was made after the daily training sessions when no training procedures were in effect. Results indicated that the subjects showed pronounced increases in instruction-following behaviors (both trained and untrained) during training periods with decreases in such behavior occurring during the Baseline 2 period. The general findings demonstrate the applicability of the training procedures for producing and maintaining instruction-following behaviors in severely retarded children and for facilitating appropriate responding to instructions not directly involved in training.     

Spontaneous fixation tendencies for visual forms

Haidinger’s brush was used as a method of locating fixation positions on a display. The various experimental patterns studied showed: (1) It is the already organized cortical representation of shape which governs fixation, rather than the peripheral input per se; (2) Acute angles near 20 deg are the most effective angular stimuli: (3) For figures subtending angles less than 5 deg, the eye is directed toward the center of the figure. and not toward its edge; and (4) Removing one segment from a completely enclosed figure may not alter the mean fixation position.     

Effects of voluntary eye movement and convergence on the binocular appreciation of depth

Scaling techniques were employed to establish the relation between perceived distance ratio and physical distance ratio. Measurements were made both with and without free eye movement and under two states of convergence. The results were confirmed using a matching technique. With free eye movement, the perceived ratio is a monotonic increasing function of the physical ratio. Without eye movement, the perceived ratio generally increases, then decreases, as the physical ratio increases. For a given physical ratio, perceived distance ratio is less in the absence of voluntary eye movements. Convergence produces depth micropsia when eye movements are permitted, but not in their absence.     

On-task distractors associated with totball baseball games: a preliminary study

Two totball baseball leagues in southern Louisiana were monitored to judge what type of parental involvement yielded the highest on-task behaviors among participants. 39 children ages 3 to 5 years participated in 3- or 4-inning baseball games with parents on the field. In the Parent on Bases League, a parent stood on first, second, and third base only. In the Parent with Every Child League, a parent stood next to every child on the field. Children were observed on the field at three different dates at 1-min. intervals during the first two innings of one game in both leagues. On-task behaviors were defined as standing in the correct field position and watching the ball. Off-task behaviors consisted of sitting, rolling on the field, talking to a coach or parent, and not watching the ball. A statistically significant difference in the percent of time children spent on-task favored the Parents on Bases League (75.7) versus the other league (50.3). Having fewer parents on the field in these baseball games kept players on-task more effectively than having a parent with each child.     

Evaluation of a statewide initiative to reduce expulsion of young children

This program evaluation study describes 3 years of implementation of Arkansas's BehaviorHelp (BH) system, a statewide expulsion prevention support system for early care and education (ECE). BH coordinates three tiers of supports to ECE professionals, including phone support, on‐site technical assistance (TA), and infant and early childhood mental health consultation (IECMHC). We examine differences in characteristics of those served across BH service tiers, describe short‐term case outcomes, and explore factors associated with expulsions. BH accepted referrals for 1,195 children in 488 ECE programs. The majority of referrals involved male children over the age of three, and most cases were assigned to the TA tier (68.5%). Cases assigned to receive IECMHC (28.4%) were more likely to involve children in foster care, receiving developmental therapies, and with higher rates of exposure to potentially traumatic events. The expulsion rate among referred children was 2.9%, and reported teacher engagement with the support process was high. Teachers receiving IECMHC services reported significant improvements in children's symptoms of emotional and behavioral problems. Exploratory analyses revealed that risk factors for expulsion included being a male, in foster care, in a lower quality ECE environment, and having a teacher with less training in social–emotional development.
