Background: This study addresses the question to what extent visual impairment leads to additional disability in adults with intellectual disabilities (ID). Method: In a multi-centre cross-sectional study of 269 adults with mild to profound ID, social and behavioural functioning was assessed with observant-based questionnaires, prior to expert…

Three groups of visually impaired children--10 with rubella, 7 with retrolental fibroplasia (RLF), and 9 with blindness other than rubella or RLF--were observed for stereotypic behaviors. Ss were observed in four different environmental settings: classroom/instruction; mealtime activity/breakfast, lunch, or supper; physical education/movement…

A new approach to behavioral control with individuals having both visual impairments and multiple disabilities stresses the use of positive intervention strategies, bases treatment on functional assessments of challenging responses, and emphasizes broad changes in the lifestyles of individuals. Case examples illustrate applications. (Author/DB)

Findings from two studies of 42 children with profound developmental delays (26 males and 15 females) using systematic and intense response-contingent learning opportunities interventions are reported. Response-contingent learning games were used to promote the participants' use of behavior that either produced environmental consequences or…

A functional analysis of eye poking by a four-year-old female with severe developmental disabilities and visual impairments showed that high rates occurred in all conditions. Attempts to identify the maintaining variable found that eye poking decreased only when finger-eye contact was interrupted by blocking the response. (Author/DB)
