A preliminary analysis of environmental variables affecting the observed biobehavioural states of individuals with profound handicaps

Recently, various researchers have recommended investigation of biobehavioural states as a worthwhile endeavour toward providing a more valid assessment of students with profound handicaps. To date, the research conducted in this area has largely focused on the biobehavioural state variable in isolation. This pilot study was conducted to examine the relationships between environmental variables and biobehavioural state variables. Six students with profound handicaps were selected as subjects and observed during normal daily school routines. The investigators discovered significant relationships between the students' prior state, position, grouping type of staff cue given, the proximity of the staff and type of activity stimulus provided, and the students' biobehavioural states. A discussion of the results and recommendations for future research are provided.
