State conditions and environmental variables were measured over a 5-hour period for 25 students (ages 3-21) with profound and multiple handicaps. Results showed the presence of state sequence patterns, short state change periods, and a relatively small amount of association between specific behavior states and environmental factors and events.…

The second of a three volume report on a University of Kansas approach to developing quantitative measures of motor and perceptual motor functioning in nonhandicapped and severely/multiply handicapped infants and young children presents interobserver reliability results from the measures described in volume 1. Some studies also include a limited…

The first of a three volume report on a project to develop and apply quantitative procedures to measure motor and sensory/motor growth in nonhandicapped and severely/multiply handicapped children presents 17 papers delineating ways to measure motor function. The following motoric functions are considered: visual fixation, visual tracking, visual…

Behavior states and related developmental and medical variables were observed for 34 infants with severe cognitive and multiple disabilities for their first four years. Findings demonstrated emerging state profiles consistent with those found among older populations in previous studies. Results suggest the need for specific, early interventions…

Two studies with 50 students (ages 1 to 21) with severe, profound, and multiply handicapping conditions examined similarities and differences in behavior state conditions. Among findings were that profile groups could be identified by behavior state patterns and that students spent an average of 42 percent of classroom time in state conditions not…

This investigation analyzed information pertaining to behavior states and their relationship to numerous environmental, physiological, and demographic variables and events. The 66 participants ranged in age from 1 to 21 years and were classified as having profound and multiple disabilities, with developmental ages that ranged to 24 months.…

The authors examine existing procedures and instruments used to assess the motor and perceptual/motor skills of severely/multiply handicapped infants and young children. Following an introductory section is a discussion of the rationale for the sequencing of assessment items and the limitations of the instruments for yielding specific quantitative…

Three studies that applied quantitative procedures to measure motor and sensory/motor acquisition among handicapped and nonhandicapped infants and children are presented. In addition, a study concerning the replication of the quantitative procedures for assessing rolling behavior is described in a fourth article. The first study, by C. Janssen,…
