The early development of self-injurious behavior (SIB) in 16 young children with developmental disabilities was tracked over an 18-month period. Naturalistic observations in each child's classroom found a significant association between early SIB and low levels of social contact, which may be considered as a risk marker for SIB exacerbation.…

This paper reports the results of a Monte Carlo investigation of Type I errors in the single group repeated measures design where multiple measures are collected from each observational unit at each measurement occasion. The Type I error of three multivariate tests were examined. These were the doubly multivariate F test, the multivariate mixed…

This study of two fifth grade classes investigated students' reports of attention, understanding, cognitive processes and affect during a nine-day mathematics unit on measurement. These self-reports appeared more valid indicators of classroom learning than observed time on task. Student affect mediated the relationship between instructional…
