Merrill, Edward C.; McCown, Steven M.; Kelley, Shirley – American Journal on Mental Retardation, 2001
Sixteen adolescents with mental retardation and 16 typical adolescents participated in a negative priming procedure in two experiments. Unlike previous studies, this study found that subjects exhibited inhibition under instructions to respond on the basis of stimulus identity in a manner similar to that of individuals without mental retardation.…

Kroeger, Tracy L.; Rojahn, Johannes; Naglieri, Jack A. – American Journal on Mental Retardation, 2001
This study with 50 adults with mental retardation, found that performance on the Facial Discrimination Task (Emotional and Age Tasks) was significantly correlated to the Cognitive Assessment System total score. Hierarchical regression analyses produced results suggesting that cognitive processes are involved in processing facial stimuli in a…

Russell, James – Developmental Psychology, 1984
Two experiments examined the determinants of children's belief or disbelief of statements made to them by other children. In both, the personal characteristics of the child transmitting the message were varied against message type and age of child receiving the message; transmitter characteristics were relative age and social dominance.

Williams, Dean C.; Dube, William V.; Johnston, Mark D.; Saunders, Kathryn J. – American Journal on Mental Retardation, 1998
Two studies compared performance on conditional and trial-unique delayed identity matching-to-sample procedures with five subjects having moderate to severe mental retardation and four subjects with mild mental retardation. Across the studies, six of nine subjects showed lower delayed-matching accuracy when fewer rather than more stimuli were…

Komatsu, Lloyd K.; Galotti, Kathleen M. – Child Development, 1986
Reports on two studies during which 6-, 8-, and 10-year-old children were interviewed about three different types of regularities or rules: social conventions, physical laws, and logical necessities. Shows that older children made more distinctions between social and nonsocial items than did younger children. (HOD)

Maydak, Michael; And Others – Research in Developmental Disabilities, 1995
This study examined the matching and sequencing of quantities, numerals, and arbitrary forms by two individuals with mental retardation. Results showed that sequence training did not readily lead to new matching performances, unlike prior research with college students. Instead, training in matching to sample yielded emergent sequence production…

Strand, Steve C. – Research in Developmental Disabilities, 1991
This study found that teachers' ratings of their 8 severely mentally handicapped pupils' (ages 9-18) classroom behavior were correlated with children's performance on a discrimination learning task. The factors of attention/distractibility and responsivity to consequences correlated significantly with number of errors and number of trials to…

Sims, Wendy L. – Journal of Research in Music Education, 1995
Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…

Cooper, Nancy A. – Journal of Research in Music Education, 1995
Examines the relationship between vocal pitch accuracy and gender, grade level, and the presence or absence of an accompanying unison voice. Reveals no significant differences between unison or individual singing or for gender. Fourth and fifth graders exhibited significant differences. (MJP)
