The peer relations of preschool children with communication disorders.

The peer-related social interactions of preschool-age children with communication disorders were compared to those of normally developing chronological age-mates. All children were previously unacquainted with one another and participated in a series of short-term play groups. Differences between the 2 groups emerged primarily in terms of overall social activity, as children with communication disorders engaged in fewer positive social interactions and conversed with peers less often during non-play activities. Children with communication disorders also were less successful in their social bids and appeared to be less directive with their peers. However, both groups of children exhibited similar patterns of socially competent interactions including the ability to sustain play (group play), to minimize conflict, to join others in ongoing activities, and to respond appropriately to the social bids of others. Based on peer sociometric ratings, both groups of children were equally accepted. These general patterns of similarities and differences were found in settings in which play groups consisted of all children with communication disorders (specialized settings) as well as in settings in which the play groups included both children with communication disorders and normally developing children (mainstreamed settings). However, even during the relatively brief acquaintanceship process, an analysis of peer preference patterns revealed that children with communication disorders in mainstreamed settings were less socially integrated in the play groups than normally developing children. The potential for additional difficulties in peer interactions for children with communication disorders when children become more familiar with one another and play becomes more intricate was discussed in light of interaction patterns formed during the short-term play groups.

Analysis of Variance↗

Immediate effects of mainstreamed settings on the social interactions and social integration of preschool children.

The immediate effects of mainstreamed and specialized settings on the peer interactions of preschool children with and without developmental delays were examined. Mainstreamed and specialized playgroups were established involving unacquainted peers and using a methodology that ensured appropriate matching of child and family characteristics. For each 2-week playgroup, the social and play interactions of each child were observed during a designated free-play period. Peer sociometric ratings also were obtained. Results indicated higher levels of peer interactions in mainstreamed settings for both typically developing children and children with developmental delays. The immediate impact of mainstreamed settings appeared to be attributed to the social demands and higher interaction levels of the former group. Children with developmental delays were not fully accepted nor totally socially integrated based on sociometric measures and behavioral indices of peer preferences. Implications of these findings for developing intervention programs to maximize children's peer-related social competence was discussed.

Parent perspectives of peer relationships and friendships in integrated and specialized programs.

In-depth interviews of a large community-based sample of mothers of preschool-age children with established disabilities and those classified as at-risk were conducted focusing on issues of children's peer relations and friendships. Results revealed that mothers of children enrolled in both integrated and specialized programs perceived their respective settings as valuable for the development of their child's peer relations and friendships. Mothers of children in integrated settings reported that their child played better and was more social due to the participation of children without special needs. A similar pattern was obtained for mothers of children enrolled in specialized programs in response to a hypothetical situation. Nevertheless, both groups of mothers were clearly concerned about peer rejection and noted the importance of having other children with special needs in the program available as a means of promoting tolerance and acceptance.

Attention deficit disorder with and without hyperactivity: reaction time and speed of cognitive processing.

This study addressed the issue as to whether children reliably diagnosed as attention deficit disordered with hyperactivity (ADD/H) and without hyperactivity (ADD/WO) differed significantly from each other and a clinic control (CC) population on speed and efficiency of cognitive processing. From an outpatient clinic population, 43 ADD/H and 22 ADD/WO children were examined. An analysis of mean reaction time and speeded classification task performance revealed significant group effects on both mean reaction time and on a measure of within-subject variability. ADD/H children performed significantly more slowly and variably than the CC children on several of the speeded classification tasks. However, the ADD/WO group was not distinguished on any measure. Thus, while children may be reliably diagnosed as ADD/H or ADD/WO using behavioral measures, it would appear that they cannot be distinguished on these neurocognitive tasks. Issues related to childhood psychopathology and the neuropsychological basis of ADD/H are discussed.

Lateralization of visual hemifield attention across development.

Heilman and Valenstein (Clinical Neuropsychology, 1979, Oxford University Press, New York) have hypothesized a right hemispheric mechanism which mediates attention bilaterally. Shapiro and Hynd ("The development of functional lateralization in visual hemifield attention." Developmental Neuropsychology, Vol. 1, pp 67-80, 1985) examined the developmental validity of this model and their findings did not provide evidence for a lateralized mechanism for visual hemifield attention in 9, 13, and 18 year olds. However, length of foreperiod and gender effects were noted. This study attempted to compare these groups with a group of normal adults (ages 25-35) using the same reaction time paradigm. The study demonstrated support for the length of foreperiod effect found by Shapiro and Hynd. Hand effects were also found. However, these results do not lend support to either the model proposed by Heilman and Valenstein (1979) or Shapiro and Hynd's (1985) notion of developmental differences across age groups with respect to right hemisphere dominance for mediating attention.

An intervention approach for children with teacher- and parent-identified attentional difficulties.

Using a multimodal and multi-informant method for diagnosis, we selected 33 children by teacher and parent nomination for attention and work completion problems that met DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD). Of the 33 children in this group, 21 participated in the initial intervention, and 12 were placed in an ADHD control group and received the intervention after pre- and posttesting. A similarly selected group of 21 children without difficulties in attention and work completion served as a control group. Each child was assessed on pre- and posttest measures of visual and auditory attention. After an 18-week intervention period that included attention and problem-solving training, all children in the intervention and control groups were retested on visual and auditory tasks. Children in both ADHD groups showed significantly poorer initial performance on the visual attention task. Whereas the ADHD intervention group showed commensurate performance to the nondisabled control group after training, the ADHD control group did not show significant improvement over the same period. Auditory attention was poorer compared to the control group for both ADHD groups initially and improved only for the ADHD intervention group. These findings are discussed as a possible intervention for children with difficulties in strategy selection in a classroom setting.
