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.

The family's functioning with newly diagnosed breast cancer in the mother: the development of an explanatory model.

Despite the high rates of breast cancer in the child-rearing mother, there is extremely limited research on the effects of the illness on the children, marriage, and parent-child relationship. The current study tested an explanatory model of family functioning with breast cancer based on data obtained from standardized questionnaires from 80 diagnosed mothers and partners with young school-age children. Path analysis results for data obtained from both the mothers and the partners revealed a similar pattern. More frequently experienced illness demands were associated with higher levels of parental depressed mood which negatively affected the marriage. When the marriage was less well adjusted, it negatively affected the family's coping behavior. Household functioning was positively affected by heightened coping activity and by higher levels of marital adjustment. Children functioned better when the non-ill parent more frequently interacted with them and their families coped more frequently with their problems.

The impact of parental life change on the early development of children.

The effect of parental life change on children's mental and social development was explored in a longitudinal study of 193 families. Data on life changes, social supports, home environment, child development and interactions were obtained in a series of nine interviews from before the child's birth to 48 months after birth. For the sample as a whole, significant negative correlations were obtained between maternal life change in the first year of the child's life, and the child's IQ and receptive language at 4 years. An examination of subgroups revealed, however, that this relationship was strongest for mothers low in both personal coping resources and in social support. Findings suggest that both direct and indirect effects of maternal life change on the child contribute to the observed relationship.

Prediction of IQ and language skill from perinatal status, child performance, family characteristics, and mother-infant interaction.

193 basically healthy working-class and middle-class mothers and their infants participated in a 4-year longitudinal study which focused on the relative potency of several clusters of variables for predictions of intellectual and language outcome during the preschool years. The major results were: (1) Measures of perinatal or infant physical status were extremely weak predictors of 4-year IQ or language. (2) Assessments of child performance were poor predictors prior to 24 months, but excellent predictors from 24 months on. (3) Assessments of mother-infant interaction and general environmental quality were among the best predictors at each age tested, and were as good as measures of child performance at 24 and 36 months in predicting IQ and language. (4) Measures of the family ecology (level of stress, social support, maternal education) and parent perception of the child, especially when assessed at birth, were strongly related to child IQ and language within a low-education subsample, but not among mothers with more than high school education. Patterns of prediction were similar for 48-month IQ and 36-month receptive language; predictions were notably weaker for 36-month expressive language.

Influence of enucleation upon two-way avoidance behavior of rats, hamsters, chinchillas and BALB/cJ mice.

Several rodent species were blinded and their two-way avoidance behavior was compared to unoperated controls. Blindness facilitated avoidance learning in BALB/cJ mice, impaired learning in hamsters and had no significant effect on albino rats, hooded rats and chinchillas. Effects of blindness upon intertrial locomotor activity correlated well with effects of blindness upon avoidance learning. Preventing intertrial activity abolished the effect of blindness in mice, and did not change performance of blind albino rats.

Psychosocial adjustment of the family to breast cancer: a longitudinal analysis.

The purpose of the current study was to assess the impact of the mother's breast cancer on her family during rehabilitation and to determine the processes families use to adjust to the illness over time. Data were obtained from 111 child-rearing mothers with breast cancer on three occasions at four-month intervals using standardized measures of psychosocial adjustment. Results revealed that over time the families experienced significantly lower levels of illness-related demands and the marriages became better adjusted. Levels of depressive mood in the women, however, remained stable. This negative mood negatively affected the quality of the marriage, which, in turn, caused the family to cope less frequently with its problems and to function less well. Results strongly suggest the importance of formally assessing the woman's level of depressed mood and channeling women with stable depressive mood and their families into more intensive support services than those typically provided. Evidence from the current study is that, when not attended to, this depressive mood has sustained, deleterious effects on how well the family does during rehabilitation.

The functioning of single women with breast cancer and their school-aged children.

Although there are significant numbers of single women with breast cancer who are rearing children, there is no known study of their own or their school-aged children's adjustment to the illness. The purposes of this study are: 1) to describe the adjustment of single women to early stage breast cancer; 2) to contrast their responses to a comparable sample of married/partnered women; 3) and to document the psychosocial functioning of school-aged children when their single mother has breast cancer. Results obtained from questionnaire data from 22 single and 101 married/partnered women revealed that single women had significantly higher rates of depression; reported significantly higher numbers of illness-related pressures on their family; had a significantly higher proportion of young children scoring in the abnormal range on measures of self-worth and social acceptance; and reported lower quality in parenting their children. Interviews with single women revealed that many were burdened by feelings of self-deprecation because of their breast cancer, and many felt alone with the disease through the initial diagnosis period, during treatments, and through recovery. Evidence from this pilot study suggests that single women need early and immediate linkage into an informational and educational network and a viable adult support network.
