The Social Sensitivity of Preschoolers in Peer Conflicts: Do Children Act Differently with Different Peers?

This study sought to demonstrate that many aspects of preschoolers' peer conflict behavior are sensitive to the subtle change in social situation that occurs when a child plays with a different partner. Twenty-seven pairs of preschoolers were videotaped over four 15-minute play sessions; in the fourth session, half of the pairs played with a different partner, while half were with the same partner. Frequency and theme of conflicts, strategies used, frequency of yielding to partner, and percentage of conflicts solved were observed. Initiating and negotiating behavior in early sessions better predicted behavior in the fourth session for the same-partner (vs. change-partner) group, and thus emerged as behaviors sensitive to social context changes. Results indicate that preschoolers have a remarkably varied array of conflict behaviors and that much of their conflict behavior is sensitive to influences inherent to social interaction with a specific partner. Ways in which the apparent sophistication in young children's social understanding can inform developmental approaches to early childhood education as well as both preventative and therapeutic conflict resolution programs are discussed.     

Part-Time Faculty in Colleges and Universities: Trends and Challenges in a Turbulent Environment

The fastest-growing group in postsecondary education is part-time faculty. The authors examine why the number of part-time faculty has increased so rapidly and then discuss some of the problems that part-timers face. Part-timers are increasing in academe, and administrators need to treat and evaluate them effectively and fairly. The authors recommend mentoring, job security, compensation, and self-worth as ways to improve performance.     

Effects of Residential Instability on Head Start Children and Their Relationships with Older Siblings: Influences of Child Emotionality and Conflict between Family Caregivers

This study examined the influence that residential dislocations have on child behavior problems, depression, peer competence, cognitive competence, and the quality of sibling relations in a sample of 70 Head Start children, aged 32 to 67 months, and their older brothers and sisters, aged 48 to 155 months. This was the first study to investigate the sibling relationship in the context of high residential mobility. Information on child characteristics was obtained from mothers and teachers. Sibling data (warmth/harmony and conflict) were obtained from coding videotaped interactions. Child emotionality was found to be an important moderator of the effects of residential mobility on young, poor children and their siblings; caregiver conflict was a less powerful moderator of these effects. Residential instability seemed to compromise the warmth/harmony of the sibling relationship. It was concluded that the effects of residential instability are complex and cannot be understood without considering child characteristics, such as temperament, and the family context in which the child lives.     

Language problems in children with learning disabilities: do they interfere with maternal communication?

In this study, parent-child interaction in two carefully matched subgroups-school-age boys with learning disabilities (LD) who showed a discrepancy between their verbal IQ and performance IQ and had more extensive difficulties in higher-level language abilities (VIQ < PIQ, n = 8) and boys with LD who did not manifest a discrepancy between verbal IQ and performance IQ (VIQ = PIQ, n = 8), were investigated. The effects of the child's language problems on child task performance and on the quality of maternal communication were analyzed in a mother-child problem solving task. Children in the VIQ < PIQ group were found to be less successful on the task than children in the VIQ = PIQ group, and their mothers exhibited lower communication clarity in their instructions than the mothers of the children in the VIQ = PIQ group. An interesting interaction effect was found for communication deviances. For mothers in the VIQ < PIQ group the extent of deficient communication increased from the monologue to the dialogue situation, whereas communication deviances decreased for mothers in the VIQ = PIQ group. Three possible models are discussed in light of the differences between the subgroups.     

Adjunct aids in instructional prose: a multimedia study with deaf college students

A computer-based science lesson was administered to 144 deaf college students grouped into low, middle, and high reading ability levels. Five instructional conditions were compared: (1) text only, (2) text and content movies, (3) text and sign movies, (4) text and adjunct questions, and (5) all of these together (full condition). The low reading level subjects in the adjunct question and full conditions demonstrated immediate, factual learning performance comparable to that of the high reading level subjects in the text-only condition. These and other results of this investigation suggest the compensatory potential of adjunct aids and associated mathemagenic activities to improve factual learning from instructional prose for low reading ability students.     

African American Fathers in Low Income, Urban Families: Development, Behavior, and Home Environment of Their Three-Year-Old Children

This study examined the relationship between paternal roles, regardless of residence, and the well-being of 175 3-year-old children from low income, African American families. There were no differences in children's cognition, receptive language, behavior, or home environment related to father presence. Fathers (or father figures) were identified in 73% of the families, and 64% participated in an interview and videotaped observation. The relationships between paternal roles (parenting satisfaction, economic support, nurturance during play, child care, and household responsibilities) and children's cognitive skills, receptive language, behavior, and home environment were examined. After controlling for maternal age, education, and parenting satisfaction, there were significant relationships between paternal roles and each index of children's well-being, suggesting that fathers' contributions were unique. Fathers who were satisfied with parenting, contributed financially to the family, and were nurturant during play had children with better cognitive and language competence; fathers who were satisfied with parenting and employed, had children with fewer behavior problems; and when fathers were living with the child, the home was more child-centered. Neither the biological relationship of the father nor the parents' marital status entered into the models. These findings support ecological theories linking paternal involvement with children's well-being and argue for the institution of family-oriented policies that promote positive father involvement.
