Emotional reactivity and expressivity in infants have been previously correlated with vagal tone. This study investigated vagal tone of 3- and 6-month-old infants of depressed mothers. Vagal tone did not differ for infants of depressed versus nondepressed mothers at 3 months, but lower vagal tone was noted in infants of depressed versus nondepressed mothers at 6 months. The developmental increase in vagal tone that occurred between 3 and 6 months for infants of nondepressed mothers did not occur for infants of depressed mothers. Correlation analyses suggested that higher vagal tone at 6 months was related to more vocalizations and more optimal neurological scores.

Previous studies have reported significant associations between measures of the family environment and behavior problems in children. However, because children in these studies were genetically related to their parents, such links may not be caused solely by environmental influences. The goal of this study was to investigate genetic influence on associations between family environment and problem behavior using an adoption design. Participants in the study included 179 adopted and 176 nonadopted children, as well as their parents and teachers, in the Colorado Adoption Project (CAP; Plomin, DeFries, & Fulker, 1988). Mothers and fathers each completed the Family Environment Scale (FES) when their child was 1, 3, and 5 years of age; the child's problem behavior at age 7 was rated by both mothers and teachers using the Child Behavior Checklist (CBCL). Patterns of correlations for nonadopted versus adopted boys indicated that associations between aspects of the family's relationship (conflict, cohesion, expressiveness) and behavior problems in home and school were mediated genetically. For girls, however, these links appeared to be influenced by direct shared environmental effects.

The role of attachment in interaction with other relationships and conditions was investigated in relation to children's later psychosocial development (at ages 6 and 9). Thirty-nine unipolar depressed mothers, 24 bipolar mothers, and 32 normal control mothers and their children were studied. The network of conditions defining early experience included, in addition to attachment, maternal psychopathology, marital discord, other disordered relationships in the family, and recent losses of significant persons. Patterns of mother-child interaction were also examined. Assessments of children's problems were based on psychiatric evaluations of depressive affect, anxiety, and disruptive-oppositional behavior.

The findings support the conclusion that attachment enters into development in interaction with other relationships and conditions. Maternal psychopathology, in particular, in interaction with the attachment relationship, is linked to later developmental outcomes. The importance of considering mother-child interactional and dispositional characteristics is indicated. The early attachment relationship together with the ways in which the mother's depression is expressed with her child, and the child's style of coping with the mother's functioning establish patterns of behavior that influence the child's vulnerability to later problems. Multiple pathways of transmission of affective problems are discussed.

Analysis of longitudinal data for 145 children [51 healthy, 40 with cystic fibrosis (CF), and 54 with congenital heart disease (CHD)] was conducted: (a) to ascertain whether behavioral problems evident in older medically compromised children would be reported as early as 2–3 years-of-age; and (b) to test theoretical predictions concerning the role of infant-mother attachment in the etiology of behavior problems. As predicted, children with a medical diagnosis received higher scores from parents on the Child Behavior Checklist (CBCL), primarily on the Internalizing scale. Reports of somatic symptoms did not account for this effect. Contrary to predictions, children with CHD were reported to have more behavior problems than those with CF. Secure attachment was associated with lower CBCL scores for internalizing problems regardless of medical status. The increase in behavior problem reports associated with insecure attachment was shown to reflect an effect of avoidance rather than insecurity per se. The importance of distinguishing effects of different types of insecurity and the need for meta-analytic strategies to do so is emphasized.

Attachment security was assessed in children who had spent at least 8 months in a Romanian orphanage (RO) and two comparison groups of children: a Canadian-born, nonadopted comparison group (CB) and a comparison group adopted from Romania before the age of 4 months (RC). We also assessed differences in displays of indiscriminately friendly behavior between the two adopted groups of children. Attachment security was assessed using parent report on a questionnaire comprised of the 23 items with the highest and lowest loadings on the Waters and Deane (1985) attachment Q-sort. Indiscriminately friendly behavior was assessed using parents' responses to five questions about their children's behavior with new adults. Children's attachment security scores were also compared to parents' scores on the parent attachment subscale of the Parenting Stress Index (Abidin, 1990). RO children scored significantly lower on security of attachment than did either the RC or CB children. RC and CB children did not differ on attachment security. Based on their parents' reports, RO children displayed significantly more indiscriminately friendly behaviors than did RC children, but such behaviors were not correlated with security of attachment. Children's attachment security scores were related to their parents attachment scores only in the RO group. It is suggested that RO children's experience of extreme neglect contributed to their low attachment-security scores, and that indiscriminate friendliness may be an important behavior to consider in the study of attachment in institutionalized children.

Teacher reports of children's competence and problem behaviors are an important source of information on psychopathology. The school context is also an agent of developmental change. This study examines teacherchild relationships and deflections in child adjustment over the school-entry to grade 2 period in 436 children. The Student-Teacher Relationship Scale (STRS) was related to two indices of deflections in predicted child adjustment: (a) residual scores obtained from regressing teacher reports from grade 1 on kindergarten teacher reports, and (b) false positive predictions of retention or referral for special education in the K-l period.

Children with whom kindergarten teachers reported a positive relationship were rated in spring of grade I as better adjusted than was predicted on the basis of identical ratings from the fall of the kindergarten year; the converse was also true. False-positive retention/referral predictions had more positive relationships with kindergarten teachers than did true positives. A second set of analyses examined second grade teacher ratings of child adjustment and child-teacher relationships in two groups of children with different child-teacher relationship histories in kindergarten. Children with warm, close, communicative relationships with kindergarten teachers were better adjusted and had more positive child-teacher relationships in second grade than those with angry, dependent child-teacher relationships in kindergarten. Results supported the view that children's relationships with teachers are an important component of adaptation in school, and that they can play a role in deflecting the course of development in the school context.

In recent research a relationally oriented form of aggression has been identified that, in contrast to overt aggression that harms others through physical means (e.g., hitting), harms others through damage to their peer relationships (e.g., angrily retaliating against a peer by excluding her from one's play group). The goal this research was to assess the role of intent attributions, feelings of distress, and provocation type (relational vs. instrumental) in children's relationally aggressive behavior. A total of 252 third- through sixth-grade children participated as subjects. A hypothetical provocation instrument was used to assess children's intent attributions and feelings of distress for ambiguous relational and instrumental provocation situations. Results showed that, as hypothesized, relationally aggressive children exhibited a hostile attributional bias and reported significantly higher levels of distress than did their nonaggressive peers for relational provocation situations. In addition, girls reported significantly higher levels of distress than did boys for relational provocation situations. Further, a comorbid group of relationally plus overtly aggressive children also exhibited a hostile attributional bias; however, their bias was evident for instrumental provocation situations only.

The purpose of this investigation was to contrast the social competencies of groups of extremely withdrawn and average children. Fifty-five kindergarten, Grade 2 and Grade 4 children were observed during dyadic play in a laboratory setting. Results indicated that (a) withdrawn children displayed fewer social problem-solving initiations, produced fewer socially assertive strategies, and were less successful in their attempts, compared to their more sociable age-mates; (b) average children experienced fewer failures in meeting their social goals with increasing age but withdrawn children did not; (c) the discrepancy in failure rates for “high cost” social goals between the two target groups increased with increasing age; and (d) withdrawn children were less likely than average children to reinitiate a social problem-solving attempt subsequent to failure.

Fifty-seven extremely shy-inhibited children, 59 extremely aggressive children, and 352 of their average counterparts, 8 and 10 years-of-age, residing in Shanghai, the People's Republic of China, were compared on sociometric nominations of peer acceptance and rejection, teachers' assessments of school related competencies, a self-report measure of depression, and Chinese measures of normative school behavior, honorship, leadership, and academic achievement. The results indicated that, as in the Western literature, aggressive children in China were more likely to have difficulties in adjustment than their average age-mates. Inconsistent with the results in Western literature, shy-inhibited children in China were found to be more accepted by peers than their average age-mates. Furthermore, compared with the average and aggressive children, shy-inhibited children were most likely to be considered for honorship and leadership positions and were regarded by teachers as the most competent in school. Finally, the three comparison groups did not differ on a measure of depression. Children in China, however, evidenced higher depression scores than a comparison group in the West. Given these findings, it seems to be important to examine, in the future, the processes of socialization that lead to social adjustment and maladjustment of shy-inhibited and aggressivedisruptive children in non-Western cultures.

Shifts in covert visual attention were compared in children with and without Attention Deficit Hyperactivity Disorder (ADHD) to determine if children with ADHD have developmental immaturities in covert attention, relative to their non-ADHD peers. Children were told to orient attention to a central fixation point and were then cued, by both central and peripheral cues, to direct their attention to either the left or right peripheral fields. Following variable time intervals, the target appeared and reaction times and errors were recorded. Although performance of all subjects showed faciliation when attention was directed by valid cues and inhibition when attention was directed by invalid cues, the performance of children with ADHD was far more disrupted when their attention was misled by invalid cues, especially at longer intervals. This inconsistency was reflected in significantly higher error rates in the ADHD group. They also showed a pattern of attentional “waxing and waning” in performance over longer time intervals that has been previously found in auditory attention switching over time within trials in children with ADHD. Overall, results are inconsistent with developmentally immature covert attention skills in ADHD. Findings are discussed in terms of the concept of global “developmental immaturity” in the attention skills of children with ADHD.

Self-instructional training, a widely used intervention for treating the learning and behavioral difficulties of impulsive, attention deficit-hyperactivity disordered, and learning disabled children, has repeatedly failed to promote self-control or improve academic performance. In light of this failure, we critically examine four assumptions underlying self-instructional training: (a) children with learning and behavior problems show a lack and/or deficient use of self-regulatory private speech; (b) modeling of self-verbalizations will increase children's spontaneous production of private speech; (c) speech and action are intrinsically coordinated; and (d) internalization refers to subvocalization of private speech. We argue that self-instructional training interventions need to be thoroughly grounded in Soviet developmental theory of verbal self-regulation and in systematic research on the social origins and development of children's private speech. A new research agenda is suggested.
