Mechanisms of the relation between perinatal problems, early childhood illness, and psychopathology in late childhood and adolescence

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.     

Masculinity and femininity in twin children: genetic and environmental factors

Genetic and environmental origins of individual differences in masculine and feminine personality attributes were investigated in a sample of 38 monozygotic and 32 dizygotic twin pairs (total N = 140) during pre- and early adolescence. Self-report measures of both masculine and feminine characteristics were obtained for each child using 2 standardized instruments: the Children's Personality Attributes Questionnaire (CPAQ) and the Adolescent Self-Perception Inventory (ASPI). Multivariate biometrical analyses revealed significant genetic influences in all measures, accounting for 20%-48% of the observed variation in each. Environmental influences, which explained the remaining 52%-80% of variance in masculinity and femininity, were apparently specific to each individual and not shared by members of the same twin pair. The results underscore the importance of considering both genetic and environmental factors in gender-role development, particularly in studies of family resemblance.     

The adaptation of hearing parents of hearing-impaired youths

This study evaluated the emotional and marital adjustment of hearing parents of hearing-impaired youths. Participants included mothers and fathers of hearing-impaired youths and mothers and fathers of hearing youths. In contrast with expectations based on clinical impressions reported in the literature, parents of hearing-impaired youths reported less symptomatology than did parents of hearing youths, and there were no differences in the marital satisfaction of parents in intact families. Moreover, parental adjustment was not associated with the duration of time since the child was diagnosed as hearing impaired. In addition, hierarchical multiple regression analyses revealed that family cohesion was associated with low maternal symptomatology and high marital satisfaction for both spouses. For mothers, low symptomatology was associated with low stress and female gender of child; high marital satisfaction also was linked with a less severe degree of hearing loss in the youth.     

Developing guidelines for HIV antibody testing among victims of pediatric sexual abuse

The incidence of human immunodeficiency virus (HIV) infection acquired by children through sexual abuse is presently unknown. A telephone survey of 63 practitioners of pediatric sexual abuse (PSA) assessment in the five U.S. regions with highest prevalence of HIV infection was conducted to determine the present status of guidelines for HIV antibody testing of PSA victims. No formal protocol was used by any of those surveyed, and a literature review found no existing guidelines for HIV antibody testing of PSA victims. A standard set of clinical situations was presented to practitioners to assess whether a consensus exists of indications for HIV antibody testing of abused children. Seven clinical profiles with 12 criteria were presented including HIV antibody status, AIDS/ARC clinical profile, and behavioral profile of the assailant; clinical profile of the victim; pre-assault victim behavioral profile compatible with high risk of HIV infection (exclusively adolescents); parent/guardian anxiety/psychosocial profile; and profile of the assaultive act with respect to potential transmissibility of HIV. We found an 85% or greater consensus for 6 testing criteria, and based upon these propose an interim set of HIV antibody testing guidelines for PSA victims. There was no consensus about five testing criteria, but their frequent citation merits further consideration. Clinical application of interim guidelines and design of prospective studies to quantitatively evaluate them are reviewed.     

CS modality,context conditioning,and conditioned freezing

Two studies used a one-trial-a-day aversive conditioning procedure with rats as subjects to investigate the effects of a noise versus a light CS on conditioned freezing. Experiment 1 demonstrated that less conditioned freezing was elicited by the light, although the two CSs led to similar levels of freezing to the contextual cues of the conditioning chamber. Experiment 2 replicated these outcomes and showed that the manipulation of CS intensity produced results similar to those of modality, with the more intense CSs eliciting less freezing. The second experiment also determined that freezing to contextual cues resulted from context conditioning. According to the Rescorla-Wagner model, CSs that condition poorly should generate little competition with context conditioning. Since neither the modality nor intensity factor reliably influenced context conditioning, as measured by context-evoked freezing, the studies provide no support for the view that the effects on CS-evoked freezing represent differences in the strength of conditioning to the various stimuli. This finding raises the possibility that all of the CSs conditioned well but varied in their abilities to elicit freezing because they differed in terms of the form of defensive behavior under their control.     

An investigation of oral language and writing proficiency in third-grade students

Over the years, professionals have hypothesized that a positive relationship exists between children's oral language proficiency and their written language performance. This study examined the following two aspects of the relationship between oral and written language: (a) Are specific linguistic components of language more closely related than others? (b) Do groups rated high, medium, or low on written language measures differ significantly in oral language proficiency? Measures of oral and written language were administered to 77 third-grade students. Results indicated that moderate relationships existed between grammatical aspects of oral and written language. Oral language proficiency was significantly different for groups rated high, medium, and low on the basis of written language performance.
