An example application of latent growth methodology used to analyze developmental change in adolescent alcohol consumption is presented. Findings are discussed with reference to the utility of latent growth curve models for assessing developmental processes of both the inter- and intra-individual level across a variety of behavioral domains. (SLD)

Behavior state and environmental data were collected over a 5-hour period for approximately 66 students with profound disabilities from 21 educational settings. Results showed a strong relation between different state profiles and measures of development and consistency of state patterns across chronological age levels. Results are discussed in…

The participation of the hippocampus in classical conditioning is described in terms of a multilayer network portraying stimulus configuration. A model of hippocampal function is presented, and computer simulations are used to study neural activity in the various brain areas mapped according to the model. (SLD)

The phenomena of the induction and entrainment of adjunctive behaviors was investigated in 8 people (ages 5-51) with severe or profound mental retardation who exhibited stereotypic behaviors. Seven of the eight demonstrated evidence of schedule-induced stereotypic behavior, whereas five also showed evidence of the entrainment of these behaviors by…

Examined 472 female and male undergraduates' knowledge, attitudes, and personal- and peer-use behaviors regarding drugs and alcohol. Substance use was substantial, with male use consistently exceeding female use. Examination of personal-use behaviors and attitudes revealed that students disapproved of behaviors which they themselves exhibited.…

Analysis of staff perceptions of classes of reinforcers and aberrant behaviors of 480 people with predominantly severe or profound mental retardation suggested 8 classes of reinforcers (e.g., consumable, play) and 5 classes of maladaptive behaviors (irritability, lethargy, stereotypy, hyperactivity, and inappropriate speech). Each class of…

Asked students (n=139) seeking help at university counseling center what types of problems they experienced. Found few differences between help seekers with career concerns and those without career concerns. Compared to non-help-seeking students (n=331), significantly more help seekers with career concerns indicated worrying about emotional…

The predictive validity of several theoretical factors drawn from control, social learning, and differential association theories for explaining adolescent sexual behavior was studied with 1,478 adolescents. The single factor of differential association with peers accounted for most of the respective variances on frequency of sexual intercourse…

Identifies individuals' patterns of change in behavioral approach for a single conflict along three orthogonal dimensions: attention to own-view, attention to other-view, and relational disruptiveness. Identifies general patterns of changes in individuals' conflict behaviors. (SR)

Examined the evidence for the reciprocity of negative affect between mothers and young children in disciplinary encounters. Although children responded contingently and reciprocally to maternal negativity, they also reacted negatively to maternal positive affect. (SH)

A survey of 1,482 high school students in spring and fall 1986 resulted in confirmation of the Problem Behavior Theory as a predictor of drinking and driving among adolescents. Environmental, behavioral, and demographic factors account for 50 percent of the variance in drinking and driving. (SK)

It is argued that intelligent behavior cannot be understood without reference to inhibitory processes. A review of research findings suggests that resistance to interference and the capacity for inhibition are important sources of individual differences, associated with the operation of the frontal lobes of the brain. (SLD)

Catamenial and behavioral records of nine women with mental retardation who exhibited self-injurious behavior (SIB) were analyzed for six months. Analysis confirmed that SIB was cyclic across the menstrual cycle, with the highest frequency occurring in the early follicular and late follicular phases. (Author/JDD)

The methodology of many studies that have identified specific genetic loci for disorders associated with mental retardation is criticized as failing to demonstrate an association between the behavior phenotype and the genetic marker. A more appropriate methodology using a multitrait-multimethod approach is suggested. (Author/JDD)

A taxonomy of decision behavior styles (independence/dependence, active/passive, insightful/not) tested with 372 career counseling clients was supported by similar structure analysis and confirmatory factor analysis. Counselors were more likely to be satisfied with decisions of clients they perceived to be insightful. (SK)
