Bidirectional Effects of Parenting Quality and Child Externalizing Behavior in Predominantly Single Parent, Under-Resourced African American Families

This study investigates the bidirectional perspective of parent–child effects by examining the extent to which parenting quality predicted child externalizing behavior and vice versa. Data was collected over four time points from primary caregivers and early school age children in low-income, primarily single parent homes (N = 249, mean age of children at Time 1 = 6.41 years). Parenting quality was operationalized as primary caregiver perceptions of positive parenting, effectiveness of parenting discipline, parenting efficacy and satisfaction. Child externalizing behavior data was captured via an assessment of the frequency of externalizing behavior as reported by caregivers. We hypothesized that parenting quality and child externalizing behavior would remain stable over time and that a bidirectional relationship would be present. Data was analyzed using structural equation modeling and results indicated that child externalizing behavior predicted subsequent parenting quality, and parenting quality predicted subsequent child externalizing. Specifically, our research team found that the influence of child externalizing behavior on parenting quality decreased with time, while the influence of parenting quality on child externalizing behavior increased with time. Overall results reveal the complex transactional influences of child externalizing behavior and parenting quality in our sample. Findings support the notion that parenting quality and child externalizing behavior are interactive processes which might best be handled by continual assessment and which may be potentially strong targets for interventions.     

Learning to program in LISP

We have gathered protocols of subjects in their first 30 hours of learning LISP. The processes by which subjects write LISP functions to meet problem specifications has been modeled in a simulation program called GRAPES (Goal Restricted Production System). The GRAPES system embodies the goal-restricted architecture for production systems as specified in the ACT* theory (Anderson, 1983). We compare our simulation to human protocols on a number of problems. GRAPES simulates the top-down, depth-first flow of control exhibited by subjects and produces code very similar to subject code. Special attention is given to modeling student solutions by analogy, how students learn from doing, and how failures of working memory affect the course of problem-solving. Of major concern is the process by which GRAPES compiles operators in solving one problem to facilitate the solution of later problems.     

Comparative Psychopathology of Suicide Attempts and Assaults

ABSTRACT: Using the Katz Adjustment Scales to measure psycho-pathology, systematic samples of 108 suicide attempters and 42 persons arrested for assault were tested in Baltimore, Maryland. The subjects' scores were compared with ratings by third-party respondents, who knew the subjects well, and with scores of 450 controls. Both suicide attempters and assaulters displayed significantly more psychopathology than the controls. The suicide attempters were differentiated from the assaulters on six Katz items: Helplessness, Anxiety, Nervousness, Depression, Stability, and General Psychopathology. An attempt was made to refine prediction and control of these two different life-threatening behaviors by interpreting the data in terms of Henry and Short's concept of “internal restraint.”
