Physical child abuse: A dual-component analysis

Previous etiological models of child abuse are reviewed, with particular emphasis on the current social interactional analysis. It is argued that while this model accounts for the documented correlates of abuse, it fails to provide a plausible mechanism for explaining the rapid acceleration from low- to high-intensity punitive behavior characteristic of abusive episodes. Drawing from research on interpersonal aggression by Berkowitz, Zillmann, and other social psychologists, a model is developed in which an arousal-mediated respondent component is added to the current instrumentally based punitive processes. Implications of this improved analysis for treatment and prevention are considered.     

Application of the generalized matching law to point-after-touchdown conversions and kicker selection in college football

Coaches make a variety of complex decisions in American-rules college football, especially related to point-after-touchdown (PAT) conversions and, historically, kicker selection. However, little research has characterized the pattern of these choices and whether they are sensitive to environmental manipulations, such as increased effort to score. In the present study, the generalized matching law (GML)—a model that predicts a linear relation between log-transformed choices for two alternatives and the amount of reinforcement garnered from them—was applied to PAT-conversion (1 point vs. 2 point) and kicker (soccer-style vs. conventional-style) selection using archived data from the National Collegiate Athletic Association. Overall, PAT-conversion and kicker selection exhibited matching. Further, narrowing the goal-post width was associated with decreased preference for one-point (relative to two-point) PAT attempts and enhanced sensitivity to increases in points scored from one-point (relative to two-point) PAT attempts. This investigation provides support for the ecological validity of the GML and demonstrates that complex decisions in football conform to an orderly pattern that can be described using the GML.
