Integrative hierarchical models have sought to account for the extensive comorbidity between various internalizing disorders in terms of broad individual difference factors these disorders share. However, such models have been developed largely on the basis of self-report and diagnostic symptom data. Toward the goal of linking such models to…

Procedures are proposed for increasing the accuracy of generalization assessment in applied behavior analysis with behavior problem populations by accounting for the degree of natural covariation between treated and untreated behaviors. (Author/DB)

A program of self-instructional research is presented which incorporates the perspective that developmental theories may be used to understand and design interventions to remediate dysfunctional behavior in children. This is followed by recent applications of this program to the issue of impulsivity. (Author/GK)

Discusses behavioral momentum and the general behavioral relation between the persistence of behavior and the rate of reinforcement obtained in a given situation. Strategies for establishing the generality of behavioral relations are reviewed, followed by a brief summary of evidence for the generality of behavioral momentum. (Author/CR)

This commentary on EC 608 301 points out that devotion to the natural science canon of experimental proof in the area of generality testing requires proof procedures that are difficult, expensive, or impossible, but adopting a different canon of proof will not produce the desired certainty about the accuracy of the answer.
