Previous studies have shown a low rate of engagement in pleasant activities to be a concomitant of depression. The crucial question addressed by the Hammen and Glass study (1975) is whether an increase in pleasant-activity level will produce a decrease in depression level. (Editor)

This paper reviewed the original spreading-activation theory developed by M. R. Quillan while trying to correct some common misunderstandings concerning it. It extended the theory in several respects, showed how the extended theory dealt with recent experimental findings, and compared it to the model of Smith, Shoben, and Rips (1974). (Author/RK)

This article deals with the psychological consequences of immoral actions, and reviews research on the psychological effects on adults of such transgressions as lying, cheating, and inflicting pain purposely rather than by accident. (MP)

Developing a Suicide Potential Scale for a number of socially differentiated, stratified census tract populations in a northern city, this paper argues that scores on this scale are related to actual suicidal behavior. These data support the position that variation in suicide among blacks is mainly determined by economic status. (Author)

This study explored anomic and egoistic dimensions of contemplated suicide among voluntary and involuntary retired males. Results indicated a direct relationship between anomie and egoism on the one hand, and contemplation of suicide on the other. (Author)

This article is a first step toward the construction of random measurement theories. A random version of additive conjoint measurement is proposed and developed in detail. (Editor)

This paper discusses the existence of theoretical distributions subsumed within mathematical reality and it highlights several meaningful implications for psychological researchers to consider in the application of statistical procedures. It begins with a brief overview of the misinterpretation of statistical testing, followed by a discussion of…

This paper reviews the basics of the elusive but important concept of the interaction effect. The analysis of variance (ANOVA) interaction effect is defined both conceptually and mathematically. Common errors in interpreting interaction effects are discussed, and appropriate strategies for achieving post hoc understandings of the origin of…
