Compared the traditional moderated regression technique with a technique designed to increase the probability of indication of a moderator variable. Results indicated that detection of moderator variables is dependent on their strength. A higher probability of detecting a moderator exists if the interaction is entered into the regression first.…

The author makes a plea to both academics and managers to consider the price business pays for applying universal theories in particular situations and asks each to take a role in rectifying the situation. (Author/IRT)

Gilbert Gottlieb's theory of probabilistic epigenesis replaced the nature-nurture dichotomy, and similar oppositions, with an integrated account of the development of the entire behavioral phenotype. In that theory, invariant developmental outcomes cannot be identified with an organism's 'nature,' if by that term is meant a set of predetermined…

When behavior suggests that the value of a reinforcer depends inversely on the value of the events that precede or follow it, the behavior has been described as a "contrast" effect. Three major forms of contrast have been studied: "incentive contrast," in which a downward (or upward) shift in the magnitude of reinforcement produces a relatively…

Mice from replicate lines, selectively bred based on high daily wheel-running rates, run more total revolutions and at higher average speeds than do mice from nonselected control lines. Based on this difference it was assumed that selected mice would find the opportunity to run in a wheel a more efficacious consequence. To assess this assumption…

Chomsky's (1959) review of Skinner's (1957) "Verbal Behavior" has been influential and attributed with a role in the cognitive revolution. However, while counter reviews from within behavior analysis have noted that Chomsky misunderstood the subject matter, certain aspects of his scholarship have been underdiscussed. This includes several…

The authors examined the structural validity of the parent informant version of the Strengths and Difficulties Questionnaire (SDQ) with a sample of 733 custodial grandparents. Three models of the SDQ's factor structure were evaluated with confirmatory factor analysis based on the item covariance matrix. Although indices of fit were good across all…

The growing Hispanic population has come into increasing contact with the larger population of non-Hispanic Whites. It is important to understand the effects of this contact on prejudice. The effects of six kinds of contact were examined for their effects on prejudice between Hispanics (n = 156) and non-Hispanic Whites (n = 1,479) who were…

Previous reports have shown that overexpression of the growth- and plasticity-associated protein GAP-43 improves memory. However, the relation between the levels of this protein to memory enhancement remains unknown. Here, we studied this issue in transgenic mice (G-Phos) overexpressing native, chick GAP-43. These G-Phos mice could be divided at…

Stimulation paradigms that induce perforant path long-term potentiation (LTP) initiate phosphorylation of ERK1/2 and induce expression of a variety of immediate early genes (IEGs). These events are thought to be critical components of the mechanism for establishing the changes in synaptic efficacy that endure for hours or longer. Here we show that…

Cultural meanings (e.g. the green eyed monster) and research interests have traditionally focused on female jealousy. In contrast, this research focused on male jealousy. Two-hundred ninety-one undergraduates at a large southeastern university completed a confidential, anonymous forty-four-item questionnaire on jealousy. Men reacted differently…

The central messages of this paper are that (a) unequal variances may be more prevalent than typically imagined in educational and policy research, and (b) when considering tests of equal variances one needs to be cautious about what is being referred to as "Levene's test" because Levene's test is actually a family of techniques. Depending on…

Despite several decades of research suggesting the importance of both genetic and environmental factors, these findings are not well integrated into the larger educational literature. Following a discussion of quantitative and molecular genetic methods, this article reviews behavioral genetic findings related to cognitive and academic skills. This…

Bockenholt and van der Heijden's results regarding compliance with insurance regulations--that the enforcement activities of a regulatory agency were relatively unpredictive of compliance--are consistent with findings from other domains (e.g., tax adherence), where personal factors and informal social controls have been shown to play a more…

Despite contradictory findings, the belief that psychotherapy promotes survival in people who have been diagnosed with cancer has persisted since the seminal study by D. Spiegel, J. R. Bloom, H. C. Kramer, and E. Gottheil (1989). The current authors provide a systematic critical review of the relevant literature. In doing so, they introduce some…
