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…

Acquisition of verbal behavior is a major goal of interventions for children with developmental disabilities. We evaluated the effectiveness of manipulation of an establishing operation for functional discriminated mands. Four individuals with developmental disabilities participated in a training procedure designed to teach two separate mands for…

Treatment integrity refers to the degree to which an intervention is delivered as intended. Two studies evaluated the adequacy of treatment integrity procedures (including establishing, assessing, evaluating, and reporting integrity; therapist treatment adherence; and therapist competence) implemented in psychotherapy research, as well as…

Entrepreneurship is a major source of employment, economic growth, and innovation, promoting product and service quality, competition, and economic flexibility. It is also a mechanism by which many people enter the society's economic and social mainstream, aiding culture formation, population integration, and social mobility. This article aims to…

Information technology (IT) is increasingly being used to facilitate, complement, and support the implementation of evidence-based practices (EBP) in psychology. This article reviews recent randomised trials that evaluate the integration of IT applications into the process of delivering EBP. More specifically, we review 11 studies that illustrate…

Background: Accumulating evidence indicates that prenatal maternal and fetal processes can have a lasting influence on infant and child development. Results from animal models indicate that prenatal exposure to maternal stress and stress hormones has lasting consequences for development of the offspring. Few prospective studies of human pregnancy…
