In a previous article, we provided a review of the literature pertaining to the potential misdiagnosis of giftedness as ADHD, as well as a small-scale study to illustrate this potential misdiagnosis. In this issue of "Roeper Review," Mika provides several criticisms of that paper. In this article, we provide responses to her arguments by…

Although filmmaking requires substantial capital investment, it is not known whether cinematic creativity is positively correlated with the size of the film's budget. Therefore, budgetary impact was investigated in a sample of feature films released between 1997 and 2001. Although production costs were positively related to box office success (as…

Joint attention skills are an important part of human cultural learning. However, little is known about the emergence and meaning of these skills in early ontogeny. The development of, and relation among, various joint attention skills was assessed. Seventy-two 5 to 10-month-old infants were tested on a variety of joint attention tasks.…

The purpose of the current study was to test whether perceived peer influence is related to image of a typical smoker, and whether image of a typical smoker is associated with beliefs about the effects of smoking among preadolescent nonsmokers. Two hundred and ninety-two preadolescents completed a survey indicating their perceptions of the…

The sensitivity of the Paced Auditory Serial Addition Task (PASAT) to working memory deficits may be enhanced by examining "dyads" (i.e., correct responses immediately preceded by a correct response) as a complement to the traditional total correct summary score. In a sample of 397 mostly African American (79%) healthy adults, total dyad…

This article proposes alternative expressions for the two most prevailing definitions of suppression without resorting to the standardized regression modeling. The formulation provides a simple basis for the examination of their relationship. For the two-predictor regression, the author demonstrates that the previous results in the literature are…

Multilevel modeling is an increasingly popular technique for analyzing hierarchical data. This article addresses the problem of predicting a future observable y[subscript *j] in the jth group of a hierarchical data set. Three prediction rules are considered and several analytical results on the relative performance of these prediction rules are…

This study examines the question Does the rate of currently divorced in counties in the United States vary inversely to the relative percentage of concentration of adherents of seven different religious denominational groupings--Catholic, Jewish, Mormon, conservative Protestant, moderate Protestant, liberal Protestant, and miscellaneous…

Meta-analytic structural equation modeling (MA-SEM) is increasingly being used to assess model-fit for variables' interrelations synthesized across studies. MA-SEM researchers have analyzed synthesized correlation matrices using structural equation modeling (SEM) estimation that is designed for covariance matrices. This can produce incorrect…

This study examines the relationship between achievement goals and some important learning-related variables in the completion of a course assignment. The research on achievement goals is reviewed and two contentious issues--the nature of performance goals and the effects of multiple goals--are highlighted. Three hundred and seventy-three Chinese…

We argue that the report by Templer and Arikawa contains misleading conclusions and is based upon faulty collection and analysis of data. The report fails to hold up for quality of data, statistical analysis, and the logic of science.

In 1992, Reed and Jensen ["Intelligence" 16 (1992) 259-272] reported a positive correlation (0.26; "p"= 0.002; 0.37 after correcting for restricted intelligence range) between a brain nerve conduction velocity (NCV) and intelligence level in 147 normal male students. In the first follow-up of their study, we report on a study…

Raven's matrices and inspection time (IT) were recorded from 56 subjects under five arousal levels. Raven's and IT correlated strongly (r = -0.7) as predicted by processing-speed theories of "g." In line with Eysenck's [Eysenck, H. J. (1967). "The biological basis of personality". Springfield, IL: Thomas] arousal theory of extraversion, there was…

This study attempted to increase the size of the correlation between person-environment (P-E) fit and job satisfaction by rescaling the instrumentation of the Theory of Work Adjustment using the Bradley-Terry-Luce method and a probability-based fit index. This approach worked as well as, but failed to outperform, the currently used…

Past research has shown that self-defense/assertiveness training may have positive implications for sexual assault survivors. However, little is known about the correlates of self-defense/assertiveness training participation for sexually victimized women. In this study we examined the assault characteristics and experiences that relate to women's…
