The authors conducted a Monte Carlo simulation of 8 statistical tests for comparing dependent zero-order correlations. In particular, they evaluated the Type I error rates and power of a number of test statistics for sample sizes (Ns) of 20, 50, 100, and 300 under 3 different population distributions (normal, uniform, and exponential). For the Type I error(More)
One hundred eighty-eight drug-abusing and conduct-disordered adolescents and their parents provided retrospective reports of the youths' frequency of alcohol and illicit drug use for each of the 6 months preceding their initial session in an outpatient treatment program. Youths' and parent reports of youths' drug and alcohol use for each month were similar.(More)
Previous research has examined the connoted hazard of various colour and signal words separately. The purpose of the present research was to examine the interaction of signal words and colours. Two separate experiments examined the influence of colour on perceptions of hazard and on compliance to printed warnings. In experiment 1, a sample of 30(More)
The purpose of the study was to assess differences in color preferences between the sexes. A sample of 193 retirees were asked to report their favorite colors.

On the evening of November 8, 1988, I was working with my colleague Gary King in his Harvard office. Gary somehow had gotten his hands on a pair of tickets to Michael Dukakis's victory party in Boston, and we were trying to decide whether to go. Dukakis was expected to lose, but. .. who could say, right? We had the TV on, and the first state to report, at(More)
Health intervention outcomes are often assessed as binomially distributed variables. In designing such interventions it is important to model the pre-intervention rate of the target behavior when performing sample size calculations. Unfortunately, the majority of sample size programs model post-intervention outcomes only, which results in exaggerated sample(More)

Research dealing with attitudes toward women comparing black and white, male and female university students has had mixed results, but research on this topic has used a variety of measures. This study used black (N=162) and white (N=155) college students who completed Spence and Helmreich's 15-item Attitudes toward Women Scale which considers women's roles(More)
The Sport Interference Checklist (SIC) was developed in 141 athletes to assist in the concurrent assessment of cognitive and behavioral problems experienced by athletes in both training (Problems in Sports Training Scale, PSTS) and competition (Problems in Sports Competition Scale, PSCS). An additional scale (Desire for Sport Psychology Scale, DSPS) was(More)
