This study tested predictions of Gray's Reinforcement Sensitivity Theory (RST) in subgroups of sex offenders and male non-offenders using an experimental choice task consisting of a reward and a non-reward phase. In addition, RST-related psychometric measures were used. Both experimental and psychometric data were of interest to determine whether sex offenders could be reliably differentiated f...

We tested the hypothesis that magnitudes of sex differences in human mate preferences would be inversely related to control of resources. Specifically, we predicted that the ideal partner age, maximum and minimum partner ages tolerated and preferences for "physical attractiveness" over "good financial prospects" of female participants would approach parity with that of men with increasing contr...

OBJECTIVE To evaluate the factor structure and measurement invariance of the Diabetes Stress Questionnaire (DSQ), a measure of diabetes-specific stress, across sex, age (<9th grade vs. ≥9th grade), and glycemic control (optimal vs. suboptimal). METHODS Data from 318 adolescent participants were pooled from four archival data sets and the ongoing Predicting Resiliency in Youth with Type 1 Diab...

Female sex determination in the germ line of Drosophila melanogaster is regulated by genes functioning in the soma as well as genes that function within the germ line. Genes known or suspected to be involved in germ-line sex determination in Drosophila melanogaster have been examined to determine if they are required upstream or downstream of Sex-lethal+, a known germ-line sex determination gen...
