Purdue Pegboard: test-retest estimates.

26 normal, self-reported dextral subjects (12 men, 14 women) were assessed with a Purdue Pegboard 5 times at weekly intervals to evaluate temporal stability and efficacy of lateralization with this test. There was a statistically significant increase in performance over time for men on the right- and left-hand placing subtests and for women on the assemblies subtest. For men/women the test-retest reliability over the 5 sessions averaged .63/.76 for the right-hand, .64/.79 for the left-hand, .67/.81 for both-hands, .81/.83 for assemblies, and .33/.22 for the right/left-hand ratio.

Normative data for the Halstead-Reitan neuropsychological tests stratified by age and sex.

Normative data, stratified by age and sex, are presented for the Halstead-Reitan neuropsychological tests: Name Writing, Speech-Sounds Perception, Trail Making, Halstead Category, Finger Tapping, Dynamometer, Tactual Performance, Seashore Rhythm, Tactile Form Recognition, Finger-Tip Number Writing Perception, Face-Hand, and Finger Localization. Correlations of the test variables with age, education, and WAIS-R Verbal and Performance IQ are reported. The normative sample consisted of 225 adults (127 males, 98 females) 15 to 40 years of age. The subjects who were included did not report any history of forensic involvement, head injury, neurological insult, prenatal or birth complication, psychiatric problems, or substance abuse.

Stimuli eliciting sexual arousal in genital exhibitionists: a possible clinical application.

The sexually arousing effects of erotic and nonerotic slides were monitored with a penile mercury strain gauge in 14 exhibitionists, 21 normal controls, and 34 nonexhibitionist sex offenders. Responses to 60 slides, constituting 12 distinct categories, were analyzed. The exhibitionists responded sexually to scenes of fully clothed erotically neutral females, whereas the two control groups did not respond to this slide material. No other significant differences were observed between the three groups on the remaining 11 categories. The results support previous reports of sexual arousal in exhibitionists to nonerotic signals from females and are consistent with a hypothesis of exhibitionists displaying culturally unapproved sexual display signals as a consequence of cortical disinhibition.

Finger tapping: effects of trials and sessions.

18 normal, self-reported dextral subjects (9 men, 9 women) were assessed with a Halstead Manual Finger Tapping device, with 10 trials per hand for 10 consecutive wk. The test-retest reliability of the 10-trial average between the 10 sessions averaged .94 for men and .86 for women, for both preferred and nonpreferred hands. There were no statistically significant effects of increases in performance over sessions or effects of fatigue over trials for either sex or hand. There were, however, significant increases over trials for men for both preferred and nonpreferred hands.

Hand dynamometer: effects of trials and sessions.

12 normal, self-reported dextral subjects (6 men, 6 women) were assessed with a hand dynamometer with 10 trials per hand for 10 consecutive wk. The test-retest reliability of the 10-trial average across the 10 sessions averaged .91 for men and .94 for women for both preferred and nonpreferred hands. Fatigue effects over trials were statistically significant for both sexes and hands except for women's preferred hand. Skill acquisition effects over sessions were only statistically significant for men's nonpreferred and women's preferred hands.

The measurement of intimacy in marriage: the Waring Intimacy Questionnaire.

Developed eight independent content scales to assess components of marital intimacy (Conflict Resolution, Affection, Cohesion, Sexuality, Identity, Compatibility, Autonomy, and Expressiveness). The measures were designed to be relatively free from social desirability and acquiescent responding (N = 248). Test retest and internal consistency reliabilities were high and sexual bias was not indicated.
