Eyewitness misidentification: single vs. double-blind comparison of photospread administration.

Interactive effects of photospread procedures (blind administration or has knowledge of suspect identity) and presentation techniques (sequential or simultaneous photospreads) on false eyewitness identification rates were examined. Of 117 subjects (57 men and 60 women), 87 served as a witness sample and 30 as a photospread administrator sample. Witnesses viewed a 20-sec.

Effects of humor on test anxiety and performance.

The present study evaluated the moderating effects of humor in test items on the hypothesized relationship between test anxiety and performance. Subjects initially completed anxiety scales, as well as coping-humor and sense-of-humor scales. 34 women and 26 men received achievement tests under one of three test conditions: (1) nonhumorous, (2) low-humor (15% of test items), or (3) moderate-humor (30% of test items).

The effects of women's age and physical appearance on evaluations of attractiveness and social desirability.

Younger people are perceived as possessing a host of socially desirable attributes, some of which are the same traits attributed to attractive people. In the present study, 160 younger and older White Canadians rated the attractiveness and personality traits of 1 of 4 target women. The results indicated an interaction between the participant's age and gender and the age and attractiveness of the target person.

Feedback and self-efficacy, arousal, and performance of introverts and extraverts.

Research has suggested that introverts and extraverts differ in their responses to performance feedback. The present study examined the effect on introverts and extraverts of a short-term memory task. Subjects (ns = 8) were randomly assigned to one of three feedback conditions: positive, negative, or control.

EEG alpha methodologies and hypnotizability: a critical review.

This paper reviews empirical studies that assessed the relationship between EEG alpha indices and measures of hypnotic responding. Although there are confirmatory reports of such a relationship, these findings have not been corroborated in repeated attempts at replication. The research is characterized by poor design and statistical procedures that fail to control for various extraneous factors.
