Research in recent years, especially in the analgesic field, has intensively studied the placebo effect and its mechanisms. It has been shown that physical complaints can be efficiently reduced via learning and cognitive processes (conditioning and expectancies). However, despite evidence demonstrating a large variety of physiological similarities between pain and itch, the possible transfer of the analgesic placebo model to itch has not yet been widely discussed in research. This review therefore aims at highlighting potential transfers of placebo mechanisms to itch processes by demonstrating the therapeutic issues in pharmacological treatments for pruritus on a physiological basis and by discussing the impact of psychological mechanisms and psychological factors influencing itch sensations.

Abstract. The purpose of this study was to test for race and sex differences in general mental ability (GMA) retest performance and to identify the psychological mechanisms underlying these differences. An initial and retest administration of a GMA assessment separated by a six-week span was completed by 318 participants. Contrary to our predictions, we found that race, sex, and emotional stability failed to moderate GMA retest performance. However, GMA assessed via another ability test and conscientiousness both partially explained retest performance. Additionally, we found that retesting may reduce adverse impact ratios by lowering the hiring threshold. Ultimately, our findings reinforce the need for organizations to consider race, sex, ability, and personality when implementing retesting procedures.
