ReviewThe placebo effect: dissolving the expectancy versus conditioning debate.
The authors review the literature on the 2 main models of the placebo effect: expectancy theory and classical conditioning. A path is suggested to dissolving the theoretical impasse that has long plagued this issue. The key is to make a clear distinction between 2 questions: What factors shape placebo effects? and What learning mediates the placebo effect? The reviewed literature suggests that classical conditioning procedures are one shaping factor but that verbal information can also shape placebo effects. The literature also suggests that conditioning procedures and other sources of information sometimes shape conscious expectancies and that these expectancies mediate some placebo effects; however, in other cases conditioning procedures appear to shape placebo effects that are not mediated by conscious cognition.

Review Meta AnalysisThe affective underpinnings of job perceptions and attitudes: a meta-analytic review and integration.
Using psychometric meta-analysis, the authors present a quantitative and qualitative review (k = 205, total pairwise N = 62,527) of the literature relating trait and state positive affect (PA) and negative affect (NA) to job-related attitudes, including job satisfaction, organizational commitment, turnover intentions, and dimensions of job burnout. Results indicated substantial correlations, ranging in absolute value from -.17 (PA and turnover intentions; NA and personal accomplishment) to.54 (NA and emotional exhaustion). ⋯ Meta-analytic multiple regression results generally supported the unique contribution of each affect to each attitude variable of interest. Implications and suggestions for future research on emotion-related aspects of job attitudes are discussed.

Hypnosis has been demonstrated to reduce analogue pain, and studies on the mechanisms of laboratory pain reduction have provided useful applications to clinical populations. Studies showing central nervous system activity during hypnotic procedures offer preliminary information concerning possible physiological mechanisms of hypnotic analgesia. Randomized controlled studies with clinical populations indicate that hypnosis has a reliable and significant impact on acute procedural pain and chronic pain conditions. Methodological issues of this body of research are discussed, as are methods to better integrate hypnosis into comprehensive pain treatment.

ReviewThe psychology of doing nothing: forms of decision avoidance result from reason and emotion.
Several independent lines of research bear on the question of why individuals avoid decisions by postponing them, failing to act, or accepting the status quo. This review relates findings across several different disciplines and uncovers 4 decision avoidance effects that offer insight into this common but troubling behavior: choice deferral, status quo bias, omission bias, and inaction inertia. ⋯ Prominent components of the model include cost-benefit calculations, anticipated regret, and selection difficulty. Other factors affecting decision avoidance through these key components, such as anticipatory negative emotions, decision strategies, counterfactual thinking, and preference uncertainty, are also discussed.

Comment ReviewThe validity and appropriateness of methods, analyses, and conclusions in Rind et al. (1998): A rebuttal of victimological critique from Ondersma et al. (2001) and Dallam et al. (2001).
The authors respond to 2 victimological critiques of their 1998 meta-analysis on child sexual abuse (CSA). S. J. ⋯ Ondersma et al. (2001) claimed that Rind et al.'s study is part of a backlash against psychotherapists, that its suggestions regarding CSA definitions were extrascientific, and that the moral standard is needed to understand CSA scientifically. The authors show their suggestions to have been scientific and argue that it is Ondersma et al.'s issue-framing and moral standard that are extrascientific. This reply supports the original methods, analyses, recommendations, and conclusions of Rind et al.
