... Both these aspects are critical in understanding expectancy mediation, for even if we could show an enormous effect of expectancy on expecter behavior (e.g., teachers smile more at high expectancy students) , that behavior would not be important in expectancy mediation unless it actually impacted on the expectee to create better outcomes (e.g., being smiled at leads to better grades)

... We then computed an overall significance level and effect size for each of the 31 categories, separately for the expectancy-behavior effects and the behavior-outcome effects. The results of this meta-analysis pointed to the practical importance of 16 behaviors in mediation: negative climate, physical distance, input,

... offer opinions about the extent to which expectancy effects may be influencing research results in these areas. The five areas that will be covered are those targeted for evaluation by the Committee on Techniques for the Enhancement of Human Performance; these areas are research on accelerated learning, neurolinguistic programming, mental practice, biofeedback, and parapsychology.
