ABSTRACT
The intrapersonal and interpersonal expectancy effects have their positive and negative varieties, a kind of obverse and reverse. In relation to emotional processes, disconfirmation of positive intra- and interpersonal expectancies is usually a source of negative effect. If the cited analogy is not accidental, then it seems reasonable to hypothesize that at the root of types of expectancy effects there are similar cognitive, emotional, and behavioral mechanisms and processes. The cognitive and affective processes which specificity is determined by the level of expectancy confirmation influence a person's behavioral responses to oneself and to his or her interaction partners. Considering the former possibility, it seems particularly interesting to try to analyze the process of creating a self-fulfilling prophecy within the model of formation of intrapersonal expectancies. Kirsch has suggested that changes in anxiety may be a mediating mechanism between expectancy and placebo effects.
