Visual representation of interaction effects between expectation-related contrasts and physical self-concept on perceived exertion.
Conditional effects of (A) experimental conditions 1 and 2 (induced positive expectations) versus Control 1 (Contrast 1), (B) experimental conditions 1 and 2 (induced positive expectations) versus Control 2 (Contrast 2) and (C) Experimental 1 (Shirt and Exercise-Effect Expectation) versus Experimental 2 (Exercise-Effect Expectation) (Contrast 3) on perceived exertion among participants with high (mean + 1 SD), medium (mean), and low physical self-concept (mean—1 SD). Endpoints represent estimated means of perceived exertion for these moderator levels, controlled for habitual expectation and baseline perceived exertion. Significant simple slopes are indicated (for [B] on the level of high physical self-concept, for [C] on the level of low physical self-concept). All figures are based on N = 76.
