Attributions of deception as a function of reward value: A test of two explanations

Nonverbal expectancy violations theory and a cognitive heuristics approach were used to generate predictions regarding attributions of deception directed toward a message source. The appearance of a message source was manipulated to be either higher or lower in attractiveness while engaging in stereotypically deceptive or truthful behavior. A heuristic approach would suggest a main effect for attractiveness on deceptiveness attributions while a nonverbal expectancy violations approach would predict an interaction between the attraction and deception manipulations. An apparent main effect suggested that the more socially attractive message source was perceived to be less deceptive. However, the effect was driven by an interaction that showed the discrepancy in deception attributions between levels of attractiveness was highest in the deceptive behavior condition, as predicted by nonverbal expectancy violations.
