Researchers manipulate time perceptions in experiments, but the efficacy of such manipulations demands further scrutiny. Two studies test the effects of dispositional time views and time view manipulations on product attribute evaluations, as well as the interaction between cognitive age and manipulated time perceptions and that between dispositional and manipulated time perceptions. The results suggest that time manipulation drives and predicts consumer product evaluations. In addition, cognitive age interacts with time manipulation as a meaningful moderator/predictor, and dispositional time view interacts with time manipulation to influence consumer evaluations. An incongruency effect (i.e., a time manipulation condition that differs from consumers' time perceptions) occurs for hedonic attribute evaluations but not for utilitarian attribute evaluations. The research offers several managerial implications of these findings.
