This study examines some specific effects of the Positive and Negative Velten Mood Induction Procedures and of two motion pictures selected for their affect inducing qualities. Results revealed that, despite apparently strong effects on affective state when measured immediately after affect induction, the Velten Statements and one of the films had no discernible effect when measured after a brief, neutral, intervening task. The other film, in contrast, appeared to influence affective state not only when tested immediately, but even after the intervening task. These results were interpreted as shedding additional light on the affect inductions studied, suggesting limitations of some of the techniques, and indicating that induced affect may be measured relatively specifically.
