Evidence for mixed feelings of happiness and sadness from brief moments in time.

Theorists disagree about whether valence is a basic building block of affective experience or whether the positive and negative substrates underlying valence are separable in experience. If positivity and negativity are separable in experience, people should be able to feel happy and sad at the same time. We addressed limitations of earlier evidence for mixed feelings by collecting moment-to-moment measures of happiness and sadness that required participants to monitor their feelings only occasionally. In Study 1, participants were occasionally cued to press one button if they felt happy and another if they felt sad. Participants spent more time reporting mixed feelings (i.e., simultaneously pressing both buttons) during bittersweet scenes than non-bittersweet scenes. In Study 2, participants reported their feelings only once. Participants spent more time reporting mixed feelings when cued during a bittersweet, as opposed to non-bittersweet, scene. These results extend earlier evidence that happiness and sadness can co-occur.
