How we feel affects what we see

“Thus, positive moods enhanced peripheral vision and increased the extent to which the brain encoded information in those parts of the visual field, to which the participants did not pay attention. Conversely, negative moods decreased the encoding of peripheral information. But does the enhanced peripheral vision that occurs because of positive mood induction come at the expense of central (or “foveal”) vision? Schmitz and his colleagues compared FFA activity in the positive and negative mood induction trials, but found no difference. The enhanced peripheral vision following positive mood induction does not, therefore, occur as a result of a trade-off with central vision.”
