摘要：Researchers studying selective attention in depressed and dysphoric individuals have documented biases in the allocation of attention to emotional information (GotlibandJoormann, 2010; Yiend, 2010). Recent studies using eye gaze tracking have shown that when images are presented for extended durations (5–30 seconds), depressed and dysphoric individuals attend to depression-related images more than never depressed individuals and attend to positive images less (ArmstrongandOlatunji, 2012). The present study used eye gaze tracking and time course analyses to look for differences between dysphoric and non-dysphoric individuals in their attention to emotional images over time. Participants viewed sets of four images (a depression-related image, a threat-related image, a positive image, and a neutral image) while their eye fixations were tracked and recorded throughout a 10-second presentation. The time course analyses, which divided each 10-second presentation into 2-second intervals, revealed that group differences in attention to positive and depression-related images emerged only after 4 seconds had elapsed and then persisted for the remainder of the 10-second presentation. Dysphoric and non-dysphoric participants were further distinguished by the temporal profiles of their attention to positive and depression-related images. The implications for researchers' understanding of attention to emotion in dysphoria and depression are discussed.
