Time experience during depression.

Before antidepressant medication was therapeutically effective, 30 severely depressed hospitalized patients (primarily unipolar) were compared with 30 controls on several aspects of time experience. In comparison to controls, depressed patients were most preoccupied with past events, focused less on present and future events, attended to more distant past events and memories, focused on more imminent future events, reported longer time spans for present story productions, and overestimated 160-second, 240-second, 15-minute, and 30-minute time intervals. Confirming the objective time estimations, depressed patients indicated on a verbal report measure that they experienced time passing slowly during the experiment, that they generally overestimate time, and that previously time did not seem to pass so slowly.

Information processing vs visual attention during incidental learning.

The relationship between attention and incidental learning during discrimination training was studied in 30 children, aged 10 to 11. A polymetric eye-movement recorder measured direct visual attention. Consistent with previous findings, recall of incidental stimuli was greatest during the initial and terminal stages of intentional learning. Contrary to previous explanations, however, visual attention to incidental stimuli was not related to training. While individual differences in attention to incidental stimuli were predictive of recall, attention to incidental stimuli was not related to level of training. Results suggested that changes in higher order information processing rather than direct visual attention were responsible for the curvilinear learning of incidental stimuli during intentional training.
