The current study used archival data to examine the effects of high and low temporal interference on memory for sequences of visuospatial stimuli in healthy young (YA), middle-aged (MA), and older adults (OA). Participants completed a computerized temporal memory task, which consisted of a sample phase and choice phase. During the sample phase, participants were instructed to remember the order in which a circle appeared on the end of each of the arms on an 8-arm radial maze. During the choice phase, two circles were presented on separate arms and participants were asked to indicate which circle appeared earliest in the previous sequence. The choice phase circles were separated by one of four temporal separations lags (0, 2, 4, and 6). Zero and 2 lag trials were averaged to constitute the high interference condition, and 4 and 6 lag trials were averaged to constitute the low interference condition. It was hypothesized that there would be more interference between temporally proximal circles in the high interference condition than temporally distant circles in the low interference condition.
