Figure 4.
Medians (filled circles) and interquartile ranges (error bars) for the measured stimulus onset asynchrony (SOA) obtained from young and older adults on the visual two-item (bottom) and four-item (top) temporal-order identification tasks [data from Humes et al. (2013)]. Results are shown relative to the temporal parameters of the stimulus sequence with the white rectangle indicating the initial stimulus in the sequence for both subject groups and tasks and the grey rectangles representing the location of the subsequent stimuli in the sequence based on the median SOAs measured for each task and group.
