Abstract
-
The effect of concurrent memory tasks on prospective time estimates was investigated. In order to deter participants from using self-paced counting to scale duration, they were required to perform a word-reading task during the temporal stimulus. In each experiment, participants estimated the duration of 40- and 60-s stimuli. In Experiment 1, the presence versus absence of three concurrent memory tasks (estimating the number of words, recalling words and recognizing words) was manipulated. Time estimates were shortened by the word-reading task, compared to a no-task-control condition. Under the word-reading task, time estimates were unaffected by the presence versus absence of the memory tasks. Measures of word recall and word recognition were greater when participants were instructed to perform those tasks prior to stimulus presentation (prospectively) versus following stimulus presentation (retrospectively). Estimates of the number of words presented were lower when participants performed the tasks prospectively versus retrospectively. In Experiment 2, participants performed a word-reading task, while instruction to focus on timing or on a word-memory task was manipulated. Results showed that time estimates were longer, and more accurate, when participants were instructed to focus on timing versus word memorization. Measures of word recall and word recognition were greater when participants were instructed to focus on word memorization rather than on timing. In both experiments, time estimates were positively correlated with estimates of the number of words presented during the interval. Results suggest the mediation of time estimates by estimates of the number of words presented and interference between timing and memorizing words.
