Baseline Differences, Attention, and Age Differences in Timesharing Performance.
Birch, Leann Lipps
This study was designed to investigate whether age differences in timesharing performance would be found if the baseline performance of younger and older children was experimentally equated. Two groups of twelve 8-year-olds and one group of twelve 13-year-olds participated. Each subject performed a compensatory tracking task and an auditory matching task, first alone and then timeshared. The 8- and 13-year-old baseline groups performed baseline trials on each task prior to timesharing trials. Each 8-year-old in the training group was randomly paired with a 13-year-old and given sufficient single task practice before timesharing to equate the 8- and 13-year-old pair members' baselines on both tasks. Results showed trained 8-year-olds to be indistinguishable from 13-year-olds in timesharing, whereas the 8-year-old baseline group showed significantly greater decrements in timesharing and higher baseline scores on both tasks. These data provide support for the hypothesis that timeshared performance is directly related to level of baseline performance and indicate that once baseline differences are experimentally equated, no age differences in performance remain to be attributed to developmental differences in attentional processes.
