| Abstract: | Three studies investigated both serial learning (SL) and retention processes among first through sixth graders. SL processes were evaluated for both pictorial and verbal materials by use of a probing methodology, and retention processes were studied as a function of the amount of intratask interference during original learning. All three SL stimuli considered (prior item, serial position, and prior-item cluster) were found to be functional, although the prior-item stimulus was most frequently used. Additionally, SL rate was found to improve with increasing age. The introduction of interference into SL through acoustic, associative, or semantic similarity facilitated retention in control as well as proactive and retroactive inhibition conditions. Pictorial serial list items improved SL performance only for second, third, and fourth graders, while fifth graders performed better with verbal materials and sixth-grade performance was comparable in both presentation modes. |
