Evidence for Decay in Verbal Short-Term Memory: A Commentary on Berman, Jonides, and Lewis (2009)
Campoy, Guillermo
Journal of Experimental Psychology: Learning, Memory, and Cognition, v38 n4 p1129-1136 Jul 2012
M. G. Berman, J. Jonides, and R. L. Lewis (2009) adapted the recent-probes task to investigate the causes of forgetting in short-term memory. In 7 experiments, they studied the persistence of memory traces by assessing the level of proactive interference generated by previous-trial items over a range of intertrial intervals. None of the experiments found a reduction in proactive interference over time, which they interpreted as evidence against time-based decay. However, it is possible that decay actually occurred over a shorter time period than was tested in this study, wherein the shortest decay interval was 3,300 ms. By reducing the time scale, the 2 experiments reported in the current commentary revealed a sharp decrease in proactive interference over time, with this reduction reaching a plateau in less than 3 s. This pattern suggests that decay operates in the early stages, whereas subsequent forgetting is likely to be due to interference. (Contains 2 tables, 2 figures and 4 footnotes.)
