Primacy and recency effects were directly compared between the groups. In the delayed recall only, the probability of no recalls was also compared. Standardized residuals were used to identify the cells which underlie the significant results (i.e., statistically significant cells are those with absolute standardized residual > 1.96, indicated in bold fonts). F, first word (word 1); M, middle list words (words 2–8); R, recent words (words 9–10); none, no word was retrieved; N, number of words within each cell; DR, delayed recall.
Bonferroni correction for multiple comparisons.
