An independent samples t-test showed no difference in span
between the odd-numbered and even-numbered lists
(Odd-numbers M = 5.09, CI = 4.77–5.40; Even-numbers M = 5.12,
CI = 4.69–5.55; t(66) = .11, p = .911, Cohen’s d = .03). Subsequent
analyses therefore combine the two list types.
Recall of isolated digits, isolated words, digit pairs and word
pairs was analysed for the final four lists that participants were
presented. For
the sake of simplicity and consistency, we only analysed sequences
in terms of pairs of successive items , rather than investigating longer
sequences, the opportunity for occurrence of which would vary
as a function of span length. Table 5 shows the proportion of isolated
digits, isolated words, digit pairs, and word pairs that were
correctly recalled by participants. A 2 (sequence-type: isolated or
paired) 2 (stimulus-type: digits or words) repeated measures.
