Discussion
My contention is that intralist and extralist intrusion errors are ambiguous indices
of loss of location information and loss of item information, respectively. For this reason
the two types of errors were not used in deriving the experimental predictions of this
study. Nonetheless, it is necessary to ensure that the experiments in this study are
comparable to Mewhort et al.'s (1981) experiments in terms of these errors. For this
reason, intralist and extralist intrusion errors have been reported for comparison purposes.
As has been shown, when scored in terms of intralist and extralist intrusions, results from
the no-masking and the masking conditions of this experiment are comparable to those
obtained under Mewhort et al.'s (1981) Conditions 1 and 2, respectively.
The proportion of trials in which both item identity and its location were correctly
recalled was treated as a measure of partial-report performance. In terms of the new index
