Revisiting distinctive processes in memory.

In three experiments,we examined the relationship between orthographic andphonological distinctiveness and incidental recall. In each experiment, participants were given a surprise free recalltest after they read words aloud as quickly and accurately as possible. The pattern of results replicated those reported in Cortese, Watson, Wang, and Fugett (2004) for intentional and explicit free recall and recognition memory tasks in which items were read silently. Specifically, we found that phonological-to-orthographic neighborhood size influenced recall performance,whereas orthographic-to-phonologicalconsistency and phonological-to-orthographic consistency did not Also, we failed to replicate the orthographic-to-phonological consistency effect reported by Hirshman and Jackson (1997), and argue that their results were due to a confounding of consistency with phonological neighborhood size. Our results suggest that the processing of words sharing both orthography and phonology with a large number of words produces interference that reduces one's ability to remember them.

Individual differences in working memory capacity predict visual attention allocation.

To the extent that individual differences in working memory capacity (WMC) reflect differences in attention (Baddeley, 1993; Engle, Kane, & Tuholski, 1999), differences in WMC should predict performance on visual attention tasks. Individuals who scored in the upper and lower quartiles on the OSPAN working memory test performed a modification of Egly and Homa's (1984) selective attention task. In this task, the participants identified a central letter and localized a displaced letter flashed somewhere on one of three concentric rings. When the displaced letter occurred closer to fixation than the cue implied, high-WMC, but not low-WMC, individuals showed a cost in the letter localization task. This suggests that low-WMC participants allocated attention as a spotlight, whereas those with high WMC showed flexible allocation.
