A meta-analysis examined the relation between self-esteem and ingroup bias. The project focused on effects of ingroup bias strategy and measurement of self-esteem. Results indicated that high-self-esteem individuals exhibited more ingroup bias than did low-self-esteem individuals. Bias strategy and self-esteem measurement moderated this relation. When using “direct” ingroup bias strategies, high-self-esteem individuals showed more bias than did low-self-esteem individuals. When using “indirect” strategies, groups exhibited comparable amounts of bias. Results were comparable for collective and personal self-esteem measures. Examination of specific collective measures indicated that self-esteem defined by the Collective Self-Esteem Scale (Luhtanen & Crocker, 1992) did not predict differences in ingroup bias, whereas group identification measures did predict differences in ingroup bias. Results are interpreted as indicating that both high and low-self-esteem individuals exhibit ingroup bias; however, expression of ingroup bias by individuals with low self-esteem is constrained by situational factors. Furthermore, individual-level factors such as personal self-esteem may be useful in predicting collective enhancement.

The present study examined the joint effects of repetition and response deadline on associative recognition in older adults. Young and older adults studied lists of unrelated word pairs, half presented once (weak pairs) and half presented four times (strong pairs). Test lists contained old (intact) pairs, pairs consisting of old words that had been studied with other partners (rearranged lures), and unstudied pairs (new lures), and participants were asked to respond "old" only to intact pairs. In Experiment 1, participants were tested with both short and long deadlines. In Experiment 2, the tests were unpaced. In both experiments, repetition increased hit rates for young and older adults. Young adults tested with a long deadline showed reduced (Experiment 1) or invariant (Experiment 2) false alarms to rearranged lures when word pairs were studied more often. Young adults tested with a short deadline and older adults tested under all conditions had increased false alarm rates forstrong rearranged pairs. Implications of these results for theories of associative recognition and cognitive aging are explored.

In 3 experiments, young and older adults studied lists of unrelated word pairs and were given confidence-rated item and associative recognition tests. Several different models of recognition were fit to the confidence-rating data using techniques described by S. Macho (2002, 2004). Concordant with previous findings, item recognition data were best fit by an unequal-variance signal detection theory model for both young and older adults. For both age groups, associative recognition performance was best explained by models incorporating both recollection and familiarity components. Examination of parameter estimates supported the conclusion that recollection is reduced in old age, but inferences about age differences in familiarity were highly model dependent. Implications for dual-process models of memory in old age are discussed.
