| Abstract: | In 2 experiments, 48 19–35 yr olds and 48 59–75 yr olds were engaged in semantic and nonsemantic orienting tasks and were subsequently given incidental or expected recall and recognition tasks. Reaction time (RT) patterns from the orienting tasks suggested that all Ss experienced similar semantic activation during encoding. Under incidental conditions, age differences in memory performance were minimal. When memory tests were expected, younger Ss recalled and recognized more items than did older Ss, suggesting that younger Ss were more effective in their deployment of mnemonic strategies. The age difference was particularly pronounced for unattended items, which suggests an age difference in the capacity to encode all of the episodic information.
