Do healthy elders, like young adults, remember animates better than inanimates? An adaptive view

Abstract : Background/Study Context: It has been found that young adults remember animates better than inanimates. According to the adaptive view of human memory, this is due to the fact that animates are more important for fitness purposes than inanimates. This effect has been ascribed to episodic memory, where older people exhibit difficulties. Methods: Here the authors investigated whether the animacy effect in memory also occurs for healthy older adults. Older and young adults categorized words for their animacy characteristics and were then given an unexpected recognition test on the words using the Remember/Know paradigm. Executive functions were also evaluated using several measures. Results: For both overall Recognition and Remember responses, a reliable animacy effect on hit rates was found in young but not in older adults. Controlling for certain executive functions led to reliable and comparable animacy effects in both groups. There was no reliable effect of animacy on Know responses. Conclusion: Thus, unlike young adults, older adults do not remember animates better than inanimates; this pattern can be attributable to a decline in executive functions.
