Animacy and animate imagery improve retention in the method of loci among novice users.

Recently, researchers have identified word animacy as a strong predictor of recall. In contrast, the method of loci is an ancient mnemonic technique which takes advantage of highly structured encoding and recall processes alongside a strong imagery component to create easily remembered "memory palaces." The present experiments examine the combined effectiveness of these techniques: Experiment 1 (N = 154) demonstrates that the method of loci and word animacy have additive effects, while Experiment 2 (N = 200) demonstrates that the additive effect of animacy is likely related to both the animate nature of words themselves and animate imagery associated with them.

A categorical recall strategy does not explain animacy effects in episodic memory.

Animate stimuli are better remembered than matched inanimate stimuli in free recall. Three experiments tested the hypothesis that animacy advantages are due to a more efficient use of a categorical retrieval cue. Experiment 1 developed an "embedded list" procedure that was designed to disrupt participants' ability to perceive category structure at encoding; a strong animacy effect remained.

Source-constrained retrieval and survival processing.

Three experiments investigated the mnemonic effects of source-constrained retrieval in the survival-processing paradigm. Participants were asked to make survival-based or control decisions (pleasantness or moving judgments) about items prior to a source identification test. The source test was followed by a surprise free recall test for all items processed during the experiment, including the new items (foils) presented during the source test.

Adaptive memory: animacy effects persist in paired-associate learning.

Recent evidence suggests that animate stimuli are remembered better than matched inanimate stimuli. Two experiments tested whether this animacy effect persists in paired-associate learning of foreign words. Experiment 1 randomly paired Swahili words with matched animate and inanimate English words.

Adaptive memory: the mnemonic value of animacy.

Distinguishing between living (animate) and nonliving (inanimate) things is essential for survival and successful reproduction. Animacy is widely recognized as a foundational dimension, appearing early in development, but its role in remembering is currently unknown. We report two studies suggesting that animacy is a critical mnemonic dimension and is one of the most important item dimensions ultimately controlling retention.

Adaptive memory: animacy processing produces mnemonic advantages.

It is adaptive to remember animates, particularly animate agents, because they play an important role in survival and reproduction. Yet, surprisingly, the role of animacy in mnemonic processing has received little direct attention in the literature. In two experiments, participants were presented with pronounceable nonwords and properties characteristic of either living (animate) or nonliving (inanimate) things.

Adaptive memory: fitness relevance and the hunter-gatherer mind.

Recent studies suggest that human memory systems are "tuned" to remember information that is processed in terms of its fitness value. When people are asked to rate the relevance of words to a survival scenario, performance on subsequent surprise memory tests exceeds that obtained after most other known encoding techniques. The present experiments explored this effect using survival scenarios designed to mimic the division of labor thought to characterize early hunter-gatherer societies.
