Moderators of curiosity and information seeking in younger and older adults.

The present study examined age differences in the influence of informational value cues on curiosity and information seeking. In two experiments, younger and older adults (total = 514) rated their curiosity about content before having the opportunity to seek out more information. Experiment 1 examined the impact of social value on curiosity and information seeking about trivia.

Consequences of curiosity for recognition memory in younger and older adults.

Older adults are more prone to false recognition than younger adults, particularly when new information is semantically related to old information. Curiosity, which guides information-seeking behavior and has beneficial effects on memory across the life span, may offer protection against false recognition, but this hypothesis has not been tested experimentally to date. The current study investigated the effect of curiosity on correct and false recognition in younger and older adults (total N = 102) using a trivia paradigm.

Age Differences in Motivated Cognition: A Meta-Analysis.

Objectives: The goal of this preregistered study was to synthesize empirical findings on age differences in motivated cognition using a meta-analytic approach, with a focus on the domains of cognitive control and episodic memory.

Methods: A systematic search of articles published before July 2022 yielded 27 studies of cognitive control (N = 1,908) and 73 studies of memory (N = 5,837). Studies had to include healthy younger and older adults, a within-subjects or between-subjects comparison of motivation (high vs low), and a measure of cognitive control or memory.

The interaction of curiosity and reward on long-term memory in younger and older adults.

Long-term memory is sensitive to both intrinsic and extrinsic motivation, but little is known about the relative influence of these two sources of motivation on memory performance across the adult life span. The study examined the effects of extrinsic motivation, manipulated via monetary reward, and curiosity, a form of intrinsic motivation, on long-term memory in healthy younger and older adults. During the incidental encoding phase on Day 1, 60 younger and 53 older participants viewed high- and low-curiosity trivia items as well as unrelated face stimuli.

Aging and altruism: A meta-analysis.

Life span theories postulate that altruistic tendencies increase in adult development, but the mechanisms and moderators of age-related differences in altruism are poorly understood. In particular, it is unclear to what extent age differences in altruism reflect age differences in altruistic motivation, in resources such as education and income, or in socially desirable responding. This meta-analysis combined 16 studies assessing altruism in younger and older adults (N = 1,581).

Reward anticipation selectively boosts encoding of gist for visual objects.

Reward anticipation at encoding enhances later recognition, but it is unknown to what extent different levels of processing at encoding (gist vs. detail) can benefit from reward-related memory enhancement. In the current study, participants (N = 50) performed an incidental encoding task in which they made gist-related or detail-related judgments about pairs of visual objects while in anticipation of high or low reward.

The effect of motivational incentives on face-name hyper-binding in older adults.

Hyper-binding refers to the spontaneous formation of target-distractor associations in older adults, with consequences for subsequent memory. While hyper-binding reflects a loss of attentional and mnemonic selectivity in aging, a growing literature suggests that motivational states modulate cognitive performance in both younger and older adults. In the current study, healthy younger and older adults (N = 48 in both age groups) completed a face-name hyper-binding task with or without motivational incentives during incidental encoding.

Cognitive and motivational selectivity in healthy aging.

Normal aging is associated with a reduction in the selectivity of cognitive processes such as attention and memory. This loss of selectivity is attributed to diminished inhibition and cognitive control mechanisms in older adults, which render them more susceptible to distraction and more likely to attend to and encode irrelevant information. However, motivational selectivity appears largely preserved in aging.
