Foraging across the life span: is there a reduction in exploration with aging?
TLDR
Overall, the evidence suggests that foraging behavior may undergo significant changes across the life span across internal and external search, and finds evidence of a trend toward reduced exploration with increased age.Abstract:
Does foraging change across the life span, and in particular, with aging? We report data from two foraging tasks used to investigate age differences in search in external environments as well as internal search in memory. Overall, the evidence suggests that foraging behavior may undergo significant changes across the life span across internal and external search. In particular, we find evidence of a trend towards reduced exploration with increased age. We discuss these findings in light of theories that postulate a link between aging and reductions in novelty seeking and exploratory behavior.read more

TL;DR: In this article, the authors explore how potential tradeoffs depend on the conceptualization of exploration and exploitation, the influencing environmental, social, and individual factors, the scale at which exploration and exploit are considered, the relationship and types of transitions between the two behaviors, and the goals of the decision maker.

The Affective Neuroscience of Aging.
TL;DR: This review examines how age-related brain changes influence processes such as attending to and remembering emotional stimuli, regulating emotion, and recognizing emotional expressions, as well as empathy, risk taking, impulsivity, behavior change, and attentional focus.

Learning about aposematic prey
TL;DR: The aim of the review is to promote the view that predators do not simply learn to avoid aposematic prey, but rather make adaptive decisions about both when to gather information about defended prey and when to include them in their diets.

A Primer on Foraging and the Explore/Exploit Trade-Off for Psychiatry Research
TL;DR: The explore/exploit trade-off has been studied extensively in behavioral ecology and computational neuroscience, but is relatively new to the field of psychiatry as discussed by the authors, which can offer psychiatry research a new approach to studying motivation, outcome valuation, and effort-related processes which are disrupted in many mental and emotional disorders.

TL;DR: A fresh understanding of the neurochemical influences on PFC function has led to new treatments for cognitive disorders such as Attention Deficit Hyperactivity Disorder (ADHD), and may help to elucidate the prevalence of PFC dysfunction in other mental disorders.

Neural mechanisms of foraging.
TL;DR: This article showed that humans can alternate between two modes of choice, comparative decision-making and foraging, depending on distinct neural mechanisms in ventromedial prefrontal cortex (vmPFC) and anterior cingulate cortex (ACC) using distinct reference frames.

TL;DR: Longitudinal data from a national sample of Germans showed that differential stability was relatively strong among all age groups but that it increased among young adults, peaked in later life, and then declined among the oldest old.
