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.

Motivated to retrieve: how often are you willing to go back to the well when the well is dry?
TL;DR: A strong negative correlation was found between individual differences in motivation and participants' exit latencies, and was present only when the retrieval task started out as relatively difficult.

Different habitats, different habits? Response to foraging information in the parasitic wasp Venturia canescens
Andra Thiel,Andra Thiel,Andra Thiel,Gerard Driessen,Gerard Driessen,Thomas S. Hoffmeister,Thomas S. Hoffmeister +6 more
TL;DR: The behavior of the arrhenotokous females should result in a spreading of offspring across the habitat and, thus, reduced sib-mating, and the foraging strategy of these wasps might be an adaptation to reduce costs associated with inbreeding.

On the lawfulness of the decision to terminate memory search.
TL;DR: A modified free-recall paradigm was used to examine the decision to terminate search and revealed that the total time engaged in retrieval was a monotonically increasing function of the total number of items retrieved, whereas the time from final retrieval to search termination (exit latency) was a non-monotonically decreasing function.

Cognitive Aging and Adaptive Foraging Behavior
TL;DR: It is suggested that both younger and older adults are adaptive in the sense of adjusting the parameters of their foraging strategy as a function of task characteristics, Nevertheless, older adults show overall poorer performance compared with younger adults even when instructed to use an optimal strategy.

Humans and insects decide in similar ways.
TL;DR: It is shown for the first time ever that human subjects use a motivational mechanism similar to small insects such as parasitoids and bumblebees to decide when to leave a patch and the plausibility of a neural basis for the motivation mechanism highlighted here is discussed, bridging the gap between behavioral ecology and neuroeconomy.
