The varieties of foraging experience.

In psychology, it’s not yet standard practice to think carefully about how the shape of our cognition is tied to problems in ancestral environments, because the past is widely seen as unknowable. However, there are many information-processing problems that are well formed and widespread enough to consider as possible domains of psychological adaptation. One such domain is foraging, or search. Research reported in this special issue reveals several interesting features of our psychology of search, including that mate search behavior reveals an exploration-exploitation trade-off that may be common across foraging tasks; that individuals possess distinct degrees of exploration-proneness across different types of search tasks; and that natural environments exhibit a high degree of patchiness, consistent with the proposal that humans intuitively assume that resources come in clumps. Together, these papers suggest that the psychology of foraging is more pervasive in our daily lives than we might realize, and that its architecture may be more complex than we think.
