Information foraging is a theory that applies the ideas from optimal foraging theory to understand how human users search for information. The theory is based on the assumption that, when searching for information, humans use "built-in" foraging mechanisms that evolved to help our animal ancestors find food.
Foraging strategy must provide the most benefit for the lowest cost – it is a balance between nutritional value and energy required. The currency of optimal foraging theory is energy because it is an essential component for organisms, but it is also the downfall of optimal foraging theory in regard to archaeology. [26]
Behavioral ecologists first tackled this topic in the 1960s and 1970s. Their goal was to quantify and formalize a set of models to test their null hypothesis that animals forage randomly. Important contributions to foraging theory have been made by:
In the mid-1970s, Glynn Isaac touched off a debate by proposing that human ancestors of this period had a "place of origin" and that they foraged outward from this home base, returning with high-quality food to share and to be processed. Over the course of the last 30 years, a variety of competing theories about how foraging occurred have been ...
This theory was modified in the 1970s by John Ostrom to describe the use of wings as an insect-foraging mechanism which then evolved into a wing stroke. [9] Research was conducted by comparing the amount of energy expended by each hunting method with the amount of food gathered.
With the return of inflation, insane gas prices, and Peter Brady, it's started to look like the 1970's revival is almost complete.However, as any cultural historian will attest, no reiteration of ...
The Stanford marshmallow experiment was a study on delayed gratification in 1970 led by psychologist Walter Mischel, a professor at Stanford University. [1] In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time.
From the 1970s onward, the dominant paleontological perspective of gendered roles in hunter-gatherer societies was of a model termed "Man the Hunter, Woman the Gatherer"; coined by anthropologists Richard Borshay Lee and Irven DeVore in 1968, it argued, based on evidence now thought to be incomplete, that contemporary foragers displayed a clear division of labour between women and men.
