Reassessing Intertemporal Choice: Human decision-making is more optimal in a foraging task than in a self-control task

Frontiers in Psychology, 2015
Many contemporary concerns (e.g., addiction, failure to save) can be viewed as intertemporal choice problems in which the consequences of choices are realized at different times.

Evolution in Archaeology [PDF]

, 2008
This review begins with a brief outline of the key concepts of Darwinian archaeology. Its history is then summarized, beginning with its emergence as a significant theoretical focus within the discipline in the early 1980s; its main present-day currents ...

One factor to bind them all: visual foraging organization to predict patch leaving behavior with ROC curves

Cognitive Research
Predicting quitting rules is critical in visual search: Did I search enough for a cancer nodule in a breast X-ray or a threat in a baggage airport scanner? This study examines the predictive power of search organization indexes like best-r, mean ITD, PAO,

Agent‐based modeling may help to merge research traditions in foraging ecology in Europe and North America

Wildlife Society Bulletin, 2017
Although ducks have long been popular research subjects in both North America and Europe, geographical divergences in research orientation have developed during the past several decades for studying foraging ecology.

Trade‐Offs Between Forage Availability, Accessibility, and Predation Risk on Winter Foraging Strategies of Wood Bison (Bison bison athabascae)

Ecology and Evolution
Optimal foraging theory (OFT) and the energy maximization hypothesis (EMH) have long been essential when examining wildlife habitat selection. At high latitudes and altitudes, animals in winter face greater limitations in availability and accessibility ...

Combining radio-telemetry and radar measurements to test optimal foraging in an aerial insectivore bird

eLife
Optimal foraging theory posits that foragers adjust their movements based on prey abundance to optimize food intake. While extensively studied in terrestrial and marine environments, aerial foraging has remained relatively unexplored due to technological

The Influence of Predator-Prey Population Dynamics on the Long-term Evolution of Food Web Structure

, 2000
We develop a set of equations to describe the population dynamics of many interacting species in food webs. Predator-prey interactions are non-linear, and are based on ratio-dependent functional responses.

Human Swarm Interaction: An Experimental Study of Two Types of Interaction with Foraging Swarms [PDF]

, 2013
In this paper we present the first study of human-swarm interaction comparing two fundamental types of interaction, coined intermittent and environmental. These types are exemplified by two control methods, selection and beacon control, made available to

The emergence of leaders and followers in foraging pairs when the qualities of individuals differ [PDF]

, 2008
Background Foraging in groups offers animals a number of advantages, such as increasing their likelihood of finding food or detecting and avoiding predators.

Wind field and sex constrain the flight speeds of central-place foraging albatrosses [PDF]

, 2009
By extracting energy from the highly dynamic wind and wave fields that typify pelagic habitats, albatrosses are able to proceed almost exclusively by gliding flight.
