In primate groups, collective movements are typically described as processes dependent on
leadership mechanisms. However, in some species, decision-making includes negotiations …

A 'consensus decision'is when the members of a group choose, collectively, between
mutually exclusive actions. In humans, consensus decisions are often made democratically …

Balancing habitual and deliberate forms of choice entails a comparison of their respective
merits—the former being faster but inflexible, and the latter slower but more versatile. Here …

This paper shows that the various computations underlying spatial cognition can be
implemented using statistical inference in a single probabilistic model. Inference is …

In a remote stream in Alaska, a rainbow trout spies a colorful dimple on the undersurface of
the water with an insect resting atop it. Darting over with mouth agape, the fish bites down …

Studying animal behavior as collective phenomena is a powerful tool for understanding
social processes, including group coordination and decision-making. However, linking …

It is uncontroversial that land animals have more elaborated cognitive abilities than their
aquatic counterparts such as fish. Yet there is no apparent a-priori reason for this. A key …

Abstract The “Monty Hall Dilemma”(MHD) is a well known probability puzzle in which a
player tries to guess which of three doors conceals a desirable prize. After an initial choice is …

We analyze a continuous-time model of a multi-agent system motivated by simulation
studies on dynamics of decision making in animal groups in motion. Each individual moves …

Explore-exploit decisions require us to trade off the benefits of exploring unknown options to
learn more about them, with exploiting known options, for immediate reward. Such decisions …
