Evolutionary origins of stigmatization: the functions of social exclusion.
TLDR
The authors propose that phenomena currently placed under the general rubric of stigma involve a set of distinct psychological systems designed by natural selection to solve specific problems associated with sociality.

An opportunity cost model of subjective effort and task performance.
TLDR
It is argued that the phenomenology of effort can be understood as the felt output of these cost/benefit computations of the costs and benefits associated with task performance and motivates reduced deployment of these computational mechanisms in the service of the present task.

Modularity in cognition: framing the debate.
TLDR
It is proposed that modularity, cleanly defined, provides a useful framework for directing research and resolving debates about individual cognitive systems and the nature of human evolved cognition.

Disgust: evolved function and structure.
TLDR
It is suggested that in addition to motivating pathogen avoidance, disgust evolved to regulate decisions in the domains of mate choice and morality and is recast into a framework that can generate new lines of empirical and theoretical inquiry.

Can race be erased? Coalitional computation and social categorization
TLDR
It is shown that subjects encode coalitional affiliations as a normal part of person representation, and when cues of coalitional affiliation no longer track or correspond to race, subjects markedly reduce the extent to which they categorize others by race, and indeed may cease doing so entirely.

TLDR
From the standpoint of evolved function, glucose might better be thought of as an input to decision making systems rather than as a constraint on performance.

Revisiting Kindness and Confusion in Public Goods Experiments
There has been substantial recent interest in determining why there is cooperation in public goods experiments even in environments that provide all subjects with the incentive to free ride (see…

Cognitive systems for revenge and forgiveness.
TLDR
A subsidiary computational system designed to restore particular relationships after cost-imposing interactions by inhibiting revenge and motivating behaviors that signal benevolence for the harmdoer is posited.

Experiments investigating cooperative types in humans: a complement to evolutionary theory and simulations.
TLDR
The results support the view that the human subject population is in a stable, polymorphic equilibrium of types, and find that the subjects fall into three types, an individual's type is stable, and a group's cooperative outcomes can be remarkably well predicted if one knows its type composition.
