  1. Evolving the Psychological Mechanisms for Cooperation.Jeffrey R. Stevens & Marc D. Hauser - 2005 - Annual Review of Ecology, Evolution, and Systematics 36:499-518.
    Cooperation is common across nonhuman animal taxa, from the hunting of large game in lions to the harvesting of building materials in ants. Theorists have proposed a number of models to explain the evolution of cooperative behavior. These ultimate explanations, however, rarely consider the proximate constraints on the implementation of cooperative behavior. Here we review several types of cooperation and propose a suite of cognitive abilities required for each type to evolve. We propose that several types of cooperation, though theoretically (...)

    A statistical taxonomy and another “chance” for natural frequencies.Adrien Barton, Shabnam Mousavi & Jeffrey R. Stevens - 2007 - Behavioral and Brain Sciences 30 (3):255-256.
    The conclusions of Barbey & Sloman (B&S) crucially depend on evidence for different representations of statistical information. Unfortunately, a muddled distinction made among these representations calls into question the authors' conclusions. We clarify some notions of statistical representations which are often confused in the literature. These clarifications, combined with new empirical evidence, do not support a dual-process model of judgment.

    Cognitive constraints on reciprocity and tolerated scrounging.Jeffrey R. Stevens & Fiery A. Cushman - 2004 - Behavioral and Brain Sciences 27 (4):569-570.
    Each of the food-sharing models that Gurven considers demands unique cognitive capacities. Reciprocal altruism, in particular, requires a suite of complex abilities not required by alternatives such as tolerated scrounging. Integrating cognitive constraints with comparative data from other species can illuminate the adaptive benefits of food sharing in humans.

    Individual Decision Making and the Evolutionary Roots of Institutions.Robert Boyd, Gerd Gigerenzer, Peter J. Richerson, Arthur Robson, Jeffrey R. Stevens & Peter Hammerstein - unknown
    Humans hunt and kill many different species of animals, but whales are our biggest prey. In the North Atlantic, a male long-fi nned pilot whale (Globiceph- ala melaena), a large relative of the dolphins, can grow as large as 6.5 meters and weigh as much as 2.5 tons. As whales go, these are not particularly large, but there are more than 750,000 pilot whales in the North Atlantic, traveling in groups, “pods,” that range from just a few individuals to a (...)

    The dynamics of development: Challenges for bayesian rationality.Nils Straubinger, Edward T. Cokely & Jeffrey R. Stevens - 2009 - Behavioral and Brain Sciences 32 (1):103-104.
    Oaksford & Chater (O&C) focus on patterns of typical adult reasoning from a probabilistic perspective. We discuss implications of extending the probabilistic approach to lifespan development, considering the role of working memory, strategy use, and expertise. Explaining variations in human reasoning poses a challenge to Bayesian rational analysis, as it requires integrating knowledge about cognitive processes.
