In most domains where behavior is considered, including the study of social play, the prevailing explanatory theories rest on the assumptions that: (1) behavior is the result of \u201cprograms\u201d that can be strictly or loosely specified, located somewhere in the central nervous system, and (2) the behavior an organism produces in a certain circumstance is the result of a choice between all (or many) of the available options, assumed to be arrived at by considering internally generated predictions about the consequences of actions. To test these assumptions, we used sets of parameters generated by our previous work with rats and crickets to create an agent-based model of a game of \u201ckeep-away.\u201d We demonstrate that the agents need to possess neither behavioral programs (e.g., fixed or modal action patterns), nor any predictive capacity, in order to reproduce the tactics commonly used when organisms protect an object of interest from conspecifics. The results are presented in terms of the evolution of social play, which can be seen as a variation of the game of keep away.<\/jats:p>","DOI":"10.1177\/1059712315607606","type":"journal-article","created":{"date-parts":[[2015,10,1]],"date-time":"2015-10-01T21:24:04Z","timestamp":1443734644000},"page":"371-380","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Evolving the tactics of play fighting: insights from simulating the \u201ckeep away game\u201d in rats"],"prefix":"10.1177","volume":"23","author":[{"given":"Heather C","family":"Bell","sequence":"first","affiliation":[{"name":"Division of Biological Sciences, Section of Ecology, Behavior, and Evolution, University of California at San Diego, San Diego, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Greg D","family":"Bell","sequence":"additional","affiliation":[{"name":"Statistics Canada, Ottawa, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey A","family":"Schank","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of California at Davis, Davis, California, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio M","family":"Pellis","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, The University of Lethbridge, Lethbridge, Alberta, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,10,1]]},"reference":[{"key":"bibr1-1059712315607606","volume-title":"Play fighting","author":"Aldis O.","year":"1975"},{"key":"bibr2-1059712315607606","doi-asserted-by":"publisher","DOI":"10.2307\/j.ctt7rvqf"},{"key":"bibr3-1059712315607606","first-page":"196","volume":"27","author":"Bell H.
