- Psychological adaptation
A psychological adaptation, also called an
Evolved psychological mechanism or EPM, is an aspect of a human or other animal's psychology that is the result ofevolution ary pressures. It could serve a specific purpose, have served a purpose in the past (seevestigiality ), or be a side-effect of another EPM (seespandrel_(biology) ).Evolutionary psychology proposes that the human psychology mostly comprises psychological adaptations, in opposition to blank slate models of human psychology such as thestandard social science model , [http://salmon.psy.plym.ac.uk/Year1/psy150/sociobiology.htm#debate Dead link|date=June 2008] popular throughout most of thetwentieth century .Evolutionary psychologist,
David Buss , lays out six properties of evolved psychological mechanisms (EPM's):
# An EPM exists in the form that it does because it solved a specific problem of survival orreproduction recurrently over evolutionary history.
# An EPM is designed to take in only a narrow slice of information
# The input of an EPM tells an organism the particular adaptive problem it is facing
# The input of an EPM is transformed through decision rules into output
# The output of an EPM can bephysiological activity, information to other psychological mechanisms, or manifest behaviors
# The output of an EPM is directed toward the solution to a specific adaptive problemFurther important properties include the following:
* EPM's provide nonarbitrary criteria, (i.e. adaptive function) for "carving the mind at its joints," (i.e. evolved structure).
* EPM's tend to aid in solving specific adaptive problems, (e.g. food selection, mate selection, intrasexual competition, etc.)
* EPM's are believed to be numerous, which contributes to human behavioral flexibility. An analogy would be like a carpenter who, instead of having one tool that does everything, has many tools, each with a specific function for a specific task, (e.g. a hammer for pounding nails, a saw for cutting wood, etc.)
* Some EPM's are "domain-specific", (i.e. evolved to solve specific, recurrent adaptive problems), while others are "domain-general", (i.e. evolved to aid the individual in dealing with novelty in the environment).The least controversial EPMs are those commonly known as
instinct s, including interpreting stereoscopic vision and suckling a mother's breast.ee also
