This article discusses issues involved with the computer simulation of expe
rimental tasks and settings used in ream research with human participants.
First, the purpose and components of simulation methodology are discussed a
long with the notion of simulation validity. Second, the common "external v
alidity" criticism often leveled at experiments is considered with particul
ar attention given to the fidelity and realism questions researchers face w
hen choosing or developing simulated team-performance environments. Third,
the advantages and disadvantages of the current state of computerized team
simulations are examined. The article concludes,with considerations for fut
ure team research using computer simulation methodology.
