Conclusion

 

 Remember, this research is done in a controlled laboratory situation.  The stimuli are simple, immediate on/off colored lights.  The officers’ responses are unaffected by issues of race, sex, economic status, street experience or the emotional status of the officer, etc.  The researchers were only interested in measuring reaction to very neutral situation – in essence to establish simple base rates of reaction time under a variety of circumstances.

 

 The next level of research to be conducted is to test the concepts explored in this series of experiments, in a controlled, near real situation and begin to examine the impart of higher levels of stress on perception, processing and reaction.

 

 The authors wish to thank Minnesota State University, Mankato, Tempe, Arizona Police Department for their outstanding cooperation and hospitality, especially Sgt.
