Machine classification of significant psychophysiological response

A system comprising:

• at least one hardware processor;
• and
• a non-transitory computer-readable storage medium having stored thereon program instructions, the program instructions executable by the at least one hardware processor to:
• receive, as input, physiological parameters data measured in a human subject in response to an administered test question protocol comprising (a) a plurality of test question segments, each comprising at least one test question, and (b) a recovery period following each of said test question segments,
• determine a stress signal associated with said test question protocol, based, at least in part, on one or more states of stress detected in said physiological parameters data,
• temporally associate values of said stress signal with said plurality of test question segments and said recovery periods, and
• calculate, for at least some of said test question segments, a segment psychophysiological response score associated with said responses by said subject, based on an analysis of said temporally associated values of said stress signal.
