Psychophysiological assessment tools for evaluation of learning technologies

Research on the psychophysiological assessment of the impact of information technologies on humans is reviewed, with a particular focus on learning technologies and research carried out in in the Laboratory for Information Technology Evaluation (LITE) at Missouri S&T. Measures of arousal and valence are discussed first, including galvanic skin response (GSR), pupil dilation, and heart rate. This is followed by a discussion of the measurement of eye movement using eye tracking technologies. Lastly, a summary of the LITE lab research is provided. It is concluded that the measures are promising, based on these initial LITE lab results, though further work is needed to more accurately determine the appropriate constructs and contexts for optimizing the use of these tools.
