In today�s technologically driven world, there is a need to better understand the ways that common computer malfunctions affect\ncomputer users. These malfunctions may have measurable influences on computer user�s cognitive, emotional, and behavioral\nresponses. An experiment was conducted where participants conducted a series of web search tasks while wearing functional nearinfrared\nspectroscopy (fNIRS) and galvanic skin response sensors. Two computer malfunctionswere introduced during the sessions\nwhich had the potential to influence correlates of user trust and suspicion. Surveys were given after each session to measure user�s\nperceived emotional state, cognitive load, and perceived trust. Results suggest that fNIRS can be used to measure the different\ncognitive and emotional responses associated with computer malfunctions. These cognitive and emotional changes were correlated\nwith users� self-report levels of suspicion and trust, and they in turn suggest future work that further explores the capability of\nfNIRS for the measurement of user experience during human-computer interactions.
