Physiological Effects of Delayed System Response Time on Skin Conductance

摘要

Research on psychological effects of delayed system response time (SRT) has not lost its topicality, since uncertainty in providing immediate system response remains, even after decades of stunning enhancements in computer science. When delays occur, the user's expectancy about the temporal course of an interaction is not fulfilled which he may interpret as irritating. The current study investigates physiological effects on the skin conductance (SC) and its particular patterns in two experimental scenarios. In the first scenario, unexpected delays of 0.5, 1, and 2 seconds occur while the subject is performing a two-choice auditory categorization task, expecting the system to respond immediately after their input. The second scenario is a wizard-of-oz (woz) scenario in which the user plays the game 'concentration' that is being manipulated in order to induce various emotional states. During the 'negative' sequences delays of 6 seconds are triggered. The patterns of the mean SC curves during delays are analyzed.
