This lab is configured for individual subject participation. The smallest of the three labs, audio-based experiments are often conducted in Lab B with stimuli delivered via headphones. Video stimuli can be delivered through a standard-sized computer monitor. Similar to all individual-subject labs in the ICR, stimulus presentation in Lab B can be time-locked to psychophysiological data collection. Lab B time-locking is subject to restrictions of Windows 7 command cues.
Psychophysiological variables measured in Lab B include:
• Heart Rate Activity (EKG) to index attention paid to media
• Skin Conductance Activity (EDA) to index excitement/arousal in response to media
• Facial Muscle Activity (EMG) to index emotional response to media
Lab B may be used for non-psychophysiological research as well. Media Lab and Direct RT software is installed to allow for researcher control over stimuli delivery as well as a measurement of a range of dependent variables from self-reported scales to secondary task reaction time (STRT).
