Lab B Banner

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).
