Reusable and disposable EDA/GSR electrodes both use isotonic gel but the formulas are different so results will be almost identical but will show a small difference. The researcher should compare one electrode setup to the other during a measurement with a single EDA/GSR series amplifier. Disposable electrodes offer the advantage of using new electrodes for each recording, thus avoiding the issue of cleaning reusable electrodes.
The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
View AllBIOPAC provides software and hardware that allows research teams to study stimulus presentation data. Here are a few notable studies using BIOPAC equipment for research on stimuli’s effects using ECG and SCL data. Your Face Scares Me This study addressed the impact of individual differences in social anxiety by examining the effects of perceptual load and stimulus valence when […]
