Political scientist Gregg Murray, Ph.D. recently published a post on Psychology Today regarding electrophysiological cues in highly political individuals. In it, he discusses the inherent biases of those identifying with a certain political party, and underlying physical evidence quantified using electrodermal activity. Murray cites a study performed by Petersen, Giessing and Nielsen in which partisan subjects were hooked up to BIOPAC EDA equipment to measure skin conductance response. Such cues that elicited responses ranged from highly politicized topics such as gun control to simply images of the opposing party’s logo. In Murray’s article SS57LA EDA Leads for disposable EDA electrodes are shown, and BIOPAC offers these as well as various options for EDA recording, including the reusable SS3LA Finger Transducer and TSD203 Finger Transducer, as well as the BioNomadix EDA Lead for wireless recording.

Many studies use hand dynamometry to objectively quantify exerted effort during experiments most commonly related to the study of motivation.
We’ll focus on this topic and go over everything you need to know to record dynamometry data in the MRI or in the lab. Topics include
– Calibrating for maximum voluntary contraction (MVC)
– Real-time access to the dynamometer signal by third-party applications
– How researchers have used this equipment
– Creating a visual task that gives feedback on exerted effort as well as rewards to the participant

Discovering and understanding what motivates humans to produce better results has intrigued many researchers. Many researchers have explored the psychophysiological processes that drive our behavior. Here are some recent studies that have used BIOPAC systems to research motivation… Motivation and Pleasure Deficits Undermine the Benefits of Social Affiliation in Psychosis. Blanchard, J. J., Smith, J. […]
Eye tracking technology has come a long way and has enabled researchers to conduct mobile experiments and track participants in real world scenarios.
