Point process temporal structure characterizes electrodermal activity

An Electrodermal Activity Psychophysiologic Model

To study the changes on the electrical characteristics of the skin several problems have to be solved. We present a model for the electrodermal activity (EDA) that provides the means to detect and quantify four event types: a discrete event; a pair of events overlapping in the increasing zone; a pair of events overlapping in a decreasing zone; and an isolated small event. The presented EDA mode...

Reduced electrodermal activity in psychopathy-prone adolescents.

This study tests the hypothesis that psychopathy-prone adolescents show reduced anticipatory skin conductance responding. Electrodermal activity was recorded while participants anticipated and responded to a 105 dB signaled or unsignaled white-noise burst. Using an extreme groups design, the authors used Child Psychopathy Scale (D. R. Lynam, 1997) scores from a community sample of 335 male adol...

Asymmetry of electrodermal activity in man

Skin conductance responses were examined bilaterally in a group of 12 normal subjects. Ten of them were right-handed and two were left-handed. All right-handed subjects exhibited asymmetry in skin conductance response during verbal-numerical and visual-imagery tasks. With the visual activity, larger responses were found in the left hand; while during the verbal task. larger responses were recor...

An Automated System for Processing Electrodermal Activity

A new approach is presented in this paper for the display and processing of electrodermal activity. It offers a fully automated interface for the pre-processing and scoring individual skin conductance responses (SCRs). The application supports parallel processing by means of multiple threads. Batch processing is also available. The XML format is used to describe the derived features. The system...
