EDA SCR Analysis Guide for Psychological Experiments updated

Electrodermal Activity (EDA) is an increasingly important variable in psychological science. Refinements in analysis techniques and methods of handling EDA data and making it fit for final analysis and interpretation follow ongoing improvements in technology, methodology, and reporting. Such advancements also leave room for some controversies over how EDA should be analyzed in given circumstances.

This document is designed primarily for use by non-experts in research on EDA. It provides a digestible guide of how to go from EDA data acquisition to meaningful EDA results in a few basic steps with BIOPAC Research Systems and AcqKnowledge software:
