EDA SCR Event Related Analysis tutorial and primer available

AcqKnowledge software for  MP160, MP150, and MP36R research systems includes a fully-automated electrodermal activity (EDA) data scoring routine. The feature includes options for deriving phasic EDA from tonic EDA, locating skin conductance responses (SCR), and event-related EDA analysis.

A Guide for Analysing Electrodermal Activity (EDA) & Skin Conductance Responses (SCRs) for Psychological Experiments (Dr Jason J Braithwaite, Dr Derrick G Watson, Robert Jones, Mickey Rowe; compiled 2013).

BIOPAC’s event-related EDA analysis works in conjunction with a Digital input to stim events feature. The Digital input to stim events function works with TTL trigger information coming from applications such as Superlab®, E-Prime®, DirectRT®, MediaLab®, Inquisit®, and Presentation®. It converts TTL data acquired on the digital channels of an MP device into stimulus events. Stimulus delivery events are defined in the graph for each low to high transition of the digital data, the indications of stimulus delivery. The digital channels are interpreted as a binary number. Each stimulus event placed into the graph has the corresponding number included with its label. The event-related EDA tool locates the stimulus events and looks for an SCR that falls within a time window after the stimulus was presented to the subject.

The following measures are extracted from the electrodermal activity data:
