Skin Conductance Response (SCR) Analysis
AcqKnowledge includes a fully automated skin conductance response (SCR) scoring system. The software will transform skin conductance level (SCL) data to provide a skin conductance response signal and locate the responses and mark them accordingly. Once the responses have been identified and marked they are analyzed. The software pastes the results into a Journal file or Excel. The analysis can also be combined with the event related analysis tool to determine the number of responses, amplitude of the response and the timing of responses. For studies requiring the examination of spontaneously occurring skin conductance responses, such as social paradigms, cognitive tasks, and arousal studies, use the Locate SCR routine in AcqKnowledge to locate and score spontaneously occurring responses. Locate SCRs analysis will identify skin conductance responses and visually score the waveform. All SCR events are marked on the tonic waveform. In the SCR location mode the software marks the event onset, SCR point of max response, and waveform end. Responses can also be manually adjusted using the event marking tools.
