300 – Line In Audio Adapter Compatibility

The Biopac Science Lab MP40 unit connects to the computer via Line-In.
Important—Audio line in is not the same as headphones.
If a computer does not have a built-in Line-In jack, an external audio adapter can be used.
BIOPAC Systems, Inc. has reviewed five external sound adapters. All of the reviewed adapters are compatible with the MP40 unit, but their ease of use and signal quality vary. The reviewed audio adapters have the following specifications in common:

Optimize Event-Related EDA

Electrodermal Activity (EDA) is an objective index for understanding emotional states. Researchers measure EDA to gain insights on psychological or physiological response, leading them down the path of scientific discovery. Because EDA is so important to research, BIOPAC has created tools to optimize event-related EDA analysis. Topics include: how to identify skin conductance responses, convert stim events from E-Prime SuperLab, Presentation, Vizard, etc., into AcqKnowledge events that can used for analysis, and score skin conductance responses using the AcqKnowledge automated EDA analysis tool.
