PsPM-BAER dataset
=================

Repository Version: 2017.02.07

This dataset contains four skin conductance response (SCR) measurements of 60 s duration from each of 40 healthy male university students (18-35 years) who participated in a public speaking anticipatory anxiety paradigm with a repeated-measures factorial design.

Data Files:

The data file name is composed of: 
 - BAER_ The dataset name
 - SXX_  The subject number (eg. S01)
 - CC    one of four possible conditions: 2 baseline recordings (BL1, BL2), after announcement of speech (R1), after disclosure of topic (R2)

Data are stored as .mat files for use with MATLAB (The MathWorks Inc., Natick, USA) in a format readable by the PsPM toolbox (pspm.sourceforge.net). All matlab files are saved in MATLAB 8.6 (R2015b) format.
