Psychophysiological analysis (PSPHA): a modular script-based program for analyzing psychophysiological data.

In psychophysiological research, complex tailor-made and interactive analyses of biosignals (e.g., skin conductance, heart rate, and respiration) are often required. Moreover, a synchronization between experimental stimuli and psychophysiolgical responses is necessary. In this article, we present Psychophysiological Analysis (PSPHA), a modular script-based program for analyzing biosignals in the time domain. The modules can be integrated in a VBScript, and a wizard allows easy adaption of parameters. PSPHA is a free, interactive, and flexible program for analyzing the data of psychophysiological experiments.
