Contribution à une approche écologique de la cognition : effets des nuisances physiques sur des enchaînements de traitement de l'information

Abstract : Cognitive psychology considers physical environment as being at most interference in information processing. Nevertheless, we assume that recognizing the full part of environment leads to (a) an improvement in the predictive power of cognitive models, and (b) provides a sharp methodological tool, which can reveal the cognitive processes and the physiological mechanisms regulating the world-organism relationships. This twofold hypothesis has been tested by investigating the behavioral and physiological effects of physical stressors (inadequate noise and lighting) during a simulated procee control (a complex cognitive task). In such conditions, the subjects' response times are not affected in the same way, depending on the nature of the ongoing processing (perception, diagnosis, decision...), its temporal location within the response pattern, and the type of environment. Moreover, close to these changes in performance, we observed changes in the physiological time-locked indicators (cardiac output, cerebral activation, hemispheric asymmetry...). These results allow validating use of physical factors as probes within the frame of an ecological model of information processing.
