IDENTIFYING SENSORY INPUTS AFFECTING WORKING MEMORY LOAD OF AN INDIVIDUAL

In an aspect of the invention, a method of identifying sensory inputs affecting working memory load of an individual is provided. The method comprises monitoring (S101) working memory load of the individual (20) using a sensor device (12); detecting (S102) an increase in the monitored working memory load of the individual (20); registering a sound using a microphone of noise-reducing headphones worn by the individual (20); identifying (S103), in response to detecting the increase in the monitored working memory load of the individual, the registered sound as a sensory input affecting the working memory load of the individual (20); and diminishing (S104b) an impact that the sound has on the working memory load of the individual (20) by indicating to the noise-reducing headphones that an increase in working memory load of the individual (20) has been detected, in response to which the noise-reducing headphones initiate a countermeasure by subjecting the individual (20) to an out-of-phase representation of the registered sound.
