O'Regan & Noë (O&N) argue that there is no need of internal, more or less picture-like, representation of the visual world in the brain. They propose a new approach in which vision is a mode of exploration of the world that is mediated by knowledge of sensorimotor contingencies. Data obtained in “change blindness” experiments support this assumption.

Auditory Scenes

Previous research has demonstrated surprisingly poor performance in participants who are asked to detect changes in briefly disrupted auditory scenes. So far, this change-deafness phenomenon has been found in naturalistic sound scenes and random pure-tone stacks. We now present evidence for this effect in harmonic chords, that is, in a different, yet fundamental aspect of human auditory experience. We investigated the influence of the type of disruption and its duration on change detection. Change deafness was observed regardless of whether white noise or silence had disrupted the chords and was stronger for deleted than for added tones. Crucially, the change-deafness effect was only observed for gaps exceeding 60 ms, and increased with gap durations up to 2000 ms. The present data, in line with previous studies using different stimuli, support the view that the effect is due to a masking of the change-related transient and to the decay of a time-dependent process. For the stimuli at hand, the decay of neural-adaptation-based auditory enhancement is suggested.

Auditory Change Detection

Psychophysical experiments show that auditory change detection can be disturbed in situations in which listeners have to monitor complex auditory input. We made use of this change deafness effect to segregate the neural correlates of physical change in auditory input from brain responses related to conscious change perception in an fMRI experiment. Participants listened to two successively presented complex auditory scenes, which consisted of six auditory streams, and had to decide whether scenes were identical or whether the frequency of one stream was changed between presentations. Our results show that physical changes in auditory input, independent of successful change detection, are represented at the level of auditory cortex. Activations related to conscious change perception, independent of physical change, were found in the insula and the ACC. Moreover, our data provide evidence for significant effective connectivity between auditory cortex and the insula in the case of correctly detected auditory changes, but not for missed changes. This underlines the importance of the insula/anterior cingulate network for conscious change detection.
