From: Oscillatory activity in auditory cortex reflects the perceptual level of audio-tactile integration
Behavioral results: (A) Average magnitudes of auditory localization errors with respect to stimulation angle. (B) Average magnitude of tactile localization errors with respect to stimulation angle. (C) Systematic localization biases as a function of stimulus disparity (negative = left, positive = right). The error bars indicate the 95% confidence intervals at each disparity. (D) Comparison between the portion of the observed bias that arises from cross-modal interactions (“perceptual bias,” represented in black and estimated in trials where the modality of interest was localized first) and the portion which may arise from a possible bias towards the first response (i.e., “reference-related bias,” represented in gray and defined as the difference between trials in which the respective modality was localized second and the perceptual bias). (E) Systematic localization biases broken into trials with non-coherently (black) and coherently (gray) modulated stimulus pairs (cf. Fig. 1A). (F) Partial integration: Systematic localization biases after excluding fully integrated trials (i.e., trials in which both modalities were localized within ±6° relative to each other).
