Influence of eye position on perceived straight-ahead (PSA). A: sound localization accuracy and PSA estimates in Az for a representative subject. The changes in auditory localization accuracy (green trace) and position of gaze-fixed PSA (red trace) are modeled as above to obtain time constants (τ) and shift magnitudes (a). Resp. Error, response error. B: average change in auditory localization accuracy and PSA in response to 40° gaze shifts in Az (pooled for L and R), calculated as end-epoch averages (Δ accuracy) and model estimates (a). Average change of gaze-fixed PSA surpasses that of auditory (P < 0.05). Gaze-guided assessment of PSA remained deviated in the direction of previously sustained eye position, albeit at a decreased magnitude compared with that of the gaze-fixed condition (P < 0.05). Values prove comparable between methods (P ≥ 0.44).
