From: Adaptation reveals multi-stage coding of visual duration
Monocular vs binocular contributions to duration processing. (A) Schematic showing the final four ‘top-up’ (fixed duration) adapting stimuli. The subsequent test phase comprised a fixed duration auditory tone (red sinusoid) followed by a variable duration visual test stimulus presented to the same or opposite eye. In the above example of a ‘different eye’ trial, relatively long duration adapting stimuli are presented to the right eye only followed by the presentation of moderate duration test stimuli to the left eye only (see Methods for details). (B,C) Individual and group mean Point of Subjective Equality (PSE) values representing the test durations that were perceptually equivalent to the auditory reference stimulus after adaptation to relatively long (666 ms - yellow bars) or short (166 ms - blue bars) visual durations. Longer PSE values reflect perceptual compression of test stimulus duration. Red horizontal lines denote veridical duration perception. Data are shown for conditions where adapting and test stimuli were presented to the same (B) or different (C) eyes. Throughout, error bars represent bootstrapped 95% CIs.
