Effects of perceptual and decisional uncertainty on serial dependence in orientation perception.

ABSTRACT: Where assimilative serial dependence occurs in perception, responses to visual attributes such as orientation are typically biased towards the attributes of visual stimuli seen in the recent past. Serial dependence is thought to increase the signal-to-noise ratio of visual representations and is reliably increased by uncertainty in the target stimulus. However, the amount of uncertainty in the preceding inducer stimulus does not seem to modulate serial dependence. Here, we consider whether uncertainty in the decision made about the inducer stimulus modulates serial dependence instead by using stimuli with high positive evidence (high-contrast signal plus high-contrast noise) and low positive evidence (low-contrast signal and low-contrast noise). Such stimuli are matched in their signal-to-
