Serial Dependence Predicts Generalization in Perceptual Learning

This study shows that serial dependence effects predict perceptual learning generalization by linking long-range memory traces to learning flexibility.

Motion-Induced Blindness as a Noisy Excitable System

The paper investigates whether Motion-Induced Blindness (MIB) operates as an excitable system, finding that target disappearance is triggered by masks and follows refractory dynamics.

Isolating objective and subjective filling-in using the Drift Diffusion Model

The paper uses the Drift Diffusion Model to analyze reaction-time data from target-flanker experiments, revealing RT-dependent and RT-independent effects of spatial context on decision-making.

Contrast adaptation improves spatial integration

The paper investigates how contrast adaptation affects spatial integration in a contrast discrimination task, finding that performance improvements are temporary and linked to adaptation reducing spatial noise.

A decision-time account of individual variability in context-dependent orientation estimation

The paper investigates individual variability in the tilt aftereffect (TAE) and finds that slower decision times correlate with reduced TAE magnitudes, suggesting decision-making flexibility explains some perceptual bias variability.

Interaction of contexts in context-dependent orientation estimation

The paper investigates how multiple contextual influences interact in visual orientation estimation, finding non-linear sub-additivity for adjacent contexts and linear additivity for temporally separated contexts.

Seeing, fast and slow: the effects of processing time on perceptual bias

The paper shows that perceptual biases decrease with longer reaction times and proposes a single-process stochastic model to explain this behavior.

Orientation-selective adaptation improves perceptual grouping

This study investigates how visual pattern adaptation affects perceptual grouping, finding that adaptation improves performance but is transient and susceptible to interference.

Real-time visual interactions across the boundary of awareness

The paper investigates whether visual representations can be modified without conscious perception by testing interactions between a consciously experienced and an unperceived stimulus.
