Unlocking crowding by ensemble statistics

Michael Herzog, David Pascucci, Oh-Hyeon Choung, Yury Markov, Natalia Tiurina

In crowding,1-7 objects that can be easily recognized in isolation appear jumbled when surrounded by other elements.8 Traditionally, crowding is explained by local pooling mechanisms,3,6,9-15 but many findings have shown that the global configuration of th ...

(Un)crowding is pre-attentive

Michael Herzog, Alban Bornet, Yury Markov, Natalia Tiurina

In crowding, perception of a target deteriorates in the presence of nearby flankers. Crowding can be undone when additional flankers are presented, an effect known as uncrowding, which occurs when the flankers group with each other and ungroup from the tar ...

Effects of item distinctiveness on the retrieval of objects and object-location bindings from visual working memory

Yury Markov

Visual working memory (VWM) is prone to interference from stored items competing for its limited capacity. Distinctiveness or similarity of the items is acknowledged to affect this competition, such that poor item distinctiveness causes a failure to discri ...

Serial dependence under memory load

Michael Herzog, David Pascucci, Ayberk Ozkirli, Gizay Ceylan, Yury Markov, Natalia Tiurina

Perceptual decisions are biased towards previous stimuli, a phenomenon known as serial dependence. However, the mechanisms of this bias are unknown. For example, it is debated whether serial dependence reflects a perceptual bias or interference of prior st ...
