EEG frequency tagging dissociates target and flanker processing in crowding

Flankers can strongly deteriorate performance on a target (crowding). The neural mechanisms of crowding are largely unknown. We have recently shown that the N1 component of the EEG is suppressed during crowding. Because it is difficult to disentangle the n ...

Crowding, grouping, timing

Michael Herzog, Aaron Michael Clarke, Mauro Manassi, Vitaly Chicherov

In crowding, target perception is deteriorated by flanking elements. For example, when a vernier is flanked by two lines of the same length, vernier offset discrimination strongly deteriorates. Interestingly, changing the color of the flankers can reduce c ...

Neural correlates of visual crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In visual crowding, target discrimination strongly deteriorates when flanking elements are added. We have recently shown that crowding cannot be explained by simple low-level interactions and that grouping is a key component instead. We presented a vernier ...

Electrophysiological correlates of suppression and facilitation in crowding

Michael Herzog, Vitaly Chicherov

In crowding, neighboring elements deteriorate performance on a target. The neural mechanisms of crowding are largely unknown. We have recently shown that the N1 component of the EEG is suppressed during crowding. It is difficult to disentangle the processi ...

Electrophysiological signatures of crowding are similar in foveal and peripheral vision

Michael Herzog, Vitaly Chicherov

Flankers can strongly deteriorate performance on a visual target (crowding). For example, vernier offset discrimination strongly deteriorates when neighbouring flankers are presented. Interestingly, performance for longer and shorter flankers is better tha ...

Crowding suppresses the N1 wave

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Flankers can strongly deteriorate performance on a visual target (crowding). For example, vernier offset discrimination is strongly affected by neighboring flankers. Interestingly, performance for longer and shorter flankers is better than performance for ...

The N1 wave amplitude reflects perceptual grouping and correlates with crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In crowding, flanking elements strongly deteriorate performance. For example, vernier offset discrimination is strongly affected by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

The time course of perceptual grouping: a high density ERP study

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Performance on a target can be strongly modified by context. For example, vernier offset discrimination is strongly deteriorated by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...
