Blocked versus interleaved: How range contexts modulate time perception and its EEG signatures
Dr. Baykan and colleagues report in Psychophysiology that blocking short and long intervals, instead of interleaving them, sharpens time estimates and produces faster, stronger CNV buildup plus a …

Impact of Contextual Guidance and Suppression on Visual Search Efficiency
Siyi Chen’s visual search study in Psychonomic Bulletin & Review shows that learned context-target associations speed search strongly but break down when reversed, whereas context …

Selective contextual association
EEG recordings by Artyom Zinchenko and Xuelian Zang show that repeated distractor layouts speed search only for one dominant target, marked by early N1pc and N2pc, while a second target evokes a later …

Talk on Visual distractor suppression at Oldenburg University
At Oldenburg University, hosted by Prof. Hans Colonius, Dr. Zhuanghua Shi presented EEG and fMRI evidence that same-dimension distractors slow search and dampen the N2pc, while cross-dimension color …

Understanding Color Perception: How Natural Daylight Cues Influence Hue Discrimination
Hue discrimination is most accurate and least biased along the color axis matching natural daylight; a Bayesian observer model with a prior favoring blue tones explains the pattern, published in …

How range contexts modulate time perception and its EEG signatures
Presenting short and long intervals in separate blocks, rather than mixed, yields more accurate time estimates and a faster, stronger CNV buildup, as an EEG study led by Dr. Cemre Baykan shows.

New insights into Vierordt’s law: A talk by Prof. John Wearden
Prof. John Wearden came to Munich to revisit Vierordt’s Law, weighing internal-clock and contextual accounts of why we overestimate short intervals and underestimate long ones, and argued that …
