Where the last interval lingers: the putamen and duration serial dependence
Si Cheng’s fMRI study in NeuroImage: Reports finds that the previous interval lingers in the putamen, not visual cortex, when people reproduce durations, and that task switching recruits …
Research
Distinct hippocampus codes for contextual cueing
Siyi Chen’s brain-imaging study in NeuroImage shows the anterior hippocampus encoding links between a repeated context and the target, the posterior hippocampus encoding relations among …
Research
Domain-specific vs domain-general prediction errors
Plank and colleagues find in Imaging Neuroscience that adults with ASD, ADHD and neurotypical controls show no differences in prediction-error signals for the colors and emotions of unattended faces, …

How Distractors Summon but Do Not Engage Attention
Shao-Yang Tsai’s high-density EEG study in Cortex shows that distractors sharing the target’s critical features capture spatial attention, marked by a larger N2pc, yet evoke no late PD, …

 Large-Scale Benchmarking Reveals Optimal Metrics for Measuring Functional Connectivity in Aging
Benchmarking 20 resting-state fMRI connectivity metrics on 1187 participants, a NeuroImage study with NICUM finds correlational and distance-based measures most sensitive to age-related connectivity …
Research
Distinct Neural Mechanisms of Contextual Guidance and Suppression
Siyi Chen’s EEG study in The Journal of Neuroscience shows that a predictive distractor layout triggers a guidance mode with N1pc, N2pc and CDA signatures, while a non-predictive layout switches …

How does saccade distort the time we experience?
Lingyue Chen’s study in Psychological Research shows that a saccade not only stretches the first event seen afterwards but also compresses the next one, a tug-of-war that intensifies the …
Research
Atypical Prior Updating in ASD
In a duration reproduction task, individuals with ASD updated their prior expectations more strongly from each new sensory input than controls, especially in volatile settings, challenging the …

Conscious Awareness Boosts Dynamic Regularity Learning in Visual Search
Hao Yu’s eye-tracking study in Cognition shows that people who consciously noticed the target’s predictable shift in serial search sent their first saccade to the predicted location, …
Research
How do we learn and use dynamic spatial patterns in visual search?
When a search target shifted to an adjacent position on 80 percent of trials, about 70 percent of participants learned the pattern, but only those aware of it searched faster with fewer saccades.
Research
How tasks shape temporal sequential dependence
Dr. Si Cheng and colleagues show in Psychological Research that duration judgments drift toward the previous trial, and this pull grows when consecutive trials both require reproduction, but not in a …
Research
Opposing sequential biases in time and direction perception
Si Cheng found that reproduced durations are pulled toward the previous trial while reproduced directions are pushed away, and both biases grow when the task cue arrives after the stimulus rather than …
Research
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 …
Research
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 …
Research
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 …
Research
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 …
Research
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.

Influence of Temporal and Probabilistic Expectation on Subjective Time of Emotion Stimulus
Karaaslan and Shi report in the Quarterly Journal of Experimental Psychology that images arriving earlier than expected feel briefer, rare images feel longer, and negative images outlast neutral ones, …
Research
Influence of Temporal and Probabilistic Expectation on Subjective Time of Emotion Stimulus
Karaaslan and Shi found that emotional images arriving earlier than expected felt shorter, rarer ones felt longer, and negative images seemed to last longer than neutral ones, with expectancy and …

Workshop on “Predictive Attention” Yields Insightful Discussions
Dr. Siyi Chen of LMU CAS gathered speakers from Lancaster, Oxford, Nijmegen, Peking, Columbia and Amsterdam for a two-day workshop, 18-19 March 2024, debating how our minds anticipate and react to the …

High demand redirects increased anxiety to uphold goal-directed attention
Experimentally raised state anxiety left dual-target search performance unchanged: high task demand and working memory load appear to redirect anxiety and keep attention goal-directed rather than …
Research
Influence of Action on Sequential Dependence
An fMRI study in Cerebral Cortex shows that prior durations bias current time judgments only after active reproduction, not passive viewing, with hippocampal activity shielding encoded durations from …

Eye movement: innovation in visual perception training
Training vision while the eyes move lets perceptual learning spread beyond the trained spot to untrained parts of the visual field, LMU Newsroom reports on the PNAS study by Grzeczkowski, Shi, Rolfs …

Feng Meng, can the ability to see a flea as large as a wheel be transferred?
Lukasz Grzeczkowski shows in PNAS that perceptual learning transfers to a new location when the eyes saccade there, though not to a new feature, told through the Chinese myth of archer Feng Meng.
