Research within visual cognition has made tremendous strides in uncovering the basic
operating characteristics of the visual system by reducing the complexity of natural vision to …

Dissociating implicit and explicit ensemble representations reveals the limits of visual perception and the richness of behavior

S Hansmann-Roth, Á Kristjánsson, D Whitney… - Scientific reports, 2021 - nature.com
Our senses provide us with a rich experience of a detailed visual world, yet the empirical
results seem to suggest severe limitations on our ability to perceive and remember. In recent …

Conscious and unconscious processing of ensemble statistics oppositely modulate perceptual decision-making.

D Liu, W Liu, X Yuan, Y Jiang - American Psychologist, 2023 - psycnet.apa.org
Our visual system possesses a remarkable ability to extract summary statistical information
from groups of similar objects, known as ensemble perception. It remains elusive whether …

You see what you look for: Targets and distractors in visual search can cause opposing serial dependencies

M Rafiei, A Chetverikov, S Hansmann-Roth… - Journal of …, 2021 - jov.arvojournals.org
Visual perception is, at any given moment, strongly influenced by its temporal context—what
stimuli have recently been perceived and in what surroundings. We have previously shown …

[HTML][HTML] Extracting statistical information about shapes in the visual environment

S Hansmann-Roth, A Chetverikov, Á Kristjánsson - Vision Research, 2023 - Elsevier
It is well known that observers can use so-called summary statistics of visual ensembles to
simplify perceptual processing. The assumption has been that instead of representing …

Temporal integration of feature probability distributions

S Hansmann-Roth, S Þorsteinsdóttir, JJ Geng… - Psychological …, 2022 - Springer
Humans are surprisingly good at learning the statistical characteristics of their visual
environment. Recent studies have revealed that not only can the visual system learn …

[HTML][HTML] Testing temporal integration of feature probability distributions using role-reversal effects in visual search

ÖD Tanrıkulu, A Chetverikov, A Kristjansson - Vision Research, 2021 - Elsevier
The visual system is sensitive to statistical properties of complex scenes and can encode
feature probability distributions in detail. But does the brain use these statistics to build …

What kind of empirical evidence is needed for probabilistic mental representations? An example from visual perception

ÖD Tanrıkulu, A Chetverikov, S Hansmann-Roth… - Cognition, 2021 - Elsevier
Recent accounts of perception and cognition propose that the brain represents information
probabilistically. While this assumption is common, empirical support for such probabilistic …

The influence of the tested item on serial dependence in perceptual decisions

M Rafiei, A Chetverikov, S Hansmann-Roth… - …, 2023 - journals.sagepub.com
Serial dependence in vision reflects how perceptual decisions can be biased by what we

Priming effect of individual similarity and ensemble perception in visual search and working memory

W Lin, J Qian - Psychological Research, 2024 - Springer
Perceptual priming is a well-known phenomenon showing that the repetition of an object's
feature can facilitate subsequent detection of that item. Although the priming effect has been …
