Priming of probabilistic attentional templates

A Kristjansson - Psychonomic Bulletin & Review, 2023 - Springer
Attentional priming has a dominating influence on vision, speeding visual search, releasing
items from crowding, reducing masking effects, and during free-choice, primed targets are …

Perception is rich and probabilistic

SB Jabar, D Fougnie - Scientific reports, 2022 - nature.com
When we see a stimulus, eg a star-shaped object, our intuition is that we should perceive a
single, coherent percept (even if it is inaccurate). But the neural processes that support …

How does color distribution learning affect goal-directed visuomotor behavior?

L Entzmann, ÁG Ásgeirsson, Á Kristjánsson - Cognition, 2025 - Elsevier
While the visual world is rich and complex, importantly, it nevertheless contains many
statistical regularities. For example, environmental feature distributions tend to remain …

I Makarov, SS Stefánsson Thors, EA Ævarsson… - ACM Transactions on …, 2023 - dl.acm.org
When two brief vibrotactile stimulations are sequentially applied to observers' lower back,
there is systematic mislocalization of the stimulation: if the second stimulation is of higher …

[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 …

Stronger serial dependence in the depth plane than the fronto-parallel plane between realistic objects: Evidence from virtual reality

ÖD Tanrikulu, D Pascucci, Á Kristjánsson - Journal of Vision, 2023 - jov.arvojournals.org
Visual estimates of stimulus features are systematically biased toward the features of
previously encountered stimuli. Such serial dependencies have often been linked to how the …

Representing Variability: How Do We Process the Heterogeneity in the Visual Environment?

A Chetverikov, Á Kristjánsson - Elements in Perception, 2024 - cambridge.org
The visual world is full of detail. This Element focuses on this variability in perception, asking
how it affects performance in visual tasks and how the variability is represented by human …

Probabilistic representations as building blocks for higher-level vision

A Chetverikov, Á Kristjánsson - arXiv preprint arXiv:2211.12591, 2022 - arxiv.org
Current theories of perception suggest that the brain represents features of the world as
probability distributions, but can such uncertain foundations provide the basis for everyday …

[HTML][HTML] Attentional priming in Go No-Go search tasks

Á Kristjánsson, T Kristjansson - Vision Research, 2023 - Elsevier
Abstract Go/No-Go responses in visual search yield different estimates of the operation of
visual attention than more standard present versus absent tasks. Such minor methodological …

Epistemic causality and its application to the social and cognitive sciences

Y Shan, SD Taylor, J Williamson - Alternative Approaches to …, 2024 - books.google.com
Just as the epistemic theory of probability (ie Bayesianism) interprets probability as a kind of
belief—namely, rational probabilistic belief—the epistemic theory of causality interprets …
