Explicit access to detailed representations of feature distributions
The human visual system can quickly process groups of objects (ensembles) and build compressed representations of their features. What does the conscious perception of ensembles consist of? Observersʼ explicit access to ensemble representations has been considered very limited – any distributional aspects beyond simple summary statistics, such as the mean or variance, cannot be explicitly accessed. In contrast, we demonstrate that the visual syst…
New data on text reading in English as a second language: The Wave 2 expansion of the Multilingual Eye-Movement Corpus (Meco)
This paper reports an expansion of the English as a second language (L2) component of the Multilingual Eye Movement Corpus (MECO L2), an international database of eye movements during text reading. While the previous Wave 1 of the MECO project (Kuperman et al., 2023) contained English as a L2 reading data from readers with 12 different first language (L1) backgrounds, the newly collected dataset adds eye-tracking data on English text reading from…
How does color distribution learning affect goal-directed visuomotor behavior
Priming of probabilistic attentional templates
Temporal integration of feature probability distributions
Musical expertise, musical style, and visual attention
Research has repeatedly demonstrated that people with experience within a particular domain have exceptional cognitive abilities for domain-specific information. Chess masters, for instance, are far better at memorizing visually presented chess positions than amateurs, and professional American football experts are highly sensitive to semantic changes in domain-related scenes. However, for non-domain-related material, experts’ performance becomes…
Feature distribution learning by passive exposure
Humans can rapidly estimate the statistical properties of groups of stimuli, including their average and variability. But recent studies of so-called Feature Distribution Learning (FDL) have shown that observers can quickly learn even more complex aspects of feature distributions. In FDL, observers learn the full shape of a distribution of features in a set of distractor stimuli and use this information to improve visual search: response times (R…
The selection balance: Contrasting value, proximity and priming in a multitarget foraging task
What kind of empirical evidence is needed for probabilistic mental representations? An example from visual perception
Dynamics of visual attention revealed in foraging tasks
Probabilistic rejection templates in visual working memory
Are Foraging Patterns in Humans Related to Working Memory and Inhibitory Control
In previous studies we have shown that human foraging patterns appear to be constrained by attention. However, we also noted clear individual differences in foraging ability, where some individuals can apparently keep more than one target template in mind during foraging. Here, we examine whether such individual differences relate to more general working memory capacity and/or the ability to inhibit a primed, or prepotent response. We had three m…
