How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Full-text available
Integration to boundary is an optimal decision algorithm that accumulates evidence until the posterior reaches a decision boundary, resulting in the fastest decisions for a target accuracy. Here, we demonstrated that this advantage incurs a cost in metacognitive accuracy (confidence), generating a cognition/metacognition trade-off. Using computatio...

We examine the ability of observers to extract summary statistics (such as the mean and the relative-variance) from rapid numerical sequences of two digit numbers presented at a rate of 4/s. In four experiments (total N = 100), we find that the participants show a remarkable ability to extract such summary statistics and that their precision in the...

We examine the ability of human observers to estimate the average of rapid serial visual presentational (RSVP) sequences of numerical symbols at rates of up to 30 items/sec. In three experiments (2 pilots and 1 pre-registered replication), we find that observers extract the average of fast RSVP sequences (which they “barely see”) with a precision t...

Full-text available
Recent research has established that humans can extract the average perceptual feature over briefly presented arrays of visual elements or the average of a rapid temporal sequence of numbers. Here we compared the extraction of the average over briefly presented arrays, for a perceptual feature (orientations) and for numerical values (1-9 digits), u...

Full-text available
Humans and animals are capable of estimating and discriminating nonsymbolic numerosities via mental representation of magnitudes—the approximate number system (ANS). There are two models of the ANS system, which are similar in their prediction in numerosity discrimination tasks. The log-Gaussian model, which assumes numerosities are represented on...

Integration-to-boundary is an optimal decision algorithm that takes samples of evidence until the posterior reaches a decision boundary, resulting in the fastest decisions for a target accuracy. For example, integration-to-boundary achieves faster mean-RT compared with taking a fixed number of samples that result in the same choice-accuracy. Here w...
Preprint
Recent research has established that humans can extract average of perceptual features from sets of briefly and simultaneously presented elements or the average of rapid temporal sequences of numerical values. Here we compare the extraction of the average of simultaneously presented sets of perceptual features (orientations) and of numerical values...
