Risk prediction error signaling: A two-component response?

open access: yesNeuroImage, 2020
Organisms use rewards to navigate and adapt to (uncertain) environments. Error-based learning about rewards is supported by the dopaminergic system, which is thought to signal reward prediction errors to make adjustments to past predictions.

Specific Gestalt principles cannot explain (un)crowding

open access: yesFrontiers in Computer Science, 2023
The standard physiological model has serious problems accounting for many aspects of vision, particularly when stimulus configurations become slightly more complex than the ones classically used, e.g., configurations of Gabors rather than only one or a ...

Contemporary management of pain in cirrhosis: Toward precision therapy for pain

open access: yesHepatology, EarlyView., 2022
Abstract Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health‐related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding ...

Stimulus frequency alone can account for the size effect in number comparison

open access: yesActa Psychologica, 2023
In a number comparison task, the size effect (i.e, smaller values are easier to compare than larger values) is usually attributed to a psychophysics-based representation.

The Irreducibility of Vision: Gestalt, Crowding and the Fundamentals of Vision

open access: yesVision, 2022
What is fundamental in vision has been discussed for millennia. For philosophical realists and the physiological approach to vision, the objects of the outer world are truly given, and failures to perceive objects properly, such as in illusions, are just

Identifying Objective EEG Based Markers of Linear Vection in Depth

open access: yesFrontiers in Psychology, 2016
This proof-of-concept study investigated whether a time-frequency EEG approach could be used to examine vection (i.e., illusions of self-motion). In the main experiment, we compared the event-related spectral perturbation (ERSP) data of 10 observers ...
