Risk prediction error signaling: A two-component response?
NeuroImage, 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.

Contemporary management of pain in cirrhosis: Toward precision therapy for pain
Hepatology, 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 ...

Specific Gestalt principles cannot explain (un)crowding
Frontiers 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 ...

Identifying Objective EEG Based Markers of Linear Vection in Depth
Frontiers 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 ...

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

Eye, 1988 New developments in clinical psychophysics allow a non-invasive assessment of visual function which may otherwise not be possible. Measurements of spatial and temporal contrast sensitivity functions, perimetric rod and cone sensitivity, colour vision testing, and newer tests such as hyperacuity thresholds may provide information about the mechanism of ...

Who Is the Founder of Psychophysics and Experimental Psychology?
American Journal of Islam and Society, 1999 The study is an investigation of the origins of psychophysics and experimental psychology. According to historians of psychology, Francis Bacon had the most crucial influence in the history of the experimental method, because he emphasized the importance
