Intact and deficient contextual processing in schizophrenia patients

open access: yesSchizophrenia Research: Cognition, 2022
Schizophrenia patients are known to have deficits in contextual vision. However, results are often very mixed. In some paradigms, patients do not take the context into account and, hence, perform more veridically than healthy controls. In other paradigms,

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.

Feature tracking and aging

open access: yesFrontiers in Psychology, 2013
There are conflicting results regarding the effect of aging on second-order motion processing (i.e., motion defined by attributes other than luminance, such as contrast).

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 ...

The Historical Development of Easter-Southern Freight Rate Relationships [PDF]

open access: yes, 1947
A method for creating and presenting video-recorded synchronized audiovisual stimuli at a high frame rate-which would be highly useful for psychophysical studies on, for example, just-noticeable differences and gating-is presented.

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 ...

Perceived Azimuth Direction Is Exaggerated: Converging Evidence From Explicit And Implicit Measures [PDF]

open access: yes, 2016
Recent observations suggest that perceived visual direction in the sagittal plane (angular direction in elevation, both upward and downward from eye level) is exaggerated.

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.

MLP: a MATLAB toolbox for rapid and reliable auditory threshold estimation [PDF]

open access: yes, 2009
In this paper, we present MLP, a MATLAB toolbox enabling auditory thresholds estimation via the adaptive Maximum Likelihood procedure proposed by David Green (1990, 1993).

The Underestimation Of Egocentric Distance: Evidence From Frontal Matching Tasks [PDF]

open access: yes, 2011
There is controversy over the existence, nature, and cause of error in egocentric distance judgments. One proposal is that the systematic biases often found in explicit judgments of egocentric distance along the ground may be related to recently observed
