EEG microstates are a candidate endophenotype for schizophrenia

open access: yesNature Communications, 2020
EEG microstate abnormalities have been reported in patients with schizophrenia. Here the authors demonstrate that patients and their siblings show similar microstate abnormalities compared to healthy controls.

Visual Aftereffect Of Texture Density Contingent On Color Of Frame [PDF]

open access: yes, 1996
An aftereffect of perceived texture density contingent on the color of a surrounding region is reported. In a series of experiments, participants were adapted, with fixation, to stimuli in which the relative density of two achromatic texture regions was ...

Who Is the Founder of Psychophysics and Experimental Psychology?

open access: yesAmerican 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

When are abrupt onsets found efficiently in complex visual search? : evidence from multi-element asynchronous dynamic search [PDF]

open access: yes, 1990
Previous work has found that search principles derived from simple visual search tasks do not necessarily apply to more complex search tasks. Using a Multielement Asynchronous Dynamic (MAD) visual search task, in which high numbers of stimuli could ...

Norwich’s Entropy Theory: how not to go from abstract to actual [PDF]

open access: yes, 2011
Purpose – The purpose of this paper is to ask whether a first-order-cybernetics concept, Shannon’s Information Theory, actually allows a far-reaching mathematics of perception allegedly derived from it, Norwich et al.’s “Entropy Theory of Perception”.

Feature integration within discrete time windows

open access: yesNature Communications, 2019
In order to perceive moving or changing objects, sensory information must be integrated over time. Here, using a visual sequential metacontrast paradigm, the authors show that integration occurs only when subsequent stimuli are presented within a ...

Unraveling brain interactions in vision: The example of crowding

open access: yesNeuroImage, 2021
Crowding, the impairment of target discrimination in clutter, is the standard situation in vision. Traditionally, crowding is explained with (feedforward) models, in which only neighboring elements interact, leading to a “bottleneck” at the earliest ...

Sensory Measurements: Coordination and Standardization [PDF]

open access: yes, 2015
Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical ...

The Role of Edges and Line-Ends in Illusory Contour Formation [PDF]

open access: yes, 1993
Illusory contours can be induced along directions approximately collinear to edges or approximately perpendicular to the ends of lines. Using a rating scale procedure we explored the relation between the two types of inducers by systematically varying ...

A Bayesian psychophysics model of sense of agency

open access: yesNature Communications, 2018
Sense of agency (SoA) refers to the experience or belief that one’s own actions caused an external event. Here we present a model of SoA in the framework of optimal Bayesian cue integration with mutually involved principles, namely reliability of action ...
