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 ...

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).

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 ...

Pre-stimulus alpha activity modulates long-lasting unconscious feature integration

open access: yesNeuroImage, 2023
Pre-stimulus alpha (α) activity can influence perception of shortly presented, low-contrast stimuli. The underlying mechanisms are often thought to affect perception exactly at the time of presentation.

Long-range coupling of prefrontal cortex and visual (MT) or polysensory (STP) cortical areas in motion perception [PDF]

open access: yes, 2010
To investigate how, where and when moving auditory cues interact with the perception of object-motion during self-motion, we conducted psychophysical, MEG, and fMRI experiments in which the subjects viewed nine textured objects during simulated ...

The psychophysics of imagery [PDF]

open access: yesPerception & Psychophysics, 2000
A series of experiments considers the extent to which the interrelations among subjective magnitudes aroused by images corresponds to those for subjective magnitudes aroused by physical stimuli. In Experiment 1, 68 undergraduates typed phrases in response to graded categories regarding the imagined magnitude of lights, sounds, and smells. In Experiment

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.
