Machilsen B, Wagemans J, Demeyer M
Vision Res
. 2015 Jul;
126:207-219.
PMID: 26130605
Perceptual grouping processes are typically studied using sparse displays of spatially separated elements. Unless the grouping cue of interest is a proximity cue, researchers will want to ascertain that such...

. 2014 Jun;
14(5):11.
PMID: 24879858
Research has shown that contour detection is impaired in the visual periphery for snake-shaped Gabor contours but not for circular and elliptical contours. This discrepancy in findings could be due...

Neuroimage
. 2013 Nov;

PMID: 24269572
To study the dynamics of contour integration in the human brain, we simultaneously acquired EEG and fMRI data while participants were engaged in a passive viewing task. The stimuli were...

Annu Int Conf IEEE Eng Med Biol Soc
. 2013 Oct;
2013:6019-22.
PMID: 24111111
Multimodal approaches to brain imaging are getting increasingly popular among the neuroscience comunity. One such multimodal approach is the combination of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). In...

Iperception
. 2013 Jun;
4(1):36-52.
PMID: 23799186
We investigated the role of spatial arrangement of texture elements in three psychophysical experiments on texture discrimination and texture segregation. In our stimuli, oriented Gabor elements formed an iso-oriented and...

Iperception
. 2013 Mar;
3(10):745-64.
PMID: 23483752
We previously tested the identifiability of six versions of Gaborized outlines of everyday objects, differing in the orientations assigned to elements inside and outside the outline. We found significant differences...

Iperception
. 2012 Nov;
1(3):121-42.
PMID: 23145218
Using outlines derived from a widely used set of line drawings, we created stimuli geared towards the investigation of contour integration and texture segmentation using shapes of everyday objects. Each...

Behav Res Methods
. 2011 Nov;
44(2):439-46.
PMID: 22101655
To study perceptual grouping processes, vision scientists often use stimuli consisting of spatially separated local elements that, together, elicit the percept of a global structure. We developed a set of...

PLoS One
. 2011 Sep;
6(9):e25151.
PMID: 21949875
We investigated how the electrophysiological signature of contour integration is changed by the context in which a contour is embedded. Specifically, we manipulated the orientations of Gabor elements surrounding an...

Vision Res
. 2010 Nov;
51(1):179-86.
PMID: 21093469
In studies of shape perception, the detection of contours and the segregation of regions enclosed by these contours have mostly been treated in isolation. However, contours and surfaces somehow need...
