Neurobehavioral Changes in Macular Degeneration: Spatial Frequency Use in Scene Recognition Open
These findings demonstrate that macular diseases leads to altered spatial frequency processing within residual vision itself, particularly affecting fine-detail analysis. This perceptual degradation is accompanied by functional brain reorg…

Motion Processing in Visual Cortex of Maculopathy Patients Open
Previous studies on animal models suggested that visual areas involved in motion processing could undergo important cortical reorganizations following retinal damages. This could have major implications for patients suffering from macular …

Peripheral scene context influences the saccade toward an object in peripheral vision Open
Peripheral vision plays a crucial role in visual recognition, with previous studies suggesting that cognitive predictions from peripheral vision enhance object categorization in central vision during single eye-fixation. However, visual re…

Neural correlates underlying local and global processing during visual search across adulthood Open
Visual processing relies on the identification of both local and global features of visual stimuli. While well investigated at the behavioral level, the underlying brain mechanisms are less clear, especially in the context of aging. Using …

Interaction between central and peripheral vision: Influence of distance and spatial frequencies Open
Visual scene perception is based on reciprocal interactions between central and peripheral information. Such interactions are commonly investigated through the semantic congruence effect, which usually reveals a congruence effect of centra…

Radial bias in face identification Open
Human vision in the periphery is most accurate for stimuli that point towards the fovea. This so-called radial bias has been linked with the organization and spatial selectivity of neurons at the lowest levels of the visual system, from re…

Impact of glaucoma on the spatial frequency processing of scenes in central vision Open
Glaucoma is an eye disease characterized by a progressive vision loss usually starting in peripheral vision. However, a deficit for scene categorization is observed even in the preserved central vision of patients with glaucoma. We assesse…

Detection of emotional faces: the role of spatial frequencies and local features Open
Models of emotion processing suggest that threat-related stimuli such as fearful faces can be detected based on the rapid extraction of low spatial frequencies. However, this remains debated as other models argue that the decoding of facia…

It makes sense, so I see it better! Contextual information about the visual environment increases its perceived sharpness. Open
Predictive coding theories of visual perception postulate that expectations based on prior knowledge modulate the processing of information by sharpening the representation of expected features of a stimulus in visual cortex but few studie…

Considering the mixed nature of reports of flexibility difficulties in autism, we hypothesized that a task that more closely resembles the challenges faced in real life would help to assess these difficulties. Autistic and typically develo…

The Role of Emotional Content and Perceptual Saliency During the Programming of Saccades Toward Faces Open
Previous studies have shown that the human visual system can detect a face and elicit a saccadic eye movement toward it very efficiently compared to other categories of visual stimuli. In the first experiment, we tested the influence of fa…

Radial biases influence face identification in the periphery Open
In peripheral vision, humans have a better sensitivity to radial orientations (pointing towards the fovea) than to tangential ones (orthogonal to the fovea). We reasoned that due to these radial biases, objects perceived in peripheral visi…

Both high and low spatial frequencies are critical for visual consciousness in autism: Evidence of an emotional attentional blink paradigm. Open
High Spatial Frequencies (HSF - conveying local information) may serve a critical role in visual consciousness. Despite an HSF bias during visual perception in autism, autistic individuals demonstrate impairments in face processing. Our ai…

Theories of visual recognition postulate that our ability to understand our visual environment at a glance is based on the extraction of the gist of the visual scene, a first global and rudimentary visual representation. Gist perception wo…

Isolated face features are sufficient to elicit ultra-rapid and involuntary orienting responses toward faces Open
Previous studies have shown that face stimuli influence the programming of eye movements by eliciting involuntary and extremely fast saccades toward them. The present study examined whether holistic processing of faces mediates these effec…
