Neural correlate of the Thatcher Face Illusion in a monkey face-selective patch KU Leuven
Compelling evidence that our sensitivity to facial structure is conserved across the primate order comes from studies of the "Thatcher face illusion": humans and monkeys notice changes in the orientation of facial features (e.g., the eyes) only when faces are upright, not when faces are upside down. Although it is presumed that face perception in primates depends on face-selective neurons in the inferior temporal (IT) cortex, it is not known ...
Perceiving where another person is looking: The integration of head and body information in estimating another persons gaze KU Leuven
The process through which an observer allocates his/her attention based on the attention of another person is known as joint attention. To be able to do this, the observer effectively has to compute where the other person is looking. It has been shown that observers integrate information from the head and the eyes to determine the gaze of another person. Most studies have documented that observers show a bias called the overshoot effect when ...
Neural Correlates of Aggression in Medication-Naive Children with ADHD: Multivariate Analysis of Morphometry and Tractography KU Leuven
Aggression is widely observed in children with attention deficit/hyperactivity disorder (ADHD) and has been frequently linked to frustration or the unsatisfied anticipation of reward. Although animal studies and human functional neuroimaging implicate altered reward processing in aggressive behaviors, no previous studies have documented the relationship between fronto-accumbal circuitry-a critical cortical pathway to subcortical limbic ...
Considering Too Few Alternatives: The Mental Model Theory of Extensional Reasoning KU Leuven
When solving a simple probabilistic problem, people tend to build an incomplete mental representation. We observe this pattern in responses to probabilistic problems over a set of premises using the conjunction, disjunction and conditional propositional connectives. The Mental Model Theory of Extensional Reasoning explains this bias towards underestimating the number of possibilities: In reckoning with different interpretations of the premises ...
Assessing multisensory tasting experiences by means of customized soundscapes KU Leuven
We review three methods, which are all intended to address the influence of sound on the perception of taste. In the analysis of the results of the first method, we take into account the added value of a progressive interaction of the participants in their perceptual experiences. Furthermore, with two new methods that we introduce, we intend to elaborate on the claim that customized sonic cues can have a significant influence on taste, and in ...
Capturing peripersonal spatial neglect: An electronic method to quantify visuospatial processes KU Leuven Universiteit Gent
Computerized as well as paper-and-pencil tasks are applied in mapping visuospatial neglect in experimental research and clinical practice. This article presents a new kind of computer-based assessment method, using an electronic pen display and user-friendly software. The approach is tailored to specific spatial processes and highlights the usefulness of a pen display in neglect patients. The advantages of the introduced method are illustrated ...
The effect of face inversion for neurons inside and outside fMRI-defined face-selective cortical regions KU Leuven
It is widely believed that face processing in the primate brain occurs in a network of category-selective cortical regions. Combined functional MRI (fMRI)-single-cell recording studies in macaques have identified high concentrations of neurons that respond more to faces than objects within face-selective patches. However, cells with a preference for faces over objects are also found scattered throughout inferior temporal (IT) cortex, raising the ...
