Interhemispheric communication during face processing
… do not operate in isolation during the processing of complex visual stimuli. Patterns of interhemispheric communication are believed to be integral to cognitive abilities yet despite this, both the circumstances under which communication takes and the nature of the information that can …

3D face processing for animation and biometrics
In this dissertation we study core problems in 3D face processing with their important applications in biometrics and graphics. We propose efficient and accurate feature based algorithms for facial feature detection, 3D model fitting and tracking from static and dynamic 2D and 3D visual signal …

Electrophysiological investigations of the timing of face processing
As important social stimuli, faces playa critical role in our lives. Much of our interaction with other people depends on our ability to recognize faces accurately. It has been proposed that face processing consists of different stages and interacts with other systems (Bruce & Young, 1986). At a …

Face Processing Strategies in Children with Autism Spectrum Disorder
… aim of this thesis was to investigate the face processing strategies of children with high-functioning autism. Based on the assumptions that face processing relies on holistic, configural and featural information processing of faces, and on previous findings that individuals with autism …

Three-Dimensional Face Processing and Its Applications in Biometrics
… which resulted in the largest static 3D face database and the first audiovisual 3D dynamic face data collection system in the world; (2) a robust, fast and accurate 3D face reconstruction and animation algorithm, which can be used to create an emotive speech avatar; and (3) the …

Neural correlates of extended dynamic face processing in neurotypicals
… brain patterns resulting from prolonged dynamic face stimuli. The brain waves from neurotypical subjects were recorded using the electroencephalography (EEG) while viewing a series of 10 second long video clips. These clips were one of two categories: face or non-face. Modern signal processing …

Atypical Lateralization of Language and Face Processing in Autism Spectrum Disorder
… and restricted interests. Language and face processing are areas of domain-specific dysfunction impacting social interaction in ASD. Brain function associated with these cognitive domains is typically lateralized across the cerebral hemispheres, such that language and face processing are …

Ultra-Fast and Multi-Dimensional Face Processing in a New Face Area
<p>Faces contain a plethora of information crucial for social interactions. Facial information could be transmitted either through facial shape or motion. The last two decades have established that a network of face-selective areas in the temporal lobe of macaque monkeys supports the visual …

Effects of Temporal and Spatial Context Within the Macaque Face-Processing System
… play a key role in vision as a whole, and in face perception specifically. However, little is known about the neurophysiological mechanisms by which contextual cues exert their effects. Anatomically distinct face patches in the macaque brain analyze facial form, and studies of the activity …

The own-group bias in face processing: the effect of training on recognition performance
The own-group bias in face recognition (OGB) is the greater facility to distinguish and recognize people from one's own group at the expense of people from other-groups. The OGB has been studied for many years, however, very little research focuses on finding a way to decrease or eliminate it, …

Appearance based modeling and learning of the human face with application to biometrics
In this dissertation we study key problems in face processing, with a focus on the applications in biometrics, including both hard biometrics (i.e. conventional face recognition) and soft biometrics, where demographical attributes (e.g. gender and age) are recognized. We categorize face processing …

Towards a unified account of face (and maybe object) processing
Faces are an important class of visual stimuli, and are thought to be processed differently from objects by the human visual system. Going beyond the false dichotomy of same versus different processing, it is more important to understand how exactly faces are processed similarly or differently from …

Electrophysiological indices of the violence inhibition mechanism and their associations with physical agression, callous-unemotional traits, and dietary omega-3
… in order to tease apart the distinct stages of face processing and distress-induced motor extinction using electroencephalography. Results suggested that whilst callous-unemotional traits, specifically uncaring traits, were associated with electrophysiological indices of structural/featural face …

The Influence of Media Violence on the Neural Correlates of Empathic Emotional Response
… behavior. Researchers suggest that emotional face processing and inhibitory control may be important factors associated with aggressive behavior and empathy; however, few researchers have examined these variables in chronic and nonchronic violent video game players. Therefore, the goal of the …

A neuroscientific and cognitive examination of individual differences in face recognition ability
There are large individual differences in face processing ability, with Super-Recognisers (SRs) being exceptionally superior to individuals with average face recognition ability. This thesis describes seven experiments examining SRs’ cognitive performance as well as neural/electrical activity in …

Face recognition ability in preterm or low gestational weight adults and children.
Face recognition impairments can present throughout life as a result of acquired or developmental influences. While existing evidence implicates genetics and early visual deprivation, little is known about how other early influences may impact the development of the face recognition system. Very …

Cerebral hemodynamic response to faces and emotions in infants at high risk for autism
… two years of age. A lack of normal attention to faces and abnormal face processing is a cognitive deficit common to nearly all individuals with autism spectrum disorder, and this deficit is likely present from a very early age. The primary goal of this dissertation is therefore to characterize …

Intermediate Level Mechanisms Supporting Face Perception
… the intermediate neural mechanisms involved in face processing may be better understood by studying concentric form-from-structure integration. This dissertation involves behavioral adaptation and masking experiments that provide evidence regarding whether face perception and concentric …

MEG correlates of visual perception : the M170 response to degraded face and building images
Introduction: Knowing how the brain processes faces is valuable to scientists, clinicians, and industry How does seeing a face eventually lead to recognition: e.g. "that's Jill." Many reports (including this one) are interested in this question, due to its intrinsic scientific appeal and …
