Far touch: integrating visual and haptic perceptual processing on wearables
… reduction ratios up to approximately 9:1 with no perceptual loss in typical scenarios. Also, we introduce a novel Gaussian foveation scheme that provides experimentally achievable gains up to approximately 2 times the compression ratio of typical compression schemes with less perceptual loss than …

Timecourse of a perceptual judgment and factors affecting it
Perceptual decisions are extremely fast and take on the order of milliseconds. The time taken to view the stimuli during these choices, termed processing time (PT), is an important quantity because it defines how informed, and thereby accurate, the choice is. Typically, the PT has been estimated …

Color and Texture Influences in Primed Object Categorization
… by texture and color with regard to conceptual processing was investigated using a priming paradigm. Using standardized sets of stimuli, priming techniques were utilized to investigate how one would typically acquire information and subsequently respond in the real world. A masked prime was …

The Parameters of Eye Movement in Vocal Music Reading (sight-Reading; Saccades)
… the study was to investigate selected aspects of perceptual processing of graduate music students reading melodies of varying levels of notational complexity. Six parameters of eye movement were measured using an SRI Eytracker: number of progressive and regressive fixations, progressive and …

The effects of normal ageing and processing style on explicit and implicit memory
… priming) declines or remains intact with age. Processing style is one primary factor that may explain this discrepancy: there is evidence that ageing does not affect conceptual (meaning-based) and perceptual (feature-based) processing equally, yet processing demands have varied in prior …

Perceptual and cognitive influences on decision making and the activity of single neurons in the superior colliculus and frontal eye field
… and finally use it to produce motor responses. Perceptual decision making is a field within systems neuroscience that aims to resolve how this process unfolds. In contrast to choice behavior and decision making in general, which are closely related concepts traditionally studied by …

Emotion Recognition of Dynamic Faces in Children with Autism Spectrum Disorder
… examining impaired emotion recognition and perceptual processing in autism spectrum disorders (ASD) show inconsistent results (Harms, Martin, & Wallace, 2010; Jemel, Mottron, & Dawson, 2006), and many of these studies include eye tracking data. The current study utilizes a novel task, …

What's odd? Cognitive processing of social contexts based on autistic traits within the general population
… in a cognitive framework; smaller differences in perceptual processing can snowball into tangible larger differences in complex and dynamic social situations (Benson, Castelhano, Howard, Latif & Rayner, 2016; Minshew & Goldstein, 1998). For example, individuals with ASD have a greater difficulty …

Different Pathways To Cognition: An Erp Investigation of Enhanced Perceptual Functioning And Autistic Traits in School-aged Children
<p>Autistic individuals show enhanced perceptual functioning on a range of behavioral tasks. Neurophysiological evidence, from both fMRI and event related potential (ERP) studies, also supports the conclusion that autistic individuals utilize perceptual processes to a greater extent than …

Visual Processing Across Space and Time in Children with Autism Spectrum Disorder
… spectrum disorder (ASD) demonstrate enhanced perceptual</p> <p>abilities relative to typically developing (TD) peers, as evidenced by better detection and identification of visual targets. This enhanced ability to discriminate features has been replicated across spatial and temporal displays. …

Face recognition ability in preterm or low gestational weight adults and children.
… the trajectory and plasticity of the face processing system from childhood to adulthood. In Experiment 1, adults (n = 94) completed four dominant tests of face and object recognition ability to assess their relevant perceptual and mnemonic skills, completed measures of social functioning, …

Neurobiology of incremental speech comprehension
… language requires the rapid transition from perceptual processing of the auditory input through a variety of cognitive processes involved in constructing the mental representation of the message that the speaker is intending to convey. Listeners carry out these complex processes very rapidly …

Interrogating the infant mind with fMRI
… the functional organization of higher-level perceptual and cognitive processes in infants’ brains. For two decades scientists have attempted to use functional magnetic resonance imaging (fMRI) to study infant perceptual and cognitive function. However, it remains unclear whether the basic …

Electrophysiological and Behavioural Markers of Associative Source Memory Decline in Normal Ageing

Visual Object-Category Processing with and without Awareness

NEURAL CORRELATES OF RANDOM AND INFORMED SACCADIC CHOICES IN THE MACAQUE FRONTAL EYE FIELDS AND CENTRAL THALAMUS
… saccade target selection, neural correlates of perceptual judgment and motor choice were evaluated for visuomotor neurons recorded in the FEF and OcTh. Monkeys performed a compelled-saccade task, a two-alternative forced-choice task that requires rapid perceptual judgments (color discrimination) …
