Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray Sep 2019

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …


The Use Of Infographics To Assess Context Processing, Beliz Hazan Sep 2019

The Use Of Infographics To Assess Context Processing, Beliz Hazan

Dissertations, Theses, and Capstone Projects

Among high-order cognitive functions is the use of context to enhance comprehension of language or visual scenes. Although use of context is known to be impaired in certain clinical populations (e.g., schizophrenia), no existing test adequately assesses this construct. To fill this gap, we developed and attempted to validate a test of context use that employed Infographics (information graphics), which requires the use of context to interpret visual displays. The primary hypothesis was that interpreting Infographics would be sensitive to context processing. We further hypothesized that different levels of cognitive processing (requiring basic perceptual, real-world application, or verbal reasoning), as …
