The Impact Of Focused Attention And Opening Monitoring Meditation Styles On Attention, Jennifer Wheary
Dissertations, Theses, and Capstone Projects
Mindfulness meditation – often broken down into two distinct types, focused attention (FA) and open monitoring (OM) – has been associated with a range of affective and attentional benefits. Using an attentional blink (AB) paradigm that demonstrated improved attention for novice FA meditators, we explored whether novices who engaged in a single, brief bout of meditation exhibited any differences in alpha or theta power during meditation, and whether these differences were apparent by meditation type. In the AB paradigm, participants are asked to identify two targets, T1 and T2, which are separated by 200-500 ms. Our results showed no significant …

Investigating Steady State Visually Evoked Potentials As A Novel Biosignature For Anxiety-Related Attention Bias, Elizabeth R. Davis

Anxiety-related attention bias (AB), a type of cognitive bias underlying the development and maintenance of anxiety disorders, is typically defined as exaggerated attention towards threat; however, some individuals also demonstrate AB away from threat and in some instances, no detectable AB at all. Debate about the reliability and validity of AB behavioral measures has prompted examination of additional assessment methods. Neurophysiological methods, such electroencephalography (EEG), have yielded encouraging early findings. The steady-state visually evoked potential (SSVEP), a measure of selective visual attention derived from EEG, holds promise as a biosignature for AB. Research documents heightened SSVEP power to emotionally salient …
