How Does Anxiety Affect Cognitive Control? Proactive And Reactive Control Under State Anxiety, Youcai Yang
How Does Anxiety Affect Cognitive Control? Proactive And Reactive Control Under State Anxiety, Youcai Yang
Theses and Dissertations
Cognitive control is a construct that prioritizes how we process stimuli and information and execute behaviors to flexibly and efficiently adapt to internal goals and external environmental changes. A recent theory, the Dual Mechanism of Control (DMC), distinguishes this phenomenon by two distinct cognitive control operations: proactive control and reactive control (Braver, 2012). Anxiety increases the allocation of attentional and working memory resources to threat-related stimuli, which impairs cognitive performance (Sarason, 1988), but additional work is needed to assess how anxiety impacts these two distinct forms of cognitive control. In this study, I examined how state anxiety affected proactive control, …
Moderating Effects Of Harm Avoidance On Resting-State Functional Connectivity Of The Anterior Insula, Ashley Ann Huggins
Moderating Effects Of Harm Avoidance On Resting-State Functional Connectivity Of The Anterior Insula, Ashley Ann Huggins
Theses and Dissertations
As an index of behavioral inhibition and an individual’s propensity to avoid, rather than seek, potentially dangerous situations, harm avoidance has been linked to internalizing psychopathology. Altered connectivity within intrinsic functional neural networks has been linked to internalizing psychopathology; however, less is known about the effects of harm avoidance on functional connectivity within and between these networks. Importantly, harm avoidance may be distinguishable from trait anxiety and have clinical relevance as a risk factor for psychopathology. To this end, the current study aimed to examine associations between harm avoidance and resting state functional connectivity. A sample of undergraduate students (n=92) …
