Proactive And Reactive Cognitive Control Under Threat Of Unpredictable Shock: A Combined Eye-Tracking And Eeg Study Using Multilevel Modeling, Salahadin Lotfi Dec 2020

Proactive And Reactive Cognitive Control Under Threat Of Unpredictable Shock: A Combined Eye-Tracking And Eeg Study Using Multilevel Modeling, Salahadin Lotfi

Theses and Dissertations

We are constantly bombarded by environmental distractors in daily life which interfere with internal, ongoing goals, thus cognitive control processes need to be in place to adapt to maintain these goals in light of the environmental demands. These cognitive processes (generally referred to cognitive control) are thought to be adjusted reactively or proactively to deal with distractors. There is little evidence on how state anxiety dynamically interacts with these two modes of cognitive control. Taking advantage of a multimodal methodology, through two experiments, we replicated existing findings of reactive and proactive control processes via utilizing a Flanker task in a …


Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth Dec 2020

Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth

Doctoral Dissertations

Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …


Emotion Regulation And N2 Amplitude During A Go/Nogo Task: An Erp Study, Emily Tolar Dec 2020

Emotion Regulation And N2 Amplitude During A Go/Nogo Task: An Erp Study, Emily Tolar

Psychological Science Undergraduate Honors Theses

Emotion regulation is how people respond to and manage their reactions to life experiences, including resolving conflict between variable responses. Past research has associated the N2, an event-related potential associated with resolving response conflict, with both emotion regulation and negative emotion. However, to the best of our knowledge, no one has assessed if different emotion-regulation strategies are differentially associated with N2 activation. To assess this question, we conducted an EEG study with 147 participants. Participants completed the Cognitive Emotion Regulation Questionnaire (CERQ) and then played the go/no-go game as their EEG data was collected. The relationship between N2 amplitude and …


Modulation Of P3 And The Late Positive Potential Erp Components By Standard Stimulus Restorativeness And Naturalness, Salif P. Mahamane Dec 2020

Modulation Of P3 And The Late Positive Potential Erp Components By Standard Stimulus Restorativeness And Naturalness, Salif P. Mahamane

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tests of attention restoration theory (ART) consistently support that exposure to restorative environments can replenish finite cognitive resources, needed to focus attention, from a depleted state. These environments are usually natural, but the dimensions of naturalness and restorativeness are not one and the same, and yet have not been empirically delineated. The restorative effect has been documented in children and adults. However, neuroscientists have barely begun to test for neural correlates of ART. In this dissertation, I employ electroencephalography (EEG) to record electrophysiological brain activity during an active visual oddball task to capture and analyze p3 elicitation and late positive …


Threat-Induced Alterations In Cognition And Associations With Disinhibited Behavior, Julia B. Mcdonald Feb 2020

Threat-Induced Alterations In Cognition And Associations With Disinhibited Behavior, Julia B. Mcdonald

USF Tampa Graduate Theses and Dissertations

When a threat is detected, brain networks associated with threat processing are activated while other processes are deprioritized. While this resource allocation is adaptive, it makes it especially difficult to effortfully direct thoughts, emotions, and behaviors (use cognitive control) during situations of high stress. Further, this threat response is most efficient in response to short-term or predictable stressors (“threats”) but loses its efficiency for ambiguous or unpredictable threats. Despite research that suggests that threat induces psychological states associated with breakdown in cognitive control processes, no study has directly examined how predictability of threat impacts neurocognitive indicators of cognitive control processes. …


Digital Technologies As Antecedents To Process Integration And Dynamic Capabilities In Healthcare: An Empirical Investigation, Tulika Chakravorty, Karunakar Jha, Sunil Barthwal, Samyadip Chakraborty Jan 2020

Digital Technologies As Antecedents To Process Integration And Dynamic Capabilities In Healthcare: An Empirical Investigation, Tulika Chakravorty, Karunakar Jha, Sunil Barthwal, Samyadip Chakraborty

Journal of International Technology and Information Management

Healthcare has been in focus over the past decade due to its criticality and continuous revolution. In this digital era, with the advent of various technologies, healthcare is undergoing a massive transformation. This study attempts to analyze the impacts of three major digital technologies which are being adopted in the healthcare sector which are electronic medical records (EMR), enterprise resource planning (ERP) and internet-of-things (IoT) enabled medical wearables in the hospital context. Focusing towards analyzing the impact of these technologies towards process-integration and further towards dynamic capabilities like quality, agility and responsiveness; the study framework is well-grounded by two theoretical-underpinnings …


What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul Jan 2020

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …
