Effects of behavioral tasks on memory reconsolidation and trauma-related symptoms : a randomized clinical trial
… Recent studies suggest that visuospatial tasks (e.g., Tetris) may disrupt the reconsolidation of fear memories and may have clinical utility for the treatment of PTSD. The overarching objective of this dissertation was to investigate the effects of a visuospatial task on memory …

The Effect of Injury Severity on Behavioral Tasks Used for the Assessment of Cognitive Functioning Following Traumatic Brain Injury
… following traumatic brain injury (TBI), yet the behavioral tasks used to assess cognitive behavior in rodent models of brain injury are underrepresented in the field. Additionally, few of these tasks have been used to assess behavior across degrees of injury severity. The goal of the present …

12-Item Depression, Anxiety, And Stress Scales (Dass-12): Associations With Self-Report Measures, A Semi-Strcutured Interview, And Behavioral Tasks
… DASS instrument is able to predict responses to behavioral tasks and whether the DASS was able to produce hypothesized convergent and divergent relationships with relevant self-report measures. Second, I examined how well the DASS predicted diagnoses gleaned from semi-structured interviews. …

Behavioral inhibition and test anxiety: an empirical investigation of Gray's theory
The effects of test anxiety on behavioral inhibition were examined using three computerized behavioral tasks. High test anxious subjects demonstrated more behavioral inhibition than low test anxious subjects, according to frequency measures on two of the three behavioral tasks. Group differences in …

Simultaneous Behavior Onset Detection and Task Classification for Patients with Parkinson Disease Using Subthalamic Nucleus Local Field Potentials
… the models for classification of different behavioral tasks performed by PD patient. The detection is based on recorded Local Field Potentials (LFP) of the Subthalamic nucleus (STN), captured through Deep Brain Stimulation (DBS) process.</p> <p>One main part of this work is dedicated to the …

Arousal theory and the interrelationships of caffeine, nicotine and impulsivity
… (double-blind). Participants engaged in three behavioral tasks: the Stop Signal Task (SST), the Stroop Color-Word Test (SCWT), and the Delay Discounting Task (DDT). Drug intake did not produce significant changes across conditions on any of the three tasks. The hypothesis that caffeine and …

MEMORY AND DEFAULT NETWORK ACTIVATION AS A FUNCTION OF APOE GENOTYPE
… of this dissertation project was to assess the behavioral and neural correlates of Episodic Memory as a function of the APOE genotype in a healthy young adult sample. To accomplish this, 98 subjects completed behavioral tasks assessing visual memory, working memory, episodic memory, and …

The Effect Of Cooperative Gameplay On Aggression And Prosociality In Violent Video Game Play
… again. Data were then collected on behavioral tasks measuring aggression and prosociality. This experiment failed to find significant effects of violent video game exposure on aggression. Participants who played a violent video game cooperatively scored higher on self-report scales …

Neurobehavioral mechanisms of social cognition and emotion regulation: A behavioral and functional brain imaging approach
… a comprehensive understanding of the neurobehavioral mechanisms associated with these socioemotional processes would provide unique insights into the factors that may render individuals susceptible to or resilient against socioemotional distress. Despite significant advances in cognitive …

Building an Allocentric Traveling-Direction Signal Via Vector Computation
<p>Many behavioral tasks require the manipulation of mathematical vectors, but, outside of computational models, it is not known how brains perform vector operations. Here we show how the Drosophila central complex, a region implicated in goal-directed navigation, performs vector arithmetic. First, …

Monoaminergic Signaling in the Human Brain: New Insights
… systems cooperate to shape cognitive and behavioral processes remains a central challenge in neuroscience. The monoamines dopamine, serotonin and norepinephrine uniquely contribute to neural computations throughout the forebrain, influencing attention, learning and decision-making. …

Spatiotemporal brain imaging and modeling
… network during the execution of cognitive and/or behavioral tasks. Advanced noninvasive medical imaging modalities are able to locate brain activities at high spatial and temporal resolutions. Quantitative modeling of these data is needed to understand how large-scale distributed neuronal …

FUNCTIONAL ROLES OF MIDBRAIN DOPAMINE NEURONS IN ASSOCIATIVE LEARNING
… from dopamine neurons in the context of behavioral tasks capable of dissociating activity relating to stimulus salience from that which predicts reward value. Results from these studies reveal a biphasic neural response and suggest that dopamine neurons both encode the occurrence of …

Binge Alcohol Effects on the Prefrontal Cortex
… and quantity as well as prefrontal- dependent behavioral tasks following binge alcohol exposure. To assess this, adult male and female Long-Evans rats were assigned to binge or control groups and exposed to ethanol using a well-established 4-day model of alcohol-induced neurodegeneration. Both …

Growth Trajectories of Neurocognitive Self-Regulation and Adolescent Adjustment
… At each time point, adolescents completed three behavioral tasks that capture the underlying dimensions of EF, and both adolescents and their primary caregiver completed measures of adolescent symptomatology. Parallel process growth curve modeling was used to test the associations between initial …

Individual Differences in Zebrafish (<i>Danio rerio</i>) Behavior: Implications for Personality
… traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in …

Role of NMDA in the Visual Working Memory of the Macaque Monkey
… during the memory retention intervals of various behavioral tasks. Computational and cellular physiology has suggested that this persistent activity depends on NMDA receptor activation. Indeed, pharmacological studies on both human and animal subjects have reported a significant decrease in …

Different Pathways To Cognition: An Erp Investigation of Enhanced Perceptual Functioning And Autistic Traits in School-aged Children
… 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 neurotypical comparisons to support …

Cognitive Ability and Cognitive Style in the Comprehension and Expression of Emotion
… posterior cortex.</p><p>In the present study 31 behavioral tasks comprised a scale to assess the ability to communicate affect by non-verbal means. The tasks assessed the comprehension and/or expression of affect in facial expressions, drawings of faces, intonations of neutral sentences, and …
