Externalizing and interpreting autonomic arousal in people diagnosed with autism
… assisting the interpretations of individuals' arousal states. First, the home-based study is a participant-driven study following Kanner's perspective of documenting "fascinating peculiarities" in autism. I arrive in a family as an ethnographer documenting a dynamic process of hypothesizing and …

Distinct forms of depression and somatization following head injury: A neuropsychological framework and exploratory treatment paradigm for somatic symptoms and executive dysfunction following mild head injury
… vulnerable in TBI, and serves to modulate autonomic arousal states. Varying severities of TBI have been linked to autonomic underarousal as measured by electrodermal activation (EDA). In a series of studies examining persons with mild head injury (MHI), the phenomenological presentation of …

Examining empathy in Autism Spectrum Disorders: cognitive, subjective and physiological correlates of the perception of pain
… and physiological. Particularly, measurement of autonomic regulation can contribute to characterising the empathy profile in ASD. Furthermore, confounding factors such as lack of understanding of one's own emotions, or alexithymia, must be accounted for when measuring empathy. I measured …

Sympathetic Arousal During Approach-Avoidance Decision- Making
… (EDA). EDA has been used widely to assess autonomic arousal during various paradigms. Research has demonstrated how autonomic arousal (1) occurs during the processing or anticipation of emotional stimuli and (2) may inform the decision-making process. Our research focused on investigation …

Threat Perception Alteration as an Effect of Use-of-Force Simulation Training
… with an increase in anxious symptoms and autonomic arousal as evidence, or b) the training will desensitize the participant to violence leading to decreased threat perception with decreased positive and negative affect, and decreased autonomic arousal as evidence. Evidence for the latter …

Individual Differences in Emotional Awareness and the Lateralized Processing of Emotion
… RH than left hemisphere (LH), suggesting higher autonomic arousal, and (2) a lack of differentiation by N400 of facial expressions over the posterior RH when interhemispheric communication was required. These effects were not correlated, indicating they occurred in different HA females. This may …

FEEL : a system for acquisition, processing and visualization of biophysiological signals and contextual information
… Activity (EDA) wrist sensors that measured their autonomic arousal levels. These users were requested to upload the sensor data and annotate it at the end of the day at first, and then after two days. One group of users had access to both the signal and the full contextual information collected by …

Chronic psychological and psychophysiological sequelae among adolescents following a traumatic bus crash
… survivors' HR standard deviations (an index of autonomic lability) F (1,14) = 5.21, P = .03 in response to the crash interview. Survivors' HR did not differ from controls' on the MA task. Findings are discussed theoretically and methodologically within the contexts of neurological and …

Cortical and autonomic modulation of attentional control /
… work has been done on the role of the ACC in autonomic regulation. Its connections through the vagus nerve to the sinoatrial node of the heart are thought to exert modulatory control over cardiovascular arousal. Therefore, ACC is not only responsible for the implementation of cognitive …

Clarifying the Nature of Pain-Related Anxiety: Implications for Assessment and Treatment of Chronic Musculoskeletal Pain
… and physiological reactivity to pain (e.g., autonomic arousal, nausea). AS (Reiss, Peterson, Gursky, & McNally, 1986) is the trait tendency to fear the physiological sensations of anxiety due to the belief such sensations signal imminent harm. Evidence suggests an association between AS and …

Generalized Anxiety Disorder Following Mild Head Injury: An Investigation into the Relationship Between Physiological Underarousal and Symptoms of Anxiety
… which in turn can attenuate physiological autonomic arousal and disrupt emotional regulation (Bechara, Damasio, & Damasio, 2000; Fisher, Rushby, McDonald, Parks, & Piguet, 2015; Pardini, Krueger, Raymont, & Grafman, 2010). Diminished levels of visceral feedback leaves one at a disadvantage …

Child maltreatment and its consequences. How child maltreatment experiences are connected to sleep, stress, and love
… a lower quality of sleep when grown up. The hyperarousal concept of insomnia is a widely accepted approach to explain difficulties with sleep initiation and maintenance. The model postulates that individuals suffering from insomnia have an increased baseline arousability on different levels. …

The pathophysiological mechanisms underlying metamemory disruptions
… examined the proposed relationship between autonomic function and metamemory abilities. In this study, I investigated whether blocking noradrenergic action using propranolol would remediate arousal-related disruptions to metamemory performance. It was hypothesised that heightened autonomic …
