The Expression Of Guilt, Chloe A. Stewart
The Expression Of Guilt, Chloe A. Stewart
Electronic Thesis and Dissertation Repository
Though aversive, the experience and expression of guilt is important to healthy social functioning. Guilt is often described as visceral, and nonverbal guilt expressions are anecdotally observed, yet much remains unknown about how guilt is expressed. The present work aimed to explore the visceral experience of guilt via the autonomic nervous system (ANS), and the nonverbal display of guilt via facial, gestural, and postural expressions. Using a novel film paradigm, we explored ANS activity during guilt in healthy adults and adults with neurodegenerative disorders (NDs). We further explored the nonverbal behaviours associated with guilt in healthy adults. We hypothesized that, …

The scoping review surveyed the existing literature on the topic of resting-state functional connectivity (rsFC) and mathematical cognition. The review revealed that rsFC is indicative of distinct long-term developmental trends in mathematical processing, alluding to individual differences in math abilities. Though there have been multiple studies that investigate individual differences in functional connectivity patterns related to math development and math learning disorders, no study has directly investigated to what degree these neurobiological factors are heritable. To address this topic, the following intergenerational transmission (IT) study is proposed. IT is the transfer of personal values, abilities, behaviours, and traits, from parents …
Familiarity As A Motivator For Information-Seeking, Danielle Raynes-Goldfinger
Familiarity As A Motivator For Information-Seeking, Danielle Raynes-Goldfinger
Undergraduate Student Research Internships Conference
Curiosity is an integral part of motivation and results in information-seeking behaviors to obtain rewarding information. Theories on curiosity suggest that it occurs when an information gap is detected. Here, we explored whether the assessment of familiarity may result in the induction of curiosity. We employed 3 phases, the first involving memorization of face-name pairs. Next, participants were presented with new and the old faces and were asked to judge whether they fully remembered the name, whether the face was familiar despite the name being unrecallable, or whether the face nor name was familiar. To conclude, we allowed participants to …
Does Aberrant Connectivity Underlie The Experience Of Misophonia?, Kate Raymond
Does Aberrant Connectivity Underlie The Experience Of Misophonia?, Kate Raymond
Electronic Thesis and Dissertation Repository
Misophonia is a condition characterized by an extreme aversion to certain ordinary sounds, such as chewing or breathing. These sounds are typically innocuous but elicit strong feelings of anger, anxiety, and disgust as well as physiological stress in people with misophonia. This misophonic reaction to “trigger” sounds is also marked by increased activity in regions of the brain that process sound, ascribe salience, and regulate emotion (Kumar et al., 2017; Schroder et al., 2019). It has therefore been theorized that aberrant connectivity between these brain regions (particularly the anterior insula, auditory cortex, amygdala, and hippocampus) may underlie the experience of …
Is Motor Excitability Modulated By Isochronous Rhythms?, Syed Z. Raza
Is Motor Excitability Modulated By Isochronous Rhythms?, Syed Z. Raza
Electronic Thesis and Dissertation Repository
Humans perceive and synchronize to regularity in auditory temporal sequences. Auditory regularity activates motor areas, but how the timing of motor responses relates to the regularity is unclear. Thus, we examined whether motor excitability, an index of motor activity, fluctuated to an isochronous sequence and characterized the timing of these fluctuations. Participants heard isochronous tones followed by a short silence, during which they imagined the tones continuing. Using single pulse transcranial magnetic stimulation (TMS), we indexed excitability throughout the sequence. Cosine models were fit to constructed excitability timecourses to quantify periodicity of the excitability fluctuations. Motor excitability did not fluctuate …
