The Dissociable Impact Of Auditory Vs. Visual Emotional Cues On Visual Processing, Emma K. Stewart Bsc, Derek Gv Mitchell Phd

Western Research Forum

Background: Emotional information has privileged access to processing resources, which can cause it to have a distracting or facilitating effect on task performance for reasons that are poorly understood. The sensory modality through which it is presented may be one determining factor. Some findings suggest that auditory stimuli facilitate visual task performance while visual stimuli interfere with it, but there are conflicting findings.

Hypothesis: We hypothesize that emotional content of a different sensory modality from the task improves task-related performance via a general alerting and arousing effect for all stimuli, while emotional content of the same modality disrupts performance when …

Spontaneous Mimicry Of Emotional Facial Expressions As A Function Of Trait Sadism, Cathleen Fleury, Mary Ritchie, Derek Mitchell

Western Research Forum

Using electromyography (EMG), it has been shown that facial muscles imperceptibly mirror the facial expressions of others, a phenomenon referred to as spontaneous facial mimicry. Facial mimicry may be involved in empathy processing, and is impaired in several empathy deficit disorders. It was previously believed to follow the direct-matching principle, a theory postulating that spontaneous facial mimicry involves the observer mirroring their partner’s expression exactly. However, several recent studies have demonstrated that context and individual differences may be influencing factors of spontaneous facial mimicry. In the present study, we propose to investigate the relationship between facial mimicry and empathy through …

Multisensory Integration And Autistic Traits Using Non-Sociolinguistic Information, Sébastien A. Lauzon, Samantha E. Schulz, Zack I. Cohen, Ryan A. Stevenson

Western Research Forum

Background: Sensory processing issues are one of the most common complaints in autism spectrum disorder (ASD). One area of sensory difficulties in ASD that has been the focus of intense research in recent years is multisensory integration (MSI), or the ability to bind auditory and visual information into a single, unified percept. While integration of social or linguistic information is consistently shown to be an area of difficulty in ASD, results are less clear with simple, non-sociolinguistic stimuli. This study aims to address this ambiguity by determining whether MSI of non-sociolinguistic sensory information is related to traits and symptomatology …

P24. The Birds And The Beats: Perception Of A Beat In An Avian Model, Brendon Samuels

Western Research Forum

Background: Beat perception is a complex cognitive skill that enables humans to “feel” the beat in music, and is an essential component of synchronization of behavior and dance. The mechanisms in the human brain that facilitate beat perception are not entirely understood, and have only been studied thus far using non-invasive techniques. Some animals, such as songbirds, also seem to be able to detect a beat in rhythms, though this has never been formally tested independent of motor synchronization.

Methods: An operant experiment is used to assess if European starlings, a type of songbird, are capable of categorizing …

P34. The Effects Of Standing Desks On Classroom Performance Of University Students, Siobhan Smith

Western Research Forum

Background:

It is well established that there are many health risks associated with prolonged sedentary time.¹ Unfortunately, research conducted on university students is limited but yet they experience excessive periods of sitting time during class and while studying.

Methods:

Recently, we investigated the effect of sitting, dynamic sitting, and standing desks on classroom performance of university students.² Participants performed three 3-minute classroom simulations, one for each of the three desks. The order of the desks and simulations were randomized. Each of the simulations included a different typing and memory task.

Results:

Results showed no significant difference in the …
