Moments That Matter: The Role Of Emotional Stimuli At Event Boundaries In Memory, Haonan Chen

Senior Projects Spring 2023

The present study examined the impact of event segmentation and emotional arousal on long-term memory performance. Event segmentation is the cognitive process of automatically dividing experiences into smaller pieces for better consolidation and retrieval, resulting in the formation of event boundaries. Prior research has identified the crucial role of event segmentation in long-term memory and working memory. However, few studies have explored ways to enhance its effects. Emotional arousal refers to the physiological and psychological activation of the body and mind in response to an emotional stimulus. Previous research has indicated that heightened levels of arousal may enhance memory performance. …

The Effects Of Music-Induced Emotion On Memory, Jessica C. Rylander

Senior Projects Spring 2022

Emotion can play a highly influential role when it comes to enhancing memory. Research has shown that emotional valence and emotional arousal are two key aspects of emotion responsible for facilitating this (APA, 2013). However, various studies have found contradicting results when it comes to which type of valence (positive or negative) and which level of arousal (high or low) have the greatest memory enhancing effects. Similarly, the majority of previous research has specifically investigated this emotion-memory relationship in terms of memory for emotional content. The present study aims to address this gap by separating emotion from the to-be-learned stimuli, …

Classical Conditioning Of Cognitive States, Arthur Burns

Neuroscience Presentations

This research sought out to do preliminary testing to prepare for honors research in the 2021 academic year. This research focuses on attempting to classically condition cognitive states. Learning tasks were designed to elicit relaxation or arousal in partisans and a combination of EEG data, pupil dilation data, performance on cognitive tasks, and self-report were used to evaluate the level of cognitive states in participants.

The Effect Of Color On Time Perception And Task Performance, Jake Hensz, Max Hart, Melissa Banuelos, Chad Shire

STEM Student Research Symposium Posters

Program: BS in Psychological Science

IRB#: Pro2018000277

The current study investigates the relationship between color and time perception. Prior research suggests that red stimuli create a greater temporal distortion than other colors, and that the direction of the distortion (i.e. underestimation or overestimation) varies with context. Research also shows that red stimuli tend to have negative effects on performance in academic contexts, perhaps due to the psychological and physiological arousal. This study specifically investigates the effect of arousal on this relationship, being the first to investigate the relationship between red, time perception, arousal, and task performance on a concurrent task …

Jealousy? Or Just Hostility Toward Other Dogs? The Risks Of Jumping To Conclusions, James A. Serpell

Animal Sentience

Cook et al. (2018) provide a fascinating demonstration of amygdala activation in dogs when they witnessed their owners giving food to another (fake) dog, but not when they placed food in a bucket. Dogs’ neurological responses were positively correlated with their reported levels of ‘dog-directed aggression’ as measured by the C-BARQ, and dogs with initially strong amygdala responses habituated on subsequent trials. The authors interpret their findings as possible evidence for an emotion akin to jealousy in dogs. However, alternate interpretations involving either dog aggression/fear or emotional responses to food seem more plausible and avoid the welfare risks associated with …

Towards A Physio-Cognitive Model Of Slow-Breathing, Chris Dancy

Faculty Conference Papers and Presentations

How may controlled breathing be beneficial, or detrimental to behavior? Computational process models are useful to specify the potential mechanisms that lead to behavioral adaptation during different breathing exercises. We present a physio-cognitive model of slow breathing implemented within a hybrid cognitive architecture, ACT-R/Φ. Comparisons to data from an experiment indicate that the physiological mechanisms are operating in a manner that is consistent with actual human function. The presented computational model provides predictions of ways that controlled breathing interacts with mechanisms of arousal to mediate cognitive behavior. The increasing use of breathing techniques to counteract effects of stressors makes it …

The Effects Of Affective Arousal On Color Perception And Memory, Nicole Elizabeth Lang

Senior Projects Spring 2016

The link between affective arousal, color perception, and color memory was explored by inducing fear, sadness, or embarrassment in 158 participants who them completed a color perception and memory task. It was predicted that participants experiencing fear or embarrassment would more often correctly identify and remember red and green than a neutral condition whereas experiencing sadness would lead to less correct identification and memory for blue and yellow than neutral. There was only a marginally significant effect of fear on color memory for red. In the low arousal condition, there was an effect of fear on color memory for green …

The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn

Undergraduate Honors Theses

The presence of music is a visceral part of the human experience and its influence on cognitive function is a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of mood and arousal and their influence on attention, thus the purpose of this study. Fifty undergraduate students currently enrolled at the University of Western Ontario were recruited for this study. Given that music is a highly subjective experience, participants rated an assortment of music clips on …

In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of these perceptual properties and their influence on attentional processes.

Given that music is a highly subjective experience, participants were asked to rate different music clips on independent dimensions of …

Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson

Graduate Theses and Dissertations

When an eyewitness suffers an impairment of memory for a criminal's face because the criminal used a weapon during the commission of the crime, this impairment is called the weapon focus effect. Literature provides two explanations for how this effect arises: some implicate the narrowing of attentional cues to the weapon during the commission of a crime because arousal of the victim increases, while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a …
