Spontaneous Intrapersonal Synchrony And The Effect Of Cognitive Load, Ramkumar Jagadeesan
Spontaneous Intrapersonal Synchrony And The Effect Of Cognitive Load, Ramkumar Jagadeesan
Electronic Thesis and Dissertation Repository
Spontaneous intrapersonal synchronization is the spontaneous synchronization of periodic behaviors within an individual. It is less investigated than spontaneous interpersonal synchronization, the synchronization of periodic behaviors that occurs spontaneously between individuals integrated into a single system through coupling, caused by the exchange of sensory feedback between them. It was therefore hypothesized that periodic behaviors produced by an individual, a single system by default, would spontaneously be more synchronous through exchange of sensory feedback, coupling and integration within the individual, when the behaviors are produced simultaneously, compared to separately. Based on a postulate that explains spontaneous interpersonal synchronization as a strategy …
Individual Differences In Categorization, Urooj Anees
Individual Differences In Categorization, Urooj Anees
Undergraduate Student Research Internships Conference
The appearance of individual differences used to be regarded as noise in psychological experiments, but is slowly becoming a tool used to enhance and solidify findings in various fields of cognitive psychology. This presentation aims to very briefly discuss individual differences and categorization and what questions future research could aim to answer.
Auditory Sensory Filtering And Development In Children With Autism Spectrum Disorder, Hiruthika Ravi, Ala Seif, Ryan A. Stevenson
Auditory Sensory Filtering And Development In Children With Autism Spectrum Disorder, Hiruthika Ravi, Ala Seif, Ryan A. Stevenson
Undergraduate Student Research Internships Conference
Sensory filtering is the process of separating and distilling relevant sensory information from irrelevant, which in turn greatly reduces the quantity of sensory information that is fully processed and leads to significant increases in efficiency. Atypical sensory filtering can result in sensory hypo- or hypersensitivity — atypical sensory filtering and hypo/hypersensitivity have been observed in people with autism. Atypical sensory filtering contributes to canonical symptoms in Autism.
Sensory filtering can be measured in a few different ways, one of which is the Acoustic Startle Response (ASR). ASR is a reflexively produced muscular reaction to sudden auditory stimuli.
Our study aims …
Culture And Classification: Investigating Analytic Vs. Holistic Thinking Styles, Neha Khemani
Culture And Classification: Investigating Analytic Vs. Holistic Thinking Styles, Neha Khemani
Electronic Thesis and Dissertation Repository
This paper sought to explore cultural preferences for analytic and holistic thinking in classification. Experiment 1 paired the Shepard, Hovland, and Jenkins (SHJ) tasks with the Analysis-Holism scale (AHS) and a demographics questionnaire. Effects of culture on learning rates, alongside the feasibility of online data collection, were assessed. Learning difficulty differences among the six SHJ category sets were observed. Further, as predicted, higher holistic thinking correlated positively with the family resemblance task. Experiment 2 replicated the Norenzayan et al. (2002) task. Unlike in the original study, the effect of instructional condition was not significant across our full sample. Nevertheless, the …
Temperament And Individual Differences In Category Learning, Tianshu Zhu
Temperament And Individual Differences In Category Learning, Tianshu Zhu
Electronic Thesis and Dissertation Repository
Objectives. Individuals can differ in their strategic approach in learning the same categorization task, researchers have sought to study what specific stable individual differences traits can help explain these differences. This dissertation first surveyed extant literature on the impact of trait differences on category learning then examined the effect of temperament traits on these dependent variables. Chapter 2 (scoping review): This scoping review synthesized the past literature that examined the relationship between sources of stable individual differences and category learning performance and strategy use outcomes. Five database platforms were searched to identify relevant articles, cross-referencing was also performed. Sixty-nine studies …
Seeing Thro The Musical Eye: Santo Daime, Fuke-Shū, 1960s Psychedelia, And The Antipodes Of Musical Experience, Forest Anthony-Muran
Seeing Thro The Musical Eye: Santo Daime, Fuke-Shū, 1960s Psychedelia, And The Antipodes Of Musical Experience, Forest Anthony-Muran
Electronic Thesis and Dissertation Repository
This thesis investigates the relationships between altered states of consciousness and the musical experience in religious tradition and practice. A common accompaniment to religious worship and ceremony, music is often used as a way of attempting to capture something of the ineffable and to help bring about a mystical experience. In this thesis, I make use of three contrasting case studies – the Brazilian syncretic religion Santo Daime, the historical branch of Zen Buddhism Fuke-shū, and the psychedelic rock of 1960s counterculture – to paint a portrait of the variety of ways that music has been used in different musical …
Optimizing Music Learning: The Effects Of Contextual Interference On Memorization, Carmen Andrea Wong
Optimizing Music Learning: The Effects Of Contextual Interference On Memorization, Carmen Andrea Wong
Undergraduate Honors Theses
The purpose of this study was to assess if blocked or interleaved practice learning was more effective for memorizing music, and to assess if metacognitive judgements aligned with performance. The study included 21 proficient pianists who regularly engage in piano practice. Participants learnt two excerpts and two technical studies, and played them from memory on both day 1 and day 2 of testing. Performances were recorded and rated by an expert in the field on a percentage scale. A two-way repeated measures ANOVA analysis revealed no significant main effect of day on practice schedule, (F(1,20) = .15, p = 0.70, …
The Role Of Top-Down Attention In Statistical Learning Of Speech, Stacey Reyes
The Role Of Top-Down Attention In Statistical Learning Of Speech, Stacey Reyes
Electronic Thesis and Dissertation Repository
Statistical learning (SL) refers to the ability to extract regularities in the environment and has been well-documented to play a key role in speech segmentation and language acquisition. Whether SL is automatic or requires top-down attention is an unresolved question, with conflicting results in the literature. The current proposal tests whether SL can occur outside the focus of attention. Participants either focused towards, or diverted their attention away from an auditory speech stream made of repeating nonsense trisyllabic words. Divided-attention participants either performed a concurrent visual task or a language-related task during exposure to the nonsense speech stream, while control …
A Sense Of Proportion: How Humans Process Relative Magnitudes In Space And Time, Rebekka Lagace-Cusiac
A Sense Of Proportion: How Humans Process Relative Magnitudes In Space And Time, Rebekka Lagace-Cusiac
Electronic Thesis and Dissertation Repository
Humans perceive ratios for different spatial magnitudes such as length, area, and numerosity, and temporal magnitudes such as duration. Previous studies have shown that spatial ratios may be processed by a common ratio processing system. The aim of the current study was to determine whether ratios across spatial and temporal domains may also be processed by a common system. Two hundred and seventy-five participants completed a series of spatial and temporal ratio estimation and magnitude discrimination tasks. Structural equation modeling (SEM) was used to analyze the relationship between ratio processing across domains when controlling for absolute magnitude processing ability. Results …
Does Culture Affect The Ability To Learn And Use Categories?, Maya Ghai, Zarah Ghulamhussain
Does Culture Affect The Ability To Learn And Use Categories?, Maya Ghai, Zarah Ghulamhussain
Undergraduate Student Research Internships Conference
The rapid advancement of cross-cultural research in recent decades has raised questions on the extent to which findings in cognitive psychology can be generalized to a global population. The majority of subjects in scientific literature, being WEIRD (Western, educated, industrialized, rich, and democratic) populations, only represent a sliver of the world’s diverse demographics, limiting our scope of psychological data to a highly specific subgroup. Emerging research has made us increasingly aware of the variances in cognition across cultures, including the learning and utilization of categories. Many lab-based categorization tasks have demonstrated that cognitive processes may be contingent on cultural factors. …
Neural Representation Of Stimulus Category Membership Across Modalities, Carson Rumble-Tricker
Neural Representation Of Stimulus Category Membership Across Modalities, Carson Rumble-Tricker
Undergraduate Student Research Internships Conference
Category learning is a process through which common features among category members, distinctive features among non-members, or even both, are identified (Hammer et al., 2009). This process is a critical aspect of cognition and can guide decision making and information inference. Furthermore, category learning is involved among a large number of stimuli, including visual (Folstein et al., 2013), auditory (Ley et al., 2012), olfactory (Qu et al., 2016), and multisensory (Viganòa, Borghesani, & Piazza, 2021) stimuli.
The aim of this systematic review is to determine and qualitatively analyze studies that investigate the changes in the neural representations of stimuli that …
Likelihood And Familiarity In The Simulation Of Future Events, Claudia Morales Valiente
Likelihood And Familiarity In The Simulation Of Future Events, Claudia Morales Valiente
Electronic Thesis and Dissertation Repository
Episodic future thinking is the ability to project the self forward in time to pre-experience an event (Atance & O’Neill, 2001). Understanding how people think about potential future events is an important component of human memory research. We investigated whether and how episodic future thinking is influenced by a person's belief of the likelihood of its future occurrence in their lives, as well as a person's familiarity with that type of event based on their past experience. The combined and individual effects of these variables have been minimally studied, particularly likelihood. We used three norming studies to develop participant-specific sets …
Visual Perception In Hearing Sign Language Users, Jessica M. Lammert
Visual Perception In Hearing Sign Language Users, Jessica M. Lammert
Electronic Thesis and Dissertation Repository
Deaf signers exhibit superior visual perception compared to hearing controls in several domains, including the perception of faces and peripheral motion. These visual enhancements are thought to compensate for an absence of auditory input. However, it is also possible that they reflect experience using a visual-manual language, where signers must process complex moving hand signs and facial cues simultaneously. Thus, the current study sought to isolate the effects of sign language experience by examining how visual perception is altered as a function of American Sign Language (ASL) proficiency in hearing individuals. Hearing signers completed an online test of ASL proficiency …
Using Cognitive Dissonance To Encourage Covid-Preventive Behaviours, Xuanqiao Wang
Using Cognitive Dissonance To Encourage Covid-Preventive Behaviours, Xuanqiao Wang
Brescia Psychology Undergraduate Honours Theses
This study investigated whether a hypocrisy-based intervention would increase students’ intentions to engage in COVID-preventive behaviours. We hypothesized that participants in the hypocrisy-induction condition (experimental condition) would express higher levels of intention to engage in COVID-preventative behaviours than participants in whom hypocrisy has not been induced (control condition). The sample consisted of 2 male and 64 female undergraduate students at Brescia University College. An independent t-test was conducted on the intention rating scores of practicing COVID-preventative behaviours for the experimental and control conditions. It was found that there was no significant difference in the average intention rating score between the …
Individual Differences In Cognitive Flexibility And Cognitive Map Accuracy, Vanessa C. Cunha
Individual Differences In Cognitive Flexibility And Cognitive Map Accuracy, Vanessa C. Cunha
Brescia Psychology Undergraduate Honours Theses
Research has demonstrated broad individual differences in the ability to form a cognitive map of a novel environment. The current study investigated whether individual differences in cognitive map accuracy are driven by differences in cognitive flexibility specifically, the ability to switch between tasks. Using the Silcton virtual environment, participants explored four routes in Silcton and were assessed on cognitive map accuracy using the Silcton onsite pointing task and the Silcton model building task. To assess task-switching, perseveration error from the Wisconsin Card Sort Test (WCST) was measured. There was a significant correlation between the WCST and the onsite pointing task, …
Interpreting Intentions: Evidence For Cross-Language Influences In Bilinguals, Maziyah Mohamed
Interpreting Intentions: Evidence For Cross-Language Influences In Bilinguals, Maziyah Mohamed
Electronic Thesis and Dissertation Repository
In Malay, accidental actions are marked with the prefix -ter. Malay speakers typically assume a deliberate intent when the prefix is absent. I investigated whether Malay-English bilinguals are more likely than English monolinguals to interpret actions in English sentences as deliberate when they are not clearly indicated as being accidental. In Experiment 1, Malay speakers completed a recognition memory task. The results showed that Malay speakers remembered unintentionality accurately. This accuracy in remembering unintentionality suggests that Malay speakers encode the intentions of others. In Experiment 2, participants completed a cross-modal priming task. They first heard scenarios in which a …
Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo
Characterizing The Familiar-Voice Benefit To Intelligibility, Beatriz Ysabel Domingo
Electronic Thesis and Dissertation Repository
Everyday listening often occurs in the presence of background noise. Listeners with normal hearing can often successfully segregate competing sounds from the signal of interest. To do this, listeners exploit a variety of cues to facilitate the separation of simultaneous sounds into separate sources, and group sequential sounds into intelligible speech streams. One of the cues that has been shown to be an effective facilitator of speech intelligibility is familiarity with a talker’s voice. A recent study by Johnsrude et al. (2013) measured speech intelligibility of a naturally familiar voice (i.e., that of a long-term spouse) and showed a …
Cross-Linguistic Effects Of Intention Recognition In Malay Bilinguals, Maziyah Mohamed, Debra Jared
Cross-Linguistic Effects Of Intention Recognition In Malay Bilinguals, Maziyah Mohamed, Debra Jared
Western Research Forum
Does the language we speak influence the way we interpret intentions of others? Prior literature has shown that obligatory markers in a language may influence the way we think. In Malay texts, accidental actions are marked using a prefix. Malay speakers are, thus, quick to identify the accidental actions of others. Conversely, it may be that Malay speakers often interpret intentions as deliberate given a more ambiguous context where the prefix is absent. The goal of the current study was to determine whether this way of interpreting one’s intentions of others extends to English texts for Malay-English bilinguals. In Study …
The Effects Of Linguistic Labels On Object Categorization And Perception, Xuan Pan
The Effects Of Linguistic Labels On Object Categorization And Perception, Xuan Pan
Electronic Thesis and Dissertation Repository
The linguistic relativity hypothesis (Whorf, 1956) claims that speakers of different languages perceive and conceptualize the world differently. Language-thought interaction is likely to be more complex in bilinguals because they have two languages that could influence their cognitive and perceptual processes.Lupyan’s (2012) Label-feedback Hypothesis proposes a mechanism underpinning language-thought interactions, arguingthat linguistic labels affect our conceptual and perceptual representations through top-down feedback.This thesis tested the Label-feedback Hypothesis by capitalizing on an interesting feature of Chinese. In English, most nouns do not provide linguistic clues to their categories (an exception issunflower), whereas in Chinese, some nouns provide explicit category …
The Effects Of Semantic Priming On Lexical Processing, Alexander Taikh
The Effects Of Semantic Priming On Lexical Processing, Alexander Taikh
Electronic Thesis and Dissertation Repository
The present experiments were designed to investigate the locus of the semantic priming effect, a phenomenon that has received much research attention. Semantically related primes (e.g., cat) might activate the lexical representations of their targets (e.g., DOG) through automatic spreading activation at short stimulus onset asynchronies (SOAs) between the prime and target, or through generation of words expected to follow the prime at long SOAs. Alternately, semantically related primes might be used strategically to aid responding after target identification. The effects of masked orthographic primes (e.g., judpe-JUDGE), in contrast, are assumed to be strictly lexical and automatic. Lexical processing of …
The Cognitive Psychology Of Humour In Written Puns, James Boylan
The Cognitive Psychology Of Humour In Written Puns, James Boylan
Electronic Thesis and Dissertation Repository
The primary purpose of this dissertation was to investigate how humour from written puns is produced. Prior models have emphasized that novel or surprising incongruities should be important to humour appreciation (Suls, 1972; Topolinski, 2014). In study 1, a new approach to operationalizing incongruity as semantic dissimilarity was developed and tested using Latent Semantic Analysis (Landauer, Foltz & Laham, 1998). “Latent semantic incongruity” was associated with humour ratings, but only for puns with low ratings of familiarity from a prior occasion or for those with a low level of aggressive content. Overall, there was also an unexpected strong positive association …
Semantic Processing Of Nominal Metaphor: Figurative Abstraction And Embodied Simulation, Hamad Al-Azary
Semantic Processing Of Nominal Metaphor: Figurative Abstraction And Embodied Simulation, Hamad Al-Azary
Electronic Thesis and Dissertation Repository
In a metaphor such as that lawyer is a shark, the concept lawyer, which is the metaphor topic, and the concept shark, which is the metaphor vehicle, interact to produce a figurative meaning such that lawyers are predatory. Some theorists argue that sensorimotor properties of the vehicle are the basis of metaphor comprehension (Gibbs & Matlock, 2008; Paivio, 1979; Wilson & Gibbs, 2007). As such, that lawyer is a shark is processed by an embodied simulation where sensorimotor imagery associated with sharks is simulated (e.g., sharks hunting in deep water). However, the long-standing assumption is that metaphors are …
The Validity Of Inferring Real-World Cognitive Mapping Ability Based On Performance In A Virtual Environment, Chantelle M. Cocquyt
The Validity Of Inferring Real-World Cognitive Mapping Ability Based On Performance In A Virtual Environment, Chantelle M. Cocquyt
Brescia Psychology Undergraduate Honours Theses
This study investigated whether virtual environments (VE) have ecological validity in studies of cognitive mapping ability. Forty female undergraduate students completed the spatial orientation test (SOT) and other tasks that assessed their cognitive of real-world locations they visit often and a VE, through direction estimation and map accuracy tasks. Participants had lower error scores on real-world direction estimation than VE direction estimation, suggesting that the accuracy of their cognitive maps was associated with familiarity and exposure to an environment. Real-world direction estimation, VE direction estimation, and VE map building were all correlated with the SOT, suggesting a shared reliance on …
Popular Music-Evoked Autobiographical Memories - Developing A Database Of Songs And Studying The Role Of Cue Emotionality And Relevance On Recalled Memories, Krysten Zator
Electronic Thesis and Dissertation Repository
In Study 1, undergraduate students rated popular music songs on several factors. A database of knowledge was created for popular music autobiographical memory (AM) cueing research. Study 2 examined the role of emotional experience and relevance associated with a popular music AM cue on recalled AMs. In Phase 1, undergraduate participants described AMs to short music clips or a blank computer screen (control). In Phase 2, participants answered questions about these AMs. In Phase 3, participants rated musical clips (including Phase 1 stimuli). Unexpectedly, music-cued memories were less salient and did not differ emotionally from control-cued, but contained more perceptual …
Social Media And Cognition, Ana C. Ruiz Pardo
Social Media And Cognition, Ana C. Ruiz Pardo
Electronic Thesis and Dissertation Repository
Social media is an inescapable platform for sharing media and connecting with others. This thesis investigated how social media impacts cognition; specifically, attention. Study 1 investigated typical social media usage patterns and helped gauge which SM platform was most popular. Study 1 revealed three main platforms people used most often: Facebook, Instagram, and Snapchat. Facebook was reported as the most popular social media platform. Study 2 investigated how a social media post impacts cognition. It was hypothesized that participants who posted, with the intention of provoking a reaction from their followers, on their social media prior to performing a cognitive …
Attentional Preference After A Brief Mindfulness Meditation Intervention, Joshua John Hatherley
Attentional Preference After A Brief Mindfulness Meditation Intervention, Joshua John Hatherley
Electronic Thesis and Dissertation Repository
It has been suggested that as a cognitive exercise, mindfulness meditation has the ability to significantly affect attention in its practitioners. This may help explain why mindfulness meditation has found success in clinical practices. This thesis sought to extend this line of research by investigating the influence of mindfulness meditation on attentional preference. In the context of this paper, attentional preference was seen to be the ability of the viewer to be biased to either detecting local components or the global whole. Study 1 investigated how a 10- minute breathing-oriented mindfulness intervention affects attentional preference on the Navon, Flanker and …
Individual Differences In The Allocation Of Visual Attention During Navigation, Mikayla Keller
Individual Differences In The Allocation Of Visual Attention During Navigation, Mikayla Keller
Electronic Thesis and Dissertation Repository
There are large individual differences in the ability to create an accurate mental representation (i.e., a cognitive map) of a novel environment, yet the factors underlying cognitive map accuracy remain unclear. Given the roles that landmarks and cognitive map accuracy play in successful navigation, the current study examined whether differences in the landmarks that individuals look at while navigating are related to differences in cognitive map accuracy. Participants completed a battery of spatial tests: some that assessed spatial skills prior to a navigation task, and others that tested memory for the environment following exploration of a virtual world. Results indicated …
Transcranial Magnetic Stimulation To Assess Motor System Excitability Fluctuations During Auditory Anticipation And Beat Perception, Johannes G.P Teselink
Transcranial Magnetic Stimulation To Assess Motor System Excitability Fluctuations During Auditory Anticipation And Beat Perception, Johannes G.P Teselink
Undergraduate Honors Theses
Humans tend to spontaneously move to the regular beat of musical rhythm. Beat perception is the tendency to sense and anticipate the regular time positions (beats) that movements synchronize with. The neural motor system plays an important role in beat perception, but the dynamics of excitability in the motor system associated with beat perception have not been characterized. This project investigated motor system excitability fluctuations using transcranial magnetic stimulation and electromyography during perception of beat-based and non-beat-based rhythms. We applied single-pulse TMS over the left primary motor cortex of healthy participants as they listened to three types of rhythms that …
Assessing The Impact Of Emotion In Dual Pathway Models Of Sensory Processing., James H. Kryklywy
Assessing The Impact Of Emotion In Dual Pathway Models Of Sensory Processing., James H. Kryklywy
Electronic Thesis and Dissertation Repository
In our daily environment, we are constantly encountering an endless stream of information which we must be able to sort and prioritize. Some of the features that influence this are the emotional nature of stimuli and the emotional context of events. Emotional information is often given preferential access to neurocognitive resources, including within sensory processing systems. Interestingly, both auditory and visual systems are divided into dual processing streams; a ventral object identity/perception stream and a dorsal object location/action stream. While effects of emotion on the ventral streams are relatively well defined, its effect on dorsal stream processes remains unclear.
The …
Measuring Engagement Of The Executive Control Network From 3 Months Of Age, Michelle Tran
Measuring Engagement Of The Executive Control Network From 3 Months Of Age, Michelle Tran
Electronic Thesis and Dissertation Repository
The executive control network (ECN) is critical for higher cognition and executive function (EF). Despite its importance, no scientific consensus has been reached on how and when it begins to function. In the present study, we assessed the development of the ECN in awake infants less than a year old by employing functional magnetic resonance imaging (fMRI) and naturalistic stimuli. First, we identified evocative movies that engaged infant attention. We then transferred them into adult imaging to test for which movie evoked the highest ECN response. Strong ECN responses were evoked while viewing Despicable Me, therefore we implemented this …
