Usri Summer Experience - Psychological Intern, Jessica Ierullo

Undergraduate Student Research Internships Conference

I had the pleasure of working with Colin King under the Mary J. Wright Child and Youth Development Clinic to aid in their new research project. Studying children, the goal for the project is to assess the psychological impacts that long-term, intensive PCCU care has on the youth. Throughout the summer, I worked as an intern, helping to establish a base from which the project can stem from. This short slide show highlights the current progress that has been made towards setting up the study. I am looking forward to inspecting the study results once it is completed.

Teaching Psychology In V2: To Stream Or Not To Stream, That Is The Question, Andrew L. Vincent Mr.

Undergraduate Student Research Internships Conference

University education has historically occurred in face-to-face settings such as the traditional campus lecture hall. However, university teaching has increasingly been instructed online, especially since the recent lockdowns that took place during the COVID19 pandemic. During the pandemic period, many post-secondary institutions took to online teaching formats which often included asynchronous lessons provided by pre-recorded video or synchronous lessons conducted over video conferencing software. Unfortunately, online courses potentially limit the amount of communication possible between student and professor and therefore the engagement between the two may have been limited. Due to this, concerns have been expressed that students may feel …

Parent-Youth Similarities On Negative Affect: Analyses Of Language Parameters In Semi-Structured Interviews, Leo Ye

Undergraduate Student Research Internships Conference

Abstract

Emotion is a crucial component of verbal communication that conveys messages besides the semantic meanings in speech. The phonological and locutionary cues reflect various emotional effects that are detectable for interpretation. Past research suggests that people who are physically and psychologically close to each other tend to express similar emotions through speech. This relationship has been scrutinized under empirical research for parent-infant relations. However, it is unclear whether the effect exists between parents and youths. This study analyzes recorded speeches of n = 8 parent-youth pairs from semi-structured Zoom interviews and compares them based on their similarities in negative …

But I’M Bad At Math: Students’ Feelings About Math And Intention To Declare A Degree In Psychology, Danielle H. Ward

Brescia Psychology Undergraduate Honours Theses

The current study investigated the association between math anxiety, math self-concept, and math self-efficacy with intention to declare a degree in psychology. Additionally, the study investigated whether knowledge of the statistics requirement in psychology was associated with psychology degree intentions and whether the three math factors were associated with time since last math course. Undergraduate students completed a questionnaire concerning their intention to pursue a psychology degree, the revised version of the Fennema-Sherman Mathematics Anxiety Scale, the Self-Description Questionnaire III Mathematics Subscale, and the Mathematics Self-Efficacy Scale. Results revealed no significant relationships between scores on the three math scales and …

A Mixed-Methods Examination Of Modern Feminist Identity, Jaclyn Siegel

Electronic Thesis and Dissertation Repository

Gender inequality remains a pressing social issue around the world. Due to recent social movements, feminism has become a part of the cultural zeitgeist, and an increasing number of people have begun identifying as feminists in recent years. However, many modern feminists maintain a sense of ambivalence about the movement and their place within it. This ambivalence is difficult to study because the tools designed to evaluate feminist attitudes and identity do not capture this or other important and common aspects of modern feminist identity, such as fear of stigma, solidarity with other feminists, and competence to engage in feminist …

Coordinated Pluralism As A Means To Facilitate Integrative Taxonomies Of Cognition, Jacqueline Anne Sullivan

Brain and Mind Institute Researchers' Publications

© 2017 Informa UK Limited, trading as Taylor & Francis Group. The past decade has witnessed a growing awareness of conceptual and methodological hurdles within psychology and neuroscience that must be addressed for taxonomic and explanatory progress in understanding psychological functions to be possible. In this paper, I evaluate several recent knowledge-building initiatives aimed at overcoming these obstacles. I argue that while each initiative offers important insights about how to facilitate taxonomic and explanatory progress in psychology and neuroscience, only a “coordinated pluralism” that incorporates positive aspects of each initiative will have the potential for success.

Effects Of A Consistent Target Or Masker Voice On Target Speech Intelligibility In Two- And Three-Talker Mixtures., Fabienne Samson, Ingrid S Johnsrude

Brain and Mind Institute Researchers' Publications

When the spatial location or identity of a sound is held constant, it is not masked as effectively by competing sounds. This suggests that experience with a particular voice over time might facilitate perceptual organization in multitalker environments. The current study examines whether listeners benefit from experience with a voice only when it is the target, or also when it is a masker, using diotic presentation and a closed-set task (coordinate response measure). A reliable interaction was observed such that, in two-talker mixtures, consistency of masker or target voice over 3-7 trials significantly benefited target recognition performance, whereas in three-talker …

Neurogenesis-Mediated Forgetting Minimizes Proactive Interference., Jonathan R Epp, Rudy Silva Mera, Stefan Köhler, Sheena A Josselyn, Paul W Frankland

Brain and Mind Institute Researchers' Publications

Established memories may interfere with the encoding of new memories, particularly when existing and new memories overlap in content. By manipulating levels of hippocampal neurogenesis, here we show that neurogenesis regulates this form of proactive interference. Increasing hippocampal neurogenesis weakens existing memories and, in doing so, facilitates the encoding of new, conflicting (but not non-conflicting) information in mice. Conversely, decreasing neurogenesis stabilizes existing memories, and impedes the encoding of new, conflicting information. These results suggest that reduced proactive interference is an adaptive benefit of neurogenesis-induced forgetting.

Functional Differences Between Statistical Learning With And Without Explicit Training., Laura J Batterink, Paul J Reber, Ken A Paller

Brain and Mind Institute Researchers' Publications

Humans are capable of rapidly extracting regularities from environmental input, a process known as statistical learning. This type of learning typically occurs automatically, through passive exposure to environmental input. The presumed function of statistical learning is to optimize processing, allowing the brain to more accurately predict and prepare for incoming input. In this study, we ask whether the function of statistical learning may be enhanced through supplementary explicit training, in which underlying regularities are explicitly taught rather than simply abstracted through exposure. Learners were randomly assigned either to an explicit group or an implicit group. All learners were exposed to …

Attachment And Attention: An Investigation Of Biases In Attention As They Relate To Attachment Security In Infancy And Adulthood, Paul J. Meinz

Electronic Thesis and Dissertation Repository

At the advent of attachment theory, John Bowlby hypothesized that cognition and emotion are shaped by early experiences with primary caregivers (Bowlby, 1980). This idea – that aspects of cognition may be organized within early relationships – still plays a prominent role in contemporary attachment theory. The studies described within this dissertation provide support for the idea that attachment security in infancy and adulthood are associated with differences in cognition – particularly with differences in the way that people attend to certain forms of stimuli. Mothers and children in the studies described here were first assessed for individual differences in …

Erps Reveal The Temporal Dynamics Of Auditory Word Recognition In Specific Language Impairment., Jeffrey G Malins, Amy S Desroches, Erin K Robertson, Randy Lynn Newman, Lisa M D Archibald, Marc F Joanisse

Brain and Mind Institute Researchers' Publications

We used event-related potentials (ERPs) to compare auditory word recognition in children with specific language impairment (SLI group; N=14) to a group of typically developing children (TD group; N=14). Subjects were presented with pictures of items and heard auditory words that either matched or mismatched the pictures. Mismatches overlapped expected words in word-onset (cohort mismatches; see: DOLL, hear: dog), rhyme (CONE -bone), or were unrelated (SHELL -mug). In match trials, the SLI group showed a different pattern of N100 responses to auditory stimuli compared to the TD group, indicative of early auditory processing differences in SLI. However, the phonological mapping …

The Human Brain Processes Syntax In The Absence Of Conscious Awareness., Laura Batterink, Helen J Neville

Brain and Mind Institute Researchers' Publications

Syntax is the core computational component of language. A longstanding idea about syntactic processing is that it is generally not available to conscious access, operating autonomously and automatically. However, there is little direct neurocognitive evidence on this issue. By measuring event-related potentials while human observers performed a novel cross-modal distraction task, we demonstrated that syntactic violations that were not consciously detected nonetheless produced a characteristic early neural response pattern, and also significantly delayed reaction times to a concurrent task. This early neural response was distinct from later neural activity that was observed only to syntactic violations that were consciously detected. …

Distinct Patterns Of Functional And Effective Connectivity Between Perirhinal Cortex And Other Cortical Regions In Recognition Memory And Perceptual Discrimination., Edward B O'Neil, Andrea B Protzner, Cornelia Mccormick, D Adam Mclean, Jordan Poppenk, Anthony D Cate, Stefan Köhler

Brain and Mind Institute Researchers' Publications

Traditionally, the medial temporal lobe (MTL) is thought to be dedicated to declarative memory. Recent evidence challenges this view, suggesting that perirhinal cortex (PrC), which interfaces the MTL with the ventral visual pathway, supports highly integrated object representations in recognition memory and perceptual discrimination. Even with comparable representational demands, perceptual and memory tasks differ in numerous task demands and the subjective experience they evoke. Here, we tested whether such differences are reflected in distinct patterns of connectivity between PrC and other cortical regions, including differential involvement of prefrontal control processes. We examined functional magnetic resonance imaging data for closely matched …

Discriminating Famous From Fictional Names Based On Lifetime Experience: Evidence In Support Of A Signal-Detection Model Based On Finite Mixture Distributions., Ben Bowles, Iain M Harlow, Melissa M Meeking, Stefan Köhler

Brain and Mind Institute Researchers' Publications

It is widely accepted that signal-detection mechanisms contribute to item-recognition memory decisions that involve discriminations between targets and lures based on a controlled laboratory study episode. Here, the authors employed mathematical modeling of receiver operating characteristics (ROC) to determine whether and how a signal-detection mechanism contributes to discriminations between moderately famous and fictional names based on lifetime experience. Unique to fame judgments is a lack of control over participants' previous exposure to the stimuli deemed "targets" by the experimenter; specifically, if they pertain to moderately famous individuals, participants may have had no prior exposure to a substantial proportion of the …

Perirhinal Cortex Contributes To Accuracy In Recognition Memory And Perceptual Discriminations., Edward B O'Neil, Anthony D Cate, Stefan Köhler

Brain and Mind Institute Researchers' Publications

The prevailing view of the medial temporal lobe (MTL) holds that its structures are dedicated to long-term declarative memory. Recent evidence challenges this position, suggesting that perirhinal cortex (PRc) in the MTL may also play a role in perceptual discriminations of stimuli with substantial visual feature overlap. Relevant neuropsychological findings in humans have been inconclusive, likely because studies have relied on patients with large and variable MTL lesions. Here, we conducted a functional magnetic resonance imaging study in healthy individuals to determine whether PRc shows a performance-related involvement in perceptual oddball judgments that is comparable to its established role in …

Paradoxical Facilitation Of Object Recognition Memory After Infusion Of Scopolamine Into Perirhinal Cortex: Implications For Cholinergic System Function., Boyer D Winters, Lisa M Saksida, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

The cholinergic system has long been implicated in learning and memory, yet its specific function remains unclear. In the present study, we investigated the role of cortical acetylcholine in a rodent model of declarative memory by infusing the cholinergic muscarinic receptor antagonist scopolamine into the rat perirhinal cortex during different stages (encoding, storage/consolidation, and retrieval) of the spontaneous object recognition task. Presample infusions of scopolamine significantly impaired object recognition compared with performance of the same group of rats on saline trials; this result is consistent with previous reports supporting a role for perirhinal acetylcholine in object information acquisition. Scopolamine infusions …

Glutamate Receptors In Perirhinal Cortex Mediate Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Object recognition is consistently impaired in human amnesia and animal models thereof. Results from subjects with permanent brain damage have revealed the importance of the perirhinal cortex to object recognition memory. Here, we report evidence from rats for interdependent but distinct stages in object recognition memory (encoding, retrieval, and consolidation), which require glutamate receptor activity within perirhinal cortex. Transient blockade of AMPA receptor-mediated synaptic transmission within perirhinal cortex disrupted encoding for short- and long-term memory as well as retrieval and consolidation. In contrast, transient NMDA receptor blockade during encoding affected only long-term object recognition memory; NMDA receptor activity was also …

Transient Inactivation Of Perirhinal Cortex Disrupts Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Damage to perirhinal cortex (PRh) impairs object recognition memory in humans, monkeys, and rats when tested in tasks such as delayed nonmatching to sample, visual paired comparison, and its rodent analog, the spontaneous object recognition task. In the present study, we have capitalized on the discrete one-trial nature of the spontaneous object recognition task to investigate the role of PRh in several distinct stages of object recognition memory. In a series of experiments, transient inactivation of PRh was accomplished with bilateral infusions of lidocaine directly into PRh immediately before the sample phase (encoding), immediately before the choice phase (retrieval), or …
