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. …

An Innocent Bystander Walks Into A Bar: The Influence Of Temporal Proximity And Familiarity On Unconscious Transference, Nia Gipson

Graduate Theses and Dissertations

According to The Innocence Project, 69% of DNA exonerations in the United States involved mistaken eyewitness identification as a contributing factor to these errant convictions. Psychologists have contributed towards minimizing mistaken identifications by proposing best practices that law enforcement still follow today. One understudied cause of mistaken eyewitness identification is unconscious transference (UT). UT is a memory error in which a person encountered in an innocent context becomes confused with a person seen in a guilty context (Loftus, 1976). Past research has established some boundary conditions for when UT can occur; however, the limited methodology has resulted in narrow conclusions …

The Effects Of Interactivity On Memory Relating To Presence In Virtual Environments, Jenny Wong

Psychological Science Undergraduate Honors Theses

The overall effectiveness of virtual environments is often linked to and measured by degrees of presence, commonly defined as the psychological sensation of “being there” (Schubert et al., 1999). Psychologists agree that attention and involvement through interactivity play a role in presence (Hartmann et al., 2015; Schubert et al., 1999; Witmer and Singer, 1998). Because attention is critical in encoding information into memory storage, looking at how memory relates to presence is another topic of interest. In this study, participants (N = 30) played through a 3D virtual reconstruction of a Pompeian house under one of two conditions: free-roam …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

Memory Strategy Instruction With Goal-Setting And Positive Feedback: Impact On Memory, Strategy Use, And Task Commitment, Mercedes E. Ball

University of the Pacific Theses and Dissertations

Strategy instruction can improve memory performance, but some training programs are more effective than others. Some scholars propose that a key element to boosting the benefits from training programs is enhancing or emphasizing self-regulatory factors, such as knowledge about memory, beliefs about ability, or motivational factors. Research supporting this claim evidence adds that programs that enhance trainees’ confidence in their abilities improve memory performance and that multifactorial programs are more effective than strategy-training-only programs. Setting performance goals and receiving feedback are two self-regulatory factors known to relate to memory performance that may sometimes be included in some training programs. However, …

The Role Of A Polyrhythm’S Pitch Interval In Music-Dependent Memory, Hadley R. Parum

Senior Projects Spring 2021

When listening to music, humans can easily and often automatically assess the perceptual similarity of different moments in music. However, it is difficult to rigorously define the way in which we determine exactly how similar we find to moments to be. This problem has driven inquiry in music cognition, musicology, and music theory alike, but previous results have depended on behaviorally mediated responses and/or recursive analytic strategies by music scholars. The present work employs the context-dependent memory paradigm as a novel way to investigate the extent to which listeners consider two musical examples to be similar. After incidentally learning words …

The Internet-Extended Mind: The Psychological Ramifications And Philosophical Implications Of Cognitive Offloading, Gloria Choi

Scripps Senior Theses

In this thesis, I explore the internet-extended mind through both philosophical and psychological lenses in order to investigate the questions “To what extent is the mind extended onto the internet and, more generally, outside our bodies?” and “How will an increasingly internet-extended brain change the ways in which humans communicate, remember, and behave?”. First, I introduce the idea of a mind that extends out into the world, instead of lying solely in the brain. Then, I outline existing research that introduces the challenges and implications of an internet-extended mind in an ever-changing internet landscape. Next, I discuss how the internet …

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …

Modeling Melodic Dictation, David John Baker

LSU Doctoral Dissertations

Melodic dictation is a cognitively demanding process that requires students to hear a melody, then without any access to an external reference, transcribe the melody within a limited time frame. Despite its ubiquity in curricula within School of Music settings, exactly how an individual learns a melody is not well understood. This dissertation aims to fill the gap in the literature between aural skills practitioners and music psychologists in order to reach conclusions that can be applied systematically in pedagogical contexts. In order to do this, I synthesize literature from music theory, music psychology, and music education in order to …

Neurological Correlates Of The Dunning-Kruger Effect, Alana Lauren Muller

Electronic Theses, Projects, and Dissertations

The Dunning-Kruger Effect is a metacognitive phenomenon in which individuals who perform poorly on a task believe they performed well, whereas individuals who performed very well believe their performance was only average. To date, this effect has only been investigated in the context of performance on mathematical, logical, or lexical tasks, but has yet to be explored for its generalizability in episodic memory task performance. We used a novel method to elicit the Dunning-Kruger Effect via a memory test of item and source recognition confidence. Participants studied 4 lists of words and were asked to make a simple decision about …

The Holographic Principle Of Mind And The Evolution Of Consciousness, Germine, Mark

Journal of Conscious Evolution

The Holographic Principle holds the information in any region of space and time exists on the surface of that region. Layers of the holographic, universal “now” go from the inception of the universe to the present. Universal Consciousness is the timeless source of actuality and mentality. Information is experience, and the expansion of the “now” leads to higher and higher orders of experience in the Universe, with various levels of consciousness emerging from experience. The brain consists of a nested hierarchy of surfaces which range from the most elementary field though the neuron, neural group, and the whole brain. Evidence …

Memory Of Words: A Categorization Task, Paulina Maxim

Honors Undergraduate Theses

Through the years, the Deese-Roediger-McDermott Paradigm has demonstrated to be a useful method of observing false memories from semantically related word lists. The present study was conducted fully online and measured memory performance dependent on categorization of words by using groups, as well as dragging words across the page as a form of interaction. In a 2 (Categorized, Non-Categorized) x 2 (Interactive, Non-Interactive) between-subject factorial experiment, 56 undergraduate students were shown 18 different lists of 15 associative words to be studied, one list at a time. Participants were given a free recall test immediately after studying each individual list. Participants …

Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur

Jeffrey Stevens Publications

Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions or with actions from previous …

Eliciting A Perpetrator Description Using The Cognitive Interview: Influences On Investigative Utility, Geri Satin

FIU Electronic Theses and Dissertations

The Cognitive Interview (CI) has been shown in over one hundred studies to enhance eyewitness recall. However, no study has explored whether the CI improves police job performance. The current study was the first to test the practical value of the CI in a criminal investigation, testing participants’ performance on key police tasks using either a perpetrator description elicited from a CI or from a standard police interview (SI).

In an earlier study, student witnesses were exposed to a simulated robbery and were then interviewed using either a CI or an SI to elicit a description of the robber (comprised …

Is Cooperative Memory Special? The Role Of Costly Errors, Context, And Social Network Size When Remembering Cooperative Actions, Jeffrey R. Stevens, Tim Winke

Jeffrey Stevens Publications

Theoretical studies of cooperative behavior have focused on decision strategies, such as tit-for-tat, that depend on remembering a partner’s last choices. Yet, an empirical study by Stevens et al. (2011) demonstrated that human memory may not meet the requirements that needed to use these strategies. When asked to recall the previous behavior of simulated partners in a cooperative memory task, participants performed poorly, making errors in 10–24% of the trials. However, we do not know the extent to which this task taps specialized cognition for cooperation. It may be possible to engage participants in more cooperative, strategic thinking, which may …

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 …

The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore

Graduate Theses and Dissertations

I examined the role of memory and attention in prospective person memory. Prospective person memory involves being on the lookout for a person with the goal of completing some task (i.e., contacting the authorities) upon encountering the person. Success at prospective person memory tasks in lab and field based studies is rather low (i.e., less than 10% of people report encountering the person). In the current study the prospective person memory task involved a simulated search for a missing person. I manipulated attention to the missing person and strategic monitoring, which involves being in retrieval mode and searching for cues. …

Reflections Of The Social Environment In Chimpanzee Memory: Applying Rational Analysis Beyond Humans, Jeffrey R. Stevens, Julian N. Marewski, Lael J. Schooler, Ian C. Gilby

Jeffrey Stevens Publications

In cognitive science, the rational analysis framework allows modelling of how physical and social environments impose information-processing demands onto cognitive systems. In humans, for example, past social contact among individuals predicts their future contact with linear and power functions. These features of the human environment constrain the optimal way to remember information and probably shape how memory records are retained and retrieved. We offer a primer on how biologists can apply rational analysis to study animal behaviour. Using chimpanzees (Pan troglodytes) as a case study, we modelled 19 years of observational data on their social contact patterns. Much …

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 …

A range of international experts with diverse backgrounds, theoretical perspectives, and experimental methods contributed to the Topic. Contributions strongly reflect this diversity, ranging from examining pupil dilation in response to viewing Rembrandt portraits to understanding how caffeine supplementation influences levels of spatial processing. In all cases, the authors …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

Self-Defining Memories, Scripts, And The Life Story: Narrative Identity In Personality And Psychotherapy, Jefferson A. Singer, Pavel Blagov, Meredith Berry, Kathryn M. Oost

Psychology Faculty Publications

An integrative model of narrative identity builds on a dual memory system that draws on episodic memory and a long-term self to generate autobiographical memories. Autobiographical memories related to critical goals in a lifetime period lead to life-story memories, which in turn become self-defining memories when linked to an individual's enduring concerns. Self-defining memories that share repetitive emotion-outcome sequences yield narrative scripts, abstracted templates that filter cognitive-affective processing. The life story is the individual's overarching narrative that provides unity and purpose over the life course. Healthy narrative identity combines memory specificity with adaptive meaning-making to achieve insight and well-being, as …

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 …

Trauma Severity And Defensive Emotion-Regulation Reactions As Predictors Of Forgetting Childhood Trauma, Bette L. Bottoms, Cynthia J. Najdowski, Michelle A. Epstein, Matthew J. Badanek

Psychology Faculty Scholarship

Using a retrospective survey, we studied a sample of 1679 college women to determine whether reports of prior forgetting of sexual abuse, physical abuse, and other traumas could be explained by trauma severity and individual differences in the use of defensive emotion-regulation reactions (i.e., repressive coping, dissociation, and fantasy proneness). Among victims of physical abuse (but not sexual abuse or other types of trauma), those who experienced severe abuse and used defensive reactions were sometimes more likely to report temporary forgetting of abuse, but other times less likely to report forgetting. We also found unanticipated main effects of trauma severity …

On The Functional Equivalence Of Monolinguals And Bilinguals In “Monolingual Mode”: The Bilingual Anticipation Effect In Picture-Word Processing, Paul Amrhein

Department of Psychology Faculty Scholarship and Creative Works

Previous evidence indicates that bilinguals are slowed when an unexpected language switch occurs when they are reading aloud. This anticipation effect was investigated using a picture-word translation task to compare English monolinguals and Spanish-English bilinguals functioning in “monolingual mode.” Monolinguals and half of the bilinguals drew pictures or wrote English words for a picture or English word stimuli; the remaining bilinguals drew pictures or wrote Spanish words for a picture or Spanish word stimuli. Production onset latency was longer in cross-modality translation than within-modality copying, and the increments were equivalent between groups across stimulus and production modalities. Assessed within participants, …
