Pushing It To The Limit: Determining Asian Elephant (Elephas Maximus) Olfactory Sensitivity And Discrimination Through A Behavioral Choice Task, Matthew S. Rudolph

Theses and Dissertations

Elephants have shown remarkable olfactory capabilities. Their sense of smell impacts their foraging choices, behavior, and ultimately, survival. Being able to detect a target odor can allow elephants to locate specific resources, identify threats, and find receptive conspecifics. Previous studies have shown that elephants can consistently detect target odors, but have not identified the limits of this detection. Thus, to investigate the extent of elephants’ odor detection capabilities, we tested Asian elephants in a two-step odor discrimination task. First, we investigated whether elephants could detect odors at varying levels of dilution after a training procedure, and then whether they could …

Primacy And Recency Effects On Position Error In Short-Term Memory Recall, Weerachet Sinlapanuntakul, Kelly Harris, Brittany S. Wesley

Beyond: Undergraduate Research Journal

Position error is the most common error in serial recall of short-term memory, especially when environment, language, or similarity factors are presented. Previous studies demonstrate some support for the serial recall resulting in less error-prone for the first and last positions than the middle positions. This study investigates the accuracy of recalling letters and their positions when given a random sequence with minimal to no external factors. The significant predictors influencing position error were the primacy and recency effects. Participants completed a 20-trial experiment on the CogLab Experimental Control Software, which presented a series of letters one at a time …

Code-Switching Patterns Differentially Shape Cognitive Control: Testing The Predictions Of The Adaptive Control Hypothesis, Giliaine Ng, Hwajin Yang

Research Collection School of Social Sciences

Bilinguals engage in qualitatively different code-switching patterns (alternation, insertion, and congruent lexicalization) to different degrees, according to their engagement in different types of interactional contexts (single-language context, dual-language context, and dense code-switching context). Drawing on the adaptive control hypothesis, we examined whether bilinguals’ code-switching patterns would differentially shape multiple aspects of cognitive control (interference control, salient cue detection, and opportunistic planning). We found that a dense code-switching context, which predominantly involves insertion and congruent lexicalization, was positively associated with verbal opportunistic planning but negatively associated with interference control and salient cue detection. In contrast, a dual-language context, which predominantly involves …

Odors In Cognitive Research: A Commentary On 'Scented Colours' And An Evaluation Study On Odor Quality, With The Example Of Human Wayfinding, Kai Hamburger, Denise Herold

Baltic International Yearbook of Cognition, Logic and Communication

In his target article on “Scented Colours”, Charles Spence highlights the importance of crossmodal connections by focusing on the interaction between odors and colors. In this commentary and our presentation of own empirical work in this research context, we want to reach out further by emphasizing this importance not only on a perceptual and representational level, but also highlight it as an example for spatial cognition research. We provide an evaluation study on emotional effects of odors that could be used in future interdisciplinary research. While the meaning of odors in spatial wayfinding is, thus far, not well investigated, we …

Semantic Network Activation Contributes To The Relationship Between Mood And Inhibition, James S. Maniscalco

Dissertations, Theses, and Capstone Projects

Prior research has identified several relationships between mood and executive functions. Very broadly, these findings generally suggest that positive moods are associated with enhanced cognitive performance, particularly in working memory and learning. However, recent studies note that there are some instances in which negative moods may benefit select executive skills, such as those involved in divided attention and inhibition. In sum, these findings indicate that positive moods favor top-down, heuristic, or relational processing, whereas negative trait moods favor bottom-up, detail-oriented processing. However, a clear mechanism by which these effects occur has yet to be identified.

The most compelling theories that …

A Pilot Study Investigating Adopted Children’S Cultural Identity From Adopting Parents’ Perspective, Alyssa Mcveigh

Symposium of Student Scholars

Adopted children are faced with challenges of identity and a sense of belonging within their adopted family and environments. Research regarding adopted children suggests that their cultural identity is developed by the experiences they have within their biological culture such as, participating in holidays, meeting individuals who are from the same background or visiting their biological country. The goal of this pilot study was to explore the perspectives of adopting parents on their adopted children's cultural identity development, laying a foundation for the next study that will examine adopted children’s (college students) perspective. Ten adopting parents from The United States …

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

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

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

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 …

Book Review: Mythic Imagination Today: The Interpretation Of Mythology And Science By Terry Marks-Tarlow, Ivana Gligoric

Journal of Conscious Evolution

Terry Marks-Tarlow interprets mythology and science as endless curiosity about the workings of the Universe, combing with humans’ creative urges to transform inner and outer worlds. The author perceives mythology as a universal product of the human imagination in interaction with the physical and social world, driven by the urge to communicate with others symbolically and make meaning out of life experiences. Moreover, Marks-Tarlow studied the origins of a human story within the social brain, mythmakers, and myths from multiple cultures. At the same time, she explored how contemporary sciences of chaos, complexity theories, and fractal geometry unite with ancient …

Lgbt Inclusivity In Transpersonal Psychology: A Case For Incorporating Lgbt Spiritual Experiences In Transpersonal Education, Daniel A. Seda, Phd

Journal of Conscious Evolution

After conducting three qualitative interviews on the somatic experiences of transgender individuals and finding relatively few resources with which to draw significant conclusions in the field, it is clear that Lesbian, Gay, Bisexual, and Transgender (LGBT) scholarship is severely lacking in transpersonal psychology.

Method: This research revealed that an understanding and appreciation for the lived experiences of gay people––specifically that of gay men––are also limited and are not appropriately represented through the use of feminist or queer models. Therefore, an alarming number of issues affecting the transgender and gay male populations are not being adequately addressed within the discipline of …

Nondual Writing: A Perspective On Who Owns Ideas, And A Way To Write With Greater Ease, Andrew Erdman

Journal of Conscious Evolution

The act of writing can cause great anxiety, stoking flames of perfectionism and fears of criticism, narcissistic injury, or indifference. While Buddhist teachings provide liberation from such egoic loneliness, it is not often recognized that postmodern and post-structural thought may also put the “author” and their “writing” in a less-individualized context—one in which a written work is understood to be in fact an ongoing process taking shape in interactions among writer, reader, critic, fan, and the world of literature at large. Keeping such a model in mind can help return joy to the act of writing as it poses the …

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 …

Does Working Memory Capacity Modulate The Relationship Between Intentional Mind-Wandering And Task Demand?, Stephen Ware

Electronic Theses, Projects, and Dissertations

Mind wandering (MW) is affected by multiple factors. Among those factors, the present study investigated the effects of working memory capacity on task demands on types of mind wandering. It was hypothesized that individuals with high working memory capacity (WMC) would show more intentional mind wandering in a low demanding task, and in this case, task performance would not be impaired. On the other hand, individuals with low working memory capacity would show more unintentional mind wandering in the high demand condition; therefore, task performance would be affected. Task demand was manipulated with verbal n-back tasks and WMC was measured …

The Effect Of Parent Interactions On Young Infants’ Visual Attention In An Object Manipulation Task., Nonah Marie Olesen

Electronic Theses and Dissertations

The Sticky Mittens (SM) task, an object-manipulation task that facilitates typically developing pre-reaching infants’ learning through active experience with objects, is often utilized to understand how experience affects young infants’ learning about objects. SM experience has been shown to increase infants’ attention to objects, object engagement, and object exploration (Libertus & Needham, 2010; Needham, Barrett, & Peterman, 2002) and facilitates development of causal perception (Rakison & Krogh, 2012; Holt, 2016). Although the majority of SM studies have involved parents interacting naturally with their infants, few have focused on how those interactions affect infants’ learning and performance during or after SM. …

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 …

More Evidence That Magnitude Interference In Temporal Reproduction Results From Memory, Not Clock, Interference, Steven A. Masi

Seton Hall University Dissertations and Theses (ETDs)

Past research has found that errors made when acting on magnitude information is influenced by irrelevant magnitude information that is simultaneously present in the environment. This study investigated the processing stage during which the interference occurs. Each participant completed 80 test trials in stimulus (encoding stimulus) appeared on the computer screen for one of four lengths of time and then disappeared. After which, participants held down the computer spacebar for either the full or half the time that the encoding stimulus was on the screen. In both conditions, a second stimulus (reproduction stimulus) was displayed as the participants held down …

Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz

Graduate Theses and Dissertations

This project expanded on the Acquired Preparedness Model of Risk (APMR) by examining how Negative Urgency (NU), the tendency to act rashly in negative emotional states, affects emotion-based changes in alcohol cognitions to produce risk for alcohol use. The APMR prioritizes the role of outcome expectancies as the means through which traits such as NU, convey alcohol use risk. However, this model treats these cognitions as static and often fails to assess their valence; further, alcohol-cognitions fluctuate in response to negative emotions and may become more salient during these states. Therefore, this study examined: 1) how NU impacts negative emotion-based, …

Combating Conspiracy Theories: An Attitudes-Based Approach, Marie Altgilbers

Graduate Theses and Dissertations

The prevalence of conspiracy theories is a topic of increasing concern among researchers. Much of the research in this area has been focused on why people endorse conspiracy theories, and relatively little attention has been paid to how they may be mitigated. What research has been done focused primarily on interventions with arguments based in cognitive, fact-based appeals, with mixed success. The present research draws on findings from the attitudes and persuasion literature to test the hypothesis that conspiracy theory endorsement is more effectively reduced by affectively-based arguments than by cognitively-based arguments. Two affectively-based interventions were tested against a cognitively-based …

Identity Transformation Through Substance Use Disorder Recovery: Introducing The Six Stage Model, Naomi Watkins, Austin Mcneill Brown, Kayce Courson

The Qualitative Report

Narratives of substance use disorder recovery experience can provide useful qualitative conceptual categories and novel theories about the way in which recovery is experienced by individuals. This information can better inform definitions, concepts, and supports for recovery processes. The current study reviewed 30 written personal recovery biographies which were contained within student applications to the collegiate recovery program housed in the Center for Young Adult Addiction and Recovery at Kennesaw State University. Using grounded theory methodology, common benchmarks, or topographic recovery features were revealed involving the evolution of identity as an inter-negotiated process throughout the addiction and recovery biographies (Charmaz, …

Metacognitive Function In Moderate To Severe Traumatic Brain Injury, Grace Amadon

Honors Theses

Traumatic brain injury (TBI) is an injury to the brain caused by a bump, blow, jolt to the head. Individuals with TBI demonstrate decreased awareness of their own potential deficits and functional abilities. These deficits have critical implications for recovery as self-awareness is important for those recovering from TBI in the implementation and engagement of rehabilitative processes after TBI. The following study analyzed 18 individuals with TBI approximately 11 years post injury to document metacognitive functioning after injury. Participants completed a metacognitive working-memory paradigm where they made judgements of their future and past performance on identifying a target shape and …

The Effect Of Parent Interaction On Pre-Reaching Infants’ Visual Attention During An Object Manipulation Task., Jalena N. Slaton

College of Arts & Sciences Senior Honors Theses

Infants do not begin intentionally reaching for and grasping objects until around 5 months of age. The sticky mittens paradigm (SM) provides infants the opportunity to manipulate and explore objects on their own. Active SM experience has been shown to lead to positive cognitive outcomes (Libertus & Needham, 2010), including facilitating causal perception (Rakison & Krogh, 2012). While some aspects of SM that contribute to positive outcomes are well understood (e.g., active vs. passive experience), the role of parent interactions has received little attention. In this study, SM training was used to investigate the role that parents play in their …

Memory Suppression: The Importance Of Baseline Learning For The Think/No-Think Task, Curtis Rogers

Undergraduate Honors Theses

Studies using the think/no-think task have never addressed the baselines they use throughout the experiment. This study's primary goal was to investigate the effect differing baselines for word-pair learning (50% vs. 75%) would have on the think/no-think task. A replication of Anderson and Greene’s 2001 study using the Think/No-Think task was performed using either a 50% or 75% baseline as a threshold for participants moving to the think/no-think phase of the experiment. Due to the COVID-19 pandemic, this study implemented the think/no-think task online. Recall was evaluated using same and independent-probe memory tests.

Firstly, this study replicated the think/no-think effect …

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 …

Does Anodal Tdcs Over The Left Prefrontal Cortex Using The F3-Rso Montage Improve Cognitive Control?, Sydney Darling

Honors Scholar Theses

Cognitive control is the ability to focus on relevant stimuli while disregarding irrelevant stimuli and is thought to be supported by the prefrontal cortex (see Miller & Cohen, 2001). Transcranial Direct Current Stimulation (tDCS) is a noninvasive brain stimulation technique that modulates the activity of underlying cortex regions through an electric current provided by two or more electrodes on the scalp. This study looks to determine whether anodal tDCS over the left prefrontal cortex can be used to increase cognitive control in healthy participants. Using an F3-RSO montage in a mixed between and within subjects design (with sham vs. anodal …
