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 …

Filled/Non-Filled Pairs: An Empirical Challenge To The Integrated Information Theory Of Consciousness, Amber R. Hopkins, Kelvin J. Mcqueen

Philosophy Faculty Articles and Research

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with relatively high integrated information (Φ) compared to veridical visual perceptions. We then present filled/non-filled pairs as …

Prudence, Ethics And Anticipation In Visionary Leaders, Yanick Farmer

The Journal of Values-Based Leadership

In ethics, prudence is an essential skill in making informed decisions. Although several studies in various fields have dealt with the notion, few empirical studies have addressed one of its inextricable aspects: anticipation. To gain a better understanding of the notion, this study questioned fifteen leaders whose peers consider to be “visionary” in their respective fields. The results of this qualitative study based on semi-structured interviews describe the fundamental aspects of anticipation according to three categories: reasoning and trend analysis, implementation and strategy, and personality and values.

Refugee Children In Malaysia: Perceptions Of Family And Coping Mechanisms, Jin Kuan Kok, Khengkia Khor, Kai Yee Hon, Gertina J. Van Schalkwyk

The Qualitative Report

The percentage of refugee children in Malaysia has been growing in recent years with a rise of more than 9000 in less than 3 years. More than 51,000 of the 164,620 documented refugees in 2019 are below the age of 18 years. Refugee children are often marginalized in society making them vulnerable and requiring special assistance in meeting their educational needs, mental health care and socio-emotional wellbeing. The purpose of this study was to discover the perceptions of refugee children regarding family life and their emotional and coping mechanisms. Employing the Collage Life-Story Elicitation Technique (CLET) and a discovery-oriented narrative …

Growth In Confidence And Search For Belonging: A Case Study Of Muslim Student Experience At An American College, Amir Duric

Muslim Student Life

The broader perception of Muslim Student Association (MSA) in the wider society is not always positive. It is often viewed as a conservative organization where all members need to be a specific type of Muslim to fit in or a political space influenced by a foreign group or ideology. Because of this I studied the group, and my findings challenge this view drawing from the semester-long fieldwork, participant observations, and four in-depth interviews with MSA members at Salt City University (SCU). Data collected shows how the group and its members and the broader Muslim community on campus made Muslim students …

The Understanding Of Digital And Multimedia Evidence (Dme) By Attorneys And Digital Forensic Examiners (Dfe) Within The United States Criminal Justice System, Joseph Levi White

Dissertations

One goal of this research was to determine potential themes that may influence the understanding of Digital and Multimedia Evidence (DME) by attorneys and Digital Forensic Examiners (DFE) within the United States Criminal Justice System. Qualitative semi-structured interviews were conducted to gather information from experienced criminal attorneys and DFEs regarding potential influences on their understanding of DME. The results of these interviews were transcribed, and the data coded to allow for qualitative analysis. Five themes were developed from this data and are thought to play a role in understanding of DME by attorneys and DFEs: motivation for involvement in the …

Facial Expressions And Emotion Labels Are Separate Initiators Of Trait Inferences From The Face, Anthony Stahelski, Amber Anderson, Nicholas Browitt, Mary Radeke

All Faculty Scholarship for the College of the Sciences

Facial inferencing research began with an inadvertent confound. The initial work by Paul Ekman and Wallace Friesen identified the six now-classic facial expressions by the emotion labels chosen by most participants: anger, disgust, fear, happiness, sadness, and surprise. These labels have been used by most of the published facial inference research studies over the last 50 years. However, not all participants in these studies labeled the expressions with the same emotions. For example, that some participants labeled scowling faces as disgusted rather than angry was seen in very early research by Silvan Tomkins and Robert McCarty. Given that the same …

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 …

Future Possibilities For Adults With Autism Spectrum Disorder, Nicolas Leonardi

Capstone Projects and Master's Theses

Autism Spectrum Disorder’s nature of presenting socially awkward behaviors creates barriers for those with ASD in the job interview process. This problem raises questions on how the interview process can be redefined to be more inclusive. Dillenburger et al. conducted a study on interventions provided for individuals with ASD. The study concluded that most jobs do not provide an appropriate job interview process for those with ASD. Solomon et al. and Maras et al. both conducted studies that highlighted the social behaviors presented by individuals with ASD that prevented them from being hired during the job interview process. Both of …

The Relationship Between Cognitive Functioning And Internalizing/Externalizing Behaviors In Children And Adolescents With Down Syndrome, Jessalin R. Good

USC Aiken Psychology Theses

Introduction: Down syndrome (DS) is a developmental disorder caused by a complete extra copy of chromosome 21. This genetic error results in a variety of other symptoms related to a range of medical and cognitive challenges. Although it has been reported that a significant relationship exists between cognitive functioning and both internalizing and externalizing behaviors in typically developing (TD) individuals, the literature is severely limited in investigating this relationship in those with DS.

Rationale: Internalizing and externalizing behaviors have been shown to have a negative relationship with cognitive functioning in TD children and adolescents (Shankman et al., 2010; Wood et …

Boosting Brain Waves Improves Memory, Richard J. Addante, Mairy Yousif, Rosemarie Valencia, Constance Greenwood, Raechel Marino

Psychology Student Publications

Have you ever wanted to improve your memory? Or have you struggled to remember what you studied? Memory uses special patterns of activity in the brain. This experiment tested a new way to create brain wave patterns that help with memory. We wanted to see if we could improve memory by using lights and sounds that teach the brain waves to be in sync. People wore special goggles that made flashes of light and headphones that made beeping noises. This trained the brain through a process called entrainment. The entrainment put the brain in sync at a specific brain wave …

Population-Based Approaches For Monitoring The Nurturing Care Environment For Early Childhood Development: A Scoping Review, Jéssica Pedroso, Stefanie Eugênia Dos Anjos Coelho Kubo, Priscila Olin Silva, Gabriel Ferreira De Castro, Juliana Lopes Pimentel, Rafael Pérez-Escamilla, Muriel Bauermann Gubert, Gabriela Buccini

Social & Behavioral Health Faculty Publications

Selecting indicators to monitor nurturing care (NC) environments that support decision-making and guide the implementation of integrated early childhood development (ECD) programmes has become a priority globally. Several population-based approaches have been attempted to create a set of indicators or a composite index methodology to measure the NC environment using existing secondary data. However, they have not been systematized. Our scoping review aimed to analyse the population-based approaches for monitoring the domains of the NC (e.g. good health, adequate nutrition, responsive caregiving, security and safety, and opportunities for early learning). ECD experts, peer-reviewed, and grey literature were systematically searched with …

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 …

The Benefits Of Spatial Separation On The Cortical Representations Of Speech Sounds, Benjamin H. Zobel

Doctoral Dissertations

Spatial separation between competing speech streams reduces their confusion (informational masking) and improves speech processing under challenging listening conditions. The precise stages of auditory processing and the bottom-up and top-down mechanisms involved in this spatial release from informational masking are not fully understood. Event-related potentials (ERPs) were used to measure the cortical processing of relevant speech under conditions of informational masking and its spatial release, and to examine the preattentive and attentive mechanisms that benefit listeners. Participants were asked to detect noise-vocoded target speech presented with noise-vocoded two-talker masking speech. In separate conditions, the same set of targets were spatially …

Looking For A More Effective Online Learning Experience: Personality And Attention Ability As Moderators, Caroline Smith, Courtney Keim

River Cities Industrial and Organizational Psychology Conference

Historically, organizations have used in-person training, while sometimes relying on technology (e.g., pre-recorded tapes), to train employees. However, online instruction has become the preferred method of educational and organizational learning experiences, exacerbated by the COVID pandemic (Use, 2020). Sometimes online learning produces greater knowledge gain and similar satisfaction to in-person instruction, and other times the learning is equal (cf. Sitzmann, et al., 2006). Despite the assumption that online training is cheaper and easier to deliver, it should be implemented so that the technology allows for effective learning (Salas et al., 2012, emphasis added) and in ways that accommodate disabilities (Use, …

Infant And Child Multisensory Attention Skills: Methods, Measures, And Language Outcomes, Elizabeth V. Edgar

FIU Electronic Theses and Dissertations

Intersensory processing (e.g., matching sights and sounds based on audiovisual synchrony) is thought to be a foundation for more complex developmental outcomes including language. However, the body of research on intersensory processing is characterized by different measures, paradigms, and research questions, making comparisons across studies difficult. Therefore, Manuscript 1 provides a systematic review and synthesis of research on intersensory processing, integrating findings across multiple methods, along with recommendations for future research. This includes a call for a shift in the focus of intersensory processing research from that of assessing average performance of groups of infants, to one assessing individual differences …

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 …

Crowd Salience Heightens Tolerance To Healthy Facial Features, Mitch Brown, Ryan E. Tracy, Steven G. Young, Donald F. Sacco

Publications and Research

Objective: Recent findings suggest crowd salience heightens pathogen-avoidant motives, serving to reduce individuals’ infection risk through interpersonal contact. Such experiences may similarly facilitate the identification, and avoidance, of diseased conspecifics. The current experiment sought to replicate and extend previous crowding research.

Methods: In this experiment, we primed participants at two universities with either a crowding or control experience before having them evaluate faces manipulated to appear healthy or diseased by indicating the degree to which they would want to interact with them.

Results: Crowding-primed participants reported a more heightened preferences for healthy faces than control-primed participants. Additionally, crowd salience reduced …

Resetting Of Auditory And Visual Segregation Occurs After Transient Stimuli Of The Same Modality, Nathan C. Higgins, Ambar G. Monjaras, Breanne D. Yerkes, David F. Little, Jessica E. Nave-Blodgett, Mounya Elhilali, Joel S. Snyder

Psychology Faculty Research

In the presence of a continually changing sensory environment, maintaining stable but flexible awareness is paramount, and requires continual organization of information. Determining which stimulus features belong together, and which are separate is therefore one of the primary tasks of the sensory systems. Unknown is whether there is a global or sensory-specific mechanism that regulates the final perceptual outcome of this streaming process. To test the extent of modality independence in perceptual control, an auditory streaming experiment, and a visual moving-plaid experiment were performed. Both were designed to evoke alternating perception of an integrated or segregated percept. In both experiments, …

The Motion Aftereffect: Mechanisms And Variants, Erica E. Hassoun

The Cardinal Edge

The motion aftereffect causes a visual stimulus to undergo apparent motion. An adapting stimulus, which moves in a specific direction, adapts motion-responsive neurons in the middle temporal area (V5) to that direction of motion. Viewing a second stimulus, a test stimulus, produces apparent motion in the direction opposite that of the initial stimulus. Neural networks involved in attention and working memory are also implicated in the motion aftereffect. There is still little known regarding the mechanisms of the motion aftereffect, despite extensive documentation in the literature. This review discusses established knowledge of the motion aftereffect, focusing primarily on the middle …

During Natural Viewing, Neural Processing Of Visual Targets Continues Throughout Saccades, Atanas D. Stankov, Jonathan Touryan, Stephen Gordon, Anthony J. Ries, Jason Ki, Lucas C. Parra

Publications and Research

Relatively little is known about visual processing during free-viewing visual search in realistic dynamic environments. Free-viewing is characterized by frequent saccades. During saccades, visual processing is thought to be suppressed, yet we know that the presaccadic visual content can modulate postsaccadic processing. To better understand these processes in a realistic setting, we study here saccades and neural responses elicited by the appearance of visual targets in a realistic virtual environment. While subjects were being driven through a 3D virtual town, they were asked to discriminate between targets that appear on the road. Using a system identification approach, we separated overlapping …

A Schema-Theoretic Approach To Hierarchy In Eighteenth-Century Tonality, Simon K. S. Prosser

Dissertations, Theses, and Capstone Projects

Prevalent modern-day theories of tonal hierarchy for eighteenth-century music, especially those influenced by the ideas of Heinrich Schenker, have been called into question by schema theorists such as Robert Gjerdingen and Vasili Byros, who argue from both cognitive and historical evidence that eighteenth-century tonal cognition was sequential or “windowed” rather than hierarchical. This dissertation seeks to recuperate the concept of tonal hierarchy in eighteenth-century music, drawing on research that reconstructs the implicit tonal theories of the partimento and thoroughbass traditions, as well as concepts of hierarchy from schema theory itself, to formulate a historically and cognitively grounded theory of tonal …

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 …
