The Effects Of Nonverbal Communication In Online Learning Formats, Hannah Paraiso

Brescia Psychology Undergraduate Honours Theses

This study experimentally investigated the effects of nonverbal communication in online learning formats, and whether there was an impact on working memory. Participants (N = 40) were randomly assigned to watch 1 of 3 different online video formats. Each video had identical slide show and audio content, but different visibility of the speaker. All videos were 10 minutes long and followed by a 15 multiple choice questionnaire based on the video content. Following the experiment, participants also completed demographic questions to obtain data on prior online learning experience, age, and undergraduate years. Results of this study indicated that there was …

An Examination Of The Relation Between Memory Self-Efficacy And Working Memory Within The Cognitive Reserve Framework, Genna Marie Mashinchi Ma

Graduate Student Theses, Dissertations, & Professional Papers

Dementia has been found to negatively affect multiple aspects of cognitive functioning. Despite an increasing prevalence of cognitive decline, many aging adults do not experience reduced cognitive functioning. The reason as to why some experience cognitive decline and others do not is still unclear. One leading theory thought to explain this phenomenon is the cognitive reserve theory (CR), which proposes that certain lifestyle factors (e.g., educational attainment, occupational attainment, and leisure activity participation) prolong one’s cognitive functioning and reduce the risk of cognitive decline. Memory self-efficacy (MSE), defined as one’s beliefs in their memory ability, was found to be positively …

The Relationship Between Auditory Working Memory And Statistical Learning In Infancy, Mckenzie Mullins Sheets

Masters Theses

Although previous research indicates that there is a strong relationship between auditory working memory and language skills in children and adults, no studies have explored this relationship in infancy. Working memory develops shortly before the onset of many language abilities in infancy, including the ability to use statistical information to segment words from speech. To track frequent syllable co-occurrences within a speech stream to locate word boundaries, infants must hold auditory information in their mind as one syllable quickly displaces another. Thus, it seems likely that auditory working memory plays a role in statistical learning. In the current study, I …

Relationship Between Contentment And Working Memory Capacity: Experimental And Naturalistic Evidence, Khai Qing Chua, Rachel Ng, Clarissa L. Q. Sung, Andree Hartanto, Vincent Y. S. Oh, Eddie M. W. Tong

Research Collection School of Social Sciences

Contentment is a positive emotion characterized by perceived goal attainment, a sense of having or being enough, and a focus on the present. Research on this new construct is thin, and no studies have examined its cognitive properties, particularly whether it facilitates or impairs controlled cognitive processes. We hypothesize that contentment positively predicts working memory. We found support for this hypothesis in two experimental studies (Studies 1 and 2) which showed that induced contentment improved working memory in the operation span task, and in one non-experimental study (Study 3) which showed that measured contentment positively correlated with working memory on …

Occupational Therapist Perceptions On How Eye Movement Therapy Supports Working Memory In Children Diagnosed With Attention Deficit/Hyperactivity Disorder, Latres M. Bell

Doctoral Dissertations and Projects

Previous research reports that children with attention-deficit/hyperactivity disorder (ADHD) show a deficit in their working memory. Working memory is the ability to temporarily manipulate, store, and retrieve information during cognitive tasks. Working memory is considered a critical deficiency in individuals diagnosed with ADHD. Working memory has been shown to be a mechanism for symptoms of disorganization and inattention in individuals diagnosed with ADHD. This qualitative research study reviewed occupational therapists’ perceptions on their role working with children, aged six to 10 years old, diagnosed with ADHD and low working memory, who have had eye movement therapy. The occupational therapists’ perceptions …

Understanding The Relationship Between Working Memory And Long-Term Memory, Kelly Cotton

Dissertations, Theses, and Capstone Projects

How lasting memories are created is a question that has driven much research into human cognition. An area of renewed research interest concerns the relationship between working memory and long-term memory. Recent research has investigated how the processing that occurs while information is held in working memory influences successful long-term memory creation. Both working memory consolidation and maintenance have been identified as critical in long-term retention, but the mechanisms underlying the working memory/long-term memory relationship remain unclear. The present dissertation examined different working memory mechanisms and their impact on long-term memory in a broader context by addressing two questions: 1) …

The Role Of Attention Control In Automation Performance, Claire Textor

All Dissertations

Research in human-automation interaction has demonstrated that some individuals are more severely impacted by the negative effects of unreliable automation (i.e., exhibit lower performance) than others. A body of work has sought to explain this variability through individual differences, primarily investigating the role of working memory. However, not all studies have demonstrated a clear relationship between working memory capabilities and performance when using automation. Engle’s (2002) controlled attention theory of working memory posits that the relationship between working memory and other cognitive constructs such as fluid intelligence can be explained through a shared reliance on attention control. Studying the role …

Impact Of Students' Off-Task Technology Use During Instruction On Teachers, David Lancaster

Masters Theses & Specialist Projects

The increase of technology in educational classrooms has changed the way instruction is delivered and received, positively and negatively. When technology is used for off-task purposes, negative effects on student learning are well-documented. However, little research has been conducted on the effect of student off-task technology use on teachers. The purpose of this study was to examine the impact of off-task technology use during instruction on K-12 teachers, while including more modern devices. Two hundred sixty-two Kentucky K-12 teachers completed online surveys in which their perceptions of multitasking, views of the impact of off-task technology use on students, and on …

Working Memory Performance: Is Subjective Measurement A Better Predictor Than Cognitive Load?, Megan Mccray

Dissertations and Theses

We rely on our capacity for rapid attention switching to conduct multiple tasks simultaneously. Leading working memory models assume that memory maintenance and attention-demanding secondary task processing cannot coincide. Any reduction in memory maintenance activities occurring due to secondary task processing leads to impaired recall. This temporal relationship is typically characterized through the proportion of time spent attending to the concurrent processing task, also called cognitive load. Although the primary determinant of forgetting in leading models, recent findings show limitations to cognitive load effects in multitasking. We investigated whether the effects of cognitive load are a byproduct of subjective task …

Longitudinal Effects Of Prenatal Teratogen Exposure On Executive Function And Academic Outcomes, Dawn Michele Moore

CGU Theses & Dissertations

The healthy development of executive function in adolescents is essential for controlling attention and behavior, especially as children confront the challenges associated with puberty, social situations, parental pressures, academic pursuits, and the transition to adulthood. For children prenatally exposed to teratogenic substances (i.e., certain prescription medications, maternal infections or conditions, alcohol, tobacco, etc.), higher-order cognitive skills may be compromised, resulting in an increased risk of delayed developmental functioning, deficits in cognitive and executive functioning, and poorer academic outcomes. Research findings suggest that even low-to-moderate levels of alcohol and/or tobacco use during pregnancy are associated with poorer academic performance, lower IQ …

The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales

CGU Theses & Dissertations

Beginning in the 1970s, a great deal of research in cognitive psychology, developmental psychology, psychometrics, and cognitive neuroscience has investigated the structure and function of working memory (WM), defined as the ability to actively maintain and manipulate information in the service of complex cognition (Baddeley & Hitch, 1974). It is well established that WM is a limited capacity system and individual differences in WM capacity are strongly associated with important cognitive abilities and outcomes, such as general intelligence (Engle et al., 1999) and academic achievement (Swanson & Berninger, 1996; Ramirez et al., 2013). For this reason, WM is a central …

Attention, Working Memory, And Adaptive Functioning In Emerging Young Adults With Psychometrically-Defined Schizotypy, Parth Nakirikanti

Honors Undergraduate Theses

Schizotypy, a complex construct linked to schizophrenia-related traits, encompasses positive, negative, and disorganized symptoms. This study offers a review of the concept of schizotypy, including its historical evolution, tracing it from Bleuler's early mention in 1911 to Meehl's continuum model. Embracing a dimensional perspective, this research underscores the interplay of biological, psychological, and social factors in understanding schizotypy. Deficits in sustained attention and working memory within schizotypy remain underexplored, with prior studies yielding inconsistent results. Adaptive functioning deficits in individuals with schizotypy are also inadequately understood. Examining a college student population, this investigation utilized scores on the Schizotypal Personality Questionnaire …

Are We Ovary-Acting? All Visuospatial Abilities May Not Be Equally Affected Throughout The Menstrual Cycle., Caroline G. Haynes, Audrey N. Wade

Science University Research Symposium (SURS)

Are we ovary-acting? All visuospatial abilities may not be equally affected throughout the menstrual cycle.

Department of Psychological Sciences & Neuroscience, Belmont University, Nashville, TN

Visuospatial skills pertain to the ability to conceptualize and comprehend visual representations of objects and the spatial relationships among objects. They are integral for the proper functioning of other cognitive systems such as memory, attention, and reasoning (Kaufman, 2007). Sex hormones are one of many factors reported to affect visuospatial processing, with estrogen specially being associated with poor performance on visuospatial tasks in females (Hausmann, 2000). The current study investigated performance differences on three visuospatial …

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 …

Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo

Theses

Research on Social Networking Sites (SNS) has shown a variety of both beneficial and detrimental psychological and cognitive outcomes associated with high frequency usage. We conducted an online study consisting of a series of questionnaires and a working memory task to explore the relationship between Instagram use intensity and cognition. The present study first investigated the relationship between Instagram (IG) use intensity, rumination, and cognitive failures. We randomly assigned participants into a selfie-posting, selfie-sending, or likes/comments reporting condition to determine whether selfie-posting behavior affects working memory performance. While we did not find significant associations between IG use intensity, rumination, and …

Evaluating The Effects Of Mindfulness Practice On Attentional Control And Episodic Memory, Jacob M. M. Namias

Master's Theses

Mindfulness refers to a mental state of being that involves nonjudgmental acceptance of current cognitions and emotions with awareness of the present moment. Researchers and clinicians have shown the efficacy of mindfulness as a treatment for psychological disorders such as anxiety and depression and have found reductions in reported stress. Building on clinical benefits, mindfulness practice may also facilitate attentional processes as practitioners are required to inhibit distracting thoughts and re-direct their focus to the present moment. My thesis examined the relationship between mindfulness practice and attentional control and potential spillovers to episodic memory. Experiment 1 gauged the relationship between …

How Do We Represent Possibilities In The Visual World? — An Analysis Of Amodal Completion Under Cognitive And Perceptual Load., Camden Parker

Dartmouth College Undergraduate Theses

How do cognitive and perceptual load affect the way we experience the world when the visual scene is incomplete or partially occluded? The present study seeks to answer this question with a series of experiments based on primed matching, amodal completion, and load theory. In Experiment 1, we replicated results that amodal completion is automatic and supports multiple possible completions. In Experiment 2, we found that working memory load decreases the priming effects of both partially occluded and fully visible shapes. In Experiment 3, we found that perceptual load decreases the priming effect of partially occluded shapes more so than …

Cognitive Task Enhancement Through Alpha Neurofeedback, Hannah L. Meyer, Douglas Peterson

Honors Thesis

Neurofeedback training has been a recent field of study in neuroscience, as a potential way to increase focus, and possibly boost cognitive performance. Most studies utilize a course of neurofeedback training sessions to find positive results in decreasing ADHD symptoms, depression symptoms, as well as further cognitive changes. In this study, we aim to determine the efficacy of a single session of neurofeedback training in increasing cognitive performance. To do so, we randomly separated 42 volunteers into either a control or experimental group. The experimental group participated in an n-back task both before and after an alpha neurofeedback training session, …

The Motivational Role Of Feedback On Working Memory, Danielle Wilson

Theses and Dissertations

Previous research has shown that motivation plays a vital role in what we remember. Motivation can be either extrinsic (e.g., a reward for doing well) or intrinsic (e.g., wanting to do well). Here we test if intrinsic motivation improves Working Memory (WM) performance. In an online study, undergraduate students (N=358, 334 after excluding participants that did not complete at least 25% of the survey) completed reverse letter span tasks, recalling 42 sets of 4-9 letters that were shown for one second in reverse order. We manipulate intrinsic motivation via feedback. Participants were randomly assigned to feedback (FB) and no-feedback (NFB) …

An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios

Electronic Theses and Dissertations

Sport-specific practice of movement techniques is undoubtedly important in young athletes' sport performance. However, in sports that are more heavily reliant on open skills, cognitive factors, such as working memory (WM), attention, and spatial awareness, are more likely to become a barrier for proficiency than form or physical prowess. Nevertheless, the intricacies of the relationships that exist between these cognitive factors has gone relatively unexplored, particularly in the context of sport. The present research explored the impact of sport-specific experience on measures of WM, attentional control, and spatial awareness, and their interactions, through the lens of athletic expertise. Participants consisted …

The Role Of Working Memory In Fraction Arithmetic: Eye Movements During A Dual Task, Krystal Kamekona-Mendoza

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fractions are first introduced at the elementary school age, yet difficulty with fraction computation (i.e., adding, subtracting, multiplying, and dividing) continues to persist throughout adulthood. Research suggests that fraction knowledge is predictive of future math achievement and success in algebra. Given the early age at which this concept is introduced and the critical role that it plays in future mathematics success, it is important to better understand the cognitive mechanisms involved in fraction computation and why students continue to struggle with this concept. The role of executive function (e.g., attention, inhibition, working memory) in fraction arithmetic is complex. While working …

To Switch Or Not To Switch: Individual Differences In Executive Function And Emotion Regulation Flexibility, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Emotion regulation (ER) constitutes strategies that modulate the experience and expression of emotions. While past work has predominantly focused on each ER strategy independently, recent research has begun to examine individual-difference factors that are associated with the flexible implementation of ER strategies in line with environmental demands (i.e., ER flexibility). Considering that ER processes generally implicate executive function (EF)—a collection of adaptive, general-purpose control processes—it is plausible that EF could be involved in ER flexibility. Using a latent-variable approach based on a comprehensive battery of EF tasks, the present study investigated how the various aspects of EF (i.e., common EF, …

The Role Of Selection History In Low-Prevalence Visual Search, Kendra Chamlee Smith

Arts & Sciences Electronic Theses and Dissertations

The low prevalence effect (LPE), the tendency for observers to be more likely to miss rare targets than frequent targets, is a robust error and is difficult to reduce. The LPE is an obstacle in a variety of real-world search tasks in which targets are rare, including baggage screening and some medical imaging. The LPE is thought to occur because when an observer searches for a low-prevalence target, over time, the observer may become both more willing to indicate a target is not there and more likely to end the search early. The present experiments employ three selection history effects, …

Blood Phenylalanine Trajectory And Executive Function Outcomes In Individuals With Phenylketonuria, Clarissa Tardiff

Arts & Sciences Electronic Theses and Dissertations

Phenylketonuria (PKU) is an autosomal recessive disorder characterized by mutations in phenylalanine hydroxylase genes. As a result, phenylalanine (Phe) metabolism is disrupted, and this amino acid accumulates in blood and tissue (Pietz, 1998; Scriver et al., 2000). Although the most severe symptoms of PKU may be avoided by early detection and treatment, many individuals with early-treated PKU still experience difficulties in executive function, attention, and processing speed (Antenor-Dorsey et al., 2013; Araujo et al., 2013; Christ et al., 2020; Hawks, Strube, Johnson, Grange, & White, 2018; Hood, Grange, Christ, Steiner, & White, 2014; Janos et al., 2012; White et al., …

Authentication Schemes' Impact On Working Memory, Janine D. Mator

Psychology Theses & Dissertations

Authentication is the process by which a computing system validates a user’s identity. Although this process is necessary for system security, users view authentication as a frequent disruption to their primary tasks. During this disruption, primary task information must be actively maintained in working memory. As a result, primary task information stored in working memory is at risk of being lost or corrupted while users authenticate. For over two decades, researchers have focused on developing more memorable passwords by replacing alphanumeric text with visual graphics (Biddle et al., 2012). However, very little attention has been given to the impact authentication …

Does Rehearsal Matter? Left Anterior Temporal Alpha And Theta Band Changes Correlate With The Beneficial Effects Of Rehearsal On Working Memory, Chelsea Reichert Plaska, Kenneth Ng, Timothy M. Ellmore

Publications and Research

Rehearsal during working memory (WM) maintenance is assumed to facilitate retrieval. Less is known about how rehearsal modulates WM delay activity. In the present study, 44 participants completed a Sternberg Task with either intact novel scenes or phase-scrambled scenes, which had similar color and spatial frequency but lacked semantic content. During the rehearsal condition participants generated a descriptive label during encoding and covertly rehearsed during the delay period. During the suppression condition participants did not generate a label during encoding and suppressed (repeated “the”) during the delay period. This was easy in the former (novel scenes) but more difficult in …

The Effects Of Emotional Working Memory Training On Trait Anxiety, Gabrielle C. Veloso, Welison Evenston G. Ty

Psychology Department Faculty Publications

Background: Trait anxiety is a pervasive tendency to attend to and experience fears and worries to a disproportionate degree, across various situations. Decreased vulnerability to trait anxiety has been linked to having higher working memory capacity and better emotion regulation; however, the relationship between these factors has not been well-established.

Objective: This study sought to determine if participants who undergo emotional working memory training will have significantly lower trait anxiety post-training. The study also sought to determine if emotion regulation mediated the relationship between working memory training and trait anxiety.

Method: An experimental group comprising of 49 participants underwent 20 …
