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 …

Loneliness, Sense Of Control, And Risk Of Dementia In Healthy Older Adults: A Moderated Mediation Analysis, Hwajin Yang, Germaine Tng, Wee Qin Ng, Sujin Yang

Research Collection School of Social Sciences

Objectives: Despite the rising prevalence of dementia, little research has been conducted to identify modifiable psychological factors that alleviate the risk of dementia in older adults and the underlying mechanisms. Given that loneliness is, in part, concomitant with a weakened sense of control, we examined whether sense of control would mediate the relation between loneliness and dementia risk. Further, considering that working -memory capacity is a critical cognitive resource that serves as a buffer against age-related cognitive decline, we examined a second-order moderated mediational model whereby working-memory capacity moderates the relation between control beliefs and dementia risk in older adults. …

Using Chess As An Intervention To Improve Executive Functioning Among Youth, Anandita Oberoi

Walden Dissertations and Doctoral Studies

Youth represent a vulnerable segment of the population and may have underdeveloped levels of executive functioning (EF), which is important in both daily life and is shown to have far-reaching effects. This research study aimed to decipher if lessons in the game of chess could be used as an efficacious intervention for accelerating EF development in youth. The three research questions focused on determining whether there was a difference in the chosen indices of EF before and after a 14-session chess intervention. The theoretical framework used for this study was Piaget’s cognitive development theory. This quantitative, single group pretest–posttest design …

Using Deep Learning-Based Framework For Child Speech Emotion Recognition, Gerald N. Onwujekwe

Theses and Dissertations

Biological languages of the body through which human emotion can be detected abound including heart rate, facial expressions, movement of the eyelids and dilation of the eyes, body postures, skin conductance, and even the speech we make. Speech emotion recognition research started some three decades ago, and the popular Interspeech Emotion Challenge has helped to propagate this research area. However, most speech recognition research is focused on adults and there is very little research on child speech. This dissertation is a description of the development and evaluation of a child speech emotion recognition framework. The higher-level components of the framework …

A Fidelity-Based Integration Model For Explicit And Implicit Ensemble Coding, Ke Tong

USF Tampa Graduate Theses and Dissertations

Human observers benefit from encoding summary statistical information from multiple similar stimuli, also known as ensemble coding. Empirical studies on ensemble coding have adopted paradigms with vastly different task requirements, raising questions about ensemble coding’s underlying mechanisms in different tasks. Are ensemble coding mechanisms task-dependent? How to model ensemble coding in different tasks? The current paper aims to answer these questions by systematically reviewing the ensemble coding tasks and models and proposing a computational model framework of ensemble coding in different tasks. The task review categorizes the tasks into two main types: Summary tasks (explicitly require observers to summarize ensemble …

Moderation Of Effects Of Anxiety On Verbal And Visuospatial Short-Term Memory In Young Children With Autism Spectrum Disorder, Rachael Arowolo

Clinical Psychology Dissertations

Children with autism spectrum disorder (ASD) exhibit developmental differences in a number of domains, including memory. Short-term memory (STM) has been studied in children with ASD but the findings have been mixed. Children with ASD are also at increased risk of developing an anxiety disorder. Anxiety has been found to impact short-term (STM) and other cognitive functions in typically developing children. Limited research suggests that trait anxiety is associated with poorer STM in school-aged children with ASD. Given that STM develops throughout early childhood, understanding the impact of anxiety in younger children with ASD may be beneficial in providing the …

Exploring The Effects Of Response Type In A Visual Working Memory Task: An Fnirs Study, Rachel Eddings

Masters Theses

Visual working memory (VWM) allows us to hold visual information in mind to be manipulated for a task. Previous research shows that performance varies based on factors such as stimulus modality and number of distractors. This study aimed to explore the effect of response type on VWM performance in 4.5- and 5.5-year-olds. A single-item probe color change detection task and a cued recall with labeling task were administered. The tasks were identical in structure until the response phase of the trial. Neural data were collected using functional near-infrared spectroscopy. Both tasks used set-sizes 1-3 and six canonical colors (red, orange, …

Comparing Verbal And Spatial Working Memory In Monolingual And Bilingual Speakers, Rosaury Hernandez

Theses and Dissertations

The bilingual advantage has been demonstrated in different domains of cognitive functioning, especially executive functioning. Compared to other domains of executive functioning, the impact of bilingualism on working memory in children and adults has received relatively little attention. Moreover, research on the bilingual advantage in young adults has produced mix results in tasks where working memory is required. The present study examined whether bilingual expertise yielded different results depending on the working memory task. The present study included 54 participants, 44 identified as female and 10 identified as male. Spatial working memory was measured using the computerized spatial span task …

Consistent Failure To Produce A Cognitive Load Effect In Visual Working Memory Using A Standard Dual-Task Procedure, Timothy J. Ricker, Evie Vergauwe

Publications and Research

Working memory performance is impaired when an attention-demanding task is executed during memory retention. The cognitive load effect is the consistent finding that the size of the memory impairment is determined by the relative amount of time that the secondary processing task occupies attention during memory retention. Cognitive load has been proposed to be a Priority-A benchmark any model of working memory should be able to explain (Oberauer et al., 2018), in part because the effect appears to generalize across different experimental procedures and materials. Using a standard dual-task procedure, we detail four experiments using a visual working memory recall …

Remember That Party Last Night? Examining The Effects Of Binge-Like Alcohol On Memory, Anna Thomas

Undergraduate Honors Thesis Collection

Alcohol is a widely available drug that is often abused. Studies have shown alcohol-induced memory loss in humans and animals; however, the large amount of alcohol often necessary to observe such loss and use of involuntary drinking paradigms in animals makes translation difficult. The current study was designed to look at voluntary binge-like drinking behavior and memory in rodents. We anticipated decreases in working memory function following consumption of binge-like alcohol in mice and expected a greater deficit in mice experiencing acute withdrawal during the memory task. The present study explored drinking behaviors in adult C57BL/6J mice (18 male, 18 …

Ptsd And Immunological Correlations Of Attention And Working Memory In Gulf War Illness, Mary Jeffrey

Theses and Dissertations

Gulf War Illness (GWI) impacts 25 to 32 percent of those deployed in the 1991 Gulf War (White et al., 2016) and includes symptoms related to fatigue and mood/neurological disturbances. Therefore, it is difficult to ascertain the influence of trauma exposure and chemical exposure when investigating neuropsychological symptoms. This cross-sectional study utilized a group of veterans with and without GWI (n=61) to investigate: 1) the unique impact that GWI has on a survey measure of attention and memory or the Paced Auditory Serial Addition Test (PASAT). We also investigated how PTSD symptoms, followed by fatigue levels, improved the GWI model …

Verbal Working Memory Load Dissociates Common Indices Of The Numerical Distance Effect: Implications For The Study Of Numerical Cognition, Erin A. Maloney, Nathaniel Barr, Evan F. Risko, Jonathan A. Fugelsang

Publications and Scholarship

In four experiments, we explore the role that verbal WM plays in numerical comparison. Experiment 1 demonstrates that verbal WM load differentially impacts the two most common variants of numerical comparison tasks, evidenced by distinct modulation of the size of the numerical distance effect (NDE). Specifically, when comparing one Arabic digit to a standard, the size of the NDE increases as a function of increased verbal WM load; however, when comparing two simultaneously presented Arabic digits, the size of the NDE decreases (and here is eliminated) as a function of an increased verbal WM load. Experiment 2, using the same …

Forgetting Distractors: Inhibition Or Decay?, Laura Werner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on forgetting irrelevant information in working memory (WM) has supported two

conflicting theories, inhibition (Oberauer & Lewndowsky, 2016) and decay (Dagry et al., 2017;

Dagry & Barrouillet, 2017). However, these conflicting results may be due to the fact that different methods were used to assess each model. In Experiment 1, we combined those methods to create a modified distractor span task that allows for a direct comparison of the models. Participants processed words that were to be remembered (targets) and others that were to be forgotten (distractors); the amount of free time after each distractor varied, with total trial …

The Influence Of Depression And Anxiety On Working Memory In Children With Adhd, Angel David

Doctor of Psychology (PsyD)

Attention Deficit-Hyperactivity Disorder (ADHD) is one of the most common disorders diagnosed in children (Feldman & Reiff, 2014). ADHD is known to impact a child’s working memory, with deficits ranging from mild to severe (Bedard et al., 2014). Research has explored the performance of working memory in children with ADHD and individual co-occurring disorders, finding that internalizing disorders such as depression and anxiety, both independently negatively impact working memory performance (Kofler et al., 2011; Saarinen et al., 2015; Skogan et al., 2013). However, there is limited research on how multiple co-occurring diagnoses in children with ADHD impact working memory. More …

Individual Differences In Executive Function And Reappraisal: A Latent-Variable Analysis, Wei Xing Toh

Dissertations and Theses Collection (Open Access)

Cognitive reappraisal is an adaptive emotion regulation strategy that positively impacts various facets of adaptive functioning (e.g., interpersonal relations, subjective well-being). Although reappraisal implicates cognitive processing, a clear consensus concerning the cognitive underpinnings of reappraisal has not yet been reached. Therefore, we examined how executive function (EF)—i.e., three general-purpose control abilities comprising working memory, inhibition, and shifting—are associated with performance-based reappraisal ability and self-reported reappraisal frequency. Using a latent-variable approach, we found that the shared variance among EF tasks (i.e., common EF)—a general goal-management ability that facilitates the active maintenance of task goals—significantly predicted reappraisal ability, but not reappraisal frequency. …

Sequential Encoding In Visual Working Memory: In The Absence Of Structure, Recency Determines Performance, Jeffery Durbin

Masters Theses

Most prior investigations of visual working memory (VWM) presented the to-be-remembered items simultaneously in a static configuration (e.g., Luck & Vogel, 1997). However, in everyday situations, such as driving on a busy multilane highway, items (e.g., cars) are presented sequentially and must be retained to support later actions (e.g., knowing if it’s safe to change lanes). In a simultaneous presentation, the relative positions of items are apparent but for sequential presentation, relative positions must be inferred in relation to the background structure (e.g., highway lane markings). To examine sequential encoding in VWM, we developed a novel task in which dots …

Examining Relations Between Executive Functions And Decoding: A Meta-Analytic Investigation, Teresa Ober

Dissertations, Theses, and Capstone Projects

Introduction: The Simple View of Reading (SVR) is one of several established models of reading that present decoding and linguistic comprehension as critical skills in the development of reading competencies. Previous research has highlighted the connection between reading comprehension and cognitive skills, including those which fall under the term of executive functions (EF; for a review, see Follmer, 2018). EF may also be critical in the development of decoding. According to the dual route model of word recognition (Coltheart, 2006), decoding involves two separable processes; the phonological route, involving encoding and retrieval of letter-sound associations (also called phoneme-to-grapheme correspondence rules), …

Expertise Within Working Memory And Fluid Intellgence, Addie Wikowsky

MSU Graduate Theses

Working memory, fluid intelligence, and expertise are all psychological concepts that have been explored in the field. Working memory, defined by Baddeley (1986), is the temporary storage of stimuli presented to a person. The relationship between working memory and fluid intelligence is a common theme among studies. Fluid intelligence is one of the components of general intelligence (g). Specifically, fluid intelligence can be described as being able to adapt thinking, even with no previous knowledge (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). Expertise is another critical factor in these studies and is the acquisition of knowledge and being able to apply …

Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.

Electronic Theses and Dissertations

Cognitive flexibility is a hallmark of individuals with higher working memory capacity (WMC). Yet, research demonstrates that higher WMC individuals are sometimes more likely to adopt rigid problem-solving approaches. The present research examines a novel account for these contradictory findings—that different WMC mechanisms interact in ways that both support and constrain cognitive flexibility. Across three studies, participants completed the water jug task—a problem-solving task requiring them to first establish and then break mental set using a complex strategy. Participants then completed measures targeting three WMC mechanisms: attention control, primary memory, and secondary memory. Study 1 demonstrated that primary memory and …

The Impact Of Musical Components On Retrieval Performance, Adkins Franklin Dane

Masters Theses & Specialist Projects

Many students claim that they can study well while listening to music (Anderson & Fuller, 2010; Patton, Stinard, & Routh, 1983), but how does listening to music affect students’ ability to encode and recall studied information? Previous research on background music and attention has revealed mixed results, with some studies indicating that background music can help reduce inattentional blindness (Beanland, Allen, & Pammer, 2011), while others suggest that music may hinder the attention of the listener (by Shih, Huang, & Chaing, 2012). Additionally, individual differences in working memory capacity impact one’s ability to store and retrieve information, as well as …

Do Schools Promote Executive Functions? Differential Working Memory Growth Across School-Year And Summer Months, Jenna E. Finch

Department of Psychology: Faculty Publications

Children’s working memory (WM) skills, which support both academic and social success, continue to improve significantly through the school years. This study leverages the first nationally representative data set with direct assessments of elementary school students’ WM skills to examine whether WM grows more during the school year or summer months and whether WM growth rates differ by household income. Results demonstrate that WM skills grow more during the school-year months compared to the summer months, suggesting that school environments provide children with unique opportunities to improve and practice their WM skills. Further, lower-income children have significantly faster WM growth …

Working Memory And Mindfulness In An Rct Of Abbt And Ar, Anna M. Hall

Graduate Masters Theses

Working memory capacity (WMC) can be degraded by anxiety, stress, and worry, but can also be protected by mindfulness interventions (Jha et al., 2010). The current study was the first to investigate the relations between WMC, anxiety, and mindfulness within two interventions for Generalized Anxiety Disorder (GAD) that promote mindfulness: Acceptance Based Behavioral Therapy (ABBT) and Applied Relaxation (AR). In this exploratory study, we analyzed a subset of participants from a RCT of ABBT and AR who had completed the Operation Span Task (OSPAN; n = 21). First, we found that pre- to post-treatment measures of WMC (e.g., OSPAN scores) …

The Interaction Of Individual Working Memory Capacity With Cognitive Linguistics-Based And Translation-Based Instructional Treatments During The Acquisition Of Polysemous L2 Spanish Spatial Prepositions, Joseph F. Letexier

Theses and Dissertations

The present study investigated three areas in SLA related to the acquisition of polysemous L2 Spanish spatial prepositions. These three areas were (1) the effect of instructional method on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions, (2) the effect of working memory capacity on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions, and (3) the effects resulting from the interaction of working memory capacity with instructional method on the acquisition of productive knowledge of polysemous L2 Spanish spatial prepositions. The target learners were adult L1 English speakers 18 years of age or over …

Cognitive Factors And Parasympathetic Regulation As Interacting Mechanisms Of Attention-Deficit/Hyperactivity Disorder, Anthony R. Ward

FIU Electronic Theses and Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is among the most commonly diagnosed mental health disorders in childhood, and yet, the causal mechanisms of the disorder remain unclear. Deficits in attention regulation, inhibition, and working memory are frequently proposed as core mechanisms of ADHD, but these deficits are highly heterogeneous at the individual level, which hampers advances in understanding the etiology of the disorder. Recent research has shown that parasympathetic nervous system (PNS) regulation is linked to cognitive function and emotion regulation; atypical PNS regulation is associated with problems in these domains as well as higher risk for psychopathology overall. This dissertation examined aspects …

Experimentally Examining The Proposed Relationships Among “Rehearsal-Based” Effects, Corey Ian Mcgill

LSU Doctoral Dissertations

Despite the importance of rehearsal to most models of verbal working memory, its role has been recently called into question. Much prior work in support of rehearsal models has centered on the experimental effects of word-length, phonological-similarity, and irrelevant sound on serial order recall performance and the interaction of all three with concurrent articulation. However, recent research has suggested that confounding effects of stimuli, such as orthographic neighborhood, may be the true cause of the word-length effect. While these findings alone have significant implications for modern models of rehearsal, to understand them within the context of modern theories of working …

Working Memory And Auditory Imagery Predict Sensorimotor Synchronisation With Expressively Timed Music, Ian D. Colley, Peter E. Keller, Andrea R. Halpern

Andrea Halpern

Sensorimotor synchronisation (SMS) is prevalent and readily studied in musical settings, as most people are able to perceive and synchronise with a beat (e.g., by finger tapping). We took an individual differences approach to understanding SMS to real music characterised by expressive timing (i.e., fluctuating beat regularity). Given the dynamic nature of SMS, we hypothesised that individual differences in working memory and auditory imagery—both fluid cognitive processes—would predict SMS at two levels: (1) mean absolute asynchrony (a measure of synchronisation error) and (2) anticipatory timing (i.e., predicting, rather than reacting to beat intervals). In Experiment 1, participants completed two working …

Score One For Jazz: Working Memory In Jazz And Classical Musicians, Bryan E. Nichols, Clemens Wöllner, Andrea R. Halpern

Andrea Halpern

Jazz musicians rely on different skills than do classical musicians for successful performances. We investigated the working memory span of classical and jazz student musicians on musical and nonmusical working memory tasks. College-aged musicians completed the Bucknell Auditory Imagery Scale, followed by verbal working memory tests and musical working memory tests that included visual and auditory presentation modes and written or played recall. Participants were asked to recall the last word (or pitch) from each task after a distraction task, by writing, speaking, or playing the pitch on the piano. Jazz musicians recalled more pitches that were presented in auditory …
