Experimentally Examining The Proposed Relationships Among “Rehearsal-Based” Effects, Corey Ian Mcgill Jan 2019

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 …

The Effects Of Working Memory Training And Encoding Strategy On Working Memory Capacity, Frank Tuthill Jun 2018

The Effects Of Working Memory Training And Encoding Strategy On Working Memory Capacity, Frank Tuthill

Electronic Theses, Projects, and Dissertations

Undergraduate students from California State University, San Bernardino were recruited to examine the effects of working memory training and encoding strategy upon working memory capacity. Participants will be prescreened for low working memory capacity, and then will be tested on a battery of complex span measures. Participants will be divided into several strategy conditions: rehearsal, visual, and control. Then participants will be tested on their verbal working memory both before and after the 20 session n-back working memory training program. Participants are predicted to do the same or worse with the strategy instruction before working memory training while they will …

Examining The Influence Of Executive Resources And Mathematical Abilities On Framing Biases, Gabriel Allred May 2018

Examining The Influence Of Executive Resources And Mathematical Abilities On Framing Biases, Gabriel Allred

UNLV Theses, Dissertations, Professional Papers, and Capstones

The finding that the presentation of a choice (i.e., either as a loss or a gain) can affect and bias our willingness to engage in risk is one of the paramount findings of behavioral economics. First discussed by Tversky and Kahneman (1981), the framing effect demonstrates that when given two choices framed as a loss, we tend to become risk seeking. However, when the exact same outcome is presented as a gain, we become risk averse, choosing the more conservative option, regardless of the actual expected value. The effect is not limited to general research samples but has been demonstrated …

Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas Jan 2018

Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas

Honors Undergraduate Theses

The intent of this thesis is to examine the psychometric properties of a complex span task (CST) developed to measure working memory capacity (WMC) using measurements obtained from a sample of 68 undergraduate students at the University of Central Florida. The Grocery List Task (GLT) promises several design improvements over traditional CSTs in a prior study about individual differences in WMC and distraction effects on driving performance, and it offers potential benefits for studying WMC as well as the serial-position effect. Currently, the working memory system is composed of domain-general memorial storage processes and information-processing, which involves the use of …

The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain Jan 2018

The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain

USC Aiken Psychology Theses

Research has shown that anxiety impairs attention and working memory, especially when it comes to completing a mentally demanding cognitive task such as the emotional Stroop paradigm or the n-back task. The purpose of this study was to investigate whether state anxiety affects behavioral performance on executive function tasks. State anxiety was induced using negatively valenced images from the International Affective Picture System, while neutral images served as the control. We compared behavioral performance between individuals in the negative mood induction against those in the neutral mood induction. Trait anxiety was used as a covariate for both groups. This allowed …

Score One For Jazz: Working Memory In Jazz And Classical Musicians, Bryan E. Nichols, Clemens Wöllner, Andrea R. Halpern Jan 2018

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

Faculty Journal Articles

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 …

Working Memory And Auditory Imagery Predict Sensorimotor Synchronisation With Expressively Timed Music, Ian D. Colley, Peter E. Keller, Andrea R. Halpern Jan 2018

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

Faculty Journal Articles

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 …

The Modulatory Effect Of Expectations On Memory Retrieval During Sentence Comprehension, Luca Campanelli, Julie A. Van Dyke, Klara Marton Jan 2018

The Modulatory Effect Of Expectations On Memory Retrieval During Sentence Comprehension, Luca Campanelli, Julie A. Van Dyke, Klara Marton

Publications and Research

Memory retrieval and probabilistic expectations are recognized factors in sentence comprehension that capture two different critical aspects of processing difficulty: the cost of retrieving and integrating previously processed elements with the new input words and the cost of incorrect predictions about upcoming words or structures in a sentence. Although these two factors have independently received substantial support from the extant literature, how they interact remains poorly understood. The present study investigated memory retrieval and expectation in a single experiment, pitting these factors against each other. Results showed a significant interference effect in both response time to the comprehension questions and …

Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte Dec 2017

Examining Attentional Control And Processing Speed Deficits As Underlying Mechanisms Of Neuropsychological Impairment In Schizophrenia, Mayte Forte

Graduate Masters Theses

Neuropsychological impairment is a key characteristic of schizophrenia (SZ), but its cognitive profile and underlying information processing mechanisms are not yet well understood. We compare patterns of neuropsychological functioning in 85 persons with SZ and 76 healthy controls across measures of intelligence, memory, and executive function. We then test the hypothesis that neuropsychological impairment in SZ is related to dual deficits in two related but distinct information processes: processing speed and attentional control. All research participants completed Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), Wechsler Memory Scale Third Edition (WMS-III), and Wisconsin Card Sorting Test (WCST), all of which provided measures …

Examining The Concurrent And Predictive Relations Of Working Memory In Childhood Attention-Deficit/Hyperactivity Disorder, Ashley N. Simone Sep 2017

Examining The Concurrent And Predictive Relations Of Working Memory In Childhood Attention-Deficit/Hyperactivity Disorder, Ashley N. Simone

Dissertations, Theses, and Capstone Projects

Attention-deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder characterized by developmentally inappropriate levels of inattention and/or hyperactivity/impulsivity which lead to impairment in multiple settings (American Psychiatric Association, 2013). Childhood ADHD has been concurrently associated with various neurocognitive deficits and one in particular that has been under examination over the past several years is working memory (WM). WM is a temporary storage system that is responsible for maintenance and/or manipulation of information in order to complete complex cognitive and behavioral tasks. Researchers have postulated that WM is one of several potential endophenotypes of ADHD (Castellanos & Tannock, 2002) and/or that WM is …

Pitch Imitation Ability In Mental Transformations Of Melodies, Emma B. Greenspon, Peter Q. Pfordresher, Andrea R. Halpern Jan 2017

Pitch Imitation Ability In Mental Transformations Of Melodies, Emma B. Greenspon, Peter Q. Pfordresher, Andrea R. Halpern

Faculty Journal Articles

Previous research suggests that individuals with a vocal pitch imitation deficit (VPID, a.k.a. "poor-pitch singers") experience less vivid auditory images than accurate imitators (pfordresher & halpern, 2013), based on self-report. in the present research we sought to test this proposal directly by having accurate and VPID imitators produce or recognize short melodies based on their original form (untransformed), or after mentally transforming the auditory image of the melody. For the production task, group differences were largest during the untransformed imitation task. importantly, producing mental transformations of the auditory image degraded performance for all participants, but were relatively more disruptive to …

Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens Jan 2017

Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens

College of Graduate Studies: Theses & Dissertations

If an organism is trained to approach a location within an enclosure the organism will approach the correct location and it’s geometrically identical location within the environment upon removal of any features. This phenomenon has been turned spatial reorientation, and further studies on how, and to what, organisms reorient have conducted in the last several decades. In the reorientation literature, two theories have surfaced to fill the void left by the rejection of the initial reorientation theory, the Geometric Module theory. I attempt look to discern if the synonym judgement dual task will hinder reorientation in a similar or different …

Are All Interferences Bad? Bilingual Advantages In Working Memory Are Modulated By Varying Demands For Controlled Processing, Hwajin Yang, Sujin Yang Jan 2017

Are All Interferences Bad? Bilingual Advantages In Working Memory Are Modulated By Varying Demands For Controlled Processing, Hwajin Yang, Sujin Yang

Research Collection School of Social Sciences

We investigated bilingual advantages in general control abilities using three complex-span tasks of working memory (WM). An operation-span task served as a baseline measure of WM capacity. Additionally, two modified versions of the Stroop-span task were designed to place varying attentional-control demands during memoranda encoding by asking participants either to read the to-be-remembered item aloud (lower cognitive control; i.e., Stroop-span task) or to name the font color of the to-be-remembered item while still encoding the word for later recall (greater cognitive control; i.e., attention-impeded Stroop-span task). Twenty-six Korean-English bilinguals and 25 English-native monolinguals were tested. We found that bilinguals outperformed …

A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths Jan 2016

A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths

Faculty Journal Articles

The brain basis for auditory working memory, the process of actively maintaining sounds in memory over short periods of time, is controversial. Using functional magnetic resonance imaging in human participants, we demonstrate that the maintenance of single tones in memory is associated with activation in auditory cortex. In addition, sustained activation was observed in hippocampus and inferior frontal gyrus. Multivoxel pattern analysis showed that patterns of activity in auditory cortex and left inferior frontal gyrus distinguished the tone that was maintained in memory. Functional connectivity during maintenance was demonstrated between auditory cortex and both the hippocampus and inferior frontal cortex. …

Working Memory And Interference Control In Children With Specific Language Impairment, Klara Marton, Naomi Eichorn, Luca Campanelli, Lilla Zakarias Jan 2016

Working Memory And Interference Control In Children With Specific Language Impairment, Klara Marton, Naomi Eichorn, Luca Campanelli, Lilla Zakarias

Publications and Research

Language and communication disorders are often associated with deficits in working memory (WM) and interference control. WM studies involving children with specific language impairment (SLI) have traditionally been framed using either resource theories or decay accounts, particularly Baddeley's model. Although significant interference problems in children with SLI are apparent in error analysis data from WM and language tasks, interference theories and paradigms have not been widely used in the SLI literature. A primary goal of the present paper is to provide an overview of interference deficits in children with SLI. Review of the extant literature on interference control shows deficits …

Working Memory And Cued Recall, Max V. Fey, Karen Naufel, Lawrence Locker Jan 2016

Working Memory And Cued Recall, Max V. Fey, Karen Naufel, Lawrence Locker

Honors College Theses

Previous research has found that individuals with high working memory have greater recall capabilities than those with low working memory (Unsworth, Spiller, & Brewers, 2012). Research did not test the extent to which cues affect one’s recall ability in relation to working memory. The present study will examine this issue. Participants completed a working memory measure. Then, they were provided with cued recall tasks whereby they recalled Facebook friends. The cues varied to be no cues, ambiguous cues high in imageability, and cues directly related to Facebook. The results showed that there was no difference between individual’s ability to recall …

Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee Oct 2015

Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee

Psychology Theses & Dissertations

Some theories propose that insight involves automatic processes that are responsible for restructuring. Other theories postulate that the mechanisms surrounding restructuring are controlled and effortful. The current study tested these theories by comparing different methodology and operational definitions that have been used in previous research to investigate the nature of “Aha!” experiences and impasse in insightful problem solving. One hundred two undergraduate psychology students from Old Dominion University completed working memory tasks, six classic insight problems, and gave initial problem representation ratings for the insight problems before solution attempt. Using a think-aloud protocol, we assessed the occurrence of impasse during …

Effects Of Nicotine On A Translational Model Of Working Memory, David Alderson Macqueen Sep 2015

Effects Of Nicotine On A Translational Model Of Working Memory, David Alderson Macqueen

USF Tampa Graduate Theses and Dissertations

Cognitive research with human non-smokers has demonstrated that nicotine generally enhances performance on tasks of attention but, working memory does not appear to be affected. In contrast, nicotine has been shown to produce robust enhancements of working memory in non-human animals. To address this disparity, the present study investigated the effects of nicotine (2mg, 4mg nicotine gum, and placebo) on the performance of 30 non-smokers (15 male) completing a working memory task developed for rodents (the odor span task, OST). Nicotine has been reported to enhance OST performance in rodents and the present study sought to determine whether the effect …

The Impact Of Evaluative Pressure And Higher Working Memory Capacity On Sensorimotor Skill Performance., Lauren Grant May 2015

The Impact Of Evaluative Pressure And Higher Working Memory Capacity On Sensorimotor Skill Performance., Lauren Grant

College of Arts & Sciences Senior Theses

Underperformance in high-pressure situations, commonly known as choking under pressure, has been well-documented in the literature. For well-learned sensorimotor skills, such as sports, choking is thought to occur because individuals devote explicit attention to the steps of the skill, which disrupts performance. The current study examines how the type of pressure situation an individual experiences, and individual differences in working memory capacity, influence choking on a sensorimotor skill. Participants (N = 96) performed a Sensorimotor Reaction Time Task (SRTT) either under monitoring pressure, outcome pressure, or no pressure (control). High working-memory individuals performed significantly worse while completing the SRTT under …

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster Jan 2015

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster

Theses and Dissertations--Clinical and Translational Science

This dissertation introduces a framework for understanding differences in how emotional enhancement effects might influence memory in aging adults and then summarizes the findings of three studies of how repetition effects and emotional enhancement effects influence working memory in older adults without cognitive impairment (NC), older adults with amnestic mild cognitive impairment (MCI), and older adults with mild Alzheimer’s disease (AD). In these experiments, individuals with AD showed cognitive impairment in terms of accuracy and reaction time, but individuals with MCI showed milder behavioral impairment that was confined to manipulations of working memory. Individuals with AD showed relative sparing of …

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn Oct 2014

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty Jan 2014

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty

Wayne State University Dissertations

Accumulation of non-heme iron in the brain has been theorized as a cellular mechanism underlying global neural and cognitive decline in normal aging and neurodegenerative disease. Relatively few studies of brain iron in normal aging exist and extant studies are almost exclusively cross-sectional. Here, I estimated iron content via T2* and measured volumes in several brain regions in two independent samples of healthy adults. The first sample (N = 89) was measured twice with a two-year delay; and the second sample (N = 32) was assessed four times over a span of 7 years. Latent models estimated change in iron …

Contribution Of Reactive And Proactive Control To Children’S Working Memory Performance: Insight From Item Recall Durations In Response Sequence Planning, Nicolas Chevalier, Tiffany D. James, Sandra A. Wiebe, Jennifer Mize Nelson, Kimberly Espy Jan 2014

Contribution Of Reactive And Proactive Control To Children’S Working Memory Performance: Insight From Item Recall Durations In Response Sequence Planning, Nicolas Chevalier, Tiffany D. James, Sandra A. Wiebe, Jennifer Mize Nelson, Kimberly Espy

Department of Psychology: Faculty Publications

The present study addressed whether developmental improvement in working memory span task performance relies upon a growing ability to proactively plan response sequences during childhood. Two hundred thirteen children completed a working memory span task in which they used a touchscreen to reproduce orally presented sequences of animal names. Children were assessed longitudinally at 7 time points between 3 and 10 years of age. Twenty-one young adults also completed the same task. Proactive response sequence planning was assessed by comparing recall durations for the 1st item (preparatory interval) and subsequent items. At preschool age, the preparatory interval was generally shorter …

The Effects Of Diagrams And Relational Complexity On User Performance In Conditional Probability Problems In A Non-Learning Context, Vincent J. Kellen Jun 2012

The Effects Of Diagrams And Relational Complexity On User Performance In Conditional Probability Problems In A Non-Learning Context, Vincent J. Kellen

College of Computing and Digital Media Dissertations

Many disciplines in everyday life depend on improved performance in conditional probability problems. Most adults struggle with conditional probability problems and several prior studies have shown participant accuracy is less than 50%. This study examined user performance when aided with computer-generated Venn and Euler type diagrams in a non-learning context. Despite the prevalence of research into diagrams and extensive research into conditional probability problem solving, this study is one of the only studies to apply theories of working memory to predict user performance in conditional probability problems with diagrams. Following relational complexity theory, this study manipulated problem complexity in computer …

The Effects Of Distraction And A Brief Intervention On Auditory And Visual-Spatial Working Memory In College Students With Attention Deficit Hyperactivity Disorder, Tara T. Lineweaver, Suneeta Kercood, Nicole B. O'Keeffe, Kathleen M. O'Brien, Eric J. Massey, Samantha J. Campbell, Jenna M. Pierce

Scholarship and Professional Work - LAS

Two studies addressed how young adult college students with attention deficit hyperactivity disorder (ADHD) (n = 44) compare to their nonaffected peers (n = 42) on tests of auditory and visual–spatial working memory (WM), are vulnerable to auditory and visual distractions, and are affected by a simple intervention. Students with ADHD demonstrated worse auditory WM than did controls. A near significant trend indicated that auditory distractions interfered with the visual WM of both groups and that, whereas controls were also vulnerable to visual distractions, visual distractions improved visualWM in the ADHD group. The intervention was ineffective. Limited correlations emerged between …

Improving Memory Using N-Back Training, Paul Beavon Jan 2012

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …
