A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths
A Brain System For Auditory Working Memory, Sukhbinder Kumar, Sabine Joseph, Phillip E. Gander, Nicolas Barascud, Andrea R. Halpern, Timothy D. Griffiths
Andrea Halpern
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. …
Spatial Memory For Isolated Arm Locations On The Radial Maze, Hayden Macdonald
Spatial Memory For Isolated Arm Locations On The Radial Maze, Hayden Macdonald
Electronic Thesis and Dissertation Repository
The ability to encode and retrieve information describing spatial locations allows organisms to solve a variety of natural problems. When multiple spatial locations vary with respect to foraging, predatory or environmental factors, successfully discriminating between these locations may result in increased fitness. Although, how do the spatial relations of multiple locations affect the encoding or retrieval of spatial information? Across three radial maze experiments, I addressed how spatial configuration affects working memory for multiple locations. Specifically, I asked 1) how spatial patterns affect memory for multiple locations, 2) how spatial isolation between to-be-visited locations may affect spatial memory, and 3) …
The Effects Of Working Memory Training And Encoding Strategy On Working Memory Capacity, Frank Tuthill
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
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 …
The Effects Anxiety Has On Attentional Bias And Working Memory, Breana Mcswain
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 …
Working Memory And Auditory Imagery Predict Sensorimotor Synchronisation With Expressively Timed Music, Ian D. Colley, Peter E. Keller, Andrea R. Halpern
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 …
Score One For Jazz: Working Memory In Jazz And Classical Musicians, Bryan E. Nichols, Clemens Wöllner, Andrea R. Halpern
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 …
Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas
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 Modulatory Effect Of Expectations On Memory Retrieval During Sentence Comprehension, Luca Campanelli, Julie A. Van Dyke, Klara Marton
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
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
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 …
Examining The Effects Of Frustration On Working Memory Capacity In An Emerging Adult Sample, Jonathan Parks Fillauer
Examining The Effects Of Frustration On Working Memory Capacity In An Emerging Adult Sample, Jonathan Parks Fillauer
Masters Theses
Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with numerous pejorative outcomes in adults such as low frustration tolerance and deficits in central executive functioning. The present study aims to examine (1) the effect of induced frustration on working memory capacity (WMC) and (2) the unique contribution of ADHD symptoms and other commonly comorbid disorders (i.e., anxiety/depression and alcohol use) to frustration. Participants (N=66) were randomly assigned to either the control group (n=32) or the experimental group (n=34). The Frustration Induction Procedure (FIP) was administered to participants in the experimental group and a neutral, non-frustrating task was administered to a control group. A …
Pitch Imitation Ability In Mental Transformations Of Melodies, Emma B. Greenspon, Peter Q. Pfordresher, Andrea R. Halpern
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
Dual Task Testing Of The Adaptive Combination View In Spatial Reorientation, Donald G. Sullens
Electronic Theses and 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
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 …
Working Memory And Cued Recall, Max V. Fey, Karen Naufel, Lawrence Locker
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 …

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

The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson
Electronic Theses and Dissertations
Acute stress is commonly experienced by many throughout their lives. Given the demanding lifestyle of many career paths, it's important to gauge the influence of these stressors upon cognitive performance. The present dissertation focus' upon explicit learning in attempts to explore one avenue of the stress-cognition relationship. The Trier Social Stress Test (TSST) was used as a lab stressor for Experiments 1 and 2, in which participants are asked to give a speech and complete a difficult math task in front of 2 evaluators trained to monitor non-verbal behavior. Experiment 1 investigates the dynamic stress response during the minutes following …
Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee
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
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
The Impact Of Evaluative Pressure And Higher Working Memory Capacity On Sensorimotor Skill Performance., Lauren Grant
College of Arts & Sciences Senior Honors 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 …
Empirical Validation Of An Executive Function Battery For Use In Childhood And Adolescence, Emma K. Phillips
Empirical Validation Of An Executive Function Battery For Use In Childhood And Adolescence, Emma K. Phillips
Undergraduate Honors Theses
This research explores the reliability and efficacy of a child and adolescent adaptation of an adult battery of executive functioning, measuring the constructs of reasoning, short-term memory and verbal processing. The intent of the research is twofold as it intends to support an age appropriate adjustment of a battery of tasks presented by Hampshire, Highfield, Parkin and Owen (2012), and secondly to display the necessity of looking at executive functions as multifaceted and therefore requiring multiple tasks to encompass their complexities. The adjusted battery in analysis is composed of nine tasks that have been amended to be age appropriate for …

Cognitive training is the process through which individuals perform a series of computerized tasks over a period of weeks for the purpose of improving a variety of cognitive abilities. Cognitive training is important in commercial, clinical, and educational fields alike, considering the possibilities of improving and sustaining cognitive abilities in both typically developing and cognitively deficient populations. The present review assesses cognitive training paradigms targeting working memory. Working memory is a predictor of academic achievement and is closely related to mechanisms of higher cognition. In particular, the present review focuses past studies which have investigated the effects working memory training …
Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster
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 …
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
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
Tara T. Lineweaver
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 …

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn
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 …
The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan
The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan
Electronic Thesis and Dissertation Repository
Statistical language learning is an implicit process wherein language learners track sequential statistics in fluent speech, and may it facilitate the learning of word boundaries. This process is well studied, however, the cognitive mechanisms supporting it remain poorly understood. The present thesis investigated whether domain-specific or cross-domain explicit working memory engagement would impair implicit statistical learning of word boundaries in fluent speech. Participants (n = 110) were exposed to an implicit statistical word segmentation paradigm while concurrently engaged in no other task (control), or an explicit domain- specific (verbal) or cross-domain (visuospatial) working memory task of either low- or high- …
The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
Undergraduate Honors Theses
The present study investigated the interaction between working and reference spatial memory in an effort to develop an animal model of this interaction. Twelve male Long-Evans rats were tested on an eight-arm radial maze in a two-phase procedure. In the study phase, a rat was allowed to enter four randomly selected arms for a food reward placed at the end of each arm. The test phase allowed the rat access to all eight arms, but only the previously unentered arms contained food. Two of the correct test arms were defined as reference memory arms because they were always correct. The …
