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) …

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 …

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

Andrea Halpern

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 …

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. …

Do Familiar Memory Items Decay?, Timothy J. Ricker, Joshua Sandry, Evie Vergauwe, Nelson Cowan

Department of Psychology Faculty Scholarship and Creative Works

There is a long-standing debate over whether the passage of time causes forgetting from working memory, a process called trace decay. Researchers providing evidence against the existence of trace decay generally study memory by presenting familiar verbal memory items for 1 s or more per memory item, during the study period. In contrast, researchers providing evidence for trace decay tend to use unfamiliar nonverbal memory items presented for 1 s or less per memory item, during the study period. Taken together, these investigations suggest that familiar items may not decay while unfamiliar items do decay. The availability of verbal rehearsal …
