Is Chunking Multimodal?: Music Reading Expertise Effects On Eye Movements During A Cross-Modal Visual Search Paradigm, Nicole Arco
Is Chunking Multimodal?: Music Reading Expertise Effects On Eye Movements During A Cross-Modal Visual Search Paradigm, Nicole Arco
Electronic Theses & Dissertations (2024 - present)
Experts show performance advantages during visual search due to their extensive experience with domain-specific stimuli. Experts form memory representations for meaningful visual patterns, called chunks, that group together multiple chess features. Prior work suggests that the ability for experts to precisely encode a search template facilitates visual search performance (e.g. Hout & Goldinger, 2015). In music, expert musicians might also form chunks (see e.g., Maturi & Sheridan, 2020), although it is unclear what constitutes a chunk in music. The current study addressed the possibility that chunks are multimodal by introducing a new auditory-visual cross-modal version of the visual search paradigm …
Beyond The Surface: A Novel In-Game Behavioral Observation Matrix To Assess Video Game Expertise, Sam A. Leif
Beyond The Surface: A Novel In-Game Behavioral Observation Matrix To Assess Video Game Expertise, Sam A. Leif
UNLV Theses, Dissertations, Professional Papers, and Capstones
In the evolving landscape of gaming, a need for reliable methods to differentiate expertise levels among players has emerged. This study defines experts by their exceptional skills, domain-specific knowledge, and successful application of these attributes in complex situations. Unlike conventional methods that rely on self-reported experience for expertise stratification, this research proposes a shift towards systematic behavioral observation for a more reliable assessment of expertise. The Model of Domain Learning (MDL) facilitates empirical differentiation between novice, competent, and expert categories, allowing for appropriate stratification. Drawing from digital proxemics theory and adapted from the behavioral assessment matrix used by McCreery and …
The Role Of Accuracy In Children’S Judgments Of Experts’ Knowledge., Allison J. Williams
The Role Of Accuracy In Children’S Judgments Of Experts’ Knowledge., Allison J. Williams
Electronic Theses and Dissertations
Children prefer to trust people with expertise and people who are accurate. Because experts make mistakes and give incorrect information (e.g., predictions and diagnoses), this dissertation explores children’s judgments of knowledge for experts who provide inaccurate information. Across two studies, 6- to 9-years-olds (N = 160) were introduced to two experts in different domains (doctor and mechanic) and rated how much each expert knows about their relevant domain. Then, over four consecutive trials, participants heard one expert give inaccurate answers to easy questions in their domain. After each trial, children explained why they believed the expert gave inaccurate answers …
Eye-Movements Of Vocal Performers Across Experience Levels, Charlotte Kelly
Eye-Movements Of Vocal Performers Across Experience Levels, Charlotte Kelly
Honors Program Theses
Expertise, such as music expertise, is commonly studied through an analysis of eye-movements. Experts typically have fewer fixations, longer saccade amplitudes, and thus greater perceptual spans when reading music than non-experts. Most musical expertise literature is focused on instrumentalists and sight-reading. The current study aimed to extend the research to include vocalists and to see if there are still expertise effects when both experts and non-experts are familiar with the piece of music. Participants were recruited to sing a piece from their choir once when they had first started learning the piece and again right before their concert. They were …

Investigation Of Pilots' Visual Entropy And Eye Fixations For Simulated Flights Consisted Of Multiple Take-Offs And Landings, Salem M. Naeeri Ph.D., Ziho Kang Ph.D., Ricardo Palma Fraga M.S.
Journal of Aviation/Aerospace Education & Research
Eye movement characteristics might provide insights on pilots' mental fatigue during prolonged flight. The visual entropy, eye fixation numbers, and eye fixation durations of ten novice pilots and ten expert pilots were analyzed for a four-hour simulated flight task consisting of four consecutive flight legs. Each flight leg lasted approximately one hour and contained five flight phases: takeoff, climb, cruise, descend, and landing. The pilots maneuvered the simulated B-52 aircraft following instrument flight rules (IFR) in a moderate-fidelity Microsoft Flight Simulator environment. Our results indicate that experts’ eye movement characteristics were significantly different from those of novices. In detail, novices' …
Expertise Effects On Visual Change Detection In The Music Reading Domain : Evidence From Eye Movements, Abigail L. Kleinsmith
Expertise Effects On Visual Change Detection In The Music Reading Domain : Evidence From Eye Movements, Abigail L. Kleinsmith
Legacy Theses & Dissertations (2009 - 2024)
Theoretical perspectives in the chess expertise literature, such as chunking and template theories, assume that experts acquire the ability to process domain-specific visual features as larger patterns. Eye tracking techniques can test predictions derived from these theories, because the eye movement record provides fine-grained information about where and when experts are looking during a domain-specific task. In this dissertation, I assessed the generalizability of chunking and template theories to the domain of music reading expertise with a novel music-related variant of the flicker paradigm. Across twoexperiments, I monitored the eye movements of 60 expert musicians (with at least 10 years …
Politicians Polarize And Experts Depolarize Public Support For Covid-19 Management Policies Across Countries, A. Flores, J.C. Cole, S. Dickert, Kimin Eom, G.M. Jiga-Boy, T. Kogut, R. Loria, M. Mayorga, E.J. Pedersen, B. Pereira, E. Rubaltelli, D.K. Sherman, P. Slovic, D. Vastfjall, L. Van Boven

Research Collection School of Social Sciences
Political polarization impeded public support for policies to reduce the spread of COVID-19, much as polarization hinders responses to other contemporary challenges. Unlike previous theory and research that focused on the United States, the present research examined the effects of political elite cues and affective polarization on support for policies to manage the COVID-19 pandemic in seven countries (n = 12,955): Brazil, Israel, Italy, South Korea, Sweden, the United Kingdom, and the United States. Across countries, cues from political elites polarized public attitudes toward COVID-19 policies. Liberal and conservative respondents supported policies proposed by ingroup politicians and parties more than …
What's In A Chunk? : Investigating Expertise Effects On Memory For Complex Visual Search Targets, Kinnera Savitri Maturi
What's In A Chunk? : Investigating Expertise Effects On Memory For Complex Visual Search Targets, Kinnera Savitri Maturi
Legacy Theses & Dissertations (2009 - 2024)
Across two experiments, I examined the extent to which three predictions of the chunking and template framework of expertise generalize to the music-reading domain: 1) Experts show perceptual advantages that allow for superior performance in a domain-specific task; 2) Experts’ can identify familiar patterns, which allow them to rapidly detect relevant regions of a stimulus; and 3) Experts’ superior perceptual abilities are domain-specific. In Study 1, the eye movements of expert musicians and non-musicians were recorded while they searched for a complex visual search target (i.e., a bar of piano sheet music) that was located within a search array (i.e., …
Expertise Within Working Memory And Fluid Intellgence, Addie Wikowsky
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 …
Collaboration: Who, When, And Why To Work Together, Michelle S. Kaplan
Collaboration: Who, When, And Why To Work Together, Michelle S. Kaplan
USF Tampa Graduate Theses and Dissertations
This study looked at how individuals choose whom to work with when a task necessitates collaboration. Prior research done on collaborative environments as well as outcomes of collaboration suggests that who you collaborate with will depend on two primary factors: the individuals from which you have to choose and the circumstances surrounding the task. In the proposed study, these factors will be explored. This thesis identified the lack of literature on informal collaboration, addressing the gap in the literature regarding processes that individuals use when choosing collaborators. This research focused on the influencing factors of similarity and expertise involved in …
Eye Movements Reveal The Visual Component Of Music Expertise : Evidence From A Visual Search Task, Kinnera Savitri Maturi
Eye Movements Reveal The Visual Component Of Music Expertise : Evidence From A Visual Search Task, Kinnera Savitri Maturi
Legacy Theses & Dissertations (2009 - 2024)
An important component of expertise is the ability to rapidly recognize domain-related perceptual patterns. To explore this ability in the domain of music reading, a unique visual search paradigm was used to compare the eye movements of 30 expert musicians (with at least 10 years of music reading skill) and 30 novices (who could not read music). Participants had to match a section of a piece of sheet music (search template) to its identical counterpart within a larger music score (search array). Both the search template and array were presented on the screen simultaneously, which allowed for visual comparisons between …
Knowledge Boundaries Shape The Cognitive And Structural Foundations Of Innovation: Dyad-Level Expertise Exchange In Teams Of Specialists, Daniel Jordan Slyngstad
Knowledge Boundaries Shape The Cognitive And Structural Foundations Of Innovation: Dyad-Level Expertise Exchange In Teams Of Specialists, Daniel Jordan Slyngstad
CGU Theses & Dissertations
Innovation in academia and industry is increasingly achieved via complex problem solving in teams making use of knowledge from multiple areas of expertise. These expertise-diverse teams have proliferated in response to the demands of contemporary knowledge work, and members often possess intellectually distant skillsets that impose novel constraints on the means by which they must collaborate—in particular, they must rely more on distributed taskwork. Yet, research continues to place emphasis on the goal of enabling teams to achieve innovation by increasing knowledge shared in common, overcoming obstacles to cognitive parity, or via sustained periods of problem solving by the team …
Pathways Linking Clinician Demographics To Mental Health Diagnostic Accuracy: An International Perspective, Julia Brechbiel
Pathways Linking Clinician Demographics To Mental Health Diagnostic Accuracy: An International Perspective, Julia Brechbiel
Theses and Dissertations
Significant research efforts have focused on examining the effect of patient factors on providing diagnoses across clinical settings; however, the influence of clinician demographics have received less attention. This study aimed to understand the impact of nonclinical factors such as clinician characteristics and response time on diagnostic accuracy. The study used data from a WHO field study of the ICD-11 development (n = 1822) that required clinicians to diagnose two case vignettes. Clinicians’ slower response times had a significant positive impact on their rates of diagnostic accuracy. However, there was no evidence that clinicians’ demographic features were directly related to …

Sampling Expertise: Incorporating Goal Establishment And Goal Enactment Into Theories Of Expertise To Improve Measures Of Performance, Frank Eric Robinson
Browse all Theses and Dissertations
Task-specific performance measures informed by incomplete theories of expertise do not capture the full range of domain-relevant behaviors, threatening content validity. Surgery is a particularly good example of a domain that has neglected cognitive accounts of performance in favor of task-specific measures of technical skill and experience-based definitions of expertise. Likewise, cognitive accounts of performance tend to neglect skilled performance, including the interaction between automaticity and cognitive control. The present study merges cognition and psychometrics in the context of a surgical task. I analyzed archival surgical performance data from a study of surgical training, including video of human cadaver procedures, …
Exploring Self-Regulation Of More Or Less Expert College-Age Video Game Players: A Sequential Explanatory Design, Meryem Yilmaz Soylu, Roger H. Bruning
Exploring Self-Regulation Of More Or Less Expert College-Age Video Game Players: A Sequential Explanatory Design, Meryem Yilmaz Soylu, Roger H. Bruning
Department of Educational Psychology: Faculty Publications
This study examined differences in self-regulation among college-age expert, moderately expert, and non-expert video game players in playing video games for fun. Winnie's model of self-regulation (Winne, 2001) guided the study. The main assumption of this study was that expert video game players used more processes of self-regulation than the less-expert players. We surveyed 143 college students about their game playing frequency, habits, and use of self-regulation. Data analysis indicated that while playing recreational video games, expert gamers self-regulated more than moderately expert and non-expert players and moderately expert players used more processes of self-regulation than non-experts. Semi-structured interviews also …
Altering The Movement: Learning Effects In Beginning And Well-Practiced Flute Players, Andrea Savord
Altering The Movement: Learning Effects In Beginning And Well-Practiced Flute Players, Andrea Savord
All NMU Master's Theses
This project looks at the extent to which musicians at varying stages of expertise are able to adapt to changes in motor movement (specifically the kinesthetic sense) while playing an instrument. Eight well-practiced and five beginning flute players were tested on playing a major scale on both a modified flute and a traditional flute. The modified flute had altered key positions so that the participants’ right hands were on the same side of the instrument as their left hands. The two modified conditions involved either playing the modified flute with the same fingers as one would play on a traditional …

The Effects Of Mental Models And Expertise On Running Memory And Clinical Handoff Effectiveness, Brittany Lee Anderson-Montoya
Psychology Theses & Dissertations
The goal of the present study was to examine the effects of mental models and expertise on the ability to process handoffs of information. In addition, the role of active or passive processing was examined. Three groups of participants participated, differing in their level of clinical expertise to represent a novice, intermediate, and expert population. Participants performed an abstract running memory span task and two tasks resembling real world activities, an air traffic control (ATC) handoff task, and a clinical handoff task. For all tasks list length and the amount of information to be recalled was manipulated. Further, in the …

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Answering Research Questions Without Calculating The Mean, Guillermo J. Campitelli
Research outputs 2014 to 2021
In an important theoretical article Speelman and McGann (2013) indicated that psychological researchers tend to use statistical procedures that involve calculating the mean of a variable in an uncritical manner. A typical procedure in psychological research consists of calculating the mean of some dependent variable in two or more samples and to present those means as summaries of the samples. The next step is to use some statistical technique (e.g., t -test, ANOVA) in order to be able to determine the probability of finding the observed differences between means in those samples given that the difference between the means of …
Memory Behaviour Requires Knowledge Structures, Not Memory Stores, Guillermo J. Campitelli
Memory Behaviour Requires Knowledge Structures, Not Memory Stores, Guillermo J. Campitelli
Research outputs 2014 to 2021
Since the inception of cognitive psychology dominant theories of memory behavior have used the storage metaphor. In the multi-store models (e.g., Broadbent, 1958; Atkinson and Shiffrin, 1968; Baddeley and Hitch, 1974) the memory system comprises one or more short-term memory (STM) stores and a long-term memory (LTM) store. These stores are places where information is located for varying periods of time (i.e., seconds in the STM stores, and minutes to lifetime in the LTM store) and they have varying capacity limits: large for the LTM store, very limited for the STM store—4 to 7 items, see Miller (1956), Broadbent (1958), …

Not Enough Cooks In The Kitchen: An Empirical Test Of A Two-Factor Model Of Work Unit Understaffing, Cristina Keiko Hudson
USF Tampa Graduate Theses and Dissertations
Although most working adults possess a lay understanding of understaffing in the workplace and may, in fact, feel they are experiencing such a stressor, a review of the research literature reveals a general lack of empirical work on understaffing and its consequences. Hudson and Shen (2013, Development and testing of a new measure of understaffing. Paper presented at the Southern Management Association 2013 Meeting, New Orleans, LA) recently proposed a new model of understaffing that distinguished between two types of personnel deficiencies, manpower and expertise shortages, and linked these dimensions to worker well-being and attitudinal outcomes and identified likely mediating …

You Can’T Teach Speed: Sprinters Falsify The Deliberate Practice Model Of Expertise, Michael P. Lombardo, Robert O. Deaner
Funded Articles
Many scientists agree that expertise requires both innate talent and proper training. Nevertheless, the highly influential deliberate practice model (DPM) of expertise holds that talent does not exist or makes a negligible contribution to performance. It predicts that initial performance will be unrelated to achieving expertise and that 10 years of deliberate practice is necessary.We tested these predictions in the domain of sprinting. In Studies 1 and 2 we reviewed biographies of 15 Olympic champions and the 20 fastest American men in U.S. history. In all documented cases, sprinters were exceptional prior to initiating training, and most reached world class …

Holding A Stick At Both Ends: On Faces And Expertise, Assaf Harel, Dwight J. Kravitz, Chris I. Baker
Psychology Faculty Publications
Ever since Diamond and Carey's (1986) seminal work, object expertise has often been viewed through the prism of face perception (for a thorough discussion, see Tanaka and Gauthier, 1997; Sheinberg and Tarr, 2010). According to Wong and Wong (2014, W&W), however, this emphasis has simply been a response to the question of modularity of face perception, and has not been about expertise in and of itself. It is precisely this conflation of questions of expertise and modularity, the consequent focus on FFA, and the detrimental effect this had on the field of object expertise research that we discussed as part …
Expertise, Democratic Values, And Tolerance, Erika D. Price
Expertise, Democratic Values, And Tolerance, Erika D. Price
Dissertations
Political tolerance (the willingness to extend civil liberties to disliked groups) has been disturbingly low among the American public since measurement of tolerance began in the 1950's. The few voters who do exhibit tolerant attitudes tend to be people who know a great deal about politics (i.e. people high in "political expertise"). Researchers have theorized many explanations for why political experts are more tolerant on average; for example, experts may place more value on the legal and normative `rules' of democracy (i.e. "democratic norms"), which guarantee free speech, or they may consider democratic norms to be more important than non-experts …

Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek
Dissertations, Master's Theses and Master's Reports - Open
Over 2 million Anterior Cruciate Ligament (ACL) injuries occur annually worldwide resulting in considerable economic and health burdens (e.g., suffering, surgery, loss of function, risk for re-injury, and osteoarthritis). Current screening methods are effective but they generally rely on expensive and time-consuming biomechanical movement analysis, and thus are impractical solutions. In this dissertation, I report on a series of studies that begins to investigate one potentially efficient alternative to biomechanical screening, namely skilled observational risk assessment (e.g., having experts estimate risk based on observations of athletes movements). Specifically, in Study 1 I discovered that ACL injury risk can be accurately …

The Acquisition Of Expertise In The Classroom: Are Current Models Of Education Appropriate?, Craig P. Speelman
Research outputs 2014 to 2021
The study of expertise tends to focus on humans who can perform extraordinary feats. Although the way in which expertise is acquired is often characterized as similar to everyday skill acquisition, the attainment of basic numeracy skills is rarely considered in the same context as the attainment of expertise. It is clear, though, that average numeracy skills possess all the hallmarks of expert performance. In this paper I argue that the traditional classroom of Western education systems pays insufficient attention to the idea that effective numeracy skills represent a level of expertise that requires a particular form of training. Using …

Real-world expertise provides a valuable opportunity to understand how experience shapes human behavior and neural function. In the visual domain, the study of expert object recognition, such as in car enthusiasts or bird watchers, has produced a large, growing, and often-controversial literature. Here, we synthesize this literature, focusing primarily on results from functional brain imaging, and propose an interactive framework that incorporates the impact of high-level factors, such as attention and conceptual knowledge, in supporting expertise. This framework contrasts with the perceptual view of object expertise that has concentrated largely on stimulus-driven processing in visual cortex. One prominent version of …
