The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales
The Structure Of Working Memory: A Review And New View Of Psychometric Models, Kevin Pablo Rosales
CGU Theses & Dissertations
Beginning in the 1970s, a great deal of research in cognitive psychology, developmental psychology, psychometrics, and cognitive neuroscience has investigated the structure and function of working memory (WM), defined as the ability to actively maintain and manipulate information in the service of complex cognition (Baddeley & Hitch, 1974). It is well established that WM is a limited capacity system and individual differences in WM capacity are strongly associated with important cognitive abilities and outcomes, such as general intelligence (Engle et al., 1999) and academic achievement (Swanson & Berninger, 1996; Ramirez et al., 2013). For this reason, WM is a central …
Bridging Psychometric And Cognitive Models Of (General) Intelligence: An Investigation Based On Process Overlap Theory, Han Hao
CGU Theses & Dissertations
Human intelligence has been scientifically investigated as a psychological construct for over a century but there has not been a universally accepted definition or theory. One cause of this problem is that traditional theories attempt to explain the robust findings in cognitive ability testing, such as the positive manifold, from two different perspectives: psychometric or cognitive. Both approaches have their own limitations and are sometimes incompatible with each other. Therefore, contemporary theories of intelligence have been developed to provide a more unified perspective by combining both types of approaches, allowing the psychometric structure of cognitive abilities to be represented and …
Measuring Outcome Expectations In Academic Persistence, Michael Kozlowski
Measuring Outcome Expectations In Academic Persistence, Michael Kozlowski
Theses and Dissertations
Academic persistence, or a student’s decision to leave an institution of higher education, has remained an inveterate puzzle to researchers, theoreticians, institutions, and counselors. Despite a large body of theoretical and empirical literature, the rate at which students leave institutions of higher education has remained stable over the past 50 years. The discipline of counseling psychology has a long tradition of investigating academic persistence from a psychological perspective. Earlier investigations in counseling psychology focused on identifying psychopathological traits, cognitive abilities, and contextual factors associated with a student’s decision to leave. These investigations were met with a sociological reaction that has …
Neural Mechanisms Of Cognitive Individual Difference: An Investigation Of The Human Connectome Project, Shelly Renee Cooper
Neural Mechanisms Of Cognitive Individual Difference: An Investigation Of The Human Connectome Project, Shelly Renee Cooper
Arts & Sciences Electronic Theses and Dissertations
Considering individual differences in task activation functional magnetic resonance imaging (t-fMRI) can be challenging because they may arise from variability in activity in brain regions, in the tasks themselves, or some combination thereof. Delineating sources of between-subjects variance is particularly important for cognitive control where task goals are at the forefront. Here we applied structural equation modeling (SEM) to the Human Connectome Project to examine if activity could be partitioned into separable brain and task individual difference dimensions. A series of SEMs were defined with varying numbers of latent factors, where the inputs were parcels of two cognitive control-related brain …
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 …
Approaching Individual Differences Questions In Cognitive Control: A Case Study Of The Ax-Cpt, Shelly Cooper
Approaching Individual Differences Questions In Cognitive Control: A Case Study Of The Ax-Cpt, Shelly Cooper
Arts & Sciences Electronic Theses and Dissertations
Investigating individual differences in cognition requires addressing questions not often thought about in standard experimental designs, especially those regarding the psychometrics of a task. The purpose of the present study is to use the AX-CPT cognitive control task as a representative case study example to address four concerns that may impact the ability to answer questions related to individual differences. First, the importance of a task's true score variance for evaluating potential failures to replicate predicted individual differences effects is demonstrated. Second, evidence is provided that Internet-based studies (e.g., MTurk) can exhibit comparable, or even higher true score variance than …
Evaluating The Validity Of Technology-Enhanced Educational Assessment Items And Tasks: An Empirical Approach To Studying Item Features And Scoring Rubrics., Ally Thomas
Dissertations, Theses, and Capstone Projects
With the advent of the newly developed Common Core State Standards and the Next Generation Science Standards, innovative assessments, including technology-enhanced items and tasks, will be needed to meet the challenges of developing valid and reliable assessments in a world of computer-based testing. In a recent critique of the next generation assessments in math (i.e., Smarter Balanced), Rasmussen (2015) observed that many aspects of the technology “enhancements” can be expected to do more harm than good as the computer interfaces may introduce construct irrelevant variance. This paper focused on issues surrounding the design of TEIs and how cognitive load …
Invariant Two Component Structure Of The Rbans, Elisabeth M. Vogt
Invariant Two Component Structure Of The Rbans, Elisabeth M. Vogt
Master's Theses (2009 -)
The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS: Randolph, 1998, 2012) is a brief neurocognitive instrument used to evaluate cognitive functioning in clinical settings. While this test is used regularly, investigation of the factor structure has resulted in inconsistent findings across samples. It was hypothesized that inconsistent RBANS dimensional structures are the result of methodological differences and not solely due to unique sample characteristics. The present study utilized empirically supported extraction criteria (Parallel Analysis; Minimum Average Partial Procedure) and uniformly investigated five samples. RBANS data from four samples were previously published (Carlozzi, Horner, Yang, & Tilley, 2008; Duff, …
The Application Of Information Integration Theory To Standard Setting: Setting Cut Scores Using Cognitive Theory, Christopher C. Foster
The Application Of Information Integration Theory To Standard Setting: Setting Cut Scores Using Cognitive Theory, Christopher C. Foster
Doctoral Dissertations
Information integration theory (IIT) is a cognitive psychology theory that is primarily concerned with understanding rater judgments and deriving quantitative values from rater expertise. Since standard setting is a process by which subject matter experts are asked to make expert judgment about test content, it is an ideal context for the application of information integration theory. Information integration theory (IIT) was proposed by Norman H. Anderson, a cognitive psychologist. It is a cognitive theory that is primarily concerned with how an individual integrates information from two or more stimuli to derive a quantitative value. The theory focuses on evaluating the …
Component Numeracy Skills And Decision Making, Saima Ghazal
Component Numeracy Skills And Decision Making, Saima Ghazal
Dissertations, Master's Theses and Master's Reports - Open
Numeracy—i.e., one’s practical understanding of mathematics in context—is one of the strongest predictors of people’s general decision making skill, independent of other cognitive abilities (e.g., intelligence, working memory, attentional control). Despite notable scientific progress on the nature of numeracy and decision making, the cognitive and decision sciences have yet to investigate individual differences in numeracy components (e.g., algebra versus probability). In this dissertation, I report on my efforts to develop new measurement technology and quantitative models of cognitive and decision skills. Analyses include the first known investigations of the relations between the major adult component numeracy skills and general decision …
