Process Dissociation Analyses Of Memory Changes In Healthy Aging, Preclinical, And Very Mild Alzheimer Disease: Evidence For Isolated Recollection Deficits, Peter R. Millar

Arts & Sciences Electronic Theses and Dissertations

Recollection and familiarity are independent processes that contribute to memory performance. Recollection is dependent on attentional control, which breaks down in early-stage Alzheimer disease (AD), whereas familiarity is independent of attention. The present study examines the sensitivity of recollection estimates based on Jacoby’s (1991) process dissociation procedure to AD-related biomarkers in a large sample of well-characterized cognitively normal older adults (N = 519) and the extent to which recollection discriminates these individuals from individuals with very mild symptomatic AD (N = 64). Participants studied word pairs, e.g., “knee bone,” then completed a primed, explicit, cued fragment-completion memory task, e.g., “knee …

Does Use Of Neutralization Techniques Predict Delinquency And Substance Use Outcomes?, Erin C. Siebert

Clinical Psychology Dissertations

This study was part of a larger research intervention that uses motivational interviewing (MI) as part of an in-school substance abuse intervention in local high schools in the greater Seattle area. Our aim was to test hypothesized relationships between marijuana use, other delinquent behavior, and neutralization techniques used by participants and determine their impact on the effectiveness of an MI-based intervention. Hypotheses were that neutralization technique use would decrease the effectiveness of an MI intervention due to the conflicting cognitive processes of justification and developing discrepancy. Of the 84 participants that completed Intake assessments, 60% were male and identified as …

If It Feels Good, View It: Selective Exposure And Desensitization Moderate The Association Between Video Gameplay And Pleasure-Oriented Aggression, Mejdy M. Jabr

University of New Orleans Theses and Dissertations

A number of studies have indicated that violent video gameplay is associated with higher levels of aggression, and desensitization to violent content contributes to this association. Utilizing a rapid serial visual presentation (RSVP) task, the current study used event-related potentials (ERPs) to investigate selective attention (N1 activation), cognitive control (N2 activation), and desensitization (P3 activation) as neurocognitive mechanisms potentially underlying the association between gameplay and subtypes of aggression. Results showed video game players and non-players differed significantly in brain activation when engaged with violent imagery. N1 and P3 amplitude moderated the association between gameplay and pleasure-oriented aggression. Follow-up analyses further …

Does Attentional Slippage Conform To A Simple Gradient?, Katie Rennie

Electronic Theses & Dissertations

The following graduate thesis describes research designed to examine flanker interference at varying spatial distances from a target stimulus. Traditionally, much evidence has accumulated that the distribution of visual attention conforms to a monotonically decreasing gradient in which distractors at the farthest separations produce the least interference (e.g., Erikson & St. James, 1986). Different from this traditional conceptualization, Müller, Mollenhauer, Rösler, and Kleinschmidt (2005) describe what they termed a Mexican hat distribution of visual attention showing flankers at an intermediate zone produce less interference. The current study is designed to investigate whether flanker interference declines monotonically with distance or follows …

Why Therapists Bite Their Tongue In Therapy And What To Do About It, Ingibjorg Thors

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Most therapists agree that therapy should be a place where the unspeakable is speakable, and the role of the therapist should be to help the client find a way to change by exploring the patterns of behavior that are no longer working for the client. Being blunt in therapy seems to be one of the key factors needed to promote immediacy, to challenge habitual ways of thinking that are not productive for our clients, and to create a relationship that is different from social and professional relationships. However, many therapists have distorted beliefs about using bluntness in therapy to stimulate …

Teoria De La Mente Y Sociedad En La Narrativa Policiaca De Lorenzo Silva Y Francisco Garcia Pavon: Estereotipos, Roles De Genero Y Minorias, Jesus Castro Gorfti

Open Access Dissertations

Spanish:

The purpose of this study is to utilize certain aspects of cognitive psychology as a framework to analyze the police procedural novels of two Spanish authors: Francisco García Pavón and Lorenzo Silva. Specifically, we will focus on two main aspects of the mind studied by the cognitive sciences: Theory of Mind and metarepresentations. Theory of Mind (ToM) refers to the capacity that human beings have to attribute mental states to other humans, as well as oneself, based on their bodily and facial gestures. The concept of metarepresentation refers to the ability of humans to keep track of who said …

Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers

Open Access Theses

Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …

Fitting Eyewitness Identification And Confidence To A Diffusion Model Of Processing, Brittany Nicole Race

Graduate Theses and Dissertations

It is necessary to better serve justice to understand the mechanisms behind eyewitness identification and reports of confidence. The material contained within attempt to fit eyewitness identification to a diffusion model of processing, RTCON (Ratcliff & Starns, 2009). Participants saw eight mock crime videos and were then tasked with using eight showups or eight lineups to identify the suspects within the video. Half of the presentations were target present and half were target absent. Additionally, participants were either presented with biased or unbiased instructions. Strangely, unbiased lineups led to higher hit rates which is contrary to most findings in the …

Examining Psychologists’ Competence And Cultural Adaptations In Therapy When Working With Latina/O Clients, Marisela Lopez

Theses and Dissertations

The following multiple case study used semi-structured qualitative interviews and quantitative data to examine the multicultural competencies and cultural adaptations of four psychologists during a mock therapy session. This study consisted of three components: (1) Pre-Task, a semi-structured interview; (2) Task, each participant completing a mock therapy session with the same mock client and; (3) Post-Task, followed the client sessions and consisted of a semi-structured interview, a demographic questionnaire and two paper-pencil self-report measures. Immediately after each therapy session with the participants, the mock client completed two paper-pencil measures and a brief semi-structured interview about the participants. Three multicultural psychology …

Secular But Not Superficial : An Overlooked Nonreligious/Nonspiritual Identity., Daniel G. Delaney

Electronic Theses and Dissertations

Since Durkheim’s characterization of the sacred and profane as “antagonistic rivals,” the strict dichotomy has been framed in such a way that “being religious” evokes images of a life filled with profound meaning and value, while “being secular” evokes images of a meaningless, self-centered, superficial life, often characterized by materialistic consumerism and the cold, heartless environment of corporate greed. Consequently, to identify as “neither religious nor spiritual” runs the risk of being stigmatized as superficial, untrustworthy, and immoral. Conflicts and confusions encountered in the process of negotiating a nonreligious/nonspiritual identity, caused by the ambiguous nature of religious language, were explored …

The Effects Of Deception And Manipulation Of Motivation To Deceive On Event Related Potentials, Ethan C. Ashworth

Undergraduate Honors Theses

The Correct Response Negativity (CRN) is an event-related potential component that is affected by the act of deception. However, there have been inconsistent findings on the effect of deception on the CRN. Suchotzki, et al. (2015) suggested that the design of the paradigm used to elicit the deceptive response is what controls the size of the CRN. Specifically, motivation to deceive changes the size of deception relative to telling the truth. This study attempted to follow up on suggestions made by Suchotzki et al. (2015) to investigate if extraneous motivation to lie does indeed invert the ratio of CRN in …

The Effects Of Time Of Day And Circadian Rhythm On Performance During Variable Levels Of Cognitive Workload, Kathryn A. Feltman

Theses and Dissertations

The present study examined the effects of time of day of testing on a simulated aviation task. The tasks required the participants to engage in multitasking while electroencephalogram (EEG) data was collected to objectively measure participants’ workload. Task demands were altered throughout the testing period to expose participants to both high and low workload conditions. Additionally, individual differences in circadian rhythm were explored by assessing participants’ circadian typology. No significant differences in performance were found resulting from time of day differences. However, performance and EEG differences were found based on phase of testing and workload manipulations. Subjective workload measures were …

Correspondence Between Haptic And Visual Perception Of Stand-On-Ability: Do Hills Look As Steep As They Feel?, Jonathan Kenealy Doyon

Master's Theses

Vision and haptics play a central role in perceiving environmental layout to guide action. Hajnal, Wagman, Doyon, and Clark (2016) demonstrated that visual perception of stand-on-ability is accurate compared to action capabilities, whereas haptic perception of stand-on-ability reliably underestimates action capabilities. This finding contradicts Gibson’s (1979) theory of equivalence in perceptual systems, which suggests that perception should be equivalent regardless of modality. Previous comparisons of visual and haptic perception tested the modalities in isolation. The current experiment directly compares visual to haptic perception of stand-on-ability by using one perceptual system to estimate the other. Observers viewed a surface set to …

Hands, And Numbers, And Dots Oh My! Examining The Effect Of Nearby-Hands On Counting And Subitizing, Gabriel Allred

UNLV Theses, Dissertations, Professional Papers, and Capstones

The “nearby-hand” effect (Tseng, Bridgeman, & Juan 2012), an alteration of performance caused by the presence of our hands in the visuospatial area, has been found in learning, attention, and working memory tasks (Brockmole, Davoli, Abrams, & Witt, 2013a). However, no work to date has been published demonstrating a relationship between the nearby-hand effect and judgments of magnitude, including subitizing and counting. It is suggested by Tseng, Bridgeman, and Juan (2012) that nearby-hands affect attentional disengagement, yet little experimental evidence is available to support this notion. Given the serialized nature of counting, which requires attentional disengagement from item to item …

The Effect Of Gender, Not Math Anxiety, On Working Memory Tasks, Amy J. Mcauley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Math anxiety is defined as “feelings of tension and anxiety that interfere with the manipulation of numbers and the solving of mathematical problems in a wide variety of ordinary life and academic situations.” (Richardson & Suinn, 1972). The effects math anxiety has on various tasks are overwhelming. Math anxiety has been shown to relate to poor educational attainment and avoidance of math courses (Hembree 1990). Research has shown that math anxiety can affect simple process like counting (Maloney, Risko, Ansari, & Fugelsang, 2010) to taxing working memory while solving a math problem (Ashcraft & Kirk, 2001). Additionally, gender also plays …

The Relationship Between P300 Evoked Potentials And Prefrontal Cortex Oxygen Use: A Combined Eeg And Nirs Study, Will S. Rizer

All NMU Master's Theses

The P300 subcomponent, P3b, is an event related potential detected at the scalp surface when a working memory comparison results in differences between the contents of working memory and incoming stimulus information. Previous research has indicated that as infrequent targets become more difficult to detect (morphologically similar to a frequent non-target stimulus) the P300 becomes attenuated. fMRI research has also indicated increased prefrontal cortex (PFC) activity during P300 generation. To examine the relationship between P3b amplitude and PFC activity participants performed an easy and difficult target detection task in both EEG and NIRS called the oddball. The EEG and behavioral …

Testing A Model Based Approach To Selective And Flexible Attention, Anastasia Nicole Kerr-German

Masters Theses

A recent neural-process approach using dynamic field theory (DFT), put forth by Buss and Spencer (2014), demonstrated how a simple dimensional attention mechanism can explain the behavioral and neural data associated with the development of flexible attention and performance in the Dimensional Change Card Sorting task (DCCS). Taking a dynamical systems approach to the development of attention in executive functioning is critical as it allows us to further probe the underlying processes and mechanisms that give rise to later life success.

The goal of the current proposal is to generalize DFT in order to explain the development of selective attention …

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 …

The Effect Of Interruptions On Primary Task Performance In Safety-Critical Environments, Cheryl Ann Nicholas

Doctoral Dissertations

Safety critical systems in medicine utilize alarms to signal potentially life threatening situations to professionals and patients. In particular, in the medical field multiple alarms from equipment are activated daily and often simultaneously. There are a number of alarms which require caregivers to take breaks in complex, primary tasks to attend to the interruption task which is signaled by the alarm. The motivation for this research is the knowledge that, in general, interrupting tasks can have a potentially negative impact on performance and outcomes of the primary task. The focus of this research is on the effect of an interrupting …

Individual Differences In Stress And Coping: Testing A Model Of Decisional Control, Bryan D. Grant

Electronic Thesis and Dissertation Repository

Quantifying the processes of coping is one way to make the concept both descriptive and testable. Decisional Control (DC) is a formal, mathematically-specified, normative model which prescribes that an individual faced with a variety of alternatives in a stressing situation will attempt to minimize objective and perceived threat of an adverse event inherent within their choices. In this study, a game-theoretic probability mixture model created for DC was evaluated using established indexes of model fit to empirical decision and choice data. Sources of empirical departure from the fully normative model predictions, notably individual and group cognitive mapping of choice linked …

The Impact Of Balance Disturbance On Cognition, Erin Quasney

Dissertations (1934 -)

There have been remarkable gains within the scientific literature over the last few decades contributing to our understanding of the sequelae, recovery, and treatment of mild traumatic brain injury (mTBI), yet our knowledge of relationships among symptoms remains elementary in comparison. Cognitive and balance deficits are two of the most prevalent consequence of mTBI. There is some indication that a challenge to one or both of these functions can result in cognitive detriments due to constraints on attentional capacity. However, the evidence remains both conflicting and sparse. This study examined the impact of increasing balance challenge on attention and working …

The Discursive Functioning Of Knowledge Claims In Research Studies On Children’S Conceptual Knowledge Of Number, Patrick D. Byers

Dissertations, Theses, and Capstone Projects

Researchers interested in the development of conceptual knowledge of number have studied children’s behavior in various tasks or other contexts in order to draw conclusions about what they know. The guiding assumption of this work is that the presence or absence of a given form of knowledge is typically reflected in the ability/inability to perform certain types of behavior. Researchers complicate this assumption when they claim that (1) the ability to perform a given behavior may also reflect simple imitation or rote learning in the absence of understanding, and/or (2) that the inability to perform a certain behavior may reflect …

The Effects Of Alpha Oscillations On Touch Perception And Visuo-Tactile Integration, Lei Ai

Dissertations, Theses, and Capstone Projects

Previous studies have shown that touch perception and visuo-tactile integration have large inter-subject/intra-subject variations. For example, touch perception varies across trials and the temporal binding windows of visuo-tactile integration varies across subjects. I hypothesized that the variations might be due to the change of power, phase and peak frequency of brain alpha oscillations. In the first set of experiments, I examined whether the power and phase of alpha oscillations predict successful conscious touch perception. Near-threshold tactile stimuli were applied to the left hand while electroencephalographic (EEG) activity and fast signal optical imaging were recorded over the somatosensory cortex. Alpha power …

Observational Assessment Of Empathy In Parent-Child Verbal Exchanges And Their Influence On Child Behavior, Patty Carambot

Dissertations, Theses, and Capstone Projects

Empathy, the ability to both experientially share in and understand others’ thoughts, behaviors, and feelings, is vital for human adaptation. Deficits in empathy development have implications across the lifespan for the development of prosocial behavior, social functioning, mental health disorders, and risk for antisocial behavior (e.g., Guajardo, Snyder, & Petersen, 2009; Moreno, Klute & Robinson, 2008). In light of these societal and individual burdens, it is imperative to foster and strengthen the development of this ability early in life to prevent or ameliorate such negative outcomes. This type of prevention can take a variety of forms, but parent and child …

Cognitive And Affective Aspects Of Personality And Academic Procrastination: The Role Of Personal Agency, Flow, And Executive Function, Marc Graff

Dissertations, Theses, and Capstone Projects

Academic procrastination is a prevalent issue that affects school-related and other experiences of many students, with some studies identifying as many as a third of college students sampled as‘severe’ procrastinators. This study investigated some of the factors previous studies have identified as potential contributors to procrastinating in the academic arena. In defining procrastination as a self-regulation issue, it is proposed that distinct executive function processes play a role in one’s efforts at academic task engagement and completion and resisting the tendency to procrastinate on these tasks. It is also proposed that the frequency with which one experiences ‘flow’, a state …

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 …

Social Cognitive Processes In The Priming Of Mental Illness Stereotypes By The Media, Ginny Chan

Dissertations, Theses, and Capstone Projects

In high-profile violent incidents, there appears to be a disproportionate focus on the perpetrator’s mental health status in relation to the incident (Angermeyer & Matschinger, 1996). Several studies have highlighted the biased nature of the media in reporting news on mental illness and its negative impact on general consensus (Corrigan et al., 2013; Wahl, 1992, 2003). Researchers have also suggested that the media is a significant source of knowledge for the public (Jorm, 2000; Wahl, 2003). Based on a social cognitive perspective, pragmatic inference and stereotype priming provide a framework to understand the reader’s comprehension. The current studies aimed to …

Intraindividual Variability As A Predictor Of Cognitive Decline In Elderly, Wendy S. Ramratan

Dissertations, Theses, and Capstone Projects

Mild cognitive impairment (MCI) is conceptualized as a transitional state between normal aging and fully developed clinical features of dementia. The literature on MCI is notable for varied measurement approaches and lack of stability in the diagnostic entity, with many individuals remaining stable or reverting to normal cognitive status. Researchers agree that multiple neuropsychological domains should be assessed to enhance the assessment and prediction of cognitive decline. In addition, within-person assessments capture trajectories of decline, which are better suited for understanding individual change than simple comparison to group norms. The current study investigated the ability of within-person change on novel …

Native Language Adaptation To Novel Verb Argument Structures By Spanish-English Bilinguals: An Electrophysiological Investigation, Eve Higby

Dissertations, Theses, and Capstone Projects

Bilinguals have to learn two different grammatical systems. Some aspects of these grammars may be similar across the two languages (for example, the active-passive alternation) while others may exist in only one of the two grammars (for example, the distinction between recent and distant past). This dissertation investigates the degree to which grammar information specific to only one language is available when processing the other language. In particular, the current study focuses on the application of grammatical structures from the bilinguals’ second-learned language to their first-learned language, a direction of language transfer not often investigated. Based on a Shared Syntax …

Assessing The Impact Of Emotion In Dual Pathway Models Of Sensory Processing., James H. Kryklywy

Electronic Thesis and Dissertation Repository

In our daily environment, we are constantly encountering an endless stream of information which we must be able to sort and prioritize. Some of the features that influence this are the emotional nature of stimuli and the emotional context of events. Emotional information is often given preferential access to neurocognitive resources, including within sensory processing systems. Interestingly, both auditory and visual systems are divided into dual processing streams; a ventral object identity/perception stream and a dorsal object location/action stream. While effects of emotion on the ventral streams are relatively well defined, its effect on dorsal stream processes remains unclear.

The …
