The Roles Of Biophilic Attitudes And Auditory Stimuli Within Attention Restoration Theory, Jason B. Boggs

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attention Restoration Theory indicates that interacting with nature allows one’s fatigued, directed attention to be restored. This effect has been documented and produced through directed interaction with nature, such as a walk in the park, as well as through indirect interactions (e.g., photographs). The current dissertation was designed to: 1) investigate whether and how biophilic attitudes affect the attention-restoring effects incurred from interactions with nature, and 2) extend the research on ART by assessing the impact of nature-related audio stimuli. A total of 184 participants completed an assessment of biophilic attitudes, engaged in attention fatiguing exercises, and participated in one …

Novice Versus Expert Algebraic Problem-Solving Strategies: An Eye Tracking Approach, Krystal Kamekona-Mendoza

UNLV Theses, Dissertations, Professional Papers, and Capstones

Algebra continues to be an important point along the educational spectrum. It is often the point at which we see a deviation of educational trajectories for those who are interested in pursuing additional math and science courses and those who are not. Understanding how college algebra students perform is a crucial step in further understanding the difficulties that students often encounter, as well as understanding other potential factors that may contribute to their performance. The novice/expert paradigm is one way to examine performance differences. While existing literature indicates that novices and experts perceive, sort, and solve problems differently across a …

How Instruction, Math Anxiety, And Math Achievement Affect Learning A Novel Math Task: Evidence For Better Instruction, Amy Jane Mcauley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary goal of this paper is to test how math anxiety, achievement, and instruction affect learning a novel math task. Currently, most research measures achievement and math anxiety on previously learned tasks. A two-part study was proposed to measure the effects of math anxiety on learning modular arithmetic (MA), a novel math task that involves subtraction and division. Participants of varying degrees of anxiety and achievement were randomly assigned to either a specific or vague instruction condition. Participants were either taught how to solve the task or given minimal information about how to solve the task. Before moving on, …

The Effect Of Talker And Contextual Variability On Memory For Words In Sentences, Nichole Runge

Arts & Sciences Electronic Theses and Dissertations

Previous research has found that adding different forms of variability during study can affect later memory at test. For example, having words spoken by different talkers has been shown to improve recall of known and novel words (Goldinger et al., 1999; Barcroft & Sommers, 2005), and varying the cues in cue-target related word pairs has been found to improve recall of the targets (Glenberg, 1979; Bevan et al., 1966). It was unclear, however, whether benefits of variability would extend to more naturalistic stimuli, such as sentences, which have higher working memory demands. The present set of experiments investigated how talker …

The Effects Of Proficiency And Task Context On L2-L1 Noncognate Masked Translation Priming In Chinese-English Bilinguals, Mark J. Mcphedran

Electronic Thesis and Dissertation Repository

The masked translation priming effect was examined in Chinese-English bilinguals using three experimental paradigms: lexical decision, semantic categorization, and speeded episodic recognition. A machine-learning approach was used to assess the subject- and item-specific factors that contribute to the sizes of translation priming effects across these tasks. The factors that contributed to translation priming effects were found to be task specific. Priming effects in lexical decision were associated with higher self-rated listening and writing abilities in English, especially when primes were high-frequency and targets were low-frequency. Priming effects in semantic categorization were associated with more frequent use of English in daily …

The Effects Of Semantic Priming On Lexical Processing, Alexander Taikh

Electronic Thesis and Dissertation Repository

The present experiments were designed to investigate the locus of the semantic priming effect, a phenomenon that has received much research attention. Semantically related primes (e.g., cat) might activate the lexical representations of their targets (e.g., DOG) through automatic spreading activation at short stimulus onset asynchronies (SOAs) between the prime and target, or through generation of words expected to follow the prime at long SOAs. Alternately, semantically related primes might be used strategically to aid responding after target identification. The effects of masked orthographic primes (e.g., judpe-JUDGE), in contrast, are assumed to be strictly lexical and automatic. Lexical processing of …

Circumventing Spatio-Numeric Biases Through Non-Numeric Assessments Of Perceived Causal Strength, Daniel William Czarnowski

Seton Hall University Dissertations and Theses (ETDs)

Knowledge of cause and effect allows individuals to meaningfully interpret the events they perceive in the world, and the understanding of causality is thought to be grounded in the understanding of forces (Wolf, Ritter, & Holmes, 2014). Previous research has linked handedness with both the ability to exert force (e.g., Linkenauger et al., 2005) and causal learning (e.g., Goedert & Czarnowski, 2017). Historically, number lines have been used to assess causality, but because handedness has a strong spatial element, SNARC effects may influence judgments (Fias, 1996). The current experiment replicates previous work by Goedert and Czarnowski (2017) but changes the …

Conceptual Representation In Bilinguals: A Feature-Based Approach, Eriko Matsuki

Electronic Thesis and Dissertation Repository

A challenge for bilinguals is that translation equivalent words often do not convey exactly the same conceptual information. A bilingual exhibits a “semantic accent” when they comprehend or use a word in one language in a way that is influenced by knowledge of its translation equivalent. Semantic accents are well-captured by feature-based models, such as the Distributed Conceptual Feature model and the Shared (Distributed) Asymmetrical model, however, few empirical studies have used semantic features to provide direct evidence for these models. The goal of this thesis is to use a feature-based approach to identify conceptual differences in translation equivalent words …

Lexical Retrieval Inhibition From Semantically Related Retrieval Primes, Abhilasha Ashok Kumar

Arts & Sciences Electronic Theses and Dissertations

The phenomenological experience of lexical retrieval involves conscious and active attempts to retrieve semantically related information, but the direct influence of this retrieval process on subsequent retrieval is presently unknown. We investigated the influence of passively viewing or actively retrieving different types of information at the critical moment preceding lexical retrieval through a novel priming paradigm. Participants attempted to retrieve target words (e.g., FOLIAGE) from their low-frequency definitions or descriptions (e.g., the leafy parts of a plant or tree, collectively). Across five experiments, target retrieval was preceded by the brief presentation of a prime word (Experiment 1), progressive demasking of …

The Consequences Of Processing Of Goal-Irrelevant Information During The Stroop Task In Younger And Older Adults, Jessica Nicosia

Arts & Sciences Electronic Theses and Dissertations

Recent evidence from memory paradigms indicates that older adults can sometimes benefit more from processing goal-irrelevant information than younger adults, however these studies have often failed to simultaneously provide evidence of age-related control deficits. In the present experiments, participants initially studied a list of words. They then received a color-naming Stroop task where neutral words were either previously studied or new words. Across three experiments, participants were given different types of memory tests to examine the lingering effects of the neutral words during color-naming in younger and older adults. The results from all three experiments (including an attempted replication study) …

The Effect Of Changing Appraisals Of Current Life Success On Memories Of Love Towards Parents, Mario Herrera

Master's Theses

As we experience successes and failures in life, do we bias our memories of childhood? Cognitive appraisal theory would predict that emotions are elicited based on the current appraisal of an event or person. There is some research that these current appraisals can also distort memories of emotions surrounding an event. No past research has investigated whether current appraisal of life success would affect important autobiographical memories. Here, we examine the effects on childhood memory of love felt towards parents. Due to current appraisal theory, we expected memory of love towards parents would be prone to distortion and bias. We …

Values Vs. Self-Interest As Determinants Of Attitudes: Through A Construal Level Theory Lens, (Sometimes) Self-Interest Wins, Austin D. Eubanks

Graduate Theses and Dissertations

The present study (n = 335) attempted to conceptually replicate Hunt, Kim, Borgida, and Chaiken (2010) with a high-powered design to investigate whether values and self-interest differentially impact attitudes depending on psychological distance. Participants were assigned to complete a task that made self- or other-focused values more accessible, then indicated their attitudes about a student fee increase at a university to fund scholarships the participants would not be eligible to receive (thus going against their own financial self-interest for the well being of someone else). The memo describing the fee increase was manipulated such that the increase would be occurring …

The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg

Graduate Theses and Dissertations

Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents, yet have difficulty distinguishing between phonetically similar accents (Wagner, Clopper, & Pate, 2013). The present study aimed to determine whether the presence of dialect-specific vocabulary enhances young children’s ability to categorize speakers. Participants completed four training trials in which they were familiarized with photos of two children: one of whom used American English labels for test objects and one of whom used British English labels. After training trials, participants completed eight test trials in which they were asked to infer which target child would use …

The Cognitive Psychology Of Humour In Written Puns, James Boylan

Electronic Thesis and Dissertation Repository

The primary purpose of this dissertation was to investigate how humour from written puns is produced. Prior models have emphasized that novel or surprising incongruities should be important to humour appreciation­ (Suls, 1972; Topolinski, 2014). In study 1, a new approach to operationalizing incongruity as semantic dissimilarity was developed and tested using Latent Semantic Analysis (Landauer, Foltz & Laham, 1998). “Latent semantic incongruity” was associated with humour ratings, but only for puns with low ratings of familiarity from a prior occasion or for those with a low level of aggressive content. Overall, there was also an unexpected strong positive association …

Semantic Processing Of Nominal Metaphor: Figurative Abstraction And Embodied Simulation, Hamad Al-Azary

Electronic Thesis and Dissertation Repository

In a metaphor such as that lawyer is a shark, the concept lawyer, which is the metaphor topic, and the concept shark, which is the metaphor vehicle, interact to produce a figurative meaning such that lawyers are predatory. Some theorists argue that sensorimotor properties of the vehicle are the basis of metaphor comprehension (Gibbs & Matlock, 2008; Paivio, 1979; Wilson & Gibbs, 2007). As such, that lawyer is a shark is processed by an embodied simulation where sensorimotor imagery associated with sharks is simulated (e.g., sharks hunting in deep water). However, the long-standing assumption is that metaphors are …

Motivation Predicts Self-Control Of Racial Bias After Viewing Alcohol Advertisements, Zachary Wolfgang Petzel

Dissertations

Exerting self-control shifts motivation toward rewarding cues (i.e., approach motivation) and impairs control of racial bias. However, whether approach motivation predicts deficits in control of racial bias is unknown. Exertion of self-control is also related to alcohol use, but whether exerting self-control shifts motivation toward alcohol-related cues is not established. Similar to exerting self-control, viewing alcohol-related cues shifts motivation and promotes racial bias. The current study examined the interaction between exerting self-control and viewing alcohol-related cues on approach motivation and its influence on racial bias. Participants (N = 71) exerted (or did not exert) self-control and then viewed neutral …

Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan

Doctoral Dissertations

In face-to-face conversations, listeners process and combine speech information obtained from hearing and seeing the speaker talk. Audiovisual speech typically leads to more robust recognition of speech, as it provides more information for recognition but also as it helps listeners adjust to speaker idiosyncrasies. The goal of the current thesis was to examine how certain perceptual and cognitive factors modulate how listeners use visual speech to facilitate momentary speech perception and to adjust to a speaker’s idiosyncrasies. Results showed that (older) listeners’ sensitivity to cross-modal synchrony is related to the size of the audiovisual interactions during early perceptual processing. Furthermore, …

The Effects Of Reward And Risk Level Associated With Speeded Actions: Evidence From Behavior And Electroencephalography, Xingjie Chen

Masters Theses

Choosing a course of action in our daily lives requires an accurate assessment of the associated risks as well as the potential rewards. The present two studies investigated the mechanism of how reward and risk level influence the motor decisions of speeded actions (Chapter 2) and its neural dynamics (Chapter 3) by focusing on the beta band (15-30 Hz) oscillation patterns reflected in the EEG signals. Participants performed a modified version of the Go-NoGo task, in which they earned reward points based on the speed and accuracy of response. On each trial, the reward points at stake (120 vs. 6) …

Visual And Verbal Serial List Learning In Patients With Statistically-Determined Mild Cognitive Impairment, Victor J. Wasserman

Theses and Dissertations

Objective: To compare verbal versus visual serial list learning test performance in mild cognitive impairment (MCI) and assess relationships between serial list learning and hippocampal volume. Methods: Patients were diagnosed with non-MCI, amnestic MCI (aMCI), and combined mixed/dysexecutive MCI (mixed/dysMCI). Outcome measures included immediate/delay free recall, and delay recognition performance from the 12-word Philadelphia Verbal Learning Test (PrVLT) and the Brief Visuospatial Memory Test-Revised (BVMT-R). Lateral hippocampal volumes were obtained. Results: Non-MCI patients scored better than other groups on P(r)VLT immediate/delay free recall. aMCI patients scored lower than other groups on P(r)VLT delay recognition. Non-MCI patients were …

Validation Of The Barkley Deficits Of Executive Functioning Scale-Short Form, Brian Sheble

Dissertations

The Barkley Deficits of Executive Functioning-Short Form (BDEFS-SF) is a short rating scale measuring executive functioning in adults. The BDEFS-SF was developed using the 5 highest loading questions from the BDEFS-LF. Consequently, the psychometric qualities of the BDEFS-SF were not investigated using formal methods. In this study, the psychometric attributes of the BDEFS-SF were examined using two separate but similar groups. The first group of 264 men and women aged 18-35 years old completed the BDEFS-SF via an internet survey. The second group of 36 men and women aged 18-35 years old completed the BDEFS-SF and individualized assessments of executive …

The Efficacy Of School Implemented Cognitive Behavioral Therapy To Reduce Adolescent Anxiety, Madeline N. Michelsen

Selected Honors Theses

Adolescent anxiety is a growing problem which affects millions of children every year. There are a myriad of factors which produce adolescent anxiety such as excessive stress, adverse childhood experiences, and chemical imbalances amongst many other factors. An emerging therapy to treat mental health disorders, such as anxiety, is cognitive behavior therapy (CBT) which teaches participants how to correct maladaptive thought patterns to develop resilience. Cognitive behavior therapy has produced positive results for reducing symptoms of anxiety and other mental health disorders in both adolescents and adults. Due to its unparalleled student access, schools have the unique opportunity to develop …

A Functional Neuroimaging Study Of Self-Regulatory Control In Adults With Gambling And Obsessive-Compulsive Disorders, Nidhi Parashar

Dissertations, Theses, and Capstone Projects

Objective: Recent findings suggest phenomenological similarities across gambling and obsessive-compulsive disorders. The key similarity between the disorders is the failure to inhibit or control a repetitive behavior (or urges to engage in a behavior) and intrusive thoughts. Our current understanding of the neural pathophysiological mechanisms linking gambling and obsessive-compulsive disorders is limited. Thus, the aim of the present study was to examine the functioning of frontostriatal brain regions that support self-regulatory control in adults with gambling and obsessive-compulsive disorders.

Methods: The study compared functional magnetic resonance imaging blood oxygen level dependent response in 19 adults with pathological gambling (PG), …

Threat-Related Attentional Bias In Relation To Anxiety And Depressive Symptoms In The General Population: The Potential Role Of Sex Effects, Beril Yaffe

Dissertations, Theses, and Capstone Projects

Heightened sensitivity to relevant environmental stimuli (attentional bias) has been observed in relation to clinical and non-clinical anxiety and depression symptoms. While depression symptoms are associated with sensitivity to disorder and self-relevant words, hypervigilance to threatening stimuli is observed in relation to anxiety symptoms. Furthermore, attentional bias has been shown to play an important role in the development and maintenance of depressive and anxiety disorders. Accordingly, a large body of literature has examined threat-related attentional bias in relation to symptoms of anxiety and depression. However, several methodological inconsistencies exist across studies, including variability in definitions of threat, lack of consideration …

Manipulating Goal States And Brain States: Using Eeg And Hd-Tdcs To Investigate Mechanisms Underlying The Influence Of Achievement Goals On Declarative Memory, Yuliya Ochakovskaya

Dissertations, Theses, and Capstone Projects

When it comes to learning factual information, students may benefit from having opportunities where they can learn from their mistakes as opposed to only being asked to study that information. However, the achievement goals that instructors set for their students may influence how students engage with these learning opportunities. Although some instructors may focus students on learning (i.e. mastery goals), others may seek to motivate students by focusing them on doing better than others (i.e. performance goals), which is thought promote greater sensitivity to errors and impair learning. Across two studies, the present dissertation examined the roles of dorsolateral frontal …

The Relationship Between Cognitive And Neural Bases Of Metamemory Judgments, Alexandra M. Gaynor

Dissertations, Theses, and Capstone Projects

Metamemory monitoring, the process of making subjective assessments of the status of one’s own memory, is crucial to guiding behavior and effective learning. Past cognitive research has shown that subjective confidence judgments are inferential in nature, and based on cues available at the time of the judgment. When confidence is based on cues that are related to objective memory performance, metamemory accuracy is high. However, past studies have shown that metamemory monitoring tends to be inaccurate because individuals base their confidence on information that is not predictive of memory success, such as the fluency with which items were encoded during …

Rumination And Rebound From Failure: Investigating How Trait And State Forms Of Ruminative Thought Influence Attention To Errors And The Ability To Correct Them In A Challenging Academic Environment, Ronald C. Whiteman

Dissertations, Theses, and Capstone Projects

Rumination is a recurrent and repetitive manner of thinking that can be triggered by blockage of personally-relevant goals, creating a temporary state of abstract and evaluative self-focus that can also become a chronic trait-like style of responding to personal challenges. Despite claims that rumination helps down-regulate unwanted emotion, cope with problems, and lead to goal attainment, it often increases negative affect, interferes with problem solving, and exacerbates goal-state discrepancies, particularly for women. Given the pervasiveness of rumination and its potential impact on cognitive processes and emotional states, one important yet untested question is how it might impact individuals’ ability to …

The Effects Of Perceptual Fluency On Emotional Word Recognition, Joseph M. Nidel

Electronic Thesis and Dissertation Repository

To investigate if making a word harder to read attenuates emotional influences like valence and arousal, we used a sample of Warriner and colleagues’ (2013) corpus with valence and arousal norms, a font manipulation from the perceptual fluency paradigm, and a word naming task. We found that, contrary to our hypotheses, emotional influences of words on RT were not attenuated in the disfluent condition; in fact, disfluency seemed to amplify the facilitative effects of high arousal. These results suggest that models of word recognition should consider the role that emotions play in recognition. They also provide limited support to models …

Characterizing The Cognitive And Emotional Effects Of Delta-9-Tetrahydrocannabinol In Distinct Hippocampal Sub-Regions, Dinat Khan

Electronic Thesis and Dissertation Repository

The objective of this study is to determine the potential differential effects of THC in the DH or VH sub-regions, as well as the upstream effects on PFC neuronal activity and oscillations. Rodents used for electrophysiology were infused with THC or vehicle in the DH or VH regions, combined with PFC recordings. Additionally, a battery of behavioural paradigms was performed. Deficits in short-term memory when THC was infused into both regions was observed, however working memory was impaired with VH infusions only. This could be due to THC-induced dysregulation in the PFC, as beta oscillations were significantly decreased selectively in …

Ipad Use To Enhance Conversations Between Persons With Dementia And Their Family Caregivers, Kelsey Dynes

Electronic Thesis and Dissertation Repository

Electronic conversational memory notebooks, a more current application of previous hardcopy versions, consist of personally relevant photographs and accompanying sentences. The notebooks help persons with dementia access memories during conversations. Person-centred communication (PCC) recognizes the individual, accommodating for personal beliefs and intentions. The purpose of the current study was to determine whether persons with dementia and their family caregivers could be educated and trained to use PCC while using an iPad-based electronic conversational memory notebook. Seven persons with mild to moderate dementia and their family caregiver completed the six-week study. Participants were educated and trained to use PCC while conversing …
