Support For Gestalt Versus Business-As-Usual Theories Of Insight Depends On Operational Definition Of Insight, Kimberly D. Lee

Psychology Theses & Dissertations

Some theories propose that insight involves automatic processes that are responsible for restructuring. Other theories postulate that the mechanisms surrounding restructuring are controlled and effortful. The current study tested these theories by comparing different methodology and operational definitions that have been used in previous research to investigate the nature of “Aha!” experiences and impasse in insightful problem solving. One hundred two undergraduate psychology students from Old Dominion University completed working memory tasks, six classic insight problems, and gave initial problem representation ratings for the insight problems before solution attempt. Using a think-aloud protocol, we assessed the occurrence of impasse during …

Roles Of Shifting Attention, Alternating Attention And Inhibition On Temporary Syntactic Ambiguity Resolution And Use Of Context In Younger And Older Adults, Youngmi Park

Dissertations, Theses, and Capstone Projects

Twenty-four younger adults (20-35 years, mean: 25.88) and thirty-four older adults (65-79 years, mean: 71.82) read sentences via a word-by-word self-paced reading paradigm. Study 1 examined how older and young adults resolve sentences containing Noun Phrase (NP) and Verb Phrase (VP)-attached Prepositional Phrases (PPs) yielding temporary syntactic ambiguity, and which cognitive factors (working memory capacity, inhibition, shifting attention, alternating attention, and cognitive processing speed) contribute to temporary syntactic ambiguity resolution.

Study 2 was designed to investigate how both age groups utilize contextual information while resolving PP-attachment, and which cognitive functions play a role in the use of referential context during …

Art As Communication: Employing Gricean Principles Of Communication As A Model For Art Appreciation, Melissa June Dolese

Dissertations, Theses, and Capstone Projects

Abstract

How and why artworks elicit varied preferences and judgments among different individuals remains a topic with many unresolved issues. For instance, individuals with little artistic experience tend to show little appreciation for abstract art, even though such works often show a highly skilled organization of visual elements. A key aspect of a positive aesthetic experience concerns the ability of viewers to construct meaning. I propose that viewers attempt to make meaning of artworks due to a sense that art is a communicative process. Here I attempt an application of one intentionalist model of communication, the Gricean framework, to visual …

Variability, Stability, And Flexibility In The Speech Kinematics And Acoustics Of Adults Who Do And Do Not Stutter, Eric S. Jackson

Dissertations, Theses, and Capstone Projects

It is well known that people who do and do not stutter produce speech differently, at least some of the time, even when perceived as fluent. One way that investigators have assessed these differences is by measuring variability, or the inconsistency of repeated speech movements. Variability in speech has typically been quantified using linear analysis techniques (e.g., measures of central tendency), and results have indicated that people who stutter produce speech that is (sometimes) characterized by increased variability. However, variability is a complex phenomenon, one that cannot be assessed by linear methods alone. This dissertation employs linear and nonlinear analysis …

The Role Of Posterior Parietal Cortex In Episodic Memory Retrieval: Transcranial Direct Current Stimulation Studies (Tdcs), Denise Pergolizzi

Dissertations, Theses, and Capstone Projects

Neuroimaging studies of recognition memory have shown that greater activity in the lateral posterior parietal cortex (PPC) correlates with successful recognition in a variety of paradigms, but experimental techniques that manipulate brain activity are necessary to determine the specific contribution of the PPC in episodic memory retrieval. Transcranial Direct Current Stimulation (tDCS) is a non-invasive technique that can be used to manipulate cortical excitability. The collection of experiments that comprise this dissertation use tDCS to determine: 1) whether or not the lateral PPC is causally involved in episodic retrieval, and 2) whether the lateral PPC has a direct role in …

Effects Of Nicotine On A Translational Model Of Working Memory, David Alderson Macqueen

USF Tampa Graduate Theses and Dissertations

Cognitive research with human non-smokers has demonstrated that nicotine generally enhances performance on tasks of attention but, working memory does not appear to be affected. In contrast, nicotine has been shown to produce robust enhancements of working memory in non-human animals. To address this disparity, the present study investigated the effects of nicotine (2mg, 4mg nicotine gum, and placebo) on the performance of 30 non-smokers (15 male) completing a working memory task developed for rodents (the odor span task, OST). Nicotine has been reported to enhance OST performance in rodents and the present study sought to determine whether the effect …

Modeling Sources Of Teaching Self-Efficacy For Science, Technology, Engineering, And Mathematics Graduate Teaching Assistants, Sue Ellen Dechenne, Natalie A. Koziol, Mark Needham, Larry Enochs

Department of Educational Psychology: Faculty Publications

Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor’s belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs …

Medulla: A 2d Sidescrolling Platformer Game That Teaches Basic Brain Structure And Function, Joey R. Fanfarelli, Stephanie Vie

Faculty Scholarship and Creative Works

This article explores the design and instructional effectiveness of Medulla, an educational game meant to teach brain structure and function to undergraduate psychology students. Developed in the retro-style platformer genre, Medulla uses two-dimensional gameplay with pixel-based graphics to engage students in learning content related to the brain, information which is often pre-requisite to more rigorous psychological study. A pretest posttest design was used in an experiment assessing Medulla’s ability to teach psychology content. Results indicated content knowledge was significantly higher on the posttest than the pretest, with a large effect size. Medulla appears to be an effective learning tool. These …

Distance Effects In Similarity Based Free Categorization, Benjamin Alan Miller

Electronic Theses, Projects, and Dissertations

This experiment investigated the processes underlying similarity-based free categorization. Of particular interest was how temporal distance between similar objects affects the likelihood that people will put them into the same novel category. Participants engaged in a free categorization task referred to as binomial labeling. This task required participants to generate a two-part label (A1, B1, C1, etc.) indicating family (superordinate) and species (subordinate) levels of categorization for each object in a visual display. Participants were shown the objects one at a time in a sequential presentation; after labeling each object, they were asked to describe the similarity between that …

Toward A Two-Stage Model Of Free Categorization, Gregory J. Smith

Electronic Theses, Projects, and Dissertations

This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

Partner's Understanding Of Affective-Cognitive Meta-Bases Predicts Relationship Quality, Kenneth Tan, Ya Hui Michelle See, Christopher R. Agnew

Research Collection School of Social Sciences

Knowledge that partners have about each other's attitudes are consequential for relationship quality. This article extends prior research and examines whether knowledge regarding a partner's meta-attitudinal bases, or subjective perceptions of how one's attitudes are driven, can influence relationship quality. Given how meta-bases are reflective of information-processing goals, we hypothesized that partner understanding of meta-attitudinal bases would positively predict relationship quality. Self and partner ratings of how relationally relevant attitudes were driven, as well as perceptions of relationship quality, were assessed. Results revealed that a partner's knowledge of one's meta-bases positively predicts one's own reported relationship quality. Results remained significant …

Building Metamemorial Knowledge Over Time: Insights From Eye Tracking About The Bases Of Feeling-Of-Knowing And Confidence Judgements, Elizabeth F. Chua, Lisa A. Solinger

Publications and Research

Metamemory processes depend on different factors across the learning and memory time-scale. In the laboratory, subjects are often asked to make prospective feeling-of-knowing (FOK) judgments about target retrievability, or are asked to make retrospective confidence judgments (RCJs) about the retrieved target. We examined distinct and shared contributors to metamemory judgments, and how they were built over time. Eye movements were monitored during a face-scene associative memory task. At test, participants viewed a studied scene, then rated their FOK that they would remember the associated face. This was followed by a forced choice recognition test and RCJs. FOK judgments were less …

Culture And Cognition: The Role Culture Plays In Cognitive Development In Rural Tanzania, Eileen Seissen

Capstone Collection

This capstone paper examines the perceived difference of cognition in a Tanzanian classroom. It also examines the effects culture has on cognition. It aims to answer the questions: What role does Tanzanian culture play in shaping the cognitive skills of its children? And, from an American trainers perspective, within an experiential learning environment, what cognitive differences are perceived in abstract thinking, creativity, critical thinking, and problem-solving? Nine American trainers, one Tanzanian trainer, and one Tanzanian student participated in my study. Each participant filled out a questionnaire geared toward understanding their training methods and perceptions of participant's skills and abilities. After …

A Descriptive Analysis Of The Appropriate Use Of Cognitive Bias Terminology In Forensic Science Literature, Courtney A. Winters, Evelyn M. Buday, Trevor I. Stamper

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cognitive bias occurs without a person’s awareness and can affect decision-making abilities. In forensic science, bias can be especially detrimental to making accurate decisions about the evidence in a criminal investigation. There are many academic studies in identifying, describing, and suggesting ways to mitigate cognitive biases in forensic science. Many authors will give a known cognitive science concept a new name or create their own bias. This is a problem in the literature because nobody knows for sure how many published studies are referring to or testing the same phenomena since authors are using different definitions or terminology to describe …

The Compensatory Role Of Implementation Intentions For Young Adults With Low Working Memory Capacity, J Thadeus Meeks, Margarida Pitães, Gene A. Brewer

SIUE Faculty Research, Scholarship, and Creative Activity

Many factors improve prospective memory performance both inside and outside of the laboratory, including the detailed planning of the situational cue and intended action (i.e., implementation intentions). In the current study, we obtained measures of working memory capacity and laboratory event-based prospective memory performance in college-aged adults. Half of our participants formed an implementation intention in the prospective memory task. Due to evidence that implementation intentions increase the encoding/retrieval efficiency of the prospective memory, it was predicted that forming an implementation intention would serve as a compensatory strategy for those with low working memory ability. Our results supported this hypothesis …

Adult Attachment Styles And Psychopathic Traits: A Relationship Mediated By Empathy And Emotional Regulation?, Chelsea Heim

USC Aiken Psychology Theses

Psychopathic personality traits encompass an array of characteristics that emerge early in life and are influenced by insecure attachments between children and their parents. Disruptions in parent-child interactions also affect the development of empathy (Panfile & Laible, 2010) and emotion regulation (Waters, S. F., Virmani, E. A., Thompson, R. A., Meyer, S., Raikes, H. A. & Jochem, R., 2010), which contributes to lasting impairments in interpersonal working models about the self and others (Mack, Hackney & Pile, 2010). The interactions between psychopathy and insecure attachment, low levels of empathy, and the ability to regulate one’s emotions have been separately investigated …

Phase Change Lines, Scale Breaks And Trend Lines Using Excel 2013Tm, Neil Deochand

Masters Theses

The development of graphing skills for the behavior analyst is an ongoing process. Specialized graphing software is often expensive, not widely disseminated, and may require specific training. Dixon, et al. (2009) provided an updated task analysis (Carr & Burkholder, 1998) in the widely used platform Excel 2007. Vanselow and Bourret (2012) provided online tutorials outlining some alternate methods also using Office 2007. This article serves as an update to those task analyses with alternative and under-utilized methods in Excel 2013. To examine the utility of our recommendations twelve psychology graduate students were presented with the task analyses and the experimenters …

The Effect Of Sleep On Perceptual Learning And Memory Consolidation, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

An ability to segregate speech accurately is essential given that most auditory environments contain other overlapping conversations or environmental noise. While perceiving speech among background noise can be difficult in and of itself, those with hearing impairments can experience considerable difficulty. While training has been shown to benefit perceptual segregation of trained sounds, it is unclear how such training transfers to sounds not included in a training regimen. The current study aimed to address this question by training listeners on a portion of sounds during a vowel segregation task, and subsequently testing on both the trained sounds and untrained sounds. …

Prefrontal Cortex Activity During Attentional Bias Conditioning With Fearful Faces: A Near-Infrared Spectroscopy Analysis, Robert D. Torrence

All NMU Master's Theses

Observing a fearful facial expression elicits an automatic orienting of attention. Past research focusing on fear conditioning has used an unconditioned stimulus that the participant directly experiences (e.g. shock). Other research has focused on observational fear learning where the participant watches another individual receive the stimulus. The aim of this study was to condition a colored square with a fearful face in the dot-probe task. Orienting toward and disengagement from fearful faces was also examined using the dot-probe task. In addition, hemodynamic responses in the prefrontal cortex (PFC) were measured using near-infrared spectroscopy (NIRS). It was hypothesized that after pairing …

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 …
