What Happened Last Night? Sleep, Sex, And Recollection, Amanda Gale Renfro Jan 2015

What Happened Last Night? Sleep, Sex, And Recollection, Amanda Gale Renfro

Online Theses and Dissertations

Previous research has repeatedly illustrated the beneficial influence of sleep on memory processes. Further, evidence has demonstrated the power of sexual valance to enhance memory for certain types of stimuli. The present study investigated the possible interaction effect between sleep and sexual valance on recollection memory in 44 undergraduate and graduate student participants at Eastern Kentucky University, based upon a method by Alger, Lau, & Fishbein (2012); however, in the current study, recollection memory items were words received audibly rather than visually. Behavioral data, electroencephalography (EEG), and skin conductance data was collected to assess memory performance, sleep progress, autonomic nervous …

Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman Jan 2015

Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman

Online Theses and Dissertations

The current proposed study examines a concept that has been looked at before but now using a new specific population. Previous research examined shows that reasons for motivation affect goal attainment and success. The current study is looking at how relational autonomous reasons for motivation play a role in goal attainment in athletes. Eastern Kentucky University athletes were administered a short questionnaire and their previous athletic performance was used as well. The two sets of data were then used to examine the relationship between the two variables. The results of the study showed a positive correlation between Relationally-Autonomous Reasons (RAR) …

Psychophysiological Markers Of Cognitive Reactions To Depictions Of Corporal Punishment, Hope Reuschel Jan 2015

Psychophysiological Markers Of Cognitive Reactions To Depictions Of Corporal Punishment, Hope Reuschel

Online Theses and Dissertations

The following study assessed cognitive mechanisms, via physiological measures, in reaction to photos depicting conditions of corporal punishment, nonphysical punishment, and a neutral control. Detections in skin conductance (SCR) were used to examine autonomic stress response. The current study examined executive working memory (WM) processes as influenced by cognitive and psychophysiological response to viewing depictions of various punishments being implemented. Results of this study found that while participants reacted differently, autonomically and cognitively, to photo conditions, these differences were unrelated to other anticipated moderators such as tendency to internalize shame or greater personal exposure to corporal punishment. Subsequent analyses, however, …

Equate: Observed-Score Linking And Equating In R, Anthony D. Albano Jan 2015

Equate: Observed-Score Linking And Equating In R, Anthony D. Albano

Department of Educational Psychology: Faculty Publications

Linking and equating are statistical procedures used to convert scores from one measurement scale to another. These procedures are most often used in testing programs that involve multiple test forms, where adjustments are made for form difficulty differences when creating a measurement scale that is common across forms. Linking and equating methods are traditionally distinguished by the type of scores they are applied to, whether observed scores or scores from an item response theory model. Methods are also distinguished by the study design under which measurements are taken. The R package equate (Albano, 2014) is free, open-source software for conducting …

Building An Adaptive Brain Across Development: Targets For Neurorehabilitation Must Begin In Infancy, Jamie O. Edgin, Caron A. C. Clark, Esha Massand, Annette Karmiloff-Smith Jan 2015

Building An Adaptive Brain Across Development: Targets For Neurorehabilitation Must Begin In Infancy, Jamie O. Edgin, Caron A. C. Clark, Esha Massand, Annette Karmiloff-Smith

Department of Educational Psychology: Faculty Publications

Much progress has been made toward behavioral and pharmacological intervention in intellectual disability, which was once thought too difficult to treat. Down syndrome (DS) research has shown rapid advances, and clinical trials are currently underway, with more on the horizon. Here, we review the literature on the emergent profile of cognitive development in DS, emphasizing that treatment approaches must consider how some “end state” impairments, such as language deficits, may develop from early alterations in neural systems beginning in infancy. Specifically, we highlight evidence suggesting that there are pre- and early postnatal alterations in brain structure and function in DS, …

Neural Responses To Truth Telling And Risk Propensity Under Asymmetric Information, Hideo Suzuki, Masaya Misaki, Frank Krueger, Jerzy Bodurka Jan 2015

Neural Responses To Truth Telling And Risk Propensity Under Asymmetric Information, Hideo Suzuki, Masaya Misaki, Frank Krueger, Jerzy Bodurka

Department of Educational Psychology: Faculty Publications

Trust is multi-dimensional because it can be characterized by subjective trust, trust antecedent, and behavioral trust. Previous research has investigated functional brain responses to subjective trust (e.g., a judgment of trustworthiness) or behavioral trust (e.g., decisions to trust) in perfect information, where all relevant information is available to all participants. In contrast, we conducted a novel examination of the patterns of functional brain activity to a trust antecedent, specifically truth telling, in asymmetric information, where one individual has more information than others, with the effect of varying risk propensity. We used functional magnetic resonance imaging (fMRI) and recruited 13 adults, …

Music, Andrea R. Halpern, Robert J. Zatorre Jan 2015

Music, Andrea R. Halpern, Robert J. Zatorre

Faculty Contributions to Books

Neuroimaging has contributed greatly to our understanding of the sensory, motor, and cognitive systems involved in musical processing. Cortical loops connecting auditory with parietal, premotor, and prefrontal cortices are important for encoding pitch and temporal relationships from which music is built and for generating musical expectancies. These circuits are also important for holding information in working memory and for interfacing perceptual and motor representations. Musical imagery recruits auditory areas together with frontal and supplementary motor regions. Musical emotion emerges from the interaction of these systems with the reward circuit. All of these systems are modifiable functionally and structurally following training.

Hypomania And The Effects Of Working Memory Load On Risk-Taking, Joseph B. Todd Jan 2015

Hypomania And The Effects Of Working Memory Load On Risk-Taking, Joseph B. Todd

College of Graduate Studies: Theses & Dissertations

Hypomania is an episodic mood state that closely resembles mania, and it is characterized by irritability, euphoria, racing thoughts, and impulsivity. The present study focuses on risk-taking, a behavioral manifestation of impulsivity, and the potential working memory mechanisms responsible for eliciting this behavior in people affected by hypomanic symptoms. Specifically, research suggests that taxing working memory accelerates the process by which individuals with high levels of hypomanic symptoms engage in risk-taking. The purpose of the current study was to examine the effects on hypomanic traits and working memory taxation on a behavioral measure of risk-taking. One hundred and forty-five participants …

Tornado Trouble: How Can Current Tornado Warnings Be Improved?, Jonathan P. Evans Jan 2015

Tornado Trouble: How Can Current Tornado Warnings Be Improved?, Jonathan P. Evans

College of Graduate Studies: Theses & Dissertations

There are many unnecessary deaths from tornadoes every year (NOAA.org, 2013). Although there have been great advancements in tornado warning systems (Coleman, Knupp, Spann, Elliot, & Peters, 2010), more changes to systems could be made to motivate people to take action in preparation for tornadoes (Brotzge & Donner, 2013). Protection motivation theory outlines the process by which we assess threats and decide whether or not preventative actions are worth performing. If the threat is perceived as severe enough and the preventative actions are seen as capable of mitigating the threat, the individual is motivated to act (Rogers, 2000). One means …

Learning Requires Attention For Binding Affective Reinforcement To Information Content, Chia Mun Foo Jan 2015

Learning Requires Attention For Binding Affective Reinforcement To Information Content, Chia Mun Foo

Scripps Senior Theses

Humans are limited in their capacity to process information about the environment; to choose the most salient details to process, we have to make rapid value appraisals and prioritize our attentional resources. In this proposed study, it is expected that attention is required to learn from affective information. Learning is measured by the difference between update (the difference between the first and second estimation) and the estimation error (the difference between the average likelihood and the first estimation). Using a belief-updating paradigm, participants will be asked to estimate their likelihood of encountering a negative event, once before and once after …

The Outer Limits Of Cognitive Processing: A Closer Look At What Is Desirable, Zachary K. Walter Jan 2015

The Outer Limits Of Cognitive Processing: A Closer Look At What Is Desirable, Zachary K. Walter

Undergraduate Honors Thesis Collection

Cognitive tasks are most satisfying when they include the right balance between ease and difficulty (Labroo & Kim, 2008). This balance is viewed as optimal for high quality and progressive learning in school and societal contexts (Bjork & Bjork, 1992). This idea is the basis of the concept of desirable difficulties, which are defined as certain difficulties in the learning process that can greatly improve long-term retention of learned material (Bjork & Bjork, 1992). Having received a lot of attention in recent research, they allow for one to develop questions about how we, as humans, approach certain tasks and where …

Emotion And Pain Effects On Tunnel Memory, Alexandra Nicolette Robinson-Norris Jan 2015

Emotion And Pain Effects On Tunnel Memory, Alexandra Nicolette Robinson-Norris

Undergraduate Honors Thesis Collection

Previous work by Andreano and Cahill (2006) has shown the Cold Pressor Stress (CPS) to enhance memory. A similar enhancement can occur with non-physical stressors. Puga & Bohannon (2013) found emotional slides to have an enhancing effect on preceding information. Although it is clear that physical and visual stressors can enhance memory, it is still unclear whether peripheral or central items are better remembered after arousing situations. Safer et al. (1998) suggested that during encoding, arousal creates a "tunnel memory" effect. Participants accurately remember central items but tend to disregard those in the periphery. The study focused on combined visual …

Hemispheric Specialization For Emotion Within First And Second Languages : Emotion Word Processing In Monolingual And Bilingual Speakers, Jennifer Mary Martin Jan 2015

Hemispheric Specialization For Emotion Within First And Second Languages : Emotion Word Processing In Monolingual And Bilingual Speakers, Jennifer Mary Martin

Legacy Theses & Dissertations (2009 - 2024)

Emotion representation in monolingual speakers is complex, and for bilinguals the relationship between emotion and language can be even more intriguing. The present study examined reactions to words of six types, including positive, negative, and neutral words varying in concreteness. Words and nonwords were intermixed in a lexical decision task using hemifield presentation. In Experiment 1, participants were English monolinguals and all stimuli were presented in English. In Experiment 2, participants were Spanish-English bilinguals who were presented with both English and Spanish stimuli. Results revealed a general left hemisphere advantage. Overall, reaction times for positive words were faster than for …

I Can See What You Are Saying : Auditory Labels Reduce Visual Search Times, Kit Wing Cho Jan 2015

I Can See What You Are Saying : Auditory Labels Reduce Visual Search Times, Kit Wing Cho

Legacy Theses & Dissertations (2009 - 2024)

The present study explored the mechanisms underlying the self-directed speech effect, the finding that relative to silent reading of a label (e.g., “DOG”), saying it aloud reduces visual search reaction times (RTs) for locating a target picture among distractors. Experiment 1 examined whether this effect is due to a confound in the differences in the number of cues in self-directed speech (two) vs. silent reading (one) and tested whether speech, per se, is required for the effect. Self-directed speech did not reduce search RTs more than hearing only a pre-recorded auditory presentation of a label, both of which reduced RTs …

Key Generalization Of Recognition Memory For Melodies, Abigail Lincoln Kleinsmith Jan 2015

Key Generalization Of Recognition Memory For Melodies, Abigail Lincoln Kleinsmith

Legacy Theses & Dissertations (2009 - 2024)

People easily recognize a melody in a previously unheard key, but they also retain some key-specific information. I tested the hypothesis that individuals compare novel melodies to a memory “prototype” representing the central tendency of experienced exemplars. Participants were familiarized with a monotonic eight-note melody in two closely separated keys and tested for discrimination of that melody from others. Test and foil melodies included ones that were the “average” of pitch heights and ones that were more distant in pitch height. Hit rates and discriminability (d') were better for physically closer keys than for harmonically related keys. In follow-up experiments, …

Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang Jan 2015

Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang

Wayne State University Theses

The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster Jan 2015

Emotional Enhancement And Repetition Effects During Working Memory In Persons With Mild Cognitive Impairment, Lucas S. Broster

Theses and Dissertations--Clinical and Translational Science

This dissertation introduces a framework for understanding differences in how emotional enhancement effects might influence memory in aging adults and then summarizes the findings of three studies of how repetition effects and emotional enhancement effects influence working memory in older adults without cognitive impairment (NC), older adults with amnestic mild cognitive impairment (MCI), and older adults with mild Alzheimer’s disease (AD). In these experiments, individuals with AD showed cognitive impairment in terms of accuracy and reaction time, but individuals with MCI showed milder behavioral impairment that was confined to manipulations of working memory. Individuals with AD showed relative sparing of …

Mind-Craft: Exploring The Relation Between "Digital" Visual Experience And Orientation In Visual Contour Perception, Daniel Hipp Jan 2015

Mind-Craft: Exploring The Relation Between "Digital" Visual Experience And Orientation In Visual Contour Perception, Daniel Hipp

Graduate Dissertations and Theses

Visual perception depends fundamentally on statistical regularities in the environment to make sense of the world. One such regularity is the orientation anisotropy typical of natural scenes; most natural scenes contain slightly more horizontal and vertical information than oblique information. This property is likely a primary cause of the “oblique effect” in visual perception, in which subjects experience greater perceptual fluently with horizontally and vertically oriented content than oblique. However, recent changes in the visual environment, including the “carpentered” content in urban scenes and the framed, caricatured content in digital screen media presentations, may have altered the level of orientation …

A Narrative Study Of Emotions Associated With Negative Childhood Experiences Reported In The Adult Attachment Interview, Lynne Hartman Jan 2015

A Narrative Study Of Emotions Associated With Negative Childhood Experiences Reported In The Adult Attachment Interview, Lynne Hartman

Antioch University Dissertations & Theses

Attachment patterns, which tend to be stable over time, are passed from one generation to the next. Secure attachment has been linked to adaptive social functioning and has been identified as a protective factor against mental illness. The parents’ state of mind with regard to attachment—as measured with the Adult Attachment Interview (AAI) (Main, Goldwyn, & Hesse, 2002)—predicts the attachment classification for the infant in Ainsworth’s Strange Situation Procedure (Ainsworth, Blehar, Waters, & Wall, 1978). Earned-secure individuals have overcome negative childhood experiences to achieve a secure state of mind in adulthood. Earned security, like continuous security, strongly predicts infant security …

The Effects Of Social Anxiety And State Anxiety On Visual Attention: Testing The Vigilance–Avoidance Hypothesis, J. Suzanne Singh, Michelle C. Capozzoli, Michael Dodd, Debra Hope Jan 2015

The Effects Of Social Anxiety And State Anxiety On Visual Attention: Testing The Vigilance–Avoidance Hypothesis, J. Suzanne Singh, Michelle C. Capozzoli, Michael Dodd, Debra Hope

Department of Psychology: Faculty Publications

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study adds to this literature by examining the effects of state anxiety on visual attention and testing the vigilance– avoidance hypothesis, using a method of continuous visual attentional assessment. Participants were 91 undergraduate college students with high or low trait fear of negative evaluation (FNE), a core aspect of social anxiety, who were randomly assigned to either a high or low state anxiety condition. Participants engaged in a free view task in which pairs of …

A Naturalistic Computational Model Of Human Behavior In Navigation And Search Tasks, Brandon S. Perelman Jan 2015

A Naturalistic Computational Model Of Human Behavior In Navigation And Search Tasks, Brandon S. Perelman

Dissertations, Master's Theses and Master's Reports - Open

Planning, navigation, and search are fundamental human cognitive abilities central to spatial problem solving in search and rescue, law enforcement, and military operations. Despite a wealth of literature concerning naturalistic spatial problem solving in animals, literature on naturalistic spatial problem solving in humans is comparatively lacking and generally conducted by separate camps among which there is little crosstalk. Addressing this deficiency will allow us to predict spatial decision making in operational environments, and understand the factors leading to those decisions. The present dissertation is comprised of two related efforts, (1) a set of empirical research studies intended to identify characteristics …

The Relationship Between English Language Learners And Reading Disabilities Profiles: Language Acquisition Vs. Reading Disabilities, Emily S. Hartz Jan 2015

The Relationship Between English Language Learners And Reading Disabilities Profiles: Language Acquisition Vs. Reading Disabilities, Emily S. Hartz

PCOM Psychology Dissertations

School psychologists are asked to determine whether or not a student’s limited English proficiency affects his or her eligibly for special education services. Scores from language proficiency tests, such as the WIDA ACCESS for ELLs English Language Proficiency Test, are often the only data available that speak to a student’s language proficiency. There is little research that speaks to how scores on these tests relate to performance on diagnostic testing for special education, specifically achievement testing. In this sample of data drawn from a population of English language learners, who also qualify for special education services under the disability of …

Developing Executive Functions Through Mindfulness Training In School-Aged Children, Ashley Black Adams Jan 2015

Developing Executive Functions Through Mindfulness Training In School-Aged Children, Ashley Black Adams

PCOM Psychology Dissertations

Well-developed executive functions are necessary for successful classroom functioning. Students with executive function deficits can fall behind academically as well as socially and emotionally, relative to their same-aged peers. Effective interventions for developing executive functions within the school environment are essential for addressing this issue. This study examines changes in students’ executive functions as a result of their participation in a mindfulness training intervention. Participants included four ten-year old elementary school boys who took part in a ten-week mindfulness training intervention. The data were generated through pre and post assessments with an executive function teacher rating scale and a Goal-Attainment …

The Development And Tryout Of A Program Designed To Increase Students' Multiplication Fact Fluency, Linton D. Williams Jan 2015

The Development And Tryout Of A Program Designed To Increase Students' Multiplication Fact Fluency, Linton D. Williams

PCOM Psychology Dissertations

Fluency skills are fundamental to the ability to complete relatively more complex problems using less mental energy. Most math curriculums do not stress the importance of automaticity of math facts. Variations in teaching styles and teaching modality seem to negate the true purpose for cementing and rapidly retrieving math facts. This study put to the test a program that was designed to increase students’ ability to retrieve multiplication facts fluently. The program exercised cognitive structures and enabled students to retrieve multiplication facts quickly. The results of a matched-pairs t-test indicated that after the students completed the course of the program, …

The Educational Potential Of Alcohol-Related Flushing Among Chinese Young People, Ian M. Newman, Duane F. Shell, Zhaoqing Huang, Ling Qian Jan 2015

The Educational Potential Of Alcohol-Related Flushing Among Chinese Young People, Ian M. Newman, Duane F. Shell, Zhaoqing Huang, Ling Qian

Department of Educational Psychology: Faculty Publications

Aim: This paper describes Chinese university students’ understanding of the meaning of the alcohol-related flushing response and how they reacted to their own and someone else’s flushing in a group drinking situation. Method: The researcher surveyed 530 Chinese university students about their understanding of flushing and their perception of how people respond to a person who visibly flushes while drinking alcohol. Findings: Most students did not know about the physiological cause of flushing. There were significant gender differences in both reactions to and perception of responses to a person who flushes. There was no direct relationship between flushing and drinking …

Teachers Matter: An Examination Of Student-Teacher Relationships, Attitudes Toward Bullying, And Bullying Behavior, Cixin Wang, Susan M. Swearer, Paige T. Lembeck, Adam Collins, Brandi Berry

Department of Educational Psychology: Faculty Publications

This study investigated the influence of student-teacher relationships and attitudes toward bullying on middle school students’ bullying behaviors. Gender and grade differences were also examined. Data were collected from 435 middle school students. Results indicated that students’ attitudes toward bullying mediated the relationship between student-teacher relationships and physical and verbal/relational bullying. There was a significant group difference on student-teacher relationships and attitudes toward bullying between bully, bully-victim, victim, and bystander groups and students not involved in bullying. In addition, sixth graders reported significantly more positive student-teacher relationships than seventh and eighth graders. Implications for the role of both cognitive and …

Descriptions Of Sampling Practices Within Five Approaches To Qualitative Research In Education And The Health Sciences, Tim Guetterman Jan 2015

Descriptions Of Sampling Practices Within Five Approaches To Qualitative Research In Education And The Health Sciences, Tim Guetterman

Department of Educational Psychology: Faculty Publications

Although recommendations exist for determining qualitative sample sizes, the literature appears to contain few instances of research on the topic. Practical guidance is needed for determining sample sizes to conduct rigorous qualitative research, to develop proposals, and to budget resources. The purpose of this article is to describe qualitative sample size and sampling practices within published studies in education and the health sciences by research design: case study, ethnography, grounded theory methodology, narrative inquiry, and phenomenology. I analyzed the 51 most highly cited studies using predetermined content categories and noteworthy sampling characteristics that emerged. In brief, the findings revealed a …

The Window To The Bilingual Mind: Eye Movements Reveal Psycholinguistic Grain Unit Sizes Of Bilingual Spoken Word Recognition, Yu-Cheng Lin Jan 2015

The Window To The Bilingual Mind: Eye Movements Reveal Psycholinguistic Grain Unit Sizes Of Bilingual Spoken Word Recognition, Yu-Cheng Lin

Open Access Theses & Dissertations

Although there are common phonological units across different languages, previous studies have shown that individual differences of language proficiency affect sound unit preferences in monolingual and bilingual speakers. The cross-language lexical activation of phonological representations in bilingual minds can provide a great opportunity for testing hypotheses about how this key factor modulates the cross-linguistic phonological transfer across languages. In this study, I used the eye-tracking technique and quantitative methods (i.e., growth curve analysis and multilevel regression) to examine how individual differences in language proficiency affect cross-language phonological unit size transfer in Chinese-English bilinguals. Participants heard a spoken word and were …

The Ripple Effects Of Stranger Harassment On Objectification Of Self And Others, Meghan Davidson, Sarah Gervais, Lindsey W. Sherd Jan 2015

The Ripple Effects Of Stranger Harassment On Objectification Of Self And Others, Meghan Davidson, Sarah Gervais, Lindsey W. Sherd

Department of Educational Psychology: Faculty Publications

Despite the frequency and negative consequences of stranger harassment, only a scant number of studies have explicitly examined stranger harassment and its consequences through the lens of objectification theory. The current study introduced and tested a mediation model in which women’s experiences of stranger harassment may lead to self-objectification, which in turn may lead to objectification of other people. To examine this model, undergraduate women (N = 501) completed measures of stranger harassment (including the verbal harassment and sexual pressure subscales of the Stranger Harassment Index), body surveillance, and objectification of other women and men. Consistent with hypotheses, significant positive …
