Exploring The Effects Of Brief Mindfulness And Reappraisal Training On Executive Control And Affect, Lee Schaefer

Psychology Theses

Despite the efficacy of mindfulness-based interventions for a wide range of psychological problems, their mechanisms remain unknown. Analogue studies of key treatment components can help distinguish these approaches. One such component, focused-breathing meditation, has rarely been studied in direct comparison to another active and theoretically distinct technique, cognitive reappraisal. The present study examined the effects of mindful breathing and cognitive reappraisal instructions on negative affect and executive control, two potential mechanisms of mindfulness, in a laboratory setting. Non-clinical college undergraduates (N = 136) were randomly assigned to a 10-minute mindfulness, reappraisal, or mind-wandering control condition. Contrary to hypotheses, no …

The Role Of Diverse Strategies In The Sustainability Of Online Communities, Lingfei Wu, Jacopo A. Baggio, Marco A. Janssen

Environment and Society Faculty Publications

Online communities are becoming increasingly important as platforms for large-scale human cooperation. These communities allow users seeking and sharing professional skills to solve problems collaboratively. To investigate how users cooperate to complete a large number of knowledge-producing tasks, we analyze Stack Exchange, one of the largest question and answer systems in the world. We construct attention networks to model the growth of 110 communities in the Stack Exchange system and quantify individual answering strategies using the linking dynamics on attention networks. We identify two answering strategies. Strategy A aims at performing maintenance by doing simple tasks, whereas strategy B aims …

Our Students’ Minds Matter: Integrating Mindfulness Practices Into Special Education Classrooms, Danielle Magaldi Ph.D., Jennie Park-Taylor Ph.D.

The Journal of Special Education Apprenticeship

Mindfulness is defined as the ability to regulate and control one’s attention with an orientation toward the present moment. Mindfulness practices of breathing, imagery, movement, reflection, and acceptance exercises are described along with research on the social, behavioral, and attentional effects following mindfulness interventions. The article concludes with practical considerations for special educators considering implementing mindfulness practices into curriculum, along with future directions for mindfulness in the field of special education.

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 …

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 …

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 …

A Network Analysis Of Developmental Change In Adhd Symptom Structure From Preschool To Adulthood, Michelle M. Martel, Cheri A. Levinson, Julia K. Langer, Joel T. Nigg

Psychology Faculty Publications

Although there is substantial support for the validity of the diagnosis of attention-deficit/hyperactivity disorder (ADHD), there is considerable disagreement about how to best capture developmental changes in the expression of ADHD symptomatology. This article examines the associations among the 18 individual ADHD symptoms using a novel network analysis approach, from preschool to adulthood. The 1,420 participants were grouped into four age brackets: preschool (ages 3–6, n = 109), childhood (ages 6–12, n = 548), adolescence (ages 13–17, n = 357), and young adulthood (ages 18–36, n = 406). All participants completed a multistage, multi-informant diagnostic process, and self and informant …

Now Hear This: Inattentional Deafness Depends On Task Relatedness, Donald J. Tellinghuisen, Alexander J. Cohen, Natalie J. Cooper

University Faculty Publications and Creative Works

Mixed results have been found for the impact of auditory information presented during high-perceptual-load visual search tasks, with some studies showing large effects and others indicating inattentional deafness, with such stimuli going largely undetected. In three experiments, we demonstrated that task relatedness is a key factor in whether extraneous auditory stimuli impact high-load visual searches. Experiment 1 addressed a methodological concern (e.g., Lavie Trends in Cognitive Sciences, 9, 75–82, 2005) regarding the timing of the relative onsets and offsets of task-related, to-be-ignored auditory stimuli and visual search arrays in experiments that have shown auditory distractor effects. Robust auditory distractor effects …

Using A Bci To Assess Attention During An Online Lecture, Ethan Hanner, Marguerite Doman

The Winthrop McNair Research Bulletin

Brain computer interfaces (BCI) use neural signals as input into computer applications. In this study, we demonstrate the use of a low-cost, commercially available BCI to directly measure participants’ attention levels while using WUtopia, and online learning platform developed at Winthrop University. Previous research demonstrated that students using this platform performed better on a post-lecture quiz than those who only viewed the lecture (Grossoehme et al.). We hypothesize that the increase in performance is due to an increase in attentiveness when using the WUtopia platform. We divided participants into the intervention (n = 7) and non-intervention (n = 12) groups. …

Mindfulness Modulated Attention With Neurofeedback In Multiple Object Tracking, Jennifer M. Brennan

Master's Theses

Attention determines what we selectively perceive out of all available stimuli. The multiple-object tracking paradigm is a way of examining divided attention for object tracking in a complex visual scene. Mindfulness is a broad term for a set of diverse and specific methods for distinct attentional engagement and is one technique for increasing visual attentional ability and decreasing distractibility. Neurofeedback can be a way of enhancing mindfulness training for novice participants. This study examined the relationship between attention and mindfulness with neurofeedback through performance on a multiple-object tracking task and the Five Facet Mindfulness Questionnaire. We examined the effectiveness of …

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 …

Naturalizing Anthropomorphism: Behavioral Prompts To Our Humanizing Of Animals, Alexandra C. Horowitz, Marc Bekoff

Marc Bekoff, PhD

Anthropomorphism is the use of human characteristics to describe or explain nonhuman animals. In the present paper, we propose a model for a unified study of such anthropomorphizing. We bring together previously disparate accounts of why and how we anthropomorphize and suggest a means to analyze anthropomorphizing behavior itself. We introduce an analysis of bouts of dyadic play between humans and a heavily anthropomorphized animal, the domestic dog. Four distinct patterns of social interaction recur in successful dog–human play: directed responses by one player to the other, indications of intent, mutual behaviors, and contingent activity. These findings serve as a …

Learning To Be Inflexible: Enhanced Attentional Biases In Parkinson's Disease, Sean James Fallon, Adam Hampshire, Roger A. Barker, Adrian M. Owen

Brain and Mind Institute Researchers' Publications

Impaired attentional flexibility is considered to be one of the core cognitive deficits in Parkinson's disease (PD). However, the mechanisms that underlie this impairment are contested. Progress in resolving this dispute has also been hindered by the fact that cognitive deficits in PD are heterogeneous; therefore, it is unclear whether attentional impairments are only present in a subgroup of patients. Here, we demonstrate that what differentiates PD patients from age-matched controls is an inability to shift attention away from previously relevant information (perseveration) and an inability to shift attention towards previously irrelevant information (learned irrelevance). In contrast, there was no …

Adult Adhd: Effects On Student Performance Within The Online Classroom, Freda Jeanetta Barnett-Braddock

Doctoral Dissertations and Projects

The purpose of this causal-comparative study was to determine the impact, if any, that adult ADHD has on student performance within the online classroom. The researcher sought to identify any underlying correlations which exist that will impact benchmark assessment grades (final exam essay), grade point average (GPA), and course completion rates for students who are highly likely to have ADHD when compared with their neurotypical counterparts. The 41 participants were adult learners who were enrolled in an online, general education course at a university located in the southeastern portion of the United States. Independent samples t-tests and Chi Square tests …

Perceiving Oldness In Parietal Cortex: Fmri Characterization Of A Parietal Memory Network, Adrian Gilmore

Arts & Sciences Electronic Theses and Dissertations

The manner in which the human brain recognizes certain stimuli as novel or familiar is a matter of ongoing investigation. The overarching goal of this dissertation is to improve our understanding of how this may be accomplished. More specifically, work contained herein focuses on a recently described "parietal memory network" (PMN; Gilmore et al., 2015) that shows opposite patterns of activity when perceiving novel or familiar stimuli: deactivating in response to novelty, and activating in response to familiarity. Critically, our understanding of this network is based on explicit memory tasks, in which subjects are deliberately instructed to learn or remember …

Task Residual Functional Connectivity In Language And Attention Networks, Stella Tran

Psychology Theses

The present study compared network specificity between task-residual and resting state data types. Task-residual data capitalizes on the remaining variance after the mean task-related signal is removed from the time series. This study also examined how inter- and intrahemispheric connectivity (bilateral homologous regions and regions contained within the same hemisphere, respectively) within the language and attention networks change as a result of age. Task-residual functional connectivity evidenced stronger laterality of the language and attention connections and thus greater network specificity than resting state functional connectivity of the same connections. Using task-residual data may be optimal for characterizing the synchronized fluctuations …

An Examination Of Associations Among Components Of Mindfulness And Women's Attention Bias To Sad Faces, Cheryl Garn

Psychology Dissertations

Mindfulness, a set of techniques for engaging with stimuli in the present-moment environment, has recently received considerable attention in the literature. Mindfulness is drawn from Eastern, Buddhist traditions and has been integrated into contemporary psychology, in part, as a technique for improving the ability to respond skillfully to emotionally distressing stimuli and processes (Bishop, et al., 2004). However, the boundaries of the mindfulness construct have yet to be solidly established; a variety of definitions exist and are used inconsistently in the literature. Clarifying how engaging attentional control processes in response to emotionally-charged stimuli, such as sad faces, relates to precisely-articulated …

Visual Attention And Its Relation To Knowledge States In Chimpanzees, Pan Troglodytes, Megan J. Bulloch, Sarah T. Boysen, Ellen E. Furlong

Sarah Boysen, PhD

Primates rely on visual attention to gather knowledge about their environment. The ability to recognize such knowledge-acquisition activity in another may demonstrate one aspect of Theory of Mind. Using a series of experiments in which chimpanzees were presented with a choice between an experimenter whose visual attention was available and another whose vision was occluded, we asked whether chimpanzees understood the relationship between visual attention and knowledge states. The animals showed sophisticated understanding of attention from the first presentation of each task. Under more complex experimental conditions, the subjects had more difficulty with species-typical processing of attentional cues and those …

The Effect Of Content-Related And Unrelated Break Activities On Test Results, Ryan Gentek

Theses and Dissertations

Researchers have recently explored using brief breaks to maintain performance during prolonged tasks (Ariga and Lleras, 2011). However, research has yet to fully explore the effect of break activity content on the performance of the primary task. The present study sought to explore the differing effects of two break activities that were respectively similar and different in content to the main task. The present researcher compared past studies of task-switching and interruption studies to theories of the vigilance decrement and hypothesized that a brief similar task should result in significantly different main-task performance than the brief dissimilar task. 20 participating …

Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout

Theses and Dissertations

Dispositional anxiety is an important risk factor for the development of anxiety and other psychological disorders. Symptoms commonly expressed by highly anxious individuals include intrusive memories, uncertainty, and worry — all occurring in the absence of immediate threat. This raises the possibility that anxious individuals have difficulty governing threat’s access to working memory, the mental workspace where goal-related information is actively retained for guiding on-going behavior. Using functional magnetic resonance imaging (fMRI) while 81 subjects completed a well-validated working memory task, I show that threat-related and neutral distracters unnecessarily gain access to working memory, as evidenced by increased neural activity …

The Effects Of Mindfulness Practices And Activities On Student Attention And Work Engagement In A Multi-Age 4th To 6th Grade Montessori Classroom, Jamie L. Schaub

Masters of Arts in Education Action Research Papers

The purpose of this research was to test whether the implementation of mindfulness exercises would increase focus and work engagement of students. This study incorporated breathing and visualization exercises three times a week. The 5-week study involved 44 children between the ages of 9 and 12 years in a private Montessori school in Northern Michigan. Data collection included daily tallies of on and off task behavior, daily observations of work engagement, pre and post questionnaires about mindfulness completed by each child, and oneon- one discussions with each participant. Results showed an increase in the number of students on task and …

Global/Local Processing In Incidental Perception Of Hierarchical Structure, Mark S. Mills

Department of Psychology: Dissertations, Theses, and Student Research

The goal of the current thesis is to provide a framework for investigating and understanding visual processing of hierarchical structure (i.e., local parts nested in global wholes, such as trees nested in forests) under incidental processing conditions—that is, where processing of information at global and local levels is both uninformative (cannot aid task performance) and task-irrelevant (need not be processed to perform the task). To do so, a novel method combining two widely-used paradigms (spatial cueing and compound stimulus paradigms) is used for implicitly probing observers’ perceptual representations over the course of processing. This compound arrow cueing paradigm was used …

Effects Of Classroom-Based Physical Activities On Off-Task Behaviors And Attention: Kindergarten Case Study, Sara Wiebelhaus, Michelle Fryer Hanson

The Qualitative Report

The qualitative case study’s purpose was to determine if classroom-based physical activities would affect student off-task behaviors during instruction and students’ perceptions of ability to focus before and after activities. Research questions focused on kindergarteners’ ability to focus after classroom-based physical activity, perceptions of their ability to focus change with implementation of classroom-based physical activity, and effect of classroom-based physical activity on behavior. Kindergarteners were involved in daily activity stations such as jumping on trampolines, walking balance beams, crawling, and hopscotch. Three students were purposively selected as participants. Data were collected using interviews, video recordings, field notes, and off-task behavior …

The Effects Of Concurrent Cognitive Load On The Processing Of Clear And Degraded Speech, Harrison Ritz

Electronic Thesis and Dissertation Repository

A previous study has found that perceiving degraded speech requires attention, with compromised behavioral and neurological measures of speech processing for degraded speech, but not clear speech, when participants are distracted (Wild et al., 2012b). We extended these findings by examining behavioral and neural correlates of speech perception under different levels of cognitive load using multiple object tracking. We also investigated the role of attention in perceiving degraded speech that was as intelligible as clear speech, in order to separate perceptual outcomes (i.e., intelligibility) from the requisite processing demands. We found that the speech perception system is heterogeneous in its …

Teacher Mindfulness In The Middle School Classroom: Reliability And Validity Of A New Scale, Nicolette Paige Rickert

Dissertations and Theses

Despite significant growth in research examining the effects of mindfulness interventions on teachers (Roeser, 2014), studies have mainly relied on self-reports of teacher mindfulness and have not examined observable behavioral manifestations of teacher mindfulness in the classroom. Due to possible biases in self-report measures (Dotterer & Lowe, 2011), as well as the need for a greater range of assessments of the effects of mindfulness trainings on teachers, the current study sought to create a new measure of teacher mindfulness in the classroom from three sources of information: teacher self-reports of their own behavior in the classroom, student perceptions of their …

Self-Reported Responses To Player Profile Questions Show Consistency With The Use Of Complex Attentional Strategies By Expert Horseshoe Pitchers, Jeffrey T. Fairbrother, Phillip G. Post, Samuel J. Whalen

Kinesiology, Recreation, and Sport Studies Publications and Other Works

The advantages on an external focus of attention have been demonstrated for a variety of sport tasks. The constrained action hypothesis (Wulf et al., 2001) argues that focusing externally on the movement effect results in the use of automated processes for movement control. In contrast, focusing internally in an attempt to control the movements of the body disrupts normally automated processes and degrades performance. Research on experts, however, suggests that they may adopt more complex attentional strategies. The present study provided a unique opportunity to examine expert horseshoe players’ attentional strategies as indicated by their self-reported responses to …

The Development Of Attention To Dynamic Facial Emotions, Alison Heck, Alyson Hock, Hannah White, Rachel Jubran, Ramesh Bhatt

Psychology Faculty Works

Appropriate processing of emotions is paramount for successful social functioning. Adults’ enhanced attention to negative emotions such as fear is thought to be a critical aspect of this adaptive functioning. Prior studies indicate that increased attention to fear relative to positive or neutral emotions begins at around 7 months of age, and it has been suggested that this negativity bias is related to self-locomotion. However, these studies mostly used static faces, potentially limiting information available to the infants. In the current study, 3.5-month-olds (n = 24) and 5-month-olds (n = 24) were exposed to dynamic faces expressing fear, happy, or …

The Development Of White Asian Categorization: Contributions From Skin Color And Other Physiognomic Cues, Yarrow Dunham, Ron Dotsch, Amelia R. Clark, Elena V. Stepanova

Faculty Publications

We examined the development of racial categorizations of faces spanning the European–East Asian (“White–Asian”) categorical continuum in children between the ages of four and nine as well as adults. We employed a stimulus set that independently varied skin color and other aspects of facial physiognomy, allowing the contribution of each to be assessed independently and in interaction with each other. Results demonstrated substantial development across this age range in children’s ability to draw on both sorts of cue, with over twice as much variance explained by stimulus variation in adults than children. Nonetheless, children were clearly sensitive to both skin …

The Effect Of Yoga On Attention In Students Diagnosed With Adhd, Andrew Petsche

Doctoral Dissertations

ADHD impacts approximately 5% of children and has substantial negative effects on school behaviors, particularly with regard to attention. A number of school-based interventions exist to address the attention and focusing abilities of individuals diagnosed with ADHD; however, all of the existing interventions feature drawbacks such as expense, inefficient uses of time and resources, or negative side effects. Yoga has been shown to be a viable alternative to the traditional treatment methods for ADHD, particularly with regard to improving the attention and concentration levels of students. The present study utilized the Yoga Fitness for Kids videotape as an intervention for …
