Adhd Symptoms And Inattentional Blindness In An Undergraduate Sample, Katherine Rose Matchett
Adhd Symptoms And Inattentional Blindness In An Undergraduate Sample, Katherine Rose Matchett
Electronic Theses and Dissertations
The relationship between Attention-Deficit/Hyperactivity Disorder (ADHD) and the phenomenon of inattentional blindness has received little empirical attention, with only a single published study on the topic. The purpose of the present study was to investigate individual differences in ADHD symptom severity in a non-clinical, undergraduate sample as they relate to susceptibility to inattentional blindness. Because research conducted in an individual differences framework requires the use of reliable measurement instruments, the present study also set out to develop and pilot a task that could induce inattentional blindness repeatedly and reliably in the same participants. The results showed that a) the measure …
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Electronic Theses and Dissertations
Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …
An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios
An Examination Of Working Memory, Spatial Awareness And Expertise In Athletes, Non-Athletes And Sports-Fans, Camilia Rios
Electronic Theses and Dissertations
Sport-specific practice of movement techniques is undoubtedly important in young athletes' sport performance. However, in sports that are more heavily reliant on open skills, cognitive factors, such as working memory (WM), attention, and spatial awareness, are more likely to become a barrier for proficiency than form or physical prowess. Nevertheless, the intricacies of the relationships that exist between these cognitive factors has gone relatively unexplored, particularly in the context of sport. The present research explored the impact of sport-specific experience on measures of WM, attentional control, and spatial awareness, and their interactions, through the lens of athletic expertise. Participants consisted …
The Effect Of School-Based Mindfulness Intervention On Student Attention And Executive Function: A Meta-Analysis, Sarah E. Rea
The Effect Of School-Based Mindfulness Intervention On Student Attention And Executive Function: A Meta-Analysis, Sarah E. Rea
Electronic Theses and Dissertations
Schools are facing increasing responsibility to foster the social-emotional development of students. One way in which schools can improve student functioning is through school-based mindfulness interventions. Using mindfulness practices, in particular, can teach students to increase their attention of surroundings and internal experiences, and awareness of their thoughts and behaviors. While the evidence-base for mindfulness interventions in schools continues to grow, there are several studies that show promising outcomes. The purpose of this study was to determine how large the effect sizes for school-based mindfulness studies are in regard to increasing student attention, cognitive flexibility, and working memory. Results indicate …
Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.
Functional Opponency In Working Memory Capacity Predicts Cognitive Flexibility In Problem Solving., Charles A. Van Stockum Jr.
Electronic Theses and Dissertations
Cognitive flexibility is a hallmark of individuals with higher working memory capacity (WMC). Yet, research demonstrates that higher WMC individuals are sometimes more likely to adopt rigid problem-solving approaches. The present research examines a novel account for these contradictory findings—that different WMC mechanisms interact in ways that both support and constrain cognitive flexibility. Across three studies, participants completed the water jug task—a problem-solving task requiring them to first establish and then break mental set using a complex strategy. Participants then completed measures targeting three WMC mechanisms: attention control, primary memory, and secondary memory. Study 1 demonstrated that primary memory and …
Biopsychosocial Models Of The Development Of Childhood Disruptive Behaviors, Anne Bernard Arnett
Biopsychosocial Models Of The Development Of Childhood Disruptive Behaviors, Anne Bernard Arnett
Electronic Theses and Dissertations
Hyperactivity/attention problems (HAP) and conduct problems (CP) are common and impairing disruptive behaviors in childhood and adolescence. Previous research has established that HAP and CP are highly comorbid, and that outcomes are worse for youth exhibiting both symptom clusters relative to youth with only one disruptive behavior type. Despite ample evidence that HAP and CP share common etiological factors and maladaptive outcomes, the nature of their developmental association remains unclear. This dissertation clarifies three important characteristics of comorbid HAP and CP development, in two replicate, longitudinal, population samples of youth. First, I test the theory that within-person variation in HAP …
Attention And Mimicry In Minimal Groups, Heidi Blocker
Attention And Mimicry In Minimal Groups, Heidi Blocker
Electronic Theses and Dissertations
There is a group effect on matching behavior; ingroups tend to be matched more than outgroups. Differences in attention to ingroup and outgroup members may correspond with group differences in matching. Determining how both attention and matching are influenced by minimal groups can help distinguish between potential mechanisms used to explain group effects in social behavior. Furthermore, it would be beneficial to know if attention biases can be trained to social groups. Study 1 replicated attention training to neutral faces, but study 2 failed to replicate attention training to emotional faces. Study 3 used the same attention training method, but …
Exploring The Relationship Between Early Childhood Attentional Control And Language Ability, Jaima S. Price
Exploring The Relationship Between Early Childhood Attentional Control And Language Ability, Jaima S. Price
Electronic Theses and Dissertations
Relatively few studies have investigated the relationship between early childhood attentional control and later cognitive outcomes, especially language development. The current study is an investigation of the relationship between the executive functioning (EF) component of attentional control and language ability in the second year of life. More specifically, the predictive nature of two aspects of attentional control, attentional focus and resistance to distraction, was be the primary focus of the proposed study. Although it was expected that children both high in attentional focus and resistance to distraction would have significantly superior language development than infants with lower attentional capacities, analyses …
Cognitive Effects And Academic Consequences Of Video Game Playing, Sean Hollis
Cognitive Effects And Academic Consequences Of Video Game Playing, Sean Hollis
Electronic Theses and Dissertations
Introduction: prior video game playing (vgp) research has generated mixed empirical findings. Recent studies suggested positive effects vgp may have on cognitive skills, particularly improvements in visuospatial skills, processing speed, working memory, multitasking, and problem solving skills. By contrast, other studies have suggested that vgp leads to lower academic performance - indicating further research on vgp effects is needed. This study investigated the effects of vgp on cognitive skills and academic performance. Methods: 208 participants were recruited from the University of Mississippi psychology department in exchange for research participation credit. The sample was 68.9% female and 31.1% male. Ages ranged …
Hyperactivity In Attention-Deficit/Hyperactivity Disorder (Adhd): Testing Functional Relationships With Phonological Working Memory Performance And Attention, Dustin Sarver
Electronic Theses and Dissertations
Excessive gross motor activity is currently considered a ubiquitous and disruptive feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between activity level, attention, and working memory. The current study investigated whether, and the extent to which, particular forms of gross motor activity are functionally related to children’s attention and phonological working memory performance. Objective observations of children’s gross motor movements and attention by independent observers were conducted while children with ADHD (n = 29) and typically developing children (n = 23) completed multiple counterbalanced tasks entailing low and high phonological working …
Do Programs Designed To Train Working Memory, Other Executive Functions, And Attention Benefit Children With Adhd? A Meta-Analytic Review Of Cognitive, Academic, And Behavioral Outcomes, Sarah Orban
Electronic Theses and Dissertations
Children with ADHD are characterized frequently as possessing underdeveloped executive functions and sustained attentional abilities, and recent commercial claims suggest that computer-based cognitive training can remediate these impairments and provide significant and lasting improvement in their attention, impulse control, social functioning, academic performance, and complex reasoning skills. The present review critically evaluates these claims through meta-analysis of 25 studies of facilitative intervention training (i.e., cognitive training) for children with ADHD. Random effects models corrected for publication bias and sampling error revealed that studies training short-term memory alone resulted in moderate magnitude improvements in short-term memory (d= 0.63), whereas training attention …
Attentional Processes Associated With Victimization History And Posttraumatic Symptomatology In Women Exposed To Intimate Partner Violence, Ryan B. Matlow
Attentional Processes Associated With Victimization History And Posttraumatic Symptomatology In Women Exposed To Intimate Partner Violence, Ryan B. Matlow
Electronic Theses and Dissertations
Exposure to intimate partner violence (IPV) puts women at risk for severe and chronic physical and mental health consequences, including elevations in IPV-related psychopathology and increased risk for future victimization. Previous research has examined attention as one of the key information processing mechanisms associated with elevated psychopathology and risk for victimization; however, the nature of attentional processing in response to IPV-related information in women exposed to IPV is poorly understood. Therefore, the current study aimed to further understanding of associations between attentional processing, IPV exposure, and related distress using measures of eye movement and subjective interpretations of IPV-related information. A …
Manipulating Paradigm And Attention Via A Mindfulness Meditation Training Program Improves P300-Based Bci., Daniel Ryan Berry
Manipulating Paradigm And Attention Via A Mindfulness Meditation Training Program Improves P300-Based Bci., Daniel Ryan Berry
Electronic Theses and Dissertations
To date, only one study has situationally bolstered attentional resources in an effort to improve P300-BCI performance. The current study implements a 4-week Mindfulness Meditation Training Program (MMTP) as a nonmedicinal means to increase concentrative attention and to reduce lapses of attention; MMTP is expected to improve P300-BCI performance by enhancing attentional resources and reducing distractibility. A second aim is to test the efficacy of the checkerboard paradigm (CBP) against the standard row-column paradigm (RCP). Online results show that MMTP had greater accuracies than CTRL and that CBP outperformed the RCP. MMTP participants provided greater amplitude positive target responses, but …
Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver
Adhd Behavior Problems And Near- And Long-Term Scholastic Achievement Differential Mediating Effects Of Verbal And Visuospatial Memory, Dustin E. Sarver
Electronic Theses and Dissertations
The current study examined verbal and visuospatial memory abilities as potential mediators of the relationship among ADHD behavior problems and near- and long-term scholastic achievement. Scholastic achievement was measured initially and at 4-year follow-up in an ethnically diverse sample of children (N = 325). Nested composite (reading, math, language) and domain-specific reading structural equation models revealed that ADHD behavior problems exerted a negative influence on scholastic achievement measures, both initially and at follow-up. Much of this influence, however, was mediated by verbal memory’s contribution to near-term achievement, whereas visuospatial memory contributed more robustly to long-term achievement. For the domain-specific math …
Adhd And Working Memory: The Impact Of Central Executive Deficits And Overwhelming Storage/Rehearsal Capacity On Observed Inattentive Behavior, Michael Kofler
Adhd And Working Memory: The Impact Of Central Executive Deficits And Overwhelming Storage/Rehearsal Capacity On Observed Inattentive Behavior, Michael Kofler
Electronic Theses and Dissertations
Inattentive behavior is considered a core and pervasive feature of ADHD; however, an alternative model challenges this premise and hypothesizes a functional relationship between working memory and inattentive behavior. The current study investigated whether inattentive behavior in children with ADHD is functionally related to domain-general central executive and/or subsidiary storage/rehearsal components of working memory. Objective observations of children's attentive behavior by independent observers were conducted while children with ADHD (n=15) and typically developing children (n=14) completed 10 counterbalanced tasks that differentially manipulated central executive, phonological storage/rehearsal, and visuospatial storage/rehearsal demands. Results of latent variable and effect size confidence interval analyses …
A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill
A Comparison Of Attentional Reserve Capacity Across Three Sensory Modalities, John Brill
Electronic Theses and Dissertations
There are two theoretical approaches to the nature of attentional resources. One proposes a single, flexible pool of cognitive resources; the other poses there are multiple resources. This study was designed to systematically examine whether there is evidence for multiple resource theory using a counting task consisting of visual, auditory, and tactile signals using two experiments. The goal of the first experiment was the validation of a multi-modal secondary loading task. Thirty-two participants performed nine variations of a multi-modal counting task incorporating three modalities and three demand levels. Performance and subjective ratings of workload were measured for each of the …
The Relative Sensitivity Of An Olfactory Identification Deficit In Individuals With Schizotypal Personality Features, Vidyulata Kamath
The Relative Sensitivity Of An Olfactory Identification Deficit In Individuals With Schizotypal Personality Features, Vidyulata Kamath
Electronic Theses and Dissertations
Olfactory identification deficits have received recent attention as a potentially useful endophenotype for schizophrenia. Examination of this deficit in individuals with schizotypal personality features (SPF) offers an alternative approach to multiple confounds present when examining individuals with schizophrenia. The aim of the current study was to compare the relative sensitivity of performance on measures of olfaction identification and sustained attention to the presence of SPF. Twenty-six undergraduates were defined as having SPF based on scoring in the top 10% of the Abbreviated Schizotypal Personality Questionnaire (SPQ-B; mean age 19.6, SD = 1.1; 62% female). These individuals were compared to twenty-six …
Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler
Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler
Electronic Theses and Dissertations
Meta-analysis of 23 between-group direct observation studies of children with ADHD and typically developing peers indicates significant deficiencies in children with ADHD's ability to pay attention in classroom settings. Comparison with 59 single case design studies of children with ADHD suggests generalizability of between-group comparisons. Weighted regression analysis determined that several methodological differences sample characteristics, diagnostic procedures, and observational coding schema have significant effects on observed levels of attentive behavior in the classroom. Best case estimation indicates that after accounting for these factors, children with ADHD are on-task approximately 65% of the time compared to 85% for their …
Individual Preferences In The Use Of Automation, Jennifer Thropp
Individual Preferences In The Use Of Automation, Jennifer Thropp
Electronic Theses and Dissertations
As system automation increases and evolves, the intervention of the supervising operator becomes ever less frequent but ever more crucial. The adaptive automation approach is one in which control of tasks dynamically shifts between humans and machines, being an alternative to traditional static allocation in which task control is assigned during system design and subsequently remains unchanged during operations. It is proposed that adaptive allocation should adjust to the individual operators' characteristics in order to improve performance, avoid errors, and enhance safety. The roles of three individual difference variables relevant to adaptive automation are described: attentional control, desirability of control, …
Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome
Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome
Electronic Theses and Dissertations
Advances in simulation technology have brought about many improvements to the way we train tasks, as well as how we perform tasks in the operational field. Augmented reality (AR) is an example of how to enhance the user's experience in the real world with computer generated information and graphics. Visual search tasks are known to be capacity demanding and therefore may be improved by training in an AR environment. During the experimental task, participants searched for enemies (while cued from visual, auditory, tactile, combinations of two, or all three modality cues) and tried to shoot them while avoiding shooting the …
