Effects Of Dissonance And Disruption On Risky Decisions, Wyn E. Taylor

Psychology Theses

All choices develop first from the basic sensory stimuli to which our systems attend, consciously and unconsciously. The cognitive processes which form the basis of decision- making and contextual shifting require attention to both novel and familiar environmental features; from the overwhelming stimulus that assault our senses, we must figure out which environmental features are safe to ignore and those to which we must attend. Separate fast, emotional and slower rational decision processes described by a number of dual-processing theories have found compelling support in neuroscience research examining selective attention gating mechanisms. Indeed, these two systems appear to exert substantial …

Contemplating Mindfulness At Work: An Integrative Review, Christopher Lyddy, Darren J. Good, Theresa M. Glomb, Joyce E. Bono, Kirk W. Brown, Michelle K. Duffy, Ruth A. Baer, Judson A. Brewer, Sara W. Lazar

School of Business Faculty Publications

Mindfulness research activity is surging within organizational science. Emerging evidence across multiple fields suggests that mindfulness is fundamentally connected to many aspects of workplace functioning, but this knowledge base has not been systematically integrated to date. This review coalesces the burgeoning body of mindfulness scholarship into a framework to guide mainstream management research investigating a broad range of constructs. The framework identifies how mindfulness influences attention, with downstream effects on functional domains of cognition, emotion, behavior, and physiology. Ultimately, these domains impact key workplace outcomes, including performance, relationships, and well-being. Consideration of the evidence on mindfulness at work stimulates important …

The Effects Of Rumination Induction On Attentional Breadth For Self-Related Information, Maud Grol, Paula T. Hertel, Ernst H.W Koster, Rudi De Raedt

Paula T Hertel

The attentional scope model of rumination describes the links between rumination and attentional breadth. The model postulates that a more narrow attentional scope, caused by negative mood, increases the likelihood that thoughts become repetitive on the same topic, which in turn could exacerbate negative mood and lead to more attentional narrowing. We experimentally tested this model by examining the attentional effects of rumination using a newly developed rumination- versus problem-solving induction. In the first experiment we found that only at high levels of trait rumination, induction of rumination compared to a problem-solving approach was associated with more attentional narrowing for …

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 …

Facilitating Visual Selective Attention Via Monetary Reward: The Influence Of Feedback, Hedonic Capacity, And Lifetime Major Depressive Disorder, Lauren Elizabeth Taubitz

Theses and Dissertations

Recently, several researchers have demonstrated that reward enhances visual selective attention; however, no one has evaluated how individual differences in reward sensitivity or psychopathology involving disturbances in hedonic capacity (e.g., Major Depressive Disorder (MDD)) affect this process. In this investigation, a novel incentivized visual search task was developed to unite the literatures on reward facilitation of attention with the studies of individual differences in hedonic capacity and remitted MDD (rMDD). 161 undergraduates responded to self-report measures and completed standard and incentivized visual search tasks. In the standard task, subjects had to indicate if a letter F (target) was present or …

Objectively Measuring The Effects Of Sleep On Reading Comprehension And Sustained Selective Attention, Jennifer L. Thibodeaux

Doctoral Dissertations

The overall performance of a university is measured by retention rates of students. Because individuals who achieve lower grade point averages are at a higher risk of failing or dropping out of college, the academic performance of undergraduates should be the target of concern to maintain good retention rates. Academic performance, which is associated with attention and reading comprehension abilities, is affected by the sleep behavior of students. In regards to college students and sleep, research has indicated that college students demonstrate habitually poor sleep habits. Poor sleep habits have been linked to impaired attention and concentration abilities, but the …

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 …

An Evaluation Of Demand Functions For Attention And Food In Children With Autism, Bistra K. Bogoev

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dominant approach to treating social dysfunction in individuals with autism views that dysfunction as a skill deficit. However, another plausible interpretation is that social dysfunction in some individuals arises from motivational deficits. The proposed study presents a method to assess motivational deficits for social attention in individuals with autism. By borrowing methods from behavioral economics, we assessed the essential value for social attention and compared it to the essential value for food.

Five individuals diagnosed with autism were included in the project. First, we assessed preference for food by using paired-preference assessment. To identify preference hierarchy for attention, we …

Attentional Competition: Weapon Focus, Encoding Time, And Memory Accuracy Correlations Between Crime Scene Items, Seyram Kekessie

FIU Electronic Theses and Dissertations

The present study examines the relationships between recognition and recall accuracy of faces, and recognition and recall accuracy of objects. Secondly, this study examines the influence of weapon presence on description and identification accuracy, and whether encoding time moderates the effect. 713 participants watched an image that was either displayed for five seconds or twenty seconds, and either included a weapon or no weapon. Subsequently, they were asked to give descriptions of what they saw before viewing a lineup that either included the perpetrator or was made up of innocent suspects. Results indicated that witnesses’ description accuracy of the crime …

The Effects Of Rumination Induction On Attentional Breadth For Self-Related Information, M. Grol, Paula T. Hertel, E. H.W. Koster, Rudi De Raedt

Belief About Nicotine Selectively Modulates Value And Reward Prediction Error Signals In Smokers, Xiaosi Gu, Terry Lohrenz, Ramiro Salas, Philip R. Baldwin, Alireza Soltani

Dartmouth Scholarship

Little is known about how prior beliefs impact biophysically described processes in the presence of neuroactive drugs, which presents a profound challenge to the understanding of the mechanisms and treatments of addiction. We engineered smokers' prior beliefs about the presence of nicotine in a cigarette smoked before a functional magnetic resonance imaging session where subjects carried out a sequential choice task. Using a model-based approach, we show that smokers' beliefs about nicotine specifically modulated learning signals (value and reward prediction error) defined by a computational model of mesolimbic dopamine systems. Belief of "no nicotine in cigarette" (compared with "nicotine in …

Attention In Hiv, Kathleen Marie Van Dyk

Dissertations, Theses, and Capstone Projects

In contrast to the striking benefit of advances in antiretroviral therapy on longevity and health in the HIV+ population, mild cognitive disorders persist (Heaton, Clifford et al., 2010). Additional factors that may be related to cognitive decline and warrant consideration in this population are aging and physical health status. Among cognitive domains affected, attention and processing speed have emerged as particularly vulnerable to the effects of HIV. There are also age effects observed in these domains, and we proposed that reduced physical health can also impact cognition in these areas, comparably to pain. Sensitive measures of attention that vary attentional …

The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy

Dissertations, Theses, and Capstone Projects

Our ability to selectively attend to certain aspects of the world and ignore others is fundamental to our day-to-day lives. The need for selective attention stems from capacity limitations inherent in our perceptual and cognitive processing architecture. Because not every elemental piece of our environment can be fully processed in parallel, the nervous system must prioritize processing. This prioritization is generally referred to as selective attention. Meanwhile, we are faced with a world that is constantly in flux, such that we have to frequently shift our attention from one piece of the environment to another and from one task to …

Attentional Filtering Of Visual Information By Neuronal Ensembles In The Primate Lateral Prefrontal Cortex., Sébastien Tremblay, Florian Pieper, Adam Sachs, Julio Martinez-Trujillo

Brain and Mind Institute Researchers' Publications

The activity of neurons in the primate lateral prefrontal cortex (LPFC) is strongly modulated by visual attention. Such a modulation has mostly been documented by averaging the activity of independently recorded neurons over repeated experimental trials. However, in realistic settings, ensembles of simultaneously active LPFC neurons must generate attentional signals on a single-trial basis, despite the individual and correlated variability of neuronal responses. Whether, under these circumstances, the LPFC can reliably generate attentional signals is unclear. Here, we show that the simultaneous activity of neuronal ensembles in the primate LPFC can be reliably decoded to predict the allocation of attention …

Emergent Literacy Skills In Print And Electronic Contexts: The Influence Of Book Type, Narration Style, And Attention, Kathryn Joyce O'Toole

Dissertations

Preschoolers can learn words and story content from traditional print books, but there has been no direct comparison of their learning from print and e-books while controlling for narration style. Additionally, very little empirical work has utilized a tablet e-book as the majority of research has examined learning from computer e-books. The current project examined how 4-year-olds (N = 100) learned words and story content from four different book reading contexts: a print book read aloud by a live adult, a print book narrated by an audio device, a tablet e-book read aloud by a live adult, or a tablet …

Increased Attention And Memory For Beloved-Related Information During Infatuation: Behavioral And Electrophysiological Data, Sandra J. E. Langeslag, Jamie R. Oliver, Martine E. Köhlen, Ilse M. Nijs

Psychology Faculty Works

Emotionally salient information is well attended and remembered. It has been shown that infatuated individuals have increased attention for their beloved. It is unknown whether this attention bias generalizes to information related to the beloved. Moreover, infatuated individuals report to remember trivial things about their beloved, but this has not yet been tested empirically. In two studies, we tested whether infatuated individuals have increased attention and memory for beloved-related information. In a passive viewing task (Study 1), the late positive potential, an event-related potential (ERP) component reflecting motivated attention, was enhanced for beloved-related vs friend-related words/phrases. In a recognition task …

Activating The Biological And Behavioral Immune Systems, Julia Christensen

Departmental Honors Projects

Psychology recognizes two distinct facets of the immune system: the biological immune system (BIO), covering all processes of the typical immune system, and the behavioral immune system (BEH), a set of cognitive, emotional, and behavioral responses to environmental stimuli. Research on this dual immune system indicates that each is capable of influencing the other (Schaller & Park, 2011). For example, perception of illness in others can activate the sympathetic nervous system (Schaller, Miller, Gervais, Yager, & Chen, 2010). Furthermore, evidence suggests that these two systems are capable of influencing moral judgment (Inbar, Pizarro, & Bloom, 2008). This study aims to …

Cognitive Fatigue: Exploring The Relationship Between The Fatigue Effect And Action Video-Game Experience, James Brooks

Theses: Doctorates and Masters

the effects of cognitive fatigue. Despite this, there remain advantages to regularly playing action video games. In Study 1, VGPs were significantly better at multitasking on the MATB-II compared to the NVGPs. Further, VGPs also demonstrated superior multitasking when driving, as they made significantly fewer traffic violations compared to NVGPs when not fatigued. VGPs demonstrated eye-movements similar to those of expert drivers; however, this did not result in any difference in performance between the two groups. There was also some evidence of a positive effect of video game training, although there was no advantage of one training technique over the …

Obama Cares About Visuo-Spatial Attention: Perception Of Political Figures Moves Attention And Determines Gaze Direction, Mark S. Mills, Kevin B. Smith, John R. Hibbing, Michael D. Dodd

Department of Psychology: Faculty Publications

Processing an abstract concept such as political ideology by itself is difficult but becomes easier when a background situation contextualizes it. Political ideology within American politics, for example, is commonly processed using space metaphorically, i.e., the political “left” and “right” (referring to Democrat and Republican views, respectively), presumably to provide a common metric to which abstract features of ideology can be grounded and understood. Commonplace use of space as metaphor raises the question of whether an inherently non-spatial stimulus (e.g., picture of the political “left” leader, Barack Obama) can trigger a spatially-specific response (e.g., attentional bias toward “left” regions of …

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 …

Impact Of Urban Nature On Executive Functioning In Early And Middle Childhood, Anne R. Schutte, Julia C. Torquati, Heidi L. Beattie

Department of Psychology: Faculty Publications

According to attention restoration theory, directed attention can become fatigued and then be restored by spending time in a restorative environment. This study examined the restorative effects of nature on children’s executive functioning. Sevento 8-year-olds (school aged, n = 34) and 4- to 5-year-olds (preschool, n = 33) participated in two sessions in which they completed an activity to fatigue attention, then walked along urban streets (urban walk) in one session and in a park-like area (nature walk) in another session, and finally completed assessments of working memory, inhibitory control, and attention. Children responded faster on the attention task after …

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 …

Eye Movement Patterns As An Indicator Of Task Automaticity, Olga Clarke

Theses : Honours

Automaticity is a vital aspect of daily living, as it allows for tasks to be completed quickly and with the fraction of the cognitive load required for tasks that cannot be completed automatically. Task automaticity is commonly measured with reaction time, which is considered to be an indirect measure of behaviour. As more direct measures are becoming available, there is an opportunity to assess task automaticity in greater detail. The purpose of the current study was to determine whether eye movements change as participants reach task automaticity. The study involved 16 participants who were asked to complete the dot counting …

When Auditory And Visual Signal Processing Conflict: Cross-Modal Interference In Extended Work Periods, Stephen J. Guastello, Katherine Reiter, Matthew Malon, Anton Shircel

Psychology Faculty Research and Publications

Auditory and visual stimuli presented at intervals of about 300 m sec often produce miss errors in one or the other channel, which result from a bottleneck in a neural circuit associated with executive memory. The present study examined the possibility that cross-modal interference could carry over to performance units that transpire over 3 min or longer. An N-back task performed by 113 undergraduates with simultaneous auditory and visual stimuli was organised into 1-min blocks of 20 trials in 2-back and 3-back conditions. Results showed that impairment of visual processing was more frequent than impairment of auditory processing under …

Low-Dose Stimulant Treatment During Periadolescence In A Fasd Model: Interactions Among The Catecholamines, Victoria Macht

Theses and Dissertations

One of the most common of deficits observed in Fetal Alcohol Spectrum Disorders (FASD) is difficulties with attention. Because attention deficits are commonly treated with stimulants, the impact of d-amphetamine (AMPH) treatment during the juvenile period in an animal model of FASD was examined. A dose-response study first assessed the appropriate dose of AMPH to use. In the dose-response study, therapeutic doses of 0.5, 1.0, and 2.0 mg/kg/day of AMPH were chronically administered to female rats between postnatal days (PD) 26-40. Rats were subjected to an open field test on the first and last day of treatment. The dose of …

Discrepant Attentional Biases Toward Sexual Stimuli, Martin Seehuus

Graduate College Dissertations and Theses

There are at least two types of response to stimuli: an automatic response that happens before conscious thought (a Type 1 response) and a deliberative, intentional response (a Type 2 response). These responses are related to behavior associated with the affective loading of the stimulus presented. Prior research has shown, for example, that a Type 1 tendency to spend more time looking at fear-provoking stimuli is associated with higher levels of general anxiety, while a Type 2 tendency to spend more time looking away from happy faces is associated with higher levels of depressive symptoms. Some stimuli categories elicit mixed …

Visual Attention To Emotional Stimuli In Individuals High On Psychopathic Traits: Evidence From Eye Tracking, Donna M. Crossman

Graduate Dissertations and Theses

Researchers have described psychopaths as callous, cold-hearted individuals who show reduced empathic response to their victims. It is suggested that the inability to identify negative emotions, specifically fear, in individuals is what allows psychopaths to offend/take advantage of other people as they do not recognize the fear in victims that may otherwise deter victimization. This is the first study to examine how non-incarcerated individuals high on psychopathic personality traits process emotions. Additionally, eye-tracking technology was used to provide a more fine-grained assessment of attention. In contrast to hypotheses, the high psychopathic group did not differ from the low psychopathic or …
