Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when …

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …

Cognitive Profiles And The Impact Of Medication On Children With Attention Deficit Hyperactivity Disorder, Lucy J. Wimpenny

PCOM Psychology Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequently diagnosed disorders in children and adolescents. Individuals with ADHD often display behavioral symptoms, including inattention and/or impulsivity, which can also lead to struggles in the school setting. Current research has suggested that deficits in processing speed and working memory are common in individuals diagnosed with ADHD and are often seen on measures of cognitive ability. Positive outcomes have been associated with the use of psychostimulant medication to treat the symptoms of ADHD, although little research has supported this form of treatment to improve cognitive functioning in individuals diagnosed with …

Introduction To Special Issue: Dementia And Music, Andrea R. Halpern, Isabelle Peretz, Lola L. Cuddy

Faculty Journal Articles

This special issue follows two previous special issues on music and neurological disorders (April 2008, Volume 23/Issue 4 and April 2010, Volume 25/Issue 4). Like its predecessors, the issue presents studies employing a patient-based approach to music perception, cognition, and emotion. Whereas the earlier issues dealt with acquired and congenital disorders and impairments, the present issue focuses on dementia, primarily on its most common form, Alzheimer's disease (AD).

Association Between C-Reactive Protein And Cognitive Deficits In Elderly Men And Women: A Meta-Analysis, Bruce L. Brown, Dawson W. Hedges, Thomas J. Farrer

Faculty Publications

Abstract

Background: Certain risk factors for cognitive decline appear modifiable. A potentially modifiable marker of inflammation, C-reactive protein may be associated with cognitive deficits, although not all studies have found a relationship between C-reactive protein and cognitive ability. Further, few research papers have examined whether gender may affect any association between C-reactive protein and cognitive deficit.

Methods: To better understand the association between C-reactive protein, cognitive deficit, and gender in elderly people, we meta-analyzed cross-sectional studies that reported cognitive ability assessed by the Mini-Mental State Examination or an equivalent measure, C-reactive protein concentrations, and gender.

Results: While we identified no …

The Effect Of Spiritualism On The Cognitive Functions On Learning And Memory, Carla Antonieta Farcello

McNair Poster Presentations

Last summer I conducted a pilot study which researched whether better working memory would be documented among an experimental group (individuals who report being spiritual) as compared to the control group (individuals who report being non-spiritual).Total scores showed a significantly higher sense of spiritualism among the spiritual participants vs. the non spiritual participants (p < .001) along with a significant improvement in working memory for spiritual participants vs. non spiritual participants (p = .027). The results of this study documented significantly better performance on a task measuring emotional learning and memory among individuals who reported being spiritual as opposed to individuals who reported being non-spiritual. These findings build on prior studies suggesting the effect of positive emotions on broadening cognitive processes (Strauss & Allen, 2003).

My current study is building on what my prior findings have suggested and studies the effect of spiritualism on the cognitive functions of learning and memory. In addition to the Daily Spiritual Experiences Scale (DSES) used in the pilot study, I am including the Spirituality Index …

How Selective Is Social Learning In Dolphins?, Stan A. Kuczaj Ii, Deirdre Yeater, Lauren Highfill

Psychology Faculty Publications

Social learning is an important aspect of dolphin social life and dolphin behavioral development. In addition to vocal social learning, dolphins discover behaviors for foraging, play, and social interactions by observing other members of their social group. But dolphins neither indiscriminately observe nor mindlessly mimic other dolphins. To the contrary, dolphin calves are quite selective in their choices of who to observe and/or imitate. Calves are most likely to learn foraging behaviors from their mothers, but they are more likely to watch and reproduce the play behaviors of other calves than the play behaviors of adult dolphins (including their mothers). …

Visual Attention To Erotic Stimuli In Androphilic Male-To-Female Transsexuals, Sarah A. Akhter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study investigated sex differences in visual attention to erotic stimuli by comparing three groups of individuals: heterosexual men, heterosexual women, and androphilic MtF transsexuals. Twenty men, 20 women and 13 MtF transsexuals were shown 10 split-screen slides, each featuring one nude erotic photo of a man shown on half of the screen and one nude erotic photo of a woman shown on the other half of the screen. Eye movements were tracked as participants viewed the slides. All participants were heterosexual (Kinsey 0-1) relative to gender identity, thus erotic targets for natal men were nude women in the …

Cognitive Bias Modification: Past Perspectives, Current Findings, And Future Applications, Paula T. Hertel, A. Mathews

Psychology Faculty Research

Research conducted within the general paradigm of Cognitive Bias Modification (CBM) reveals that emotional biases in attention, interpretation, and memory are not merely associated with emotional disorders but contribute to them. After briefly describing research on both emotional biases and their modification, we examine similarities between CBM paradigms and older experimental paradigms used in research on learning and memory. We also compare the techniques and goals of CBM research to other approaches to understanding cognition/emotion interactions. From a functional perspective, the CBM tradition reminds us to use experimental tools to evaluate assumptions about clinical phenomena and more generally, about causal …

Cerebral Lateralization Determines Hand Preferences In Australian Parrots, Culum Brown, Maria Magat

Sentience Collection

Individual preference for the use of one limb over the other to explore the environment or manipulate objects is common trait among vertebrates. Here, we explore the hypothesis that limb preference is determined by the engagement of a particular cerebral hemisphere to analyse certain stimuli. We recorded the eye and foot preferences of 322 individuals from 16 species of Australian parrots while investigating potential food items. Across all species, eye preferences explained 99 per cent of the variation in foot use in Australian parrots. The vast majority of species showed significant relationships between eye and foot preferences at the population …

The Effect Of Endpoint Knowledge On Dot Enumeration, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study attempts to extend the principle tenets of the Overlapping Waves Theory (Siegler, 1996), a framework designed to explain the progression of trends in cognitive development, to adult participants’ performance in a dot enumeration task. Literature in the 0-100 number line estimation task (Siegler & Booth, 2004, Ashcraft & Moore, 2011) has revealed a pervasive trend in child estimation such that young children (especially those in kindergarten) respond with a logarithmic line of best fit, while children at the third grade and above overwhelmingly respond with linear estimates to this same range of numbers. A similar developmental trend is …

Does Physical Activity Influence Semantic Memory Activation In Amnestic Mild Cognitive Impairment?, J. Carson Smith, Kristy A. Nielson, John L. Woodard, Michael Seidenberg, Matthew D. Verber, Sally Durgerian, Piero Antuono, Alissa M. Butts, Nathan C. Hantke, Melissa A. Lancaster, Stephen M. Rao

Psychology Faculty Research and Publications

The effect of physical activity (PA) on functional brain activation for semantic memory in amnestic mild cognitive impairment (aMCI) was examined using event-related functional magnetic resonance imaging during fame discrimination. Significantly greater semantic memory activation occurred in the left caudate of High- versus Low-PA patients, (P=0.03), suggesting PA may enhance memory-related caudate activation in aMCI.

Executive Function Profiles In Pediatric Traumatic Brain Injury, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traumatic brain injury is a common cause of disability and death among children in the United States. Insult to the frontal and temporal lobes are frequent in closed head brain injury. Cognitive deficits in a variety of domains are common sequelae of brain trauma. In many cases, trauma to the frontal and temporal lobe regions engender prominent deficits in higher-order cognitive processing, memory, and attention.

Higher-order cognitive processing, or Executive Functions are the grouping of cognitive processes necessary for organization of thoughts and activities, attending to the activities, prioritizing tasks, managing time efficiently, and making decisions (Alvarez & Emory, 2006; …

Common And Distinct Mechanisms Of Cognitive Flexibility In Prefrontal Cortex, Chobok Kim, Nathan F. Johnson, Sara E. Cilles, Brian T. Gold

Neuroscience Faculty Publications

The human ability to flexibly alternate between tasks represents a central component of cognitive control. Neuroimaging studies have linked task switching with a diverse set of prefrontal cortex (PFC) regions, but the contributions of these regions to various forms of cognitive flexibility remain largely unknown. Here, subjects underwent functional brain imaging while they completed a paradigm that selectively induced stimulus, response, or cognitive set switches in the context of a single task decision performed on a common set of stimuli. Behavioral results indicated comparable reaction time costs associated with each switch type. Domain-general task-switching activation was observed in the inferior …

Loving The World And Our Children Enough--Nurturing Decidedly Different Scientifc Minds, By Design, Stephanie Pace Marshall

Publications & Research

Wise world-shaping and problem-solving requires that we and our children think in decidedly different, integral and wise ways. This transformation requires a fundamental shift in consciousness and the emergence of global minds that can creatively live into a new worldview of an interconnected planet and a sustainable and interdependent human family. "The fullness of our humanity and the sustainability of our planet rest with the nurturing of decidedly different minds."

The Effect Of Strategies On Relieving Initial And Recurring Tip Of The Tongue States, Cheryl Elizabeth Emery

Theses Digitization Project

One of the most common forms of memory failure is the phenomenon known as "tip-of-the-tongue" (TOT) where you can't quite articulate a particular word even though you know that you know it. Strategies for resolving this phenomenon were explored in two experiments. This thesis explored the effectiveness of different strategies for resolving the TOT experience.

Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews

Sentience Collection

We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.

The Canine Sand Maze: An Appetitive Spatial Memory Paradigm Sensitive To Age-Related Change In Dogs, Hannah Salvin, Paul D. Mcgreevy, Perminder S. Sachdev, Michael Valenzuela

Spatial Cognition Collection

Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter circular pool was filled with a sand and powdered food reward mix to a depth of 10 cm. Dogs were given 4 habituation and 16 learning trials which alternated a food reward being half (control trials) or fully-buried (acquisition trials) in a fixed location. After a …

Effects Of Bilingualism On Goal Representation And Maintenance, Amina Saadaoui

Theses Digitization Project

The main focus of this study was to examine whether the bilingual advantage in cognitive control is due to the bilinguals' ability to represent and maintain goal information in working memory. Cognitive control, also referred to as executive control, is the ability to inhibit one cognitive task while executing another task.

The Architecture Of Multitasking : Expanding A Structural Model, Eugene J. Trombini

Legacy Theses & Dissertations (2009 - 2024)

The aim of this study was to create and validate a structural model of multitasking performance based on the characteristics of multitasking situations outlined by Delbridge (2000). A model is put forth suggesting that the observed relationships between multitasking performance and other variables is determined partly by the prominence of three structural characteristics of multitasking situations (time urgency, task switching, and uncertainty). The observed relationships between multitasking performance and other variables is explained in terms of perceived stress. Specifically, it was hypothesized that an individual's standing on certain variables would be associated with better management of the stress that stems …

The Effect Of Response Format On Syllogistic Reasoning, Adam S. Billman

Calvert Undergraduate Research Awards

This study examined the effect of response format on the conclusions drawn in a categorical reasoning task. In Experiment 1, participants were required to respond in either a multiple-choice format or were required to produce their own conclusion (without any choices presented). In the multiple-choice task, people responded with a wider variety of conclusions, more No Valid Conclusion responses, and had a smaller forward bias. In terms of theoretical predictions, Mental Model Theory was better supported in the multiple-choice condition and more conclusions corresponded with initial models in the production task while more conclusions corresponded with alternative models in the …

Information Overload... @Your Library, Louann Blocker

Georgia Library Quarterly

The article deals with information overload. Nicholas Carr in his book "The Shallows: What the Internet is Doing to Our Brains" explains the process of cognitive overload. Carr also explains how Internet, cell phones or electronic mail messages distract people from contemplation. Carr stresses that the current lifestyle is eroding a person's capacity for deep, sustained, perception attention. The term information overload is defined by Kathryn Hensiak. Tips on controlling the information environment are presented.

Readers’ Knowledge Of Functional Devices, Hung-Tao Chen

University of Kentucky Master's Theses

Various writing devices are designed to serve specialized purposes or “functions” to aid readers in their processing of a text. For example, an index lists important topics in the book and allows the readers to quickly locate the pages relevant to a particular topic. The purpose of this study was to learn what mature readers know about various functional devices. Two experiments were conducted to learn what readers know about functional devices in texts. Experiment 1 investigated readers’ knowledge about functional writing devices and Experiment 2 examined readers’ beliefs about the relevance of functional writing devices in various reading situations. …

Visual Search For Smoking Stimuli: Detection And Distraction, Jason A. Oliver

USF Tampa Graduate Theses and Dissertations

Extensive research has shown that the attentional systems of addicted individuals are biased towards drug-related stimuli, but despite several decades of effort these results have frequently been inconsistent. Though commonly believed to result from addiction and dependence, cognitive research would suggest that frequent exposure to drug-related stimuli could affect the attentional processing of drug-related cues even if no actual drug use occurs. The present investigation examined attentional bias for smoking cues using a novel visual search paradigm amongst smokers currently in nicotine withdrawal and fully satiated smokers, as well as a non-smoker control group. Variables related to smoking behavior, as …

Prospective Evaluation Of A Cognitive Vulnerability-Stress Model For Depression: The Interaction Of Schema Self-Structures And Negative Life Events., Pamela M Seeds, David J A Dozois

Psychology Publications

This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regression analyses, controlling for initial depression, indicated that more tightly interconnected negative content was associated with greater elevations in depressive symptoms following the occurrence of life events. More diffusely interconnected positive content for interpersonal self-referent information also interacted with life events to predict depressive symptoms. Cognitive organization dimensions showed moderate to high stability across …

Prenatal Undernutrition And Cognitive Function In Late Adulthood, Susanne R. De Rooij, Hans Wouters, Julie E. Yonker, Rebecca C. Painter

University Faculty Publications and Creative Works

At the end of World War II, a severe 5-mo famine struck the cities in the western part of The Netherlands. At its peak, the rations dropped to as low as 400 calories per day. In 1972, cognitive performance in 19-y-old male conscripts was reported not to have been affected by exposure to the famine before birth. In the present study, we show that cognitive function in later life does seem affected by prenatal undernutrition. We found that at age 56 to 59, men and women exposed to famine during the early stage of gestation performed worse on a selective …

Cognitive And Psychiatric Predictors To Psychosis In Velocardiofacial Syndrome: A 3-Year Follow-Up Study, Kevin M. Antshel, Robert J. Shprintzen, Wanda Fremont, Anne Marie Higgins, Stephen V. Faraone, Wendy R. Kates

Communication Disorders Faculty Publications

Objective: To predict prodromal psychosis in adolescents with velocardiofacial syndrome (VCFS). Method: 70 youth with VCFS, 27 siblings of youth with VCFS and 25 community controls were followed from childhood (Mean age = 11.8 years) into mid-adolescence (mean age 15.0 years). Psychological tests measuring intelligence, academic achievement, learning/memory, attention and executive functioning as well as measures of parent and clinician ratings of child psychiatric functioning were completed at both time point. Results: Major depressive disorder, oppositional defiant disorder, and generalized anxiety disorder diagnoses increased in the VCFS sample. With very low false positive rates, the best predictor of adolescent prodromal …

Adolescent Triangulation Into Parental Conflicts: Longitudinal Implications For Appraisals And Adolescent-Parent Relations, Gregory M. Fosco, John H. Grych

Psychology Faculty Research and Publications

Although triangulation into parental conflict is a risk factor for child and adolescent maladjustment, little is known about how triangulation affects adolescents’ functioning or the factors that lead children to be drawn into parental disagreements. This prospective study examined the relations between triangulation, appraisals of conflict, and parent-child relations in a sample of 171 adolescents, ages 14 to 19 years, at 2 time points. Cross-lagged path analyses revealed that youths who experienced greater threat in response to conflict reported increases in triangulation over time, and triangulation was associated with increased self-blame and diminished parent-adolescent relations. This study highlights links between …

Implicit Affect And Alcohol Outcome Expectancies, John M. Ray

USF Tampa Graduate Theses and Dissertations

Expectancy theory provides a useful framework within which to examine the link between cognitive representations of anticipated alcohol related outcomes and affective processes that ought to shape behavior at the level of implicit, or automatic, processing. The role of affect in alcohol expectancies is an important one as it reflects the approach-avoid contingency associated with reward learning presumed to underlie addictive processes. This study examined the relationship between affect and expectancy operation by using suboptimally presented alcohol related cues to prime affectively congruent evaluations of otherwise unrelated targets. Hypotheses predicted that drinkers who reported higher positive and arousing expectancies for …
