Executive Functioning And Lateralized Semantic Priming In Older Adults, Emily J. Helder, Virginia Zuverza-Chavarria, Douglas Whitman

University Faculty Publications and Creative Works

Normal aging is associated with a number of cognitive deficits, including changes in executive functioning. Research suggests that hemispheric asymmetry during certain tasks becomes less pronounced in the elderly, reflected in greater bilateral patterns of cortical activation among older adults. Forty-two younger adults and thirty-five older adults were administered a battery of neuropsychological tests sensitive to frontal functioning. In addition, they completed a lexical decision task to assess lateralized implicit priming at two stimulus onset asynchronies (50 and 750 ms). Results of accuracy and reaction time data support Cabeza’s model of reduced asymmetry in older adults completing a semantic priming …

Encoding Style Of Positive Autobiographical Memories: Relationship To Mood Repair, Memory Functioning, And Depression, Ena Begovic

USF Tampa Graduate Theses and Dissertations

The recall of positive autobiographical memories is an effective strategy for improving negative mood among healthy persons, yet individuals with a history of depression often fail to derive emotional benefits. Depressed and depression-vulnerable individuals also exhibit deficits in their autobiographical memory characteristics. Scholars have implicated deficits during autobiographical memory retrieval as a cause of mood repair and memory impairments, however the role of memory encoding has largely been overlooked. The current study manipulated encoding style to examine subsequent effects on mood repair efficacy, memory characteristics, and memory accuracy. Fifty-five formerly depressed and 68 never-depressed participants were assigned to employ either …

Is The Smartphone A Smart Choice? The Effect Of Smartphone Separation On Executive Functions, Andree Hartanto, Hwajin Yang

Research Collection School of Social Sciences

Despite a huge spike in smartphone overuse, the cognitive and emotional consequences of smartphone overuse have rarely been examined empirically. In two studies, we investigated whether separation from a smartphone influences state anxiety and impairs higher-order cognitive processes, such as executive functions. We found that smartphone separation causes heightened anxiety, which in turn mediates the adverse effect of smartphone separation on all core aspects of executive functions, including shifting (Experiment 1) and inhibitory control and working-memory capacity (Experiment 2). Interestingly, impaired mental shifting was evident regardless of the extent of smartphone addiction, whereas smartphone addiction significantly moderated the negative effect …

Creativity And Cognitive Skills Among Millennials: Thinking Too Much And Creating Too Little, Brice Corgnet, Antonio M. Espín, Roberto Hernán-González

Economics Faculty Articles and Research

Organizations crucially need the creative talent of millennials but are reluctant to hire them because of their supposed lack of diligence. Recent studies have shown that hiring diligent millennials requires selecting those who score high on the Cognitive Reflection Test (CRT) and thus rely on effortful thinking rather than intuition. A central question is to assess whether the push for recruiting diligent millennials using criteria such as cognitive reflection can ultimately hamper the recruitment of creative workers. To answer this question, we study the relationship between millennials' creativity and their performance on fluid intelligence (Raven) and cognitive reflection (CRT) tests. …

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott

Emotion Collection

Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

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 …

The Effect Of Increased Sleep On The Circadian Rhythm Of Salivary Cortisol Concentrations, Mariah Jacqueline Scott

Seton Hall University Dissertations and Theses (ETDs)

Cortisol is a salivary marker for the hypothalamic-pituitary-adrenal axis (HPA) component of the stress response. The activity of the HPA demonstrates a circadian rhythm. It is well known that sleep deprivation increases cortisol concentrations. In this study, we looked at the effect of an increase of one-hour sleep for one month on the circadian rhythm of the HPA.

Eight college subjects (n=8) collected saliva during their normal sleep wake cycle every 4 hours for 24 hours. Saliva collections were repeated after a month of increase of sleep by 1-hour. The subjects also completed demographic forms that asked for age, sex, …

Animal Welfare And Individual Characteristics: A Conversation Against Speciesism, Marc Bekoff, Lori Gruen

Marc Bekoff, PhD

It seems impossible for a human being not to have some point of view concerning nonhuman animal (hereafter animal) welfare. Many people make decisions about how humans are permitted to treat animals using speciesist criteria, basing their decisions on an individual's species membership rather than on that animal's individual characteristics. Although speciesism provides a convenient way for making difficult decisions about who should be used in different types of research, we argue that such decisions should rely on an analysis of individual characteristics and should not be based merely on species membership. We do not argue that the concept of …

Profiles Of Neuropsychological Functioning In Children And Adolescents With Spina Bifida: Associations With Biopsychosocial Predictors And Functional Outcomes, Grayson N. Holmbeck, Rachel M. Wasserman

Psychology: Faculty Publications and Other Works

The current study examined neuropsychological performance among children with spina bifida (SB) to determine biological and functional correlates of distinct “profiles” of cognitive functioning. Methods: A total of 95 children with SB myelomeningocele (ages, 8–15 years) completed a neuropsychological assessment battery. Hierarchical and non-hierarchical cluster analyses were used to identify and confirm a cluster solution. Hypothesized predictors of cluster membership included lesion level, number of shunt surgeries, history of seizures, age, ethnicity, socio-economic status, and family stress. Outcomes included independence, academic success, expectations for the future, and quality of life. Results: Ward’s cluster method indicated a three-cluster solution, and was …

Cooperation And Facets Of Psychological Collectivism As Antecedents Of Team Mental Model Similarity, Neal Benoit Outland

College of Science and Health Theses and Dissertations

This thesis investigated the role of facets of trait psychological collectivism (Preference, Reliance, Concern, and Goal-Priority) and the personality trait cooperativeness in the development of Team Mental Models. Team Mental Models (TMMs) are shared representations of a work team’s context that aid a team in directing behaviors and coordinating actions. I utilized Marks, Mathieu, and Zaccaro’s (2001) taxonomy of team processes to explicate and test a model detailing the role of composition in TMM development. Data were collected from 35 teams of 5 individuals who completed a computer simulation in which the team interdependently replicated pictures using blocks. Multiple regression …

Orca Behavior And Subsequent Aggression Associated With Oceanarium Confinement, Robert Anderson, Robyn Waayers, Andrew Knight

Theory of Mind Collection

Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may apply, or in captivity, where access is constrained for commercial and safety reasons. From 1979 to 1980, however, we were able to interact with juvenile orcas in an unstructured way at San Diego’s SeaWorld facility. We observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, …

The Acute Effects Of Nicotine And Exercise On Working Memory, Steven Guirguis

Electronic Thesis and Dissertation Repository

Nicotine, an alkaloid found in tobacco leaves, has been used by humans for its psychoactive properties for centuries. Specifically, nicotine has been consistently shown to improve cognitive performance (Heishman, Kleykamp, & Singleton, 2010). Similar effects also have been shown with exercise (Chang, Labban, Gapin, & Etnier, 2012). The purpose of the present study was to examine whether a 20 min bout of moderate-intensity exercise enhances cognitive performance (working memory) as effectively as 4 mg of NICORETTE® gum in a non-smoker population. Twenty-three non-smokers (M age = 25.87; 13 female) underwent a three-week randomized counterbalanced procedure. The N-Back Task was used …

The Interaction Of Crystallized And Fluid Abilities In Aging And Speech Perception, Avanti Dey

Arts & Sciences Electronic Theses and Dissertations

In a series of studies, I examined the degree to which fluid and crystallized abilities contribute to and interact during speech perception. During the aging process, crystallized abilities (e.g., linguistic and word knowledge) are largely preserved, while fluid abilities involved in the online manipulation of information (e.g., working memory and inhibitory control) decline with age. Importantly, these two components are critical for successful speech perception and comprehension. While prior research has proposed that older adults rely on crystallized knowledge to compensate for cognitive deficits in difficult listening conditions, this hypothesis has not been directly tested. Younger and older adults completed …

Genetic Risk For Increased Oxidative Stress In The Aging Brain:Implications For White Matter Integrity And Cognition, Lauren Salminen

Dissertations

Oxidative stress is a key mechanism of the aging process that can cause damage to brain white matter and cognitive functions. Allele variations of two polymorphisms (SOD2, CAT -262) have been associated with abnormalities in antioxidant enzyme activity, suggesting a risk for enhanced oxidative damage to brain white matter and cognition among older individuals with these genetic mutations. The present study utilized diffusion tensor imaging (DTI) and neuropsychological assessment to compare differences in microstructural white matter integrity and cognitive performance among 96 older adults (age 50-85) with and without genetic risk factors of SOD2 (rs4880) and CAT -262 (rs1001179). Results …

Constructive And Deconstructive Tool Modification By Chimpanzees (Pan Troglodytes), Amanda E. Bania, Stephany Harris, Hannah R. Kinsley, Sarah T. Boysen

Sarah Boysen, PhD

Nine chimpanzees (Pan troglodytes) were tested for their ability to assemble or disassemble the appropriate tool to obtain a food reward from two different apparatus. In its deconstructed form, the tool functioned as a probe for one apparatus. In its constructed form, the tool functioned as a hook, appropriate for a second apparatus. Each subject completed four test trials with each apparatus type. Tool types were randomized and counter-balanced between the two forms. Results demonstrated that adult and juvenile chimpanzees (N = 7) were successful with both tool types, while two infant chimpanzees performed near chance. Off-line video analyses revealed …

Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt

Electronic Theses and Dissertations

The aim of the current dissertation was to investigate the mechanisms that contribute to the emergence of causal perception in infancy. Previous research suggests that the experience of self-produced causal action may be necessary to promote the development of causal perception (Rakison & Krogh, 2012). The goal of the current study was two-fold: (1) to further explore the roles of self-produced action, haptic, proprioceptive and visual information, and parental interaction on young infants’ understanding of causality. To assess the impact of these factors on infants’ causal learning, 4½-month-olds were randomly assigned to one four conditions. Three of the conditions (Active …

Reflections: Students' Tribute To Stan Kuczaj (1950-2016), Mark J. Xitco, Heather M. Hill, Marie Trone, Rachel T. Walker, Kymbr Wright, Radhika Macheka, Andrew J.

Frick, Lisa Lauderdale, Kelsey Moreno, Kendal Smith, Audra Ames, Ali Taylor, Malin Lilley, Briana Cappiello, Riley Macgregor, Jennifer Vonk, Michael Beran

Psychology Faculty Publications

On April 14th, 2016, Animal Behavior and Cognition lost its Editor-in-Chief. But the scientific community and the friends and colleagues of Stanley ‘Stan’ Kuczaj III lost so much more. As many know, Stan began his career in Developmental Psychology, making enormous contributions in the area of language development, but became best known for his many innovative contributions in the area of marine mammal behavior. Stan founded Animal Behavior and Cognition because he was deeply passionate about research with a broad range of topics concerning animal behavior, animal cognition, and animal welfare. He was equally passionate about the idea that science …

In Praise Of Fishes: Précis Of What A Fish Knows (Balcombe 2016), Jonathan Balcombe

Animal Sentience

Our relationship to fishes in the modern era is deeply problematic. We kill and consume more of them than any other group of vertebrates. At the same time, advances in our knowledge of fishes and their capabilities are gaining speed. Fish species diversity exceeds that of all other vertebrates combined, with a wide range of sensory adaptations, some of them (e.g., geomagnetism, water pressure and movement detection, and communication via electricity) alien to our own sensory experience. The evidence for pain in fishes (despite persistent detractors) is strongly supported by anatomical, physiological and behavioral studies. It is likely that fishes …

Effects Of Age, Task Type, And Information Load On Discrimination Learning, Morgan E. Brown

Masters Theses & Specialist Projects

The feature positive effect (FPE) is a phenomenon in discrimination learning by which learning occurs more quickly when the presence (Feature positive; FP), rather than absence (Feature negative; FN) of a stimulus indicates a response should be made. Although the FPE has been extensively corroborated, a reversal, or feature negative effect (FNE), has been found when a target stimulus comes from a smaller set of stimuli (Fiedler, Eckert, & Poysiak, 1988). Age differences in FP and FN learning indicate that older adults perform more poorly than young adults on both FP and FN tasks, and are likely related to decline …

Individual Differences In Working Memory Capacity Predicts Responsiveness To Memory Rehabilitation After Traumatic Brain Injury, Joshua Sandry, Kathy S. Chiou, John Deluca, Nancy D. Chiaravalloti

Design Post hoc analysis of a randomized controlled clinical trial designed to treat learning and memory impairment after traumatic brain injury (TBI): 2 × 2 between-subjects quasiexperimental design (2 [group: treatment vs control] × 2 [WMC: high vs low]). Setting Nonprofit medical rehabilitation research center. Participants Participants (N=65) with moderate to severe TBI with pre- and posttreatment data. Interventions The treatment group completed 10 cognitive …

Laterality Influences Cognitive Performance In Rainbowfish Melanotaenia Duboulayi, Anne-Laurence Bibost, Culum Brown

Culum Brown, PhD

Cerebral lateralization has been suggested to convey a selective advantage to individuals by enhancing their cognitive abilities. Few, however, have explicitly compared the cognitive ability of animals with strongly contrasting laterality. Here, we examined the influence of laterality on learning performance in the crimson spotted rainbowfish, Melanotaenia duboulayi, using a classical conditioning paradigm. We also compared the learning ability of wild caught and captive-reared fish to examine the influence of rearing environment on cognitive performance. Laterality was established by observing which eye fish preferred to use while viewing their mirror image. Subjects were then conditioned to associate the appearance of …

Meditation And Chocolate: Comparing Their Effects On Cognitive Abilities, Ryan Dyck

Undergraduate Psychology Research Methods Journal

Numerous studies have been conducted on the effects of meditation on long-term meditators. This current study aims to test the immediate effects of meditation on cognition. It is hypothesized that meditation will have a significant effect on cognition in comparison to the control of chocolate. In order to test this hypothesis participants were subject to two conditions: a meditation condition and a chocolate condition. After each condition participants were given a cognition test designed to test their reading comprehension and math skills. Using a related samples t-test I conclude that meditation does not have a significant effect on cognition using …

Genetic Moderators Of Cognitive Decline In The Health And Retirement Study, Shannon K. Runge

USF Tampa Graduate Theses and Dissertations

The current dissertation used a gene x environment (G x E) approach to examine the independent and interactive effects of specific genetic variants and participation in physical and cognitive/social activities (PA and CSA) on cognitive performance in 4,764 participants of the Health and Retirement Study. Using three-wave data, three sets of multi-level growth models were conducted to examine baseline, longitudinal, and interactive effects of genotype (i.e., ApoE, COMT, and BDNF) and CSA/PA on performance across five cognitive measures: immediate, delayed and total word recall, and serial 7s and backwards counting.

At baseline, the ApoE ε4 allele predicted …

Language And Cognition: Insight From Exceptional Cases, Anna Snyder

Senior Honors Theses

The understanding of the world in the human mind is accomplished through cognitive processing and articulated through linguistic processing. Undoubtedly, there is a significant connection between language and cognition because of how intricately they work together to create and express meaning. Researchers from a variety of fields have sought to discover the specifics of these domains to determine what kind of relationship exists between them and how the involvement between language and cognition should be best represented. Though they obviously interact, the different characteristics of each domain provide evidence that linguistic processes and cognitive processes may be distinct. Rather than …

Category Learning In Older Adulthood: A Study Of The Shepard, Hovland, And Jenkins (1961) Tasks., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Shepard, Hovland, and Jenkins (1961) examined the categorization abilities of younger adults using tasks involving single-dimensional rule learning, disjunctive rule learning, and family resemblance learning. The current study examined category learning in older adults using this well-known category set. Older adults, like younger adults, found category tasks with a single relevant dimension the easiest to learn. In contrast to younger adults, older adults found complex disjunctive rule-based categories harder to learn than family resemblance based categories. Disjunctive rule-based category learning appeared to be the most difficult for older adults to learn because this category set placed the heaviest demands on …

General Mathematical Ability Predicts Pasat Performance In Ms Patients: Implications For Clinical Interpretation And Cognitive Reserve, Joshua Sandry, Jessica Paxton, James F. Sumowski

Department of Psychology Faculty Scholarship and Creative Works

Objectives: The Paced Auditory Serial Addition Test (PASAT) is used to assess cognitive status in multiple sclerosis (MS). Although the mathematical demands of the PASAT seem minor (single-digit arithmetic), cognitive psychology research links greater mathematical ability (e.g., algebra, calculus) to more rapid retrieval of single-digit math facts (e.g., 5+6=11). The present study evaluated the hypotheses that (a) mathematical ability is related to PASAT performance and (b) both the relationship between intelligence and PASAT performance as well as the relationship between education and PASAT performance are both mediated by mathematical ability. Methods: Forty-five MS patients were assessed using the Wechsler Test …

Incremental Validity Of Useful Field Of View Subtests For The Prediction Of Instrumental Activities Of Daily Living, Frederik Aust, Jerri D. Edwards

Aging Studies Faculty Publications

Introduction: The Useful Field of View Test (UFOV®) is a cognitive measure that predicts older adults’ ability to perform a range of everyday activities. However, little is known about the individual contribution of each subtest to these predictions, and the underlying constructs of UFOV performance remain a topic of debate.

Method: We investigated the incremental validity of UFOV subtests for the prediction of Instrumental Activities of Daily Living (IADL) performance in two independent datasets, the SKILL (n = 828) and ACTIVE (n = 2426) studies. We then explored the cognitive and visual abilities assessed by UFOV …

Should Fish Feel Pain? A Plant Perspective, František Baluška

Animal Sentience

Key (2016) claims fish that fish do not feel pain because they lack the necessary neuronal architecture: their responses to noxious stimuli, according to Key, are executed automatically without any feelings. However, as pointed out by many of his commentators, this conclusion is not convincing. Plants might provide some clues. Plants are not usually thought to be very active behaviorally, but the evidence suggests otherwise. Moreover, in stressful situations, plants produce numerous chemicals that have painkilling and anesthetic properties. Finally, plants, when treated with anesthetics, cannot execute active behaviors such as touch-induced leaf movements or rapid trap closures after localizing …
