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 …

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 …

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 …

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, …

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 …

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

Interventions The treatment group completed 10 cognitive …

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 …

Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott

Learning Ability Collection

Variation in common personality traits, such as boldness or exploration, is often associated with risk–reward trade–offs and behavioural flexibility. To date, only a few studies have examined the effects of consistent behavioural traits on both learning and cognition. We investigated whether certain personality traits (‘exploration’ and ‘sociability’) of individuals were related to cognitive performance, learning flexibility and learning style in a social ungulate species, the goat (Capra hircus). We also investigated whether a preference for feature cues rather than impaired learning abilities can explain performance variation in a visual discrimination task. We found that personality scores were consistent …

Navigating The Decision Space: Shared Medical Decision Making As Distributed Cognition, Katherine D. Lippa, Markus Alexander Feufel, F. Eric Robinson, Valerie L. Shalin

Psychology Faculty Publications

Despite increasing prominence, little is known about the cognitive processes underlying shared decision making. To investigate these processes, we conceptualize shared decision making as a form of distributed cognition. We introduce a Decision Space Model to identify physical and social influences on decision making. Using field observations and interviews, we demonstrate that patients and physicians in both acute and chronic care consider these influences when identifying the need for a decision, searching for decision parameters, making actionable decisions Based on the distribution of access to information and actions, we then identify four related patterns: physician dominated; physician-defined, patient-made; patient-defined, physician-made; …

Folate And Inflammatory Markers Moderate The Association Between Helicobacter Pylori Exposure And Cognitive Function In Us Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Background: Helicobacter pylori(H. pylori) infection is associated with cogni-tive deficits in humans, an association potentially mediated or moderated byfolate concentration or inflammation.Materials and

Methods: We used the National Health and Nutrition Exami-nation Survey (NHANES) datasets to examine whether folate concentrationor inflammation mediates or moderates the relationship betweenH. pyloriand cognitive function. Models were performed using linear, Poisson, andzero-inflated Poisson regression, and we performed separate analyses forgroups aged 20–59 and 60–90 years with sample sizes ranging from 700 to1700.Results:We did not find evidence of mediation in either age group. In the20- to 59-year group, interactions betweenH. pyloriand ferritin (pvaluesranging from .004 to …
