Understanding Across The Senses: Cross-Modal Studies Of Cognition In Cetaceans, Jason N. Bruck, Adam A. Pack

Faculty Publications

Cross-modal approaches to the study of sensory perception, social recognition, cognition, and mental representation have proved fruitful in humans as well as in a variety of other species including toothed whales in revealing equivalencies that suggest that different sensory stimuli associated with objects or individuals may effectively evoke mental representations that are, respectively, object based or individual based. Building on established findings of structural equivalence in the form of spontaneous recognition of complex shapes across the modalities of echolocation and vision and behavior favoring identity echoic–visual cross-modal relationships over associative echoic–visual cross-modal relationships, examinations of transitive inference equivalencies from initially …

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik

Faculty Publications

While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same …

Ugandan Adolescents’ Descriptive Gender Stereotypes About Domestic And Recreational Activities, And Attitudes About Women, Flora Farago, Natalie Eggum-Wilkens, Linlin Zhang

Faculty Publications

In Eastern Uganda, 201 adolescents aged 11- to 17-years old (48% girls; M_age = 14.62) answered close- and open-ended questions about gender stereotypes of domestic and recreational activities and gender-role attitudes about women’s behavior, rights, and roles. Adolescents answered questions such as “who is more likely to . . .?” assessing descriptive stereotypes (i.e., stereotype knowledge) and questions such as “is it ok for women to . . .?” assessing prescriptive stereotypes (i.e., stereotype endorsement) about gender roles. Data were analyzed via descriptive statistics, correlations, and thematic coding. Findings indicate that Ugandan adolescents were fairly egalitarian in some domains …

Cognitive Impairments And Self-Reported Sleep In Early-Stage Parkinson’S Disease With Versus Without Probable Rem Sleep Behavior Disorder, Jonathan Trout, Taylor Christiansen, M. Brooks Bulkley, Jared J. Tanner, Christopher N. Sozda, Dawn Bowers, Daniel Kay

Faculty Publications

Parkinson’s disease (PD) is associated with cognitive and sleep impairments. The presence of rapid eye movement (REM) sleep behavior disorder (RBD) symptoms may represent a worse disease prognosis for PD individuals. We investigated cognitive functioning and self-reported sleep in early-stage PD individuals with (n = 19) or without (n = 31) probable RBD. Probable RBD was defined as >5 on the REM Sleep Behavior Disorder Screening Questionnaire. Inhibition, visuospatial cognitive abilities, working memory, sustained visual attention, verbal fluency, and episodic memory were assessed. Sleep impairments were assessed using the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and …

Both Facts And Feelings: Emotion And News Literacy, Susan Currie Sivek

Faculty Publications

News literacy education has long focused on the significance of facts, sourcing, and verifiability. While these are critical aspects of news, rapidly developing emotion analytics technologies intended to respond to and even alter digital news audiences’ emotions also demand that we pay greater attention to the role of emotion in news consumption. This essay explores the role of emotion in the “fake news” phenomenon and the implementation of emotion analytics tools in news distribution. I examine the function of emotion in news consumption and the status of emotion within existing news literacy training programs. Finally, I offer suggestions for addressing …

Toxoplasma Gondii Moderates The Association Between Multiple Folate-Cycle Factors And Cognitive Function In U.S. Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (T. gondii) is a microscopic, apicomplexan parasite that can infect muscle or neural tissue, including the brain, in humans. While T. gondii infection has been associated with changes in mood, behavior, and cognition, the mechanism remains unclear. Recent evidence suggests that T. gondii may harvest folate from host neural cells. Reduced folate availability is associated with an increased risk of neurodevelopmental disorders, neurodegenerative diseases, and cognitive decline. We hypothesized that impairment in cognitive functioning in subjects seropositive for T. gondii might be associated with a reduction of folate availability in neural cells. We analyzed data from the third …

Progressive Deterioration Of Thalamic Nuclei Relates To Cortical Network Decline In Schizophrenia, Derin J. Cobia, Matthew J. Smith, Ilse Salinas, Charlene Ng, Mohktar Gado, John G. Csernansky, Lei Wang

Faculty Publications

Thalamic abnormalities are considered part of the complex pathophysiology of schizophrenia, particularly the involvement of specific thalamic nuclei. The goals of this study were to: introduce a novel atlas-based parcellation scheme for defining various thalamic nuclei; compare their integrity in a schizophrenia sample against healthy individuals at baseline and follow-up time points, as well as rates of change over time; examine relationships between the nuclei and abnormalities in known connected cortical regions; and finally, to determine if schizophreniarelated thalamic nuclei changes relate to cognitive functioning and clinical symptoms. Subjects were from a larger longitudinal 2-year follow-up study, schizophrenia (n=20) and …

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 …

Association Between Toxocariasis And Cognitive Function In Young To Middle-Aged Adults, Bruce L. Brown, Lance D. Erickson, Shawn D. Gale, Andrew Berrett, Dawson W. Hedges

Faculty Publications

The ascarid nematodes Toxocara canis (Werner, 1782) and Toxocara cati (Schrank, 1788) may infect humans resulting in toxocariasis. A prior study associated species of Toxocara Stiles, 1905 with cognitive deficits in children. To determine if a similar association between toxocariasis and cognition exists in adults, we analysed a large dataset from the United States’ Center for Disease Control’s National Health and Nutrition Examination Survey. We used linear-regression and multivariate models to examine the association between toxocariasis as assessed by the presence of anti-Toxocara IgG antibodies and three measures of cognitive function – simple reaction time (SRT), symbol-digit substitution (SDS) and …

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 …
