What it takes to speak two languages: Lexical representation and processing in bilingual language production
Friday, April 6, 2018
Speaking seems effortless to most, yet is extremely complex. Even the simplest utterance involves compiling a message to communicate, computing a grammatical structure, selecting the words that best express the message, and retrieving the sounds that make those words up. Bilingual speakers face additional complexities: they have more words to select from (across their two languages), they need more effort to retrieve non-dominant language words, and they need to avoid wrong-language slips of the tongue, or else they may not be understood. In this talk, I will discuss findings relevant to how bilingual speakers select the words they need, and what help they get in the process: Language control mechanisms help prioritize non-dominant-language production, internal monitoring mechanisms help detect wrong-language intrusions, and reusing the words of one’s conversational partner (a phenomenon known as alignment) eases the complexity of word choice.
Organization of Interaction of Functional Brain Networks
March 21, 2018
Recent advances in neuroscience have transformed our approach in mapping the human brain. Rather than relying on a simplistic view of human brain function where each region of the brain is specialized for a single function, medical imaging technology has provided a more complete understanding of the brain as an integrated system of interconnected networks that interact dynamically to carry out a given task. Human cognition and behavior involves the coordination of activity across large-scale brain networks which can be identified using function magnetic imaging resonance (fMRI). Here, we examine the relationships between these brain networks at rest and during cognitive control processing in healthy adults and in schizophrenia.
Prejudice towards Arabs/Middle Easterners
November 29, 2017 at 11:00-12:15
Prejudice towards Arab/Middle Easterners has existed in this country ever since the first immigrants settled in the United States. Yet, despite the current climate, relatively little is known about this pan-ethnic minority group that is plagued with prejudice and discrimination. In this colloquium presentation, I will discuss the predictors of prejudice towards Arab/Middle Easterners and how this problem is complicated by the conflation of religion and ethnicity. In addition, I will present a study of Arab/Middle Eastern Americans’ perceptions of discrimination, with special attention to the issues of religious identification and acculturation.

The Navy amply provided LT Geeseman many opportunities to pursue his original interests and to also pursue research questions well beyond his academic training.
Do I laugh with the sinners or cry with the saints? Understanding obsessive religious fears and compulsive versus religious rituals.
March 3, 2016
Obsessive-Compulsive Disorder (OCD) is characterized by obsessions, which give rise to compulsions in an effort to reduce associated anxiety or perceived harmful effects. Scrupulosity is an OCD manifestation in which obsessive fears and compulsive rituals are religious or moral. Consequently, patients with scrupulosity often derive anxiety and distress from religion rather than comfort. Moreover, clinicians struggle with scrupulous patients whose pathology is entangled with their culturally normative values. In fact, scrupulosity is manifest differently as a function of specific cultural values and religious observances. Scrupulosity is also associated with poor insight and magical thinking. Not surprisingly, several studies demonstrate that the presence of religious obsessions predicts poor treatment response. In this talk, I will discuss the nature of scrupulosity with attention to religious and cognitive influences, the relationship between religion and OCD, obsessional meta-cognitive styles, concepts of God, beliefs about scrupulosity among clergy, and relevant psychiatric comorbidity.
Comparative Effectiveness of a culturally adapted Brief Motivational Intervention and non-adapted brief motivational intervention to reduce heavy drinking among Hispanic Males
March 11, 2015
This presentation will provide the background and rationale for evaluating the comparative effectiveness of a culturally adapted brief motivational intervention among heavy drinking Hispanic males. Research findings from the first randomized trial that was sufficiently powered to determine ethnic differences in drinking outcomes following brief motivational intervention in the medical setting will be presented. These results led to the current research funded by the Patient Centered Outcomes Research Institute to compare a culturally adapted and non-adapted brief motivational intervention among heavy drinking Hispanic males in a bilingual, bicultural context. The theoretical framework and specific aims for the currently funded research will be described. In addition, the process for developing the cultural adaptation using a community based participatory research approach will be described and recent results of qualitative research and their implication for the refinement of the cultural adaptation to be tested in a comparative effectiveness trial will be presented.

On the Dynamics of Thinking and Feeling
Wednesday April 2, 2014
The model developed in my laboratory links components of emotion (Arousal and Valence) to cognitive processes (Attention and Memory). Specifically, the model proposes that Arousal (shifts in autonomic activation) is related to shifts in attention. Increases in arousal orient our attentional systems towards signals from our external environment, while decreases orient our attention to our internal environment. Valence affects whether the activation pattern produced by the signal is strengthened (through repetition and rumination) or integrated (through elaboration and reflection) with other activation patterns. Further, it is suggested that shifts in attention act to amplify the signals from the specified source, either external or internal. Increases in arousal lead to amplification of attended signals from our external environment, while decreases amplify internal signals (we tend to focus on one or the other). An additional hypothesis stemming from the model is that emotional experiences can have different sources in their generation; emotions are attributable to an external source (seeing the spider produces a fear response) or an internal source, emotions in the absence of external stimuli (thinking about a spider can also produce fear). The model will be presented along with research testing various aspects of the model.

Integrating salivary bioscience into studies of children, youth, and Families
April 8th, 2013 2:00PM - 3:15 PM - UAC 275
Within the past three decades, discoveries that enabled the noninvasive measurement of the psychobiology of stress (in saliva) have added new dimensions to the study of health and human development. This widespread enthusiasm has led to somewhat of a renaissance in behavioral science. At the cutting edge, the focus is on testing innovative theoretical models of the effects of the social environment on behavior as a function of multilevel biosocial processes. Historically the focus has been on salivary cortisol and correlates of individual differences in the activity of the hypothalamic-pituitary-adrenal (HPA) axis. In the past 5 years, renewed interest in salivary alpha-amylase (sAA) -- a surrogate marker of the autonomic/sympathetic nervous system component of the psychobiology of stress-- has expanded this focus in important ways. Dr. Douglas A. Granger, Professor and Director of the Center for Interdisciplinary Salivary Bioscience Research at Johns Hopkins University, will speak about his research on salivary cortisol, sAA, and present for the first time new data on the correlates and concomitants of salivary nerve growth factor.
Integrating Salivary Bioscience into Developmental, Behavioral, and Health Sciences: Current prospects and future directions
April 8th, 2013 6:00 PM - 7:15 PM - Alkek 250
In the history of science, major advances are often made at the interface created by interdisciplinary integration. Advances in biotechnology, coupled with the recent characterization of a vast array of analytes and biomarkers in saliva, have created the opportunity to measure components of biological systems in oral fluids and apply knowledge gained from those measurements to a diverse spectrum of research. The implications are profound--from a single drop of saliva, information can be obtained about the psychobiology of stress, infectious disease history, environmental exposure to chemicals, oral health status, and genetic variability relevant to behavior, cognition, and health. Furthermore, saliva sample collection is typically quick, minimally invasive, cost-efficient, and requires only minimal training. Dr. Douglas A. Granger, Professor and Director of the Center for Interdisciplinary Salivary Bioscience Research at Johns Hopkins University, a pioneer of salivary bioscience, will present an overview of this emerging field and its implications for the public at 6 pm in Alkek 250 on the Texas State University Campus.

Biology Department University of Texas at San Antonio
Director of the EEG/ERP lab Research Imaging Institute, UTHSCSA
Nicole Wicha holds a PhD in Cognitive Science from the University of California at San Diego, where she received interdisciplinary training in behavioral, computational and brain imaging techniques for addressing questions in Cognitive Neuroscience. She is now an Assistant Professor in the Department of Biology at the University of Texas at San Antonio, and holds a cross appointment with the University of Texas Health Science Center through the Research Imaging Center, where she is the Technical Director of the ERP laboratory. Dr. Wicha's research focuses on understanding how the brain processes language in real time using both behavioral and brain-imaging techniques, in particular event-related brain potentials (ERPs), which is a non-invasive direct measure of electrical brain activity with excellent precision in the time domain. Currently a primary focus in her lab is in understanding the unique processing capabilities of the bilingual brain. Some of the questions include how the bilingual brain predicts and processes two languages simultaneously, such as when reading a sentence that contains language switches, the implicit effects that one language can have on the other during processing or conversely how bilinguals process one language without interference from the other. Her lab research also examines how language and other cognitive abilities, such as arithmetic, interact in real time.
