Filled/Non-Filled Pairs: An Empirical Challenge To The Integrated Information Theory Of Consciousness, Amber R. Hopkins, Kelvin J. Mcqueen Dec 2021

Filled/Non-Filled Pairs: An Empirical Challenge To The Integrated Information Theory Of Consciousness, Amber R. Hopkins, Kelvin J. Mcqueen

Philosophy Faculty Articles and Research

Perceptual filling-in for vision is the insertion of visual properties (e.g., color, contour, luminance, or motion) into one’s visual field, when those properties have no corresponding retinal input. This paper introduces and provides preliminary empirical support for filled/non-filled pairs, pairs of images that appear identical, yet differ by amount of filling-in. It is argued that such image pairs are important to the experimental testing of theories of consciousness. We review recent experimental research and conclude that filling-in involves brain activity with relatively high integrated information (Φ) compared to veridical visual perceptions. We then present filled/non-filled pairs as …


The Contribution Of Racism-Related Stress And Adversity To Disparities In Birth Outcomes: Evidence And Research Recommendations, Sabrina R. Liu, Laura M. Glynn Nov 2021

The Contribution Of Racism-Related Stress And Adversity To Disparities In Birth Outcomes: Evidence And Research Recommendations, Sabrina R. Liu, Laura M. Glynn

Psychology Faculty Articles and Research

Currently, racial and ethnic differences in adverse birth outcomes and infant mortality are some of the largest and most persistent health disparities in the United States. This narrative review article synthesizes existing literature to present a conceptual model of how racism-related stress and adversity are critical determinants of such disparities. We describe how historical and ongoing racism has created conditions wherein women of color are disproportionately exposed to chronic, multilayered stress and adversity and how the biological consequences of exposure to these stressors confers risk for adverse birth outcomes. Next, we identify important priorities and considerations for future research, including …

Characterizing Human Random-Sequence Generation In Competitive And Non-Competitive Environments Using Lempel-Ziv Complexity, Alice Wong, Garance Merholz, Uri Maoz Oct 2021

Characterizing Human Random-Sequence Generation In Competitive And Non-Competitive Environments Using Lempel-Ziv Complexity, Alice Wong, Garance Merholz, Uri Maoz

Psychology Faculty Articles and Research

The human ability for random-sequence generation (RSG) is limited but improves in a competitive game environment with feedback. However, it remains unclear how random people can be during games and whether RSG during games can improve when explicitly informing people that they must be as random as possible to win the game. Nor is it known whether any such improvement in RSG transfers outside the game environment. To investigate this, we designed a pre/post intervention paradigm around a Rock-Paper-Scissors game followed by a questionnaire. During the game, we manipulated participants’ level of awareness of the computer’s strategy; they were either …


Burnout In The Nursing Profession: Extant Knowledge And Future Directions For Research And Practice, Sara Labelle Oct 2021

Burnout In The Nursing Profession: Extant Knowledge And Future Directions For Research And Practice, Sara Labelle

Communication Faculty Articles and Research

Burnout is a psychological state resulting from prolonged psychological or emotional job stress, and is a culmination of three factors: emotional exhaustion, depersonalization, and reduced personal accomplishment. Due to the nature of the “people-work” they must constantly perform, along with a highly stressful and unpredictable work environment, nurses have alarmingly high rates of burnout among members of their profession. Given the importance of research on burnout to understanding the context-specific stressors and challenges of nursing, this review offers a synthesis of research published in the last decade in both nursing and communication journals, with an emphasis on discussing opportunities for …


Spatial Disparities: The Role Of Nativity In Neighborhood Exposure To Alcohol And Tobacco Retailers, Georgiana Bostean, Luis A. Sánchez, Jason A. Douglas Sep 2021

Spatial Disparities: The Role Of Nativity In Neighborhood Exposure To Alcohol And Tobacco Retailers, Georgiana Bostean, Luis A. Sánchez, Jason A. Douglas

Sociology Faculty Articles and Research

Studies of retail environment, one of the social determinants of health, document racial/ethnic disparities in exposure to alcohol and tobacco (A and T) retailers, but have largely overlooked nativity. We examined associations between A and T retailer density and rates of foreign-born Latinx and foreign-born Asian residents in California census tracts (N = 7888), using spatial regressions and controlling for population and ecological confounders (e.g., population density, zoning, residential instability, urbanicity). Socio-demographic data came from the American Community Survey (2012–2016); census tract density of A and T retailers came from geocoded addresses from state license data for off-sale alcohol distributors …

What Predicts How Safe People Feel In Their Neighborhoods And Does It Depend On Functional Status?, Alfredo J. Velasquez, Jason A. Douglas, Fangqi Guo, Jennifer W. Robinette

Health Sciences and Kinesiology Faculty Articles

Feeling unsafe in one's neighborhood is related to poor health. Features of the neighborhood environment have been suggested to inform perceptions of neighborhood safety. Yet, the relative contribution of these features (e.g., uneven sidewalks, crime, perceived neighborhood physical disorder) on perceived neighborhood safety, particularly among people with disabilities who may view themselves as more vulnerable, is not well understood. We examined whether sidewalk quality assessed by third party raters, county-level crime rates, and perceived neighborhood disorder would relate to neighborhood safety concerns, and whether functional limitations would exacerbate these links. Using data from the 2012/2014 waves of the Health and …

Burstiness And Stochasticity In The Malleability Of Physical Activity, Vincent Berardi, David Pincus, Evan Walker, Marc A. Adams Sep 2021

Burstiness And Stochasticity In The Malleability Of Physical Activity, Vincent Berardi, David Pincus, Evan Walker, Marc A. Adams

Psychology Faculty Articles and Research

This study examined whether patterns of self-organization in physical activity (PA) predicted long-term success in a yearlong PA intervention. Increased moderate to vigorous PA (MVPA) was targeted in insufficiently active adults (N = 512) via goal setting and financial reinforcement. The degree to which inverse power law distributions, which are reflective of self-organization, summarized (a) daily MVPA and (b) time elapsed between meeting daily goals (goal attainment interresponse times) was calculated. Goal attainment interresponse times were also used to calculate burstiness, the degree to which meeting daily goals clustered in time. Inverse power laws accurately summarized interresponse times, but …

Applying Theoretical Models Of Positive Emotion To Improve Pediatric Asthma: A Positive Psychology Approach, Brooke N. Jenkins, Judith T. Moskowitz, Jill Halterman, Zeev N. Kain Aug 2021

Applying Theoretical Models Of Positive Emotion To Improve Pediatric Asthma: A Positive Psychology Approach, Brooke N. Jenkins, Judith T. Moskowitz, Jill Halterman, Zeev N. Kain

Psychology Faculty Articles and Research

Positive emotion, encompassing feelings such as joy and happiness, has been shown to predict a multitude of health outcomes. However, the role of positive emotion in pediatric asthma is not understood. No work to date has examined how positive emotion may offer benefits to children and adolescents with asthma. Based on theory and models of positive emotion and health, we hypothesize that positive emotion may improve asthma outcomes through mediators such as health behaviors and health-relevant physiological functioning. Moreover, boosting positive emotion during times of stress may be particularly relevant in mitigating asthma symptoms. In the present commentary, we elaborate …

County-Level Factors That Influenced The Trajectory Of Covid-19 Incidence In The New York City Area, Ashley Wendell Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

More than a century of research has shown that sociodemographic conditions affect infectious disease transmission. In the late spring and early summer of 2020, reports of the effects of sociodemographic variables on the spread of COVID- 19 were used in the media with minimal scientific proof attached. With new cases of COVID-19 surging in the United States at that time, it became essential to better understand how the spread of COVID-19 was varying across all segments of the population. We used hierarchical exponential growth curve modeling techniques to examine whether community socioeconomic characteristics uniquely influence the incidence of reported COVID-19 …


Sex As A Moderator In The Relationship Between Post-Operative Pain And Analgesics Administered In Children Undergoing Elective Surgery, Amber M. Osorno, Michelle A. Fortier, Zeev N. Kain, Brooke N. Jenkins May 2021

Sex As A Moderator In The Relationship Between Post-Operative Pain And Analgesics Administered In Children Undergoing Elective Surgery, Amber M. Osorno, Michelle A. Fortier, Zeev N. Kain, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

About 85% of children who undergo elective surgery experience pain post-operatively and many do not receive proper pain management care after discharge. Most parents lack an understanding of proper pain care management using analgesics upon discharge. Research reveals that adults rate girls as more sensitive to pain and that they display a greater amount of pain in a pediatric post-operative environment. In adulthood, women report more sensations of pain and have a higher pain tolerance, which can be attributed to physiological characteristics. Nonetheless, the social differences by which boys and girls experience pain and express their pain cannot be denied. …


The Relationship Between Perceived Neighborhood Disorder And Type 2 Diabetes Risk Across Different Racial/Ethnic Groups, Min Yu, Jennifer N. Robinette May 2021

The Relationship Between Perceived Neighborhood Disorder And Type 2 Diabetes Risk Across Different Racial/Ethnic Groups, Min Yu, Jennifer N. Robinette

Student Scholar Symposium Abstracts and Posters

Approximately 32 million Americans have Type 2 Diabetes and that number is growing rapidly. Type 2 Diabetes is sensitive to environmental factors, and higher prevalence rates are often observed in disordered neighborhoods (i.e., those with more trash and vandalism). Through discriminatory practices such as redlining, racially restrictive covenants, urban renewal, and gentrification, marginalized racial/ethnic groups are more likely to live in disordered neighborhoods compared to non-Hispanic Whites. These disparities may also contribute to similar disparities in Type 2 Diabetes rates. Yet, research indicates that there may be racial/ethnic differences in the interpretation of neighborhood disorder as a threat to health …


Vaccine Hesitancy, The Covid 19 Pandemic, And Christian Fundamentalism, Nicole Drew May 2021

Vaccine Hesitancy, The Covid 19 Pandemic, And Christian Fundamentalism, Nicole Drew

Student Scholar Symposium Abstracts and Posters

Over the past few decades, religion has continued to move to the forefront of American politics, with many viewing fundamental Christianity as synonymous with the Republican Party. Donald Trump's presidency has increased this tenfold, with significant figures within American Christianity voicing their support for him and tying him into Biblical prophecies. In the media, this appears to have affected how this demographic views the COVID 19 pandemic. The literature in this area focuses heavily on American Christians' response to mask mandates, stay-at-home orders, and other attempts to mitigate the spread of the CoronaVirus; however, research on how this same demographic …

A total of 2,092 participants (ages 20–59; 48.8% female) had accelerometer-measured sedentary behavior, light physical activity, and moderate-to-vigorous physical activity. Participants were classified as light, moderate, frequent, or non-current cannabis users depending on how often they used …


What Is The Readiness Potential?, Aaron Schurger, Pengbo 'Ben' Hu, Joanna Pak, Adina L. Roskies Apr 2021

What Is The Readiness Potential?, Aaron Schurger, Pengbo 'Ben' Hu, Joanna Pak, Adina L. Roskies

Psychology Faculty Articles and Research

The readiness potential (RP) has been widely interpreted to indicate preparation for movement and is used to argue that our brains decide before we do. It thus has been a fulcrum for discussion about the neuroscience of free will.

Recent computational models provide an alternative framework for thinking about the significance of the RP, suggesting instead that the RP is a natural result of the operation of a stochastic accumulator process of decision-making, analyzed by time-locking to threshold-crossing events.

These models call for a reevaluation of: (i) the ontological standing of the RP as reflecting a real, causally efficacious signal …


Effects Of News And Threat Perceptions On Americans’ Covid-19 Precautionary Behaviors, Riva Tukachinsky Forster, Megan A. Vendemia Apr 2021

Effects Of News And Threat Perceptions On Americans’ Covid-19 Precautionary Behaviors, Riva Tukachinsky Forster, Megan A. Vendemia

Communication Faculty Articles and Research

Our study examines the relationship between news exposure at the onset of the COVID-19 pandemic, personal threat beliefs, beliefs about others’ threat perceptions, and participation in precautionary actions. A survey of 377 U.S . adults revealed a significant main effect of news exposure on various precautionary behaviors (e.g., facial mask wear, physical distancing). Personal threat beliefs and beliefs about others’ threat perceptions serve as unique mechanisms mediating the effect of news on specific CDC-recommended and less socially desirable actions. These findings can guide news sources covering health crises in a socially responsible manner.


Positive Psychological Well‐Being And Cardiovascular Disease: Exploring Mechanistic And Developmental Pathways, Julia K. Boehm Apr 2021

Positive Psychological Well‐Being And Cardiovascular Disease: Exploring Mechanistic And Developmental Pathways, Julia K. Boehm

Psychology Faculty Articles and Research

Empirical research regarding the health benefits of positive psychological well‐being (e.g., positive emotions, life satisfaction, purpose in life, and optimism) has flourished in recent years, particularly with regard to cardiovascular disease. This paper reviews the state of evidence for well‐being's association with cardiovascular disease in both healthy individuals and those diagnosed with a disease. Prospective studies consistently indicate well‐being reduces cardiovascular events in healthy and, to a lesser extent, patient populations. Potential pathways that link well‐being with cardiovascular disease are discussed (including health behaviors, physiological processes, and stress buffering), although the existing evidence is mostly cross‐sectional which limits conclusions about …
