Adopting Identities: Associations Between Adoption, Racial-Ethnic, And Sexual Minority Parent Socialization And Children’S Attachment, Global Self-Worth, And Understanding Of Identity, Kyle A. Simon Jan 2018

Adopting Identities: Associations Between Adoption, Racial-Ethnic, And Sexual Minority Parent Socialization And Children’S Attachment, Global Self-Worth, And Understanding Of Identity, Kyle A. Simon

Theses and Dissertations--Psychology

Utilizing a sample of lesbian, gay, and heterosexual adoptive parent families with school-age children, results suggested that parents engage in adoption communication less but racial-ethnic socialization more when a child is transracially adopted. No differences were found in lesbian and gay parents socialization practices for adoptive or racial-ethnic identity. Further, lesbian and gay parents engaged in sexual minority parent socialization less than adoptive or racial-ethnic socialization. Children’s self-worth was related to sex but not socialization practices such that girls reported lower self-worth, and no significant associations were present for children’s closeness. Children’s age, sex, and transracial adoptive status were predictive …


The Role Of Couple Sleep Concordance In Subjective Sleep Quality: Attachment As A Moderator Of Associations, Taylor L. Elsey Jan 2018

The Role Of Couple Sleep Concordance In Subjective Sleep Quality: Attachment As A Moderator Of Associations, Taylor L. Elsey

Theses and Dissertations--Psychology

Sleep is not a solitary activity for the majority of adults, this impacts sleep quality, health, and well-being. Couples experience sleep concordance, or a synchronization of sleep-wake times, which can improve and diminish sleep quality (Gunn et al., 2015). This study explores the association between sleep concordance and sleep quality by examining attachment style as a moderator. Daily sleep diaries were completed by 179 heterosexual couples. Sleep concordance was calculated by dividing total time partners were in bed together by total time at least one partner was in bed each day. Data were analyzed using a multilevel model described by …


Exploring Illusions Of Height In Suit Design, Michael P. Lee Jan 2018

Exploring Illusions Of Height In Suit Design, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to explore how the design of clothing, specifically the design of the suit, can create height illusions.

Background: Taller people enjoy many advantages, such as increased income and perceived attractiveness. These advantages motivate people to try to appear taller than they actually are, and clothing experts provide advice on how to accomplish this. However, there is little empirical evidence to validate the illusory effects clothing might have on overall height perception. The few studies that have explored illusions of body size created by clothing design have been limited in two important ways – …


Characterizing The Role Of Glucocorticoids In The Sign Tracking Behavior Of Male Japanese Quail (Coturnix Japonica), Beth A. Rice Jan 2018

Characterizing The Role Of Glucocorticoids In The Sign Tracking Behavior Of Male Japanese Quail (Coturnix Japonica), Beth A. Rice

Theses and Dissertations--Psychology

A devastating feature of drug-dependence is the susceptibility of relapse (40-60%) after stretches of abstinence. One theory that may account for relapse suggests that drug cues (e.g., paraphernalia) may increase stress hormones, and this may prompt relapse. Repeatedly pairing a neutral cue with a reward is commonly utilized to measure what subjects learn about a cue that is predictive of reward. Research has shown that animals that attend to a cue more than to the reward (sign trackers) may be more vulnerable to drug addiction. Additionally, research has shown that sign tracking is associated with an increase in corticosterone (CORT), …


Looking The Part: An Examination Of Longitudinal Gender Presentation Among Children With Gay, Lesbian, And Heterosexual Adoptive Parents, Samuel T. Bruun Jan 2018

Looking The Part: An Examination Of Longitudinal Gender Presentation Among Children With Gay, Lesbian, And Heterosexual Adoptive Parents, Samuel T. Bruun

Theses and Dissertations--Psychology

Gender presentation, appearing in a way that fits social expectations of one’s gender role, represents one of the most obvious ways in which one’s gender identity becomes salient to others. This quality is especially relevant to note given the continued controversy surrounding children’s gender role development when raised by non-heterosexual parents. The current study is an examination of how gender presentation develops in adopted children with lesbian, gay, and heterosexual parents across two time points (Wave 1: N = 106, Mage = 36.07 months; Wave 2: N = 90, Mage = 8.34). Children’s gender presentation was analyzed using …


Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews Jan 2018

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …


The Self-Reported And Behavioral Effects Of Propylene Glycol And Vegetable Glycerin In Electronic Cigarette Liquids, Arit M. Harvanko Jan 2018

The Self-Reported And Behavioral Effects Of Propylene Glycol And Vegetable Glycerin In Electronic Cigarette Liquids, Arit M. Harvanko

Theses and Dissertations--Psychology

Little is known about how electronic cigarette (EC) users manipulate device parameters, what factors drive their use, and how non-nicotine ingredients influence the stimulus effects of EC aerosols. The ingredients propylene glycol (PG) or vegetable glycerin (VG) serve as the base for virtually all electronic cigarette liquids, and information on how they affect the using experience would provide important groundwork for the study of other ingredients. In this dissertation, results from a survey and laboratory study focused on the stimulus effects of ECs, and the influence of PG and VG, will be discussed. A total of 522 regular EC users …


A Place Among The Stars? The Influence Of Religion And Creationism On Attitudes Towards Space Exploration And Beliefs In Extraterrestrial Life, Sarah R. Schiavone Jan 2018

A Place Among The Stars? The Influence Of Religion And Creationism On Attitudes Towards Space Exploration And Beliefs In Extraterrestrial Life, Sarah R. Schiavone

Theses and Dissertations--Psychology

Space exploration continues to expand humanity’s understanding of the universe. And, while Americans have widely favorable attitudes towards efforts to explore outer space, certain religious beliefs appear to be associated with more negative attitudes towards space exploration and the search for extraterrestrial life. The current study explored the role of religion and creationism on attitudes towards space exploration and the search for extraterrestrial life. Priming techniques were used to test whether increasing the accessibility of religious and creationist concepts led to more negative attitudes towards space exploration and beliefs about extraterrestrial life. Participants (N = 230) encountered an explicit …


Discovery Of Natural Product Analogs Against Ethanol-Induced Cytotoxicity In Hippocampal Slice Cultures, Meredith A. Saunders-Mattingly Jan 2018

Discovery Of Natural Product Analogs Against Ethanol-Induced Cytotoxicity In Hippocampal Slice Cultures, Meredith A. Saunders-Mattingly

Theses and Dissertations--Psychology

An estimated 13.9% of Americans currently meet criteria for an alcohol (ethanol; EtOH) use disorder (AUD). While there are 4 medications approved by the Food and Drug Administration (FDA) to treat AUD, these treatments have demonstrated poor clinical efficacy. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about the mechanisms underlying EtOH-induced changes in neurobiology and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for AUD in a rodent organotypic hippocampal slice culture model. Initial screens of several natural product compounds identified …


Bipolarity And The Five Factor Model Of Personality Disorder, Cristina Crego Jan 2018

Bipolarity And The Five Factor Model Of Personality Disorder, Cristina Crego

Theses and Dissertations--Psychology

The predominant model of general personality structure is arguably the Five Factor Model (FFM), consisting of the five broad domains of neuroticism, extraversion, openness, agreeableness, and conscientiousness. The FFM of personality disorder (FFMPD) has proposed maladaptive variants at both poles of the FFM. The purpose of the current study was to identify a subset of FFMPD scales, utilizing factor analysis, that illustrate, and provide a potential measure of, the bipolarity present in the FFMPD. All of the FFMPD scales were administered to 443 community participants recruited from Amazon Mechanical Turk. Bipolarity was evident in a series of factor analyses of …


Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke Jan 2018

Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke

Theses and Dissertations--Psychology

Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, traffic tickets, and contribute to an estimated 120 million occurrences of impaired driving per year (Evans, 2004; Jewett et al., 2015). Survey research on DUI offenders indicates traits of impulsivity (e.g., sensation seeking). Together, these pieces of evidence suggest that DUI offenders display patterns of impulsive action and risk-taking while driving. However, to-date DUI offenders are rarely studied in a laboratory setting, and not much is known about how they respond to a dose of alcohol. The present study examined the …


Effects Of Social Interaction On Morphine Conditioned Place Preference In Adolescent Male Rats, Virginia G. Weiss Jan 2018

Effects Of Social Interaction On Morphine Conditioned Place Preference In Adolescent Male Rats, Virginia G. Weiss

Theses and Dissertations--Psychology

The fact that adolescents commonly initiate drug use in social settings is well established. Both clinical and preclinical research has investigated how social interaction is altered by a variety of drugs of abuse. What is less understood is how the rewarding value of drugs of abuse is affected by the presence of social peers. This dissertation aimed to investigate the interaction of morphine and social play on conditioned place preference (CPP) in adolescent male Sprague Dawley rats, using both behavioral and immunohistochemistry (IHC) methods. Rats were exposed to morphine (0, 1, or 3 mg/kg; s.c.), social interaction, or a combination …


Person-Centered Analysis Of Adhd Comorbidities And Differential Characteristics And Outcomes, Christine Anne Lee Jan 2018

Person-Centered Analysis Of Adhd Comorbidities And Differential Characteristics And Outcomes, Christine Anne Lee

Theses and Dissertations--Psychology

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent and impairing childhood disorders (5%; American Psychiatric Association, 2013), yet it is often studied in isolation. Such an approach is at odds with the clinical reality, where ADHD has a high comorbidity with oppositional defiant disorder, anxiety, and depression (Jensen, Martin, & Cantwell, 1997). Based on the possible presentations of ADHD with both externalizing and internalizing symptoms, there may be differences in associated characteristics, areas of impairment, and resulting assessment interventions. Therefore, the present study investigated how ADHD comorbidities manifested in a population of 233 elementary age children and how these …


Potential Candidates For Treating Deficits Associated With Developmental Ethanol Exposure In A Rodent Model: Solidago Nemoralis & Dimethoxybenzylidene-Anabasine, Logan James Fields Jan 2018

Potential Candidates For Treating Deficits Associated With Developmental Ethanol Exposure In A Rodent Model: Solidago Nemoralis & Dimethoxybenzylidene-Anabasine, Logan James Fields

Theses and Dissertations--Psychology

Prenatal alcohol exposure (Fetal Alcohol Syndrome [FAS] and Fetal Alcohol Spectrum Disorders [FASD’s]) represents the leading preventable cause of intellectual disabilities in the western world, with FASDs estimated to affect approximately 2-5% of live births in the United States at an approximate annual cost of $3.6 billion (CDC, 2015; May et al., 2009). Ethanol (ETOH) exposure during development can lead to a variety of long-term behavioral impairments including problems with executive functioning, motor coordination, spatial learning, attention, and hyperactivity (Jones, 2011; Mattson & Riley, 1998). Much research has been conducted to develop pharmacological and/or environmental interventions to reduce these deficits, …


Mmpi-2-Rf Underreporting Validity Scales In Firefighter Applicants: A Cross-Validation Study, Kullen Charles Balthrop Jan 2018

Mmpi-2-Rf Underreporting Validity Scales In Firefighter Applicants: A Cross-Validation Study, Kullen Charles Balthrop

Theses and Dissertations--Psychology

The identification of potential underreporting in employment evaluations is important to consider when examining a measure’s validity. This importance increases in personnel selection involving high-virtue positions (e.g., police officers and firefighters). The current study aimed to utilize an archival firefighter applicant sample to examine the construct validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form’s (MMPI-2-RF) underreporting scales (L-r and K-r). Results were analyzed using a correlation matrix comprised of a modified version of the Multi-Trait Multi-Method Matrix (MTMM), as well as multiple regression and partial correlation. The present study provides additional support for the construct validity of the MMPI-2-RF’s underreporting …


Gender-Based Harassment In Early Adolescence: Group And Individual Predictors Of Perpetration, Michelle Jennine Tam Jan 2018

Gender-Based Harassment In Early Adolescence: Group And Individual Predictors Of Perpetration, Michelle Jennine Tam

Theses and Dissertations--Psychology

The current study examined gender-based harassment in early adolescence and the characteristics of individuals who perpetrate such harassment (specifically, experiences with witnessing gender-based harassment and gender identity). Students in seventh and eighth grade (n = 483; 247 girls, 236 boys) completed surveys containing measures of gender identity (perceived same and other-gender typicality, felt pressure to conform to gender norms, and gender contentedness), and questions about witnessing and perpetrating teasing, bullying, and rejection because of a peer’s gender typicality or atypicality. Results revealed that the more GBH an individual had previously witnessed in their classroom, the more likely they were …


Causal Attributions And Smoking Behaviors In Cervical Cancer Survivors: A Mixed-Methods Pilot Study, Gabriella E. Puleo Jan 2018

Causal Attributions And Smoking Behaviors In Cervical Cancer Survivors: A Mixed-Methods Pilot Study, Gabriella E. Puleo

Theses and Dissertations--Psychology

This cross-sectional, mixed-methods study examined the nature of, and association between, causal attributions and current smoking behavior in cervical cancer survivors who were smokers at cancer diagnosis (n=50). As a whole, participants’ beliefs about smoking as a risk factor or cause of cervical cancer in general (i.e., global attribution) and/or their own cervical cancer (i.e., personal attribution) reflected far greater endorsement of global than personal attributions. Data collection involved a quantitative survey and an optional semi-structured interview to assess key variables (i.e., smoking behavior and causal attributions). Data were analyzed via descriptive statistics and inferential tests, all of …

Gender, Sexuality, And Categories Of Risk: Physician Views Of Cervical Cancer In Bangalore, India, Emily G. Capilouto

Theses and Dissertations--Anthropology

India has one of the highest rates of cervical cancer morbidity and mortality globally. Despite this, there are no national or state-wide screening efforts for cervical cancer and its prevention in India. In an effort to understand the magnitude of cervical cancer in Bangalore, India, this research draws upon data collected in hospital contexts over a month-long period to explore the ways in which physician attitudes contribute to understandings of cervical cancer and its prevention in the growing urban context of Bangalore.


Variation Of Native American Ceramics In The Big Bend Region Of The Lower Ocmulgee River Valley, Georgia, Ad 1540 To Ad 1715, Rachel Paige Hensler Jan 2018

Variation Of Native American Ceramics In The Big Bend Region Of The Lower Ocmulgee River Valley, Georgia, Ad 1540 To Ad 1715, Rachel Paige Hensler

Theses and Dissertations--Anthropology

Studies of European colonialism in the Western Hemisphere have shifted focus from areas of direct European/Native American contact, to investigate Native American groups outside of direct European contact. During Spanish colonization of the Southeastern United States (AD 1520 to AD 1715), the Big Bend region of the Ocmulgee River Valley, in Georgia, located about 160 kilometers from Spanish occupied coast, was inhabited by a Native American polity from the Late Prehistoric into the Mission period. This location is ideal for studying indirect contact.

Changes in ceramic production can be used to identify changes in Native American interaction through time. Attributes …


“We’Re Being Left To Blight”: Green Urban Development And Racialized Space In Kansas City, Chhaya Kolavalli Jan 2018

“We’Re Being Left To Blight”: Green Urban Development And Racialized Space In Kansas City, Chhaya Kolavalli

Theses and Dissertations--Anthropology

In this dissertation, I explore ‘green’ urban development and urban agriculture projects from the perspective of residents of an African American majority neighborhood in Kansas City—who reside in an area referred to as a ‘blighted food desert’ by local policy makers. In Kansas City, extensive city government support exists for urban agricultural projects, which are touted not just as a solution to poverty associated issues such food insecurity and obesity, but also as a remedy for ‘blight,’ violence and crime, and vacant urban land. Specific narratives of Kansas City’s past are used to prop up and legitimate these future visions …


Binational Farming Families Of Southern Appalachia And The Mexican Bajio, Mary Elizabeth W. Schmid Jan 2018

Binational Farming Families Of Southern Appalachia And The Mexican Bajio, Mary Elizabeth W. Schmid

Theses and Dissertations--Anthropology

Over the last four decades, farming families throughout North America experienced significant transitions due, in part, to the implementation of the North American Free Trade Agreement. This multi-sited dissertation investigates the ways in which a network of binational (Mexican-American) families organize their small- to mid-scale farming enterprises, engage in global networks as food producers, and contribute to rural economies in the southeastern U.S. and the Mexican Bajío. To mitigate difficult transitions that came with the globalizing of agri-food markets, members of this extended family group created collaborative, kin-based arrangements to produce, distribute, and market fresh-market fruits and vegetables in the …


Precarity In Paradise: Tourism, Migration, And The Broader Causes Of Instability In Roatán, Honduras, Heather Jan Sawyer Jan 2018

Precarity In Paradise: Tourism, Migration, And The Broader Causes Of Instability In Roatán, Honduras, Heather Jan Sawyer

Theses and Dissertations--Anthropology

Since the 1990s, the population on the Honduran island of Roatán has grown from around 20,000 (mostly English-speaking Islanders) to roughly 100,000 residents (at least half of which are native Spanish-speaking Ladinos from the Honduran mainland) (Bay Islands Voice 2014b). This population growth has occurred alongside increasing forms of economic and environmental precarity that have fueled widespread instability on the island. While ethnic tensions between Ladinos and Islanders have existed since colonial times, conflict between the groups reached a crescendo in 2014 after the murder of a cruise ship employee in Roatán by a Ladino migrant. This sparked a …


Late Pleistocene Adaptations In The Midsouth: The Paleoindian Occupation Of The Carson-Conn-Short Site And The Lower Tennessee River Valley, James Scott Jones Jan 2018

Late Pleistocene Adaptations In The Midsouth: The Paleoindian Occupation Of The Carson-Conn-Short Site And The Lower Tennessee River Valley, James Scott Jones

Theses and Dissertations--Anthropology

The Midsouth has long been known to be a locus of Paleoindian (13,200-10,000 yrs B.P.) populations. Paleoindian populations have generally been characterized as highly mobile hunter-gatherers with egalitarian social structure. Utilizing the theoretical lens of diversification and intensification of resource use, the Late Pleistocene adaptations of the region’s populations are examined from both a large scale or coarse grain perspective as well as more fine grain data from the site level. Previous models of Paleoindian adaptations are defined and tested in this study to determine the applicability of these models with new data. Coarse grain data are derived from lithic …


Hyperhomocysteinemia-Induced Gene Expression Changes In The Cell Types Of The Brain, Erica M. Weekman, Abigail E. Woolums, Tiffany L. Sudduth, Donna M. Wilcock Dec 2017

Hyperhomocysteinemia-Induced Gene Expression Changes In The Cell Types Of The Brain, Erica M. Weekman, Abigail E. Woolums, Tiffany L. Sudduth, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

High plasma levels of homocysteine, termed hyperhomocysteinemia, are a risk factor for vascular cognitive impairment and dementia, which is the second leading cause of dementia. While hyperhomocysteinemia induces microhemorrhages and cognitive decline in mice, the specific effect of hyperhomocysteinemia on each cell type remains unknown. We took separate cultures of astrocytes, microglia, endothelial cells, and neuronal cells and treated each with moderate levels of homocysteine for 24, 48, 72, and 96 hr. We then determined the gene expression changes for cell-specific markers and neuroinflammatory markers including the matrix metalloproteinase 9 system. Astrocytes had decreased levels of several astrocytic end feet …


Medicaid Managed Care And The Health Care Utilization Of Foster Children, Makayla Palmer, James Marton, Aaron Yelowitz, Jeffery Talbert Dec 2017

Medicaid Managed Care And The Health Care Utilization Of Foster Children, Makayla Palmer, James Marton, Aaron Yelowitz, Jeffery Talbert

Economics Faculty Publications

A recent trend in state Medicaid programs is the transition of vulnerable populations into Medicaid managed care (MMC) who were initially carved out of such coverage, such as foster children or those with disabilities. The purpose of this article is to evaluate the impact of the transition of foster children from fee-for-service Medicaid coverage to MMC coverage on outpatient health care utilization. There is very little empirical evidence on the impact of managed care on the health care utilization of foster children because of the recent timing of these transitions as well as challenges associated with finding data sets large …


Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall Dec 2017

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Background

Previous research on Uganda's poststroke population revealed that their level of dietary salt knowledge did not lead to healthier consumption choices.

Purpose

Identify barriers and motivators for healthy dietary behaviors and evaluate the understanding of widely accepted salt regulation mechanisms among poststroke patients in Uganda.

Methods

Convergent parallel mixed methods triangulation design comprised a cross-sectional survey (n = 81) and 8 focus group discussions with 7-10 poststroke participants in each group. We assessed participant characteristics and obtained insights into their salt consumption attitudes, perceptions, and knowledge. Qualitative responses were analyzed using an inductive approach with thematic analytic procedures. Relationships …


Cerebrovascular Pathology In Down Syndrome And Alzheimer Disease, Elizabeth Head, Michael J. Phelan, Eric Doran, Ronald C. Kim, Wayne W. Poon, Frederick A. Schmitt, Ira T. Lott Dec 2017

Cerebrovascular Pathology In Down Syndrome And Alzheimer Disease, Elizabeth Head, Michael J. Phelan, Eric Doran, Ronald C. Kim, Wayne W. Poon, Frederick A. Schmitt, Ira T. Lott

Sanders-Brown Center on Aging Faculty Publications

People with Down syndrome (DS) are at high risk for developing Alzheimer disease (AD) with age. Typically, by age 40 years, most people with DS have sufficient neuropathology for an AD diagnosis. Interestingly, atherosclerosis and hypertension are atypical in DS with age, suggesting the lack of these vascular risk factors may be associated with reduced cerebrovascular pathology. However, because the extra copy of APP leads to increased beta-amyloid peptide (Aβ) accumulation in DS, we hypothesized that there would be more extensive and widespread cerebral amyloid angiopathy (CAA) with age in DS relative to sporadic AD. To test this hypothesis CAA, …


Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore Dec 2017

Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore

Psychology Faculty Publications

Attentional bias to alcohol-related stimuli is believed to be an important contributor to the development and maintenance of drug abuse. There is a considerable body of research examining attentional bias, much of which has typically utilized image-display tasks as a means to assess the phenomenon. Little, however, is known about the nature of this bias in an individual’s natural environment. The current study sought to implement a novel approach to assessing attentional bias in vivo. Participants wore portable eye-tracking glasses that recorded video from their point of view and measured fixation time to objects they observed. They entered a room …
