Research Methods In Psychology: A Feminist Exercise To Facilitate Students’ Understanding Of Operational Definitions, Observation, And Inter-Rater Reliability, Amy C. Moors Jan 2020

Research Methods In Psychology: A Feminist Exercise To Facilitate Students’ Understanding Of Operational Definitions, Observation, And Inter-Rater Reliability, Amy C. Moors

Psychology Faculty Articles and Research

"As an illustrative example of how I use a feminist-centered approach to teach core research methods concepts, below, I outline the aims and details of how to replicate one of my students’ favorite activities. This activity ties together concepts of operational definitions, observation, and inter-rater reliability through coding of “creepy” behaviors in a Saturday Night Live short video produced by The Lonely Island, featuring Nicki Minaj and John Waters (2011; see https://www.youtube.com/watch?v=tLPZmPaHme0). In the first part of the exercise, students are instructed to code observations of creepy behaviors without an operational definition. In the second part, students …

Testing The Tripartite Influence Model Among Heterosexual, Bisexual, And Lesbian Women, Vivienne M. Hazzard, Lauren M. Schaefer, Katherine Schaumberg, Anna M. Bardone-Cone, David A. Frederick, Kelly L. Klump, Drew A. Anderson, J. Kevin Thompson

Psychology Faculty Articles and Research

This cross-sectional study explored similarities and differences between heterosexual, bisexual, and lesbian women in levels of, and relationships between, the following constructs using a Tripartite Influence Model framework: family, peer, and media appearance pressures, thin- and muscular-ideal internalization, and eating disorder (ED) pathology. Self-identified heterosexual (n = 1,528), bisexual (n = 89), and lesbian (n = 278) undergraduate women completed the Sociocultural Attitudes Towards Appearance Questionnaire-4 and the Eating Disorder Examination-Questionnaire. Sexual orientation differences in appearance pressures, appearance-ideal internalization, and ED pathology were examined via analysis of variance tests. Relationships between these variables were examined with multi-group …


Identifying Depression In The National Health And Nutrition Examination Survey Data Using A Deep Learning Algorithm, Jihoon Oh, Kyongsik Yun, Uri Maoz, Tae-Suk Kim, Jeong-Ho Chae Jul 2019

Identifying Depression In The National Health And Nutrition Examination Survey Data Using A Deep Learning Algorithm, Jihoon Oh, Kyongsik Yun, Uri Maoz, Tae-Suk Kim, Jeong-Ho Chae

Psychology Faculty Articles and Research

Background

As depression is the leading cause of disability worldwide, large-scale surveys have been conducted to establish the occurrence and risk factors of depression. However, accurately estimating epidemiological factors leading up to depression has remained challenging. Deep-learning algorithms can be applied to assess the factors leading up to prevalence and clinical manifestations of depression.

Methods

Customized deep-neural-network and machine-learning classifiers were assessed using survey data from 19,725 participants from the NHANES database (from 1999 through 2014) and 4949 from the South Korea NHANES (K-NHANES) database in 2014.

Results

A deep-learning algorithm showed area under the receiver operating characteristic curve (AUCs) …


Sexuality Through The Lens Of Secure Base Attachment Dynamics: Individual Differences In Sexploration, Dylan Selterman, Amanda N. Gesselman, Amy C. Moors May 2019

Sexuality Through The Lens Of Secure Base Attachment Dynamics: Individual Differences In Sexploration, Dylan Selterman, Amanda N. Gesselman, Amy C. Moors

Psychology Faculty Articles and Research

A key aspect of attachment functioning is the secure base, which empowers people to explore their environments, though some individuals do this more effectively than others. While most researchers have focused on adult attachment dynamics in terms of stress and threat (safe haven), we argue that concerted attention should also focus on relational processes in times of optimal functioning. In this paper, we introduce a new theoretical concept: secure base sexual exploration (or sexploration). We define this as the degree to which individuals are able to effectively explore multifaceted dimensions of sexuality (e.g., behaviors, identity) as a function …


Multiple Loves: The Effects Of Attachment With Multiple Concurrent Romantic Partners On Relational Functioning, Amy C. Moors, William Ryan, William J. Chopik May 2019

Multiple Loves: The Effects Of Attachment With Multiple Concurrent Romantic Partners On Relational Functioning, Amy C. Moors, William Ryan, William J. Chopik

Psychology Faculty Articles and Research

In the present study, we sought to understand whether people in polyamorous relationships have similar attachment orientations with each of their partners. Further, we examined the extent to which the attachment relationship with a given partner affects relationship quality both within that relationship and across concurrent romantic relationships. We recruited a community sample of 357 people engaged in polyamory with at least two concurrent romantic partners. People engaged in polyamory exhibited secure attachment with both of their partners (low in avoidance and anxiety); specifically, these scores were lower than established norms. In terms of within-relationship effects, avoidance and anxiety with …


Development Of The State Optimism Measure, Rachel A. Millstein, Wei-Jean Chung, Bettina B. Hoeppner, Julia K. Boehm, Sean R. Legler, Carol A. Mastromauro, Jeff C. Huffman Apr 2019

Development Of The State Optimism Measure, Rachel A. Millstein, Wei-Jean Chung, Bettina B. Hoeppner, Julia K. Boehm, Sean R. Legler, Carol A. Mastromauro, Jeff C. Huffman

Psychology Faculty Articles and Research

Background

Optimism, or positive expectations about the future, is associated with better health. It is commonly assessed as a trait, but it may change over time and circumstance. Accordingly, we developed a measure of state optimism.

Methods

An initial 29-item pool was generated based on literature reviews and expert consultations. It was administered to three samples: sample 1 was a general healthy population (n = 136), sample 2 was people with cardiac disease (n = 96), and sample 3 was persons recovering from problematic substance use (n = 265). Exploratory factor analysis and item-level descriptive statistics were used to select …

Positive Affect And Health: What Do We Know And Where Next Should We Go?, Sarah D. Pressman, Brooke N. Jenkins, Judith T. Moskowitz

Psychology Faculty Articles and Research

Positive affect (PA) is associated with better health across a wide range of physical health outcomes. This review reflects on why the study of PA is an essential component of our understanding of physical health and expands on pathways that connect these two variables. To encourage forward movement in this burgeoning research area, measurement and design issues in the study of PA and health are discussed, as are the connections between PA and a range of different health outcomes. Plausible biological, social, and behavioral pathways that allow for positive feelings to get under the skin and influence physical wellness are …

Objectives

The Health and Retirement Study (HRS) was designed as an interdisciplinary study with a strong focus on health, retirement, and socioeconomic environment, to study their dynamic relationships over time in a sample of mid-life adults. The study includes validated self-report measures and individual items that capture the experiences of stressful events (stressor exposures) and subjective assessments of stress (perceived stress) within specific life domains.

Methods

This paper reviews and catalogs the peer-reviewed publications that have used the HRS to examine associations between psychological stress measures and psychological, physical health, and economic outcomes.

Results

We describe the research to date …


Neighborhood Cohesion, Neighborhood Disorder, And Cardiometabolic Risk, Jennifer N. Robinette, Susan T. Charles, Tara Gruenewald Dec 2017

Neighborhood Cohesion, Neighborhood Disorder, And Cardiometabolic Risk, Jennifer N. Robinette, Susan T. Charles, Tara Gruenewald

Psychology Faculty Articles and Research

Perceptions of neighborhood disorder (trash, vandalism) and cohesion (neighbors trust one another) are related to residents’ health. Affective and behavioral factors have been identified, but often in studies using geographically select samples. We use a nationally representative sample (n = 9032) of United States older adults from the Health and Retirement Study to examine cardiometabolic risk in relation to perceptions of neighborhood cohesion and disorder. Lower cohesion is significantly related to greater cardiometabolic risk in 2006/2008 and predicts greater risk four years later (2010/2012). The longitudinal relation is partially accounted for by anxiety and physical activity.


Discrimination And Anger Control As Pathways Linking Socioeconomic Disadvantage To Allostatic Load In Midlife, Samuele Zilioli, Ledina Imami, Anthony D. Ong, Mark A. Lumley, Tara Gruenewald Oct 2017

Discrimination And Anger Control As Pathways Linking Socioeconomic Disadvantage To Allostatic Load In Midlife, Samuele Zilioli, Ledina Imami, Anthony D. Ong, Mark A. Lumley, Tara Gruenewald

Psychology Faculty Articles and Research

Objective

Recent evidence suggests that experiences of discrimination contribute to socioeconomic status health disparities. The current study examined if the experience and regulation of anger—an expected emotional response to discrimination—serves as an explanatory factor for the previously documented links between socioeconomic disadvantage (SED), discrimination, and allostatic load.

Methods

Data were drawn from the second wave of the Midlife Development in the U.S. study and included 909 adults who participated in the biomarkers subproject.

Results

Results revealed that perceived discrimination was associated with higher levels of allostatic load. Furthermore, we found evidence that perceived discrimination and anger control sequentially explained the …


Prospective And Dyadic Associations Between Expectant Parents’ Prenatal Hormone Changes And Postpartum Parenting Outcomes, Robin S. Edelstein, William J. Chopik, Darby E. Saxbe, Britney M. Wardecker, Amy C. Moors, Onawa P. Labelle Sep 2016

Prospective And Dyadic Associations Between Expectant Parents’ Prenatal Hormone Changes And Postpartum Parenting Outcomes, Robin S. Edelstein, William J. Chopik, Darby E. Saxbe, Britney M. Wardecker, Amy C. Moors, Onawa P. Labelle

Psychology Faculty Articles and Research

During the transition to parenthood, both men and women experience hormone changes that are thought to promote parental care. Yet very few studies have explicitly tested the hypothesis that prenatal hormone changes are associated with postpartum parenting behavior. In a longitudinal study of 27 first-time expectant couples, we assessed whether prenatal hormone changes predicted self and partner-reported parenting outcomes at three months postpartum. Expectant fathers showed prenatal declines in testosterone and estradiol, and larger declines in these hormones predicted larger contributions to household and infant care tasks postpartum. Women whose partners showed larger testosterone declines also reported receiving more support …


Correlates Of Appearance And Weight Satisfaction In A U.S. National Sample: Personality, Attachment Style, Television Viewing, Self-Esteem, And Life Satisfaction, David Frederick, Gaganjyot Sandhu, Patrick J. Morse, Viren Swami May 2016

Correlates Of Appearance And Weight Satisfaction In A U.S. National Sample: Personality, Attachment Style, Television Viewing, Self-Esteem, And Life Satisfaction, David Frederick, Gaganjyot Sandhu, Patrick J. Morse, Viren Swami

Psychology Faculty Articles and Research

We examined the prevalence and correlates of satisfaction with appearance and weight. Participants (N = 12,176) completed an online survey posted on the NBCNews.com and Today.com websites. Few men and women were very to extremely dissatisfied with their physical appearances (6%; 9%), but feeling very to extremely dissatisfied with weight was more common (15%; 20%). Only about one-fourth of men and women felt very to extremely satisfied with their appearances (28%; 26%) and weights (24%; 20%). Men and women with higher body masses reported higher appearance and weight dissatisfaction. Dissatisfied people had higher Neuroticism, more preoccupied and fearful attachment …

Homophily, Close Friendship, And Life Satisfaction Among Gay, Lesbian, Heterosexual, And Bisexual Men And Women, Brian Joseph Gillespie, David Frederick, Lexi Harari, Christian Grov

Psychology Faculty Articles and Research

Friends play important roles throughout our lives by providing expressive, instrumental, and companionate support. We examined sexual orientation, gender, and age differences in the number of friends people can rely on for expressive, instrumental, and companionate support. Additionally, we examined the extent to which people relied on same-gender versus cross-gender friends for these types of support. Participants (N = 25,185) completed a survey via a popular news website. Sexual orientation differences in number of same-gender and cross-gender friends were generally small or non-existent, and satisfaction with friends was equally important to overall life satisfaction for all groups. However, the extent …


Unequally Distributed Psychological Assets: Are There Social Disparities In Optimism, Life Satisfaction, And Positive Affect?, Julia K. Boehm, Ying Chen, David R. Williams, Carol Ryff, Laura D. Kubzansky Jan 2015

Unequally Distributed Psychological Assets: Are There Social Disparities In Optimism, Life Satisfaction, And Positive Affect?, Julia K. Boehm, Ying Chen, David R. Williams, Carol Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

Socioeconomic status is associated with health disparities, but underlying psychosocial mechanisms have not been fully identified. Dispositional optimism may be a psychosocial process linking socioeconomic status with health. We hypothesized that lower optimism would be associated with greater social disadvantage and poorer social mobility. We also investigated whether life satisfaction and positive affect showed similar patterns. Participants from the Midlife in the United States study self-reported their optimism, satisfaction, positive affect, and socioeconomic status (gender, race/ethnicity, education, occupational class and prestige, income). Social disparities in optimism were evident. Optimistic individuals tended to be white and highly educated, had an educated …


Stranger Danger: Parenthood And Child Presence Increase The Envisioned Bodily Formidability Of Menacing Men, Daniel M.T. Fessler, Colin Holbrook, Jeremy S. Pollack, Jennifer Hahn-Holbrook Mar 2014

Stranger Danger: Parenthood And Child Presence Increase The Envisioned Bodily Formidability Of Menacing Men, Daniel M.T. Fessler, Colin Holbrook, Jeremy S. Pollack, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Due to altriciality and the importance of embodied capital, children’s fitness is contingent on parental investment. Injury suffered by a parent therefore degrades the parent’s fitness both by constraining reproduction and by diminishing the fitness of existing offspring. Due to the latter added cost, compared to non-parents, parents should be more cautious in hazardous situations, including potentially agonistic interactions. Prior research indicates that relative formidability is conceptualized in terms of size and strength. As erroneous under-estimation of a foe’s formidability heightens the risk of injury, parents should therefore conceptualize a potential antagonist as larger, stronger, and of more sinister intent …


Does Monogamy Harm Women? Deconstructing Monogamy With A Feminist Lens, Ali Ziegler, Jes L. Matsick, Amy C. Moors, Jennifer D. Rubin, Terri D. Conley Jan 2014

Does Monogamy Harm Women? Deconstructing Monogamy With A Feminist Lens, Ali Ziegler, Jes L. Matsick, Amy C. Moors, Jennifer D. Rubin, Terri D. Conley

Psychology Faculty Articles and Research

In this paper, we utilize a critical feminist lens to analyze the advantages and disadvantages found within two different romantic relationship configurations: monogamy and polyamory. While visibility of polyamorous relationships has increased in recent years, there is still a lack of information and a plethora of misinformation concerning non-monogamous romantic relationship dynamics (Conley, Moors, Matsick, & Ziegler, 2012; Conley, Ziegler, Moors, Matsick, & Valentine, 2012). One such notion is that polyamory is differentially damaging to women vis-à-vis men. From a phenomenological perspective, sociocultural values dictate that women, unlike men, are prescribed to be dependent upon monogamy in order to define …


It’S Not Just A Gay Male Thing: Sexual Minority Women And Men Are Equally Attracted To Consensual Non-Monogamy, Amy C. Moors, Jennifer D. Rubin, Jes L. Matsick, Ali Ziegler, Terri D. Conley Jan 2014

It’S Not Just A Gay Male Thing: Sexual Minority Women And Men Are Equally Attracted To Consensual Non-Monogamy, Amy C. Moors, Jennifer D. Rubin, Jes L. Matsick, Ali Ziegler, Terri D. Conley

Psychology Faculty Articles and Research

Concerned with the invisibility of non-gay male interests in alternatives to monogamy, the present study empirically examines three questions: Are there differences between female and male sexual minorities in a) attitudes toward consensual non-monogamy, and b) desire to engage in different types of consensual non-monogamy (e.g., sexual and romantic/polyamory versus sexual only/swinging), and c) schemas for love? An online community sample of lesbian, gay, and bisexual individuals (n = 111) were recruited for a study about attitudes toward relationships. Results show that sexual minority men and women hold similar attitudes toward CNM and similar levels of desire to engage in …


On The Margins: Considering Diversity Among Consensually Non-Monogamous Relationships, Jennifer D. Rubin, Amy C. Moors, Jes L. Matsick, Ali Ziegler, Terri D. Conley Jan 2014

On The Margins: Considering Diversity Among Consensually Non-Monogamous Relationships, Jennifer D. Rubin, Amy C. Moors, Jes L. Matsick, Ali Ziegler, Terri D. Conley

Psychology Faculty Articles and Research

Consensual non-monogamy (CNM) encompasses romantic relationships in which all partners agree that engaging in sexual and/or romantic relationships with other people is allowed and part of their relationship arrangement (Conley, Moors, Matsick & Ziegler, 2012). Previous research indicates that individuals who participate in CNM relationships are demographically homogenous (Sheff & Hammers, 2010; Sheff, 2005); however, we argue that this may be an artifact of community-based recruitment strategies that have created an inaccurate reflection of people who engage in CNM. To achieve a more nuanced understanding of the identities of individuals engaged in departures from monogamy, the present study provides a …


Social Norms, Discrete Choices, And False Dichotomies, Eric Schniter, Nathaniel Wilcox Jan 2012

Social Norms, Discrete Choices, And False Dichotomies, Eric Schniter, Nathaniel Wilcox

Psychology Faculty Articles and Research

Eric Schniter and Nathaniel Wilcox comment on Bram Tucker's article, "Do Risk and Time Experimental Choices Represent Individual Strategies for Coping with Poverty or Conformity to Social Norms? Evidence from Rural Southwestern Madagascar", which "revisits a debate played out in Current Anthropology as to whether subsistence decisions are the result of individual strategy to cope with poverty and increase wealth... or conformity to social norms."


Unconscious Vigilance: Worldview Defense Without Adaptations For Terror, Coalition Or Uncertainty Management, Colin Holbrook, Paulo Sousa, Jennifer Hahn-Holbrook Jan 2011

Unconscious Vigilance: Worldview Defense Without Adaptations For Terror, Coalition Or Uncertainty Management, Colin Holbrook, Paulo Sousa, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Individuals subtly reminded of death, coalitional challenges, or feelings of uncertainty display exaggerated preferences for affirmations and against criticisms of their cultural in-groups. Terror management, coalitional psychology, and uncertainty management theories postulate this “worldview defense” effect as the output of mechanisms evolved either to allay the fear of death, foster social support, or reduce anxiety by increasing adherence to cultural values. In 4 studies, we report evidence for an alternative perspective. We argue that worldview defense owes to unconscious vigilance, a state of accentuated reactivity to affective targets (which need not relate to cultural worldviews) that follows detection of subtle …


“I Would Feel Uncomfortable If My Child’S Teacher Were Gay”: Examining The Role Of Symbolic Homophobia And Political Affiliation, Michael Moore, Amy C. Moors Jan 2011

“I Would Feel Uncomfortable If My Child’S Teacher Were Gay”: Examining The Role Of Symbolic Homophobia And Political Affiliation, Michael Moore, Amy C. Moors

Psychology Faculty Articles and Research

Symbolic homophobia is a general negative disposition towards lesbian, gay, and bisexual individuals, which is demonstrated in symbolic forms of prejudice rather than overt actions. Stigma towards lesbian, gay, and bisexual (LGB) individuals has transformed from overt forms of prejudice to slightly less blatant more subtle forms in recent years (Schafer & Shaw, 2009). Based on previous research, it is has also been shown that conservatives will have higher levels of symbolic homophobia. (Linneman, 2004), Thus, in order to assess the more nuanced forms of prejudice in relation to political affiliation, Study 1 created a scale to assess symbolic homophobia. …


Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore Jan 2009

Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore

Psychology Faculty Articles and Research

A casual look at the literature in social cognition reveals a vast collection of biases, errors, violations of rational choice, and failures to maximize utility. One is tempted to draw the conclusion that the human mind is woefully muddled. We present a three-category evolutionary taxonomy of evidence of biases: biases are (a) heuristics, (b) error management effects, or (c) experimental artifacts. We conclude that much of the research on cognitive biases can be profitably reframed and understood in evolutionary terms. An adaptationist perspective suggests that the mind is remarkably well designed for important problems of survival and reproduction, and not …


Familialism, Social Support, And Stress: Positive Implications For Pregnant Latinas, Belinda Campos, Christine Dunkel Schetter, Cleopatra M. Abdou, Calvin J. Hobel, Laura M. Glynn, Curt A. Sandman Jan 2008

Familialism, Social Support, And Stress: Positive Implications For Pregnant Latinas, Belinda Campos, Christine Dunkel Schetter, Cleopatra M. Abdou, Calvin J. Hobel, Laura M. Glynn, Curt A. Sandman

Psychology Faculty Articles and Research

This study examined the association of familialism, a cultural value that emphasizes close family relationships, with social Support, stress, pregnancy anxiety, and infant birth weight. Foreign-born Latina (n = 31), U.S.-born Latina (n = 68), and European American (n = 166) women living in the United States participated in a prospective study of pregnancy in which they completed measures of familialism, social support, stress, and pregnancy anxiety during their second trimester. As expected, Latinas scored higher on familialism than European Americans. Familialism was positively correlated with social support and negatively correlated with stress and pregnancy anxiety in the overall sample. …


Nonlinear Dynamics And Interpersonal Correlates Of Verbal Turn-Taking Patterns In A Group Therapy Session, David Pincus, Stephen J. Guastello Dec 2005

Nonlinear Dynamics And Interpersonal Correlates Of Verbal Turn-Taking Patterns In A Group Therapy Session, David Pincus, Stephen J. Guastello

Psychology Faculty Articles and Research

Interpersonal processes and dynamics are ubiquitous topics in psychotherapy, yet they are difficult to study and are theoretically fragmented across therapeutic subdisciplines. The current study tests an integrative model of interpersonal dynamics in small groups using nonlinear dynamical systems theory. The conversation of one group therapy session (with six adolescent sex offenders) is analyzed using orbital decomposition, which allows for the identification of patterns in categorical time series data. The results show evidence of selforganizing social patterns, based on formal measures of turbulence (Lyapunov dimension), information novelty (Shannon's entropy), and complexity (fractal dimension). The degree of patterning in turn taking …
