Performance,cardiovascular, and health behavior effects of an inhibitory strength training intervention

Female undergraduates were assigned to one of three groups, two involving regulatory training and one not. Training participants performed for 2 weeks tasks that required strong behavioral restraint (Strong Training) or weak behavioral restraint (Weak Training). Later, they took part in (1) a laboratory session in which they performed tasks with inhibitory components, and (2) a follow-up week in which they provided health behavior reports and used designated dental supplies. No Training participants took part only in the session and follow-up week. As expected, laboratory performance was improved for Strong- relative to No Training participants, with performance for Weak Training participants falling in between. Also as expected, Strong Training participants used more floss in the follow-up week than did the No Training participants, with floss for Weak Training participants falling between. Contrary to expectation, Strong Training participants used less toothpaste and reported having brushed less than the No Training participants. In addition, Strong Training participants evinced exaggerated—rather than diminished—cardiovascular responses during the laboratory tasks. The performance and floss use data support the suggestion that inhibitory system strength can be increased through use. The brushing and cardiovascular findings may be interpretable in inhibitory strength terms.     

Memory issues pertaining to social marketing messages about behavior enactment versus non-enactment

This article examines efficiency issues pertaining to social marketing messages about behavior enactment (e.g., smoker) vs. non-enactment (e.g., nonsmoker). Building on a wealth of psycholinguistics research, we posit that underlying differences in the processing and storage of word concepts with affixal negations affect learning and memory for these concepts (i.e., associations with non-enactment concepts will be harder to learn and remember than associations with enactment concepts). Two experiments support our predictions, suggesting that messages about enactment will demonstrate superior efficiency. Implications of study findings are discussed in terms of possibilities for improving the efficiency of social marketing messages about non-enactment.     

Assessing ADHD-related Family Stressors with the Disruptive Behavior Stress Inventory (DBSI): A Replication and Extension

The Disruptive Behavior Stress Inventory (DBSI) was developed to provide information related to the occurrence and severity of stressors that result from having a child with ADHD. Data provided in the initial 2002 study by Johnson and Reader (Journal of Clinical Psychology in Medical Settings, 9, 51–62) provided good preliminary support for the reliability of the DBSI, as well the ability of the scale scores to differentiate primary caregivers of children with and without a history of ADHD. The present study was an attempt to replicate major findings of the 2002 study using an additional larger sample and extend it by conducting item-level analyses to determine the degree to which individual DBSI items differentiate primary caregivers of children with and without a history of ADHD. Results provided additional support for the reliability and validity of the DBSI by replicating major findings from the 2002 study and further suggesting that a large majority of the 40 items individually differentiate between primary caregivers of children with and without a history of ADHD.     

Relative judgment and knowledge of the category structure

For evenly spaced stimuli, a purely relative judgment account of unidimensional categorization performance is trivial: All that is required is knowledge of the size of stimulus difference corresponding to the width of a category. For unevenly spaced stimuli, long-term knowledge of the category structure is required. In the present article, we will argue that such knowledge does not necessitate a direct, absolute mapping between (representations of ) stimulus magnitudes and category labels. We will show that Stewart, Brown, and Chater’s (2005) relative judgment model can account for data from absolute identification experiments with uneven stimulus spacing.     

The Ethics of Conducting Community-Engaged Homelessness Research

This paper focuses on some of the ethical issues which may arise when conducting research in the context of homelessness. These issues are considered from the viewpoints of researchers, research coordinators and interviewers, drawing from their extensive real world experience. In addition to negotiating the complex context of homelessness, community-based homelessness researchers need to address a number of ethical issues in research conception, design, implementation and dissemination. Although these issues are commonly considered in community-engaged research, research with people who are homeless may raise exceptional challenges. Such challenges include determining the nature of informed consent; protecting research participants and researchers, and determining appropriate compensation for participation. Understanding the context of homelessness to conduct ethical research will require sharing information and joint decision-making, processes that must include members of communities within which the research participants live. Furthermore, researchers should be sensitive to the changing context of homelessness, and vigilant for new ethical challenges.     

Personal Political Salience: The Role of Personality in Collective Identity and Action

Personal political salience (PPS) is proposed as a personality characteristic that assesses individuals' linkage of political events with their personal identities. Its role in facilitating the development of politicized collective identity and action is examined. In four samples of midlife and activist women, we show that PPS was consistently related both to politicized gender identity and political participation. Further analyses show similar results for PPS, politicized racial identity, and political participation. Politicized gender identity mediated the relationship between PPS and women's rights activism, and politicized racial identity mediated the relationship between PPS and civil rights activism. PPS is demonstrated to independently predict political action and also to provide a personality link between group memberships, politicized collective identity, and political participation.     

On the relationship between Karen Horney's tripartite neurotic type theory and personality disorder features

[Horney, 1945] and [Horney, 1950] interpersonal theory [Horney, K. (1945). Our inner conflicts. New York, NY: W. W. Norton & Co., Inc.; Horney, K. (1950). Neurosis and human growth. New York, NY: W. W. Norton & Co., Inc.] postulated that individuals could move toward, move against, and move away from others as manifestations of their character development. In the present studies, it was hypothesized that Horney's tripartite theory might be useful in the elucidation of Diagnostic and Statistical Manual of Mental Disorders personality disorder features. In the first study, college students (n=198) completed the Coolidge Axis II Inventory [CATI; Coolidge, F. L. (1999), Coolidge Assessment Battery Manual. Port Huron, MI: Sigma Assessment Systems and Coolidge, F. L., & Merwin, M. M. (1992). Reliability and viability of the Coolidge Axis II Inventory: a new inventory for the assessment of personality disorders. Journal of Personality Assessment, 59, 223–238] and Cohen's 1967 35-item test [Cohen, J. B. (1967). An interpersonal orientation to the study of consumer behaviour. Journal of Marketing Research, 4, 270–278] of Horney's three types: Compliant, Aggressive, and Detached. In the second study, another group of college students (n=881) completed the CATI and Coolidge's 57-item test of Horney's three types. Results showed that both scales were reliable, generally similar, and numerous predicted correlational relationships were found. The usefulness of Horney's constructs in the understanding of personality disorders was discussed.     

Smoking in College Women: The Role of Thinness Pressures, Media Exposure, and Critical Consciousness

There are strong social pressures for U.S. females, particularly those of European heritage, to achieve and maintain an extremely low body weight. These pressures are reflected in a variety of media sources, including advertising. We argue that valuing thinness, exposure to thinness-depicting media, and lacking skepticism about tobacco advertisements have adverse effects on young women's decisions about smoking, particularly smoking for weight control. We tested these hypotheses in a study of 188 female undergraduates, both never-smokers and daily smokers. Believing that smoking controls weight, exposure to thinness-depicting media, and low levels of skepticism about tobacco advertising were associated with being a smoker. Among smokers, believing that smoking controls weight, internalizing thinness pressures, and low levels of feminist consciousness were associated with smoking for weight control. Results are discussed with the aim of encouraging public health anti-smoking campaigns targeted at women, and smoking cessation programs that are responsive to the needs of weight-concerned female smokers.     

Middle Aging in Women: Patterns of Personality Change from the 30s to the 50s

This three-sample study focused on changes in four key features of women's personalities (identity, generativity, confident power, and concern about aging) over the course of middle age. Based on women's retrospective and concurrent feelings about their lives in their 30s, 40s, and 50s, scales were developed and validated for the four themes. We found that identity certainty, generativity, confident power, and concern about aging all were experienced as more prominent in middle age (the 40s) than in early adulthood (the 30s). We also found that these elements of personality were rated even higher in the 50s than the 40s. Scores seemed to be a function of age more than historical period or particular experiences in social roles. Scores on identity certainty, generativity, and confident power were positively related to well-being, while concern about aging was negatively related to well-being.
