Egfr May Couple Moderate Alcohol Consumption To Increased Breast Cancer Risk, Christopher P. Mill, Julia Chester, David J. Riese Ii
Egfr May Couple Moderate Alcohol Consumption To Increased Breast Cancer Risk, Christopher P. Mill, Julia Chester, David J. Riese Ii
Department of Psychological Sciences Faculty Publications
Alcohol consumption is an established risk factor for breast cancer. Nonetheless, the mechanism by which alcohol contributes to breast tumor initiation or progression has yet to be definitively established. Studies using cultured human tumor cell lines have identified signaling molecules that may contribute to the effects of alcohol, including reactive oxygen species and other ethanol metabolites, matrix metalloproteases, the ErbB2/Her2/Neu receptor tyrosine kinase, cytoplasmic protein kinases, adenylate cyclase, E-cadherins, estrogen receptor, and a variety of transcription factors. Emerging data suggest that the epidermal growth factor receptor (EGFR) tyrosine kinase may contribute to breast cancer genesis and progression. Here we integrate …
Sibling Death And Death Fear In Relation To Depressive Symptomatology In Older Adults, Victor G. Cicirelli
Sibling Death And Death Fear In Relation To Depressive Symptomatology In Older Adults, Victor G. Cicirelli
Department of Psychological Sciences Faculty Publications
Previously overlooked factors in elders’ depressive symptomatology were examined, including death fear, sibling death, and sibling closeness. Participants were 150 elders (61 men, 89 women) aged 65 to 97 with at least one sibling. Measures were: proportion of deceased siblings, sibling closeness, the Death Fear subscale of the DAP-Revised, and the CES-D depression scale (20-item adult form). Age and education were exogenous variables in a structural equation model. Death fear, sibling closeness, and proportion of dead siblings were directly related to depression, with path coefficients of .42, -.24, and .13, respectively. Proportion of dead siblings had indirect effects on depression, …
Extensive Training Is Insufficient To Produce The Work-Ethic Effect In Pigeons, Marco Vasconcelos, Peter J. Urcuioli
Extensive Training Is Insufficient To Produce The Work-Ethic Effect In Pigeons, Marco Vasconcelos, Peter J. Urcuioli
Department of Psychological Sciences Faculty Publications
Zentall and Singer (2007a) hypothesized that our failure to replicate the work-ethic effect in pigeons (Vasconcelos, Urcuioli, & Lionello-DeNolf, 2007) was due to insufficient overtraining following acquisition of the high- and low-effort discriminations. We tested this hypothesis using the original work-ethic procedure (Experiment 1) and one similar to that used with starlings (Experiment 2) by providing at least 60 overtraining sessions. Despite this extensive overtraining, neither experiment revealed a significant preference for stimuli obtained after high effort. Together with other findings, these data support our contention that pigeons do not reliably show a work-ethic effect.

Satisfaction, Alternatives, Investments And The Microfoundations Of Audience Cost Models, Aaron M. Hoffman, Christopher Agnew, Justin Lehmiller, Natasha T. Duncan
Satisfaction, Alternatives, Investments And The Microfoundations Of Audience Cost Models, Aaron M. Hoffman, Christopher Agnew, Justin Lehmiller, Natasha T. Duncan
Department of Psychological Sciences Faculty Publications
In this paper, we suggest that the Investment Model of Commitment, developed in social psychology, offers a solution to an important microfoundational issue in audience cost theory. Audience cost models are useful for thinking about the foreign policy behaviors of democratic and non-democratic states. However, they often assume that citizens reliably penalize leaders who break their foreign policy promises even though the empirical record suggests this is not always the case. We argue that public commitment to foreign policy assets and relationships is a precondition for the application of audience costs. Using the U.N. and NATO as case studies, we …

Non-Marital Romantic Relationship Commitment And Leave Behavior: The Mediating Role Of Dissolution Consideration, Laura E Vanderdrift, Christopher Agnew, Juan E. Wilson
Non-Marital Romantic Relationship Commitment And Leave Behavior: The Mediating Role Of Dissolution Consideration, Laura E Vanderdrift, Christopher Agnew, Juan E. Wilson
Department of Psychological Sciences Faculty Publications
Two studies investigated the process by which individuals in non-marital romantic relationships characterized by low commitment move toward enacting leave behaviors. Predictions based on the behavioral, goal, and implementation intention literatures were tested using a measure of dissolution consideration developed for this research. Dissolution consideration assesses how salient relationship termination is for an individual while one’s relationship is intact. Study 1 developed and validated a measure of dissolution consideration and Study 2 was a longitudinal test of the utility of dissolution consideration in predicting the enactment of leave behaviors. Results indicated that dissolution consideration mediates the association between commitment and …

The current diagnostic system suggests that personality disorder categories be applied to children and adolescents in rare circumstances because of expected changes in personality pathology across development. The present study examined the stability in personality pathology, specifically psychopathy, across childhood and adolescence. Using a short form of the CPS and mixed models incorporating fixed and random effects, we examined the reliability, individual stability, mean-level stability, and predictive utility of juvenile psychopathy as a function of age (i.e., from 7 to 17 years old) in over 1,500 boys from the three cohorts of the Pittsburgh Youth Study. If adolescent development contributes …
Kicking To Bigger Uprights: Field Goal Kicking Performance Influences Perceived Size., Jessica Witt, Travis E. Dorsch
Kicking To Bigger Uprights: Field Goal Kicking Performance Influences Perceived Size., Jessica Witt, Travis E. Dorsch
Department of Psychological Sciences Faculty Publications
Perception relates not only to the optical information from the environment but also to the perceiver’s performance on a given task. We present evidence that the perceived height and width of an American-football field goal post relates to the perceiver’s kicking performance. Participants who made more successful kicks perceived the field goal posts to be farther apart and perceived the crossbar to be closer to the ground compared with participants who made fewer kicks. Interestingly, the current results show perceptual effects related to performance only after kicking the football but not before kicking. We also found that the types of …
Similarity In Cigarette Smoking Attracts: A Prospective Study Of Romantic Partner Selection By Own Smoking, Smoker Prototype, And Perceived Approval, Paul Etcheverry, Christopher Agnew
Similarity In Cigarette Smoking Attracts: A Prospective Study Of Romantic Partner Selection By Own Smoking, Smoker Prototype, And Perceived Approval, Paul Etcheverry, Christopher Agnew
Department of Psychological Sciences Faculty Publications
The current research employs a multi-wave longitudinal design to examine how young adults' own smoking, smoker prototypes, and perceived partner approval of smoking are associated with selection of romantic partners over time. Results indicate that participants who smoke and have a more positive prototype of the typical smoker are more likely to initiate a romantic relationship with someone who smokes and who has greater perceived approval for smoking. The findings suggest the importance of examining romantic partner factors associated with young adult smoking and suggest some important aspects of selection effects in terms of the target of selection (romantic partners), …
