Comparative Analysis Of Meissner's Corpuscles In The Fingertips Of Primates, A. Verendeev, C. Thomas, S. C. Mcfarlin, William D. Hopkins, Kimberley A. Phillips, Chet C. Sherwood Jul 2015

Comparative Analysis Of Meissner's Corpuscles In The Fingertips Of Primates, A. Verendeev, C. Thomas, S. C. Mcfarlin, William D. Hopkins, Kimberley A. Phillips, Chet C. Sherwood

Psychology Faculty Research

Meissner's corpuscles (MCs) are tactile mechanoreceptors found in the glabrous skin of primates, including fingertips. These receptors are characterized by sensitivity to light touch, and therefore might be associated with the evolution of manipulative abilities of the hands in primates. We examined MCs in different primate species, including common marmoset (Callithrix jacchus, n = 5), baboon (Papio anubis, n = 2), rhesus macaque (Macaca mulatta, n = 3), chimpanzee (Pan troglodytes, n = 3), bonobo (Pan paniscus, n = 1) and human (Homo sapiens, n = 8). Fingertips …


A Biometric Analysis Of Mate Choice Copying In People, Jonathan Lenhardt May 2015

A Biometric Analysis Of Mate Choice Copying In People, Jonathan Lenhardt

Theses, Dissertations and Culminating Projects

Mate choice copying is the notion that a person or animal, after observing another choosing a romantic or sexual partner, will perceive that partner as more attractive and possibly attempt to acquire that same partner for themselves. Using measurement of pupil size in response to the presentation of pictures of men and women both alone and with a neutral or admiring partner, it was hypothesized that such a biometric measure could substantiate previous research that has supported the evidence of mate choice copying in people. This study's methodology complements that of previous studies utilizing questionnaires to measure the attractiveness of …


Tractography Of The Spider Monkey (Ateles Geoffroyi) Corpus Callosum Using Diffusion Tensor Magnetic Resonance Imaging, D. Platas-Neri, S. Hidalgo-Tobón, B. De Celis Alonso, F. C-P De León, J. Muñoz-Delgado, Kimberley A. Phillips Feb 2015

Tractography Of The Spider Monkey (Ateles Geoffroyi) Corpus Callosum Using Diffusion Tensor Magnetic Resonance Imaging, D. Platas-Neri, S. Hidalgo-Tobón, B. De Celis Alonso, F. C-P De León, J. Muñoz-Delgado, Kimberley A. Phillips

Psychology Faculty Research

The objective of this research was to describe the organization, connectivity and microstructure of the corpus callosum of the spider monkey (Ateles geoffroyi). Non-invasive magnetic resonance imaging and diffusion-tensor imaging were obtained from three subjects using a 3T Philips scanner. We hypothesized that the arrangement of fibers in spider monkeys would be similar to that observed in other non-human primates. A repeated measure (n = 3) of fractional anisotropy values was obtained of each subject and for each callosal subdivision. Measurements of the diffusion properties of corpus callosum fibers exhibited a similar pattern to those reported in the …


Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster Jan 2015

Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster

Psychology Faculty Publications

Although collective action has psychological benefits in non-gendered contexts (e.g., Drury et al., 2005), the benefits for women taking action against gender discrimination are unclear. This study examined how a popular, yet unexplored potential form of collective action, namely tweeting about sexism, affects women’s well-being. Women read about sexism and were randomly assigned to tweet, or to one of three control groups. Content analyses showed tweets exhibited collective intent and action. Analyses of linguistic markers suggested public tweeters used more cognitive complexity in their language than private tweeters. Profile analyses showed that compared to controls, only public tweeters showed decreasing …


Parental Conversation Styles And Learning Science With Preschoolers, Emily A. Stone Jan 2015

Parental Conversation Styles And Learning Science With Preschoolers, Emily A. Stone

Honors Theses and Capstones

Preschool children participated in a science-learning event about light in their own classroom. The same day as the event, parents or caregivers were instructed to converse with their children at home in the evening about either the science learning event or another ‘special or fun’ event that happened to them recently in whatever way was natural for them. One week later, a researcher interviewed children to examine what they remembered about the science-learning event. Analyses focused on the impact of the topic and degree of elaboration of parent-child conversations on children’s memory for the science-learning event a week later. The …


Assessing Suicide Risk Scores As A Predictor Of Suicidal Behaviors In A Correctional Psychiatric Facility, Janice Rice Jan 2015

Assessing Suicide Risk Scores As A Predictor Of Suicidal Behaviors In A Correctional Psychiatric Facility, Janice Rice

Antioch University Dissertations & Theses

This study evaluated suicide risk assessments in a correctional psychiatric setting. It considered whether clinicians’ judgment of suicide risk predicted future suicidal behaviors in seriously mentally ill prisoners. Data analysis did not show that higher suicide risk scores predicted more suicidal behaviors, nor did it show that suicide risk scores differentiated multiple attempters, or those who went on to attempt suicide or self-harm two or more times in the three years following the assessment. Study data did, however show that suicide risk scores significantly differentiated those who went on to attempt suicide or self-harm at least once in the three …


The Interpersonal Theory Of Suicide Applied To Male Prisoners, Jon T. Mandracchia, Phillip N. Smith Jan 2015

The Interpersonal Theory Of Suicide Applied To Male Prisoners, Jon T. Mandracchia, Phillip N. Smith

Faculty Publications

The interpersonal theory of suicide proposes that severe suicide ideation is caused by the combination of thwarted belongingness (TB) and perceived burdensomeness (PB), yet few studies have actually examined their interaction. Further, no studies have examined this proposal in male prisoners, a particularly at-risk group. To address this gap, the current study surveyed 399 male prisoners. TB and PB interacted to predict suicide ideation while controlling for depression and hopelessness. High levels of both TB and PB were associated with more severe suicide ideation. The interpersonal theory may aid in the detection, prevention, and treatment of suicide risk in prisoners.
