Pedagogy

 

As an educator, my primary objectives are to provide an engaging atmosphere for learning and to impart the importance of assessing psychological research from a critical and analytic perspective.  I encourage students to pursue their own intellectual interests within the area of psychology. I also feel it is important to provide students with multiple opportunities to succeed.  I bring to class a variety of active learning approaches including group projects, multimedia lectures, in-class demonstrations, and group discussion (adaptable to small or large class enrollments).   Learning occurs through linkages between the student’s personal knowledge and experience and the current issues and contexts of social, political, and psychobiological relevance.  It is my hope that each course ignites the student scholar’s enthusiasm and curiosity for the subject. I attempt to recruit interest through a little theater, my own passion and research of the subject, and applied examples.  One way to encourage others to appreciate a discipline is to experience the process of constructing a theoretical question, collecting data, and interpreting through statistical analysis the results; therefore it is important to me that students experience research as part of their instructional experience. 

 

Research Interests

 

My background is in comparative, behavioral neuroscience; therefore I investigate similarities in behavior between species.  Consequently I adhere to an evolutionary and neurocognitive theoretical model.  The majority of my published research thus far is within the area of risk-sensitivity, sensation-seeking, self-control, behavioral endocrinology, and psychometric reliability (RELGEN) of personality measures (e.g. Zuckerman’s Sensation Seeking Scales, Form V, Buss-Perry Aggression Questionnaire, Yale-Brown Obsessive Compulsive Scale).  All of these projects flourish only through the involvement of undergraduate research assistants.  Interested, responsible scholars are encouraged to contact me at the onset of the semester to learn what projects are underway.

 

Current Research Projects

 

Validation of the Fisher-Island Neurochemistry Typology

Pacific University, Department of Psychology, Forest Grove, OR

Rutgers University, Department of Physical Anthropology, New Brunswick, NJ

ZRT Laboratory, Beaverton, OR

Chemistry.com (Match.com Group), Dallas, TX

August 2006 – Present

The purpose of this study is to 1.) analyze the validity and reliability of a newly developed typology measure Fisher-Island Typology; and 2.) compare college student scores on this measure with their assayed hormones and neurotransmitters (e.g. testosterone, estradiol,  progesterone, free androgen index, sex hormone binding globulin, DHEA, serotonin, and dopamine) for commercial and empirical use.

 

Speed dating and Nonverbal Leakage of Liking and Disdain

Pacific University, Department of Psychology, Forest Grove, OR

8minute Dating, Gresham, OR

September 2006 – Present

The purpose of this study is to observe nonverbal leakage of participants during Speed Dating venues and compare the approval relative to the disapproval leakage to the selection of suitors following their interactions.  This study has wide reaching implications, the established criteria of liking and disliking are based on the published work of Monica Moore that has not been empirically validated.

Reliability Generalization: Yale-Brown Obsessive-Compulsive Questionnaire

Pacific University, Department of Psychology., Forest Grove, OR

September 2006 – Present

This meta-analytic investigation is of the published reliabilities of the Aggression Questionnaire to assess measure reliability. Student authors: Jessica Carter and Stephanie Miyasaki

Courses I Teach...

 

At Pacific University, all faculty teach a variety of different courses. Typically, we do not use graduate teaching assistants, which means that your classes will be taught by professors and that you will have plenty of opportunites to get to know the faculty in your discipline.

Below, I have listed some of the courses that I teach. We are always developing and trying out new classes, so the list may change now and then. You can use the links to the left to read descriptions of the courses listed below.

 

PSY 150 Introductory Psychology
PSY 255 Comparative Animal Learning
PSY 252 Biological Psychology (Behavioral Neuroscience)
PSY 348/9 Research Methods & Lab
