About This Project

Unintentional injury due to risk-taking is a leading cause of death in the U.S. and places large burdens on society. We know that risk-taking is influenced by hormone response to stress. Variations of oxytocin receptor gene OXTR rs53576 influence stress sensitivity, and are influenced by social contexts. We hypothesize that GG-allele carriers will take less risks than A-allele carriers, but that this will be reversed when stressed. Results are expected to be influenced by sex and demographics.

What is the context of this research?

The adaptive calibration model of stress responsivity has indicated that behaviors (including risk-taking) can vary based on biological response to environment. Further, stress sensitivity and risk-taking propensity can be influenced by early relationships with parents, and emotion regulation. Emerging studies indicate that stress responsivity and sensitivity to social relationships can vary based on the oxytocin receptor gene OXTR rs53576. Because many of the unintentional injuries caused by risk-taking can lead to death, and are seen to be more prevalent in areas of high-stress, the current study is designed to understand how the relationship between stress, social relationships, and risk-taking can be moderated by OXTR rs53576.

What is the significance of this project?

Research has indicated that risk-taking is linked to both hormonal and social environmental cues, but research designed to understand the genetic underpinning of risk-taking is lacking and unintentional injury is still one of the leading causes of death today. To the best of our knowledge, this project will be one of the first studies to examine the role of the oxytocin receptor gene (OXTR rs53576) in risk-taking behaviors.

The findings from this project will provide an improved understanding of the influence of biological and environmental factors. If our hypothesis is supported, the results may allow for practitioners to create more effective prevention education programs to promote healthy societies by reducing the levels of risk-taking behaviors that lead to serious injury, infection.

What are the goals of the project?

Our first hypothesis is that there will be a significant difference in risk-taking between participants in the stress and no-stress groups. Male participants in the stress group will engage in more risk-taking than participants in the no-stress groups. This will be reversed for females. We expect the relationship between stress and risk-taking to be mediated by cortisol secretion and moderated by OXTR rs53576.

Our second hypothesis is that relationships with parents will mediate the cortisol secretion during the stressor and risk-taking tasks. We expect that participants reporting more parental warmth will engage in more emotion regulation and less risk-taking when exposed to stressors. We expect that the influence of parent-child relationships will differ based on OXTR rs53576.

Budget

Please wait...

We are asking for $4,950 for the analysis of the DNA component of our study. While the supplies to collect DNA are not expensive and have been paid for using small research grants and scholarships through Oklahoma State University, DNA analysis is critical for the success of the study and the study cannot be completed without additional funding.

The $4,950 will be used to assist with the cost of the following three items:

1) The overnight shipment of 150 collected DNA samples to Salimetrics Laboratories in State College, PA

2) Materials needed for the single nucleotide polymorphism (SNP) analysis that will occur after DNA extraction.

3) To pay the scientist provided by Salimetrics Laboratories who will extract and conduct the SNP analyses on the 150 collected DNA samples. A total of $2,000 is requested because Salimetrics charges $250 per unit of scientist time and eight units of scientist time are needed to have all samples analyzed.

This exciting project will help us better understand the determinants of risk-taking behavior, and its costs and benefits.
This project will yield important results, shedding new light on the biological basis of risk-taking and how one's biological predispositions toward risk-taking may be modified by early childhood environment. The researcher is a rising star in developmental psychobio research. Please take a moment to consider supporting this worthy project!

Our project began data collection in the Spring of 2018. Using a University SONA system, we have almost completed data collection on 150 participants. Our next step is to analyze the DNA and cortisol components of the study. We plan to have our manuscript submitted by May 2019. We will provide backers with a manuscript copy of our results at this time.

Team Bio

This project will be conducted by members of the Cognitive Science Laboratory at Oklahoma State University. Our team is conducted of a group of undergraduate students who are interested in the biological and social basis of behavior. More information about our team can be found here.

Erin Wood

My name is Erin Wood, and I am a graduate student at Oklahoma State University. I am a third year student in the Experimental Psychology Ph.D Program with options in development and comparative neurobiology studying under Dr. Shelia Kennison. As a developmental psychologist in training, my recent research has focused on the role that parents play in the development of risk-taking of their early childhood-aged and young adult children. Although parents play a large role in the development of risk-taking behaviors, by increasing my exposure to the literature in the field in my graduate training, I have realized that many of our behaviors are influenced by our biology. By taking a biopsychological approach to risk-taking I hope to find better explanations to the relationships between parents and children to promote resiliency and health.

In addition to conducting research to promote resiliency and health, I also have a passion for mentorship. As the laboratory manager for the Cognitive Science Laboratory, I am active in encouraging underrepresented populations to enter into STEM research careers by mentoring females, minorities, non-traditional, and first generation students. As a mentor, I encourage my students to present at research conferences, apply for scholarships and grants, or enter into their own graduate programs. My hope that is that my research will not only benefit science by providing a deeper understanding of the biological underpinnings of human behavior, but I hope that my research will also inspire my undergraduate research assistants to pursue graduate education in STEM fields to further expand the field of psychology.

You can learn more about me here. My published work can be found here.
