Maier receives Society of Neuroscience Career Award. Congratulations Alex!

September 3, 2014—Assistant Professor of Psychology Alexander Maier has been selected to receive the Society for Neuroscience's Janett Rosenberg Trubatch Career Development Award for 2014. The purpose of the award, which is given to only two individuals each year, is "to recognize individuals who have demonstrated originality and creativity in research and to promote success during academic transitions prior to tenure." Maier was recognized for his efforts to understand the basic mystery of how perception arises from neural activities. A prime focus of his research program is to differentiate between the neural circuitry that is involved in visual perception and sensory activity that does not attain the level of conscious awareness. His work has important implications for treating patients with visual disorders characterized by an inability to perceive or recognize certain types of visual images. He is also one of a handful of scientists studying the relationship between the electrical activity in the brain and the variations in blood flow that are measured by the brain mapping technique fMRI, the most commonly used and most reliable method for measuring neural responses in the human brain- Recipients receive a $2,000 award and complimentary registration to the society's annual meeting.


Braden Purcell wins honorable mention for James McKeen Cattell Award

August 15, 2014—Braden's PhD dissertation, Neural Mechanisms of Perceptual Decision Making, has been chosen to receive honorable mention in the 2013-2014 James McKeen Cattell Dissertation competition sponsored by the Psychology Section of the New York Academy of Sciences. The field was highly competitive, with many excellent candidates for the award. His work was highly regarded by the reviewers and by the Steering Committee. The Academy further commended the work of his mentors, Thomas Palmeri and Jeffrey Schall, and the graduate program in Psychological Sciences at Vanderbilt University. In recognition of his noteworthy achievement, he will receive a certificate from the New York Academy of Sciences; his mentors will be similarly recognized. Congratulations Braden!


Elizabeth Dykens' research featured in the Times!

July 30, 2014—Dr. Elizabeth Dykens' research on reducing distress among caregivers of developmentally delayed children has been featured in the New York Times. Dr. Dykens and colleagues conducted a randomized trial published in Pediatrics comparing effects of mindfulness training and positive psychology practice on mothers' stress, depression, and anxiety. More about the study can be found here http://www.ncbi.nlm.nih.gov/pubmed/?term=miodrag+autism and the Times article "When the Caregivers Need Healing" can be found here http://www.nytimes.com/2014/07/29/health/when-the-caregivers-need-healing.html?_r=0 . Congratulations Dr. Dykens!

The odds ratio and its alternatives: Measure-specificity of effects

Andrew Tomarken, Vanderbilt Department of Psychology

The odds ratio (OR) is among the most commonly used statistical measures of association or effect. It is by far the most commonly reported measure when dependent variables are binary and it is ubiquitous in studies focusing on the association between risk factors and disease outcomes. Unfortunately, most scientists are largely unaware of the mathematical and statistical properties of the OR and its differences, strengths, and weaknesses relative to alternative measures. After discussing several historical reasons for the popularity of the OR, I will describe several common misinterpretations and mistaken assumptions made by researchers based on an ongoing review of published research in medical and psychological journals. At various points, comparisons will be made to two alternative measures of effect, the relative risk (RR) and the risk difference (RD). Two overriding points will be emphasized: (1) Conclusions about the nature, functional form, and magnitude of effects derived from the OR will often not generalize to alternatives. Thus exclusive reliance on the OR can provide a highly selective or even misleading picture of the phenomenon under study; and, (2) Different measures are sensitive to different features of data, and at a more fundamental level, may reflect differing -- yet almost always unstated -- assumptions about the nature of main effects and interactions. I will conclude that: (1) It is important for researchers to determine those measures and models that best fit the goals of the study, the conceptualization of risk, and other aspects of the substantive phenomenon under investigation; (2) In the absence of a clearly optimal choice, researchers should report multiple measures to provide a more complete picture of the effects of predictors on binary measures; and, (3) Researchers need to expand on the cryptic verbal descriptions typically offered to describe effects and to supplement the presentation with appropriate graphical and other tools.
