Welcome to the SPEL Website!

The Social Psychoneuroendocrinology Lab (SPEL) examines interactions between hormones, the environment, and human social behavior with an emphasis on status hierarchies, decision-making, and emotion regulation/stress.

Our lab integrates methods from the psychological sciences with neuroscience methods (hormone measurement and administration, neuroimaging, cardiovascular responses, genotype, etc.) to understand these processes.

SPELab produces its first Ph.Ds! Two more to come soon!

Congrats to Jason & Erik for successfully defending their dissertations recently.  And good luck to Smrithi & Colton, who defend their dissertations soon!

SPELab welcomes our new post-doc, Dr. Kathleen Casto!

1/2/2017

 
SPELab is proud to welcome the newest member of the team, Kathleen Casto. Dr. Casto joins us from Emory University where she worked with David Edwards on the social endocrinology of groups with a special focus on sports. She will be leading new research in the lab on testosterone, cortisol, and group dynamics. We can't wait to challenge her to a foot race (with a 20-30 sec. head start for the rest of us). Welcome aboard Dr. Casto!

Hot off the presses: New work in PNAS!

Exciting new work from the lab in Proceedings of the National Academy of Sciences showing that hierarchy stability moderates the effects of social status on the cortisol, testosterone, and behavioral responses to social-evaluative stress. (Link or pdf).

New Doctoral Student and New Papers!

10/31/2016

 
A big SPELab welcome to Sarah Donaldson, our newest member of the SPELab team who successfully completed her First Year Project talk last week! She hasn't assayed her testosterone and cortisol levels yet, but she will be in a high status position before you know it! Congrats and welcome aboard!

New papers out from SPELab research! (Check out Publications page for more details and PDFs)
  • Testosterone x Cortisol stress response predicts decisions in the Ultimatum Game! (Prasad et al., (in press))
  • What do we know about what we know about salivary testosterone immunoassays? Here's a paper that compares commercially available salivary assay kits to tandem mass spectrometry. If you're collecting spit for research (or other reasons), you'll want to check it out! (Welker et al., 2016)
  • Hormone profiles of small groups predict performance? Wow-zah! (Akinola et al., 2016)

Open Science Collaboration Paper (Featuring Pranj and Bethany) is Published in Science

9/1/2015

 
Picture
"Estimating the reproducibility of psychological science" by the Open Science Collaboration has just been published in the August 28th issue of Science.  The article features 100 studies conducted by 270 researchers (including Dr. Mehta and lab alumna, Bethany Lassetter), with the intention of replicating studies previously published in one of three major peer-reviewed psychological journals.  As such, the collaboration makes a notable advancement in the transparency and reliability of psychological science.
