the comparative communication lab


The Comparative Communication Laboratory

The University of Tennessee - Knoxville

2015-2016 members include: David Book, Brittany Coppinger, Elizabeth Hobson (NIMBioS postdoctoral researcher), Trey Johnson, Hwayoung Jung, Steven Kyle, Kimberly Olson, Phylicia Washington, & Todd Freeberg


Our research seeks to understand how social processes influence communication. We test the roles of social groups on vocal signaling in chickadees and titmice (Paridae), taking developmental, mechanistic, and functional approaches.


Recent and ongoing projects in the lab include:

  • testing the roles of group size and complexity of social interactions on vocal signaling
  • tests of individuals' responses to predator behavior and facial / body orientation
  • determining the functions of variation in the 'chick-a-dee' call of chickadees and titmice
  • uncovering the relationships among social context, 'personality', and communication in chickadees and titmice
