Welcome to the Neiworth Primate Cognition Lab!

This is our 26th year of working with tamarins at Carleton College and we lost our last elderly monkey (Oriole) on June 23, 2024. Rest in peace, our queen Oriole! We are still compiling data on the tamarins' cognitive and perceptual abilities, and will be posting archival video footage and new publications here, as well as our work to donate important support/supplies to new homes!

We cared for and worked with:

  • 32 monkeys that have spanned over three generations

  • About 156 undergraduate collaborators to date 

  • Five NIH grants, totaling $1.7 million dollars and

  • More than 2 dozen publications and presentations

Watch the new video "Celebrating 35 years with Julie" in which alumni share how they benefit from their Carleton experiences in Julie's classes and lab!

This research is sponsored in part by grants from the National Institute of Health, by summer research support from the Howard Hughes Medical Institute, by a Eugster Fellow Award, and by Carleton College.
