Our WEISEST students, Shahd and Samantha, supervised by the excellent Moriah Deimeke and Prateek Sahu, presented their final poster today! Funding generously provided by NSERC, CRC, the Government of Alberta, Faculty of Arts and the Faculty of Science.

Congratulations, @prateek754 and the rest of the @SNLab2002 from @Psych_UAlberta on a fab new paper in @iScience_CP ! Sahu, P.K., et al. Vocal consistency is associated with auditory perceptual ability in a songbird. Manuscript to appear in iScience.

Congratulations to Sarah Smeltz who defended their MSc today! Funded by Natural Sciences and Engineering Research Council of Canada (NSERC) Tri-agency Institutional Programs Secretariat (TIPS) Government of Alberta University of Alberta Faculty of Science and Faculty of Arts !

MSc student Sarah Smeltz from the Songbird Neuroethology Laboratory and the Department of Psychology at the University of Alberta won the Comparative Cognition Society best publication by a graduate student award at the Conference on Comparative Cognition (photo: Mo Deimeke).

A new Registered Report Protocol by Prateek Sahu, @cbsturdy.bsky.social and colleagues pre-registers tests of whether female zebra finches prefer “long path length” songs, in order to re-examine earlier claims that this holistic song feature signals male quality.

Re-examining hidden fitness: Female preferences for long-path songs in zebra finches

Female songbirds can evaluate male quality from secondary sexual characteristics such as songs. Studies have shown mixed findings on which acoustic features contribute to song attractiveness. In a…

Evolving language: - Reports that HAQERS -- human-ancestor quickly evolved regions, acquired after split from chimpanzees -- influence language not general cognition - Via altered behind of Forkhead transcription factors (eg FOXP2) - Finds HAQERS-like seqs in other vocal learners #prattle 💬
