Hard limits to cognitive flexibility in ants, data set + meta data

Wenig, K., Bach, R., & Czaczkes, T. J. (2021). Hard limits to cognitive flexibility: ants can learn to ignore but not avoid pheromone trails. Journal of Experimental Biology (2021) 224, jeb242454. doi:10.1242/jeb.242454

experiment1 - learning to avoid pheromone trails (punishment: quinine)2 - learning to avoid pheromone trails (punishment: quinine + shock)3 - learning to avoid pheromone trails, go/no-go approach4 - learning to avoid an odour
