de Carvalho, Marilia Pinhiero; Machado, Armando – Journal of the Experimental Analysis of Behavior, 2012
When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s,…

Schlund, Michael W.; Hoehn-Saric, Rudolf; Cataldo, Michael F. – Journal of the Experimental Analysis of Behavior, 2007
Forming new knowledge based on knowledge established through prior learning is a central feature of higher cognition that is captured in research on stimulus equivalence (SE). Numerous SE investigations show that reinforcing behavior under control of distinct sets of arbitrary conditional relations gives rise to stimulus control by new, "derived"…

Brembs, Bjorn; Wiener, Jan – Learning & Memory, 2006
In a permanently changing environment, it is by no means an easy task to distinguish potentially important events from negligible ones. Yet, to survive, every animal has to continuously face that challenge. How does the brain accomplish this feat? Building on previous work in "Drosophila melanogaster" visual learning, we have developed an…
