Resumen:
In one experiment with rats, we examined whether positive affective
states can serve as contexts in a betweensubjects ABA renewal design
using appetitive instrumental conditioning. Two groups of rats received
training to press a lever for food where each acquisition session was
preceded by administration of a tickling procedure (Context A) known to
induce positive affective states. Then, lever pressing underwent
extinction where rats received a pure handling treatment (Context B)
before each session. During a final test session, we found stronger
responding when the session was preceded by tickling (Group ABA)
compared to handling (Group ABB), indicating an ABA renewal effect.
Furthermore, test performance in Group ABB was not different from that
in a third group where handling preceded acquisition sessions, and
tickling extinction and test sessions (Group BAA), showing that tickling
did not elevate instrumental responding during the test if it had been
unrelated to initial acquisition. We discuss implications of our results
for understanding the role of positive affective states in relapse of
problem behavior.
