When discrete localizable stimuli are used during appetitive Pavlovian conditioning, "sign-tracking" and "goal-tracking" responses emerge. Sign-tracking is observed when conditioned responding is directed toward the CS, whereas goal-tracking manifests as responding directed to the site of expected reward delivery. These…

Research report of studies on state-dependent learning. Studies with animals indicate that conditioned learning responses formed by non-drugged animals do not transfer to the drug state and vice versa. Authors suggest that state-dependent learning may play casual role in drug abuse. Tested drug list included. (LK)

Using basic learning theory the S-R behaviorial approach to the formation of attitudes defines an attitude in terms of a conditioned anticipatory implicit response to a stimulus object. Described in this study is a model used to investigate observational learning of attitudes in a laboratory situation. (SM)

This study undertook to reconcile the views of cognitive and behavioral learning theorists on the issue whether learning without awareness (LWA) is possible, and if so, the circumstances under which it occurs. In Study One, two reinforcement procedures were compared in a structured verbal conditioning task. Study Two was a replication of Study…
