Classically Conditioned Licking And Acquired Orienting As A Function Of Qualitatively Different Ucs Values : Acquisition, Shifting And Extinction, Jerry Weeks Rudy

Master's Theses

The purpose of the present study was twofold: (A) to study classically conditioned licking in rats as a function of a qualitative UCS difference, defined as 15% sucrose concentration and 0% concentration (plain tap water); (B) to study acquired orienting as a function of these UCS values. Several aspects of conditioned performance were investigated: (1) the effect of UCS intensity on level of responding during acquisition; (2) the effect of UCS intensity on rate of approach to terminal level of responding; (3) a possible learning performance distinction in appetitive classical conditioning; (4) rate of extinction as a function of the …
