When the strength of the indirect representation is greater than the direct one, the potential for inhibitory responding is larger than that for excitatory responding. According to Miller and Schachtman’s (1985) comparator hypothesis, LI is the consequence of a strong CS–CX association, acquired during preexposure, which makes the indirect representation of the US stronger than the direct one, therefore attenuating responding to the CS. According to Grahame et al. (1994), extinction of the training context following training results in decreased CX–US associations and the attenuation of LI, because it reduces the indirect representation of the US.
Extinction of CS2 following training results in decreased CS2–US associations and the attenuation of overshadowing, because of the reduced indirect representation of the US. According to the comparator hypothesis, blocking 15 16 Introduction of CS2 is the consequence of a strong CS1–US association, acquired during both phases of the experiment, which makes the indirect representation of the US (CS2–CS1 and CS1–US) stronger than the direct one (CS2–US), therefore attenuating responding to CS2. Extinction of CS1 following training results in decreased CS1–US associations and the attenuation of blocking, because of the reduced indirect representation of the US.
1989, page 118). 12] is not applicable when a suppression paradigm is used, because both appetitive and aversive behaviors are affected, and the effects possibly cancel out. 12] does not apply either (a) when the conditioned response is freezing, because both the CR and the OR work in the same direction; or (b) when the licking time in the presence of CS is measured, because the OR equally affects both the appetitive and aversive behavior. 12] is valid, however, when direct measures of behavior are reported using eyeblink conditioning, pecking in autoshaping or elevation scores.
