dc.description.abstract | Three experiments explored the link between
reward shifts and latent inhibition (LI). Using consummatory
procedures, rewards were either downshifted
from 32% to 4% sucrose (Experiments 1–2), or
upshifted from 4% to 32% sucrose (Experiment 3). In
both cases, appropriate unshifted controls were also included.
LI was implemented in terms of fear conditioning
involving a single tone-shock pairing after extensive
tone-only preexposure. Nonpreexposed controls were also
included. Experiment 1 demonstrated a typical LI effect
(i.e., disruption of fear conditioning after preexposure to the
tone) in animals previously exposed only to 4% sucrose.
However, the LI effect was eliminated by preexposure to a
32%-to-4% sucrose devaluation. Experiment 2 replicated
this effect when the LI protocol was administered immediately
after the reward devaluation event. However, LI was
restored when preexposure was administered after a 60-
min retention interval. Finally, Experiment 3 showed that
a reward upshift did not affect LI. These results point to a
significant role of negative emotion related to reward devaluation
in the enhancement of stimulus processing despite
extensive nonreinforced preexposure experience. | es |
