Document Summary

If this is true we should see other effects when we inactivate the. Ofc: blocking study: learning about certain cues will be blocked because those cues are somewhat redundant: a compound cue (ax) results in food delivery, animals learn this, check food port whenever they see. Which cue: knowledge of the predictive value of cue a" can potentially block new learning. Ofc inactivation did not influence this learning, which indicates it is not needed to learn simple cue-reward associations: cues x and y are completely new to the rats. Cue c has been seen before but has no association with food. Inferred predictive value of cue a blocked learning about cue x: cue x was considered to be somewhat redundant because cue a was known to predict cue b which was known to predict food drops. And since no value was inferred for cue.
