The chamber remains the same before and after the shock Loose set of cues belong together – animal can determine this about the room – hippocampus guides the animal to put all the cues together and remember the space of the chamber even though the cues aren’t filling the requirements of a strong CS Examples of Associative Conditioning Spatial Learning Rats dislike water so they try to get out of the bowl of murky water; there’s a platform which the rat must find. Once the rat finds the platform the experimenter removes the rat and puts it into a warm chamber which is considered a reward.
