Test Your Knowledge on Animal Memory and Forgetting

Consolidation is the process of transforming a short-term memory trace into a more durable long-term memory trace.

The three causes of forgetting discussed in Lecture 6 are proactive interference, retroactive interference, and decay.

Delayed matching to sample is a technique for studying delayed reaction. It is used to measure an animal's ability to remember a stimulus over a delay period.

<p>The radial arm maze is a means of presenting a list of items to the animal. The animal must remember which arms it has already visited in order to find the item at the end of the maze.</p> Signup and view all the answers

<p>Proactive interference is when previously learned information interferes with the ability to remember new information. It was observed in DMTS when one sample is immediately followed by the other.</p> Signup and view all the answers

<p>Retrieval is necessary for an animal to use a memory, as it allows them to access and use stored information.</p> Signup and view all the answers

<p>Retroactive interference is when new information interferes with the ability to remember previously learned information. It was observed in DMTS when the brightness with which the chamber is illuminated is increased during the delay between sample and comparison.</p> Signup and view all the answers

<p>Retrospective encoding is when an animal remembers information about a past event, while prospective encoding is when an animal anticipates future events based on past experiences. Animals can use both methods for remembering.</p> Signup and view all the answers

<p>Delayed matching to sample measures an animal's memory by presenting a stimulus, then delaying the presentation of a matching stimulus. The animal must remember the original stimulus in order to correctly match it with the new stimulus.</p> Signup and view all the answers
