B&C: Memory

Question 1

What is LTP/ LTD?

Answer 1

• Long-Term Potentiation (LTP): long-lasting increase in communication between neurons.
• Long-Term Depression (LTD): long-lasting decrease in communication between neurons.

Question 2

What is the other neural principle of learning?

Answer 2

Pre-synaptic (more/less neurotransmitter release), post- synaptic (more/less sensitive), structural changes (more/less points of contact)

Question 3

What steps are involved in learning and memory?

Answer 3

Encoding
Consolidation
Retrieval

Question 4

What parts of the brain are involved in declarative memory?

Answer 4

Medial temporal lobe, diencephalon

Question 5

What parts of the brain are involved in procedural memory? (skills, habits)

Answer 5

Basal Ganglia

Question 6

What parts of the brain are involved in priming?

Answer 6

Neocortex

Question 7

What parts of the brain are involved in simple classical conditioning?

Answer 7

Amygdala, cerebellum

Question 8

What is the difference in a partial and full report Iconic memory test

Answer 8

In a full report you have to try report all 9 of the letters while in the partial report you only have to report the letters indicated afterwards by an arrow

Question 9

What is the result of this?

Answer 9

People will often report the whole row despite the arrows coming after the stimulus appears and a lack of ability to do this in a full report

Question 10

What factors influence this

Answer 10

If the cue appears immediately, people can report many items

If the cue appears later, performance deteriorates rapidly

Question 11

What do these results mean?

Answer 11

As the participant doesn’t know beforehand which row will be cued, all information needs to be kept in memory until the cue is presented
That’s why you can multiply the performance/capacity in the partial report condition by the amount of rows that has been presented.
