memory

Question 1

define processing

Answer 1

the operations we perform on sensory information in the brain.

Question 2

define input

Answer 2

for human memory; this refers to the sensory info we receive from our environment.

Question 3

what are the 5 senses

Answer 3

• sight
• hearing
• touch
• taste
• smell

Question 4

define storage

Answer 4

the retention of info in our memory system.

Question 5

define encoding & 3 types of encoding

Answer 5

turning sensory info into a form that can be used & stored by the brain.
* acoustic encoding
* visual encoding
* semantic encoding

Question 6

define acoustic encoding

Answer 6

the process of storing sound in our memory system.

Question 7

define visual encoding

Answer 7

the process of storing something that we’ve seen in our memory system.

Question 8

define semantic encoding

Answer 8

the process of storing the meaning of info in our memory system
e.g rather then sound of a word, we store definition of the word.

Question 9

define output

Answer 9

refers to the info we recall; in a broader sense output can refer to behavioral response

Question 10

define retrieval

Answer 10

the recall of stored memories.

Question 11

define stm

Answer 11

our inital memory store that’s temporary & limited.

Question 12

define ltm

Answer 12

memory store that holds potentially limitless amounts of info for up to a long time.

Question 13

define duration

Answer 13

length of time info can be stored in stm & ltm

Question 14

define capacity

Answer 14

amount of info can be stored in stm & ltm.

Question 15

where does sensory info first enter?

Answer 15

• stm

Question 16

what’s the duration & capacity of stm?
encoding?

Answer 16

duration: 15-30 seconds w/o rehearsal
capacity: 7+-2 items
encoding: acoustic through rehearsal of info, can be stored for many mins then transferred to ltm

Question 17

duration & capacity of ltm?
& encoding

Answer 17

duration: for minutes or up to a lifetime
capacity: unlimited amount of info
encoding: largely semantic. can be visual or acoustic.

Question 18

define displacement

Answer 18

when stm becomes full & new info pushes out older info.

Question 19

define interference

Answer 19

when new info overwrites older info
e.g when new phone no takes place of old no in your memory.

Question 20

define amnesia

Answer 20

memory loss, often through accident, disease, injury.

Question 21

define anterograde amnesia

Answer 21

a memory condition that means new long-term memories can’t be made; this is typically caused by injury to the brain.

Question 22

define retrograde amnesia

Answer 22

a memory condition that affects recall of memories prior to an injury of the brain.
