Flashcards in Ch.7 Deck (29):
1

H.M.'s strange condition with being unable to learn new things taught psychology that memories are stored ??? in the brain.

normally and abnormally

2

Memory is the Nervous System's capacity to ? and ? skills and knowledge

retain



retrieve

3

The processing of information so that it can be stored

encoding

4

the retention of encoded representations over time

storage

5

the neural process by which encoded information becomes stored in memory

consolidation

6

the act of recalling or remembering stored info when it is needed

retrieval

7

The multiple processes of memory can be thought of as operating over time in three phases
1. ?
2. ?
3. ?

Encoding



storage



retrieval

8

Strengthening of a synaptic connection, making the postsynaptic neurons more easily activated by presynaptic neurons

Long term potentiation LTP

9

? is distributed throughout the brain rather than confined to any specific location which is known as ?

Memory


equipotentiality

10

HDAC an epigenetic mechanism involves a class of enzymes which in inhibit gene expression. Also known as a "break pad". Drugs that block HDAC increase LTP.

Histone deacetylases

11

? happens happens each time a memory is activated and placed back in storage. It may explain why our memories for events can change over time.

Reconsolidating

12

? is distributed across the many brain areas, including the hippocampus, medial temporal lobes, and cortical sensory areas.

Memory

13

Consolidation is which phase of memory.

Storage

14

Long-term potentiation provides evidence for Hebb's concept that "cells that fire together wire together" T/F

True

15

The hippocampus is the only area of the brain required for memory T/F

False

16

Damage to the hippocampus results in amnesia for some but not all events

True

17

Reconsolidation offers one model for understanding why memories are not always accurate

True

18

Areas of the cortex such as the temporal lobes and sensory areas are not involved in memory

False

19

Once information is consolidated and stored, the memory will last for the animal's lifetime

False

20

Is a temporary memory system closely tied to the sensory systems

sensory memory

21

When we pay attention to something, the information passes from sensory stores to ?? ?. It briefly holds a limited amount of information in awareness.

short-term memory

22

An active processing system that keeps different types of information avail for current use

working memory

23

Sensory memory persists for about ? of a second and then progressively ?

1/3


fades

24

The process of breaking down info into meaningful units is known as ?

chunking

25

When people talk about memory they are usually referring to the relatively permanent storage of information : ?? ?

Long-term memory

26

The idea that the ability to recall items from a list depends on the order of presentation, with items presented early or late in the list remembered better than those in the middle

Serial position effect

27

?? stores info from each of the 5 senses for less than on e second enabling the brain to perceive the word as a continuous stream. Iconic memory is visual sensory memory. Echoic memory is auditory ??

Sensory memory


sensory memory.

28

Information can be held in working memory for ? to ? seconds. Working memory span is approximately seven items (plus or minus two).

20 to 30

29

Decisions about how to chunk info depends on ?
