Perception And Memory

Question 1

What are the 3 segregations of objects?

Answer 1

~Perceptual organisation into figure and ground
~Perceptual organisation of Stimuli into coherent patterns
~Closure

Question 2

What are the three cues which perception of distance relies on?

Answer 2

~relative sizes
~Superimposition
~Relative height in the field

Question 3

What happens during Binocular Disparity?

Answer 3

Each eye receives a slightly different image from an object. The brain then merges the two images. This allows us to judge distance

Question 4

Memories include….

Answer 4

Past experiences, knowledge and thought.

Question 5

3 steps in using memory

Answer 5

Storage
Retention
Retrieval

Question 6

Info entering the brain passes into…..

Answer 6

Sensory memory

Question 7

How long do visual images last for?

Answer 7

0.5s

Question 8

How long do auditory images last for?

Answer 8

2s

Question 9

How long can info be stored in STM for?

Answer 9

30s

Question 10

Info can either be stored in the STM or ….

Answer 10

Transferred to LTM
Lost by displacement
Lost by decay

Question 11

Why would info get lost by decay in the STM?

Answer 11

Too few neurons have been stimulated so the info is weak

Question 12

Working memory can be…?

Answer 12

Manipulated

Question 13

What are the features of STM

Answer 13

Memory span
Chunking
Rehearsal
Serial position effect

Question 14

How do you get info from STM to LTM

Answer 14

Rehearsal
Organisation
Elaboration

Question 15

To transfer a peice of info from STM to LTM….

Answer 15

It has to be encoded

Question 16

What is shallow encoding

Answer 16

The result of rehearsal. The larger info is held in the STM, the higher the chance it will be encoded

Question 17

Explain elaborate encoding

Answer 17

If info is linked to previous memories, it is organised into logical categories. This organisation leads to elaborate encoding.

Question 18

How would retrieval from the LTM be easier?

Answer 18

If it has been stored under many different contexts.

Question 19

What are the 5 contexts

Answer 19

Episodic
Semantic
Spatial
Procedural 
Emotional

Question 20

Where are episodic and semantic memories stored?

Answer 20

In the area of the cortex where the sensory info was received and encoded

Question 21

What is perception?

Answer 21

The process by which the brain analysis incoming information from sensory neurons and makes sense of it
