Weeks 1, 2 and 3

Question 1

What is perception

Answer 1

An unconscious automatic neural process which occures through inferences of cues, and sometimes consiouss effort is used to interprest when data is imcomplete of ambiguous

Question 2

Describe the perceptual process

Answer 2

Enviromental stimuli is transducted, transmitted and processed to allow perception which recognises and object and permits action in responce to it

Question 3

What does effortless of perceptions mean

Answer 3

Although we percive with ease, the percpetual process is complicated.

Question 4

What is distal stimuli

Answer 4

This is when light is reflected from an object and hits visual receptors

Question 5

What is proximal/attended stimuli?

Answer 5

This is after the distal stumili reaches the eye. The cornea and lens bend the light to shape the image on the Retina

Question 6

Describe the principle of transformatiom

Answer 6

Perception of an object will change based on the amount of light, the atmosphere and all other factors present during the distal and proximal phases of the perceptual process

Question 7

What is the principle of representation

Answer 7

Everything we see is not based on what actually there but the repesenation of it in our mind

Question 8

What is the receptor process during the perceptual process (transduction)

Answer 8

when light hit visual receptors they are activated and transform this light energy into chemical energy.

Question 9

What is the neural processing part of the perceptual process. Describe the strength of the signals

Answer 9

This is when the electrical signals travel from the brain via the optic chiasm. While some signal strengthen others get weaker

Question 10

What is the percpetion part of the neural process

Answer 10

This is when we become aware that we are seeing something

Question 11

What is the recognition part of the perceptual process

Answer 11

this is when the object is recognised by placing into a catergorey which gives it meaning

Question 12

what happens in the action part of the perceptual process

Answer 12

this is when motor responces occue as a result of the object

Question 13

Describe the difference between sensation and perception

Answer 13

Sensation is the feeling the object evokes in you while perception is the higher order function which explains the sensation

Question 14

Provide and example of sensation followed by perception

Answer 14

Feeling something cool, and knowing it was the wind blowing on you

Question 15

Explain the flow of infomation in the brain for site

Answer 15

Signals ar recived in the primary recieving area of the occitipal lobe and then sent to the frontal lobe

Question 16

destinguish between top down and bottom up processing

Answer 16

bottom up is when stimuli provides and starting point for perception while top down is perception based on prior knowledge

Question 17

What is the method for equiring qualitive data?

Answer 17

gaingin a description of ones own perception

Question 18

What is grating acuity

Answer 18

The smallest differences between the grating of lines which is percievable by a person.

Question 19

What is the oblique effect

Answer 19

That is people see lines best when they are horizontal or vertical than any other lines not at horizontal or vertical orientations

Question 20

What is qauntitve data, give an example

Answer 20

This is when the parameters of perception are measured using numbers. For example, how wll can you hear this tone from one to 10
