Intro

Question 1

Perceptual Process

Answer 1

• ## Environmental stimuli -> light is reflected and transformed -> receptor process and neural processing allow for perception and recognition which is followed by the corresponding action

Question 2

Transduction

Answer 2

transformation of environmental energy into electrical energy by sensory receptors (NOT ALL STIMULI IS EXTERNAL)

Question 3

Receptor process

Answer 3

1. environmental stim
2. light is reflected and transformed
3. receptor processes (rods and cones)
   - sensory receptors - cells specialized to respond to environmental energy with each sensory’s system receptors specialized to respond to specific stim

Question 4

Neural processing

Answer 4

4. receptor cells -> subcortical brain areas -> cortical brain areas -> other brain areas
   - signals are transmitted from receptors to the brain and changed along the way
   - intracortical processing transforms sensory data into percepts

Question 5

Perception to action

Answer 5

5. peception (electrical signals are transformed in consious awarness)
6. recognitoin
7. action

Question 6

Difference between sensation and perception

Answer 6

sensation - sensory processes detect info from the physical world and transform into biological signals from the brain
perception - signal unified awarness of a stimulus that arises from sensation produced by our sensory systems; which gives meaning to the detected sensation
