Introduction - Philosophy, Psychology And Neuroscience

Question 1

What is sensation?

Answer 1

The awarenss of physical stimulus through the senses

Question 2

What is perception?

Answer 2

The ability to apprehend or become aware of something through senses

Question 3

What’s the difference between sensation and preception?

Question 4

What is indirect realism?

Answer 4

• When you do not perceive objects directly.
• When you experience sensations and perceptions based on assumptions (physics, CNS processing, sensory detectors) that we deem reliable

Question 5

What is the representational model of the mind?

Answer 5

• The outer world: physics, mass, energy, molecules
• The inner world: mental states sights, sounds

Question 6

What can indirect realism lead to?
