Lecture 1:

Question 1

Transduction

Answer 1

The process by which individual sense organs convert (transduce) energy from any environmental events into neural activity.

Question 2

Transmission

Answer 2

Carries the signals from the receptors to the brain and around the brain.

Question 3

Bottom-Up Processing (3)

Answer 3

• Flow of information from the environment through the sensory systems towards the brain
• Processing based on incoming stimuli from the environment
• Data-based processing

Question 4

Top-Down Processing (3)

Answer 4

• From the brain towards the lower areas in the brain
• Processing based on the perceiver’s previous knowledge (cognitive factors)
• Knowledge-based processing

Question 5

Psychophysical approach (2)

Answer 5

• The stimulus-perception relationship
• Study the relationship between your perceptions as a function of changing physical properties

Question 6

Physiological approach (PH1) (2)

Answer 6

• The stimulus-physiology relationship
• By recording the activity of individual neurons you record the electricity as a function of systematically manipulating stimuli in the outside world, this gives insight into how neurons in the brain process information

Question 7

Physiological approach (PH2) (2)

Answer 7

• The physiology and perception relationship
• Measuring the activity of many neurons together but in a particular brain area, and try to deduce how information could be represented
