Physiological Measures (4a)

Question 1

2 nervous systems

Answer 1

central nervous system
peripheral nervous system

Question 2

parts of the CNS

Answer 2

brain
nerves in spinal cord

Question 3

parts of the PNS

Answer 3

nerves and ganglia outside the brain and spinal cord

Question 4

2 types of PNS

Answer 4

somatic nervous system
autonomic nervous system

Question 5

somatic nervous system (SNS)

Answer 5

voluntary control of sense and muscle movement

Question 6

autonomic nervous system (ANS)

Answer 6

• subconscious body control
• controls visceral functions (e.g.,g heart, respiration rates, digestion, pupil dilation, sexual arousal)

Question 7

afferent

Answer 7

into CNS

Question 8

efferent

Answer 8

out of CNS

Question 9

2 parts of autonomic nervous system

Answer 9

parasympathetic nervous system
sympathetic nervous system

Question 10

nervous system for rest and digestion

Answer 10

parasympathetic nervous system

Question 11

nervous system for flight, fight of freeze

Answer 11

sympathetic nervous system

Question 12

2 dimensional model of valence and arousal

Answer 12

high/ low arousal - energy
negative/ positive valence

Question 13

arousal measures

Answer 13

• activation/ intensity/ tension/ vigor
• the activity of autonomic and somatic nervous system

Question 14

arousal measures methods

Answer 14

• electrocardigram
• photoplethysmography
• electroderman activity
• respiratory and breathing rate belts
• electrooculagraphy
• eye-tracking

Question 15

most common approaches for heart monitoring

Answer 15

electrocardiogram (ECG)

Question 16

photoplethusmograph (PPG)

Answer 16

• measures reflection of the illuminated light from an oximeter onto the skin
• monitors the changes of the absorption of light resulted from blood-volume’s changes

Question 17

advantages of PPG

Answer 17

• able to detect the cardiac cycle from the area of the skin where the PPG is applied to
• close proximity to the surface of skin
• does not rely on electrical activity
• unobtrusive
• cost effective
• effortless applications

Question 18

disadvantages of PPG

Answer 18

• signal less detailed
• can be subjected to noise artefacts
• effect of other physiological parameters that can affect the blood flow

Question 19

measurements/ signal features from ECG and PPG

Answer 19

• R-R intervals
• heart rate (bpm / variability)
• blood pressure
• breathing rate

Question 20

valence measures: body movements

Answer 20

• head and body tracking technologies
• via microscopic sensory that can be emdedded in wearable solutions and clothing
  inertial measurement unit

Question 21

the evaluative space model

Answer 21

• general model of valence of evaluative experience
• suggests that the experience of valence comprises 2 affective components

Question 22

2 affective components of the evaluative space model

Answer 22

• appetitive
• aversive
• impact our predispositions towards and against them
