FINAL (Chapter 4 on) Flashcards
(20 cards)
Sensation
The stimulation (activation) of the sense organs
Perception
The selection, organization, and interpretation of that sensory input
Identical twins vs Fraternal twins
Identical twins are more related
Auditory system
Hearing
Olfactory and Gustatory systems
Smell, taste, and flavour
Both chemical sense
Sense of smell doesn’t go through the thalamus (IMPORTANT)
Touch senses
Pain, Temperature, Shape, Texture
Kinesthetic and Vestibular
Systems
Balance and Orientation
Visual systems
Seeing
What are stimuli for hearing
soundwaves
What are the stimuli for vision
lightwaves
The parallels between loudness of sound =
brightness of light
Which of the following is a chemical sense
Olfactory or gustatory
Transduction:
Change stimulus from something in physical environment to a neural signal
Sensory Adaption
A gradual decline in sensitivity to specific stimulation due to prolonged exposure
Absolute Threshold:
For a specific type of sensory input, the MINIMUM amount of stimulation that an organism can DETECT
Attention
The concentration of our awareness
on some stimuli to the exclusion of others
Sound waves
vibrations of molecules that travel through a medium, such as air
Light waves
form of electromagnetic radiation that travels as a wave
FAST PAIN
Detects localized pain and relays it to the cortex in a fraction of a second
* A-delta fibres: Quick, sharp pain
* Send signals “where” information to somatosensory cortex
SLOW PAIN
Detects the less localized, longer lasting, aching or burning pain
* C-fibres: Long, dull pain
* Sends motivational information to hypothalamus, amygdala, and frontal lobe
