Sensation and Perception Flashcards
Sensation VS Perception
Sensation: Physical stimuli to neurological signals
Perception: Processing sensory information to make sense of its significance
How does it work
Sensory receptors respond and trigger electrical signals
Sensory neurons transmit information to the CNS
Sensory stimuli are transmitted to projection areas
Threshold
Minimum stimulus that causes a change in signal transduction
Weber’s Law
The proportion of the just noticeable difference is constant
Signal Detection Theory
Signal Present: Yes / No
Signal Absent: Yes / No
Signal Present: Yes / No
Hit/Miss
Signal Absent: Yes / No
False Alarm/Correct Negative

Receptors/Nerves Used to Smell
Olfactory Chemoreceptors/Nerves
Taste
Taste buds in papillae
Somatosensation
Temperature, Pain, Pressure, Vibration
Parietal Lobe
Kinesthetic
Tell where one’s body is in space
Proprioception
Bottom Up Processing
What am I seeing? Attention to detail
Top Down Processing
Have I seen this before? No attention to detail
