Sensation: the activation of the sense organs by a source of physical energy (sensing a bright light, sound, or a pinch)
Perception: the sorting out, interpretation, analysis, and integration of stimulus involving the sense organs and brain (eating a hot pepper or a sour patch kid)
Sensation and perception changes out body behavior, therefore psychologists study it
Telepathy: the term used to describe the ability to read other people’s minds
Stimulus: energy that produces a response
light is energy and can cause you to squint
gust of wind causes you to lose balance
Absolute threshold: minimum stimulation level an organism needs to sense a stimulus
lowest hearing point, can range from 20-30 db
Sensory adaption: where the body adjusts to external stimuli over time
exposed to perfume for an extended time can make u nose blind
Visual spectrum: humans can see very little
Five senses:
touch
taste
hear
smell
sight
ESP (Extra- Sensory Perception): belief that some people have knowledge of information that is not gained through the senses
Examples of ESP:
Telepathy - mental transfer of information from one person to another
Clairvoyance - medium (communicate with the dead) or finding lost people
Pre-Cognition - predicting future events
Intuition and Deja-vu - gut feeling/feeling that something has happened
SIGHT:
Peripheral vision: important for balance, safety (driving), sports
Tunnel vision: fear causes narrowing of the blind spot
Rods and Cones
Rods: microscopic structures in the eye that help you see in the dark
Cones: microscopic structures that help you see color
Light and Dark adaption
Light adaption: eyes adapting to bright light
Dark adaption: eyes adapting to a dark environment
our eyes can adapt quicker to a bright light then a dark environment
What happens when you have fewer or no cones?
Protanopia: blindness to the color red
Deuteranopia: blindness to the color green
Tritanopia: blindness to blue and yellow
Acromatopsia: color blindMemorize cornea, lens, blind spot, and optic nerve
The Gender Gap
average person can see 7 million colors
1/50 men are colorblind
1/5000 women are colorblind
Afterimage: an image that you seem to see when you are no longer looking at it or when it is no longer there
HEARING:
women are more attractive to deeper voices in men
men are more attractive to high voices
women can match faces with voices better than men
women cannot determine the height, weight, age, and social class by listening to someone’s voice
SMELL:
pheromone: natural occurring chemicals in the body released into the environment
flashbulb memory: a memory is triggered when one of the senses. this memory is so memorable because it was surprising, unexpected, and/or unusual
how smell impacts behavior:
it chooses where u want to go to eat
it chooses whether or not u want to stay in the room
women have a better sense of smell
mothers can identify their babies by a scent
woman who live together get synced menstrual cycles
it impacts attraction
women prefer the smell of men with different immune system
children would receive genetic coding of both parents and would therefore have a stronger immune system
PAIN:
Gate control theory: the theory that we can “open” and “close” the gate to pain using either artificial methods, learned methods, or natural methods
Artificial: pain medicines, magnets, surgery
these methods only mask the pain
Learned: lamaze, yoga, hypnosis, martial arts, acupuncture, suction cups, barney bandaid
Natural: release of endorphin adrenaline during stressful moments
fight or flight response
