Unit 3: Sensation and Perception - Coggle Diagram
Unit 3: Sensation and Perception
: the ditence between each peak
: determine by wavelength
: determine by amplitude
: the hight
wavelength: blueish color 🟢 🔵 🟣
wavelength: reddish color. 🔴 🟠 🟡
of our eye ball
: the adjustment, light come in
: change shape help to focus on retina
The lens focuses the rays by changing its curvature in a process called
: the light sensitive surface, resive the up side down image
: black, white, and grey color, periphery, high capture with dim light, low capture of color, low capture of details
: daily, light, detail
carries neural impulses from the eye to the brain.
a place on retina, optic nerve leaves the eye, creating a “blind” spot because no receptor cells are located there.
: the central focal point in the retina, around which the eye’s cones cluster
: determine your eye color, control how long Pupil open
Visual information processing
: light ➡️rod and cones ➡️Bipolar cell ➡️ganglion cell ➡️ optic nerve ➡️visual area of thalamus ➡️occipital lobe ➡️feature detectors➡️ Parallel processing➡️recognization
: nerve that detect specific element such as shape
processing: process manythings at the same time
Young Helmholtz trichromatic ( Three color) theory
: red green blue
Opponent Processing Theory
: red&green, blue&yellow
: an organized whole
:We perceive smooth, continuous patterns rather than discontinuous ones.
: we group the same shape together
: We group nearby figures together.
: We fill in gaps to create a complete, whole object
:nfants and young animals
epth cues, such as retinal disparity, that depend on the use of two eyes.
difference between two eye can tell us how depth
: depth cues, such as interposition and linear perspective, available to either eye alone.
Light and shadow
: erceiving objects as unchanging
: perceiving familiar objects as having consistent color
: the largest sense organ
depends on the lengths if the path to the brain
tells us we are in danger
Gate control theory
contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain.
small: activities and open the gate
large: shut the gate
: Bio, social, psy
sensation and perception
: detect physical energy from the environment.
: het the information by giving meaning by organizing of interpreting sensation
: sensory receptors ➡️higher level
: experience and expectation➡️sensory and perception. we interpret what our senses detect
: the focusing of conscious awareness on particular stimulus :red_cross: 👀
fail to notice the changing
: blind to their own choice
fail to see one object because your attention is not there
conversion of one from of energy to another
: relationships between two subject
threshold: at lets 50% energy can be detected
the stimuli that cannot be detected 50%
Signal detection theory
: predicts when we will detect weak signals.
seek to understand why people respond differently to the same stimuli
: the unconsciously activation of certain associations, thus predisposing one’s perception, memory, or response.
threshold: at 50% of difference can be detected
: for an average person to perceive a difference, two stimuli must differ by a constant minimum percentage
:you will be adapt and loss some sensitivity of the stimuli if you constantly feel it
Influence on Perception
a set of ,metal tendencies that greatly affect our perception
: sound waves traveling through
Protruding hair cells
Motion of fluid in the cochlea
Auditory nerve ➡️ Auditory cortex
organ of Corti: a structure in the cochlea of the inner ear which produces nerve impulses in response to sound vibrations.
conduction hearing loss:
damage to the mechanical system , damage in the process
sensorineural hearing loss
: damage to cochlear
sour🧃 ➡️possible toxic
sweet🍭 🍬 ➡️energy
bitter🥵 ➡️possible poisons
tongue⏩200 or more taste buds
each taste bud➡️50 to 100 taste receptor cells
: odor molecules oder ants bind to receptors➡️ receptor ➡️axons ➡️ brain
Age and gender with smell
Smell and memory
Anosmia➡️ complete loss of the ability of smell
: Body position and movement 🤸♂️
a vestibular sense
involve eye and
vestibular sacs: awareness of body balance in ear
