Sensation and Perception
This occurs when a stimulus (e.g., a sound, light, smell, touch or taste) is detected by receptors in your body.
sensation
Name three parts of the eye
Pupil, optic nerver, cornea, rods, cones, lens, Iris, etc
This is the snail shaped structure that transmits sound impulses to the brain
The cochlea
This starts at the very basic level of sensory receptors and works up to higher levels of processing.
Bottom-up processing
This is the weakest amount of a stimulus that can be sensed.
An Absolute threshold
This occurs when the brain receives the sensory input coming in from the body, organizes it, and interprets it.
Perception
These are the two photoreceptors in the eye
Rods and Cones
This is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing.
Cochlear implant
This occurs when the brain receives the sensory input coming in from the body, organizes it, and interprets it.
Top - Down processing
Our 5 senses take in 11 millions bits of information per second, but we only consciously process about 40 bits of info per second. This is called
Selective attention
Your visual sensors (retinas) ‘see’ a furry face and moving tail. This is an example of
Sensation
This allows us to see in Black and White.
Rods
This nerve transmits odors to the limbic system of the brain
olfactory nerve
If you see an image of an individual letter on your screen, your eyes transmit the information to your brain, and your brain puts all of this information together. This is
Bottom Up Processing
The belief that we distinguish and focus on different sensory stimuli based on their strengths, the setting we are in, our physical state, mood and attitude is called
Signal detection theory
Your ‘brain’ interprets your sensations, to recognize a happy dog. This is:
Perception
This allows us to see in color
Cones
What are the 5 basic taste qualities?
sweetness, sourness, saltiness, bitterness, Umani
Top-down processing
failing to see visible objects when our attention is directed elsewhere is called
in-attentional blindness
Your taste buds register a bitter sensation coming from a food source. This is:
sensation
This type of blindness is caused by missing or defective cones
Color Blindness
This is a type of deafness where people can’t hear loud enough - hearing aids can usually fix this.
Conductive deafness
This type of processing is experience driven, as opposed to stimulus driven
Top-down processing
Our diminished sensitivity to constant or routine odors, sounds, and touches, to focus our attention on information changes in stimulation.
