SENSATION VS. PERCEPTION
When sensory information is detected by a sensory receptor
WHAT IS SENSATION?
The transparent covering over the eye.
WHAT IS THE CORNEA?
A fluid-filled, snail-shaped structure that contains the sensory receptor cells (hair cells) of the auditory system
WHAT IS THE COCHLEA?
These two senses are called chemical senses because both have sensory receptors that respond to molecules in the food we eat or in the air we breathe.
WHAT ARE OLFACTION AND GUSTATION?
Literally means form or pattern
WHAT IS GESTALT?
The conversion from sensory stimulus energy to action potential
WHAT IS TRANSDUCTION?
Specialized types of photoreceptors that work best in bright light conditions.
WHAT ARE CONES?
This theory of pitch perception asserts that frequency is coded by the activity level of a sensory neuron.
WHAT IS THE TEMPORAL THEORY?
A Japanese word that roughly translates to yummy, and it is associated with a taste for monosodium glutamate
WHAT IS UMAMI?
This principle asserts that things that are close to one another tend to be grouped together
WHAT IS PROXIMITY?
The minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time.
WHAT IS THE ABSOLUTE THRESHOLD?
The optic nerve from each eye merges just below the brain at this point
WHAT IS THE OPTIC CHIASM?
The partial or complete inability to hear.
WHAT IS DEAFNESS?
These sensory receptors have a life cycle of ten days to two weeks
WHAT ARE TASTE BUDS?
We organize our perceptions into complete objects rather than as a series of parts
WHAT IS THE PRINCIPLE OF CLOSURE?
The way sensory information is organized, interpreted, and consciously experienced.
WHAT IS PERCEPTION?
According to this theory, color is coded in opponent pairs: black-white, yellow-blue, and green-red.
WHAT IS THE OPPONENT-PROCESS THEORY OF COLOR PERCEPTION?
This disease results in a degeneration of inner ear structures thatcan lead to hearing loss, tinnitus (constant ringing or buzzing),vertigo(a sense of spinning), and an increasein pressure within the inner ear
WHAT IS MENIERE'S DISEASE?
A signal indicating potential harm and maybe pain
WHAT IS NOCICEPTION?
Our ability to discriminate among different figures and shapes,
WHAT IS PATTERN PERCEPTION?
We often don’t perceive stimuli that remain relatively constant over prolonged periods of time.
WHAT IS SENSORY ADAPTATION?
Our ability to perceive spatial relationships in three-dimensional (3-D) space
WHAT IS DEPTH PERCEPTION?
In deaf culture, the primary mode of communication
WHAT IS SIGNING?
Contributes to our ability to maintain balance and body posture.
WHAT IS THE VESTIBULAR SENSE?
Educated guesses that we make while interpreting sensory information.
WHAT IS PERCEPTUAL HYPOTHESIS?
