Sensation and Perception
The receptors located in the sensory organs
Sensory receptors
The weakest amount of stimulus that can be sensed 50% of the time
The black circle you see when you look into someone's eye
What is the pupil
Determined by the height or amplitude of sound waves
What is loudness
The four basic groupings of taste
Sweet, salty, sour and bitter
Perceiving the world around us by drawing from what we already know in order to interpret new information
What is top-down processing
The minimum amount of difference that can be detected between two stimuli 50% of the time
What is the difference threshold
Electromagnetic energy; described in wave lengths
What is light
A bony tube that contains fluids and neurons that can move in response to the vibrations of fluids
What is the cochlea
True or false
Taste buds are formed by groupings of taste receptor cells
What is true
The process by which our 5 senses gather information and send it to the brain
What is sensation
The method of distinguishing sensory stimuli that takes into account not only the stimuli's strengths but other variables as well
What is signal detection theory
The part of the eye that adjusts to the distance of objects by changing its thickness
What is the lens
What is conductive deafness
What is the olfactory receptor
The process of sensation- input of sensory information from the external environment that is received by our sensory receptors
What is bottom-up processing
The process where we become more sensitive to weak stimuli and less sensitive to unchanging stimuli
What is sensory adaptation
The area where when light hits the point where the optic nerve leave the eye, registers nothing because the area lacks photoreceptors
What is the blind spot
The three bones that are found in the ear
The hammer, anvil and stirrup
Different types of information activate specific receptors that convert the stimulation of the skin to electrical nerve impulses
What is transduction
The way we interpret the information we have recieved
What is perception
The stimulation of our senses result from sources of energy
What is true
