Perception
Senses
Potpourri
100
Any aspect of or change in the environment to which an organism responds
What is a stimulus
100
An ability to gain information by some means other than the ordinary senses
What is extrasensory perception (ESP)
100
the experience that comes from organizing bits and pieces of information into meaningful wholes
What is Gestalt
100
balance is regulated by which system
What is the vestibular system
100
useful for night vision and are not sensitive to color
What are rods
200
the principle that the larger or stronger a stimulus, the larger the change required for an observer to notice a difference
What is Weber's Law
200
the tendency to perceive certain object in the same way regardless of changing angle, distance or lighting
What is constancy
200
When there is a familiar object or shape that has missing parts we fill in the spaces
What is closure
200
the sense of movement and body position
What is kinesthesis
200
lesson the pain by shifting our attention away from the pain impulses (it is why athletes can finish a game injured)
What is Gate control theory of pain
300
The weakest amount of a stimulus that a person can detect half the time
What is an absolute threshold
300
the difference between the images stimulating each eye
What is retinal disparity
300
Grouping objects that are similar and close
What is proximity
300
known as the chemical senses becuase their receptors are sensitive to chemical molecules
What is the sense of smell and taste
300
taking information from the senses and organizing it into meaningful material
What is perception
400
responding to changes in the environment becuase our senses have the ability to adapt to a contant level of stimulation.
What is sensory adaptation
400
the innermost coating of the back of the eye, containing the light-sensitive receptor cells
What is the retina
400
Two binocular depth cues
What is Convergence - the process by which your eyes turn inward to look Retinal disparity - the differences between the images stimulating each eye
400
the pathway of sound (Describe)
What is 1)the outer ear receives the sound 2) earflap directs sound down the auditory canal 3)Vibrations occur in the canal and vibrate the eardrum 4)middle ear is filled with 3 tiny bones which vibrate and push against the cochlea- this bony tube contains fluids and neurons. 5)Pressure causes the liquied to move hairs that are attached to sensory cells that pick up the motion and turn into neuronal impulses. 6)The auditory nerve caries impulses to the brain (temporal lobe)
400
occurs when a stimulus activiates a receptor
What is sensation
500
Two types of processing stimuli
What is Preattentive - extracting information automatically Attentive - A procedure that considers only one part of the stimuli presented at a time.
500
the study of the relationships between sensory experiences and the physical stimuli that cause them
What is psychophysics
500
Three monocular depth cues that 1)farther away the less detail 2) overlappping of images 3)parallel lines convergewhen stretched into the distance
What is 1) texture-density gradient 2) interposition 3)linear perspective
500
This is how vision occurs
What is 1)light enters the eye through the pupil and reaches the lens 2)the lens focuses the light on the retina 3) the retina contains the receptors, rods and cones, which turn the light energy into neuronal impulses 4) these impulses travel over the optic nerve to the brain where it is routed to the occipital lobe
500
brief auditory or visual messages that are presented below the absolute threshold
What are subliminal messages
