Basic Concepts
Constructs perceptions from this sensory input by drawing on your experience and expectations.
i.e. object --> What it means
What is top-down processing?
Round opening in the center of the iris that changes size to let light into the eye
What is the pupil?
The debate of yanny/laurel is an example of...
Name the sense: A chemical sense in which the molecules of a substance carried in the air reach a tiny cluster of receptor cells at the top of
each nasal cavity.
What is smell/olfactory?
The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.
What is sensation?
Retinal receptors that detect black, white, and gray, and are sensitive to movement.
What are rods?
Which determines the pitch of a sound: amplitude or wavelength
What is wavelength?
What does amplitude determine?
Name the sense: Your body’s way of telling you something has gone wrong.
What is pain?
The process of organizing and interpreting sensory information, enabling us to recognize meaningful object and events.
What is perception?
Name the part of the eye: The light-sensitive inner surface of the eye containing the receptor rods and cones plus layers of neurons that begin the processing of visual information.
What is the retina?
Part of ear that houses the cochlea, semi-circular canals, vestibular sacs.
What is the inner ear?
What are smell and vision?
The minimum stimulus energy to detect a particular stimulus 50% of the time.
ex. being able to see a candle from 30 feet away
What is the absolute threshold?
Processing many aspects of a problem simultaneously.
What is parallel processing?
Name for the outer ear (hint: it's not the lobe)
What is the pinna?
Pressure, warmth, cold, pain
Diminished sensitivity because of constant stimulation. Becoming used to the sensory input.
What is sensory adaptation?
The central focal point in the retina around which the eye’s cones cluster.
What is the fovea?
Name one of the three bones in the middle ear.
Malleus, Incus, and Stapes
System for sensing the position and
movement of individual body parts.
What is kinesthesia?
