100% Correct Answers (Verified) Latest Update
Grade A+
QUESTIONS AND ANSWERS
Sensation. ANSWER - the process by which sensory organs in the eyes, ears, nose, mouth,
skin and other tissues receive and detect stimuli.
Perception. ANSWER - the organization and interpretation of sensory stimuli by the brain.
Transduction. ANSWER - the process of transforming stimuli into neural signals.
Data-Based Processing. ANSWER - taking basic sensory information about incoming
stimuli and processing it for further interpretation.
Knowledge-Based Processing. ANSWER - drawing on past experiences and knowledge to
understand and interpret sensory information.
Absolute Threshold. ANSWER - the weakest stimuli that can be detected 50% of the time.
Sensory Adaptation. ANSWER - sensory receptors tend to become less sensitive to
constant stimuli.
Difference Threshold. ANSWER - the minimum difference between two stimuli that can be
noticed 50% of the time.
Weber's Law. ANSWER - the law stating that each of the five senses has its own constant
ratio determining difference thresholds.
Signal Detection Theory. ANSWER - a theory explaining how various factors influence
our ability to detect weak signals in the environment.
, Wavelength. ANSWER - the distance between wave peaks.
Hue. ANSWER - the color of an object, determined by the wavelength of light it reflects.
Amplitude. ANSWER - the height of a wave; the distance from midpoint to peak, or from
midpoint to the trough of a wave.
Saturation. ANSWER - color purity.
Cornea. ANSWER - the clear, outer layer of the eye that shields it from damage and
focuses incoming light waves.
Iris. ANSWER - the muscle responsible for changing the size of the pupil.
Accommodation. ANSWER - the process by which the lens changes shape in order to focus
on images near and far.
Retina. ANSWER - the layer of the eye that contain photoreceptor cells and the location
for the transduction of light energy into neural activity.
Photoreceptors. ANSWER - cells that absorb light energy and turn into chemical and
electrical signals for the brain to process.
Rods. ANSWER - specialized light receptors in the retina that are responsible for sight
when the light level is low; not sensitive to color, but useful for night vision.
Cones. ANSWER - specialized light receptors responsible for our sensation of color and
our ability to sense details.
Optic Nerve. ANSWER - the bundle of axons from ganglion cells leading to the visual
cortex.
