QUESTIONS AND CORRECT DETAILED
ANSWERS FROM A VERIFIED SOURCE
|ALREADY GRADED A+
Sensation - CORRECT ANSWER-the process by which sensory organs
in the eyes, ears, nose, mouth, skin and other tissues receive and
detect stimuli.
Perception - CORRECT ANSWER-the organization and interpretation
of sensory stimuli by the brain.
Transduction - CORRECT ANSWER-the process of transforming
stimuli into neural signals.
Data-Based Processing - CORRECT ANSWER-taking basic sensory
information about incoming stimuli and processing it for further
interpretation.
,Knowledge-Based Processing - CORRECT ANSWER-drawing on past
experiences and knowledge to understand and interpret sensory
information.
Absolute Threshold - CORRECT ANSWER-the weakest stimuli that
can be detected 50% of the time.
Sensory Adaptation - CORRECT ANSWER-sensory receptors tend to
become less sensitive to constant stimuli.
Difference Threshold - CORRECT ANSWER-the minimum difference
between two stimuli that can be noticed 50% of the time.
Weber's Law - CORRECT ANSWER-the law stating that each of the
five senses has its own constant ratio determining difference
thresholds.
Signal Detection Theory - CORRECT ANSWER-a theory explaining
how various factors influence our ability to detect weak signals in the
environment.
Wavelength - CORRECT ANSWER-the distance between wave peaks.
, Hue - CORRECT ANSWER-the color of an object, determined by the
wavelength of light it reflects.
Amplitude - CORRECT ANSWER-the height of a wave; the distance
from midpoint to peak, or from midpoint to the trough of a wave.
Saturation - CORRECT ANSWER-color purity.
Cornea - CORRECT ANSWER-the clear, outer layer of the eye that
shields it from damage and focuses incoming light waves.
Iris - CORRECT ANSWER-the muscle responsible for changing the
size of the pupil.
Accommodation - CORRECT ANSWER-the process by which the lens
changes shape in order to focus on images near and far.
Retina - CORRECT ANSWER-the layer of the eye that contain
photoreceptor cells and the location for the transduction of light
energy into neural activity.
Photoreceptors - CORRECT ANSWER-cells that absorb light energy
and turn into chemical and electrical signals for the brain to process.
