PSY 101 SDSU LAUMAKIS TEST 2 QUESTIONS
AND ANSWERS 100% CORRECT |ALREADY
GRADED A+
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.
Blind Spot - Answer-the location where the optic nerve exists the retina.
Feature Detectors - Answer-neurons in the visual cortex specialized in
detecting specific features of the visual experience, such as angles, lines,
and movements.
Dark Adaptation - Answer-ability of the eyes to adjust to dark after
exposure to brightness.
Light Adaptation - Answer-ability of the eyes to adjust to light after
being in the dark.
Trichromatic Theory - Answer-the perception of color is the result of
three types of cones, each sensitive to particular wavelength in the red,
green, and blue spectrums.
, Afterimage - Answer-an image that appears to linger in the visual field
after its stimulus, or source, is removed.
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.
