PSY 101 SDSU LAUMAKIS ACTUAL EXAM PAPER
2026 QUESTIONS WITH SOLUTIONS GRADED
A+
◉ 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.
◉ Blind Spot . Answer: the location where the optic nerve exists the
retina.
