Priming occurs when a n earlier stimuli influences later stimuli. Habituation: is the tendency of the brain to stop attending to constant, unchanging info. Sensory adaptation: is the tendency of sensory receptors to become less responsive to a stimulus that is unchanging. Difference hab ignores and sen less responsive: vision: transduction: the transformation of stimulus energy into neural impulses. Photo transduction: wavelength: distance bt wave peaks(color). What does each allow us to be able to sense and perceive: o brightness, color, saturation, what are the structures of the eye, cornea: transparent tissue where light enters. Iris: muscle that expands and contract to change size of opening (pupil). Lens: focuses the light on retina with visual accommodation. Bipolar cells to ganglion cells to carry signals: nearsighted: nearby objects seen clearly.
