Sensing the WorldSenses make an organism adapted to its niche. We as human beings are sensitive to sound frequencies that represent the range of the human voice.Absolutethreshold- absolute minimum sensory information needed to sense somethingWeber’sLawdifference threshold gets bigger and bigger depending on the original stimuli.Sensing Stimulation and DifferencesSensoryadaptation: Diminished sensitivity as a consequence of constant stimulation.Put a band aid on your arm and after a while you don’t sense it.Sensing difference in stimulation depends on the starting level of the stimulation.VisionTransduction: in sensation, the formation of stimulus energy (sights, sounds, smells) into neural impulses. Wavelength: What determines our perception of color. Shorter: Violet. Longer: Red. Differenct wavelengths of light result in different perceived colors. Parts of the eye:1.cornea2.iris3.lens: Transparent structure behind the pupil that changes shape to focus images on the retina.4.retina: the light sensitive inner surface of the eye, containing receptor
