Sensory Adaption Our diminishing sensitivity to an unchanging stimulus Although, sensory adaption reduces our sensitivity, it offers an important benefit: It enables us to focus on informative changes in our environment without being distracted by the uninformative constant stimulation of garments, odors, and street noise.

Sensory Adaption…con’d Our sensitivity to changing stimulation helps explain television’s attention getting power. All the senses receive sensory stimulation, transform it into neural information, and deliver that information to the brain.

Vision Part of our genius is our body’s ability to convert one sort of energy to another. Sensory transduction is a process by which our sensory systems encode stimulus energy as neural messages. Your eyes transduce (transform) the energy into neural messages that the brain then processes into what you consciously see.

The Stimulus Input: Light Energy What strikes our eyes is not color but pulses of electromagnetic energy that our visual system perceives as color Two physical characteristics of light help determine our sensory experience of them: Light’s wavelength- the distance from one wave peak to the next- determines its hue ( the color we experience, such as blue or green). Intensity, the amount of energy in the light waves ( determined by a wave’s amplitude, or height), influences brightness.
