Document Summary

The development of sensory and perception systems can be a constraint or rate limiter if one is not functioning properly or if its development lags. Perception: sensation is the neural activity triggered by a stimulus activating a sensory receptor. With perception, we have to select relevant info. We then have to process the info and decide if we need to carry out a movement. Perception is a multistage process in the cns: selection, processing, organization, integration if we are denied senses from one system, we rely on other senses. Sensory systems function as individual structural constraints: visual, auditory, kinesthetic senses. Disabilities in sensory systems such as blindness can make us move slower. Blind infants won"t be able to reach and grasp. Blind infants would experience their environment through touch and explore it with their hands. If someone was deaf, they would not be able to tell which direction the sound was coming from.
