Document Summary
Synesthesia sensory response is different to what is stimulated. *there is a theory that we are born this way and our brains develop (pruning) The basket ball test selective attention: attention is finite, when you are completely focused on one thing you may not notice another. Sensation: the act of using our sensory systems to detect environmental stimuli. Sensory receptor cells - specialized cells that convert a specific form of environmental stimuli into neural impulses. Sensory transduction the process of converting a specific form of sensory data into a neural impulse that our brains can read. The limits of the senses: threshold: absolute threshold the minimal stimulus necessary for detection by an individual, difference threshold/ just noticeable difference (jnd) the minimal change in a stimulus that can just barely be detected. Weber"s law the jnd of a stimulus is a constant proportion despite variations in intensity.
