Document Summary
In order to survive, organisms need to know the world around them. The primary function of our sense organs is to provide information that can guide behaviour. The way this information is transmitted and processed, influences the way we perceive, interpret, and think about, the world around us. Key to survival that the brain processes it, so we can respond. Sensation the detection of simple properties of stimuli (without making sense of them, ex: no perception or interpretation) not making sense of things. Distal stimulus the stimulus in the environment, the things out there (i am a distal stimulus to you). Proximal stimulus the stimulus as it is stimulating our sense receptors (the. Image of me that is being projected onto the back of your retina, and the sound waves that are vibrating your auditory hair cells are the proximal stimuli). Perception the detection of more complex properties of stimuli (i. e. it"s meaning) this involves learning.
