Document Summary
Plato: nativism: our perceptions are not derived from external sources (senses). We have innate abilities: perception depends on events and energy that change in the world, our understanding of reality is restricted to what we can perceive. Heraclitus: we can never perceive the exact same thing more than once in the world b/c the first time we experience it changes how we experience it the second time; everything flows. Adaptation: when we get used to something b/c it"s been there for a while. Democritus: we sense things b/c atoms from objects bounce off to interact with atoms in our organs. Perception is the physical interaction b/w the world and our bodies. Sensory transducer: a receptor that changes physical signals form the environment into neural signals that the brain can interpret (for every sense ) Hobbes: everything we know and imagine is learned through senses; only matter exists. Fechner: known as the father of experimental psychology .
