PSYA01H3 Lecture Notes - Lecture 19: Radiant Energy, Sensory System, Absolute Threshold
Document Summary
Remember weber; he tried to learn the internal state of people. Slide 2: you listen and interpret, but the mind uses previous knowledge to predict what"s about to be said next. Google perceptual illusion to see some weird stuff that can trick your visual perception. Slide 3: you can see things fine, but you may not recognize what the meaning is. Perception- a recognition of what you see/hear etc. Slide 4: transduction- a process that changes a physical stimulus from the external world, translates it and sends it to the neural impulse. It depends on what energy the sensors are sensible to (receptor cells; they react to that energy) Table 5. 1- sensory systems and what energy they"re sensitive to. Some are chemical that need to directly touch you, while others (like radiant energy) can reach you from a long distance. We need to realize how limited our sensory systems are (ex.
