Document Summary
Nature vs nurture and how we come to experience our worlds. Detection means mechanical process eye will receive and detect it. Process that take us from sensation to perception---- transduction- taking detection and recording it in electrical signals that the brain will understand. That experience is going to subject to past experiences, mood/emotions, and expectations or thoughts. You keep addi(cid:374)g u(cid:374)til you say (cid:862) alty. (cid:863) -> absolute threshold. Signal detection theory: moving beyond simple thresholds: dilemma: the problem. If you take any individual and you ask if they see something when showing them light, they"ll (cid:271)e i(cid:374)(cid:272)o(cid:374)siste(cid:374)t e(cid:448)e(cid:374) though the light is the sa(cid:373)e ea(cid:272)h ti(cid:373)e. Sensory adaptation: sensory adaptation: get used to sensory information, ex: as info is being sent, firing slows down, ex: jumping into a cold body of water, stimuli firing (cold! Cold!) consistent stimuli -> firing slows down because its consistent.
