Document Summary
Perception: making of what the senses tell us. Sensory receptors (receive input) -> transduction -> analysis of stimulus features. > reconstruction into neural representation -> comparison with others -> recognition and interpretation. Absolute threshold: lowest level of detection 50% of the time. Lower absolute threshold (more sensitive); higher absolute threshold (less sensitive) Sensory adaptation: picking information relevant to remember. Light reflects and object, waves come into your eye, through pupil, to the retina. Rods and cones: neurones that change the waves. Back of eye, photoreceptor, bipolar ganglion, light waves. Cones can renew their intensity quicker than rods. Respond to specific characteristics of visual stimuli. Number of sound waves (cycles) per second. Ear drum -> oval window -> cochlea -> basilar and tectorial membrane -> hair cells in organ of corti -> neurotransmitters to auditory nerve. Nerve deafness receptor or auditory nerve issues. Takes place in the pores of your tongue. Sweet and fatty high calorie (good)
