The Gestalt psychologists believed that much of perception is shaped by innate factors built into the brain. In this chapter we will discuss the strengths and limitations of these capacities, focusing on both sensation—awareness resulting from the stimulation of a sense organ, and perception—the organization and interpretation of sensations. Perception is the selection, organization, and interpretation of sensory input.

Transformation of one form of energy into another--especially the transformation of stimulus information into nerve signals by the sense organs. The photoreceptors are as far as light gets into the visual system. determines brightness, determines how much light gets in the eye by controlling the size of the pupil, through accommodation, light that enters the pupil is focused by it, as light passes through it, the image is flipped upside down and inverted, the focused inverted image projects on it, occurs when light activates neurons in the retina, cones- activated by color, clustered around the fovea, rods- peripheral vision, respond to black and white, outnumber cones, when enough cones and rods fire, they activate the next layer of bipolar cells, if enough bipolar cells fire, the next layer of ganglion cells is activated, the axons of it form the optic nerve that sends impulses to the LGN, impulses from the left side of each retina go to the left hemisphere of the brain, right right, optic chiasm- spot where the nerves cross each other, impulses travel from the retina to the visual cortex to them, visual perception is a combination of all features, these are activated in combinations to produce other colors, can’t explain afterimages or color blindness, the sensory receptors arranged in the retina come in pairs, when one sensor is stimulated, the other is inhibited from firing, created by vibrations which travel through the air, sound waves are collected in the pinna (outer ear), they reach the eardrum (tympanic membrane), a thin membrane that vibrates as sound waves hit it, connects with the hammer (malleus) which is connected to the anvil (incus) which connects to the stirrup (stapes), the ossicles transmit the vibrations to the oval window, attached to cochlea, which is shaped like a snail’s shell and filled with fluid, as the oval window vibrates, the fluid moves, hair cells on the basilar membrane (floor of cochlea) move, the hair cells are connected to the organ of corti (neurons activated by movement of hair cells), auditory nerve sends these impulses to the brain, hair cells in the cochlea respond to different frequencies of sound based on where they are located, better explains how we sense higher pitches, problem with the system of conducting the sound to the cochlea, in ear canal, eardrum, ossicles, or oval window, Some nerve endings respond to temperature, others to pressure, Our brain interprets the amount of indentation (temperature change) as intensity of touch, Nerve endings are very concentrated in the fingertips, Pain receptors will fire when other receptors are stimulated sharply, some pain messages have a higher priority, gate is open to it, and shut to lower priority messages, Chemicals from food are absorbed by taste buds, some taste buds respond more intensely to one, the more densely packed the taste buds, the more chemical absorbed → intense taste, molecules of substances rise into the air, gathers messages from the olfactory receptor cells, nerve fibers from it connect to the brain at the amygdale and hippocampus, Tells us about how our body is oriented in space, give brain feedback about body orientation, Gives us feedback about the position and orientation of specific body parts, The study of the interaction between the sensations we receive and our experience of them, the minimum amount of stimulus we can detect 50% of the time, Difference threshold (just noticeable difference), smallest amount of change needed in a stimulus before we detect a change, the change needed is proportional to the intensity of the original stimulus, Investigates the effects of the distractions and interference we experience while perceiving the world, Tries to predict what we’ll perceive among competing stimuli, also called receiver operating characteristics, we think we perceive a stimulus that isn’t there, not perceiving a stimulus that is present, We perceive by filling in gaps in what we sense with background knowledge, mental representations of how we expect the world to be, a predisposition to perceive something in a certain way, supposed hidden messages musicians played backwards in their music, Perception starts at the bottom with the individual characteristics of the image, Puts characteristics together into our final perception, We normally perceive objects as groups, not isolated elements. Perceptual analysis that emphasizes the perceiver's expectations, concept memories and other cognitive factors, rather than being driven by the characteristics of the stimulus.
