Pick up questions for video: Brain Games. Complete #1 . Sensation & Perception. Sensation and perception are areas that have been of interest to psychologists for most of the history of psychology. As we sit here, our senses receive literally thousands of messages. We need to make sense of this information. Our senses take in the information, and they do so from birth. Yet the interpretive part -perception- requires knowledge.. Perceptual constancy. Stimuli changes, object perceived to stay the same. In other words:. Image on retina . changes. , but brain perceives image as being constant/unchanging . Stimuli changes, but . Introduction. Sensation =. . stimulation of sense organs. .

Analyze how color can be used to create moods and illusions. Explain how primary colors are used to produce other colors on the color wheel. Describe the effects of intensity and value on various hues. Eric King. Humans perceive color when light enters the eye and is detected by the photoreceptors, called cones, which are mainly located in the fovea. We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light, namely short (blue), medium (green), and long (red). How we perceive color also depends on how dim or bright the light is. . Introduction. Sensation.
