1 How Do We Construct the Outside World? Sensation – detecting physical energy from the environment and encoding it as neural signalsPerception – the process of selecting, organising and interpreting sensory information, enabling us to recognize meaningful objects and events.SENSATION PERCEPTION = MEANING
2 Selective AttentionAt any moment, our awareness focuses (like a flashlight beam in the dark) on a limited aspect of all that we experience.Some researchers believe that ever second our five senses take in 11,000,000 bits of information (while we are conscious of 40 of them)
3 Inattentional Blindness Failing to see visible objects when our attention is directed elsewhere
4 Psychology and Optical Illusions Psychologists LOVE visual illusions, because they reflect visions preeminence among our sensesFun Fact: When vision competes with one of our other senses vision usually wins (this is called visual capture)
5 Perceptual Consistency Perceiving objects as unchanging (e.g., having consistent lightness, colour, shape, and size) even as illumination and retinal images change
10 Shape ConstanciesEbbinghaus Illusion - In the best-known version of the illusion, two circles of identical size are placed near to each other and one is surrounded by large circles while the other is surrounded by small circles; the first central circle then appears smaller than the second central circle.
