1 How Do We Construct the Outside World? Sensation – detecting physical energy from the environment and encoding it as neural signals Perception – the process of selecting, organising and interpreting sensory information, enabling us to recognize meaningful objects and events. SENSATION PERCEPTION = MEANING

2 Selective Attention At 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 senses Fun 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
