Document Summary
Process from sensation to perception (3 basic principles) Sensation is the process by which the sensory organs collect information from the brain environment and transmit it to the brain (sensation comes first, like gathering jigsaw puzzle) Perception is the process by which the brain consolidates and interprets this information (perception comes second, putting all the pieces together) More about speed less about accuracy / brain aims to visualise shapes. There is no one-to-one comparision between the physical reality and psychological reality (e. g eyewitnesses testimonies) Sensation and perception are active, not passive (actively aware of engaging in process / focusing) The process from sensation to perception is adaptive (evolutionary concept) Sensation (common features among our senses; ears, touch, eyes, taste) The process by which our sensory systems translate physical stimuli into signals that we can understand. Info coming from environment (energy, sound waves, light) transform into electromagnetic energy that we can make sense of.
