Perception

Distance Perception

* how are we able to perceive how things are closer to us and further away

* Cues vs. Information

* Cues- hints or suggestions that are ambiguous on their own. you cant tell what things are with just the - cues. piece of the puzzle nothing specific. requires more elaborations

* Relative size can tell us relative distance

* Constuctivism - putting cues together to get the big picture

Information

* Global flow - can describe information -specifics - we can tell what the event is then we can generate

* Lawfully - like physics - Once the brain detects if then from the information - it can specify the event - it can tell us everything we need to know

* We can describe the input based on the environment

* Contrasted with cues because it is reliable and lawfully generated ( the brain evolves to detect it ) doesn’t need hits and cues.

* Fully informative ( very specific) everything the brain needed is on the stimulus fully specific ( that thing and only that thing) NOT simulative (flow of ratio across the eye

* Goal of the approach = no elaboration is required doesn’t need to calculate things and bring in memory instead it just needs the brain to detect

* Ecological approach - needs to be fundamental based on the brain needs to know everything must be reliable and rich type of information that requires no elaboration

Depth Cues

* Interposition - thing overlapping

Good continuation - will tell the brain what the continuation is when overlapping occurs

* Elevation - the ex: of trees whats higher or lower used to give brainw hats going on if its behind or in front

* Shading and lighting - we need a solid object but as it moves and has shadows we perceive depth and

* Relative size ( familiar or identical )

* Lens accommodation - the lends changing it shape - the muscles change so we have more cues for depth

This is muscular change KINESTHETIC we have sensors that...
