People (and animals) do not just receive passiveimages of the world, it is a bottom up theory that has evolved in all animals to help bestinteract with their environment
Gibson thought our senses provide all the information we need to accurately make sense of the world, the potentialuses of objects (affordances) can be perceiveddirectly without relying on inferences or assumptions based on pastexperience
Complex information about light, texture and detail all comes from the environment, allowing accuratejudgements about features such as distance and movement
Gibson thought accurateperception is innate not learnt, coming about from evolution,animals with the best/mostaccurateperception had the bestevolutionaryadvantage
