![]() We also use other cues according to Gibson’s direct theory of perception. When we look around we do not see blocks of colours but instead, we see different textures, patterns of shade, mixtures of tones or smoothness to inform us what they are like. ![]() To clarify – Motion Parallax is the way in which our visual field changes with movement with close objects seeming to move more than objects which are far away. Gibson’s Direct Theory of Perception is the idea that we perceive simply by using the information we receive through our senses and this is enough information for us to make sense of the world around us. He proposed people, as well as animals, do not receive simply passive images about the world around them but they are active within it and this activity changes the visual images we receive.Īn example of this is when we are in motion and moving along a road the visual image we receive changes as things closer to us appear to be moving much faster as we go past them while things that are further away appear to move slower or not very much. This effect is known as motion parallax and happens only if we move and it combines depth cues to help us accurately judge distances. Psychologist James Gibson proposed his direct theory of how perception works. To have greater accuracy, other depth cues rely on the usage of two eyes as this involves comparing the slight differences in images that each eye receives. This is referred to as binocular depth cues. We, however, live in a three-dimensional world where we must also consider depth and distance to avoid bumping into things or being hit by moving traffic. To do this we need to know how far things are and judging this distance is something we do automatically using information known as depth cues.ĭepth cues tell us about the third dimension of our world, specifically, the depth or distance and this aids us in survival as it tells us how far or near something is from us. Depth cues are visible in pictures despite them being two dimensional and based on height and width. Pictures instead use a set of cues known as monocular depth cues as we can use them even if we are looking with only one eye. These monocular depth cues tell us how far things are but this is not completely accurate. Our eyes receive an image that is two dimensional similar to a picture. Gregory’s constructivist theory of perception (the role of nurture).Gibson’s direct theory of perception (and the influence of nature).The two main theories that attempt to explain how perception works which we will explore in this chapter are: Or is perception a top-down process where our mind generates expectations of what we are looking at, and it is these expectations that then help us make sense of the information our eyes receive?. ![]() ![]() Is perception a bottom-up process whereby our perception is based solely on the information received by our eyes?.What this shows us is that our visual system has a tendency to organise information so we see patterns. This then raises important questions as to how our visual system actually works: Some people can make out the outline of a dalmatian walking along. This is quite strange considering there is no actual outline of the dog in the picture. Take a look at the picture above – What can you see in this collection of dots and blobs? ![]()
