I think this is why people perceive different things when in the same visual circumstances.įace recognition is equally fascinating, particularly in young children, there has to be an innate process which has evolved to promote this.Figure 5.1 If you were standing in the midst of this street scene, you would be absorbing and processing numerous pieces of sensory input. Hi Dr Billy Kidd, thank you for reading and commenting, I am glad you enjoyed the article!Ĭertainly the side that really interests me is how visual information is translated in the brain and I do think our prior experiences and memories play a large part in how we understand this input.

Perception Magazine might be of some help to you if you already have not discovered it: Wonderful, thank you very much for the tip, I will definitely go and have a look - thanks again Dr Kidd!ĭr Billy Kidd from Sydney, Australia on December 28, 2014: PsychGeek (author) from UK on December 28, 2014: I've been in a design field for many years and have often been interested in how different my colleagues 'see' things and how 'non-designers' interpret design. I also find face recognition is equally fascinating. PsychGeek, that was very interesting - thank you for sharing. Graham Gifford from New Hamphire on December 31, 2014: I have been quite surprised at the differences in what people can see with illusions and how many people just don't 'see' them at all - I wonder whether more designers see them in general and if this is because they are tuned in to them, as it were, more so than non-designers? Really interesting ideas, thanks again! Hi alifeofdesign, thank you for reading and commenting, I am glad you found it interesting! I do think face recognition is going to be one of my next projects, it is certainly a fascinating area.

The fovea is an area that contains the highest density of cones and is responsible for perception of fine detail. Cones are responsible for our ability to detect fine detail and different colours and are the basis of our vision at higher (daylight) light levels.Ī significant area of retina is the macula and the fovea. Rods respond better to low light levels therefore they are the cells responsible for maintaining some vision in poor light. Our retina has two classes of receptor cells called rods and cones, both of which are sensitive to light.It is the receptor cells in the retina that translate the light into images.This light is focused by the lens and the cornea onto the retina, a light sensitive membrane on the back surface of the eye.The eye relies on light, which passes through the cornea., via Wikimedia Commons How the Eye Works By National Eye Institute, National Institutes of Health.
