The boundaries between inheritance and environmental influences are probably not fixed. 12(a, c). It is likely that neurons responding to the same basic elements of an image, such as color or orientation of contours, are grouped together in the brain. Think about a triangle; it is composed of three lines or contours and three corners of different orientations. These lines, which excite different groups of cells, must be joined together before we can perceive the figure as a triangle. e. for our understanding of a visual image.

Even today we do not have good unifying alternatives to the dualistic concept, and this is a dilemma to anyone who wishes to ‘explain’ light. Modern theories combine the wave concept and the concept of photons, and we use either the particle or the wave analogy depending on which one best suits the phenomenon being dealt with. 1 shows light as a part of the spectrum of electromagnetic radiation. Light – or visible radiation – is the small ‘window’ in this spectrum that allows us to see with our eyes, as a small part of a much greater spectrum that consists of everything from radioactive radiation to radio waves.

After-impressions of illusory movement without actual displacement, such as when you look out of the window of a train that has just stopped at the station, is another example of paradoxical experiences (cf. Zenon’s paradox). 17, we learn that there is dissociation between ‘perception of movement’ and the actual ‘physical movement’. 10 (a) The Zo¨llner illusion. The long diagonal lines are all parallel, but seem to converge and diverge. (b) The stripes inside the disks are all horizontal, but appear tilted in a direction opposite to that of the surrounding stripes.
