Thinking About Becoming A Psychology Student?
Optical illusions have long been a source of psychological interest, particularly in relation to visual perception, sensory processes and attention. The following extract, for instance, from 1897 is taken from an article written by E.W Scripture from Yale University entitled "Sources of The New Psychology."
"The physiology of the eye originated much of the psychology of sight. Concerning the functions of the optical systen, physiology can scarcely be said to have gone beyond the dioptrics of the eye. Nearly all further knowledge consists of deductions from the mental experiences of the subject. For example, physiology knows almost nothing concerning the functions of the retina. Psychologically, however, the color sensations and their combinations can be accurately measured. It is trus that the investigations of color vision have been are mainly carried out by physiologists and physicists; but the point of view has become primarily a purely psychological one. This is strikingly exemplified in the researches of König, from which physiological deductions and practically excluded. For the various other phenomena, such as those of the optical illusions, of monocular and of binocular space, we have at present no hope of anything beyond a psychological knowledge, and the investigations of Hering, Helmholtz, and others can be regarded as direct contributions to psychology."
