To make the results of one's own introspection more reliable, it is best to give them to another competent person for examination. Here, psychologists from this field are best suited as they have many years of experience. But because, for obvious reasons, they are not often available, a professor of psychology must mainly rely on his students. However, one must make a careful choice, because many have little aptitude for introspection. Whereas one perhaps does not have the ability to analyze at all, because for him only the outside world is interesting, others are susceptible to self-deception.

Of the four circles on the right, each pair lying on a diagonal easily form one unit and the space between them becomes prominent. If we voluntarily bring two circles which lie on one side of the imaginary square to join into one unit, it becomes clear immediately that both complexes are exactly congruent. Further if we draw a cross from simple lines, with arms 'Of equal length, on the one hand lying and on the other hand standing, an immediate difference is shown in the interpretation (Fig. 17).

In addition to the lo~ger side of an oblong becoming more prominent, something else often occurs: we often traverse these sides with our attention so that its parts become successively prominent. Of course, my glance crosses the one or the other side of the square, but in doing this, the single parts in general do not stand out successively-assuming that the square does not exceed a certain size. The line in question is really caught as a whole by attention and is as a whole clearly before me. In such a ca~e~ one indeed talks of attention wandering, but It IS really only a wandering of the fixation point.
