This paper presents an explanation of some laws of perception with regard to S–R principles of learning psychology. The possibility of connecting two great schools in the science of psychology − behaviorism and gestalt psychology – which are often presented as opposites, is demonstrated and, by this is also described an analogous model of Gestalt theory within behavioral principles, providing insight into the partial equivalence of the two theories, where the essence of the analogy is the claim of the existence of identical or very similar explanations in the two theories, only with different formulated constructs. The authors prove that these are different terms, and the same or similar concepts: what are sensations and perceptions in gestalt psychology, are molecular and molar stimuli in behaviorist psychology. A set or assembly of smaller, elementary (molecular) stimuli gives a molar stimulus that causes the evocation of the main perceptual reaction, which is analogous to the law of formation of stimuli in observations in Gestalt psychology. Authors demonstrate the explanatory potential of behavioral theories in the field of music, i.e. the phenomenon of melody transposition, the famous argument of gestaltists. An important construct in the work is external inhibition, as well as intervals - interruptions, spaces - between stimuli, because they also represent stimuli that participate in the construction of the whole, ie. there is no empty space − and empty space is a kind of stimulus.
