One of the most important (and confused) subjects in the interlocking and overlapping fields of sociology and social psychology is the category of motivation. It is apparent that human movements are possible only when appropriate action-patterns exist and that these patterns must be either inherited or acquired. It is also apparent that the functioning of both human and non-human animals is largely motivated by action-patterns that seem to be products of germinal development. These patterns are present at birth or soon after, relatively stable and unmodifiable, common to the species, usually adaptive and largely unlearned. If they are relatively simple, like grasping, knee-jerking, winking, they are "reflexes"; if they are more complex like crying, suckling-swallowing, assimilating-excreting, manipulating, they are " instincts." Just how complex such responses must be to be " instincts " is undetermined and perhaps indeterminable. The safest procedure, probably, is to call them instinctive, innate, native, germinal, and let it go at that.On the other hand, it is equally obvious that most human cultural behavior is motivated by action-patterns acquired through social conditioning. It is his greater capacity for building new action-patterns that distinguishes the human animal from the non-human animal. Following Thorndike, it is customary to describe the innate type of behavior as original and the second type as acquired. Thus, while vocalizing is an original trait of man, speaking a language is an acquired trait; hunger, putting-objects-in-mouth-and-swallowing, is natural, but seeking specific foods is a culture-trait; sex activity is native, but particular love-making and marriage-family complexes are acquired action-patterns. The most significant human acquisitions are the action-patterns we call language, vocal symbolization, thinking, rt consciousness." These habits, like all other > action-patterns, are neuromuscular mechanisms. Thinking is acting; "consciousness " is movement of specific parts of the organism.
