Multiple determinants of behavior. -- Not all behavior is determined by the basic needs. We might even say that not all behavior is motivated. There are many determinants of behavior other than motives.[9] For instance, one other im-[p. 391]portant class of determinants is the so-called 'field' determinants. Theoretically, at least, behavior may be determined completely by the field, or even by specific isolated external stimuli, as in association of ideas, or certain conditioned reflexes. If in response to the stimulus word 'table' I immediately perceive a memory image of a table, this response certainly has nothing to do with my basic needs.
