How much of our behavior is a consequence of our unique and special qualities, the individual differences that differentiate us from other people?

“…how much of our behavior is a consequence of our unique and special qualities, the individual differences that differentiate us from other people?  Conversely, how much reflects the culture and society in which we live, stemming from universal principles that underlie the behavior of all humans?  Psychologists who rely on the neuroscience perspective tend to look for universal principles of behavior, such as how the nervous system operates or the way certain hormones automatically prime us for sexual activity.  Such psychologists concentrate on the similarities in our behavioral destinies despite vast differences in our upbringing.  In contrast, psychologists who employ the humanistic perspective focus more on the uniqueness of every individual.  They consider every person’s behavior a reflection of distinct and special individual qualities.”
