The Behavior of Organisms

You may remember Skinner as the dude who put rats and pigeons and babies in boxes and conditioned them to perform certain behaviors.

Right around when Freud escaped to England, Skinner published his Behavior of Organisms, ushering in the era of behaviorism, which remained all the rage well into the 1960s.

The other major force at the time was, of course, Freud's psychoanalysis, and its many descendants, collectively known as the psychodynamic theories.

These focused on the importance of early experiences in shaping the unconsciousness, and how that process affects our thoughts, feelings, behaviors, and personalities.
