a mental iceberg. Leading to his idea of Ego, Superego,

empirically oriented psychologists.
Classical Conditioning

becomes a conditioned stimulus by being
repeatedly paired with an unconditioned
simulus, which naturally elicits an
unconditioned response.
Operant Conditioning

modified by consequences, which can either reinforce
the behaviour or punish it.
