Summary of the Little Albert Experiment

A

The 9-month-old boy was exposed to Stimuli and observed, but showed no fear. He was exposed to a white rat and showed no fear but when the rat was presented again and Watson hit a metal pipe with a hammer, Albert cried.

Q

Process of Memory

A
  1. Sensory Information from the External Environment enters Sensory Memory. If it is not attended to, it is lost from Memory
  2. If the Sensory Information is attended to, it gets transferred to Short-Term Memory where it gets rehearsed. It it is not rehearsed, it is lost from Short-Term Memory
  3. If the Sensory Information is rehearsed in Short-Term Memory, it gets encoded into Long-Term Memory where some information may be lost over time.
  4. If a person wants to retrieve the stored information, it gets brought from Long-Term Memory back into Short-Term Memory
