simple: push the button when the light comes on
choice: push 1 button when the light is on the left side, a different one if light is on right side
How would Donders find the length of time the decision takes?
subtract the simple RT from choice RT
How long does it take to make a decision on average?
0.1 seconds
What did Ebbinghaus study?
was interested in learning and memory, would read a list of made-up words to see how many repetitions it would take to not make a mistake
How many repetitions are required for short break intervals?
fewer repititions
What are savings?
reduction in repititions needed to relearn the list after break
=original time to learn list - the time to relearn list
What does a savings curve look like?
savings decreases rapidly until around 2 days, plateaus after, not much change after 6 days
What did Wundt do?

used introspection, taught first psyc at harvard, wrote principles of psychology
What issues did Watson see with introspection? What did he propose?
variable results per person and difficult to verify
behaviourism
