Memory and Forgetting
1.	Philosophical doctrine of association--that elements of thought are interconnected by simple rules of connection.
2.	Secondary laws of learning (Brown, 1820)
	a.	Served as the basis for experimental science.
	b.	The laws were the amount of practice and recency
3.	Experimental study of memory
	a.	Hermann Ebbinghaus earned a Ph.D. on the philosophy of unconscious (1873).
	b.	Invested seven years in independent study
	c.	Picked up a book and read about scientific psychology
	d.	He brought together the old philosophical problem of memory and the scientific method of psychology.
	e.	Ebbinghaus invented the nonsense syllable.
		1.	2 consonants and a vowel, at random
		2.	2,300 nonsense syllables are possible
		3.	The purpose was to control for previous learning (who had learned a consonant-vowel-consonant before?).
		4.	As was the practice at that time, he was the sole subject.
	f.	His epoch-making book was published in 1885. Memory depends upon:
		1.	Length of the material learned.
		2.	The effect of repetition
		3.	Forgetting as a function of time.
	g.	This was the first study of higher mental processes. Before this time it was thought that memory was too elusive and subtle to study experimentally.
4.	Demonstrations
	a.	Serial position effect including primacy and recency effects.
	b.	Highlighting
	c.	Meaningfulness on memory
