What is learning? How would you define it?
Are there different types of learning?
How do you learn new facts? New skills? Is all knowledge due to a
conscious processes, or is some knowledge acquired by unconscious processes?
Brainstorm…

Implicit Learning Passive process People acquire knowledge of new
information through exposure. Evolve outside of awareness, and cannot be consciously recalled, but causes changes in behavior.
“Muscle Memory”
Discuss: What have you learned using Implicit Learning?
H.M. and Implicit Learning H.M. is a famous patient
who had part of his brain removed and was no longer able to form new memories.
When performing tasks, such as mirror tracing, he was able to improve over time.
This result shows that he was capable of some types of implicit learning or “motor memory”
Explicit Learning Active process People seek out the structure of any information
that is presented to them. “Declarative Memory” -- one can talk about the
details of explicit memories and discuss them as fact
“Explicit learning is a more conscious operation where the individual makes and tests hypotheses in a search for structure” (Nick C. Ellis)
Discuss: What have you learned using Explicit Learning?

Explicit & Implicit Memory Tests
Look at the following words. This will test your memory for these words in various ways.
SPONGE CANDY DOLPHIN
PACKAGE POSTER LICORICE
ZEBRA SECTION CAMOFLAGE
MISTAKE PORTAL KNAPSACK
COFFEE QUAIL ALPINE
HANDLE PANTRY CARPET
EAGER CELLO PRESSURE
LLAMA ORIOLE ACRID
Memory Test
Explicit test of memory: recall
Write down the words you remember from the list in the earlier slide
Implicit test of memory: word fragment completion
On the next slide, you will see some words missing letters, some “word fragments” and some anagrams. Guess what each word might be.

Implicit Memory Tasks
Word-fragment completion is an implicit memory task.Fragments are (often) completed with words previously studied in the absence of an explicit instruction to remember the word
Amnesiacs often showed spared implicit memory
dissociation suggest different systems for implicit and explicit memory systems
Implicit vs. Explicit Memory Graf, Squire, & Mandler (1984):
Study words: cheese, house, …
Explicit memory test: cued recall. Complete fragment to a word from study list:ch _ _ _ _
Implicit memory test: word stem completion. Complete fragment to form any word: ch _ _ _ _
Bean Bag Toss ExperimentObjective To investigate and quantify different types
of learning (implicit and explicit) in the context of a bean-bag toss game using Fresnel prism goggles.
Hypotheses ???
Post “Bean Bag Toss” Debriefing: Which trial used implicit learning? Why? Which trial used explicit learning? Why? Which type of learning is easier? Why? Can explicit and implicit learning be separated
or are they interdependent with one being more prevalent that the other depending of the learning context?
Does explicit learning lead to implicit knowledge?
Debrief Learning is a relatively permanent change in
behavior that marks an increase in knowledge, skills, or understanding thanks to recorded memories.
Human memory is fundamentally associative. It is easier to remember new information if it is associated with previously acquired knowledge that is already firmly anchored in memory. The more meaningful the association, the more effectively it will help remember.
Extension: Tower of Hanoi The objective of the puzzle is to move
the entire stack to another rod, obeying the following rules: Only one disk may be moved at a time. Each move consists of taking the upper
disk from one of the rods and sliding it onto another rod, on top of the other disks that may already be present on that rod.
No disk may be placed on top of a smaller disk. http://en.wikipedia.org/wiki/File:Tower_of_Hanoi_4.gif
