1. CEP 909 - Remember? September 15, 2005

2. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Is learning about cognition like this?

3. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Information Processing Model

4. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Perception  Really cool  Not going to deal with it

5. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Attention  Really cool  Not going to deal with it

6. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Motor Control  Really cool  Not going to deal with it

7. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  Seems to be Limited Capacity  7 +/- 2 items - Miller  Increasing storage is done by increasing the size of an item - called chunking.  E.g. “2 2 4 0” vs. “5 seconds faster than my best 5k (22min, 45 secs)”  Confirmed by your results?

8. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term or Working Memory  What can you tell me about it, based upon your (meaning your personal and your classmates’) experiments this week?

9. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  Seems to be Modal  Roughly corresponding to the sensory stores  Auditory - Articulatory Loop  Visual - Spatial Sketchpad (Baddley, etc.)  Others?

10. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  Seems to be serial (sequential)  Example: tell people to recall as many of the following as possible: “Quick, 12, Love, hungry, Orange, Blue, Desk, 45.3”.  Was “12 in the list?”  Was 45.3 in the list?  The further in the list it is, the longer it takes to answer

11. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  Requires “effort” to get information to Long-Term Storage  Rehersal  Processing  Attention  Mnemonic  Etc.  Distractor tasks are often used to prevent long-term memory formation

12. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  It’s fast  100 ms on average to retrieve an item

13. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Short-Term Memory aka Working Memory  It is not one-way from perception to working memory  E.g. couple, lovers, space, brown, dating

14. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Your homework due today  For each item in the list, we’re going to aggregate our data.

15. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Lets form some groups  My plan is to give you a few minutes to let you form your own groups. (3 or 4 people)  Combine that with the break  If all goes well, I do not have to help you make groups.  See you in 20 minutes.

16. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Group Assignment

17. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Your homework  I will provide feedback for both your homework assignments so far by Monday.  After that we will grade for real.

18. Matthew J. Koehler September 15, 2005CEP 909 - Cognition and Technology Next Week  Lets review what’s due for next week
