My Sandbox

OK, nothing here YET. But stay posted!

Let's see if I can subdivide this sandbox!

My active imagination sends me here: My Active Imagination

Whereas, declarative learning would send me here: My Declarative Learning

But I'm more likely to be here: Psych rat group depression

Unless I'm just hanging out in the main part (here).

What I Might Add About Declarative Learning

Declarative learning is acquiring information that one can speak about. Contrast with motor learning. The capital of a state is a declarative piece of information, while knowing how to ride a bike is not. Episodic memory and semantic memory are a further division of declarative information.

There are two ways to learn a telephone number, memorize it using your Declarative Memory or punch it into your brain 1,000 times to create a habit. Habit learning is called striatal memory or striatum memory.

Declarative memory uses your Medial Temporal Lobe and you can recall the telephone number at will. Habit (Striatum) memory activates the telephone number only when you are at the phone and uses your right-hemisphere's skill Pattern Recognition.

• Might be redundant now?

Research indicates Declarative and Habit memory compete with each other during distraction. When in doubt the brain chooses Habit memory because it is automatic.

Google Proceedings of the National Academy of Sciences, 7.25.07 Russell A. Poldrack UCLA.

I think all this information came from the one paper. There are several references within that paper that can better document the information.

• Step 1- I'd like to describe the experiment a little better.

Poldrack and coworkers tested the hypothesis that distraction can change the way a task is learned. In their experiment, they played a series of high and low tones while asking subjects to do a simple probabilistic classification task. In the single task (ST) case, subjects only learned to predict the weather. In the dual task (DT) case, subjects were also asked to count the number of high pitched tones. The ability to use the learned knowledge was found to be about the same in either case. However, subjects were significantly better at identifying cue-associations (a test of declarative knowledge) when trained under ST rather than DT conditions. Furthermore, fMRI showed activity in the hippocampus was associated with performance under ST, but not DT conditions, whereas activity in the putamen showed the opposite correlation. The authors conclude that while distraction may not decrease the level of learning, it can result in a reduced ability to flexibly use that knowledge

• The above paragraph is now on the real page.

• Aha!

I found this paper:

Foerde, L., Knowlton, B.J., & Poldrack, R.A. (2006). Distraction modulates the engagement of competing memory systems. Proceedings of the National Academy of Sciences, 103, 11778-83.

And I have the article! So I can at least clean up this statement.

• And maybe a little more formatting-

• I added See Also, Further Reading and References also.

Complex Declarative Learning

Michelene T.H. Chi Stellan Ohlsson

A chapter that talks about complex knowledge being divided into declarative knowledge (knowledge of facts) and procedural knowledge (knowledge of how). They say they will talk about the basic characteristics of complex declarative knowledge and changes that occur in declarative knowledge as it is learned. Not sure if this is totally consistent with the current entry.

I believe declarative knowledge is also a Wiki entry- probably need a link.

Descriptive knowledge
