Short-term memory seems to be able to consolidate a sequence of ideas or pictures and produce one concept from them. Or to take a number of letters and produce the word. 

In reverse it can split up a concept into its component basic ideas - pictures - letters etc.

Output processor executes sequence of input & outputs - no thinking actions. Execution interrupted when main processor acquires use of input or output devices being used. ie. stops thinking (19th Sept) or incorrect input received by output processor. Start execution every time output done i.e. every call to MOTOR. – ASREW = “Y” i.e. associated input of reward.

Listening – speech: speaks produces sound – should interrupt attention but at what level? Sound produced by external world.

Sight – movement: moves produces change in sight. Sights produced by external world.

Also need a reaction for punishment.

Interest – drive: difference or novelty/new experience produce interest drive.

Nearly all (most) actions performed are not punished but can be done. Only after a long period, as action become more complex are constraints applied.

Imitation, brain asks for associated output and none there, so it imitates input as output.

A question results from no associated whatever being recalled.

The mind sets up a goal and associated pleasure to be activated when goal found. Then goes about purposeful search to acquire (reach) the goal.

What about slight physical movements paralleling thoughts?

Pay attention can actually be doing something = moving eyes.

Executing  at level of concentration

Idle at lowest level of concentration

Interrupt of execution by outside or memory causes reflex attention.

Executing sequence of attention payings or outputtings.

Instruction set is :

Pay attention to different receptors -> result -> memory

Pay attention to different recalls -> result -> memory

Output to different motors <- from memory

I have come to the firm belief that all possible outputs are available at birth or sometime shortly thereafter (as soon as muscles develop). And these outputs are learnt to be controlled - combined in unique sequences to obtain observed output. That is, primitive outputs are all available and able to be initiated by reflex, imitation or other means.

Comments made while at IJCAI-77.

- When executing will input a concept which was punished less than the concentration level. - I think I meant here that if a concept is recalled, provided it has an association strength of punishment then it should interrupt the execution process no matter what the level of concentration is.

- Recognition of similarity - important in applying old strategies to new situations. Short term memory produce - store the things to be recognized, both old and new situation generate the same concept - idea, that which is generated is obtained by paying attention to only a subset of the data at hand, i.e. subset of situations matches.

25th Sept 1977

I can recall seeing a sequence of sights ==> can actually do recall and look at the associated output and input.

26th Sept. 1977

I thought about an automatic (unconscious) motor system running in parallel to conscious system. "start unconscious when REFREW: RWD come back to conscious If conscious use listen or motor. Also come back to conscious.

27th Sept 1977

Need to refine short term memory functions. Similarity of last one is reflexive attention. When done, pay attention to last one – what ones? Input I, Output O, Ideas I = J Ideas O = P, Concept I = K, Concept O = Q

For short-term memory, search most recent 7 inputs for similarity. If so record similarity and recall, set interrupt level low on attention scale.
