Limited attention span
A fundamental feature of passive self-organizing memory where only a single coherent area of the memory surface can be activated at a time, based on current input, recent input, and past state. This leads to the selection of the most familiar pattern, which becomes ever more familiar, enabling processes like selection, rejection, combination, and separation.
THE IDEA
A fundamental feature of a passive self-organizing memory system is the limited attention span. This is why only one spoonful of water at a time was poured onto the jelly surface. The mechanics of how a passive memory surface can come to have a limited attention span are explained elsewhere. The limited attention span means that only part of the memory surface can be activated at any one time. Which part of the surface comes to be activated depends on what is being presented to the surface at the moment, what has been presented to the surface just before, and the state of the surface (ie. what has happened to the surface in the past).
This limited attention span is extremely important for it means that the activated area will be a single coherent area and this single coherent area will be found in the most easily activated part of the memory surface. (In the jelly model this would mean the deepest hollow.) The most easily activated area or pattern is the most familiar one, the one which has been encountered most often, the one which has left most trace on the memory surface. And because a familiar pattern tends to be used it becomes ever more familiar. In this way the mind builds up that stock of preset patterns which are the basis of code communication.
With the limited attention span the passive self-organizing memory surface also becomes a self-maximizing one. This means that the processes of selection, rejection, combination and separation all become possible. Together these processes give the mind a very powerful computing function.
When to use it
Designing educational curricula that introduce concepts one at a time, building gradually on familiar material.
Understanding why first impressions are so influential and how to counteract their bias in decision-making.
Explaining the persistence of stereotypes despite contradictory evidence (familiar patterns dominate attention).
Improving productivity by structuring work sessions to focus on a single task, reducing cognitive overload.
FROM THEORY TO EVERYDAY LIFE
In practice
Jelly model of memory
Imagine pouring a spoonful of water onto a jelly surface. Only one spot gets wet at a time, creating a single hollow. Repeated pouring at the same spot deepens that hollow, making it easier for water to collect there again. Limited attention focuses on the most familiar pattern, reinforcing it.
Everyday learning
When learning a new skill, you can only concentrate on one aspect at a time (e.g., finger placement on a piano). Repeated practice makes that pattern more familiar, so eventually you can combine it with others without conscious effort.
A MOMENT TO REFLECT
Put it to work.
Can you recall a situation where your limited attention span caused you to repeatedly focus on a familiar solution instead of exploring a novel alternative?
How might the self-maximizing nature of memory explain why strong habits are so difficult to break?
In what ways could you deliberately manage your limited attention span to build more useful mental patterns?
