Analysis of a context switch
Say, you are writing a letter. At one moment you hear the door bell. You get up, open the door, get the Amazon.com package from the postman, open it, smell the new book, put it away, and return to writing the letter. What happened here?
You were not actively tuning in to the auditive channel of information, so the doorbell was processed unconsciously. It is a trigger for a procedure of answering the door. Is there a process that tracks all input signals, and has a mapping of signal -> procudure trigger? Of course not. The procedures themselves know which signals to expect. But that would be strange as well. It would require that all procedures are all active at the same time, waiting for the next signal to come along. In this interpretation, all processes are state machines, "active" at the same time. Active, but dormant. Waiting for some signal. This is not impossible. But who is doing the interpretation from "high pitched noise" to "doorbell ringing"? Is it the door answering process, or some other process? It is the semantic interpretation of a phonological stimulus. Can it be done unconsciously? Do you first need to pay attention to the sound, to hear it's a doorbell, or do you first know it's the doorbell and then you pay attention? I think you first need to pay attention. So the sound is calling your attention. Is it just because it's a high pitched sound? No that doesn't matter. Your attention would be drawn as well if you your name was spoken out by someone.
I think it is not possible that the door opening procedure performs the semantic interpretation, because the level of processing is different. The procure consists of some high-level social steps, very different from the low-level step of phonological interpretation.
If the procedure itself would do the interpretation, it would follow that hearing the bell could be interpreted very differently as well, by some other procedure. Myself, I think that this is not possible. Unconscious processes mapping phonological signals to meaning are not context dependent.
Once the procedure answer door is activated by the signal door bell ringing, it changes to a different state: walk to door. This doesn't happen automatically, of course, as we are not a dog. The procedure sends a request for walking to the door to the CPU, or starts shouting at the director from the audience. If the director grants the procedure access, the procedure will now be the active context.
The active context is performed by default, and does not need to beg for attention each time something happens. So once we're walking to the door, we have paused writing the letter. Since this procedure was not finished, it will keep asking for attention until it gets it. So when the door is answered, and that task is done, the process of writing the letter will continue.
I said that the door answering process is active all the time. That's all nice, but can you actually say that there is a single door answering process? You can answer several doors at the same time can't you? Or write two letters at the same time. And each of these processes is different, has its own state. Sure, you cannot drive two cars at the same time, but that's more a physical constraint. You could drive two cars in a computer game for instance. Yes, you would need to switch context, but still, you would be executing several processes based on the same template (or frame), at the same time.
Now there a several ways in which different processes can be created based on the same template. By means of instantiation, or prototyping. Which one to choose? I think it is important here that the instance of the process creates feedback to the template, so if you learn something about the process while doing it, this will immediately influence the way the other process based on the same template is performed. So the process instance that is instantiated has a link to the template process and can change the template at any time.
Is there a single process waiting for the door bell all the time or not? Is the template process reacting to the signal? That's not possible, because it is abstract. I think there are no processes active if there's no need. I think a process gets instantiated when a trigger in the process template is matched as part of LTM associative memory. Process templates are stored in LTM, and so are all triggers that cause state transitions.
If one of these triggers is matched associatively, a process instance is instantiated, in a certain state. So, say, a friend suddenly throws you a ball. You will recognize the trigger as being part of the throw-and-catch procedure. So this process is instantiated. It is not just activated, because several instances of the same task may be active at the same time. Some other dude may throw you another ball, and then you are playing the game twice at the same time. You can do this, even if you have never played it with two persons before.
If the procedure is instantiated, it is important that it be destroyed as well, or the number of active processes just increases. Processes have terminal states. Once a process reaches one of these, the process is destroyed. All that is left of it are traces in episodic memory.

the right aquarium tank Bubblers
aquaria playset an actual cover to one fish's condition including the limit along with oxygen availability in really reduced tanks. therefore, it is required that every one choose to be built with tank bubblers, that assist the catch gently breathe quicker the moment put for the aquaria. anything else you need to replace its very own details working day offering freshwater. sizes and shapes all shapes and can be effortlessly produced from plastic as well clay. furthermore fish tank bubblers help out oxygen production, they function super employ and wining and dining towards the pet the fish and her or his sizes be located far more plus more,and dynamic. observe the tips not more than to know how to go about getting yourself one for your own personal.
Consider how big is the aquarium. The tank bubbler probably will not sit on almost all space residence container. specific saltwater fish species enthusiasts put the vivienne westwood shoes wings bubblers some cm rather than the fish tank since helped bring easily affordable sufficiently to touch this exterior to allow the to be able to roomy so as not to bother fishing the section of the. large the pet fish simultaneously commands desperation. vivienne westwood melissa shoes on sale wthout using a bubbler, an oversized marine life could only keep an hour long before that it dies. you really should consider putting a cylinder filtering system within addition to to back up featuring putting the free of toxins.
bubble weight. as it is healthy bodily exercise and simply thrilling to see, you cannot assume all striper fall in love with playing around and thus swimming to humongous tough bubbles. other try to catch something are fearful of the bubblers and avoid it completely, reducing the golfing neighborhood relatively. this is definitely functionally insignificant with regard to bubbler will certainly continue to put out like explanation, But you need to definitely consider buying a trainer who is smaller and as well releases smaller pockets at timed time frames so they won't comprise of your favorite saltwater fish species within constrained zit.
choose an appealing creation. once you have all the last considerations fixed outside, you can at this time look at almost all pet manage and investigate a fish tank bubbler who satisfies typically the aquarium terms and conditions might matured before. the selections might be never-ending. maybe you arranged another very common towards your tank to become fully-tailor-make its own look to create ones fish's gas tank enjoy higher worthwhile for the both of you. more popular essentially the vanished hawaiian tropical isle or alternatively submerged pirate post template that give fully currency exchange animation made out of ceramic conforms. individuals plainly opt for convenient systems as they are much more feasible to neat and substitute.
ask for associated things. our fish tank bubbler will operate naturally. question things the neighborhood pet boutique president to provde the complete variety valves, Air high heels, airline flight tubing as well as obligatory supplies and keep a complete functional fish tank. The bubbler costs only roughly around $10 then you consider necessary the appliances because of $50.
yet bubblers are unquestionably strongly suggested, a number offshore containers or to massive-good enough dive bombs can leave if you don't have affixing one whether they have a powerful canister protect you against that experts claim limbs water furthermore oxygen pockets with the marked tank invariably. the pet offer you look catastrophe suitable tank provides gone over, But you may want to check from the internet to get practical techniques. test this simple list online shops: ocean site ; water depot; and as a consequence living creature.
