The Model Human Processor, developed by Card, Moran and Newell, is a design tool that is used for creating an effective user interface. It draws an analogy between the processing and storage facilities in a computer system with the perceptual, cognitive, memory and motor activities of a computer user. The Model Human Processor describes how a user interacts with a computer system:

A visual or audible stimulus is captured.

 Once complete, the calculations can then be used to determine the probability of a user remembering an item that may have been encountered in the process. The following formula can be used to find the probability: P = e-K*t where K is the decay constant for the respective memory in question (working or long term) and t is the amount of time elapsed (with units corresponding to that of K). The probability could then be used to determine whether or not a user would be likely to recall an important piece of information they were presented with while doing an activity.
-It is important to deduce beforehand whether the user would be able to repeat the vital information throughout time t, as this has a negative impact on the working memory if they cannot. For example, if a user is reading lines of text and is presented with an important phone number in that text, they may not be able to repeat the number if they have to continue to read. This would cause the user’s working memory’s decay time to be smaller, thus reducing their probability of recall.

		+	The Model Human Processor is a model of a series of information flows in a human from the viewpoint of information processing (Fig. 1). In the model, sensory information is input to perceptual processor, and then processed in cognitive processor, and finally an action is output through the motor system by motor processor. The processing time in each processor and the storage capacity of each memory is indicated in the model. Each processing time of each processor is as follows. The perceptual processor is 100ms. The cognitive processor is 70ms. The motor processor is 70ms. Using every processing time, the model estimates reaction time from the input of the sensation information to the action output through the motor system (Fig. 2).In the Model Human Processor, human reactions are classified into four cases according to the number of times of processing by the cognitive processor. The four cases are Simple reaction, Physical collation reaction, Name collation reaction and Category collation reaction.Fig. 1. Model Human Processor
