Human processor model

Human information processor model is a cognitive modeling method used to calculate how long it takes to perform a certain task. Other cognitive modeling methods include parallel design, GOMS, and KLM (human-computer interaction). Cognitive modeling methods are one way to evaluate the usability of a product. This method uses experimental times to calculate cognitive and motor processing time. Other modeling methods include inspection methods, inquiry methods, prototyping methods, and testing methods.

is a method of modeling human abilities and cognitive processes in human-computer interaction. A deliberately simplified view of human cognition, called the model human processor (MHP), is used to explain and predict how a human responds to stimulus. The model human processor is composed of memories and processors. The memories are characterized by storage capacity, decay time and type of coding, and the processors by cycle time. The values of these attributes were determined by empirical studies.
