Engelbart's law is the observation that the intrinsic rate of human performance is exponential. [further explanation needed] The law is named after Douglas Engelbart, whose work in augmenting human performance was explicitly based on the realization that although we use technology, the ability to improve on improvements (bootstrapping, "getting better at getting better") resides entirely ...
The Yerkes–Dodson law is an empirical relationship between arousal and performance, originally developed by psychologists Robert M. Yerkes and John Dillingham Dodson in 1908. [1] The law dictates that performance increases with physiological or mental arousal, but only up to a point. When levels of arousal become too high, performance decreases.
Human performance modeling (HPM) is a method of quantifying human behavior, cognition, and processes.It is a tool used by human factors researchers and practitioners for both the analysis of human function and for the development of systems designed for optimal user experience and interaction . [1]
In the field of human factors and ergonomics, human reliability (also known as human performance or HU) is the probability that a human performs a task to a sufficient standard. [1] Reliability of humans can be affected by many factors such as age , physical health , mental state , attitude , emotions , personal propensity for certain mistakes ...
Fitts's law is a principle of human movement published in 1954 by Paul Fitts which predicts the time required to move from a starting position to a final target area. Fitts's law is used to model the act of pointing, both in the real world, e.g. with a hand or finger, and on a computer, e.g. with a mouse.

Performance science is the multidisciplinary study of human performance. It draws together methodologies across numerous scientific disciplines, including those of biomechanics , economics , physiology , psychology , and sociology , to understand the fundamental skills, mechanisms, and outcomes of performance activities and experiences.

Hick's law, or the Hick–Hyman law, named after British and American psychologists William Edmund Hick and Ray Hyman, describes the time it takes for a person to make a decision as a result of the possible choices: increasing the number of choices will increase the decision time logarithmically. The Hick–Hyman law assesses cognitive ...
