# Hick's law

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 he or she has: increasing the number of choices will increase the decision time logarithmically.

## Binary search algorithm

In computer science, binary search, also known as half-interval search,logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array.

## Fitts's law

Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics.

## Franciscus Donders

Franciscus (Franz) Cornelius Donders FRS FRSE (27 May 1818 – 24 March 1889) was a Dutch ophthalmologist.

## Generalization

A generalization (or generalisation) is the formulation of general concepts from specific instances by abstracting common properties.

## Information theory

Information theory studies the quantification, storage, and communication of information.

## Linear function

In mathematics, the term linear function refers to two distinct but related notions.

## Linear map

In mathematics, a linear map (also called a linear mapping, linear transformation or, in some contexts, linear function) is a mapping between two modules (including vector spaces) that preserves (in the sense defined below) the operations of addition and scalar multiplication.

## Logarithm

In mathematics, the logarithm is the inverse function to exponentiation.

## Mental chronometry

Mental chronometry is the use of response time in perceptual-motor tasks to infer the content, duration, and temporal sequencing of cognitive operations.

In computing and telecommunications, a menu is a list of options or commands presented to the user of a computer or communications system.

## Morse code

Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment.

## Multiplicative inverse

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x&minus;1, is a number which when multiplied by x yields the multiplicative identity, 1.

## Power law of practice

The power law of practice states that the logarithm of the reaction time for a particular task decreases linearly with the logarithm of the number of practice trials taken.

## Ray Hyman

Ray Hyman (born June 23, 1928, Chelsea, Massachusetts) is a Professor Emeritus of Psychology at the University of Oregon in Eugene, Oregon, and a noted critic of parapsychology.

## Scientific law

A scientific law is a statement based on repeated experimental observations that describes some aspect of the universe.

## Sigmoid function

A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve.

## Stimulus (psychology)

In psychology, a stimulus is any object or event that elicits a sensory or behavioral response in an organism.

## Stimulus–response compatibility

Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action.
