Psychology. Mathematical psychology is an approach to psychological research that is based on mathematical modeling of perceptual, thought, cognitive and motor processes, and on the establishment of law-like rules that relate quantifiable stimulus characteristics with quantifiable behavior (in practice often constituted by task performance).
Deductive reasoning. Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the inference from the premises "all men are mortal" and " Socrates is a man" to ...
Karl Popper was born in Vienna (then in Austria-Hungary) in 1902 to upper-middle-class parents. All of Popper's grandparents were assimilated Jews; the Popper family converted to Lutheranism before he was born [ 13][ 14] and so he received a Lutheran baptism. [ 15][ 16] His father, Simon Siegmund Carl Popper (1856-1932), was a lawyer from ...
Forgetting curve. A representation of the forgetting curve showing retained information halving after each day. The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [ 1] A related concept is the strength of memory that refers to the ...
The word heuristic is taken directly from the Greek verb, heuriskein, 'to discover'. As a noun it is defined as 'a technique of discovery' and as an adjective, it means 'serving to guide, discover, or reveal'. The more common designation for all of this is 'the discovery method'.
Fourth power. In arithmetic and algebra, the fourth power of a number n is the result of multiplying four instances of n together. So: n4 = n × n × n × n. Fourth powers are also formed by multiplying a number by its cube. Furthermore, they are squares of squares. Some people refer to n4 as n “ tesseracted ”, “ hypercubed ...
A power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent . Powers of two with non-negative exponents are integers: 20 = 1, 21 = 2, and 2n is two multiplied by itself n times. [ 1][ 2] The first ten powers of 2 for non-negative values of n are:
In Experiment 2, participants completed either three or nine practice problems in one sitting. When participants were retested one or four weeks later, no differences were found between three-problem and nine-problem participants. Researchers found no effect of overlearning on mathematics retention. [4]
