Picture arrangement test. Picture arrangement test is a test that consists of a series of comic-strip -like pictures that are presented in a random order. The subject is given the task to arrange the pictures as quickly as possible so that a reasonable and meaningful story is formed. This is an example of a common feature found in intelligence ...
First-order logic —also called predicate logic, predicate calculus, quantificational logic —is a collection of formal systems used in mathematics, philosophy, linguistics, and computer science. First-order logic uses quantified variables over non-logical objects, and allows the use of sentences that contain variables, so that rather than ...
A form of argument involving two conditional statements and their negated consequents, leading to the negation of at least one of the antecedents. determiner. A word, phrase, or affix that specifies the reference of a noun or noun phrase, such as "the", "some", "every". deterministic polynomial time.
Another form of logic puzzle, popular among puzzle enthusiasts and available in magazines dedicated to the subject, is a format in which the set-up to a scenario is given, as well as the object (for example, determine who brought what dog to a dog show, and what breed each dog was), certain clues are given ("neither Misty nor Rex is the German ...
For example, he believed that children experience the world through actions, representing things with words, thinking logically, and using reasoning. To Piaget, cognitive development was a progressive reorganisation of mental processes resulting from biological maturation and environmental experience.
Logic plays a fundamental role in computer science. Some of the key areas of logic that are particularly significant are computability theory (formerly called recursion theory), modal logic and category theory. The theory of computation is based on concepts defined by logicians and mathematicians such as Alonzo Church and Alan Turing.
List of paradoxes. Outline of public relations – Overview of and topical guide to public relations. Map–territory relation – Relationship between an object and a representation of that object (confusing map with territory, menu with meal) Mathematical fallacy – Certain type of mistaken proof.
Second-order logic is more expressive than first-order logic. For example, if the domain is the set of all real numbers, one can assert in first-order logic the existence of an additive inverse of each real number by writing ∀x ∃y (x + y = 0) but one needs second-order logic to assert the least-upper-bound property for sets of real numbers ...
