Perhaps Barsalou’s most notable contribution to the field of cognitive psychology is his research on ad hoc, or goal-derived, categories. Prior to this work, the vast majority of research on the cognitive representation of categories dealt solely with taxonomic categories, in which category membership is established due to overlap in both conceptual and physical features.
In economics, rationalization is an attempt to change a pre-existing ad hoc workflow into one that is based on a set of published rules. There is a tendency, in modern times, to quantify experience, knowledge, and work.
Ad hoc is a Latin phrase meaning literally ' for this '. In English , it typically signifies a solution designed for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances (compare with a priori ).
Rationalization encourages irrational or unacceptable behavior, motives, or feelings and often involves ad hoc hypothesizing. This process ranges from fully conscious (e.g. to present an external defense against ridicule from others) to mostly unconscious (e.g. to create a block against internal feelings of guilt or shame).
In science and philosophy, an ad hoc hypothesis is a hypothesis added to a theory in order to save it from being falsified.. For example, a person that wants to believe in leprechauns can avoid ever being proven wrong by using ad hoc hypotheses (e.g., by adding "they are invisible", then "their motives are complex", and so on).
The Ad Hoc Configuration Protocol (AHCP) is an autoconfiguration protocol for IPv6 and dual-stack IPv6/IPv4 networks designed to be used in place of router discovery and DHCP on networks where it is difficult or impossible to configure a server within every link-layer broadcast domain, for example mobile ad hoc networks.
The ad-hocs are administered by an artificial intelligence and polled from suitably qualified individuals who are judged by the AI to have sufficient experience. Failure to arrive at a decision results in the polling of a new ad-hoc, whose members are not told of previous ad-hocs before hearing the decision which must be made.
In economics, psychology, and other social sciences, regression analysis is typically used deductively to test hypotheses, but a kitchen sink regression does not follow this norm. Instead, the analyst throws " everything but the kitchen sink " into the regression in hopes of finding some statistical pattern.
