Decay theory refers to a theory that asserts that information is forgotten because of the gradual disappearance, rather than displacement, of the memory trace. Decay theory is an explanation for loss of information in short-term memory based on the notion that the physiological effects of stimulation fade. Decay theory is similar to Fading in connection with forgetting in long-term memory . (see Fading.)
conformity to recognized standards of propriety, good taste, and modesty as defined by a particular group. Standards of decency differ among groups or cultures. What might be decent to one group or culture might not be decent to other groups or cultures. Example: in some countries in Africa it is decent to be bare breasted even in oublic, but in other countries it is indecent to be bare breasted when in public.
