A multiset may be formally defined as an ordered pair (A, m) where A is the underlying set of the multiset, formed from its distinct elements, and : + is a function from A to the set of positive integers, giving the multiplicity – that is, the number of occurrences – of the element a in the multiset as the number m(a).
In psychology, a set is a group of expectations that shape experience by making people especially sensitive to specific kinds of information. A perceptual set, also called perceptual expectancy, is a predisposition to perceive things in a certain way. [1]
Psychology is the scientific study of mind and behavior. [1] [2] Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of immense scope, crossing the boundaries between the natural and social ...
In set theory and related branches of mathematics, a family (or collection) can mean, depending upon the context, any of the following: set, indexed set, multiset, or class. A collection F {\displaystyle F} of subsets of a given set S {\displaystyle S} is called a family of subsets of S {\displaystyle S} , or a family of sets over S ...
This definition of disjoint sets can be extended to families of sets and to indexed families of sets. By definition, a collection of sets is called a family of sets (such as the power set, for example). In some sources this is a set of sets, while other sources allow it to be a multiset of sets, with some sets repeated.
A multiset is a special kind of set in which an element can appear multiple times in the set. Type theory. In type theory, sets are generally identified with ...
This task-switching model assumes the role of executive control. If the cue repeats, the executive does nothing, and the target is processed in accordance with the task set from the previous trial. If the cue alternates, the executive switches tasks before processing the target. Switching takes time and creates a switch cost.
Subpersonalities are functionally similar to possible selves, a concept used in cognitive psychology. [5] Possible selves are defined as psychological schema that represent multiple versions of the self. These include past and future selves, which together characterise thoughts and feelings, such as remorse, satisfaction, and doubt about the ...
