The English modal verbs are a subset of the English auxiliary verbs used mostly to express modality (properties such as possibility, obligation, etc.). They can be distinguished from other verbs by their defectiveness (they do not have participle or infinitive forms) and by their neutralization (that they do not take the ending -(e)s in the third-person singular).
The principal English modal verbs are can, could, may, might, shall, should, will, would, and must. Certain other verbs are sometimes, but not always, classed as modals; these include ought, had better, and (in certain uses) dare and need. Verbs which share only some of the characteristics of the principal modals are sometimes called "quasi-modals", "semi-modals", or "pseudo-modals".In decision theory and general systems theory, a mindset is a set of assumptions, methods, or notions held by one or more people or groups of people. A mindset can also be seen as arising out of a person's world view or philosophy of life.A mindset may be so firmly established that it creates a powerful incentive within these people or groups to continue to adopt or accept prior behaviors, choices, or tools. The latter phenomenon is also sometimes described as mental inertia, "groupthink", and it is often difficult to counteract its effects upon analysis and decision making processes.
In cognitive psychology, a mindset represents the cognitive processes activated in response to a given task (French, 2016).Permissions may refer to:
