Introduction Knowledge acquired by researchers through developmental psychology research is that individual development gradually occurs from birth to various living processes in the surrounding environment and people around them (especially mothers). They tend to acquire communication skills closely related to the emotions experienced at a particular time, and thus they already know what emotions or actions correspond to the words they speak.
Intellect is one aspect of language development. If society is multilingual, after Ferguson (1968) and Hogan (1968), language development usually selects living languages as the basis of national languages; once selected, the language leads to languages I will. Spread within the geographical area. As it spreads and as it grows increasingly it goes through a standardized process whose format and structure more or less matches the social consensus between the speakers or the statements of the National Planning Agency. This standardization is usually organized by grammar (for various purposes, especially for education) and dictionaries. Where a language is planned, it is considered by the person responsible for such work in society (usually a member of a language school) and is normally given the status by the legislature or administrative agencies (officers, countries, etc.) I will.
The final stage of language development is the cultivation stage, which has many aspects. In many cases, national languages are cultivated in imaginative literature, mass media, guidance medium in basic education system, governance language, and scholarly discourse. The intellectual stage includes not only vocabulary expansion (by modern term) but also styling differences (syntactic devices using different types of prose text). Intelligence is regarded as a process and a product and is based on its essential (psychological) dimension and external (sociological) dimension.
