The academic discipline of second-language acquisition is a sub-discipline of applied linguistics.It is broad-based and relatively new. As well as the various branches of linguistics, second-language acquisition is also closely related to psychology and education.
The second part of a-fronting, called Anglo-Frisian brightening or First Fronting, is very similar to the first part except that it affects short a instead of long ā. Here a [ɑ] is fronted to æ [æ] unless followed by /n, m/ or nasalized, the same conditions as applied in the first part. [4]
In mammals, the term refers chiefly to the early stages of prenatal development, whereas the terms fetus and fetal development describe later stages. [2] [4] The main stages of animal embryonic development are as follows: The zygote undergoes a series of cell divisions (called cleavage) to form a structure called a morula.
The models of the process-oriented period explore the short-term and long-term changes in the individuals’ motivation as they learn L2. This approach views motivation as a dynamic factor which fluctuates within a class period, a year, and a lifetime. [3] Models from this period include the process model and the motivational self-system.
In addition, Krashen (1982)’s Affective Filter Hypothesis holds that the acquisition of a second language is halted if the learner has a high degree of anxiety when receiving input. According to this concept, a part of the mind filters out L2 input and prevents intake by the learner, if the learner feels that the process of SLA is threatening.
In the second stage of group development members disagree among themselves about group goals and procedures. Conflict is an inevitable part of this process. The group's task at Stage 2 is to develop a unified set of goals, values, and operational procedures, and this task inevitably generates some conflict.
This process is called zona hatching and it takes place on the sixth day of embryo development, immediately before the implantation process. The hatching of the human embryo is supported by proteases secreted by the cells of the blastocyst, which digest proteins of the zona pellucida, giving rise to a hole.
