Individual Differences In Second Language Acquisition

 One of the most confusing and debatable issues in second language acquisition is the issue of individual differences that affect the success of mastering a L2. There is much evidence that all individuals without any mental disabilities can acquire their first language L1 successfully. Some of the  widely recognized differences which play an important role in the SLA are age, motivation, aptitude, personality traits, individual preferences in learning process, and others.
For example, research study on the effect of age on SLA shows that young students are more successful in SLA than older students. Students who are most successful in learning a foreign language due to the flexibility of the brain until the age of 10 make the natural learning process possible. Researchers note that young students can get good, native-like pronunciation. The second important individual difference affecting SLA is motivation. Motivation can be defined as a reason or incentive to perform certain tasks. Both teachers and students are aware of the importance of motivation in SLA. To sum up, there are several differences in this option, including the age, motivation and ability you have chosen for the success of SLA.
