Concepts related to Second Language Acquisition

Hi everyone, surfing on the net I found this picture about the main concepts related to second language acquisition. I liked it  and I wanted to share with you. What do you think? Would you add some others concepts? Would you remove some others?

differences between FLA and SLA input and evidences

I would like to share a chart with differences between FLA and SLA input and evidences. It is a summary of one of the chapter of "General models of L2 learning" by cook. I really appreciate if you can tell me your opinion about that.

	FIRST LANGUAGE ACQUISITION	SECOND LANGUAGE ACQUISITION
INPUT	In the FLA, children apply the principles to the input that is encountered and adapt them to the right parameters according to the input.	In the SLA, the sentences the learners hear are the effective evidences.
POSITIVE EVIDENCE	The grammatical information in the sentences children hear allow them to construct grammatical rules of English.	It comes from linguistic input.
NEGATIVE EVIDENCE	Correction is sometimes considered ineffective (because it occurs rarely) if someone does it is usually focus on meaning rather than grammar.	Corrections of students’ grammatical errors occur much frequently.
