• the cognitive process which occurs when input is understood and integrated into interlanguages (VanPatten, 2002) • the conditions under which learners may attempt to make connections between form in the input and meaning (VanPatten, 2004) • Most studies on input treat issues such as linguistic properties of input and modification of input. Input processing is rather a new focus of research in second language acquisition. Therefore, a model of input processing needs to be developed (VanPatten, 1996). • Traditional approach to grammar instruction consists of drills in which learner output is manipulated and the instruction is divorced from meaning or communication. As a result, an input-based approach to grammar instruction is required (Lee & Benati, 2009). • It is important to differentiate the terms “Input Processing” and “Processing Instruction”. • IP refers to what is assumed to occur in the brain on perceiving input. • PI refers to what the teacher has the learners do in order to notice the grammar of the input.
