Recently in Second Language Acquisition research much attention has been focused upon the cognitive mechanisms that underpin learner processing of input. In studies of how second language instruction has an effect on L2 learner’s subsequent processing of input, researchers have examined how external manipulation of input can affect intake and subsequent learning. In this literature review, input enhancement (an instantiation of manipulated input) will be examined in light of current cognitive psychological models of attention and memory. After reviewing current models of attention and memory as they pertain to SLA, previous input enhancement studies will be analyzed in order to see how input enhancement could affect L2 learner processing. Particular attention will be paid to the potential triggering effects of input enhancement as well as its impact upon second language learning.
