Noticing

Noticing refers to the conscious, focused attention a learner pays to a specific feature in the language input. Richard Schmidt (1990) proposed the Noticing Hypothesis, which states that nothing is acquired from input unless the learner first consciously notices it. This claim has been influential and contested in equal measure — but it has shaped decades of research into attention, awareness, and input enhancement in SLA.

In-Depth Explanation

The Noticing Hypothesis

Schmidt argued that there are three levels of awareness relevant to SLA:

  1. Noticing: detecting that something exists in the input
  2. Understanding: grasping the rule or pattern behind what was noticed
  3. Noticing the gap: seeing a mismatch between your current output and the target form

Only noticing was claimed to be necessary for acquisition; understanding a rule was helpful but not required. See Noticing Hypothesis for the full theoretical treatment.

Noticing vs Implicit Learning

The claim that noticing is necessary for acquisition puts Schmidt in tension with research on implicit learning, which shows that language patterns can be acquired through exposure without awareness. The current consensus is more nuanced: some features (especially phonological patterns and high-frequency collocations) can be acquired implicitly, while morphosyntactic rules may require at least some degree of noticing.

Noticing the gap

A specific form of noticing with strong implications for output practice. When learners try to produce language and realize they cannot, or produce something and compare it to native speaker output, they notice the gap — the space between their current ability and the target. This is thought to be a particularly powerful driver of acquisition. See Pushed Output and Output Hypothesis.

History

The concept of noticing in SLA originates in Schmidt’s and Frota’s 1986 case study diary — a detailed record of Schmidt learning Portuguese in Brazil, in which he documented which features he “noticed” in input and which appeared in his subsequent output. The study suggested a strong correlation between noticed features and acquired features. Schmidt formalized the Noticing Hypothesis in his 1990 paper “The Role of Consciousness in Second Language Learning” (Applied Linguistics, 11/2), arguing that consciousness is always necessary for acquisition and that purely subliminal acquisition of grammar is impossible or at least insufficient. The paper became one of the most cited in SLA. Schmidt revised and qualified the hypothesis in subsequent papers (1993, 1994, 2001), distinguishing between noticing (registration) and noticing-the-gap (comparison), and acknowledging that not all noticing leads to acquisition. The concept energized a generation of research into input enhancement, focus-on-form instruction, and attention models in SLA.

Common Misconceptions

  • “Noticing is the same as understanding a rule.” Schmidt was explicit: noticing is detection, not comprehension. You can notice that a form exists without understanding its grammatical function — and noticing alone may be sufficient for eventual acquisition.
  • “Implicit learning is impossible.” Schmidt did not deny implicit learning of all linguistic features; subsequent research has shown phonological pattern learning can occur without awareness. The hypothesis is strongest for morphosyntax, not phonology or collocation.
  • “Noticing always leads to acquisition.” Noticing is proposed as necessary but not sufficient. Forms can be noticed repeatedly without shifting into production if they don’t become fully integrated into intake and processing.
  • “You can’t acquire Japanese grammar without studying it explicitly.” The noticing-focused view doesn’t require explicit rule study — it requires awareness of the form. Input enhancement (seeing forms in bold or marked text, or hearing recasts) can promote noticing without a grammar lesson.

Social Media Sentiment

Noticing as a concept appears frequently in immersion-heavy communities (r/LearnJapanese, AJATT, MattVsJapan) disguised under the idea of “picking things up” vs. “studying.” Many immersionist arguments implicitly rely on the tension between Schmidt’s noticing requirement and implicit learning — with immersionists arguing that massive exposure allows sufficient noticing via volume, while study-first advocates argue that explicit attention speeds the process. The academic term “noticing” is rarely used in these communities, but the underlying debate is constant. Professional educators and teachers are more likely to use the term directly.

Practical Application

  • Input enhancement: Bolding, underlining, or using color to highlight target forms in reading material increases the likelihood learners notice them without stopping the flow of reading.
  • Consciousness-raising tasks: Drawing explicit attention to grammatical patterns before or after exposure.
  • Corrective feedback and recasts: When a teacher repeats a learner’s error in corrected form, it creates the opportunity to notice the gap.
  • Dictogloss and form-focused tasks: Force attention to specific features during listening and reconstruction activities.
  • For Japanese learners: Sentence mining (as in Anki) is partly a noticing-facilitation tool — selecting sentences where a target grammar point is visible and creating a context that forces attention to it.
