Definition:
Implicit corrective feedback is a type of corrective feedback in which an interlocutor or teacher responds to a learner’s erroneous form in a way that targets the error without explicitly drawing attention to it as an error. The learner receives the correct form embedded in a natural conversational move, without being told “that was wrong” or being given a grammar rule. The most researched type of implicit feedback is the recast — in which the interlocutor reformulates the learner’s erroneous utterance in the target form while maintaining the same meaning and continuing the communicative exchange: Learner: “Yesterday I goed to school.” Teacher: “Oh, you went to school yesterday. What did you do there?” The Noticing Hypothesis predicts that learners must notice the gap between their production and the recast to benefit; research investigates when and for whom this noticing happens.
Types of Corrective Feedback
| Type | Explicitness | Definition | Example |
|---|---|---|---|
| Recast (implicit) | Implicit | Reformulation of error maintaining meaning | L: “I eated cake.” T: “You ate cake! Was it good?” |
| Clarification request (implicit) | Implicit | Expression of non-understanding, invites reformulation | “Sorry, I didn’t quite understand—could you say that again?” |
| Metalinguistic feedback (explicit) | Explicit | Comment on the form of the error | “That’s not quite right — remember the past tense of eat is ate“ |
| Explicit correction (explicit) | Explicit | Direct identification and correction of error | “No, the correct form is I ate, not I eated“ |
| Elicitation (semi-implicit) | Semi-implicit | Prompt for learner self-correction | “I ate… I…” (pause + rising intonation) |
How Implicit Feedback Works
For implicit feedback to facilitate acquisition:
- Noticing: Learner must notice that a reformulation or response signals their error was wrong (this requires uptake)
- Comparison: Learner compares their erroneous form and the correct form
- Hypothesis revision: Learner updates their interlanguage representation
Recasts in Research
Recasts are the most frequent type of teacher feedback in L2 classrooms (Lyster & Ranta, 1997). However:
- In communicative classrooms, recasts often pass unnoticed because they flow naturally in conversation
- Learners with higher proficiency and metalinguistic awareness benefit more from recasts
- Certain error types (more salient, more discrete form–meaning mappings) respond better to recasts
Implicit vs. Explicit Feedback: Which is Better?
Meta-analyses (Mackey & Goo, 2007; Russell & Spada, 2006) suggest:
- Both implicit and explicit feedback are effective
- Explicit feedback may produce faster short-term gains on targeted forms
- Implicit feedback may be more naturalistic and less disruptive to communication
- The optimal choice depends on error type, learner proficiency, and instructional context
History
The study of corrective feedback types was systematized by Lyster & Ranta (1997)’s foundational classroom observational study, which identified six feedback types and introduced the Lyster–Ranta taxonomy. This research triggered a wave of experimental studies comparing implicit and explicit feedback effects.
Common Misconceptions
- “Recasts are always understood as corrections” — in communicative classrooms, learners often interpret recasts as confirmations of meaning rather than corrections; the corrective intent is frequently missed
- “Implicit feedback never works” — recasts do facilitate acquisition, particularly for more salient forms and with more advanced learners
Criticisms
- Purely implicit feedback (especially recasts in communicative interaction) may be insufficient for some grammar features — particularly complex or low-salience rules — suggesting a role for explicit feedback on difficult features
Social Media Sentiment
L2 teachers debate whether to correct errors or let communication flow; the recast vs. explicit correction debate maps onto broader anxiety about disrupting communicative fluency. Last updated: 2026-04
Practical Application
- Use recasts freely in communicative tasks; monitor learner uptake to assess effectiveness
- For persistent errors on learnable forms, shift toward more explicit feedback or metalinguistic comment
