Introduction

Input is central to second language acquisition (SLA) theory and practice. Chapters 3–5 of W synthesize theoretical models and classroom techniques that explain how learners receive, notice, and process linguistic data. This paper summarizes interactional versus non-interactional input, explicates comprehensible input, reviews VanPatten's (1996) and Gass's (1997) models of processing, and evaluates pedagogical techniques—input enhancement, input flood, and textual enhancement—together with practical classroom implications and sample activities (VanPatten, 1996; Gass, 1997).

Interactional vs. Non-Interactional Input

Interactional input arises in communicative exchanges where negotiation of meaning, feedback, and listener adjustments occur (e.g., conversations, teacher-student talk). Non-interactional input includes monologic or pre-prepared input such as stories, lectures, or readings. Interactional input often provides opportunities for uptake and clarification, increasing the chances that learners will notice and process particular forms (Gass, 1997). Non-interactional input can be controlled and manipulated easily (e.g., by flooding a target structure), but lacks immediate negotiation and feedback.

Comprehensible Input

Comprehensible input refers to language that learners can understand despite incomplete knowledge of all forms (Krashen, 1985). Comprehensibility is enhanced by context, gestures, visual aids, and simplification. In classrooms, teachers can increase comprehensibility by following grammatical clarity, providing contextual information, and monitoring learners’ responses to scaffold further clarification (Lightbown & Spada, 2013).

VanPatten’s Input-Processing Model

VanPatten (1996) conceptualizes SLA processing as a flow from input to intake to a developing system to output, with working memory central to initial input processing. Learners prioritize meaning over form; thus, form-meaning mapping can be disrupted if processing resources are taxed. System change occurs via accommodation and restructuring, and output reflects processing and system state (VanPatten, 1996). Pedagogical implication: tasks should manage processing load to allow form detection without sacrificing meaning.

Gass’s Stages: Apperception to Output

Gass (1997) proposes sequential stages: apperceived input (noticing that something is learnable), comprehended input (analyzing input for meaning), intake (what is stored), integration (incorporation into developing system), and output. Gass emphasizes learner activity in apperception and integration; learners are not passive recipients but must attend and reorganize knowledge (Gass, 1997). The two models share the centrality of comprehending and noticing input but differ in emphasis: working memory and processing constraints (VanPatten) versus the learner’s active apperception and integration (Gass).

Input Enhancement: Positive and Negative

Input enhancement (I-E) aims to make target features more salient in input, drawing attention without explicit instruction. Positive I-E highlights correct target forms (e.g., bolding -s on third-person verbs); negative I-E flags errors to draw attention to deviations. Both rely on the premise that increased salience raises the probability of noticing and intake (Doughty & Williams, 1998). However, enhancement alone cannot guarantee form-meaning mapping; it must preserve meaning to be effective.

Input Flood

Input flood saturates materials with multiple exemplars of a target feature embedded in meaning-bearing texts or speech (Trahey & White, 1993). Flooding increases frequency and opportunity for noticing without explicit highlighting. Studies show mixed results: input flood can improve accuracy for some structures (Trahey & White, 1993; Williams & Evans, 1998), but effectiveness varies by target form and learner level. Classroom use: create reading passages, listening scripts, or task sequences where a target form appears repeatedly in natural contexts (example: multiple texts with frequent passive constructions or second-person subjunctive forms).

Textual Enhancement

Textual enhancement uses typographical cues—bold, underline, color—to draw attention to forms in written input. It is easy to implement and compatible with meaning-focused lessons (Bardovi-Harlig & Reynolds, 1995). Empirical results show partial effectiveness: enhanced forms attract attention but do not always produce intake or integration unless learners process form-meaning relationships (Doughty & Williams, 1998). Best practice: align enhancement with comprehension tasks so noticing leads to meaningful processing.

Pedagogical Implications and Classroom Activities

1. Maintain meaning focus: All input-based techniques work best when embedded in meaningful tasks. Input flood and textual enhancement should not disrupt comprehension; instead they should be integrated into content-rich lessons (Doughty & Williams, 1998). Example activity: a history reading where the teacher floods past-tense irregulars, followed by comprehension questions that require using those forms.

2. Support noticing and processing: Pair enhancement with activities that force form-focused processing—recasting, reconstructing stories, error-detection tasks, or grammar consciousness-raising tasks (VanPatten, 1996). Example: after reading a flooded text, students complete reconstruction or transformation tasks that require attending to the target structure.

3. Use interactional opportunities: Combine non-interactional materials (flooded texts) with interactional follow-ups—peer discussion, role-plays, or information gaps—where feedback and negotiation can trigger uptake (Gass, 1997).

4. Differentiate by target form and proficiency: Some structures benefit from explicit instruction plus input flood (Williams & Evans, 1998). Assess whether a form is learnable through distributional exposure alone or requires metalinguistic explanation.

Conclusion

Chapters 3–5 of W tie SLA theory to practical classroom methods. Interactional and non-interactional input each have advantages: interactional input affords negotiation and feedback, while non-interactional input is easy to manipulate for floods and enhancements. VanPatten and Gass provide complementary process models emphasizing working memory and learner agency, respectively. Input enhancement, input flood, and textual enhancement are valuable tools when they preserve meaning and are paired with tasks that encourage noticing, processing, and integration (VanPatten, 1996; Gass, 1997; Doughty & Williams, 1998).
