Cross-linguistic influence, what teachers used to call transfer, and what we know now.

Scott Jarvis and Aneta Pavlenko cleaned up forty years of confused thinking about how a learner's first language affects their second. The category we used to call interference turns out to be a much more interesting set of effects than the negative framing suggested.

From transfer to influence

The term transfer comes from the contrastive analysis tradition of the nineteen fifties (Lado, Linguistics Across Cultures, 1957). The early framework predicted that L2 errors would correlate with differences between the L1 and the L2. Difficulty maps onto difference. The prediction turned out to be only partly right. Many errors were L1-based. Many were not. The framework was not wrong but it was incomplete.

Scott Jarvis and Aneta Pavlenko's 2008 book (Crosslinguistic Influence in Language and Cognition, Routledge) re-cataloged the field. They proposed replacing the loaded term transfer (which sounds like the L1 is contaminating the L2) with the neutral term crosslinguistic influence (CLI). The L1 affects the L2 in many ways, some helpful, some unhelpful, some neither. The framing matters.

The taxonomy that helps

Jarvis and Pavlenko identify multiple dimensions along which the L1 can influence the L2. The most useful for teachers are these four.

Positive transfer

L1 features that match L2 features make acquisition faster. English speakers learning Spanish have an advantage with cognate vocabulary (millions of words roughly shared), Latin alphabet, basic SVO word order, articles, plurals, prepositions, copula constructions. These do not need to be acquired from scratch. They are recognized.

Negative transfer

L1 features applied to L2 contexts where they do not work. The English speaker who says yo soy quince años is transferring the be-construction from English. The result is wrong Spanish. The traditional label was interference. The mechanism is L1 procedural knowledge misfiring in L2 production.

Avoidance

Forms that exist in the L2 but not in the L1 (or are very different) tend to be avoided. English speakers avoid the Spanish subjunctive. Japanese speakers learning English avoid articles. The form is not used wrong. It is not used at all. Schachter (1974, An Error in Error Analysis, Language Learning) showed that pure error counts miss this whole category.

Conceptual transfer

The most interesting category in the Jarvis and Pavlenko framework. The L1 organizes concepts in ways the L2 does differently. English speakers carve up the color spectrum differently from Russian or Vietnamese speakers. English speakers carve up motion verbs differently from Spanish speakers (English has many verbs of manner of motion, Spanish has fewer). Spanish speakers carve up emotion states differently from English speakers.

The L2 learner is learning more than new words. Sometimes they are learning to carve concepts in new ways. Heritage learners often have this part already done. L2 learners often resist it because their conceptual organization is already in place.

Crosslinguistic influence is not a single phenomenon but a family of effects, some positive, some negative, some too subtle to map onto traditional error categories.

Specific Spanish-from-English transfer effects

The literature has documented many specific patterns worth knowing. Salaberry and Lafford's 2006 edited volume (The Art of Teaching Spanish) is the standard Spanish-applied reference.

Helpful transfers

Cognate vocabulary (educación, importante, situación, historia). Basic word order. Subject pronouns (though they get dropped in Spanish more than students expect). Object pronouns (though they precede the verb, unlike English). Adjectives (though they follow the noun and agree).

Unhelpful transfers

The be construction (transferred onto age, hunger, thirst, expressions like tener miedo). The present continuous (overextended to translate English present continuous in contexts where Spanish uses the simple present). Word-for-word translations of English idioms. The personal a (omitted, because English does not mark direct objects with a preposition).

Avoidance patterns

The subjunctive in all its uses. Reflexive verbs (which get avoided in favor of active constructions). The passive se. Subject-pronoun omission. The future tense (in favor of the periphrastic ir a + infinitive).

The Spanish-from-Spanish question for heritage learners

Heritage learners face a different CLI situation. Their L1 is not English; it is a variety of Spanish, often with some English mixed in. The standard variety of Spanish taught in school is not the same as the family Spanish at home. The result is bidirectional influence within the same language.

Heritage learners may transfer features from their family dialect into the formal register the school expects. This is not error in the same sense as L2 transfer error. It is dialectal variation being treated as error by an instruction that has chosen a particular prestige variety as the target. The CLI framework, used carefully, gives teachers a vocabulary for talking about this without treating heritage Spanish as deficient.

Why this matters for instruction

Three implications.

Plan for predictable transfer errors, do not punish them

The English-to-Spanish transfers are well documented. Plan for them. Teach them as the predictable cognitive consequence of having an L1 mind, not as careless mistakes. The student who says yo soy quince años is doing exactly what every English speaker initially does when learning Spanish. The correction is part of the path, not evidence of a problem.

Use positive transfer aggressively

Cognate vocabulary, shared structures, and parallel constructions are free acquisition. Maximize them in early instruction. The first-year student who learns to read cognate-rich Spanish text is exploiting positive transfer to read above their level.

Address conceptual transfer explicitly

The hardest CLI category to address. The English speaker's ser-versus-estar problem is conceptual, not just grammatical. They are mapping a one-copula system onto a two-copula system. Explicit attention to the conceptual difference matters. The student who has a procedural rule for ser-vs-estar but not the underlying concept will fossilize on the procedural rule and never use the contrast productively.

What this means for your Monday

Pull a writing sample from your Spanish 2 class. Mark each error. Categorize each one against the four CLI types. Positive transfer (got it right because of English match). Negative transfer (got it wrong because of English mismatch). Avoidance (did not use a form they should have used). Conceptual transfer (got a structural feature procedurally right but used it in a conceptually wrong way).

The distribution tells you what your unit needs. Heavy negative transfer on a specific feature means explicit contrastive teaching is overdue. Heavy avoidance means the form needs to be made required. Heavy conceptual transfer means the form has been drilled procedurally but the underlying meaning has not been built. Each category points to a different instructional fix.
