Is anaphoric reference cooperative?

Two experiments investigated whether the choice of anaphoric expression is affected by the presence of an addressee. Following a context sentence and visual scene, participants described a target scene that required anaphoric reference. They described the scene either to an addressee (Experiment 1) or without an addressee (Experiment 2). When an addressee was present in the task, participants used more pronouns and fewer repeated noun phrases when the referent was the grammatical subject in the context sentence than when it was the grammatical object and they used more pronouns when there was no competitor than when there was. They used fewer pronouns and more repeated noun phrases when a visual competitor was present in the scene than when there was no visual competitor. In the absence of an addressee, linguistic context effects were the same as those when an addressee was present, but the visual effect of the competitor disappeared. We conclude that visual salience effects are due to adjustments that speakers make when they produce reference for an addressee, whereas linguistic salience effects appear whether or not speakers have addressees. </jats:p

No looking back:The effects of visual cues on the lexical boost in structural priming

Four structural priming experiments investigated the lexical boost effect in structural priming. In two experiments, we tested whether repeating the subject in prepositional object or double object ditransitive structures boosted structural priming. In two other experiments, we manipulated the repetition of the verb. Repetition of the subject noun affected structural priming, but only when the prime remained visible while participants produced the target sentence. In contrast, repetition of the verb boosted priming regardless of whether participants could see the prime and target simultaneously. We conclude that the subject noun repetition effect is more strategic in nature than the verb boost effect. Structures are automatically associated with the verb, their syntactic head, whereas repetition of the subject noun only affects priming if the presentation method makes the repetition highly explicit.</p

The head or the verb:Is the lexical boost restricted to the head verb?

Four structural priming experiments investigated whether the lexical boost is due to the repeated head verb of the primed structure or due to the repetition of any verb, testing structural priming of ditransitive structures (The hotel owner decided to loan the tourist a tent/a tent to the tourist). In Experiments 1–3, we manipulated the repetition of the matrix verb (decided) that is not the syntactic head in the primed structure. The results showed abstract structural priming of the embedded ditransitive structure but the repetition of the matrix verb did not boost the priming. In addition to manipulating the repetition of the matrix verb, we also manipulated the head verb of the primed structure (loan) in Experiment 4. It showed a lexical boost with the repetition of the head verb but no boost with the repetition of the matrix verb. These results are consistent with the residual activation model, which only predicts a boost from the verb that is the head of the primed structure. They do not support models which predict that the repetition of any lexical material in a sentence boosts priming
