“…Th e impaired comprehension of sentences with dative object Experiencers in our AD patients is surprising, considering the multiple cues to meaning, in particular in the OVS order where the preposition a, indicating an animate object, appears in the sentence initial position. Evidence involving neurologically intact population, including child language, as well as post-stroke aphasic patients (Kail & Charvillat 1988;Ostrosky-Solis et al 1999;Kljajevic et al 2019) converges in suggesting that this specifi c cue to animate objects in Spanish typically facilitates comprehension of the Patient role in agentive context. In the present study, AD patients comprehended above chance sentences with action verbs involving dative objects in both word orders, but they failed to comprehend sentences with psych verbs taking dative Experiencers.…”

Patients with Alzheimer's disease (AD) show a defi cit in processing sentences with psychological verbs. Evidence from English suggests that their comprehension of object Experiencers is more impaired relative to subject Experiencers. Since Spanish is structurally diff erent from English, in the present study we wanted to determine whether Spanish-speaking AD patients would show a diff erent comprehension pattern. We tested comprehension of semantically irreversible sentences involving psych verbs with subject Experiencers, and accusative-and dative-marked object Experiencers in 10 native speakers of Spanish diagnosed with mild to moderate AD. We also tested their comprehension of semantically reversible sentences involving dative object Experiencers in two word orders (SVO, OVS). A paired-samples t-test revealed no statistically signifi cant diff erences in their comprehension of subject vs. object Experiencers, or accusative vs. dative object Experiencers in semantically irreversible sentences, with one-sample t-test indicating comprehension above chance. However, their overall comprehension of psych verbs in semantically reversible sentences was poor, regardless of word order, and it was signifi cantly worse than their comprehension of sentences with action verbs in the same word orders. Th us, our data indicate that the defi cit in comprehension of psych verbs found in Spanish speakers with mild to moderate AD dementia diff ers from the pattern found in English, and that the defi cit in AD patients' comprehension of psych verbs is more heterogeneous than previously thought.
