“…In particular, patients' bias towards concreteness patterned with lower neurocognitive skills, especially executive functioning, and lower mentalizing ability. This mirrors the link between pragmatic impairment and cognitive and sociocognitive deficits extensively documented in schizophrenia (Bambini et al, 2016;Binz & Brüne, 2010;Parola et al, 2018; for a comprehensive view, see Frau et al, 2024), and observed here as well (see Supplementary Figure S2). However, we did not find a direct correlation between the bias toward concreteness and symptomatology, in particular lack of abstract thinking as measured in item N5 of the PANSS.…”

“…From Bleuler's initial idea of "disordered conceptual associations", concretism in schizophrenia has received several explanations, related to more general difficulties in abstract conceptualization (Wright, 1975), altered organization of semantic networks in associative memory (Spitzer, 1993) or, more recently, impaired cognitive and sociocognitive mechanisms (see Frau et al, 2024). Little consideration has been paid to the idea that concretism -at least for what concerns its pragmatic manifestation -could be linked to difficulties in core aspects of language processing.…”

Lack of abstract thinking, known as concretism, is a well-known psychopathological feature of schizophrenia, reflecting the tendency to adhere to concrete aspects of stimuli and difficulties in understanding figurative language. Inspired by the similarity between “concretism” as defined in psychopathology and “concreteness” as defined in linguistics, namely a semantic dimension linked to perceptual experience, we tested the novel hypothesis that impairment in deriving figurative meanings is related to impairment at the semantic level, involving concreteness. We analyzed speech samples from 63 patients with schizophrenia and 47 controls, who were asked to verbalize the meaning of idioms, metaphors, and proverbs. By automatically extracting linguistic features from speech, we observed that patients’ answers exhibited higher word concreteness values and the related measure of word imageability, especially in proverbs, while not differing from controls’ ones in lexical richness and speech time composition. Concreteness in patients’ verbalizations negatively predicted their ability to understand proverbs and their global pragmatic and cognitive profile. This study supports the idea that concretism is rooted in semantics, linking the tendency to concrete figurative interpretations and a bias towards concrete words. In this view, impairment in figurative language understanding can be seen as a difficulty in abstracting away from perceptual-related properties associated with linguistic inputs, in the broader context of multisensory integration disruption. Furthermore, the study discloses new areas of interest for the automated analysis of speech in psychosis, pointing to the importance of considering concreteness for a better characterization of linguistic profiles and for identifying clinically relevant linguistic dimensions.
