“…All participants were native speakers of Polish, Caucasian, and of Polish ethnicity. Demographic information for all participants and clinical information for patients can be found in Table 1 and more detailed data can be found elsewhere (Pawełczyk, Kotlicka-Antczak, Łojek, Ruszpel, et al, 2017).…”

“…Impaired cognition (Kurtz & Marcopulos, 2012) as well as language deficits are also the main features of this disease (Andreasen, 1979c;Andreasen, Arndt, Alliger, Miller, & Flaum, 1995;Kuperberg, 2010aKuperberg, , 2010bPawełczyk, Kotlicka-Antczak, Łojek, Ruszpel, & Pawełczyk, 2017). The most obvious clinical manifestation of language impairments are: disorganized and unintelligible speech, with tangentiality, derailment, incoherent speech, perseveration, and echolalia or "poverty of speech" being frequently observed (Andreasen, 1979).…”

“…They also exhibit deficits in verbal fluency, especially in category fluency (Bokat & Goldberg, 2003;Kremen, Seidman, Faraone, & Tsuang, 2003). Higher order language functions, such as humor and irony, understanding discourse and metaphor processing, and prosody are believed to be disturbed in SZ patients as well (Kuperberg, 2010a(Kuperberg, , 2010bPawełczyk, Kotlicka-Antczak, Łojek, Ruszpel & Pawełczyk, 2017). Also, impairments of pragmatic language are observed in very early stages of the disease: in people in an at-risk mental state and in first episode of the illness .…”

“…Many studies have shown that metaphor comprehension is disturbed in SZ patients in various stages of the illness (Bryan, 2014;Mashal et al, 2013;Mossaheb et al, 2014;Pawełczyk, Kotlicka-Antczak, Łojek, Ruszpel, et al, 2017;. It was also suggested that comprehension of metaphors may not differentiate patients from controls, however, the ability to explain these metaphors may (Pawełczyk, Kotlicka-Antczak, Łojek, Ruszpel, et al, 2017).…”

There are few studies which also indicated an influence of negative symptoms on metaphor comprehension (Mossaheb et al, 2014) and an influence of thought disorder on metaphor understanding (Iakimova, Passerieux, & Hardy-Bayle, 2006).…”

The study assessed the quantity and quality of errors made by schizophrenia patients in understanding and interpretation of the same metaphors, to evaluate metaphor understanding and explanation depending on the type of presentation material, and to analyze the correlation of illness symptoms with metaphor comprehension and explanation. Two groups of participants were examined: a schizophrenia sample (40 participants) and a control group (39 participants). Metaphor processing was assessed by the subtests of the Polish version of the Right Hemisphere Language Battery (RHLB-PL). The patients were also evaluated with the Positive and Negative Syndrome Scale (PANSS). Schizophrenia patients scored significantly lower in explanation of metaphors, making more incorrect literal and abstract mistakes or providing no answer more frequently. No differences were observed in understanding metaphors; no correlation between symptoms and metaphor processing was obtained. In both groups, picture metaphors were easier to comprehend and written metaphors were easier to comprehend than to explain.

An evolutionary account of impairment of self in cognitive disorders

Recent research has proposed that certain aspects of psychosis, as experienced in, e.g., schizophrenia (SCZ), but also aspects of other cognitive conditions, such as autism spectrum disorders (ASD) and synesthesia, can be related to a shattered sense of the notion of self. In this paper, our goal is to show that altered processing of self can be attributed to an abnormal functioning of cortico-striatal brain networks supporting, among other, one key human distinctive cognitive ability, namely cross-modality, which plays multiple roles in human cognition and language. Specifically, our hypothesis is that this cognitive mechanism sheds light both on some basic aspects of the minimal self and on some aspects related to higher forms of self, such as the narrative self. We further link the atypical functioning in these conditions to some recent evolutionary changes in our species, specifically, an atypical presentation of human self-domestication (HSD) features. In doing so, we also lean on previous work concerning the link between cognitive disorders and language evolution under the effects of HSD. We further show that this approach can unify both linguistic and non-linguistic symptoms of these conditions through deficits in the notion of self. Our considerations provide further support for the hypothesis that SCZ and ASD are diametrically opposed cognitive conditions, as well for the hypothesis that their etiology is associated with recent human evolution, leading to a deeper understanding of the causes and symptoms of these disorders, and providing new cues, which can be used for an earlier and more accurate diagnostics.
