“…Miscomprehension of figurative meanings by schizophrenic patients is a phenomenon already mentioned in historical descriptions (Hadlich, 1931 ; Goldstein, 1939 ; Kasanin, 1944 ; Elmore and Gorham, 1957 ). The deficit includes all subtypes of figurative language including proverbs (Brattemo, 1962 ; Rapp et al, 2014 ), metaphors (Langdon et al, 2002 ; Schneider et al, 2015 ; Bambini et al, 2016a ), irony (Sparks et al, 2010 ; Rapp et al, 2013 , 2014 ), and idioms (Titone et al, 2002 ; Schettino et al, 2010 ; Sela et al, 2015 ).…”

Miscomprehension of nonliteral (“figurative”) language like metaphors, proverbs, idioms, and ironic expressions by patients with schizophrenia is a phenomenon mentioned already in historical psychiatric descriptions. However, it was only recently that studies did differentiate between novel and conventional metaphors, a factor that is known to influence the difficulty of comprehension in healthy subjects. Further, familiarity with stimuli is an important factor for comprehension, which was not recommended in utmost previous studies. In this study, 23 patients with DSM IV schizophrenia and 19 healthy control subjects performed a newly-developed German metaphor comprehension test with three types of stimuli: novel metaphors, conventional German metaphors, and meaningless statements. During the test procedure, participants indicated familiarity with the stimulus and then matched the meaning with one out of four given alternatives. Familiarity rankings did not significantly differ between patients and control subjects. However, on descriptive level, there was a tendency for healthy controls to be more familiar with conventional metaphors than schizophrenic patients. Further, comprehension of conventional and novel metaphors differed significantly between the groups, with higher performance in healthy controls. Considering only those metaphors that had been ranked as familiar, patients only revealed significant lower performance opposed to controls regarding novel metaphors, while they did not differ in conventional metaphors. Taken together, the results indicate that patients with schizophrenia might show an altered way of comprehension in novel metaphors, leading to more misunderstandings. However, their previously reported impairments in conventional metaphors might rather be due to a lack of familiarity with the stimuli—making conventional metaphors to novel metaphors in the individual case.

Functional near-infrared spectroscopy (fNIRS), a growing neuroimaging modality, has been utilized over the past few decades to understand the neuronal behavior in the brain. The technique has been used to assess the brain hemodynamics of impaired cohorts as well as able-bodied. Neuroimaging is a critical technique for patients with impaired cognitive or motor behaviors. The portable nature of the fNIRS system is suitable for frequent monitoring of the patients who exhibit impaired brain activity. This study comprehensively reviews brain-impaired patients: The studies involving patient populations and the diseases discussed in more than 10 works are included. Eleven diseases examined in this paper include autism spectrum disorder, attention-deficit hyperactivity disorder, epilepsy, depressive disorders, anxiety and panic disorder, schizophrenia, mild cognitive impairment, Alzheimer’s disease, Parkinson’s disease, stroke, and traumatic brain injury. For each disease, the tasks used for examination, fNIRS variables, and significant findings on the impairment are discussed. The channel configurations and the regions of interest are also outlined. Detecting the occurrence of symptoms at an earlier stage is vital for better rehabilitation and faster recovery. This paper illustrates the usability of fNIRS for early detection of impairment and the usefulness in monitoring the rehabilitation process. Finally, the limitations of the current fNIRS systems (i.e., nonexistence of a standard method and the lack of well-established features for classification) and future research directions are discussed. The authors hope that the findings in this paper would lead to advanced breakthrough discoveries in the fNIRS field in the future.

Schneider et al (2015) used ERPs-NIRs technique to look into SPs' metaphor comprehension.

Figurative Language Comprehension in Schizophrenia and Its Neural Basis

Schizophrenia is a kind of serious mental disease, which may cause major impairment in patients’ social-cognitive ability. It has been found that pragmatic ability in schizophrenic patients is often impaired, especially for figurative language comprehension. Figurative language refers to irony, metaphor, idiom and the like. People with schizophrenia tend to interpret figurative language as its literal meaning, which is called schizophrenic concretism. By reviewing extant literature, we found that the literature concerning this topic mainly consists of two parts: behavioral studies and brain-imaging studies. The behavioral studies mainly explore how clinical factors and cognitive ability have an impact on figurative language comprehension. Brain-imaging studies mainly discuss hemisphere lateralization in schizophrenia and whether theory of mind network in schizophrenic patients is different from that of normal groups. We conclude that future research should further explore the relationship among figurative language comprehension, cognitive ability and clinical factors, and also reveal related neural mechanism.
