“…The Brief Psychiatric Rating Scale (BPRS) 41 was administered to all subjects and a confirmatory factor analysis (CFA) established the symptom structure used to characterize the sample. 42 The 5 factors extracted were labeled disorganization, anergia, thought disorder, affect and activity. Symptom factors were not mutually exclusive.…”

“…Previous work, including our own, has established that cognitive, social cognitive, and symptom indicators among deaf people with schizophrenia are generally similar to those of hearing people with schizophrenia, with a few notable exceptions. 42,[46][47][48] Symptom profiles previously established in the current sample by a CFA of the BPRS (table 2) were compared with context processing variables. Consistent with past literature, the disorganized syndrome was the only significant correlate of a weakened illusion effect.…”

Visual Context Processing Deficits in Schizophrenia: Effects of Deafness and Disorganization

Visual illusions allow for strong tests of perceptual functioning. Perceptual impairments can produce superior task performance on certain tasks (i.e., more veridical perception), thereby avoiding generalized deficit confounds while tapping mechanisms that are largely outside of conscious control. Using a task based on the Ebbinghaus illusion, a perceptual phenomenon where the perceived size of a central target object is affected by the size of surrounding inducers, we tested hypotheses related to visual integration in deaf (n = 31) and hearing (n = 34) patients with schizophrenia. In past studies, psychiatrically healthy samples displayed increased visual integration relative to schizophrenia samples and thus were less able to correctly judge target sizes. Deafness, and especially the use of sign language, leads to heightened sensitivity to peripheral visual cues and increased sensitivity to visual context. Therefore, relative to hearing subjects, deaf subjects were expected to display increased context sensitivity (ie, a more normal illusion effect as evidenced by a decreased ability to correctly judge central target sizes). Confirming the hypothesis, deaf signers were significantly more sensitive to the illusion than nonsigning hearing patients. Moreover, an earlier age of sign language acquisition, higher levels of linguistic ability, and shorter illness duration were significantly related to increased context sensitivity. As predicted, disorganization was associated with reduced context sensitivity for all subjects. The primary implications of these data are that perceptual organization impairment in schizophrenia is plastic and that it is related to a broader failure in coordinating cognitive activity.

“…However, sign language communication or text-only communication is not as low-costly or efficient as natural language communication. But even so, the auditory disabled with mental disease can still be efficient in some kinds of thinking pattern by sign language training [8]. Similar to common people, they still have most of the verbal thinking in their minds, and words as well as symbols such as gestures do not have the same tremendous impairment in the efficiency of thinking in the brain as they do in communicating.…”

The First Nature of Language

The first nature of language function is often considered to be communication. But with the rise of cognitive linguistics, whether the primary function of language is externalized communication or internalized thinking has been re-examined. This paper focused on what is the first function of language, and argued that the thinking function should remain the top priority. Based on theories of generative grammar from Noam Chomsky, it redefines the key concepts of language, thinking, and communication, discusses the superiority of language for thinking and the shortcomings of language for communication, and reveals the direction of language evolution by natural selection, and compile a series of evidence to justify the top status of thinking function by comparing the common peoples thinking ability and the auditory disableds thinking ability. Besides, another possible communicative pattern, direct brain-to-brain communication (DBBC) was also introduced to prove there might emerge a better way for communication. It is hoped that this will paint a possible picture of the development of language function science and provide an organic extension for the subsequent discovery of language function. At the end the paper finds out the first nature of thinking is plausible and tangible, conforming to the evolutionary tendency of human language. More researches are expected to provide more direct proofs approving the arguments.
