“…Brébion [44] suggested that selective attention disorder in schizophrenia patients might reduce reality-differentiating capacity, leading to hallucinations and delusions. Besides, another study revealed a positive correlation between negative symptoms severity and attention disorder [45]. In addition, some studies also showed that the attention disorder found in schizophrenia patients might exhibit disease specificity to a certain degree [46][47].…”

“…Research in the field of schizophrenia indicates that negative symptoms are strongly associated to cognitive impairments, even if the precise nature of their relationship is still not fully established (Harvey et al, 2006). More specifically, negative symptoms have been associated with various cognitive domains, such as processing speed (Lipkovich et al, 2009;McDowd et al, 2011), working memory (Kebir & Tabbane, 2008;O'Gráda et al, 2009;Szendi et al, 2006), long-term memory (McDowd et al, 2011), executive functioning (Clark et al, 2010;Lewandowski et al, 2011), and attention (Sanz et al, 2012;Tsai et al, 2010). On the opposite, positive symptoms are thought to be largely independent of cognitive functioning (e.g.…”

“…In terms of clinical symptomatology, cognitive deficits are proposed to be more closely associated with negative and disorganised aspects of psychosis compared with positive symptoms (Bora and Murray, 2013;Dominguez et al, 2009). Attention, psychomotor speed and verbal learning in particular have been found to correlate with negative symptoms in schizophrenia (August et al, 2012;Bora and Murray, 2013;O'Gráda et al, 2009), while disorganised symptoms were related to lower verbal and visual learning, processing speed and social cognition (August et al, 2012;Flaum et al, 2000). Whether or not cognitive performance differs significantly between subtypes of psychosis, such as affective and non-affective subtypes, has not been determined conclusively.…”
