Comprehension of concrete and abstract words in semantic variant primary progressive aphasia and Alzheimer's disease: A behavioral and neuroimaging study
2017, Brain and LanguageCitation Excerpt :Even though it is evident that concrete and abstract word comprehension relies on a common distributed neural network, it is possible that differences in the representations of abstract and concrete words may be underpinned by at least partly different neural regions, such as suggested by clinical dissociations (for review, see Shallice & Cooper, 2013). For instance, aphasic patients with frontal or temporoparietal lesions have been found to present with specific difficulties in processing abstract words, while an anomic aphasic patient with occipital lesions exhibited difficulty in concrete word processing (Martensson et al., 2011; Tyler, Ostrin, Cooke, & Moss, 1995). Other studies also showed that semantic aphasia patients who suffered prefrontal and/or temporoparietal infarction show deregulated semantic cognition across different modalities, i.e. they had difficulties in semantic tasks due to a failure of executive control (Corbett, Jefferies, & Ralph, 2011; Jefferies & Lambon Ralph, 2006).
Deficit-lesion correlations in syntactic comprehension in aphasia
2016, Brain and LanguageCitation Excerpt :As noted, end-of-sentence performance involves memory for sentence meaning (and possibly form) and is distant from the incremental processing of syntactic structure. Studies using word monitoring (Tyler, 1985; Tyler, Ostrin, Cooke, & Moss, 1995), on-line anomaly detection (Shankweiler, Crain, Gorell, & Tuller, 1989), cross modal priming (Balogh, Zurif, Prather, Swinney, & Finkel, 1998; Burkhardt, Piñango, & Wong, 2003; Love, Swinney, Walenski, & Zurif, 2008; Love, Swinney, & Zurif, 2001), self-paced listening (Caplan & Waters, 2003; Caplan, Waters, DeDe, Michaud, & Reddy, 2007) and eye tracking in sentence picture matching (Hanne, Sekerina, Vasishth, Burchert, & De Bleser, 2011; Meyer, Mack, & Thompson, 2012) and in the visual world paradigm (Dickey, Choy, & Thompson, 2007; Dickey & Thompson, 2009; Thompson & Choy, 2009) have provided empirical data relevant to mechanisms that might underlie these disorders. Hypotheses regarding the mechanisms that produce syntactic comprehension disorders that have emerged from on-line studies include the ideas that the deficit consists of slowed lexical processing (Balogh et al., 1998; Love et al., 2001, 2008), slowed processing of syntactic structure (Burkhardt et al., 2003), slowed integration of lexical and syntactic information (Meyer et al., 2012), and excessive sensitivity to meanings derived from sources other than parsing and interpretation (Caplan, 2015).
Neurocognitive dimensions of lexical complexity in Polish
2012, Brain and LanguageCitation Excerpt :It is argued that this left perisylvian network handles the processing of regularly inflected words (e.g. past tense or plural in English) that can be decomposed into stems and affixes, and are not stored as full forms. However, even very extensive damage to the left hemisphere can leave patients with substantial language comprehension abilities still intact, ranging from the ability to recognise simple spoken words to good comprehension of semantically predictable full sentences (Hagoort, 1997; Longworth, Marslen-Wilson, Randall, & Tyler, 2005; Tyler, Ostrin, Cooke, & Moss, 1995; Tyler et al., 2002, 2011). This evidence has led to the proposal that two distinct but interdependent processing networks are involved in normal language comprehension – a distributed bilateral system supporting general perceptual and cognitive processing, and a specialised left-lateralised system responsible for processing specifically linguistic features.
The role of Broca's area in regular past-tense morphology: An event-related potential study
2011, NeuropsychologiaCitation Excerpt :For instance, the LIFG has been implicated in two-word semantic priming designs only when the interval between prime and target is relatively long (e.g., 1000 ms), arguably permitting strategic retrieval in addition to automatic lexical activation (Gold et al., 2006). This finding echoes an earlier debate in the patient literature concerning whether the performance of Broca's aphasics in these tasks is better explained in terms of altered automatic or controlled processes (see Hagoort, 1997; Milberg, Blumstein, Katz, Gershberg, & Brown, 1995; Tyler, Ostrin, Cooke, & Moss, 1995). The notion of controlled retrieval is also particularly relevant for the role of Broca's area in the past-tense production task described in the Introduction; Broca's area is recruited for the production of both regular and irregular past tenses, and especially so for irregulars.
