“…Tasks did not include counting, which is the automatic speech behaviour most frequently observed in aphasia, and is most commonly used in intraoperative cortical mapping for speech. In a preliminary report using PET imaging, differences in brain activation patterns for counting compared with story telling were described (Blank et al 2001). Earlier studies of cerebral blood flow using SPECT methodology also associated right hemisphere activation (as well as left) with automatic speech (Larsen et al 1978, Ingvar 1983, Ryding et al 1987.…”

Although interest in the language sciences was previously focused on newly created sentences, more recently much attention has turned to the importance of formulaic expressions in normal and disordered communication. Also referred to as formulaic expressions and made up of speech formulas, idioms, expletives, serial and memorized speech, slang, sayings, clichés, and conventional expressions, non-propositional language forms a large proportion of every speaker's competence, and may be differentially disturbed in neurological disorders. This review aims to examine non-propositional speech with respect to linguistic descriptions, psycholinguistic experiments, sociolinguistic studies, child language development, clinical language disorders, and neurological studies. Evidence from numerous sources reveals differentiated and specialized roles for novel and formulaic verbal functions, and suggests that generation of novel sentences and management of prefabricated expressions represent two legitimate and separable processes in language behaviour. A preliminary model of language behaviour that encompasses unitary and compositional properties and their integration in everyday language use is proposed. Integration and synchronizing of two disparate processes in language behaviour, formulaic and novel, characterizes normal communicative function and contributes to creativity in language. This dichotomy is supported by studies arising from other disciplines in neurology and psychology. Further studies are necessary to determine in what ways the various categories of formulaic expressions are related, and how these categories are processed by the brain. Better understanding of how non-propositional categories of speech are stored and processed in the brain can lead to better informed treatment strategies in language disorders.

“…Tasks did not include counting, which is the automatic speech behavior most frequently preserved in aphasia. In a preliminary report using PET imaging, differences in brain activation patterns for counting compared with storytelling were described (Blank, Scott, and Wise 2001). A later report addressing the same question indicated extensive bilateral activation for propositional and nonpropositional tasks alike, with no differences in brain sites between speech modes (Blank, Scott, Murphy, Warburton, and Wise 2002).…”
