“…This is in line with a processing approach to agrammatism, in which it is argued that agrammatic performance goes up when the processing load is reduced (e.g. Sahraoui & Nespoulous, 2012). Grammatical gender in Danish is generally not semantically meaningful, and producing it erroneously does not have communicative consequences.…”

The production of grammatical and lexical determiners in Broca's aphasia Determiner production is a testing ground for theories of Broca's aphasia and agrammatic speech. On one type of theory, determiner production is impaired in so far as determiners are grammatical items. On another type of theory, determiner production is impaired because determiners depend on verbs for case-assignment. These two types of theories are mutually compatible, but in recent years, research on determiner production has focused on the second type. In order to test the first type, an experiment was carried out which contrasted the production of Danish grammatical determiners (indefinite articles) and lexical ones (numerals) in 5 speakers diagnosed with Broca's aphasia and 4 nonbrain-damaged controls. The results strongly support the first type of theories: 1) in agrammatic speech, only grammatical determiners were omitted to an extent which differs from omission rates in the speech of the controls; 2) substitutions of grammatical agreement markers were found only in agrammatic speech.

“…The same participants were able to produce definite articles in a picture description taska task which is more constrained than spontaneous speech, and in which agrammatic speakers have previously been found to perform better (Sahraoui & Nespoulous, 2012;Salis & Edwards, 2004).…”

“…morpho-syntactic simplifications) may be due to universal strategies that emerge from the need to compensate for a difficulty in retrieving specific linguistic information (i.e. accessing morphemes) at the formulation level or from a deeper impairment at the conceptualization level (see also Klein & Perdue, 1997;Kolk 2006;Sahraoui & Nespoulous 2012), but it is difficult to tease these two levels of processing apart. Differences in compensation (e.g., Path lexicalization in French vs. grammaticalization in English) rather reflect the strong impact of language on encoding processes irrespective of competence or syndromes.…”

Languages show differences in how they encode motion in discourse: Verbframed languages lexicalize Path in the verb, leaving Manner peripheral or implicit; Satellite-framed languages lexicalize Manner together with Path adjuncts. The present study investigates: 1) the extent to which such typological constraints affect the verbalizations of second language learners (English learners of French) and of aphasic speakers (English and French speakers with agrammatism) -who typically show dissociations between lexical and syntactic knowledge -in comparison to controls (English and French native speakers); as well as 2) the role of language-independent factors (level of acquisition, syndrome type). Despite some similarities between learners and speakers with aphasia due to language-independent factors, the findings suggest typologically constrained verbalizations in all groups, as well as diverging strategies that may reflect distinct underlying conceptualization processes.

“…Since the early 20 th century (Lashley, 1929;Goldstein, 1939;Luria, 1970Luria, [1947), many researchers and clinicians have been interested in the concept of compensatory or adaptive strategies, which are assumed to allow aphasic subjects to overcome communicative difficulties (Penn, 1987;Bertoni, Stoffel, & Weniger, 1991;Kolk & Heeschen, 1990, 1996Simmons-Mackie & Damico, 1997;Oelschlaeger & Damico, 1998;Heeschen & Schegloff, 1999, 2003Laakso & Klippi, 1999;Wilkinson, Beeke, & Maxim, 2003;Nespoulous & Virbel, 2004;Simmons-Mackie, Kearns, & Potechin, 2005;Wilkinson, Gower, Beeke, & Maxim, 2007;Salis & Edwards, 2004;Beeke, Wilkinson, & Maxim, 2009;Sahraoui & Nespoulous, 2012;Nespoulous, Baqué, Rosas, Marczyk, & Estrada, 2013;Rhys, Ulbrich, & Ordin, 2013). Within compensation and/or adaptation frameworks there are two main assumptions: 1) compensatory adaptation is pervasive in both ordered and disordered communication (Nespoulous & Virbel, 2004;Perkins, 2007) and occurs when various underlying semiotic, cognitive and sensorimotor capacities both within and between individuals become inefficient for interpersonal communication; and 2) disordered speech output (in our case, aphasic speech output) is not the direct reflection of the underlying linguistic impairments but rather the result of strategic choices developed in order to face these disorders and to improve communicative effectiveness.…”

Lexical stress contrast marking in fluent and non-fluent aphasia in Spanish: The relationship between acoustic cues and compensatory strategies

This study sought to investigate stress production in Spanish by patients with Broca's (BA) and conduction aphasia (CA) as compared to controls. Our objectives were to assess whether: a) there were many abnormal acoustic correlates of stress as produced by patients, b) these abnormalities had a phonetic component and c) ability for articulatory compensation for stress marking was preserved. The results showed abnormal acoustic values in both BA and CA's productions, affecting not only duration but also F0 and intensity cues, and an interaction effect of stress pattern and duration on intensity cubes in BA, but not in CA or controls. The results are interpreted as deriving from two different underlying phenomena: in BA, a compensatory use of intensity as a stress cue in order to avoid 'equal stress'; in CA, related to either a 'subtle phonetic deficit' involving abnormal stress acoustic cue-processing or to 'clear-speech' effects.
