This inquiry investigated tone use among Yoruba-speaking adults recovering from an aphasic insult/attack initiated by a cerebral vascular accident (CVA), otherwise known as a stroke. In pursuing the aim of the study, the research was guided by three research questions, namely, do Yoruba-speaking aphasic adults have the perceptual ability to perceive tone in the language; can Yoruba-speaking aphasic adults differentiate between the three lexical tones in the language; and which of lexical tones do Yoruba speaking aphasic adults find difficult to perceive? The study drew upon the theoretical and analytical scope of the autosegmental approach and a constructivist methodology paradigm inspired by a descriptive research design that used the qualitative approach. Data elicited from purposively sampled informants via structured interviews involving two groups of participants three aphasic Yoruba individuals and three Yoruba non-aphasic individuals in Nigeria. The purposive sampling was premised on informants’ dialectal proficiency, availability and diversity, and occurrence of CVA (stroke). The aphasic subjects were identified with the initials AB, CD and EF to conform to confidentiality etiquette in clinical linguistics. For ethical consideration, the informants were required to fill in a consent form before eliciting data from them. Once that was done, the aphasics were availed 100 words from the combined Swadesh 200 and Ibadan 400 wordlist of essential and cultural items, recorded by the non-aphasic individuals who speak Yoruba as their first language, to identify which tones they perceive. The data elicited was analysed using the perceptual approach in which the recorded data was listened to several times to discover if adult Yoruba speakers that are aphasic were still able to recognise the high ( ́), mid ( ̄) and low tone (̀ ) in words. The findings reviewed that Yoruba aphasics have diverse perceptual abilities of tone. Furthermore, it was established that Yoruba aphasics displayed varying deficiencies in differentiating the three lexical tones of Yoruba. Of the three lexical tones (H, M and L), the unmarked M tone was consistent, while the H and L tones had varying perceptual outcomes among the CVA-aphasics. The implication of the finding is that tone recoveries among CVA-aphasics is never the same and, therefore, calls for various linguistic therapies according to each CVA-aphasic case.

“…Overall, the past and present time reference dissociation has been demonstrated in many languages (English and Turkish: Bastiaanse et al, 2011;Russian: Dragoy andBastiaanse, 2013 (Dutch: Bastiaanse, 2008;Bos and Bastiaanse, 2014;Spanish and Catalan: Martínez-Ferreiro and Bastiaanse, 2013; Korean: Lee et al, 2013). Bastiaanse et al (2011) and Bastiaanse (2013) capture the reason for this dissociation in the Past Discourse Linking Hypothesis (PADILIH), which claims that past time reference, whether expressed through tense and/or aspectual verb inflection, is selectively impaired because it requires discourselinking. According to the PADILIH, past time reference requires a link between the time of speaking the event time, since they do not coincide, whereas for reference to the present, the time of speaking coincides with the time of the event, and hence, no discourse linking is required.…”

“…We argue that this is the case when a violation is caused by a past verb. The Past Discourse Linking Hypothesis (PADILIH: Bastiaanse, 2013;Bastiaanse et al, 2011) claims that past time reference, whether expressed through tense and/or aspectual verb inflection requires discourse-linking. According to the PADILIH, past time reference requires a link between the time of speaking the event time, since they do not coincide, whereas for reference to the present, the time of speaking coincides with the time of the event, and hence, no discourse linking is required.…”

Previous electrophysiological studies that have examined temporal agreement violations in (Indo-European) languages that use grammatical affixes to mark time reference, have found a Left Anterior Negativity (LAN) and/or P600 ERP components, reflecting morpho-syntactic and syntactic processing, respectively. The current study investigates the electrophysiological processing of temporal relations in an African language (Akan) that uses grammatical tone, rather than morphological inflection, for time reference. Twenty-four native speakers of Akan listened to sentences with time reference violations. Our results demonstrate that a violation of a present context by a past verb yields a P600 time-locked to the verb. There was no such effect when a past context was violated by a present verb. In conclusion, while there are similarities in both Akan and Indo-European languages, as far as the modulation of the P600 effect is concerned, the nature of this effect seems to be different for these languages.
