Admittedly, they have described a more idealised basilect.
The present data suggest that both basilect-dominant and acrolect-dominant speakers show stylistic variation.
This suggests that spectral distinctiveness may not play as prominent a role in vowel quality contrasts for basilect-dominant speakers as it does for acrolect-dominant ones.
A "child-language" definition of the notions of acrolect, mesolect, and basilect must be different, to be sure, from an adult-language approach to these concepts.
Interestingly, the trend noted here (males producing more downgliding forms than females) was not maintained in the picture task for the basilect-dominant speakers.
This finding runs counter to the expectation that picture task data would provide responses similar to word list data for basilect-dominant speakers.
The reason for this is that these are residual forms of the basilect (more characteristic of the pre-bas, which has over tones of being "broken").
By comparison, male and female basilect-dominant speakers showed a great deal more downgliding variants in their conversational data than in their word list data.
