A comparison of oral and written english styles in african american students at different stages of writing development.

Purpose: The purpose of this investigation was to compare the rates of using African American English (AAE) grammatical features in spoken and written language at different points in literacy development. Based on Kroll's model (1981), a high degree of similarity in use between the modalities was expected at Grade 3, and lower similarity was expected at Grade 8.

Method: Spoken and written language samples were analyzed for the occurrence of 6 AAE morphosyntactic features.

Effects of digital vibrotactile speech feedback on overt stuttering frequency.

Fluency-enhancing speech feedback, originating from internally or externally generated sources via auditory or visual sensory modalities is not restricted to a specific sensory modality or signal origination. Research suggests that externally generated digital vibrotactile speech feedback serves as an effective fluency enhancer. The present purpose was to test the fluency-enhancing effects of self-generated digital vibrotactile speech feedback on stuttering frequency.

The effects of self-generated synchronous and asynchronous visual speech feedback on overt stuttering frequency.

Purpose: Relatively recent research documents that visual choral speech, which represents an externally generated form of synchronous visual speech feedback, significantly enhanced fluency in those who stutter. As a consequence, it was hypothesized that self-generated synchronous and asynchronous visual speech feedback would likewise enhance fluency. Therefore, the purpose of this study was to investigate the effects of self-generated visual feedback (i.
