Tabletop Versus Microcomputer-Assisted Speech Management: Response Evocation Phase

This is the third in a series of studies on the use of microcomputers with speech-delayed children. Two repeated-measures designs (n=15) and five case studies were completed to compare tabletop management at early and late stages of the response development phase with two comparable, computer-assisted drill-and-practice activities. Discrimination of correct articulatory responses was mediated by the clinician in all modes, rather than by speech recognition hardware, but all contingent reinforcement in the computer modes was presented by animation graphics. The two computer modes were identical except for the addition of fantasy involvement in one of the modes. Findings indicated that the three modes of intervention were equally effective, efficient, and engaging. Subject-level analyses suggested that microcomputer software has excellent potential to engage children in drill-and-practice for late-phase response evocation, when the target sound is stimulable, but limited usefulness with young children at early-phase response evocation, when specific articulatory behaviors need to be cued. Discussion considers learning, child, and hardware/software factors in microcomputer-assisted speech management.
