Note: Average measurements for the 300 probes in each condition are shown with standard deviation in parentheses. Acoustic measurements of WAVE files were recorded using Praat software (version 4.0.41) on Apple computers. Intensity levels are reported in dB SPL and pitch measurements in Hz. There were no differences between the six probe conditions in any acoustic measure during the four measurement windows (p’s > .20).
