It has come to the attention of the authors that the article "Basic Auditory Processing Skills and Phonological Awareness in Low-IQ Readers and Typically Developing Controls," published in Scientific Studies of Reading 15(3), 211-243, describes an older version of the Frequency ABABA task (Thomson & Goswami, 2008) which used stimuli that were 25 ms long. In fact, in the task used by Kuppen et al., two sequences of 5 tones were presented with ISIs of 50 ms, and each tone was 200 ms long (500 Hz) with a 50 ms rise time and 50 ms fall time, as described in the ABABA Frequency task of Wang, Huss, Hämäläinen, and Goswami (in press). The target sounds changed along a logarithmic continuum of 40 stimuli ranging from 500 Hz to 514.6 Hz. This does not affect the data reported by Kuppen et al., which used the conversion metric for the correct 200 ms Frequency ABABA task. The authors apologize for this error.
