While reading or speaking, individuals break up sentences into "meaningful chunks." This is true of any individual with any language background. Failure to do so, in an L2 context, leads to idiosyncrasies, and may possibly create some comprehensibility problems. In this study, native and non-native speakers of English read an authentic text into a tape recorder; individual recordings were analysed in terms of intrasentential pauses where "that" clauses began. The places and duration of stops preceding and following "that" were identified and measured. Findings suggest that while pauses preceding "that" are much longer than following "that" in the production of native speakers, the pauses of Turkish speakers of English were found to be just the opposite. The findings of this research can be utilized in speaking and reading classes of English.
