The purpose of this study was to investigate the accuracy and reliability of observational data on spontaneous slips of the tongue. Usually slips are jotted down immediately after being heard but there is no possibility of re-examining the correctness or completeness of this transcription. Four listeners noted down slips in this way ("on-line") and their transcriptions were compared with a transcription obtained by repeated listening to the same tape-recorded discussion. The one-line listeners recorded only about one-third as many slips as were detected by repeated listening, and, even so, about half the items noted as slips proved erroneous. There were also considerable differences between the individual listeners regarding the error units.
本研究的目的是调查关于自发口误观察数据的准确性和可靠性。通常口误在被听到后会立即记录下来，但没有可能重新检查这种记录的正确性或完整性。四名听众以这种方式（“在线”）记录口误，他们的记录与通过反复聆听同一盘录音讨论获得的记录进行比较。在线听众记录的口误数量仅为反复聆听检测到的口误数量的三分之一左右，即便如此，被记录为口误的项目中约有一半被证明是错误的。在错误单元方面，各个听众之间也存在相当大的差异。
