Regional variation of cloze probabilities for sentence contexts.
In 1980, Bloom and Fischler published a paper describing a set of sentence contexts (SCs) and their cloze probabilities (CPs). This material has subsequently been employed in numerous studies of linguistic processing. We sought to define the completion words and their CPs for Bloom and Fischler's sentences in an inner-city British population in order to establish reliable norms for subsequent studies in the U.K. One hundred and fifty incomplete SCs were presented to 73 volunteers. The CPs for each of the words used to complete the SCs were computed. We then compared the CPs from our sample with those from Bloom and Fischler. There were significant differences between CPs from each sample in 14% of the SCs analyzed (p < .01). Our data suggest that studies employing SCs and CPs may require locally defined norms if the test population differs substantially from the original one. The consequences of employing SCs and CPs to study linguistic processing without normalization are discussed.
