Abstract:

Many trait theorists have argued against the artificial separation of ability and personality constructs. Hilgard contends that hypnotizability is a personality construct. Until recently, however, attempts to relate hypnotizability to other personal characteristics have yielded negative or inconclusive results. Thus, a report by Crawford of substantial correlations between hypnotizability and various speed-of-closure ability measures signalled an important breakthrough. An attempt to replicate those correlations on the same population in the present study yielded markedly lower correlations. It is argued that non-proportional sampling techniques spuriously inflated the earlier reported correlations. Subsequent attempts to correct these correlations for the biases introduced by non-proportional sampling led to the development of a new technique to correct an inflated correlation. This procedure empirically modifies the distribution of scores to reflect the normative distribution. Implications of these techniques for correlational research using nonproportional or extreme groups designs are discussed.
