The Relationship between Hypnotizability and Speed of Closure. Technical Report 6.
Lohman, David F.
A report by Crawford found substantial correlations between hypnotizability and various speed-of-closure measures. An attempt to replicate these correlations on the same population of university undergraduates in the present study yielded markedly lower correlations. Nonproportional sampling techniques may have spuriously inflated the earlier reported correlations. Subsequent attempts to correct these correlations for the biases introduced by nonproportional 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, and has implications for correlational research using nonproportional or extreme groups designs. It appears that there is a relationship between hypnotizability and speed of closure, though not of the magnititude suggested by Crawford. (Author/VT)
