To determine the effect of subject self‐selection on the alpha‐hypnotizability correlation, the correlations between volunteer and invited subject groups were compared. For 8 volunteers the correlation between baseline eyes‐closed occipital alpha and the Harvard Group Scale of Hypnotic Susceptibility score was r =.72; for 12 invited subjects, that correlation was r =‐.02. The significant difference in these correlations gives support to a previously published paper which hypothesized, on the basis of a literature review, that sampling modifications generated by subject self‐selection were responsible for the occurrence of significant alpha‐hypnotizability correlations.
