Abstract
In this paper we report the outcomes of two attempts to correlate the Zenhausern Preference Questionnaire (PT) with the Polarity Questionnaire (PQ). Across two laboratories we consistently found no correlation between these two scales. Our findings are consistent with a previous attempt to validate the PQ (Genovese, 2005). We conclude that researchers attempting to use the PQ should take note of this validity question.
Notes
1In a later paper Morton (Citation2003b) did not test the correlation between the PQ and the PT but reported that both significantly correlated with a third hemispheric measure introduced in the study.
2Two participants were excluded from the analysis because they failed to complete all of the items in each of the measures. Thus 108 participants were included in the final analysis.
