Click to increase image sizeClick to decrease image size Notes1 The author and the editor wish to emphasize that the analyses of the data collected in the study described in this paper are still in a very preliminary stage and that some of the findings reported here may be altered with more detailed analysis. Nevertheless, because there is a great deal of current interest in questions about etiology in relation to psychopathy and because the research uses a unique sample in which genetic and environmental variables can be separated more satisfactorily than has previously been possible, it was considered important to publish this provisional report.
