✦ Synopsis

The present study examined the validity of the Preference Test (PT), a questionnaire that intends to measure the extent to which subjects rely on right-hemisphere and left-hemisphere cognitions. Normal subjects (N ϭ 20) completed the PT and were then assigned to a group with a relatively strong preference for left-hemisphere cognitions or a group with a relatively strong preference for right-hemisphere cognitions. Next, background EEG was recorded. Subjects with a preference for right-hemisphere cognitions were found to display relatively more a power over the left than over the right frontal areas, compared to subjects with a preference for left-hemisphere cognitions. This finding provides partial support for the validity of the PT.

The scores of three aggression parameters in a standard-opponent test correlated significantly with individual androgen concentrations measured in tissue as well as in blood samples taken immediately after the test (bites: r = + .62/+ .82, threats: r = + .75/ + .70, latency: r = -.66/ -S3). If the t
