Relationship between right/left hippocampal laterality and StP scores. Individuals where the right hemisphere may be approaching symmetry with the left or overtaking it in terms of size have higher scores on the Sensitivity to Punishment scale suggestive of a more hyperactive Behavioural Inhibition System. Hippocampus laterality ratio = (right - left hippocampal volume)/total hippocampal volume; a zero score would reflect a perfectly symmetric hippocampus.
