Schonenberg + Jusyte 2014, presented 55 violent offenders with images of emotionally ambiguous facial expressions. When compared with non-aggressive matched control group violent offenders were likely to perceive images as angry + hostile. The roots of this behaviour may be apparent in childhood, Dodge + Frame 1982 showed children a video clip of an ambiguous provocation (intention was neither clearly hostile or accidental). Children who had been identified as aggressive + rejected prior to the study interpreted the situation as more hostile than those classed as non-aggressive and accepted.
