biological - theorists in this field will try to explain aggression through description of enzymes and certain body components that trigger anger and violence. As their field suggests, theorists will try to explain aggression with medical and scientific definitions and terms.
behavioral - as the field says, based on a person's attitudes and actions that lead to aggression. I guess some behavioral explanations would be pupils dilating, breathing increase, etc.
cognitive - this means mental state of mind. what mentality triggers aggression and such i think. what mood and feeling you get/need to lead to violence and anger.
psychodynamic -
Definition: Psychology.any clinical approach to personality, as Freud's, that sees personality as the result of a dynamic interplay of conscious and unconscious factors.
based on the definition, i would guess it has to do with the person's personality, so its related to behavioral and cognitive field imo. what kind of personality is prone to aggression and whatnot.
just think them all through. should be pretty straight forward if you know what the question is asking you.
