red. What does this tell you about the stimulus for this behaviour?​

Answer 1

Answer:

because human body response most to red colour means the cells in our eyes responds most to rred colour. but the aggressive behavior arivved because of some his own issue or family pressure at that time he must have seen red colour which has diverted his mind in different way of thinking. that's why his anger is making him rough and by seeing red he is remembering that event or thought.
