Taylor Aggression Paradigm
aggression
Reactive aggression was measured by using the TAP task (The TAP task comprised two blocks. Each block contained 20 rounds, with half against a low-provoking opponent (labeled as ‘Q’) and the other half against a high-provoking opponent (labeled as ‘W’). The sequence of rounds in each block was pre-determined by a computer program such that no opponent would appear more than three times in a row. Each trial started with informing the participant that one opponent had been randomly selected (see (A) Trial timing for the TAP. (B) Trial timing for the RIT.The punishment selected by the opponent and the outcome of the competition were pre-determined by an algorithm such that the probability of loss against either the low- or high-provoking opponents was 50% and the percentages of high punishment chosen by the high- and low-provoking opponents were 80% and 20%, respectively.
