A team of biomedical engineers has mapped the bodily reactions to emotions in 700 individualsand found that patterns were the same, whether the candidate was from Western Europe or East Asia. The study, carried out by a team from Finland, relies on descriptive feedback provided by candidates from Finland, Sweden and Taiwan. Brain mapping or external sensors could have been used to measure neurological changes and physiological outputs such as sweat and body temperature, but by providing subjects with two silhouettes of the human body and asking them to point out exactly where they felt activity increasing or decreasing, the team could gather intimate data otherwise impossible. It does, of course, mean the study relies on candidates self-assessing accurately and without bias. However, the correlations that arose across cultural and linguistic boundaries provide a strong argument that the subjects did indeed report without bias.
