No evidence for the influence of head-heart conceptual metaphor on moral decision making and personality

In English, head is associated with rationality and logic, whereas heart is related to feeling and emotionality. In Chinese, these head- and heart-related metaphors also exist. Could these head- and heart-related conceptual metaphors influence people's moral decision-making and personality? This seems so based on the previous findings that (a) simply pointing an index finger to heart (versus head) position caused participants to produce more emotional responses in a moral decision task, and (b) participants who believed themselves to be heart locators, relative to those who regarded themselves as head locators, scored higher in affect intensity, femininity, and intimacy related activities. The current study attempted to replicate these findings, following the same design and procedure of previous work, with Chinese participants from Hong Kong and Chinese mainland. In Experiments 1a and 1b, 203 participants performed the moral decision task on dilemmas with their index fingers pointing to head or heart. In Experiments 2a and 2b, 304 participants completed the scales of self-location, affective intensity, femininity, and intimacy related activities. In these high-powered experiments, we failed to replicate the findings of previous work. Bayesian analyses further showed that no head- and heart-related conceptual metaphor effect was likely to occur. Potential reasons for our inconsistent results with those of previous studies and the implications of our current findings were discussed.
