Sato (2014) reported through three experiments (n = 10 for each) that the concept of time is distributed on our bodies and that associations are found between the right hand and the future and the left hand and the past. The present study replicated Sato’s experiment, and also added a condition in which only one hand was used, to examine whether associations with temporal concepts could also be found for the right and left fingers. The results showed that in Experiment 1 (n = 10), no associations with temporal concepts were found in either the two-handed or right-handed conditions, while in Experiment 2 (n = 20), which used twice the sample size, some associations with temporal concepts were found only in the two-handed condition. Furthermore, in Experiment 3 (n = 20), no associations with temporal concepts were found in either the two-hand or left-hand conditions. These results suggest that temporal concepts are not associated with fingers and that the association between the left and right hand may not be as robust as reported by Sato (2014).
