Is it the case, therefore,that good and poor heartbeat perceivers focus on different parts of the hand and thus enhance SPSs perception at different anatomical segments of the hand? And if so, why? In light of the existing literature, it is difficult to conclude whether individuals with good and poor heartbeat perception focus on different hand segments. But some research showed that, compared with other parts of the hand, the processing of tactile targets delivered in the center of the palm is facilitated as early as 1000 ms after attention orienting [20].
