Cultural influences on the concept of self is a very important topic for social cognitive neuroscientific exploration, as
yet, little if anything is known about this topic at the neural level. The present study investigates this problem by looking
at the Chinese culture's influence on the concept of self, in which the self includes mother. In Western cultures, self-referential
processing leads to a memory performance advantage over other forms of semantic processing including mother-referential, other-referential
and general semantic processing, and an advantage that is potentially localizable to the medial prefrontal cortex (MPFC).
In Chinese culture, however, the behavioral study showed that mother-referential processing was comparable with self-referential
processing in both memory performance and autonoetic awareness. The present study attempts to address whether similar neural
correlates (e.g. MPFC) are acting to facilitate both types of referencing. Participants judged trait adjectives under three
reference conditions of self, other and semantic processing in Experiment I, and a mother-reference condition replaced the
other-reference condition in Experiment II. The results showed that when compared to other, self-referential processing yielded
activations of MPFC and cingulate areas. However, when compared to mother, the activation of MPFC disappeared in self-referential
processing, which suggests that mother and self may have a common brain region in the MPFC and that the Chinese idea of self
includes mother.
