Abstract
People rely on various frames of reference (FORs), such as
egocentric (EFOR) and intrinsic (IFOR), to represent spatial information. The
present study examined electroencephalogram profiles on a two-cannon task, which
could regulate the conflict of IFOR-IFOR (red cannon, blue cannon) and IFOR-EFOR
(target cannon, observer), to elucidate the brain mechanisms of FOR conflict
processing by using event-related potentials (ERPs). Results showed that both of
the conflicts occurred in the reaction time (RT) and there was an interaction
between them. ERP results showed more negative amplitudes on N2 (276-326 ms) and
P3 (396-726 ms) for IFOR-IFOR conflict of the 180° cannon angle condition
and EFOR-IFOR conflict of the target cannon point-down condition. What’s
more, there was also an interaction between these two conflicts on the P3
amplitudes (561-726 ms). In summary, our findings shed new light on the
domain-specific conflict monitoring and domain-general executive control for the
IFOR-IFOR and EFOR-IFOR conflicts.
