abstract = {The mental representations of space, time, and number
magnitude are inherently linked. The right posterior
parietal cortex (PPC) has been suggested to contain a
general magnitude system that underlies the overlap between
various perceptual dimensions. However, comparative studies
including spatial, temporal, and numerical dimensions are
missing. In a unified paradigm, we compared the impact of
right PPC inhibition on associations with spatial response
codes (i.e., Simon, SNARC, and STARC effects) and on
congruency effects between space, time, and numbers.
Prolonged cortical inhibition was induced by continuous
theta-burst stimulation (cTBS), a protocol for transcranial
magnetic stimulation (TMS), at the right intraparietal
sulcus (IPS). Our results show that congruency effects, but
not response code associations, are affected by right PPC
inhibition, indicating different neuronal mechanisms
underlying these effects. Furthermore, the results
demonstrate that interactions between space and time
perception are reflected in congruency effects, but not in
an association between time and spatial response codes.
Taken together, these results implicate that the congruency
between purely perceptual dimensions is processed in PPC
areas along the IPS, while the congruency between percepts
and behavioral responses is independent of this region.},
