Hello, SPM users and experts!
I used the PEB method to determine the group-mean strength of each modulatory connection (commonalities) and identify which connectivity contributed to the individual differences in RT amongst participants.
The ACC-PMC link modulated by task condition could explain individual differences in RT, according to PEB, however this connection is not significant in commonality (free-energy 0.95). As a result, I'm not sure if it's appropriate to acknowledge the contribution of the ACC-PMC connections to the RT difference. Furthermore, if the answer is yes, how should I explain why the task condition on commonalities has no effect on this connection?
Thanks in advance.
Best,
Qunjun
