Note. Entries are parameter estimates and standard errors (in parentheses).

*

parameter estimate with p < .05.

n

parameter estimate with p > .05.

Intercept = scores at baseline.

a

changes per measurement occasion.

b

total changes from baseline to four months post pairing.

c

percentage of changes from the baseline to 7-days post pairing.

d

Explained variance due to time and group effects.

Number of subjects = 13; number of observations = 43. Group code (−1 = control; +1 = experimental). Factor 1 includes Motivational areas (NAcc, VP, Caud, Put); Factor 2 includes social areas (MeA, LS, MPOA, PCC); Factor 3 includes control areas (PAG, Cere); Factor 4 includes OT and AVP producing nuclei (PVN, SON); Factor 5 is the prefrontal cortex (PFC).
