Subclaims¶

q3 i? Participants who played Crystals showed increased DMPFC–posterior cingulate rs-fMRI connectivity following gameplay relative to Bastion participants, within a mask of empathic accuracy-related regions. → Kral 2018 q3 i? Change in DMPFC connectivity within the empathic accuracy-related network mask was not related to change in empathic accuracy for Crystals participants. → Kral 2018 (2)

Kral 2018¶

Kral, T. R. A., Stodola, D. E., Birn, R. M., Mumford, J. A., Solis, E., Flook, L., Patsenko, E. G., Anderson, C. G., Steinkuehler, C. & Davidson, R. J. (2018).

q3 · i? · causal · r2

Voxel-wise analysis within an independently defined empathic accuracy-related network mask (family-wise corrected p < 0.05) found the group difference in DMPFC–PCC connectivity change; connectivity also increased within the Crystals group, and no regions favored Bastion.

"Participants who played Crystals had increased DMPFC –posterior cingulate rs-fMRI connectivity following game-play, relative to participants who played Bastion"

Kral, T. R. A., Stodola, D. E., Birn, R. M., Mumford, J. A., Solis, E., Flook, L., Patsenko, E. G., Anderson, C. G., Steinkuehler, C. & Davidson, R. J. (2018).

q3 · i? · causal · r2

Follow-up test within Crystals found the DMPFC network connectivity change was not significantly related to empathic accuracy change (t(28) = 1.22, p = 0.23); no significant group differences emerged for VMPFC or RTPJ seeds or in whole-brain analysis.

"Changes in DMPFC connectivity within the empathic accuracy-related network mask were not related to changes in empathic accuracy for Crystals participants ( t(28) = 1.22, p = 0.23"
