This repository provides data and code needed to reproduce all analyses reported in Scholz, Baek, O'Donnell, Falk (2019). Decision-making about broad- and narrowcasting: A neuroscientific perspective. Media Psychology. DOI: 10.1080/15213269.2019.1572522.
NOTE: We report that neural activity in the contrasts of interest is not significantly associated with the size of participants' ego Facebook network. We are currently not including network size in the datasets provided here while we review our policy on participant privacy protection and data sharing.
Data files:
-
Percent signal change in ROIs during reading screen periods of the Article task in three contrasts: Narrowcasting > Control (NARROWvsCONTENT_read), Broadcasting > Control (BROAD>CONTENT_read), Narrowcasting > Broadcasting (NARROWvsBROAD_read):
