The Effect of the Physical Presence of Co-Players on Perceived Ostracism and Event-Related Brain Potentials in the Cyberball Paradigm
Figure 1
Experimental setting for the Internet (I) and Presence (II) condition.
The real participant was always sitting at position C. In the Internet group, the two “co-players” were depicted by two photographs. In the Presence group, the confederates “A” and “B” pretended to be involved in the ball tossing game, which was actually possible only in 15 training trials at the beginning of the game. Please note that the photographs of co-players depicted do not refer to real persons, but are morphs of different portraits.
