Both self- and other-regarding motivational signals can be added together using gain modulations in a weighted manner (WS and WO , respectively) to result in a representation in a common (both-centered) frame of reference. The relative distribution of WS and WO determines the strength of self- and other-regarding signals for the both-centered representation. The self-centered signals directly influence self-regarding preferences (either positive or negative in valence, +/-), whereas the other-centered signals directly influence other-regarding preferences (either positive or negative in valence). On the other hand, the commonly-referenced, both-centered, signals may influence the self- and other-regarding preferences, and the strength of each influence depends on WS and WO . The self- and other-regarding preference signals are relayed to the output layer to generate different social decisions and actions.representation for the signals with respect to self in the bothcentered representation, whereas the opposite pattern is http://svetisavaflemington.org/members/mosque80honey/activity/329021/ apparent when there is a greater influence of other-regarding motivational signals (WS WO ) will result in a strongerFIGURE 3 | A proposed schematic model of how social variables represented in self- and other-centered, as well as common (both-centered), frames of reference may mediate social interactions. In the cognitive layer, neuronal signals resulting from the environment (input layer) are represented in an agent-nonspecific frame of reference. Motivational (and other cognitive) signals regarding oneself (self motivation variables; see examples in the text) can be added using gain modulations (G) to generate a representation in a self-centered frame of reference, whereas motivational (and other cognitive) signals regarding others (other-regarding and vicarious motivation variables; see examples in the text) can be added using gain modulations to generate a representation in an other-centered frame of reference. Neuromodulators (see examples in the text) sets the gain parameters (e.g., magnitude, context) of self- and other-regarding motivational signals in a context-dependent manner. Both self- and other-regarding motivational signals can be added together using gain modulations in a weighted manner (WS and WO , respectively) to result in a representation in a common (both-centered) frame of reference.
