A Mechanism for Value-Sensitive Decision-Making

Figure 5

Full bifurcation behaviour of the stop-signal model of Eq. 1.

According to parameterisation of the decision problem and decision-maker, the dynamics include (i) pitchfork bifurcation as a function of cross-inhibition rate in the equal alternatives case, (ii) saddle-node bifurcation as a function of cross-inhibition in the unequal alternatives case, and (iii) hysteresis as a function of difference in value of alternatives . Fixed points are projected onto the line as described in Text S1 and Figure S4. Blue dots indicate stable attractors, and red indicate unstable saddle points. Decision thresholds at are indicated by dashed lines.
