Exposure therapy is a situation when conditioned fear is recent vs. remote. These graphs show what fear and B_Rep would be like during a mock virtual reality extinction session in which the proportion of overlap of the context’s particulars with those of the conditioning context was 0.6 and the category known, as in the simulations of Figure 9. Fear inhibition would become conditioned to the conditioned context’s representation while that representation was active and would persist beyond the session to the extent that the B_Rep of the (red-graphed) representation was greater than at the end of the session. When the conditioned representation was recent, any inhibition that became conditioned to the feared representation would not outlast the session even if the session were terminated before a representation of the therapy session itself was created because B_Rep of the conditioned context never got above B_xBtwn; however, when the representation was remote, termination of the session a bit before Z_cur = 80 would result in some long-lasting inhibition that would be effective in suppressing fear in real-world contexts similar to the conditioning contexts because B_Rep of the conditioned context did exceed B_xBtwn in the latter part of the session.
