Table 2. Simulations of Overshadowing With Delay Procedures (No Trace) or With Trace Procedures (Short and Long Trace).

Procedure No Trace Short Trace Long Trace
Note. Trace procedures result in less associative strength (V), but in compound training procedures more generalization (similarity) from compound BX to the elements X. Values in bold represent the predicted response.
Elemental VX = 0.7 VX = 0.5 VX = 0.3
XSX = 1 XSX = 1 XSX = 1
EX = 0.7 × 1 = 0.7 EX = 0.5 × 1 = 0.5 EX = 0.3 × 1 = 0.3
Compound VBX = 0.7 VBX = 0.5 VBX = 0.3
XSBX = 0.3 / 0.7 × 0.3 / 0.7 = 0.18 XSBX = 0.5 / 0.5 × 0.5 / 0.5 = 1 XSBX = 0.7 / 0.3 × 0.7 / 0.3 = 5.4
EX = 0.7 × 0.18 = 0.12 EX = 0.5 × 1 = 0.5 EX = 0.3 × 5.4 = 1.6
