Simulation results suggest that corrupting connection weights between room and arena cells is necessary and sufficient to induce selective subgrouping failures

Corruption rule Maximal tolerated corruption Critical p for representation failures Critical p for subgrouping failures
General: Eq. 5a
Selective: Eq. 5b Corrupted weights
General Room—arena p = 0.21 p ≥ 0.21 p ≥ 0.13
Selective Room—arena p = 0.24 p ≥ 0.24 p ≥ 0.15
General Room—room and arena—arena p = 0.22 No failures for p ≤ 0.22 No failures for p ≤ 0.22
Selective Room—room and arena—arena p = 0.32 No failures for p ≤ 0.32 No failures for p ≤ 0.32
