McClelland [McClelland, McNaughton, and O'Reilly (1995)] describes trying to teach a computer simulation of this neocortical memory system about the properties of birds. The network performs well when it is given lots of examples of birds, and is told that all of them can fly. However, when it is presented with a penguin, a bird that cannot fly, the network experiences catastrophic interference and responds either by classifying the penguin as a nonbird or by concluding that birds cannot fly after all.
This description of "catastrophic interference" is clearly reminiscent of clinical accounts of how trauma overturns long-held assumptions and is hard to integrate with previous knowledge. In the process known as "overassimilation" (Resick & Schnicke, 1993) some traumatized people attempt to deny the reality of the event and turn it into a nontrauma, equivalent to trying to turn the penguin into a nonbird. In the process Resick and Schnicke term "overaccomodation", people let the fact of the trauma overturn everything they previously assumed to be true, equivalent to concluding that birds cannot fly.
