Does the viewer realise that his view is being regularly blocked? Does he activate the removal option before time runs out?
I understand what you are doing but the Gorilla experiment is specifically designed to overload the visual / spatial cognitive channel. The theory is that each of us only has cognitive channels that deal with various information inputs. These channels can get overloaded. This is why designers use haptics (feel/touch) like a stick shaker to break through otherwise full cognitive channels. A good example of a cognitive channel is the visual verbal - try to recite a nursery rhyme while you read a paragraph and understand what someone is saying to you. You cannot do all three as your verbal cognitive channel is overloaded. It does appear from what people are saying here that there are some failures that are a cognitive nightmare with visual verbal, aural verbal, graphical, alerts other pilot talking/shouting and the actual handling of the aircraft. This is a common failing the same was said about the AF447 likely explosion of warnings and alerts.
Perhaps the memory items shouldn't be a reasoned chain but a list of immediate safe quick fixes. So for example with Unreliable Airspeed, first action disable stab trim - then go through the subsequent checks replacing stab trim as a last step if the checks indicate that it is safe.
