Not very quickly, no. If the task needed working memory (keeping count or something), that will be gone. I'll need to take a moment to reassess what I was doing and where I'm up to. If there were X,Y,Z subtasks, I'll need to check which ones are done and which not. A long enough interruption and I might forget entirely and not return to the task at all. If someone interrupts me by trying to help, and I don't immediately understand what they're trying to do, I find that very irritating.
Disagree. I'm leaning towards Definitely Disagree but it's not a definite definitely haha.
I can't immediately switch back to what I was doing. Context switches take time and energy to focus on the task, to somehow unwind and get back in the zone.
Slightly agree. It isn’t impossible, especially if the interruption is brief and I can note where I was. But there’s also a non-zero chance that I’ll have to, at least mentally, start over.
