They acknowledge that tasks that attempt to test a certain executive function such as memory have some variability amongst them, for this reason they used factor analysis

I know the sentence contains some jargon, so I will try to explain the logic as best as I can. The variability among the tasks is why they use factor analysis, however it most certainly is not the only thing they could have done. Is there a difference between therefore and for this reason in such a situation. My intuition tells me that therefore implies more certainty that this is the only possible effect.


Both can be used in most contexts. For this reason has an effect of sounding like a person chose to do something. Therefore has a more analytical effect, as in an opinion in an essay.

However, they are interchangeable.

  • Thank you, yes this sounds about right.
