I could argue that, given the multiple timescales of the human condition
(lemke), and how culture plays a role in psychology, crossing timescales,
(e.g. the description of prolepsis in 'cultural psychology"), and the
description by Leont'ev of the "hierarchical structure of activity", plus the
historical analysis included in Engestrom's expansive methodology, that one
would abductively think multiple units of analysis, crossing at least many
timescales, if not also some scales along other dimensions, could be
desireable and even practicable. This methodological potential seems
embedded in the CHA of CHAT.
Practically, multiply scaled units of analysis are useful only if such
methods coincide with the goals of the intended study.
I'm sorry I cannot add more -- it's just a passing thought, a humble opinion.
And I have no formal training, so take it for what it's worth.
