Throw away jargon as much as possible and elucidate the fundamental difference between both terms. Thanks.
I see that nobody has responded. So I’ll try. But, in truth, it’s a hard question. I have managed to make it through my entire life without being sure what is a concept. I guess I can make it for the few remaining years.
For “construct”, what that means can depend on context.
Sorry to not be more helpful.
The way I see it, constructs are highly abstract concepts. Terms like “self-esteem” are highly abstract concepts (constructs) as they have no tangible referents.
