Joint Attention
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A foundational capacity in developmental psychology, studied by Michael Tomasello and others, in which two agents focus on the same object while mutually registering that focus. The core proposition is that the mutual awareness, not the shared object alone, is what makes joint attention distinct, and it underpins language learning, intention reading, and cooperation. The key qualification is that it requires that second-order awareness.
SCAFFOLDING EFFECT
Reduce cognitive load
- Mutual registration: confirm explicitly that both parties are looking at the same thing. - Pointing move: use a gesture or reference to establish a shared target. - Topic anchor: build the conversation on the object you both now attend to.
Anchor fast decisions
Once two agents register each other's focus, each can use the other's reactions as information about the object, which is how social referencing works. The mutual awareness also creates a shared referent that language can attach to, which is why vocabulary is learned far faster in joint attention episodes. Without the second-order awareness, the same physical scene supports no coordination.
