Definition

Top-down constraint is the shaping of component possibilities by the organization of a larger system, while that organization remains dependent on lower-level enabling conditions. The corpus uses it for maintained architectures, contextual scaffolds and integrated biological form. It is not an external whole imposing a new fundamental force, nor does its general role make every claim about top-down perceptual influence an independently established result.

Explanation

RB1 describes the whole as a dynamically enacted regime narrowing degrees of freedom. Its later Peacocke comparison explicitly says downward influence is organizational constraint rather than a new kind of cause. This preserves efficacy at the whole-system level without imagining an independent controller separate from its constituents.

RB3’s Riedl account adds reciprocal dependence among levels. A changed component must remain viable within an integrated structure, while higher-level regularities rely on lower-level integrity. Top-down and bottom-up therefore name interacting explanatory directions, not a ranking that grants one scale all causal priority.

RB2 applies the term to earlier coordination retained in bodily and social scaffolds, and separately reports Clark’s top-down predictive flow. Its native apparatus also records criticism of purported perceptual effects. These are different local uses and evidential questions; the organizational principle alone cannot certify every experiment or collapse ecological perception and predictive processing into one theory.
