layers of functionalities within the reactor and deliberator, each architecture
in the Hybrid Paradigm has obvious partitions between reactive and delib-
erative functions.

7.2.1 Characteristics and connotation of reactive behaviors in hybrids

The Hybrid Paradigm is an extension of the Reactive Paradigm, and from
the above description, it would appear that the behavioral component is un-
touched. That is not entirely true. Behaviors in the Hybrid Paradigm have a
slightly different connotation than in the Reactive Paradigm. In the Reactive
Paradigm, “behavior” connotes purely reflexive behaviors. In the Hybrid
Paradigm, the term “behavior” is usually more consistent with the etholog-
ical use and includes reflexive, innate, and learned behaviors. This can be
SKILL VS. BEHAVIOR confusing, and at least one architecture uses the term skill instead of “be-
havior” to avoid confusion with purely reflexive behaviors. Also, Hybrid
implementations tend to use assemblages of behaviors sequenced over time,
