Detailed explanation-1: -A fixed action pattern is a predictable series of actions triggered by a cue, sometimes called the key stimulus. Though a fixed action pattern is more complex than a reflex, it’s still automatic and involuntary. Once triggered, it will go on to completion, even if the key stimulus is removed in the meantime.

Detailed explanation-2: -A Fixed Action Pattern, often abbreviated as FAP and known alternatively as Instinctive Movement or Instinct Bewegung, is a predictable series and stereotypical sequences of complex actions triggered by a cue.

Detailed explanation-3: -Fixed Action Pattern (FAP) is a sequence of coordinated movements that are performed together as a “unit” without interruption. Each FAP is triggered by a unique stimulus variously known as a sign stimulus, a key stimulus, or a releaser. A praying mantis striking at prey is a typical example.

Detailed explanation-4: -While scientists are hard-pressed to discover any perfect examples of fixed-action-patterns in humans, all Homo sapiens are born with basic instinctual behaviors. For example, a newborn infant will reflexively grab on to any object that is tendered.

Detailed explanation-5: -Independent of experience: A fixed action pattern is not learned. This is known as a fixed action pattern is complete upon the very first release.
