La successiva ed ultima metastruttura discussa da Tyler Volk e Jeff Bloom sono i triggers, intesi come centri o elementi di azione per l'inizio e la generazione di processi più estesi e complessi:
Background
Triggers are related to centers in that they are a central factor in a particular system. However, triggers involve the notion of stimulating or initiating a particular action or series of actions.
Examples
- In science: reflex, freezing of certain plant seeds trigger their growth, catalysts, plate tectonic movement triggers volcanic activity and earthquakes, earthquakes can trigger tsunamis, heart beats are triggered by one and several back-up mechanisms, etc.
- In architecture and design: gas pedals in cars, brakes in cars, elevator buttons, metal scanners in airports, etc.
- In the arts: images that trigger emotions, an idea that triggers a creative representation, compressed conflict in literature, etc.
- In social sciences: cognitive dissonance can trigger new ideas and questions, memories are triggered by smells and other stimuli, ideas or events that stimulate new connections, etc.
- In other senses: gun triggers, “pushing someone’s buttons,” love at first sight, in sports the wind-up (torque) of a golf swing or baseball batter is triggered into a release, clues trigger-point massage, Zen koan, racial profiling, cues, etc.
