Nauman pioneered the use of neon text as sculpture to deliver emotionally and psychologically charged language, creating immersive environments where phrases like 'Human Nature' and 'Run from Fear' confront viewers directly. His combination of sculptural form with glowing text based affirmations and provocations mirrors Hopgood's fusion of neon language and physical objects to explore vulnerability and mental states.

Etchells creates large scale neon text installations featuring emotionally direct phrases such as 'Everything is Possible' and 'You Can Hear Me' that invite collective reflection on identity, hope, and human connection. His British origin and consistent use of glowing affirmational language as immersive sculptural environments align closely with Hopgood's approach in Chair Therapy Group.

Montgomery is known for large scale text based installations and neon works featuring poetic, emotionally resonant phrases about love, loss, and hope that create an atmosphere of collective vulnerability and uplift. His British identity, use of neon and typography as the primary artistic medium, and focus on mental and emotional states parallel the specific qualities of Hopgood's Chair Therapy Group.
