The TNT series stars McCormack as an offbeat neuroscientist who works as a consultant for the FBI.
TNT president and head of programming Michael Wright told Zap2It of the show: "Perception has captured the imagination of TNT's audience of armchair detectives with wonderfully intricate cases, emotionally charged situations and, of course, a terrific cast led by Eric McCormack."
The former Will & Grace actor stars alongside Arjay Smith, Kelly Rowan and Rachael Leigh Cook.
Perception, which premiered earlier this year, reportedly averages around 7 million viewers an episode in the key 25-54 demographic.
Season 2 of Perception will debut next year with a 13-episode run.
