Journal of Language and Social Psychology special issue editors Drs. Steven McCornack and Timothy Levine discuss research featured in their issue, "Advances in Deception Theory." The issue focuses on two new theories of deception: Information Manipulation Theory 2 (IMT2; McCornack, Morrison, Paik, Wisner, & Zhu, 2014) and Truth Default Theory (TDT; Levine, 2014). These focal works are followed by peer reviewed, expert commentaries by Cole (2014), Greene (2014), Harwood (2014), Walczyk (2014), Van Swol (2014), and Verschuere and Shalvi (2014), and a look at the future of deception theory.
