Abstract
This study proposed that criminal guilt interacts with dominance and interview question to affect linguistic properties during criminal interviews. A field experiment tested effects of criminal guilt, dominance, and question on linguistic properties of suspects’ responses using a 2 (criminal guilt: guilty/innocent) × 4 (question: Q1/Q2/Q3/Q4) mixed-model design with dominance as a covariate and question as a repeated factor. Analysis of linguistic properties from 37 criminal interviews indicated a hypothesized two-way interaction among dominance and guilt on immediacy and a three-way interaction among dominance, question, and guilt on complexity explored as part of the research question. Several other direct effects for dominance and question were noted. Implications, limitations, and future research directions are discussed.
