Abstract
This study examined the ability of students to correctly discern between truthful and deceptive messages from a group of second language English speakers. Recent studies have found a ‘lie bias’ when making veracity judgments towards second language speakers. This lie bias may be problematic in a country such as South Africa where the majority of the population communicate, to a greater or lesser extent, in their second language. In this study participants (n=64) made classifications of 24 messages as either truthful or deceptive. The messages were created by second language English speakers who were asked to describe a truthful or deceptive event. The results revealed that there was a significant difference between the way that first and second language participants made their judgments. It is argued that this difference can be attributed to the notion that second language participants require more cognitive effort, than their first language counterparts, to understand and classify messages.
