I examined the impact of targets’ language proficiency on observers’ lie detection accuracy, discrimination, bias, and confidence. Observers (N = 132) were randomly assigned to make deception judgments about targets (N = ...

It is currently unknown how lie detection accuracy is affected when someone is speaking in his or her second language. We examined whether language proficiency had an impact on lie detection. We hypothesized that when ...

I examined whether observers’ own language proficiencies would affect their lie detection judgments. In a previous study, native- and second-language English speakers were videotaped as they either lied or told the truth ...

Little is known about the underlying components that are responsible for the processes involved with decision-making in deception detection. Throughout this dissertation, I explored previous (mis)conceptions about ...

I examined whether the length of thin slices (i.e., observations of behavior less than five minutes) affected deception detection. Participants (N = 262) were randomly assigned to one of seven exposure length conditions ...

Using a dual-task paradigm, I examined how engaging in executive function tasks impacted deception detection and memory performance. University students (N = 185) were randomly assigned to detect deception while also ...
