SIP Interviews

Deceptive statements will contain more negative emotion words, motion verbs and exclusion words compared to truthful statements. In addition to the model, we expect deceptive statements to include fewer words and more positive emotions words than truthful accounts. Secondly, in line with the Reality Monitoring framework, we predict that participants will provide more perceptual, spatial and temporal information in their truthful statements compared to their deceptive ones. In terms of cognitive operations, we expect truthful statements to include more linguistic cues referring to cognitive processes and insight words. Finally, we expect that authenticity and analytic variables, new to LIWC 2015 version, will be higher in participants’ truthful accounts. Based on extensive research on arousal as an indicator of deception, we expect physiological and behavioural differences between truthful and deceptive statements. We predict that …show more content…
Specifically, we examined the amount and the characteristics of information that was obtained. Interviewees engaged in SIP interview will produce longer responses, report more perceptual, spatial and temporal details, positive emotion words, will experience less cognitive demand and use less negative emotion words, than interviewees engaged in the baseline interview. Analytic and authentic thinking is anticipated to be greater in the SIP interview than the baseline. We also posit significant differences between the SIP and Baseline interview on the physiological (HR and EDA) and behavioural (ACC) signals as an indicator of the rapport building component effectiveness. Finally, based on the ‘interviewing to detect deception’ approach, we expect that the SIP interview will make linguistic and physiological differences between truthful and deceptive statements easier to
