“…Thermography's main advantage over the polygraph is that it is a contact-free technology recording the response of the autonomic nervous system. The average accuracy of lie detection with a thermal camera is 70% but may range between 70% and 90% depending on the experimental scenario of lying (Gołaszewski, Zajac, & Widacki, 2015;Pollina et al, 2006). However, regarding lie detection, in particular, but also about stress and emotions in general, we found incongruent results regarding thermal changes in the nose and forehead.…”

We applied thermography to cognitive neuropsychology, particularly as a somatic marker of subjective experience during cognitive and emotional tasks. We found significant correlations between changes in facial temperature and mental set. Specifically, the temperature of the nose tended to decrease during emotional tasks and increase during cognitive tasks. However, for stress tests or high arousal reactions to emotional stimuli, the direction of the thermal change depended on the nature of the setting, real or simulated. Detection of deception is a mixed field where cognitive effort, physiological stress, and empathy have evolved, affecting the direction of the thermal variation—higher or lower temperature of the tip of the nose and forehead. We found that the temperature change of the nose and forehead may enable detecting when people lie about facts (the Pinocchio effect markers). In general, one important contribution is to recover mental thermometry as a potent tool for neurocognitive studies.

“…In general, the thermographic detection of lies has focused on the study of thermal changes in the face (Abouelenien et al, ; Gołaszewski et al, ; Warmelink et al, ). However, different authors have focused on different parts of the face, or region of interest (ROI), as a key factor to detect the lie by its thermal change: on the periorbital area (Rajoub & Zwiggeelaar, ; Shastri, Tsiamyrtzis, & Pavlidis, ), on the forehead (Zhu, Tsiamyrtzis, & Pavlidis, ), and on the nose (Panasiti et al, ).…”

The Pinocchio effect and the Cold Stress Test: Lies and thermography

et al. 2017

We applied the use of thermography to cognitive neuropsychology, particularly as an objective marker of subjective experiences, in the context of lying. We conducted three experiments: (a) An important lie was invented by the participants in 3 min, and it was recounted by phone to a significant person while they were recorded by the thermographic camera, obtaining a face and hands map of the lie. (b) A similar methodology was carried out, but adding the Cold Stress Test (CST) of the dominant hand during the phone call, obtaining a second physiologic marker (the percentage of thermal recovery) to detect the lie. Further, it established a control condition where it generated anxiety in the participants using IAPS images with negative valence and high arousal, which were described by phone to a loved one. We obtained results that showed significant correlations between changes in body temperature and mental set. Of particular interest was the temperature of the nose and hand, which tended to decrease during lying (Experiment 1). The participants also showed a lower recovery of the temperature after the CST when they were lying (Experiment 2). (c) Experiment 3 is a replication of Experiment 2 but with a different type of lie (a more ecological task) in a different scenario (following the ACID interview, with the use of the phone eliminated and participants motivated to lie well). The main pattern of results was replicated. We obtained an accuracy of 85% in detection of deception with 25% of false alarms.

The article introduces the results of a study exploring the connection of individual characteristics with the ability to recognize hidden information. The study involves 80 psychology students. The subjects of the experiment tried to separate the lies from the truth in specially recorded videos imitating recruitment interviews. The results show that subjects who successfully recognize falsehood, compared to others, demonstrate a low level of neuroticism (F equals 5.488, p is less than 0.05) and high level of intrapersonal emotional quotient (F equals 3.581, p is less than 0.05). The data obtained suggest that the ability to recognize hidden information is associated with a low level of anxiety and high level of selfawareness.
