“…The anterior cingulate activation that was found by Langleben et al (2002) and Kozel et al (2005) was consistent with our findings. The MPFC activations that were found by Ganis et al (2003), Phan et al (2005), and Abe et al (2008) were also consistent with many self-relevance studies, as described in the introduction. However, the activation in the right superior frontal gyrus that was reported by Abe et al (2008) is not consistent with the findings of self-relevance studies and with our findings.…”

“…Unlike lie detection, whether the subject tells the truth or a lie is not our concern. In many fMRI studies (Abe et al, 2008;Ganis, Kosslyn, Stose, Thompson, & Yurgelun-Todd, 2003;Kozel et al, 2005;Langleben et al, 2002;Phan et al, 2005), brain activity comparisons between deceptive and truthful responses have been found to be different. The anterior cingulate activation that was found by Langleben et al (2002) and Kozel et al (2005) was consistent with our findings.…”

The true intentions of humans are sometimes difficult to ascertain exclusively from explicit expressions, such as speech, gestures, or facial expressions. In this experiment, functional magnetic resonance imaging (fMRI) was used to investigate implicit intentions that were generated while a subject was reading self-relevant sentences. Short sentences, which were presented visually, consisted of self-relevant statements and a substantive verb, which indicated sentence polarity as either affirmative or negative. Each sentence was divided into the contents and the sentence ending, and the subjects were asked to respond with either agreement or disagreement after the complete sentence was presented. The overall group analysis suggested that the intention of the sentence response was found even before the reading of the complete sentences. Increased neural activation was found in the left medial prefrontal cortex (MPFC) during feelings of agreement compared to feelings of disagreement during self-relevant decision-making. In addition, according to the sentence ending, the decision of a response activated the frontopolar cortex (FPC) in the switching condition. These findings indicated that the implicit intentions of responses to the given statements were internally generated before an explicit response occurred, and, hence, intentions can be used to predict a subject's future answer.

“…One possibility is that the intention to conceal elicits a deception-specific process during the CIT, and ERPs reflect it. The existence of such a deception-specific process has been demonstrated in ERP studies (e.g., Johnson et al 2003Johnson et al , 2004Johnson et al , 2005 and in brain imaging studies (e.g., Abe et al 2006;Ganis et al 2003;Langleben et al 2002;Phan et al 2005). The other possibility is that a general process not specific to deception, such as need for additional processing or increased significance/salience of an item, is responsible for the P300 increase.…”

The present study examined whether intention to conceal knowledge affects P300 amplitude and detection accuracy in the concealed information test. Eighteen university students were told to choose one card from five and to hide it. In the conceal condition, participants made an effort to leave their chosen card undetected by suppressing their brain response to it. In the transmit condition, they attempted to inform the experimenter of the chosen card by enhancing brain response to it. In the no secret condition, participants showed the chosen card to the experimenter beforehand and lost their motivation to conceal it. The difference in P300 amplitude between the chosen and unchosen cards was significant only in the conceal and transmit conditions. The results suggest that a larger P300 amplitude for the chosen card was not due to a deception-specific process but rather to increased significance of the item caused by additional processing.

“…Although the CIT is not a test of deception, it was reasoned that the denial of relevant-item knowledge causes a conflict between the truthful and the required deceptive response, which is resolved by inhibiting the former response (Seymour & Schumacher, 2009;Verschuere & De Houwer, 2011). Response inhibition has been indicated to play a role in the CIT based on Reaction Time (Suchotzki, Verschuere, Peth, Crombez, & Gamer, 2014) and fMRI measures (e.g., Gamer, 2014;Gamer, Bauermann, Stoeter, & Vossel, 2007;Langleben et al, 2002;Phan et al, 2005), but it remains unclear whether it plays a role in the autonomic-based CIT (see Ambach, Stark, Peper, & Vaitl, 2008a;Ambach et al, 2011). Indeed, meta-analytic studies have demonstrated that similar CIT effects were observed with the SCR measure when subjects responded deceptively to the relevant items and when they remained silent and did not give any overt responses (Ben-Shakhar & Elaad, 2003;Meijer, klein Selle, Elber, & Ben-Shakhar, 2014).…”

Orienting versus inhibition in the Concealed Information Test: Different cognitive processes drive different physiological measures

et al. 2015

View full text Add to dashboard Cite

The Concealed Information Test (CIT) provides a valid tool for psychophysiological detection of concealed knowledge. However, its precise theoretical underpinnings remain a matter of debate. The differential physiological responses elicited by concealed, relevant items, relative to control items, were traditionally explained as reflecting an Orienting Response (OR). According to an alternative account, these responses reflect attempts to inhibit arousal. The present study examined whether and to what extent CIT detection efficiency is affected by instructions aimed at manipulating Arousal Inhibition (AI). One-hundred and forty-seven undergraduate students completed a CIT, while electrodermal, cardiac and respiratory measures were recorded. Half of the participants were requested to imagine that they are suspected of committing a crime and were motivated to avoid detection (presumably eliciting both OR and AI), while the other half were requested to imagine that they are witnesses of a crime and were motivated to be detected (presumably eliciting OR only). All participants were further requested to remain silent throughout the test. In both conditions, concealed items led to a similar increase in skin conductance as compared to the control items. However, the typically observed heart rate deceleration and respiratory suppression were found in suspects, but not in witnesses. These data imply that different mechanisms drive the responding of different psychophysiological measures used in the CIT, with skin conductance reflecting OR, and heart rate and respiration primarily reflecting AI.
