Darwin (1872) hypothesized that some facial muscle actions associated with emotion cannot be consciously inhibited, particularly when the to-be concealed emotion is strong. The present study investigated emotional “leakage” in deceptive facial expressions as a function of emotional intensity. Participants viewed low or high intensity disgusting, sad, frightening, and happy images, responding to each with a 5 s videotaped genuine or deceptive expression. Each 1/30 s frame of the 1,711… 

OF THE HUMAN FACE Secrets of the Human Face : New Insights Into the Face and Covert Emotions

Deception is a fundamental aspect of human communication and often is accompanied by facial expressions simulated or concealed to be consistent with the false message. Darwin hypothesized that some

Catching a Liar Through Facial Expression of Fear

There do exist facial clues to deception, and fear could be a cue for distinguishing liars from truth-tellers, and some algorithms could achieve an accuracy of greater than 80% merely using AUs of fear.

Hiding true emotions: micro-expressions in eyes retrospectively concealed by mouth movements

It is shown that brief emotional changes in the eyes (micro-expressions, thought to reflect true emotions) can be successfully concealed by follow-up mouth movements (e.g. a smile), and this results provide scientific evidence for everyday behaviours like smiling to dissemble.

Is it contagious? An eye-movement and EMG study of smile authenticity judgment

A smile is commonly used to mask negative emotions, yet those emotions are often leaked through microexpressions. These microexpressions act as brief displays of the individual’s true emotion.

The Role of Low-Spatial Frequency Components in the Processing of Deceptive Faces: A Study Using Artificial Face Models

It is suggested that hidden anger can be identified by perceiving unbalanced intensities of emotional expression between LSF and HSF information contained in deceptive faces.

Automatic Recognition of Facial Displays of Unfelt Emotions

Results show that the proposed SASE-FE dataset, the first dataset of facial expressions that are either congruent or incongruent with underlying emotion states, improves state of the art results on CK+ and OULU-CASIA datasets for video emotion recognition, and achieves competitive results when classifying facial action units on BP4D datase.

Differences between traces of negative emotions in smile judgment

While a smile can reflect felt happiness, it can also be voluntarily produced, for instance, to mask negative emotions. Masking strategies are not always perfect and traces of the negative emotion

Emotional Intelligence and Mismatching Expressive and Verbal Messages: A Contribution to Detection of Deception

A novel facial processing task that requires detection of inconsistencies between facial and verbal cues to emotion suggested that EI was correlated with superior face decoding in all conditions and confirmed the expected gender difference, the superiority of high EI individuals, and the mediation hypothesis.



Crocodile tears: facial, verbal and body language behaviours associated with genuine and fabricated remorse.

Results suggest that falsified remorse may be conceived as an emotionally turbulent display of deliberate, falsified expressions and involuntary, genuine, emotional leakage, relevant to judges and parole board members who consider genuine remorse to be an important factor in sentencing and release decisions.

Presidential speechmaking style: Emotional response to micro-expressions of facial affect

Research considering the effect of Presidential speech making style shows individuals are likely to attend to and be emotionally affected by the facial expressions of leaders, especially those that

Emotions Revealed: Recognizing Faces and Feelings to Improve Communication and Emotional Life

"A tour de force. If you read this book, you'll never look at other people in quite the same way again." Malcolm GladwellRenowned psychologist Paul Ekman explains the roots of our emotions anger,

Spontaneous facial expressions of emotion of congenitally and noncongenitally blind individuals.

Competition in the 2004 Paralympic Games provided compelling evidence that the production of spontaneous facial expressions of emotion is not dependent on observational learning but simultaneously demonstrates a learned component to the social management of expressions, even among blind individuals.

Darwin did not focus on deception, but he raised the very interesting question of whether it is difficult to voluntarily inhibit the emotional expressions that are most difficult to voluntary fabricate.

The cues decoders use in attempting to differentiate emotion-elicited and posed facial expressions

Dynamic facial expressions, either posed or elicited by afectively evocative materials, were objectively scored to determine the movement cues and temporalparameters associated with the two types of

Detecting Deception from Emotional and Unemotional Cues

Encoders were video recorded giving either truthful or deceptive descriptions of video footage designed to generate either emotional or unemotional responses. Decoders were asked to indicate the

Smiles when lying.

Subtle differences among forms of smiling distinguished when subjects were truthful and when they lied about experiencing pleasant feelings, and when smiling was treated as a unitary phenomenon.
