Lie-detecting software uses real court case data. By studying videos from high-stakes court cases, University of Michigan researchers are building unique lie-detecting software based on real-world data.

Researchers at the University of British Columbia enlisted the help of a human-friendly robot named Charlie to study the simple task of handing an object to a person. Past research has shown that people have difficulty figuring out when to reach out and take an object from a robot because robots fail to provide appropriate nonverbal cues. "We hand things to other people multiple times a day and we do it seamlessly," says AJung Moon, a PhD student in the Department of Mechanical Engineering. "Getting this to work between a robot and a person is really important if we want robots to be helpful in fetching us things in our homes or at work.

Facial Action Coding System. Muscles of head and neck.
Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. It was later adopted by Paul Ekman and Wallace V. Friesen, and published in 1978. Ekman, Friesen, and Joseph C. Hager published a significant update to FACS in 2002. Movements of individual facial muscles are encoded by FACS from slight different instant changes in facial appearance. It is a common standard to systematically categorize the physical expression of emotions, and it has proven useful to psychologists and to animators. Due to subjectivity and time consumption issues, FACS has been established as a computed automated system that detects faces in videos, extracts the geometrical features of the faces, and then produces temporal profiles of each facial movement. Uses
Body Language ⭐ Polygraph. Prosody (linguistics) There is no agreed number of prosodic variables.
In auditory terms, the major variables are the pitch of the voice (varying between low and high)length of sounds (varying between short and long)loudness, or prominence (varying between soft and loud)timbre (quality of sound) in acoustic terms, these correspond reasonably closely to fundamental frequency (measured in hertz, or cycles per second)duration (measured in time units such as milliseconds or seconds)intensity, or sound pressure level (measured in decibels)spectral characteristics (distribution of energy at different parts of the audible frequency range) Some writers have described intonation entirely in terms of pitch, while others propose that what we call intonation is in fact an amalgam of several prosodic variables.
Paralanguage. Paralinguistic information, because it is phenomenal, belongs to the external speech signal (Ferdinand de Saussure's parole) but not to the arbitrary conventional code of language (Saussure's langue). The paralinguistic properties of speech play an important role in human communication. There are no utterances or speech signals that lack paralinguistic properties, since speech requires the presence of a voice that can be modulated. This voice must have some properties, and all the properties of a voice as such are paralinguistic. However, the distinction linguistic vs. paralinguistic applies not only to speech but to writing and sign language as well, and it is not bound to any sensory modality. Even vocal language has some paralinguistic as well as linguistic properties that can be seen (lip reading, McGurk effect), and even felt, e.g. by the Tadoma method.

In the new study 'Building trust: Heart rate synchrony and arousal during joint action increased by public goods game' (Journal of Physiology and Behavior) PhD and assistant professor Panagiotis Mitkidis and colleagues from the Interacting Minds Centre at Aarhus University studied the link between heart rate and trust.
They had 37 pairs of participants do a cooperative task involving building LEGO cars. The control group only did the LEGO task, while a second group played an investment game in between the building sessions. The game, known as the 'Public Goods Game', had the goal of including the element of trust in the experiment. "When people are in the progress of building trust among each other their hearts get in synchrony and beat as one. Trust is a necessary ingredient for successful cooperation and of most importance for our society," states Panagiotis Mitkidis, PhD, assistant professor, Aarhus University. What are microexpressions? After taking just one look at someone, why do we sometimes immediately know we don't like him or her? We usually chalk this up to instinct, intuition or a "gut feeling," but researchers have found that there's something more going on that just barely meets the eye -- microexpressions. The human face is a medium, or a sign vehicle, that sends us a message.
The science of sexiness: why some people are just more attractive. Probably the most important is facial symmetry. Having a face which is equal on both sides is a biological advert which tells prospective partners that good genes will be found in this body.
