The stare-in-the-crowd effect is the notion that an eyes-forward, direct gaze is more easily detected than an averted gaze. First discovered by psychologist and neurophysiologist Michael von Grünau and his psychology student Christina Marie Anston using human subjects in 1995, [1] the processing advantage associated with this effect is thought to derive from the importance of eye contact as a ...
The thousand-yard stare (also referred to as two-thousand-yard stare) is the blank, unfocused gaze of people experiencing dissociation due to acute stress or traumatic events. It was originally used about war combatants and the post-traumatic stress they exhibited but is now also used to refer to an unfocused gaze observed in people under a ...
The concept of the "male gaze" was first used by the English art critic John Berger in Ways of Seeing, a series of films for the BBC aired in January 1972, and later a book, as part of his analysis of the treatment of the nude in European painting. Berger described the difference between how men and women view and are viewed in art and in society.
The conjugate gaze is the motion of both eyes in the same direction at the same time, and conjugate gaze palsy refers to an impairment of this function. The conjugate gaze is controlled by four different mechanisms: [4] the saccadic system that allows for voluntary direction of the gaze; the pursuit system that allows the subject to follow a ...
Oculesics is one form of nonverbal communication, which is the transmission and reception of meaning between communicators without the use of words.Nonverbal communication can include the environment around the communicators, the physical attributes or characteristics of the communicators, and the communicators' behavior of the communicators.
For example, a 9-month-old infant will shift its gaze towards an object in response to another face shifting its gaze towards the same object. [16] As humans get older, the eye contact effect develops as well. Accurate face recognition facilitated by direct gaze improves over the period of development from 6 to 11 years of age. [17]
Due to potential drifts and variable relations between the EOG signal amplitudes and the saccade sizes, it is challenging to use EOG for measuring slow eye movement and detecting gaze direction. EOG is, however, a very robust technique for measuring saccadic eye movement associated with gaze shifts and detecting blinks. Contrary to video-based ...
The JND formula has an objective interpretation (implied at the start of this entry) as the disparity between levels of the presented stimulus that is detected on 50% of occasions by a particular observed response, [3] rather than what is subjectively "noticed" or as a difference in magnitudes of consciously experienced 'sensations'.
