Figure 1 - Humphrey field analyser. Humphrey field analyser (HFA) is a tool for measuring the human visual field that is commonly used by optometrists, orthoptists and ophthalmologists, particularly for detecting monocular visual field. [1] The results of the analyser identify the type of vision defect.
Visual field testing can be performed clinically by keeping the subject's gaze fixed while presenting objects at various places within their visual field. Simple manual equipment can be used such as in the tangent screen test or the Amsler grid. When dedicated machinery is used it is called a perimeter.

The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; [1] in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.
Microperimetry, sometimes called fundus-controlled perimetry, [1] is a type of visual field test [2] which uses one of several technologies to create a "retinal sensitivity map" of the quantity of light perceived in specific parts of the retina [3] in people who have lost the ability to fixate on an object or light source.
The Language Preservation Project conducted a study on Latinos in the Denver area who lost their heritage language, and Benavides said it found two major themes: People felt pride when they could ...

In 1984 Humphrey left his academic post at Cambridge to work on his Channel 4 television series The Inner Eye, on the development of the human mind. This series was finished in 1986 with the release of a book of the same name. In 1987, Daniel Dennett invited Humphrey to work with him at his Center for Cognitive Studies at Tufts University.
