Richard Wilson's 1988 installation 20 50, a room-filling tank of sump oil, so perfectly reflective that it confuses the eye, is a test of perception, and in its latest manifestation in the Saatchi Gallery continues to catch the unwary with substantial empirical proof of what it really is.
A test of perception with sixteen lines, each with eight simple pictures of which only two were exactly identical.
Cognitive impairment in tests of perception [3, 7 11], visual attention [12], information speed processing [11 13], simple reaction time (RT) [14] and verbal ability [15 17] have been documented in migraine subjects.
All were deficient on face matching tests and severely impaired on tests of perception of the spatial relations of facial features and abstract designs, indicating a deficit in the encoding of coordinate relationships, similar to adult-onset prosopagnosia with lesions of the fusiform face area.
This omission is in one sense appropriate, because a goal of MATRICS was to identify existing neuropsychological tests that are useful for clinical trials of schizophrenia, and tests of perception are not widely used by neuropsychologists.
The Mooney Face Test is a widely used test of face perception, but was originally designed to be administered by personal interview.
The Words in Noise Test (WIN) [65] is a non-adaptive test of speech perception in four-talker babble noise (three females and one male), presented binaurally to participants through Etymotic ER-2 insert earphones [65].
Visual perception Motor-free visual perception test (MVPT-3) : assesses an individual's visual perceptual ability with no motor involvement needed to make a response Developmental test of visual perception adolescent and adult (DTVP-A) : a comprehensive measure of visual perception that reliably differentiates visual-perceptual problems from visual-motor integration deficits.
We chose a test of emotional perception, which assesses the ability to identify the emotions expressed in videos of people.
The current study was designed to provide a rigorous test of affect perception abilities among schizophrenia patients (n=58), their biological siblings without psychosis (n=51), and nonpsychiatric controls (n=49).
This provides a new and interesting test of Bayesian perception, because if the nervous system was to necessarily fuse the modalities first and use the fused estimates to detect oddity, then it would not be able to detect such metamers.
