Mental Rotation by Neural Network
2009 Fifth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2009This paper proposes a new and compact method for object image retrieval fusing Dominant Colors (DCs) and embedded Markov chain concepts. This proposed method uses combined color-texture features which are characterized in terms of their spatial interaction or interrelationship properties, modeled by means of a set of embedded Markov chains, each ...

Mental rotation in a commissurotomized subject
Neuropsychologia, 1989The commissurotomized subject L.B. showed a strong right-hemispheric advantage on a task requiring him to judge rotated letters normal or backward, but a left-hemispheric advantage in a task requiring discrimination of the same letters, implying that the right-hemispheric advantage has to do with mental rotation.

Mental rotation: an examination of assumptions
WIREs Cognitive Science, 2017Since first presented by Shepard and Metzler, Science 1971, 171: 701–703, mental rotation has been described as a rotary transformation of a visual stimulus allowing it to be represented in a new orientation. For a given stimulus, the transformation is thought to occur at a constant speed, though speed may vary between stimuli; three‐dimensional ...

Developmental changes in mental rotation
Journal of Experimental Child Psychology, 1980Abstract Subjects from Grades 3, 4, 6, and college judged whether pairs of stimuli were identical or mirror-image reversals. One stimulus of a pair was presented upright; the other was rotated 0 to 150° from the standard. The pairs were either alphanumeric symbols or unfamiliar, letter-like characters of the type found on the PMA Spatial Ability Test.

Mental Rotation, Mental Representation, and Flat Slopes
Cognitive Psychology, 1993The "mental rotation" literature has studied how subjects determine whether two stimuli that differ in orientation have the same handedness. This literature implies that subjects perform the task by imagining the rotation of one of the stimuli to the orientation of the other. This literature has spawned several theories of mental representation.

Developmental differences in mental rotation
Journal of Experimental Child Psychology, 1979Abstract A reaction time paradigm was used to investigate developmental differences in ability to rotate and compare imaginal representations. Third grade, fifth grade, and college students (ages 9, 11, and 20 years, respectively) were required to determine whether a letter of the alphabet was presented in its backward or normal position.

Mental rotation of tactile stimuli
Cognitive Brain Research, 2002When subjects decide whether two visual stimuli presented in various orientations are identical or mirror-images, reaction time increases with the angular disparity between the stimuli. The interpretation of this well-known observation is that subjects mentally rotate images of the stimuli until they are in congruence, in order to solve the task.

The advantage of mentally rotating clockwise
Brain and Cognition, 2011The time taken to decide whether a character is shown in its mirror or normal version has been shown to increase approximately linearly with the angular departure from an up-right position. Additionally, in some studies, decisions took longer for clockwise tilted characters than for counterclockwise tilted ones.

Mental Rotation and Age Reconsidered
Journal of Gerontology, 1981Research has established that subjects required to identify tilted patterns do so by first rotating them mentally into an upright position. Gaylord and Marsh (1975) found that the rate of mental rotation of elderly subjects was 84% slower than young subjects.

Mental Rotation, Age, and Conservation
The Journal of Genetic Psychology, 1989Les auteurs reexaminent les relations entre une tache de rotation mentale et la conservation afin de tester l'hypothese de Piaget et Inheldex (1988) selon laquelle des enfants de niveau pre-operatoire ne peuvent pas se representer le mouvement en imagerie ...
