Mental Rotation, Mental Representation, and Flat Slopes

Cognitive Psychology, 1993
The "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.

On Mental Rotation in Three Dimensions

Perceptual and Motor Skills, 1997
Real three-dimensional models and three-dimensional images were used in a test of mental rotation. Although the 33 men performed better than the 33 women when presented three-dimensional images (14.4 and 11.2), this sex difference disappeared when real models were used (17.5 and 17.3).

Mental Rotation by Neural Network

2009 Fifth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2009
This 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 ...

Developmental changes in mental rotation

Journal of Experimental Child Psychology, 1980
Abstract 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.

Developmental differences in mental rotation

Journal of Experimental Child Psychology, 1979
Abstract 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, 2002
When 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, 2011
The 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, 1981
Research 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, 1989
Les 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 ...

In touch with mental rotation: interactions between mental and tactile rotations and motor responses

Experimental Brain Research, 2017
Although several process models have described the cognitive processing stages that are involved in mentally rotating objects, the exact nature of the rotation process itself remains elusive. According to embodied cognition, cognitive functions are deeply grounded in the sensorimotor system.
