Functional Neuroanatomy of Mental Rotation

Journal of Cognitive Neuroscience, 2009
Abstract Brain regions involved in mental rotation were determined by assessing increases in fMRI activation associated with increases in stimulus rotation during a mirror-normal parity-judgment task with letters and digits. A letter–digit category judgment task was used as a control for orientation-dependent neural processing unrelated ...

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.

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 ...

What is rotated in mental rotation?

Journal of Experimental Psychology: Learning, Memory, and Cognition, 1984
Two hypotheses regarding mental rotation were contrasted. If subjects rotate each stimulus image to the upright (the image rotation hypothesis), then response time should depend solely on the extent of angular deviation from the upright. But if subjects rotate their frame of reference to match that of the disoriented stimulus (the frame rotation ...

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.

Deconstructing mental rotation.

Journal of Experimental Psychology: Human Perception and Performance, 2014
A random walk model of the classical mental rotation task is explored in two experiments. By assuming that a mental rotation is repeated until sufficient evidence for a match/mismatch is obtained, the model accounts for the approximately linearly increasing reaction times (RTs) on positive trials, flat RTs on negative trials, false alarms and miss ...

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.

Mentale Rotation und Rotationsnacheffekt: Nachweis des kontinuierlichen Bewegungscharakters mentaler Rotation

1997
Prasentiert man Probanden Buchstaben in unterschiedlichen Orientierungen und last sie entscheiden, ob es sich unabhangig von der Orientierung um einen normalen oder einen spiegelbildlichen Buchstaben handelt, so dauert diese Entscheidung umso langer, je mehr der Buchstabe von seiner aufrechten Position abweicht (Cooper & Shepard, 1973). Aufgrund dieses

Practising mental rotation using interactive Desktop Mental Rotation Trainer (iDeMRT)

British Journal of Educational Technology, 2009
Abstract An experimental study involving 30 undergraduates (mean age = 20.5 years) in mental rotation (MR) training was conducted in an interactive Desktop Mental Rotation Trainer (iDeMRT). Stratified random sampling assigned students into one experimental group and one control group.
