Mental rotation in a commissurotomized subject

Neuropsychologia, 1989
The 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 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.

Effects of Mental and Manual Rotation Training on Mental and Manual Rotation Performance [PDF]

Spatial Cognition & Computation, 2014
Abstract:Previous research has shown that training can improve mental rotation performance and has found connections between mental and manual rotation. Here we examine how practice in mental or manual (virtual) rotation, affects performance on mental and manual rotation tasks, compared to a control condition.

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: an examination of assumptions

WIREs Cognitive Science, 2017
Since 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 ...

Saccades to mentally rotated targets

Experimental Brain Research, 1999
In order to investigate the role of mental rotation in the directional control of eye movements, we instructed subjects to make saccades in directions different from that of a visual stimulus (rotated saccades). Saccadic latency increased linearly with the amount of directional transformation imposed between the stimulus and the response. This supports

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 ...

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.

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.

Reference frames in mental rotation.

Journal of Experimental Psychology: Learning, Memory, and Cognition, 1987
Four experiments are reported that investigate whether images or reference frames are transformed during a mental rotation task. In all experiments a display of four identical letters (P1) was presented at either +90 degrees or -90 degrees from upright, and subjects had to decide whether the letters were normal or mirror-image reflections.
