Three- to 4-month-old female and male human infants were administered a two-dimensional mental-rotation task similar to those given to older children and adults. Infants were familiarized with the number 1 (or its mirror image) in seven different rotations between 0° and 360°, and then preference-tested with a novel rotation of the familiar stimulus paired with its mirror image. Male infants displayed a novelty preference for the mirror-image stimulus over the novel rotation of the familiar…

Mental Rotation in Human Infants
TLDR
Evidence is provided for a sex difference in mental rotation of an object through three-dimensional space, consistently seen in adult populations.
A Sex Difference in Mental Rotation in Infants: Convergent Evidence
TLDR
It is revealed that the sex difference in mental rotation is observed in 6- to 7-month-olds and 9- to 10- month-olds, suggesting that a sex difference is present at multiple ages during infancy.
Adults’ Sex Difference in a Dynamic Mental Rotation Task: Validating Infant Results
With the Mental Rotation Test (MRT), large and reliable sex differences are found. Used with children younger than about 9 or 10 years, MRT performance is at chance level. Simpler tasks used with
Mental Rotation of Dynamic, Three-Dimensional Stimuli by 3-Month-Old Infants.
TLDR
The data support the interpretation that mental rotation of dynamic 3-dimensional stimuli is relatively difficult-but possible-for 3-month-old males.
Preschoolers' mental rotation of letters: Sex differences in hemispheric asymmetry
TLDR
Sex differences in functional hemispheric asymmetry during mental rotation do not require hormonal changes that occur during puberty and are not found in this study.
Mental object rotation and motor development in 8- and 10-month-old infants.
Touching up mental rotation: effects of manual experience on 6-month-old infants' mental object rotation.
TLDR
It is demonstrated that 6-month-olds' mental rotations benefit from manual exploration, highlighting the importance of motor experience for cognitive performance.
Influence of Rotational Axis and Gender-Stereotypical Nature of Rotation Stimuli on the Mental-Rotation Performance of Male and Female Fifth Graders
TLDR
Overall, results suggest that rotational axis is more influential in determining the gender difference than the stereotyped nature of the stimuli.
Age and Sex Differences in Verbal and Visuospatial Abilities
TLDR
Results showed a significant Sex × Age interaction on the mental rotation task, with men outperforming women in the 3D task, but with no sex differences shown in childhood in the 2D task.

The locus of sex differences in spatial ability
College men and women judged whether pairs of stimuli were identical or mirror images. One stimulus of a pair was presented upright; the other was rotated 0°–150° from the vertical. The stimuli were
Early sex differences in spatial skill.
TLDR
Comparable performance of boys and girls on a vocabulary task indicated that the male advantage on the spatial task was not attributable to an overall intellectual advantage of boys in the sample.
Two- and three-dimensional mental rotation tasks lead to different parietal laterality for men and women.

Sex Differences in Infants' Mapping of Complex Occlusion Sequences: Further Evidence
TLDR
Sex differences in infants' capacity to map their representation of an occlusion sequence onto a subsequent no-occlusion display are observed in event-mapping tasks and the underlying basis for these differences is identified.

The effects of sex steroids on spatial performance: a review and an experimental clinical investigation.
TLDR
An experimental study of the role of actively circulating sex steroids in adolescents being treated for delayed puberty and spatial performance showed traditional sex differences but did not vary with levels of actively circulate sex steroids.
Cross-Race Preferences for Same-Race Faces Extend Beyond the African Versus Caucasian Contrast in 3-Month-Old Infants.
TLDR
The findings reported here extend the same-race preference observed in young infants to a new race of infants (Chinese) and show that cross-race preferences for same- race faces extend beyond the perceptually robust contrast between African and Caucasian faces.
