Mental rotations are more accurate when done in two dimensions than when done in three dimensions.

Mental Rotations

The cognitive process of rotating mental representations of two-dimensional and three-dimensional objects as part of spatial reasoning and visualization.

Two Dimensions

Relates to having two measurements or aspects, such as length and width, often used to describe flat surfaces or to represent ideas in a simplified form.

Three Dimensions

Pertains to objects that have depth, width, and height, contributing to their solid form.
