Piaget's 3-mountains task with impossible options: Sighted, blindfolded, early and late blind participants.

In Piaget's 3-mountains task, 3D objects - a cube, cone and sphere - sit on a square tabletop. They are portrayed in 2D pictures as (projections to the sides) such as one with a square on the left, a triangle in the middle and a circle on the right. Three objects offer six elevations, of which four are possible and two impossible.

5-Aroylindoles Act as Selective Histone Deacetylase 6 Inhibitors Ameliorating Alzheimer's Disease Phenotypes.

This paper reports the development of a series of 5-aroylindolyl-substituted hydroxamic acids. N-Hydroxy-4-((5-(4-methoxybenzoyl)-1 H-indol-1-yl)methyl)benzamide (6) has potent inhibitory selectivity against histone deacetylase 6 (HDAC6) with an IC value of 3.92 nM.

Metaphoric Car Drawings By a 12-Year-Old Congenitally Blind Girl.

A 12-year-old congenitally-blind girl drew a car moving, stationary, and braking. For stationary, she put the wheels inside the car and, for braking, drew the wheels as rough rectangles. At the age verbal metaphor is understood (Winner, 1988), the girl invented metaphoric drawings.

Elevation easier than plan for sighted and early-blind adults in a perspective-taking task.

Plans show shapes of objects from above, and represent both their left-right order and their order in the z-dimension (the distance of the objects). Elevations show only the vertical shapes of objects arranged from left to right. Plans, having more spatial information, may be more difficult for participants to construct.
