Most studies employing three-dimensional objects as stimuli have used simultaneous presentation whereas most studies employing two-dimensional objects have used comparison of a single visual stimulus with a memory presentation. We suspect that it is this procedural difference rather than the difference in dimensionality that is the principal determiner of rate of mental rotation.

I have always used rather large execution squads, since I declined to use men who were specialists for shots in the neck (Genickschussspezialisten). Each squad shot for about one hour and was then replaced. The persons who still had to be shot were assembled near the place of the execution, and were guarded by members of those squads, which at the moment did not take part in the executions.
Paul Blobel
To take something from a person and keep it for oneself: that is robbery. To take something from one person and then turn it over to another in exchange for as much money as you can get: that is business. Robbery is so much more stupid, since it is satisfied with a single, frequently dangerous profit; whereas in business it can be doubled without danger.
Octave Mirbeau
One of the most extraordinary things about industrial society of the present day is its idiot lack of memory. Tabloids and movies take the place of mental processes and revolts, crimes, despairs pass off in a dribble of vague words and rubber stamp phrases without leaving a scratch on the mind of the driven instalment-paying, subway-packing mass.
John Dos Passos
If it were possible adequately to present the whole of a culture, stressing every aspect exactly as appears in the culture itself, no single detail would appear bizarre or strange or arbitrary to the reader, but rather the details would all appear natural and reasonable as they do to the natives who have lived all their lives within the culture.
Gregory Bateson
I greatly doubt whether the men who become pirate chiefs are those who are filled with retrospective terror of their fathers, or whether Napoleon, at Austerlitz, really felt that he was getting even with Madame Mère. I know nothing of the mother of Attila, but I rather suspect that she spoilt the little darling, who subsequently found the world irritating because it sometimes resisted his whims.
