TL;DR: In this paper, three studies were conducted to investigate effects related to age and experience on measures of spatial visualization ability and found that increased age was associated with lower levels of performance on several tests of spatial visual ability.

TL;DR: A questionnaire designed to assess experience with activities presumed to require spatial visualization abilities, and psychometric tests of these abilities, were administered to 383 adults ranging from 20 to 83 years of age as mentioned in this paper.

TL;DR: In this article, three hypotheses were proposed to account for individual differences in spatial visualization ability were investigated and the evidence was somewhat mixed with respect to the preservation-under-transformation hypothesis but it does appear that spatial visualization differences are most pronounced when some information must be preserved while the same or other information is being processed.

TL;DR: Salthouse et al. as mentioned in this paper explored a distinction between structural capacity, the maximum number of informational units that can be temporarily stored, and operational capacity, which is the number of processing operations which can be executed while simultaneously preserving the products of earlier processing.
