Williams, Thomas O., Jr.; Ernst, Jeremy V.; Kelly, Daniel P.; Clark, Aaron C. – Engineering Design Graphics Journal, 2019
The Purdue Spatial Visualization Test: Visualization of Rotations (PSVT: R) is a widely used assessment of spatial ability. In this report, the factor structure of the PSVT: R test items was examined through confirmatory factor analysis with data from 541 engineering design graphics students. Stata 15 and Mplus 8.2 statistical software were used…

Ernst, Jeremy V.; Willams, Thomas O.; Clark, Aaron C.; Kelly, Daniel P. – Engineering Design Graphics Journal, 2017
The Purdue Spatial Visualization Test: Visualization of Rotations (PVST:R) is among the most commonly used measurement instruments to assess spatial ability among engineering students. Previous analysis that explores the factor structure of the PSVT:R indicates a single-factor measure of the instrument. With this as a basis, this research seeks to…

Ernst, Jeremy Vaughn; Lane, Diarmaid; Clark, Aaron C. – Engineering Design Graphics Journal, 2015
The ability to rotate visual mental images is a complex cognitive skill. It requires the building of graphical libraries of information through short or long term memory systems and the subsequent retrieval and manipulation of these towards a specified goal. The development of mental rotation skill is of critical importance within engineering…
