Silver, Ned C., Kennedy, Robert S., Larson, B. M. and Ritter, Alysia D. (1995): Inter/Intra Correlations of Mental Aptitude and Computerized Visual Temporal Factors. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 897-901.

“Temporal visual acuity is studied in the laboratory using flicker, simultaneity, and dynamic visual acuity. The purpose of the present study was to develop further and examine psychometrically a battery of seven temporal acuity tests that could be used for selection and training, if they had sufficient factorial sickness and minimal overlap with existing global measures of intelligence. A sample of 56 undergraduate students completed four sessions of the temporal factors battery, the Armed Forces Vocational Aptitude Battery (ASVAB), and 24 subjects provided scores on the Scholastic Aptitude Test (SAT). Results showed that reliability was within the acceptable range for the Search, Dynamic Visual Acuity, Phi Phenomenon, Critical Flicker Fusion, and Masking. For the most part, the temporal factors battery did not correlate significantly with the highly reliable ASVAB or SAT, implying that these temporal factors are somewhat independent of a general intelligence factor. The relevance of these constructs for industrial and military tasks is discussed.”

Ritter, Alysia D., Royalty, Joel and Kennedy, Robert S. (1995): Visual Theory: Spatial and Temporal Factors. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 902-906.

“The psychometric properties of seven temporal factors (TFT) and five spatial factors (SFT) tests were assessed in a sample of 20 undergraduates. Subjects completed six repeated measures sessions of the TFTs and four trials of SFTs. All tests except Neisser's letter search produced stable measures. Reliabilities ranged from .81 to .98 for Simultaneity, Flicker, Search, and Bistable Stroboscopic Motion and from .59 to .71 for Masking, Phi, and Dynamic Visual Acuity. Of the 70 possible correlations between spatial and temporal batteries (7 TFTs X 5 SFTs X 2 distances), only four were significant. The moderate to high retest reliabilities, combined with the negligible correlations between spatial and temporal tests suggest that the two processes are largely independent.”

“Concerted efforts are made to make performance tests comparable across media. When comparing computerized test batteries, however, there may be differences in hardware and software that can produce less than optimum psychometric properties. The present study examined a battery of seven tests implemented on two computers, a Gateway 2000 P4D-33 and a 286 Zenith PC. Results showed that there were differences in performance levels as a function of trials which may be attributed to individual differences. The means and standard deviations were more stable for the Zenith than for the Gateway 2000 P4D-33. It was equivocal whether this was a function of computer or methodology. Additionally, there were no differences in cross-correlations across computerized test batteries. This finding implied that the constructs were consistent across both batteries although mean differences will need to be reckoned with. Implications and limitations for computerized testing are discussed.”
