The 24 spatial problems in the TFG Revision 2004 are a revised version of Space, Time and Hyperspace, a subtest of the Long Test For Genius. Four less satisfactory problems have been removed and several other problems have been slightly revised to better lock in the solutions (there were often complaints about "too many possible answers").
As a result, this spatial section is somewhat easier than the earlier version (raw scores are not directly comparable between the old and new versions) and should have greater reliability and validity. It is not used as a test in its own right currently, but the below norms and statistics are informative if one has taken the TFG Revision 2004 and wishes to know how one did on the spatial section.

Ranking in above table is based on the unrounded correlations. All available data is present in this table, no tests are left out except for those with less than 5 score pairs. All known pairs are used to obtain the true, honest statistics; Correlations are not artificially inflated by leaving out ceiling scores, outliers or other anomalies.

Correlation of this test with national average I.Q.s published by Lynn and Vanhanen:
In parentheses the number of score pairs on which that estimated g factor loading is based (For maximum sensitivity, all other tests are used for which at least two pairs are available). The Upward and Downward values are calculated including the pertinent score itself. It is normal that g factor loadings go down when the range is restricted like this, but careful study of the Upward and Downward columns may reveal possible scores below or above which the test loses validity altogether.
