Abstract excerpt

We examined the genetic architecture of a Tower of London test of planning and problem-solving in 690 middle-aged male twins. Phenotypic analyses revealed only one general factor, but the best-fitting genetic model indicated two correlated genetic factors: speed and efficiency. One variable-number of attempts required to mentally figure the puzzles-loaded on both factors. Shared environmental effects could be...
