title: How many camels are there in Italy? Cognitive estimates standardised on the Italian population.
abstract: OBJECTIVE
  We provided the standardisation of a new Cognitive Estimation Task (CET).
  
  
  METHODS
  the test was administered to 175 healthy subjects.
  
  
  RESULTS
  performance on the Cognitive Estimation Task (CET) is associated with gender (where women show poorer performance than men) and education (where more highly educated individuals show better performance compared to individuals with lower levels of education). However,CET performance is not associated with age.
  
  
  CONCLUSIONS
  the lack of age effects on the CET may be explained by the task dependence on "crystallised intelligence", which is less affected by healthy adult ageing than "fluid intelligence".
