On ASVAR the test reveals a highly significant effect of task type ( F(2,\,15) = 274.0 , p < 0.001 ): forgery detection ( , σ = 0.24 ), biometric identification ( , σ = 0.30 ), and forgery source identification ( , σ = 0.24 ) are mutually and significantly separated (all pairwise t -tests: p < 0.001 ).
