The four methods viewed were: 1) Percentage of Consonant Correct (PCC) 2) Whole Word Match 3) Phonological Process Analysis 4) Nonlinear Scan Analysis.
Greiningarleiðirnar fjórar sem skoðaðar voru eru: 1) Hlutfall réttrar samhljóðamyndunar (e. Percentage of Consonant Correct; PCC) 2) Samsvörun orða (e. Whole Word Match) 3) Hljóðferlagreining (e. Phonological Process Analysis) 4) Ólínuleg hljóðkerfisgreining (e. Non-linear Phonological Scan Analysis) Þátttakendur rannsóknarinnar voru 32 íslensk börn á aldrinum 3; 1-4; 3 ára.
