5. Laterality - types, ontogenesis of laterality

5.4. Diagnosis of laterality

Laterality - types, diagnostics

genotype - phenotype

types of laterality (combination of hand and eye laterality):

agree - disagree (crossed) - indefinite (ambidexterity)

R - R  R/ A  R X L  A / R  A / A  A / L  L X R  L / A  L - L

R right, L left, A ambidexterity

Diagnostics - dextrity coefficient DQ:

laterality bands:

pronounced right-handedness (DQ = 100 - 90)

less pronounced right-handedness (DQ = 89 - 75)

ambidextria - undefeated laterality (DQ = 74 - 50)

less pronounced left-handedness (DQ = 49 - 25)

pronounced left-handedness (DQ = 24 -0)
