Lateral characteristics of 128 males (aged 20-35) with colour percepti
on anomalies and of 276 healthy ones with similar social status were s
tudied. Among persons with colour perception anomalies there is reliab
le accumulation of left-handed subjects and those with left index of <
<crossing of hands>> test. It is assumed that genesis of colour percep
tion anomalies is connected not only to peripheral retinal anomalies b
ut is due to central disfunction of pre- and perinatal character. Late
ral criteria can be used in vocational consultation.
