The article examines the problem of deprivation analysed as a multifactorial psychological phenomenon that has a significant negative impact on children's personal development. The nature of deprivation is determined depending on the factors that generate it, namely, biogenic, sociogenic and psychogenic.
 The phenomenology of biogenic deprivation is revealed, its features and consequences for children's psychosocial development are characterized.
 We have determined that if a certain organic violation exists, there are always leading and concomitant types of deprivation. Accordingly, each violation basically causes a certain leading deprivation; and this fact allows us to derive a certain typology of biogenic deprivation.
 Visual deprivation occurs at visual impairments, auditory deprivation does at hearing impairments, mental deprivation appears at intellectual development impairments (feeble minding), cognitive impairments does at cognitive development impairments (mental retardation), speech (communicative) one does at speech disorders, motor one does at musculoskeletal system disorders, deprivation of identity (social one) does at autistic spectrum disorders.
 All types of deprivation have some common manifestations, namely: increased anxiety, decreased vital activity, frequent mood swings, unmotivated aggression, etc.
