24A health warning!Apart from what a child ‘does’, we need to take account of:The characteristics of a particular childTheir immediate environmentTheir family context and its social natureTheir cultural context: social implicationsHow the same child varies by setting
25…and another health warning! More broadly we need to be mindful of:How the developmental course varies for different individuals in:similar settingsdifferent settingswith the same peoplewith different people
26OK!... Another warning! We always need to ask: ‘How our developmental expectations affect our interpretation of what we observe?’‘How the expectations of others may affect their interpretation of what they observe?’
27Kathleen Berger (2000)The typical (usual) patterns of growth and change are ones everyone follows to some degree but no one follows exactly
28Typical and atypical development Five broad groups of contexts linking typical and atypical children:1 Delayed development2 Atypical development3 Compensatory development4 Absence of development5 Typical behaviour displayed by atypical children
29Atypical development 1 1 Delayed development Development is slower than typically developing children. Similar processes are shared, involving the same stages. Atypical children may not develop to the same extentBased on Herbert, M. (2003) ‘Typical and Atypical Development’ Oxford: BPS Blackwell. p.xiii
30Atypical development 2 2 Atypical development The processes of development differ to those found in typical children - as a result behaviours and developments not seen in typical children may be apparentBased on Herbert, M. (2003) ‘Typical and Atypical Development’ Oxford: BPS Blackwell. p.xiii
31Compensatory development Atypical development 3Compensatory developmentHere the same developmental end point is reached but the route taken by atypical children is different to that taken by typically developing childrenBased on Herbert, M. (2003) ‘Typical and Atypical Development’ Oxford: BPS Blackwell. p.xiii
324 Absence of development Atypical development 44 Absence of developmentChildren fail to develop a particular aspect of developmentBased on Herbert, M. (2003) ‘Typical and Atypical Development’ Oxford: BPS Blackwell. p.xiii
335 Typical behaviour displayed by atypical children Atypical development 55 Typical behaviour displayed by atypical childrenHere atypical children display typical behaviours and development: the atypical child may show typical development, developing within the range of variation noted for typical development.Based on Herbert, M. (2003) ‘Typical and Atypical Development’ Oxford: BPS Blackwell. p.xiii
34Issues linked to ‘milestones’ 1 When milestones occur - taking account of range and underlying variationExpectationsImpact of cultural variation
35Issues linked to ‘milestones’ 2 Impact of cultural variationChild-rearing practicesThe equivalence of expectations from different professional perspectivesDifferent periods, different judgements: e.g. height and physical maturity
36Specific issues: VI and milestones 1 Parent –child interactionImportance of visual feedbackMotor activity and movementFocus on child touch and hand movementsFocus on listening by childCompensatory communication routes
37VI– developmental focus areas Movement perceptionPerceptual-motor skillsGross motor skillsFine motor skillsUseable visionSize constancyShape constancyFace recognitionDepth perception
38Child development theories 1 Historically:Childhood: the early part of being an adult - not a special periodChildren as little adults – no special care or attention required; no differentiation between ‘child’ development and ‘adult’ development
39Child development theories 2 Arnold Gesell ( ): universal patterns of physical maturation, genetically driven and determined > ‘milestones of development’Sigmund Freud ( ): early childhood experience informs subsequent development; focus on impact of psychosexual influences > type of stage theory
40Child development theories 3 Erik Erikson ( ): extends Freud’s perspectives:Brings in environmental factors and more stages issue of overcoming stage related ‘crisis’ events.B.F. Skinner ( ): Child behaviour shaped by how experience is reinforced:Role of reward and punishment > experience conditions behaviour
41Child development theories 4 Alfred Bandura (1925 -present): Learning informed by imitation and social observationRole of motivation and inner psychological processesmodelling, role models, ‘social’ learning: ‘Social Learning Theory’
42Child development theories 5 Lev Vygotsky ( ): Learning interactions as basis of development:Role of social context, language, communication and the mediating influence of others inform a ‘social constructivist’ developmentHistorical, cultural and social factors inform cognition and development - ‘language’ is the principal societal tool
43Child development theories 6 Jean Piaget ( ): development seen as:Four, genetically driven, universal and sequential stages of symbol based ‘cognitive’ development.These reflect children's individual construction of their own thinking systems, supported by interaction with adults
44Child development theories 7 John Bowlby and Mary Ainsworth (Integrated Attachment Theory):focus on how parent – child relationships are establishedthe role of early relational experiences and their impact on how later relationships are formed and maintained‘Life Course’ perspectives: re-integration of child and adult development as aspects of a single developmental continuum

50Short-SightednessAlso known as Near-sight or Myopia, short-sighted individuals have trouble seeing things in the distance whilst anything close-up is clearer. This occurs because light from the objects being viewed focuses in front of the retina and not on it. It is believed that this mostly happens as a result of the eyeball being slightly too long. The scientific term for this is Axial Myopiadownloaded at 4.15pm
51Long-SightednessAlso known as Far-sight or Hyperopia, long-sighted individuals have difficulty with anything close-up whilst their general distance vision is not as bad. Light from objects viewed will theoretically focus behind the retina and not on it. However because the eye is able to naturally fatten the lens and cause light to bend more, this error in focus is overcome, which explains why distance vision is generally pretty good.From: downloaded at 4.15pm
