2. Child Development
Child development is a dynamic process
Normal development is determined by a complex interplay between environmental factors, genetic factors and acquired pathology.
3. Warning Signs of Abnormal Development
Echolalia- repetitive imitation of speech- still present by 3 years.
Absoulte failure to develop skills (eg multi- syllable babble with intonation- by 10 months)
Motor asymmetry
Developmental regression- loss/ plateauing of skills
4. The Developmental Examination
History taking: family history, social and family environment, pre-, peri- and postnatal history.
Enquire into the parents concerns and seek information from others who know the child (eg. teachers, health- care staff)
5. Observation and interactive assessment
Suitable selection of toys should be made available before meeting the family and interacting with the child.
Appropriate toys for the age of the child and the domains of development to be assessed.
6. Observation and interactive assessment
Examples:
Copying behaviour (bell) and understanding of cause and effect (pop- up animal toys)
Definition by use (cup/ spoon, doll/ brush) and symbolic understanding (doll/ teddy/ tea set)
Fine motor/ eye- hand (bricks, crayons/pencil/paper, soft ball, form boards, puzzles)
Language and play (books with single pictures and stories, range of everyday toy objects, large and miniature toys)
7. Observation and interactive assessment
‘Free Play’- the child’s inability to organize the environment and generate ideas on their own will be significant.
Eg. May not be able to focus attention (flit from one object to another or repetitive play may be noted.
Cardinal rule of DA: to look not only what the child does, but also how s/he does it.
Quality of response should therefore be monitored as well as the actual achievement.

40. Visual Behaviour, eye- hand coordination and problem solving
Progressive coordination of maturing vision with head, body and fine motor movements can be observed through: manipulation and use of pellet, rings, bell, cubes, crayon/ pencil, form boards or puzzles.
Achievement in this domain represent the precursor to later non- verbal problem solving abilities, correlate well with intellectual ability and may provide early markers for learning, psychological and psychiatric disorders.
41. Co-ordinated eye movements and eye-head co-ordination
Earliest developmental sequence starts with fixing gaze on the mother’s face following a face with eyes only co- ordinate eye- head movements to turn head to follow visually
Any abnormality of early visual behaviour should prompt referral for ophthalmological assessment

59. Gross motor
Delay in achievement of the gross motor milestones may be an indicator of neurological abnormalities and is sometimes associated with a global developmental delay.
60. Development of attention
Stage I- extreme distractibility. Attention shifts from one object/ person/ event to another. Their attention is held momentarily by whatever is the dominant stimulus (Year 1)
Stage 2- children can concentrate on a task of their own choice. They are v. resistant to interference by an adult (Year 2)
Stage 3- can shift their full attention to speaker and back to task with adult support. (Year 3: ‘single- chained attention’)
61. Development of attention
Stage 4- Children begin to become able to control focus of attention. Looks at an adult only when the directions become difficult to understand (Year 4: early ‘integrated attention’)
Stage 5- Can integrate verbal commands related to a task. Attention span still short. (Year 5: mature ‘integrated attention’)
62. Development of attention
Stage 6- Fully integrated attention. Auditory, visual and physical channels are integrated. Attention is well established.(5- 6 years)
