0-3 Years Intellectual Development

Between 0-3 years there is a lot of change in intellectual development, at birth a baby blinks in reaction to bright lights, turns to soft lights and will cry when basic needs require attention. And by 3 months they can follow movements of a large or smaller object.
Between 6 and 9 months children are very curious and easily distracted by movements, immediately fixes sights on small objects that are close by and reaches out to grasp them and watches toys fall from hands that are in range of their vision.
Between the ages of 1 and 2 a child will look in the correct place to where an object has fallen or rolled out of sight, and can recognise familiar people at about 6 meters. They can turn pages in a book and can point to named objects, parts
By this stage I their development a child will be able to draw a man with a head, body arms and legs. They can colour pictures neatly, name primary colours and matches 10 or more colours. They will be able to copy a range of letters and count up to 20 on their fingers. They will be able to relate to times of day including breakfast, lunch and bed time etc. They also begin to understand about sameness and differences in various aspects of life.
Between the ages of 7-12 a child develops the ability to think of several things at once, they begin to show preference for certain subjects and hobbies. Their reading and writing will develop with greater confidence and they will also be able to transfer information from one situation to another.
Between the ages of 12-19 years they will have clear preferences for subjects and will make decisions related to their GCSE and A level subjects. Also their career choice will be being thought about at this stage. During this time which is known as adolescence young people increasingly take personal responsibility for finances, accommodation, employment, and interpersonal relationships. Career and university choices will be made based on exam results and personal preferences.
Language
They can hold a pencil steadier and copy shapes, follow instructions without having to stop what they are doing and hear and understand nearly everything that is said to them at home.
Between 5 and 7 years their speech will become more fluent and correct, they rely less on pictures and objects to learn new words and can handle books well. They can share and discuss more complex ideas and use language in a range of social situations.
At the ages between 7-12 years a child’s vocabulary will grow if adults introduce new words and new ways of using language and keep conversations going by giving reasons and explaining choices, but they will need help in tackling the complexities of spelling. They will be able to read out loud, speak fluently and describe complicated happenings.
Children aged 12-19 become increasingly independent and spend much of their day outside the home. They will have a fast legible style of handwriting, communicate in an adult manner and understand abstract language. They can start being sarcastic and this can be irritating but they are just testing out their new sophisticated language skills. They may start debating formally or informally, but this also is just a sign of the language development
