Development: this term is normally used to describe changes that might be complex and involve a change in the quality of some ability for example, Lionel Messi’s shooting ability developed during the course of his career. He is now more prone to taking shots outside the box. Development could be a change in measured quantity such as Messi’s height or weight. The changes in the Messi’s social, intellectual and emotional aspects of his life are described in terms of development.
Growth: This is usually confused as having the same definition as development however, that is not case. Growth is an increase in a measured quantity. For example height or weight.
Developmental norms: These are expectations/standards by which the progress of a child's development can be measured. For example, the average age at which a child walks, learns to talk, or reaches puberty would be such a standard and would be used to judge whether the child is progressing normally.

Developmental milestones: These are milestones are behaviours or physical skills seen in infants and children as they grow and develop. For example, a baby rolling over is considered as a milestone. The milestones are different for each age bracket.

INFANCY 0-3 YEARS

Lionel Messi was born with growth hormone deficiency. This is when the pituitary gland does not make enough growth hormone. Which means during his development in the womb and infancy he was slow in growth development. This would have meant the Lionel Messi would reach life milestones such as lifting his head at 3 months at a later stage because the muscle needed to perform that developed later than normal. This may have led to him reaching his developmental milestones later. For example, being able to lift his head at 0-1 months
CHILDHOOD 4-9 YEARS
He would of had delayed development during his childhood due the growth hormone deficiency. As you can see from the picture he was much smaller than his peers, which is evidence of his delay.

ADOLESCENCE 10-18 YEARS
It was during this time that Messi was diagnosed with the condition. This means this is when the treatment was started for him. So perhaps his early years of adolescence was delayed. This mean he may have hit puberty later than others around his age.
ADULTHOOD 19-65 YEARS
During the early stages of adulthood Lionel was receiving the treatment needed to cure him of his condition. This means by this time he would have caught up in the physical development and developed normally alongside his peers and colleagues. However, Messi is only 5ft6.5 which is considered to be below the average height for his age.
OLDER ADULTHOOD 65+ YEARS
Lionel Messi currently 27 however, I could predict the physical development that he could possibly go through at the later stage of life. A range of processes may limit his lifespan. For example, during this stage Messi’s body cells have a limited ability to renew themselves. This means that his body cannot repair itself and stay healthy. During late adulthood his senses being to deteriorate slowly.

Social development
Infancy 0-3 years: I could not obtain the social development of Lionel Messi as an infant so could only assume that he developed normally. For example, Messi will start to enjoy routines (bath time, feeding and sleeping). He would have also discover sensorimotor at the end of infancy e.g. waves, cries when left on their own, copies actions of adults. He spent a lot of time with his mother so he would had developed good social skills.
Childhood 4-9 years: Messi may have not developed socially efficiently in comparison to the norm. This is because of his condition. His peers could have found it weird that he was shorter than the majority. This could have knock his confidence thus delaying the process of learning to share because of friends and siblings. The number of people that children know will begin to expand because of the friends that they will make during school. They also begin to compare themselves to other people when they reach this life stage.
Adolescence 10-18 years: At age 11 Lionel left his home in Argentina to go to Barcelona in Spain to become a footballer. Therefore would have become more independent and experimental. He would have also develop the skills to negotiate with peers and adults. However, I believe that Messi could have started to negotiate later due to lack of confidence because of his size.
ADULTHOOD 65+ YEARS: Mature adults may have to split their time between work, care of parents, other family committees and wider social activities

INTELLECTUAL DEVELOPMENT

INFANCY 0-3 YEARS
Lionel Messi condition did not have an effect on his intellectual development as an infant. This means that he developed normally. Research shows that Messi had rapid intellectual development. From birth to about 2 years is a period of
During this stage he used ‘trial and error’ in order to learn. Prior to the trial and error stage, he would have normally depended on his reflexes.

CHILDHOOD 4-9 YEARS
Research shows that egocentrism is still very present at this stage of the Messi’s intellectual development.
During this stage children begin to display ‘animism’. This means that they incapable of realising that inanimate objects do not have human capabilities (e.g. feelings)

ADOLESCENCE 10-18 YEARS
It was during this stage the Lionel Messi began to think logically and developed abstract thinking. By this age Messi had the ability to solve algebraic equations

ADULTHOOD 19-65 YEARS
During this time there isn’t that much intellectual development going on except from Messi’s experiences having an effect of his abstract thinking. This evidence through the change in his approach to football.
Messi is still in the adulthood stage of his development. Therefore, I can only assume what changes he will goes through intellectually during older adulthood

ADULTHOOD 65+ YEARS
Messi is still in the adulthood stage of his development. Therefore, I can only assume what changes he will goes through intellectually during older adulthood.

EMOTIONAL DEVELOPMENT

INFANCY 0-3 YEARS
Messi’s mother being a part-time cleaner means that he got spends a lot of time with her. Messi most likely had a secure attachment. This sets him up with the emotional resources needed to cope with the uncertainty of life.

CHILDHOOD 4-9 YEARS
Children use their imagination to begin to understand the social roles that other people play. Children begin to imagine a ‘me’- an idea of self. Relationships with other family members may influence how a child feels valued.

ADOLESCENCE 10-18 YEARS
The sense of self continues to develop. An adolescent needs to develop a secure sense of identity. Identity theory was first proposed by Erikson (1963). A person needs a clear understanding of identity in order to feel secure when working with other people or in order to make a loving sexual attachment.

ADULTHOOD 19-65 YEARS
The key task of adulthood was learning to cope with emotional attachment to a sexual partner. This may involve not being too self-centered or defensive and not becoming emotionally isolated. This is evident in Messi’s case because in 2008, he got married to Antonella Roccuzzo and then went on to start a family.

ADULTHOOD 65+ YEARS
Older people need to develop a secure sense of self that enables them to cope with the physical changes associated with ageing and death. People who fail to make sense of their life might experience emotional despair.

Pregnancy

This begins when the fertilised egg cell start to divide, after two or more days the fertilised egg would have grown to the size of a pin head. After 8 weeks the foetus would have grown 3-4cm and the eyes, ears, mouth, arms and legs would have started developing. The development of the foetus will continue throughout the pregnancy.

When the baby is conceived the brain and the organs start to develop after seven or eight weeks. After four to five months the baby can begin recognising their motherâs voice and sounds they like and donât like.

Babies begin developing emotional feelings after six months of being in the womb as they are able to recognise the motherâs voice and sounds from the outside of the body. The motherâs moods can affect the childâs emotional state whether she sad, happy or stressed as the child can sense her mood.

The child does not have many ways of socialising with others in the womb. The only way the child is able to socialise in the womb is if thereâs more than one child i.e. twins, triples etc. where they can interact with one another in the womb. The foetus can also respond to touch, sound and the mother, this is also another way for a foetus to socialise from the inside.
