 So, causes of individual differences are very important to consider because these causes we need to understand that why we are getting differences and we need to actually either we need to control these causes either we need to manipulate these causes and either we need to just improve our personalities whatever the forces are influencing you but we need to just you know make ourselves more strong and more positive and more comprehensive personality we need to just convert ourselves. So, basically what is the what does it mean the causes of individual differences we first of all we must accept these differences that these differences are natural these differences are from God side and and although the environment you have created the environment and you actually born into the in in the family that family is actually giving you the environment that is making difference into your personality but you know environment is in your hand you can change your environment and then the all more all those powerful forces that are bringing negative change into your personality then you can manipulate. So, hereditary factors although we cannot change we cannot change the characteristics in our genes but believe me we can polish our these characteristics because if you got aggressiveness from your father side and you are aggressive because in it is in your genes. So, how can we how can we accommodate with this characteristic yes if we will provide better environment better atmosphere at house and if the house environment is peaceful and the child is seeing that the parents are very friendly honestly speaking the parental conflict it always bring negative effect on your child's personality you are quarreling that parents are quarreling children are observing and then they are actually because they are helpless they cannot change their parents. So, they need to just accommodate with themselves. So, what they what they are thinking why why children are aggressive first of all that you are giving them the atmosphere from your house. So, parents should control themselves to just show a good model to the to their children and it is theoretical perspective that I am sharing it is practical perspective that I am sharing I am I am also sharing with you from the observation and experiences. So, you should consider it very important to bring peaceful environment from your house because the child's personality is growing up and you can change the personality of your child it is in your hand if hereditary perspective is not very strong child is not very intelligent then you can provide the better environment to your child to make him more make him more successful in the society it is in your hand believe me if we if we compare the hard worker and and the genius child then the genius has already a God gifted ability so he can prosper in every field of life but if you will provide the better opportunities to your child better books for reading better environment peaceful environment child needs peaceful environment at house because the first ideal of the child are parents. So, through the financial crisis parents should not quarrel with each other then that would be the most you know positive environment you can provide to your child financial matters are also very important but your child is not concerning with your financial crisis. So, don't put your crisis on to your child that is very important advice that I am suggesting here and so these are the causes that is basically bringing change into the personality of the child sometimes you are ignoring your middle ones and you are giving more attention to your elder one you are giving more attention to smaller one younger one and then this number you know in psychology the number of child is very important why the number of child is very important because it bring change into the personality. So, for individual differences the number of child is very important and in many families you know people ask when they just try to get proposal for their children then they ask that the word number of the male is here because the first child is experimental child and parents always do experiments on the first child. So, first child is called experimental child the middle ones are ignored children and the smaller one is you know overly emphasized child. So, number is very important in psychology education to understand the personality of a child and because according to the inner culture according to the number we treat our children that's why it brings change into the personality of the child. So, parents should be very careful and don't ignore your children and you should give the equal attention to your children then otherwise children will get rivalry feelings and one brother can get this feeling and it will you know continue till the adulthood and even they will you know they will just argue with their parents that you are ignoring me from the childhood till now you are giving more attention to the elder one and you are giving everything to the elder one but you are ignoring us. So, it will create aggressiveness in the children. So, I am basically actually talking about the causes. So, these are the causes that we are providing from the environment of our house you it is in your hand you can control all these things and don't give the thinking to your child that he is ignored or if somebody is getting more attention that is you know comparison this comparison can bring change into the personality of your child. So, physiological changes also here and physiological changes that we cannot control that physiological changes that in body weight but you can control what you can control you cannot stop the height but you if you are giving the good food to your children then they will get better you know health and we can also control our weight that is in our hand. So, how can we control physiological you know factors to minimize the differences in the personalities and innate ability learning yes innate that you get good intelligence from your heredity. So, you are you know getting achievements and success into your life but if we if you provide the better environment study have environment to your children then they will be hard worker and sometimes hard worker beat genius children because genius children sometimes they are very careless. So, by this way you can minimize the factors that are influencing the children's personality and we also need to give the attention to the those children that those have the physiological you know differences hearing loss, visual impairment, speech difficulty and these these differences also bring change into the personalities. So, we should pay attention to these differences as well.
