As Professor Oatley points out，our emotions have very important functions，for example，fear.If we cross the road and a car approaches，we usually stop moving or step back.We stop what we are doing，check what we have done and pay very careful attention to the environment.The emotion of fear makes us take this small series of actions which，on average，help preserve our safety.
On the other hand，if things are going well and small problems come up，we find we can solve them with the resources we have to hand.As a consequence，we tend to feel happy and usually continue doing the job.
Anger is an emotion that tends to occur when someone is preventing us from doing something.Then this small “kit” of reactions enables us to prepare ourselves to be quite aggressive to that person，or to try harder，and so on.
Professor Oatley believes emotions generally occur at these important moments in actions.With fear and anger our emotions make us decide to start doing something else，while with happiness they “suggest” we continue what we are already doing.
