Question 1 : Describe how psychologists try to improve the human condition by applying social psychological principles to social problems.

Social psychology is the study of how human beings behaves, and feel in a group setting. It is an to important aspect as it help humans understand the feelings they have as well as prepare them on how to deal with societal problems and challenges.

Question 2 : Identify at least three crucial stress factors for space travelers, and discuss how studying those problems can help people on Earth.

Space travellers go through a lot of challenges in their quest to travel across space. The risks they go through in their journey can be categorized into five significant stresses which include gravity fields, isolation and hostile environment, closed environments, space radiations and the long distances they have to cover from Earth. Studying these problems can play a huge role for people on Earth, especially those interested in travelling through space to know what to expect and how to deal with them when they arise (Angelo, 2013). Learning about these stress factors prepares space travelers efficiently for their journey as they know what to expect and how to handle every situation appropriately.

Question 3 :Define peace psychology and conflict negotiation.

Peace psychology is a branch of psychology and peace that focuses on aspect such as peace, conflict and violence among others. This type of psychology is characterized by four pillars which are directly linked to each other namely research, education, practice and advocacy.

Conflict negotiations is when two or more persons who have been aggrieved accept to have a sit down and try find a solution that would be favorable for both parties.In most cases, conflict negotiation is reached when other forms of conflict resolution have failed and allowed each party to state how they feel how they would love the matter to be resolved.

Question 4: Describe the problems faces by legal professionals when children serve as eyewitnesses.

Today it is accepted that children can serve as eyewitnesses in the court of law. However, this comes with a lot of burden on the legal professionals as in severe cases; the court is more likely to consider adult witnesses to be more reliable than that of a child (Sloane, 2017). The court is of the view that the ability to extract meaning develops slowly; hence, there could be a child's tendency to forget the accurate information of what happened. It is also equally challenging to get the same account of events from children in instances where a case takes quite a long period of hearing.

Question 5: Identify several signs that people are not getting enough sleep and identify the risks associated with sleep deprivation.

The most common signs that show people are not getting enough sleep include yawning from time to time, being moody and easily irritable, constant fatigue, they look quite depressed, it becomes tough for people to learn the new concept as their brain is tired and finally inability to concentrate for an extended period.

Sleep deprivation has many risks, including draining the mental ability and putting one's physical health at real risk. Sleep deprivation has been linked to numerous health issues such as weight gain and weakened immune system among many others. One of the other effects of lack of sleep is risk of a heart disease (In Grandner, 2019). This is so because lacking sleep may increase blood pressure thus increasing the levels of chemicals that are linked to inflammation which both have a role in heart diseases. Lack of sleep has also been attributed to weight gain, which may lead to obesity.
