The Importance Of Development Psychology

Development psychology is referred to as the “The branch of psychology that studies the patterns of growth and change that occur throughout life”. Development psychology makes it easier to understand the life span of a human being. Development psychology plays a huge role in the field as many “biologists, sociologists, anthropologists, physicians, and also historians shows a great interest in this field because it is multidisciplinary and it helps to understand both Human and animal development. Shaffer and Kipp (2010)

Human development researchers depend on research findings. Important fact about research is that it helps to answer many practical questions people ask about development begin with” it depends” Boyd and Bee (2013) For instance

In correlational research, two sets of variables are examined to resolve whether they are associated, or “correlated.” (understanding psychology) “The stability and direction of the relation among the two variables are represented by a mathematical statistic known as a correlation formally, a correlation coefficient), which can range from+1.0 to –1.0.” an example for correlation is the study where Stevenson and his colleagues (Chen & Stevenson, 1995; et a el) used the correlational research method to do an experiment on the academic environment of schools in Japan, Taiwan, and the United States.There were Many variables which was judged as they naturally occurred for instance “children 's mathematics achievement, number of classroom hours spent on instruction in mathematics and language arts, time spent in off-task activities, and time spent listening to the

Crook and West arranged an "everyday" memory situation, where the participants have to learn the names of faces of people introduced to the subjects on videotape. People from different age groups ( 18 to 90 years) viewed either 4, 6, or 14 sets of names and and learned them. The researcher measured the number of subjects who said the name correctly. Adults With the of 70 to 90 years found it very hard to even remember a small set of names .The study is crucial because it presents that it is normal for adults to be challenged by the everyday task of learning names of people whom they are they are introduced to. ( Brown,1999, Cozby Kee ) one of the main strengths in correlation research is that it Offers understanding into relationships between variables and of the main weakness is that it does not resolve causality.

Some of the other research methods are surveys. Survey method is where interviews, questioners are used to gather information quickly Boyd and Bee (2013). For example a sample of few voters is sufficient enough to predict the percentage points of who will win a presidential election if the representativesample is done methodically. (Groves et al., 2004;) a limitation of this study is that if the sample of individuals who are surveyed is no intreset on the representative of the broader of population the consequences of the study will have small
