I avoided observational bias by not speaking with the child before or during my observations and restricting myself to simple questions when speaking with him. By avoiding contact until after the observation periods, I avoided any attempts on my part to influence the outcome of this study by trying to manipulate the child into behaving and creating to support my opinions.I didn’t choose the subject beforehand so I knew nothing about him until I spoke with his teacher after my final observation was completed. I chose the child that occupied the most central seat in the class, but I could have used any number of other criteria to choose a subject. I came up with these criteria before entering the class for the first time. I had no idea whether my subject would be male or female, what their age would be, or what their other physical and mental characteristics would be.Upon completion of the study, I found that my hypotheses were incorrect. Though psychosocial, cognitive and biosocial developments are interrelated, I focused on the biosocial domain while conducting and documenting this study.The average 4-5-year-old, regardless of sex or race, is active and consumes and uses about 1,700 calories per day, and sleeps ten to eleven hours at night. They have gained greater control of their gross motor skills which enables them to run, skip, hop, climb, and jump with fewer accidents and more self-confidence. They are beginning to refine their fine motor skills and eye-hand coordination, enabling them to draw simple, recognizable shapes and print a few capital letters. They have almost fully established the preference for right- or left-handedness. They are also beginning to lose their baby teeth and may grow a few inches taller during these years.I decide to attend a local kindergarten class to observe 5-year olds in action. I wanted to verify or debunk my previously mentioned hypotheses regarding the subjects drawn by children and if they still built and took apart items.
