The human’s purpose is to reach to his perfection. He is also trying to provide easy and better life for himself and others. For reaching to his perfection and overcomehis inferiorities, he must reach to his goals and satisfies his needs which are basic stimulus for human’s behavior. Roe (1957) believes that basic stimulus for having certain behavior is human’s need. O,Hara and Tiede man (1963) believes to make a decision is important and unseparable factor for continuation of life. Coopersmith (1969) says self-observation is determinative of behavior. Ansbacher (1967) believe’s that for reaching to a certain goal, one needs to have a certain method. This method can be named his life style. Life style which is a mixed interaction between self-observation, needs and decision making has important effection in determining the way of activity.
The purpose of this research is; (1) to determine how much effects (A) self- observation (B) decision and (C) needs have on choosing agricultural field as a major and (2) to determine correlation between each of this factors with environmental factors such as teacher, friends and parients.
The study has been done in the year 1988, the population of the study has been 259 of first year students of the Tehran University. A question flair has been used to gather information. Mean and percentage was calculated. Results show 83.5% for self—observation. 70.20% for decion making and 63.80% for self-satisfaction effecting students to select agriculture as a major of study.
The correlation coeficient was determined between two groups of students registering in continued period of study program, and discontinued periods of study program, showing only for self-satisfaction and self-observation. This study indicates that they are no correlations between environmental factors and decision, self—observation and satisfaction, in selecting agriculture as a major.
