The present research aims to:

1. Acquainting with self-determination for the college students.
2. Acquainting with emotional experience for the college students.
3. Acquainting with achievement striving for the college students.
4. Acquainting with the significance differences in self-determination for the college students according to two variables : gender “males, females” and major “scientific,humanistic”
5. Acquainting with the significant differences in emotional experience for the college students according to two variables :gender “males, females” and major “scientific , humanistic”
6. Acquainting with the significant differences in achievement striving for the college students according to two variables : gender “males, females “ major “scientific , humanistic”
