PROBLEMS RELATED TO SEX DIFFERENCES IN ACHIEVEMENT AMONG ABLE HIGH SCHOOL YOUTH WERE STUDIED--(1) THE LACK OF CORRELATION BETWEEN A MEASURE OF ACHIEVEMENT MOTIVATION AND ACTUAL SCHOOL ACHIEVEMENT AMONG GIRLS, AND (2) THE RELATIVELY DIFFERENT EFFECT OF CERTAIN PARENTAL ATTITUDES ON THE ACHIEVEMENT BEHAVIOR OF BOYS AND GIRLS. THE SUBJECTS USED WERE ABOUT 100 BOYS AND GIRLS IN THE 12TH GRADE (EACH HAD BEEN TESTED ON A NUMBER OF NONINTELLECTUAL VARIABLES 2 YEARS PREVIOUSLY). ALMOST 90 OF THEIR FATHERS WERE ADMINISTERED A PARENTAL ATTITUDES TEST. THE MOTHERS HAD BEEN TESTED PREVIOUSLY DURING A FORMER STUDY USING THE SAME STUDENT SUBJECTS. ALL SUBJECTS WERE ADMINISTERED ACHIEVEMENT AND ATTITUDE TESTS. THE FINDINGS OF THIS STUDY AND THE FORMER STUDY RESULTED IN THE FOLLOWING CONCLUSIONS--(1) ACHIEVEMENT MOTIVATION IN GIRLS IS RELATED TO MOTIVATION TO REACH ADULTHOOD EARLY, RATHER THAN TO MOTIVATION TO ACHIEVE ACADEMICALLY, (2) FOR BOYS, IT IS RELATED TO "COLLEGE GOING" AND ACADEMIC ACHIEVEMENT, AND (3) ACADEMIC ACHIEVEMENT OF BOYS IS AIDED BY HOME SITUATIONS WHICH ARE RELATIVELY DEMOCRATIC, WHEREAS ACADEMIC ACHIEVEMENT OF GIRLS APPEARS TO BE AIDED BY HOMES WHICH ARE MORE STRICT AND DEMANDING. FURTHER RESEARCH WAS RECOMMENDED TO ACHIEVE AN EVEN GREATER UNDERSTANDING IN SUCH AREAS AS ACHIEVEMENT MOTIVATION, VALUES, PARENT ATTITUDES RELATED TO ACHIEVEMENT, AND LEVELS OF ASPIRATIONS IN GIRLS.
