THE "I.Q." AND POTENTIAL.
KIRK, SAMUEL A.
IT IS PROPOSED THAT MENTAL RETARDATION IS NOT NECESSARILY CAUSED BY A GENETIC FACTOR OR BY BRAIN INJURY, BUT MAY BE CAUSED BY THE CULTURAL ENVIRONMENT IN WHICH CHILDREN ARE RAISED. WHEN CHILDREN ARE LEFT IN PSYCHOSOCIALLY DEPRIVED HOMES, THEIR RATE OF DEVELOPMENT WILL TEND TO DECLINE. IF, AT AN EARLY AGE, THEY ARE PLACED IN A SCHOOL FOR A FEW HOURS EACH DAY, THEIR RATE OF DEVELOPMENT WILL TEND TO INCREASE OR AT LEAST TO HOLD CONSTANT. HOME TRAINING AND HOME AND SCHOOL ENVIRONMENTS ARE IMPORTANT FACTORS IN CHILD DEVELOPMENT. WHEN CHILDREN ARE ADMITTED TO SCHOOL, THEY TEND TO WIDEN THEIR HORIZON OF EXPERIENCE AND THEIR INTELLECTUAL DEVELOPMENT ACCELERATES. EVIDENCE IS PRESENTED TO SHOW THE EFFECTS OF SCHOOLING ON INTELLECTUAL DEVELOPMENT. CHILDREN STUDIED WERE FROM STATE INSTITUTIONS, UNDERPRIVILEGED HOMES, OR COMMUNITIES WHERE CHILDREN WERE NOT TRAINED AT THE PRESCHOOL LEVEL. ONE EXPERIMENT INVOLVED A SET OF 5 YEAR OLD TWINS, IDENTIFIED AS THE ALPHA TWINS, ONE LEFT-HANDED AND ONE RIGHT-HANDED. THE LEFT-HANDED CHILD HAD A SLIGHT SPEECH DEFECT AND AN I.Q. OF ABOUT 75. THE RIGHT-HANDED CHILD SEEMED TO BE THE LEADER. HE HAD NO SPEECH DEFECT AND AN I.Q. OF 86. THE LEFT-HANDED CHILD WAS PLACED IN A PRESCHOOL. AT THE AGE OF SIX, BOTH WERE RETESTED. THE LEFT-HANDED TWIN'S I.Q. ROSE TO 86, SHE APPEARED TO BE THE LEADER. HER TWIN EXPERIENCED A DROP IN I.Q. TO 78.
