THIS MANUAL DESCRIBES MEASURES USED IN "THE COGNITIVE ENVIRONMENTS OF URBAN PRE-SCHOOL CHILDREN" PROJECT AT THE UNIVERSITY OF CHICAGO. THE SAMPLE FOR THE STUDY CONSISTED OF 163 NEGRO MOTHER-CHILD PAIRS SELECTED FROM 3 SOCIOECONOMIC CLASSES BASED ON THE FATHER'S OCCUPATION AND THE PARENTS' EDUCATION. A FOURTH GROUP INCLUDED FATHER-ABSENT FAMILIES. THE MOTHERS WERE INTERVIEWED AT HOME AND THE MOTHERS AND CHILDREN WERE TESTED AT THE UNIVERSITY OF CHICAGO WHEN THE CHILDREN WERE 4 YEARS OLD. FOLLOW-UP DATA WERE OBTAINED WHEN THE CHILDREN WERE 6 AND AGAIN WHEN THEY WERE 7. THE INFORMATION OBTAINED IN THIS PORTION OF THE HOME INTERVIEW WAS USED TO ASSESS THE DEGREE TO WHICH OBJECTS, EXPERIENCES, AND ATTITUDES IN THE HOME AID THE CHILD'S READINESS FOR SCHOOL. THE DATA WERE OBTAINED FROM THE MOTHER'S RESPONSES TO AN EXTENSIVE SERIES OF QUESTIONS SUPPLEMENTED BY THE INTERVIEWER'S OBSERVATIONS. THE RATING, ON A 5-POINT SCALE, WAS MADE FROM AN ASSESSMENT OF THE AVAILABILITY AND UTILIZATION OF THE RESOURCES WHICH WERE CLASSIFIED INTO 9 PATTERNS. INTERPRETATIONS OF THE RATINGS FOR EACH PATTERN ARE GIVEN. PRINCIPAL COMPONENT FACTOR ANALYSIS SHOWED THAT ALL 9 SCALES LOADED HEAVILY ON THE FIRST UNROTATED FACTOR. THE SCORE ON THIS FACTOR WAS USED AS THE BASIC HOME RESOURCES MEASURE. THIS IS A PART OF THE HOME INTERVIEW DESCRIBED IN PS 000 475 AND IS ONE OF THE SAMPLE SOURCES FOR THE LANGUAGE-STYLE ANALYSIS DESCRIBED IN PS 000 492. (DR)
