The ACT theory of the learning of procedures is described. ACT is a computer simulation program that uses a propositional network to represent knowledge of general facts and a set of productions (condition action rules) to represent knowledge of procedures. There are currently four different mechanisms by which ACT can make additions and…

This report describes the principal findings and recommendations of a 2-year Rand research project on machine-aided knowledge acquisition and discusses the transfer of expertise from humans to machines, as well as the functions of planning, debugging, knowledge refinement, and autonomous machine learning. The relative advantages of humans and…

The study compares the performance of 50 fourth grade learning disabled students on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Tests of Cognitive Abilities from the Woodcock-Johnson Psycho-Educational Battery (WJTCA). Results indicated that learning disabled Ss performed more poorly on the Tests of Cognitive Abilities…

Two studies were conducted to (1) analyze the subtest characteristics of the Woodcock-Johnson Psycho-Educational Battery, and (2) apply those results to an analysis of 50 fourth grade learning disabled (LD) students' performance on the Battery. Analyses indicated that the poorer performance of LD students on the Woodcock-Johnson Tests of Cognitive…

Eighty-one fourth grade students were administered tests, tasks, and observations to investigate the relationship between IQ, rates of learning, scores on standardized achievement tests, and results of classroom observation. There was a substantial relationship between IQ, standardized tests, and rates of learning, but not classroom observation.…

The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

A study involving 59 undergraduate speech communication students investigated relationships between intelligence, understanding of editorial satire, and appreciation of satire. The students were asked to read three satirical essays and then to pick one of five statements that best described the thesis as intended by the author. Then each satire…

THE OBJECTIVE OF THIS STUDY WAS TO MINIMIZE THE VARIABILITY IN LEGAL AND EDUCATIONAL CLASSIFICATION OF THE MENTALLY RETARDED. A SYSTEMATIC REVIEW WAS MADE OF THE SEMANTIC VARIATIONS IN THE DEFINITION OF THE MENTALLY RETARDED IN TERMS OF FUNCTIONAL ADEQUACY FOR EDUCATION, TRAINING, OR CUSTODIAL CARE. THE METHOD INVOLVED THE REVIEW OF STATUTES AND…

LOW BIRTH WEIGHT CHILDREN WERE STUDIED LONGITUDINALLY TO DETERMINE WHETHER--(1) THE RELATIVE INTELLECTUAL IMPAIRMENT OF PREMATURE CHILDREN IS STATIC OR CHANGES WITH TIME, (2) A LOW BIRTH WEIGHT CHILD NOT NOTED TO BE IN NEUROLOGICAL DISTRESS COULD HAVE A POOR PROGNOSIS, AND (3) SPECIAL EDUCATIONAL AND EMOTIONAL PROBLEMS COULD ARISE AS A CONSEQUENCE…

THIS IS THE REPORT OF A PILOT INVESTIGATION DESIGNED (1) TO STUDY THE ABILITY OF CHILDREN IN REGULAR CLASSROOM SETTINGS TO ORGANIZE INFORMATION THEY POSSESS IN WAYS SUGGESTED BY TWO DIMENSIONS OF THE GUILFORD STRUCTURE OF INTELLECT MODEL, AND (2) TO EVALUATE THE FEASIBILITY AND DESIRABILITY OF MAKING PARTICIPATION IN THE STUDY, IN DATA COLLECTION…

THE COMPARATIVE VALIDITY OF THE LEE-CLARK READING READINESS TEST AND THE CALIFORNIA TEST OF MENTAL MATURITY (CTMM) FOR PREDICTING GRADE 1 READING SUCCESS WAS STUDIED. ALL ENTERING FIRST-GRADE PUPILS IN TWO ELEMENTARY SCHOOLS IN A LOW-MIDDLE-CLASS COMMUNITY WERE ADMINISTERED BOTH TESTS DURING THE FIRST 3 WEEKS OF SCHOOL. PERFORMANCES ON THESE TESTS…

The study compared the behavior of 61 preschool autistic children with that of 35 retarded children matched for mental age and 30 normal children matched for chronological age. Ss were rated on a 67 item Behavior Observation Scale during three free play sessions. Among findings were that six behaviors (grimace/gesticulation, echolalic speech,…

In a prospective longitudinal study, 1244 children who had received three neurological examinations in their first year of life were administered measures of cognitive development and academic achievement through age 12. Twenty-two Ss identified as neurologically suspect or abnormal on more than one of the infant examinations consistently…

The Soviet position on vocabulary and the relationships among intelligence, language, and culture holds that thoughts and words have different developmental roots and that there are more differences than likenesses between them. In this United States study, 105 students grouped by their having parents in three different employment categories were…

This paper begins with a description of four generations of research in machine translation: the original efforts of 1957 to 1965 and three types of surviving and sometimes competing present projects. The three types of present projects include those relying on "brute force" methods involving larger and faster computers; those based on a…
