This final report of a study which developed a working corpus of spoken and written Portuguese from which syntactical studies could be conducted includes computer-processed data on which the findings and analysis are based. A data base, obtained by taping some 487 conversations between Brazil and the United States, serves as the corpus from which…

Current transformational linguistic theory holds that there are two levels of sentence structure, derived constituent or surface structure and underlying or deep structure. Both have been proposed as the memory representation of sentences, but recent evidence suggests that the latter is the more likely. However, two recent studies have directly…

This report contains a description of the principal results and conclusions concerning the impact of educational performance contracting on student achievement in two school districts that subcontracted with its local educational association to test the use of incentives in regular classrooms.

MODELS OF A SCHOOL COUNSELOR'S COGNITIVE BEHAVIOR IN THE APPRAISAL OF STUDENT INFORMATION AND OF HIS OVERT VERBAL RESPONSES IN THE "EDUCATIONAL PLANNING INTERVIEW" WERE MADE WITH COMPUTER PROGRAMS AND COMPUTER-CONTROLLED EQUIPMENT. THE VERBALIZATIONS OF THE COUNSELOR WHILE REVIEWING THE RECORDS OF 20 NINTH-GRADE STUDENTS PRIOR TO…

A MANUAL WAS PRODUCED CONTAINING LABORATORY PROCEDURES FOR A ONE-SEMESTER COURSE IN ELEMENTARY QUANTITATIVE CHEMISTRY ON A COLLEGE FRESHMAN LEVEL. MATERIALS AND TOPICS WERE EXAMINED AND CHOSEN AS TO DESIRABILITY, PRACTICALITY, AND EDUCATIONAL VALUE. OPTIONAL EXPERIMENTS WERE ALSO INCLUDED. THE LABORATORY PROCEDURES WERE TESTED ON SOPHOMORES AND ON…

Studies of social comparison choice have utilized a paradigm which fails to distinguish comparison motives from more general information search motives. In the present study subjects were either exposed to the standard social comparison manipulation or asked to determine the distribution of a set of unknown random variables arranged in rank order.…

The relative effectiveness of alternative reward structures in strengthening group performance on a cooperative math task was investigated by operationalizing four reward structure treatments--one non-contingent pay treatment and three differential pay allocation treatments including two levels of inter-group competition and a group piece-rate pay…

This paper reports on an experiment examining sex differences in the types and meanings of emotional responses to a particular projective test: May's deprivation/enhancement measure (D/E), which is seen as an index of gender identity. The measure consistently differentiates males and females, which May felt reflected both physiological and…

The primary purpose of this study was to examine the attitudes of non-disabled persons toward physically disabled persons.
