Administered five Piagetian tests to 180 adolescents for comparison to similar samples from 1967 and 1972. Found that today's adolescents exhibited higher levels of cognitive development than did previous cohorts. Gain varied across tasks, being very large for combinatory thought but mixed for conservation. This acceleration of cognitive…

This paper discusses the utility of a general systems theory paradigm for psychology. The paradigm can be used for conceptualizing such complex phenomena as change over time in living systems, person-society interactions, and the epistemology of multiply determined changes. Consideration is also given to applications of the approach to…

Investigated was the relation between student ability to translate sentences into equations, equations into sentences, and student performance in formal operational reasoning, proportional reasoning, and introductory-level chemistry. Results indicate that students who lack formal operational skills may experience problems in the translation of…

This article reviews Piagetian theory on formal operational thought, the relationship of psychometric intelligence and formal operational thought, the development of formal operational thought in gifted children, problems encountered with Piagetian theory and attempts to modify it, and implications of the post-Piagetian perspective for education…

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Studied children's transitive inference where representation of premises provided contradictory information depending on position of two elements in a A, B, C series. Eight-year olds did significantly better on the more complex problems than did six-year olds, suggesting the presence of a developmental sequence of algorithms that enable children…

Assessed was the level of thinking of 140 students who had been placed in developmental algebra as entering college freshmen. Scores on the Group Assessment of Logical Thinking, Scholastic Aptitude Tests, college placement tests; high school grade point average, and developmental algebra final grade were analyzed. Group characteristics are…

Examines the relationship between adolescent egocentrism and postformal thinking in 163 college undergraduates. Uses the Imaginary Audience Scale and the Social Paradigm Belief Inventory to evaluate participants. Results indicate that females have higher levels of adolescent egocentrism than do males.

Previous investigations on Piagetian cognitive levels among college students both within and across academic disciplines have not addressed the issue of possible differences in cognitive levels between traditional undergraduates and older returning students. Piagetian cognitive levels were studied among traditional- and nontraditional-age college…

This study examines the developmental status of young mothers' social and logical-physical reasoning in relation to the characteristics of their interactions with their infants. A total of 36 mothers 15 to 21 years of age and their 4-month-old infants were videotaped in their homes during play, infant teaching, and bathing. Selman's "concepts…

A complete equal opportunity program provides an intervention strategy based upon students' diagnosed deficiencies in academic preparation and cognitive development. This study considers formal or abstract operational capability as measured by attainment of Piagetian tasks by special-admission students in a large midwestern university. (LHW)

Examined high school students' scores on test of formal thinking and those on test of reading. Students' success on both tests was disappointingly low. Lack of motivation appeared to be major problem. Correlations between scores on two tests were relatively low, although there was suggestive similarity between distribution of scores for formal…

Twenty-nine children with learning disabilities (LD) in grades 2 and 4 through 7 were compared with children without LD for their development of proportional structures of thought. Significantly fewer children with LD had constructed second-order logical structures necessary to act on problems using multiplicative and preproportional reasoning.…

Misconceptions, shown to be prevalent in students even at the college level, may affect the cognitive process of making predictions in biology. The purpose of this study was to: (1) identify students' misconceptions about important biological concepts; (2) identify students' cognitive behaviors associated with making predictions about these…

As an introduction to exploring the possibilities of an inservice plan to facilitate teacher cognitive development, the theories of educational philosophers and developmental psychologists are cited in arriving at a broad definition of the cognitive development of adults. From these theories it is surmised that teachers do operate at different…
