The study of 281 adolescents found no significant differences in creativity subvariables between the developmental stages of concrete and formal operations. Significant relationships were found between age and creativity. Figural flexibility, originality, and elaboration decreased as age increased from 13 to 16 years. (Author/JDD)

The goal of this research synthesis is to evaluate the validity of the claim that there are fundamental limitations on the ability of adolescents to engage in critical thinking. Critical thinking is defined as an analytic, focused cognitive activity aimed at understanding phenomena at a root rather than a superficial level; a type of thinking…

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…

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…

Administered the Adolescent Egocentrism Scale (AES) to middle and high school students (N=129). Found partial support for Inhelder and Piaget's and Elkind's views that adolescent egocentrism is a function of beginning formal operations. Discusses the difficulty of assessing the true thoughts/feelings of persons who are worried how they will appear…

To evaluate the part that nascent skeptical doubt plays in shaping adolescent social-cognitive development, 61 high school students clearly classified as in concrete or formal operational stages of cognitive development completed a measure of epistemic stances. A relationship was found between cognitive and epistemic development. (SLD)

Considers the period of adolescence and describes how cognitive-developmental concerns might apply to the understanding of adolescent problems in interpersonal and affective adaptation. Also investigates ways in which intervention practices with adolescents might be placed within a cognitive-developmental context. (PCB)

This paper reviews some literature on the emergence of formal reasoning and reports a study of reasoning performance of 213 middle grade students in relationship to grade level and chronological age. While a number of large-scale studies have indicated that formal reasoning emerges in a regular progression across age ranges and grade levels, few…

Investigated the relationship between the development of formal operations and the formation of ego identity in adolescence. Obtained significant positive correlations between combinatorial ability and degree of identity, suggesting that high identity may facilitate the application of combinatorial operations. Found some gender differences in task…

This book describes the Reflective Judgment Model (RJM) and provides a comprehensive review of the research on it and the Reflective Judgment Interview (RJI). Chapter 1 defines reflective judgment as an often neglected aspect of critical thinking. Chapter 2 discusses stage-related assumptions that underlie RJM and relates RJM to current work in…

A common concern raised by teachers from secondary schools and junior colleges in Singapore is the apparent inability or reluctance of adolescents to think critically and originally. Adolescent thought processes are probably shaped by the change in intellectual pace and quality between the primary and secondary school curriculum. This study of…
