Long hours of paid employment during high school have been linked to a variety of problem behaviors, but questions remain about whether and to what extent work intensity makes any causal contribution. This study addresses those questions by focusing on how 12th-grade work intensity is associated with substance use and educational attainment in the…

This study suggests a fifth Piagetian stage and offers empirical evidence in its support. Piaget's traditional fourth stage (formal operations) is operationally defined as the problem-solving stage and the suggested fifth stage as the problem-finding stage. The commonly accepted criteria for a stage model are applied. (JMB)

A matching task was presented to 120 subjects from 6 to 20 years of age to investigate the relative influence of dimensional salience and salience of variability on problem solving. The task included four dimensions: form, color, number, and position. (LLK)

College students were assigned to either dyadic or individual problem-solving conditions and were given a series of formal operational tasks. Dyadic subjects solved more problems during the interaction phase than did individual subjects. Among dyadic subjects, interactions were associated with problem solving and pre-to-posttest gain scores. (BC)

In a sample of 64 students (grades 8 and 11, undergraduate, and graduate), this study assesses evaluation and understanding of moral-stage-prototypic statements equated for level of language. Results support the hierarchical nature of moral stages despite the equating of language level. (Author/RH)
