Self-concept and self-esteem reexamined

Three “self” constructs are differentiated: the “self,” that is, the “real” self; the “self-concept,” which is the information or cognitions an individual has about his “self;” and “self-esteem,” which is the judgment and feelings about the “self.” An individual's self-concept can be characterized by its realism or unrealism, its completeness or incompleteness, or by the complexity of the concepts used to describe the self. Self-esteem, but not self-concept, can be described as being positive or negative. Developmental considerations and implications are discussed.     

Pygmalion in the classroom

In 1965 the authors conducted an experiment in a public elementary school, telling teachers that certain children could be expected to be “growth spurters,” based on the students' results on the Harvard Test of Inflected Acquisition. In point of fact, the test was nonexistent and those children designated as “spurters” were chosen at random. What Rosenthal and Jacobson hoped to determine by this experiment was the degree (if any) to which changes in teacher expectation produce changes in student achievement. Robert Rosenthal is professor of social psychology at Harvard University. Lenore Jacobson is an elementary school principal in the South San Francisco Unified School District.
