This compilation of three papers investigates theoretical and practical facets of career development, focusing on cognitive theory and decision-making theory and their roles in the formation of computerized career development systems. In the first paper ("Cognitive-Behavioral Theory and Its Application to Career Development"), Gerald Stone describes three cognitive-behavioral theories (social learning, cognitive restructuring, and cognitive development). He highlights the importance of individual constructs in explaining human behavior and explores applications of the theories to career issues. The second paper ("Career Decision Making"), by David Jepsen, reviews career decision-making models, focusing on the processes that people use to organize information about themselves and their surroundings in order to make vocational decisions. He also describes a number of decision-making aids, such as decision trees and simulations, and concludes by summarizing implications of the models for theory and research. Roger Myers, in the third paper ("Computerized Approaches to Facilitating Career Development"), depicts the state of the art of computerized approaches to career development. Distinguishing between computer-based information and guidance systems, he shows how the latter use both cognitive theory and decision-making theory to contribute to the process of career choice. The compilation concludes with an extensive list of references. (SK)
