The role of negative priming in preschoolers' flexible rule use on the dimensional change card sort task

Four experiments examined the development of negative priming (NP) in 3-5-year-old children using as a measure of children's executive function (EF) the dimensional change card sort (DCCS) task. In the NP version of the DCCS, the values of the sorting dimension that is relevant during the preswitch phase are removed during the postswitch phase. The experiments showed that the NP effect observed in the DCCS decreased during the preschool years, and they clarified the circumstances in which NP occurs. Taken together, the findings suggest that the development of EF in early childhood consists in part in disinhibiting attention to information that has previously been suppressed.     

Preparing Performance Technologists: The Role of Universities Originally published in 1995, PIQ 8.4

It has been several years since the concept of performance technology was introduced in the literature. This article describes how the Instructional Systems program at Florida State University has responded to the changes that are required to expand its orientation from instructional technology to performance technology. Gradual changes in several existing courses and the implementation of two new courses in performance systems analysis and electronic performance support systems are described. In the new courses, students interact with clients to determine needs, examine processes, design solutions, and determine returns on investments. Consideration is also given in the article to ways other universities might respond to the changes in the direction of the field.     

Quality in Training Organizations

This article examines the implications of applying quality principles to the systematic design of training, considering 1) the definition and characteristics of a quality training system, 2) the requirements for establishing such a system, 3) how TQM might impact present procedures and, 4) some anticipated reactions of experienced designers to the idea of a quality training system.
