Descriptive Analysis and Panel Training
In this one-and-a-half-day short course, you will learn new product profiling techniques through an in-depth exploration of descriptive panel methodologies. Specifically, you will connect a substantial body of research from the fields of cognitive psychology and cognitive neuroscience to the field of descriptive analysis and panel training. The topics covered follow. For more details, please see the course brochure and do not hesitate to contact us with any questions. To register, please call 804 675 2980 or use our on-line registration form. Enrollment is limited.
