Chuo University - Korakuen campus
Tokyo, Japan

September 13-15, 2017

Tools and Applications of Sensory and Consumer Science

20% discount will be applied to each additional registration made at the same time, from the same company. Academic discount available upon request.

*If you qualify for an academic discount or need to make multiple registrations from the same company, please contact Sue Longest by email before registering to receive special discount payment information.

Fee includes a manual with printed versions of the presentation slides, lunches and refreshments each day. You will also receive access to a free 3-month trial version of IFPrograms software and our current books, Tools and Applications of Sensory and Consumer Science and Thurstonian Models: Categorical Decision Making in the Presence of Noise.

This course has been developed for personnel involved in sensory evaluation, market research, product development, quality assurance, and general management within consumer product companies. The content is easily accessible and will provide lasting benefits for attendees with both introductory and advanced level knowledge in sensory evaluation and market research.

Dr. Benoît Rousseau of The Institute for Perception will teach this course. On Friday, Dr. Chinatsu Kasamatsu of Ajinomoto will share an application of Landscape Segmentation Analysis® to strawberry jam products.

Language of instruction

The course will be taught in English. Clarification in Japanese will be provided as requested by participants.


A special room rate is available at the Hotel Niwa Tokyo, conveniently located close to the Chuo University campus.

Tools and Applications of Sensory and Consumer Science

By attending this three-day course you will:

  • Understand why different sensory methodologies can results in different conclusions
  • Explore the tetrad test as a powerful alternative to the triangle test
  • Learn to assess and manage risks in product testing decisions
  • Develop internal standards taking into account consumer expressed preferences
  • Connect results of internal panel testing to consumer response
  • Establish your experiment’s optimal sample size, including potential replications
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 online registration form.

Wednesday, September 13 (9am - 5pm)

Corporate Scenario - Day 1: The scenario begins with a proposed ingredient change. We follow the product study process starting with inconsistent difference test results and then continue as the tetrad test and replicated testing are used.


  • Difference and equivalency testing
  • m-AFC, triangle, duo-trio, same-different, and tetrads: Why they provide different conclusions
  • The Thurstonian framework underlying all sensory evaluation methods - the science of sensory
  • Calculating a measure of sensory difference, d', from discrimination tests and how to inter-relate methodologies
  • Proportion of discriminators in the population
  • The tetrad test: Why it requires 1/3 the data than the triangle test
  • How to correctly analyze data from replicated tests

Thursday, September 14 (9am - 5pm)

Corporate Scenario - Day 2: The scenario continues as management requests a decision-risk analysis of the entire product testing system. See how the team links external data to consumer data to establish consumer relevance.


  • The 5 cornerstones of product testing: α, power, sample size, size of the difference and protocol
  • How to explain a consumer preference without a demonstrated sensory difference
  • Finding the optimal sample size for tests
  • Establishing an internal sensory program based on a consumer relevant action standard
  • Measuring the effect of training
  • Relating trained panel and consumer sensitivities

Friday, September 15 (9am - 5pm)

Corporate Scenario - Day 3: Issues of sensory segmentation and portfolio optimization arise and the team is challenged to understand and communicate the benefits of alternative methodologies.


  • Introduction to the sensory and Drivers of Liking® spaces
  • Factor analysis and external preference mapping: Strengths and weaknesses
  • Unfolding: Introduction to Landscape Segmentation Analysis® (LSA)
  • How to identify Drivers of Liking®
  • LSA vs. internal preference mapping: The issue of satiety
  • Portfolio optimization, product optimal profile predictions
  • Segmentation and demographics
  • Application of LSA to strawberry jam products - Presented by Dr. Chinatsu Kasamatsu, Ajinomoto Co., Inc.
