Press release date: January 18, 2013

W. CONSHOHOCKEN, Pa., —A seminar on Temporal Methods will be held April 17, 2013, at the JW Marriott Indianapolis in Indianapolis, Ind. Sponsored by ASTM International Committee E18 on Sensory Evaluation, the seminar will be held in conjunction with the April standards development meetings of the committee.

Time is an important factor in the sensory experience. The onset, duration and sequence of sensations evoked by human sensory interaction with products are key properties in product performance and differentiation. To be able to understand these temporal properties, we must first be able to measure them. At this time, ASTM has only one document relating to temporal measures, ASTM E1909, Standard Guide for Time-Intensity Evaluation of Sensory Attributes. A number of newer methods have been developed and are being used by sensory researchers around the world. In the interest of learning more about these methods and considering their inclusion in the ASTM publications, this seminar will focus on three of those methods and provide participants with a "hands-on" experience with real products and real data collection.

An overview will present the problem: understand if/how the eating experience of a snack bar has been changed by reducing sugar in the formula. The three methods being applied are: 1) progressive profiling; 2) TDS (Temporal Dominance of Sensations); and 3) TOS (Temporal Order of Sensations).

Participants will break into three groups, with each group being led by an experienced practitioner. Data will be collected on the test products live on iPads for later analysis. Everyone will have an opportunity to rotate through and experience all three methods. The final part of the seminar will be devoted to analysis, interpretation and evaluation of the strengths, weaknesses and challenges of these temporal methods. Participants will be able to determine the ease of use by panelists, the clarity of results, the skills required for the analyst and finally the potential value to their business.

Online registration will open approximately six weeks before the seminar. Visit for additional information.
