Study Notes
Screening Process
- Determines individuals satisfy minimum criteria for selection
- Criteria dependent on test type, may be as simple as personal availability
- More complex selection criteria = more difficult, time-consuming, and expensive to find participants
Panel Control
- Types of panels:
- Semi-trained sensory panel: participates in simple sensory tests, minimal screening required
- Consumers (Naive assessors): selected for one-off or frequent affective tests, screening involves simple questions
- Trained panel: individuals exhibit suitable personality and attitude traits, good health, and minimum criteria for sensory acuity
Trained Panel Requirements
- Personality traits:
- Ability to work as a team
- Wide range of preferences
- Positive but not overbearing
- Good listener and communicator
- Commitment and flexibility
- Health: good general health, documented physiological or health restrictions
- Sensory acuity:
- Normal sensory acuity for detecting, discriminating, recognizing, and describing stimuli
- Ability to detect visual, odor, tactile, and taste stimuli at typical concentrations/intensities
Training for Descriptive Tests
- Includes training on product-specific attributes
- Mini profile: a useful training tool for assessors to become familiar and confident with the test protocol
Training for Affective Tests
- Clear description of the test method required
- No assessor training needed for face-to-face interviews, guidance may be needed for computer-based questionnaires
Motivation
- Improves/maintains the quality of assessors' data
- Methods to improve motivation:
- Financial incentives
- Group activities, e.g., related to work, to keep assessors focused and invested in the task
