CSA Panel Training & Management

Question 1

Which screening test is most commonly used to identify color vision deficiencies in candidates before recruiting them for a sensory panel?

Accepted Answer

Ishihara Color Plates Test

Answer

The Ishihara Color Plates Test is the standard initial screen for red-green color blindness, making it the most common recruitment screen for sensory panels.

Question 2

During panelist screening, a triangle test is used primarily to assess a candidate's ability to:

Accepted Answer

Discriminate between two similar samples

Answer

The triangle test presents three samples (two identical, one different) and measures whether a candidate can reliably identify the odd sample, indicating basic discrimination ability.

Question 3

In sensory panel recruitment, a detection threshold test is conducted primarily to determine:

Accepted Answer

The minimum stimulus concentration a candidate can perceive

Answer

Threshold testing establishes the lowest concentration at which a stimulus can be detected, helping ensure recruits have adequate sensory sensitivity for the target attribute.

Question 4

The 'halo effect' in sensory panel training refers to:

Accepted Answer

The tendency for overall product impression to bias ratings of individual attributes

Answer

The halo effect occurs when a panelist's global impression (positive or negative) bleeds into ratings of specific attributes, reducing their independence and accuracy.

Question 5

The primary purpose of 'anchoring' a rating scale during descriptive panel training is to:

Accepted Answer

Define specific sensory intensities at scale reference points using physical or chemical standards

Answer

Anchoring ties specific points on the scale to real physical or chemical references, so all panelists interpret intensity levels the same way.
