revised How to set norms cut-off for 3 point Likert scale?
Changed the lower case l in likert to upper case because Likert is a proper noun.

comment How to set norms cut-off for 3 point Likert scale?
A Likert scale has many uses. It's difficult to answer the question without more detail regarding the use of the scale and the purpose of the cut-off score.

comment What is the term for designing an element such that it visually reflects the spatial design of the object in real life?
Part II - Please use caution when using terms like 'natural' and 'obvious' when describing control-display relationships. Many 'natural' layouts are 'natural' for one group of users but not for other groups. Look for research on 'population stereotype', 'control display relationship/layout', and 'stimulus response compatibility'.

comment What is the term for designing an element such that it visually reflects the spatial design of the object in real life?
Part I - It is unlikely 'natural mapping' is the correct term. Here are 4 research papers on this topic. None of them use this term: 1, 2, 3, 4, Unfortunately, I have not found another term that answers your question.

comment What are the primary reasons that customers don't purchase AB Testing services?
There are many inexpensive A/B testing services available. Integrating them with a production web site is easy. Setting up, running, and analyzing a test is easy. It's possible your customers do not need your UX consulting agency to run an A/B test.

comment Audio warning patterns
There are many research studies and guidelines on auditory display design. For example, this research investigates the relationship between the frequency of a beeps and perceived urgency. Search for 'auditory display', tones, and 'human factors'.

comment Color Emotion Naming Convention Standard?
Part I - There is (almost) a century of research on this topic. As Aadam points out, there are cultural differences in the meaning of color. However, 'meaning' and 'emotion' are not the same thing. I'll attempt to answer the question as it is posed where mood is related to emotion. First, the relationship between emotion and color depends on your model of emotion. Second, 'color' can be broken down into hue, chroma, and brightness. The rest of my comment references research into this topic. Whether the UI framework color names are based on this research is unknown.

comment Why are messages on the road printed in reverse?
Part II - Putting the words in traditional order would mean one of two things: (1) assume constant letter size - the driver will be past the words at the end of the message by the time the driver needs to read the message, or (2) assume letter size variable letter size - the words at the beginning of the message would have to be much larger than the words at the end of the message because the words at the beginning of the message have to be readable sooner and from a larger distance than the words at the end of the message.

comment Why are messages on the road printed in reverse?
Part I - The minimum recommended preview time is 3s. See page 20-2. Guidelines for the minimum visual angle of horizontal signing are described here on page 3.. These two values and the average travel speed of a vehicle on the road where the sign appears gives you the reason for the reverse ordering of words in a message.

comment Do signs printed on the road offer a significant advantage for the user over signs on a post?
Part II - Look at the values in the % Change column in the section titled 'Signs'. The negative values in this section indicate greater effectiveness than the pavement marking signs referenced in the other section. This means the pavement marking signs were more effective in getting drivers to obey the posted speed limit but enhanced road-side signs were more effective than pavement markings.
