comment How many users should be tested with
Discussions about sample size in a usability test address two issues: reliability and identifying most major problems. Take a look at the results of Comparative Usability Evaluation project. While sample size influences both factors it is not the only nor the major influence on these factors.

comment Cognitive strain by reading data in tables?
There is plenty of research on the effect of the difficulty of acquiring information on decision making. A simple summary is 'If the user can make a decision without the information and the benefit of acquiring additional information is outweighed by the difficulty of acquiring the information then the user will make the decision without acquiring additional information.' In the situation you describe, a table that is difficult to read may be ignored unless it is the only source of information on which to base a decision.

revised Truncated string usability
Changed the title because 'catenated' is not an accurate description of the problem being discussed. Reworded the next to last sentence to remove 'ubiquitous' because that is the wrong word for the author's purpose.

comment Original design choice of back and forward directions?
Here is evidence to support the claim that arrows point in the direction of tape movement. It is from 1954.

comment Original design choice of back and forward directions?
While reading an answer to this question, I saw the reference to Olsson. Is there any evidence that Olsson designed these controls? I've found nothing to support it.

comment What is the origin of the eject symbol?
Agree the symbol suggests movement. In the context of a cassette player, the horizontal line is the cassette and the arrow suggests movement of the cassette up, i.e., out of the play loop and into the hands of the operator.

comment What is the origin of the eject symbol?
In 1965, the line was above the triangle. See the left-most button on the Grundig C100

comment When to ask a user to take an action multiple times vs. batching it?
Time to execute the task may affect the decision to execute individually or in batch too. You can use a tool like CogTool to estimate task completion time for multiple actions and for batch execution.

comment When to ask a user to take an action multiple times vs. batching it?
This comment does not consider the 'follow' feature mentioned in the question. Instead, it deals with batch execution of a feature that (1) may take a long time to complete, and (2) may not complete succesfully. In that situation, you have to know: (1) whether unsuccessful completion of the action on one object in the list affects completion of the action against other objects in the list, (2) how to present problems encountered during batch execution, and (3) how the user will troubleshoot those problems.

comment Can we Quantify Cognitive Load?
Cognitive load is one aspect of workload - a topic studied extensively by the human factors community. See this TOC and paper for examples for measures of primary or secondary task performance, subjective assessment, and physiological measures. See this example which is available to anybody with an eye tracker - and lots of time.

comment why are the names on sports jerseys in all caps
Tinker's research proposes one model of reading. It is not the only model nor is it the most recent research on the topic. For example, see this paper which argues for greater readability of upper case type.
