The Two-Point Threshold: Not a Measure of Tactile Spatial Resolution 
Current Directions in Psychological Science February 2000 9: 29-32, doi:10.1111/1467-8721.00054

• Is the two-point threshold a valid measurement of spatial resolution? Why or why not?
• What is the difference between objective and subjective measures, in terms of determining the two-point threshold? Is one better than the other?
• Why are gap detection and grating orientation better measures of spatial resolution than the two-point threshold?

Differences in Our Sensory Worlds: Invalid Comparisons With Labeled Scales 
Current Directions in Psychological Science June 2005 14: 122-125, doi:10.1111/j.0963-7214.2005.00346.x

• What are the pitfalls of relative measurement? Are there any advantages to relative measurement?
• What are some examples of how using standards for group comparisons can help the objective measurement of perceptions? Can group comparisons help in measuring the perceptions of all senses?
• How does the gLMS help us understand individual differences in sensation and perception?
• How do invalid comparisons affect our understanding of perception? How can we mitigate the effects of invalid comparisons?
