This article is an assessment of a variety of techniques used by researchers
in the fields of geography, psychology, urban planning, and cognitive science to collect
and analyze data on how people with visual impairment or blindness learn,
understand, and think about geographic space. The authors concluded that these techniques
and their results need to be used cautiously. They also made recommendations
for increasing the validity of future studies, including the use of multiple, mutually
supportive tests; larger sample sizes, and movement from the laboratory to real-world
environments
