Abstract:
Abstract: It is commonly believed that certain methods of
cognitive assessment share some degree of relationship. For
example, one would predict that the Stroop paradigm and Simon
paradigm, both believed to assess the influence of irrelevant
information on processing time, would have a high degree of
correlation. The present study investigated the extent to which
this is true. The standard paradigms of Stroop, Simon, choice
reaction time, and inspection time were used. Fifty subjects
completed two sessions of each test. On one day subjects completed
the tests Stroop, Simon, choice reaction time, and inspection time
in a random order. Two days later subjects completed the same test.
The intra-test correlations (e.g., Stroop versus Stroop) and
inter-test correlations (e.g., Stroop versus Simon) were assessed.
The data showed that the intra-test correlations were high, as
predicted, but the inter-test correlations were surprisingly low.
These data are interpreted to suggest that although face validity
suggests measures of cognitive assessment are related, they may not
be.
