Evaluation of a 10-minute version of the Attention Network Test.

The widely used Java version of the Attention Network Test (ANT), which can be downloaded from https://www.sacklerinstitute.org/cornell/assays_and_tools/ , takes approximately 20 minutes to complete. A shorter version would be useful in clinical or applied research settings where many tests are administered. We assessed how well a new 10-minute version of the ANT agrees with the 20-minute version. Response time (RT) measures from the shorter version correlated very highly with the corresponding measures from the 20-minute version (Pearson correlations ranging from .88 to .92). Therefore RT measures from the shorter version can safely be used in place of those same measures from the 20-minute version. Correlations for the three network scores (alerting, orienting and conflict efficiency) were not as strong (range = .10 to .53). This is not surprising, given that the network scores are difference scores. Further research is needed to determine whether adequate reliability can be achieved for the network scores without unduly increasing the length of the task.
