Eye-tracking technology may represent a possible solution to overcoming issues related to motor disability in cognitive assessment. In this study we assessed the equivalence between the standard version of the Kaufman Brief Intelligence Test-second edition (KBIT-2) and its eye-controlled version. Forty-three undergraduate volunteers were administered the KBIT-2 twice in a counterbalanced within-subjects design. Overall, scores obtained in the eye-controlled version correlate with those obtained in the standard version. Significant differences were found between raw scores, number of errors and time needed to complete the test in the Vocabulary subtest but not in the Matrices subtest. Further analyses revealed no significant differences in cognitive workload across test modalities. Explanations and implications for further research are discussed.

Abstract

Eye-tracking technology may represent a possible solution to overcoming issues related to motor disability in cognitive assessment. In this study we assessed the equivalence between the standard version of the Kaufman Brief Intelligence Test-second edition (KBIT-2) and its eye-controlled version. Forty-three undergraduate volunteers were administered the KBIT-2 twice in a counterbalanced within-subjects design. Overall, scores obtained in the eye-controlled version correlate with those obtained in the standard version. Significant differences were found between raw scores, number of errors and time needed to complete the test in the Vocabulary subtest but not in the Matrices subtest. Further analyses revealed no significant differences in cognitive workload across test modalities. Explanations and implications for further research are discussed.
