Abstract:Examining specific cognitive abilities as conceptual surrogates of overall cognitive development is a common procedure in psychology. The present study focuses on assessing developmentally disabled children’s level of understanding of object permanence and categorization with eye tracking methods. Additionally to developmentally disabled children were participants from the general population assessed in a separate experiment, to act as indicators of assessment tasks’ construct validity. Participants were assessed on three different categorization- and two different object permanence tasks. Participants were hypothesized to look longer or shorter at areas of interest in experimental conditions during a certain timeframe, compared to control conditions. A single case randomization model analyses could not detect a significant influence of condition on gaze duration. Visual analyses of the data yielded some of the hypothesized results. Shortcomings of the study, reasons for the lack of hypothesized results and implications for future research are discussed.
