A growing number of child cognition researchers are using an object-manipulation,sequential-touching paradigm to explore young children's conceptual abilities. Within this paradigm, it is essential to distinguish children's intracategory touching sequences from those expected by chance. The sequential touching approach is congruent with a permutation testing model of statistical inference and is best modeled by sampled permutations as derived from Monte Carlo procedures. In this article, we introduce a computer program for generating Monte Carlo sequential-touching simulations. TouchStat permits users to determine their own specifications to simulate sequential touching to category exemplars across a wide range of task parameters. Weals present Monte Carlo chance probabilities for the standard two-category, four-exemplar task, with sequences up to 30 touches long. Finally, we consider broader applications of the TouchStat program.
