Cognitive mechanisms of serially organized behavior (supplement)  

Ordinal relationships, or the concept of establishing order, rank, or position in a series (e.g., first, second, third), exert a pervasive influence on behavior. Studies in humans and animals have shown that a non-linguistic basis may underlie such serial learning, and the proposed research will advance understanding of the representation of order in humans and monkeys. The studies will use a variety of proven methods for training monkeys to execute lists composed of arbitrary stimuli and stimuli that can be characterized as inherently ordered. In one task, for example, the subjects must learn to generate a representation of an entire sequence and their current position in that sequence as they move from item to item. In another task using transitive inference (inferential reasoning), subjects are rewarded when they choose the correct item from a pair of stimuli to establish an order for the series of items. They are then tested on their ability to infer the correct item from pairs of non-adjacent items. The hypothesis is that the nonverbal representation of an ordinal relationship can be transferred between the ordinal (ordering) tasks tested in these experiments (spatial, numerical, psychophysical, serial, or transitive discrimination tasks). The results may have particular implication for developing nonverbal diagnostic tools for autistic children. Project Status
