    Abstract
    Behavioral indices (e.g., infant looking) are predominantly used in studies of infant cognition, but psychophysiological measures have been increasingly integrated into common infant paradigms. The current study reports a result in which behavioral measures and physiological measures were both incorporated in a task designed to study infant number discrimination. Seven-month-old infants were habituated to several sets of stimuli varying in object type, but of a constant numerical value (either 2 or 3 items). Although looking time to each of the test trials revealed no differences, differences in heart-rate defined measures of attention revealed infants’ ability to discriminate number. These findings imply that the inclusion of indices other than behavioral measures should become commonplace in studies of infant cognition.
