Area of Science:

  • Cognitive Psychology
  • Developmental Psychology
  • Infant Cognition

Background:

  • Early research suggested infants possess numerical competence.
  • Starkey, Spelke, and Gelman (1990) reported infants could match auditory and visual numerosities.

Purpose of the Study:

  • To re-examine Starkey et al.'s (1990) findings on infant numerical competence.
  • To investigate whether infants can perform cross-modal numerical representations.

Main Methods:

  • Experiment 1: Controlled auditory sequence duration, varying number; measured infant looking time.
  • Experiment 2: Varied auditory sequence rate and duration randomly within infants; measured looking time.

Main Results:

  • Experiment 1: Infants preferred visual displays NOT numerically equivalent to auditory sets.
  • Experiment 2: No significant preference shown when auditory parameters were randomized.

Conclusions:

  • Results challenge claims of cross-modal numerical representation and one-to-one correspondence in infants.
  • Methodological factors, like auditory sequence duration, may influence infant numerical processing.
