Temperament

A childs style, or how they experience and respond to the world

  • Reactivity, novelty, postive/negative expressiveness

A child’s ‘general’ behavior, not their specific reactions

3 categories of babies:

  • (40%) Easy - happy, adaptable, regular
  • (10%) Difficult - unhappy, irregular, negative responses to novelty
  • (15%) slow-to-warm-up - unhappy, not upset by unfamiliar situations
  • (35%) unclassified - mix of traits
    These results were based on a longitudinal interview with the parents

Judging temperament is a particularly difficult, hard to observe child in a ‘normal’ state in lab


In lab temperament observations:

  • Measure how infants respond to general situations:
    • behaviors
    • physiological responses (heart rate, frontal brain activity (right and left frontal lobes))
      • objective measurements, not biased like parental report
