Abstract
Previous investigations have produced mixed results regarding the relationship between infant temperament and autonomic physiology. The present study assessed whether temperament, as measured by Negative Affect (NA) scores on the Infant Behavior Questionnaire (IBQ-R), was predictive of changes in heart rate throughout an arm restraint task in typically-developing infants (n=24; 10-13 months). Maternal responses to the IBQ-R were collected prior to a developmental assessment (NA=3.47+0.9; M+SD). Infants wore EKG monitors throughout the assessment. We hypothesized that (1) higher NA scores would be associated with a steeper rise in heart rate at the onset of arm restraint and (2) higher NA scores would be associated with a more gradual decline in heart rate during recovery. At this point, heart rate data processing is still ongoing. Analysis of isolated segments of heart rate data will permit us to clarify the relationship between temperament and autonomic physiology in typically-developing infants. This will allow for stronger cross-syndromic comparisons in other areas of developmental research and inform the development of more individualized interventions and treatments.
