title: A comparison of video versus conventional visual reinforcement in 7- to 16-month-old infants.
abstract: OBJECTIVE
  To compare response patterns to video visual reinforcement audiometry (VVRA) and conventional visual reinforcement audiometry (CVRA) in infants 7-16 months of age.
  
  
  METHODS
  Fourteen normal-hearing infants aged 7-16 months (8 male, 6 female) participated. A repeated measures design was used. Each infant was tested with VVRA and CVRA over 2 different sessions. The total number of head turns prior to habituation, hit rate (response consistency), false alarm rate, and sensitivity for each reinforcement condition were evaluated.
  
  
  RESULTS
  No significant differences were found between the 2 reinforcement methods for total number of head turns, hit rate, false alarm rate, or sensitivity. Overall, results showed no difference between the 2 reinforcer conditions in infants 7-16 months of age.
  
  
  CONCLUSIONS
  The results of the present study suggest that infants in the 7- to 16-month-old age range respond similarly to VVRA and CVRA as measured by response consistency and false alarm rate. VVRA is, therefore, a viable option for testing hearing in infants. However, prior to clinical implementation, the effectiveness of VVRA should be explored in infants with hearing loss.
