TI  - Sensitization during visual habituation sequences: procedural effects and 
      individual differences.
PG  - 223-35
AB  - Although individual differences in visual habituation have long been interpreted 
      in terms of processes derived from comparator theory, research over the last 
      decade has suggested that arousal or arousability as manifest in sensitization 
      may contribute to infants' attentional profiles, and thus, to individual 
      differences in those profiles. We explored this possibility by habituating 
      4-month-old infants to 4 x 4, 10 x 10, or 20 x 20 checkerboards in a fixed-trial 
      paradigm. The first specific aim was to examine the attentional characteristics 
      of infants with habituation patterns showing sensitization versus those that did 
      not. The second specific aim was to determine whether patterns of attention 
      suggestive of sensitization effects reported in past research might be 
      attributable to the use of illuminated interstimulus intervals (ISIs). Trends 
      were observed for sensitization to occur more frequently with more complex than 
      with less complex checkerboards. Infants who showed looking patterns 
      characteristic of sensitization looked longer and did not habituate as readily as 
      infants who did not show sensitization. Finally, different ISIs did not engender 
      different levels of sensitization, but dark ISIs significantly increased infants' 
      looking times to stimuli during trials.
