　　托福阅读句子插入题：Studying Infant Perception

　　【Paragraph 3】Observational assessment techniques have become much more sophisticated, reducing the　limitations just presented. Film analysis of the infant's responses, heart and respiration rate monitors, and nonnutritive　sucking devices are used as effective tools in understanding infant perception. ■Film analysis permits researchers to　carefully stuy the infant's responses over and over and in slow motion. ■Precise measurements can be made of the　length and frequency of the infant's attention between two stimuli. ■Heart and respiration monitors provide the　investigator with the number of heartbeats or breaths taken when a new stimulus is presented. ■Numerical increases　are used as quantifiable indicators of heightened interest in the new stimulus. Increases in nonnutritive sucking were　first used as an assessment measure by researchers in 1969. They devised an apparatus that connected a baby's　pacifier to a counting device. As stimuli were presented, changes in the infant's sucking behavior were recorded.　Increases in the number of sucks were used as an indicator of the infant's attention to or preference for a given visual　display.(Methods of Studying Infant Perception)

　　Look at the four squares [■] that indicate where the following sentence could be added to the passage.

　　The repetition allows researchers to observe the infant's behavior until they reach agreement about the presence and　the degree of the infant's response.

　　Where would the sentence best fit?
