Unformatted text preview: 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. 13. 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? 14 在 Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that not presented in the passage or are minor ideas in the passage. This question is worth 2 points. Researchers use a number of techniques to determine how infants respond to changes in their environment ● ● ● Answer choices ○Data from observational methods must be confirmed through multiple studies. ○New techniques for studying infant perception have improved the accuracy with which researchers observe and quantify infant responses ○Indirect observation is most accurate when researchers use it to test auditory and olfactory perception in neonates. ○Visual indicators such as turning the head, blinking the eyes, or crying remain the best evidence of an infant’s perceptual abilities. ○Pacifiers are commonly used in studies to calm an infant who has been presented with excessive stimuli. ○Sophisticated techniques that have aided new discoveries about perception in the neonate continue to be indirect measures. 386 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 在在在在在 1. ○3 2. ○3 3. ○1 4. ○3 5. ○2 6. ○1 7. ○2 8.○4 9. ○4 10. ○1 11. ○3 12. ○4 13. ○2 14. ○1, 2, 6 387 Mail@liuwenyong.com 在在在在在在 www.liuwenyong.com 在在在在在在在在在在在在在在在,在在在在在在在在在在 在在在在 在在在在在在在在在在在 在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在 在 在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在在...
