Paragraph 4： Two additional techniques of studying infant perception have come into vogue. The first is the habituation-dishabituation technique, in which a single stimulus is presented repeatedly to the infant until there is a measurable decline (habituation) in whatever attending behavior is being observed. At that point a new stimulus is presented, and any recovery (dishabituation) in responsiveness is recorded. If the infant fails to dishabituate and continues to show habituation with the new stimulus, it is assumed that the baby is unable to perceive the new stimulus as different. The habituation-dishabituation paradigm has been used most extensively with studies of auditory and olfactory perception in infants. The second technique relies on evoked potentials, which are electrical brain responses that may be related to a particular stimulus because of where they originate. Changes in the electrical pattern of the brain indicate that the stimulus is getting through to the infant's central nervous system and eliciting some form of response. 25.In paragraph 4, what does the author suggest about the way an infant's brain perceives stimuli? ○An infant's potential to respond to a stimulus may be related to the size of its brain. ○Changes in the electrical patterns of an infant's brain are difficult to detect. ○Different areas of an infant's brain respond to different types of stimuli. ○An infant is unable to perceive more than one stimulus at a time. 這題解答寫Ａ，當時情急之下所了Ｃ，檢討時才發現根本是not mention的錯誤選項但回去文章裡找好像也找不到正確答案的敘述請問文章中那裏有提及嬰兒對刺激的反應是和他大腦的大小有關? 謝謝~ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.136.211.19
