问题     Guthrie’s contiguity principle offers practical suggestions for how to break habits.
    One application of the threshold method involves the time young children spend on academic activities. Young children have short attention spans, so the length of time they can sustain work on one activity is limited. Most activities are scheduled to last no longer than 30 to 40 minutes. However, at the start of the school year, attention spans quickly wane and behavior problems often result. To apply Guthrie’s theory, a teacher might, at the start of the year, limit activities to 15 to 20 minutes. Over the next few weeks the teacher could gradually increase the time students spend working on a single activity.
    The threshold method also can be applied to teaching printing and handwriting. When children first learn to form letters, their movements are awkward and they lack fine motor coordination. The distances between lines on a page are purposely wide so children can fit the letters into the space. If paper with narrow lines is initially introduced, students’ letters would spill over the borders and students might become frustrated. Once students can form letters within the larger borders, they can use paper with smaller borders to help them refine their skills.
    The fatigue method can be applied when disciplining disruptive students who build paper airplanes and sail them across the room. The teacher can remove the students from the classroom, give them a large stack of paper, and tell them to start making paper airplanes. After the students have made several airplanes, the activity should lose its attraction and paper will become a cue for not building airplanes.
    Some students continually race around the gym when they first enter their physical education class. To employ the fatigue method, the teacher might decide to have these students continue to run a few more laps after the class has begun.
    The incompatible response method can be used with students who talk and misbehave in the media center. Reading is incompatible with talking. The media center teacher might ask the students to find interesting books and read them while in the center. Assuming that the students find the books enjoyable, the media center will, over time, become a cue for selecting and reading books rather than for talking with other students.
    In a social studies class some students regularly fall asleep. The teacher realized that using the board and overhead projector while lecturing was very boring. Soon the teacher began to incorporate other elements into each lesson, such as experiments, videotapes, and debates, in an attempt to involve students and raise their interest in the course.
Which of the following is not the example of applying the threshold method?
选项 A、Parents introduce spinach in small bites or mixed with a food that the child enjoys over time so that the child will not refuse to eat it.
B、Teachers introduce academic content in short blocks of time for young children and gradually increase session length but not to where students become frustrated or bored.
C、Paper with wider lines is first used and then paper with narrow lines is introduced step by step to help children learn printing and handwriting.
D、A child might be made to throw toys until it is no longer fun by his parents in order to change his behavior of repeatedly throwing toys.
答案D
解析 细节判断题。由第三段尾句可知，选项D所说扔玩具乃是与“疲劳法”相对应的例子，不是“门槛法”的实际例子。故答案为D。
