摘要：This paper presents the results of two studies that tested the effects of question tone and form on responses to open-ended questions in face-to-face surveys. The studies compared the effects on length of response (number of words) and number of ideas, of using single neutral questions, questions combining positive and negative cues, and double questions that used different cues. The results suggest that longer responses, and a greater number of ideas, can be elicited by using different cue tones in separate questions rather than combining them in a single long question. For combined questions, the ordering of the cue tones had a pronounced affect on the tone of the ideas elicited, but not on the total number of ideas generated
