Bite rate, sip rate, and concurrent activities of six 7-yr-old children, three obese and three nonobese, were observed at lunchtime over a six-month period. A procedure for decreasing bite rate, putting eating utensils down between bites, was implemented in a multiple-baseline across-subjects design. Sip rates and concurrent activities were observed to assess behavioral covariations. In addition, bite rate and amount of food completed were computed over six food categories to analyze food preferences. Results indicated the control of bite rate acorss all subjects, with a significant reduction in amount of food consumed. Correlations between the response classes indicated they were at least partially independent. Differences in eating behavior of obese and nonobese subjects were observed for breadstuffs and milk drinking.
在六个月的时间里，观察了六名7岁儿童（三名肥胖儿童和三名非肥胖儿童）午餐时的咬食速率、啜饮速率和同时进行的活动。采用多基线跨被试设计实施了一种降低咬食速率的程序，即在咬食之间放下餐具。观察啜饮速率和同时进行的活动以评估行为协变。此外，计算了六种食物类别上的咬食速率和吃完的食物量，以分析食物偏好。结果表明所有被试的咬食速率都得到了控制，食物摄入量显著减少。反应类别之间的相关性表明它们至少部分独立。在面包类食物和喝牛奶方面，观察到肥胖和非肥胖被试在进食行为上存在差异。
