为了研究咀嚼期间的侧向食团放置，称为咀嚼侧向偏好，15只雄性和10只雌性咀嚼无糖口香糖15、20和25 s，并对右侧或左侧食团放置进行目视检查。在三个系列的观察中，右侧或左侧推注位置之间没有显著差异。连续三次对单个受试者的抽查表明，横向偏好是随机发生的。然而，信息上的一个有利的咀嚼侧预测相当可靠的一侧观察到的咀嚼侧偏好。观察到的横向偏好不能预测手偏侧。据推测，一致和占主导地位的右侧或左侧偏好主要是动机性咀嚼行为的表达。
To study lateral bolus placement during mastication, referred to as masticatory lateral preference, fifteen males and ten females chewed sugarless gum for 15, 20 and 25 s, and visual inspections were done of either right or left side bolus placements. In each of three series of observations, there were no significant differences between right or left side bolus placements. Three consecutive spot checks, in single subjects, showed that lateral preference occurred at random. However, information on a favored chewing side predicted fairly reliably the side of observed masticatory lateral preference. Observed lateral preference could not be predicted from hand laterality. Consistent and predominant right or left lateral preference was, presumably, an expression of mainly motivational chewing behavior.
