在三项研究中，采用新奇偏好方法，研究了3个月大婴儿在1个月或3个月的保持间隔内对物体运动的记忆。在熟悉的对象经历两种类型的运动之一，视觉偏好的新的运动后，1分钟，1天，1个月（实验1，N = 120）和1分钟，1天，2周，1个月（实验2，N = 74）的保留间隔进行了评估。这两项研究的结果表明，一个显着的偏好在1分钟的延迟，一个显着的偏好熟悉的运动在1个月的延迟，并没有偏好在中间的保留间隔。在实验3中，记忆3个月的间隔后进行评估，并再次，一个显着的熟悉偏好。这些结果表明，物体运动的记忆持续时间跨越保留间隔1和3个月，新奇和熟悉的偏好与保留时间相互作用。提出了一个四相函数的视觉偏好和保留时间。第一阶段是近期记忆，其特征是对新奇事物的偏好;第二阶段是中间记忆，这是一个过渡期，其特征是没有视觉偏好;第三阶段是远程记忆，其特征是对熟悉事物的偏好;第四阶段是不可访问记忆，其特征也是没有偏好。在中间保留时间的过渡期的发现表明，零偏好不一定被视为遗忘的证据。相反，更长的保留时间间隔应包括解释无效的结果中获得的新奇偏好方法。(C)出版社：Academic Press
Memory for object motion in 3-month-old infants was investigated across retention intervals of 1 or 3 months in three studies using a novelty preference method. Following familiarization to an object undergoing one of two types of motion, visual preferences for the novel motion were assessed after retention intervals of 1 min, 1 day, and 1 month (Experiment 1, N = 120) and 1 min, 1 day, 2 weeks, and 1 month (Experiment 2, N = 74). Results of both studies indicated a significant preference for the novel motion at the 1-min delay, a significant preference for the familiar motion at the 1-month delay, and no preferences at the intermediate retention intervals. In Experiment 3, memory was assessed after a 3-month interval and again, a significant familiarity preference was obtained. These results demonstrate that memory for object motion lasts across retention intervals of 1 and 3 months and that novelty and familiarity preferences interact with retention time. A four-phase function relating visual preferences and retention time was proposed. Phase 1, recent memory, is characterized by a novelty preference; phase 2, intermediate memory, is a period of transition characterized by no visual preference; phase 3, remote memory, is characterized by a familiarity preference; and phase 4, inaccessible memory, is also characterized by no preference. The finding of a transition period at intermediate retention times suggests that null preferences should not necessarily be taken as evidence of forgetting. Rather, more extended retention intervals should be included to interpret null findings obtained in the novelty preference method. (C) 1995 Academic Press, Inc.
