本研究将Biederman（1987）的成分识别（RBC）理论扩展到分析不完整视觉呈现物体识别的年龄差异。RBC理论预测，如果有足够的基本结构信息，物体在碎片化条件下是可识别或可恢复的。由于在顶点和重叠区域的基本结构特征的遗漏或阻碍，物体变得不可恢复。15名年轻人和15名老年人参加了一项研究，研究碎片的数量（25%，45%，65%）和类型（可恢复，不可恢复）对物体命名的影响。认知不完整物体的能力下降与碎片的数量有关，但碎片的类型并不影响老年人的表现。对于年轻的成年人，性能的准确性受到破碎的数量和类型的影响，与Biederman的RBC理论一致。这些结果被解释为表明，与年龄相关的知觉闭合性能下降与非结构性因素，如增强退化或丢失的视觉信息的能力。
This study extended aspects of Biederman's (1987) recognition-by-components (RBC) theory to the analysis of age differences in the recognition of incomplete visually-presented objects. RBC theory predicts that objects are recognizable or recoverable under conditions of fragmentation if a sufficient amount of essential structural information remains available. Objects are rendered nonrecoverable by the omission or obstruction of essential structural features at vertices and areas of concavity. Fifteen young adults and 15 older adults participated in a study of the effects of amount (25%, 45%, 65%) and type of fragmentation (recoverable, nonrecoverable) on object naming. Age-related declines in recognizing incomplete objects were associated with the amount of fragmentation, but type of fragmentation did not affect the performance of older adults. For the young adults, accuracy of performance was affected by both amount and type of fragmentation, consistent with Biederman's RBC theory. These results were interpreted as suggesting that age-related declines in perceptual closure performance have to do with non-structural factors such as the ability to inferentially augment degraded or missing visual information.
