目前还不清楚气味记忆是否或在多大程度上受到大脑侧化过程的影响。在这项研究中，我们分别对30名左右手受试者的鼻子的左侧和右侧进行了12项匹配样本气味记忆测试，这些受试者的年龄、性别分布和总体嗅觉能力相当。对于每个测试项目，三个延迟间隔（10-，30-，和60-s）之一，穿插在闻到目标刺激和闻到第一个的四个响应的替代品。女性（而非男性）在鼻子左侧的表现明显好于右侧，可以想象，这反映了对左半球语义过程的更大依赖。在鼻子右侧接受第一次测试的受试者表现优于在鼻子左侧接受第一次测试的受试者。在以前的工作中，年龄相关的气味记忆测试分数递减。这些数据有助于辩论的作用，偏侧化的大脑过程中情节气味记忆，并建议一个标准化的匹配样本气味记忆任务的性能是由一些相互作用的因素。
It is not known whether, or to what degree, odor memory is influenced by lateralized brain processes. In this study, we administered a 12-item match-to-sample odor memory test separately to the left and right sides of the nose of 30 left- and 30 right-handed subjects of equivalent age, sex distribution, and overall general smell ability. For each test item, one of three delay intervals (10-, 30-, and 60-s) was interspersed between smelling the target stimulus and smelling the first of four response alternatives. Women, but not men, performed significantly better on the left than on the right side of the nose, conceivably reflecting greater reliance upon left-hemisphere semantic processes. Subjects who received the first test on the right side of the nose outperformed those who received the first test on the left side of the nose. As in previous work, an age-related decrement in odor memory test scores was present. These data contribute to the debate on the role of lateralized brain processes in episodic odor memory, and suggest that performance on a standardized match-to-sample odor memory task is influenced by a number of interacting factors.
