Decomposition of Implict Memory Processes

拟议中的实验分解了重复的组成部分 图片命名和类别样例生成中的启动。重复 图片命名中的启动通过减少之前的响应时间来表示 相对于新项目呈现的项目，以及类别样本中的启动 生成通过偏向于生产先前呈现的物品来指示，而不是 而不是新的物品。第一个具体目标是分解 有选择地促进图片命名和翻译。在实验1-2中， “加性因素”逻辑被用来测试选择性启动和 图片对象识别与词语检索部件的独立性 命名。在实验3中，将该方法扩展到分词识别 以及翻译的单词检索组件。第二个具体目标是 检查并解决任务启动过程中的不对称性。实验4-5 评估在需要公共对象的任务之间启动的对称性 识别或词提取过程和解决启动的不对称性 在给单词命名和给图片命名之间。实验6评估了 客体识别和词提取启动对脑功能的影响 随着时间的推移，图片命名便利化的耐力。第三个具体目标是 对启动类别关联所涉及的过程进行分解。 实验7-9评估概念可用性变化的贡献 以及在类别样本生成中从单词可用性到启动的变化。 大多数拟议的实验都是在双语参与者中进行的， 使用双语材料，以指定两个语音和 每个概念或图片的拼写不同的标签。更广泛的目标 这个项目的目的是更好地理解记忆的机制。通过 指定内隐记忆任务中启动的进程，它将是 有可能更好地确定患者表现出的记忆缺陷的性质 患有神经心理障碍。

The proposed experiments decompose the components of repetition priming in picture naming and in category exemplar generation. Repetition priming in picture naming is indicated by reduced response times for previously presented items relative to new items, and priming in category exemplar generation is indicated by a bias to produce previously presented items rather than new items. The first specific aim is to decompose priming mechanisms in picture naming and translation by selective facilitation. In Experiments 1-2, an "additive-factors" logic is used to test the selective priming and independence of object identification and word-retrieval components of picture naming. In Experiment 3, the method is extended to separate word identification and word retrieval components of translation. The second specific aim is to examine and resolve asymmetries in priming across tasks. Experiments 4-5 evaluate the symmetry of priming across tasks that require common object identification or word retrieval processes and resolve the asymmetry of priming between naming words and naming pictures. Experiment 6 evaluates the contributions of object-identification and word-retrieval priming to the endurance of picture naming facilitation over time. The third specific aim is to decompose processes involved in the priming of category associations. Experiments 7-9 evaluate the contributions of changes in concept availability and changes in word availability to priming in category exemplar generation. Most of the proposed experiments are conducted with bilingual participants, using bilingual materials in order to assign two phonologically and orthographically distinct labels to each concept or picture. The broader goal of this project is a better understanding of the mechanisms of memory. By specifying the processes that are primed in implicit memory tasks, it will be possible to better specify the nature of memory deficits exhibited by patients with neuropsychological disorders.
