Recent research suggests that the subjective feeling of conscious recollection is uniquely characterized by joint memory for several context features while merely familiar memories lack this property (Meiser, Sattler, & Weisser, 2008). In the present research we took the novel approach of extending the dual task paradigm to the simultaneous study of subjective retrieval experience (using the remember/know procedure) and joint memory for two orthogonal context features. While dual task load during encoding lead to reductions in the frequency of the subjective experience of conscious recollection and reductions in overall context memory, joint context memory was not affected. Furthermore, the relation of higher overall context memory for consciously recollected items than for familiar items was preserved even under dual task load. These results have import implications for theories of long-term feature binding and the processes involved in producing the experience of conscious recollection.
最近的研究表明，有意识回忆的主观感觉的独特特征是同时记忆几个上下文特征，而仅仅是熟悉的记忆缺乏这种特性（Meiser、Sattler 和 Weisser，2008）。在本研究中，我们采用了一种新颖的方法，将双任务范式扩展到同时研究主观检索体验（使用记住/知道程序）和两个正交上下文特征的联合记忆。虽然在编码过程中双重任务负荷会导致有意识回忆的主观体验的频率降低，并且整体上下文记忆减少，但联合上下文记忆不受影响。此外，即使在双重任务负荷下，有意识回忆的项目的整体上下文记忆高于熟悉项目的关系也得到了保留。这些结果对长期特征绑定理论和产生有意识回忆体验的过程具有重要意义。
