规范的词频和上下文变异性影响记忆在一系列情景记忆任务和地方的理论发展的限制。在四个实验中，我们独立操纵的词频和上下文的变化的目标（被生成的项目）和线索的线索回忆范式。我们发现，高频率的目标更好地回忆在纯和混合列表，即使上下文的变化保持不变。高频提示稍微更有效，但当上下文可变性保持不变时，这种好处就消失了。低情境变异性的线索对被试的绩效影响最大，而目标情境的变异性对被试的绩效影响不大。这些数据表明，与较少的预实验连接的话能够更好地隔离列表，并从内存中的项目的生成受益于频率，也许是由于容易产生共同的正字法和语音特征。对当前记忆模型的意义和未来模型的前景进行了讨论。(C)2010年爱思唯尔公司All rights reserved.
Normative word frequency and context variability affect memory in a range of episodic memory tasks and place constraints on theoretical development. In four experiments, we independently manipulated the word frequency and context variability of the targets (to-be-generated items) and cues in a cued recall paradigm. We found that high frequency targets were better recalled in both pure and mixed lists, even when context variability was held constant. High frequency cues were slightly more effective, but this benefit was eliminated when context variability was held constant. Low context variability cues were most effective while the context variability of the target had little effect on performance. The data suggest that words with fewer pre-experimental connections are better able to isolate the list and that generation of an item from memory benefits from frequency, perhaps due to the ease of generating common orthographic and phonological features. Implications for current models of memory and the prospects of future models are discussed. (C) 2010 Elsevier Inc. All rights reserved.
