部分报告的优势已经被用来识别短期形式的视觉存储(Sperling,1960)。我们采用部分报告范式,以测试视觉记忆是否可以保存,在很短的时间内,连续的输入和他们的时间顺序。在我们的实验中,两个连续的数组,每一个4位数,在每次审判。这两个阵列在空间上是重合的,并且每个阵列后面都跟着随机图案掩模。在部分报告条件下,听觉提示指示参与者是否应该报告第一个阵列或第二个阵列。结果一致显示部分报告的优势,其范围从16%到37%。延迟500毫秒的提示取消了大部分的这种优势,在该性能,然后类似于在整个报告的条件。随后的实验证实,部分报告的优势,我们测量是无法实现的(a)眼球运动,空间位移第二阵列相对于第一个;(B)提取信息从一个单一的快照包含一个完整的代表性的目标和面具;或(c)转移的一个子集的材料的语音存储。相反,我们建议观察者可以访问一个有限的,快速衰减的表示连续的视觉输入存储在时间序列。
The part-report advantage has been used to identify short-lived forms of visual storage (Sperling, 1960). We adopt the part-report paradigm to test whether visual memory can preserve, for a brief time, successive inputs and their temporal order. In our experiments, two successive arrays, each of 4 digits, were presented on each trial. The two arrays were spatially coincident, and each was followed by a random pattern-mask. In the part-report conditions, an auditory cue indicated whether the participant should report the first array or the second array. The results consistently showed a part-report advantage, which ranged in size from 16% to 37%. Delaying the cue by 500 ms abolished most of this advantage, in that performance was then similar to that in whole-report conditions. Subsequent experiments confirmed that the part-report superiority we measure is not achieved by (a) making eye movements that spatially displace the second array relative to the first; (b) extracting information from a single snapshot containing an integrated representation of the targets and masks; or (c) transferring a subset of material to a phonological store. We propose instead that observers have access to a limited, rapidly decaying representation of successive visual inputs stored in temporal sequence.
