There are different views in the literature about the number and inter-relationships of cognitive domains (such as memory and executive function) and a lack of understanding of the cognitive processes underlying these domains. In previous publications, we demonstrated a methodology for formulating and testing cognitive constructs for visuo-spatial and verbal recall tasks, particularly for working memory task difficulty where entropy is found to play a major role. In the present paper, we applied those insights to a new set of such memory tasks, namely, backward recalling block tapping and digit sequences. Once again, we saw clear and strong entropy-based construct specification equations (CSEs) for task difficulty. In fact, the entropy contributions in the CSEs for the different tasks were of similar magnitudes (within the measurement uncertainties), which may indicate a shared factor in what is being measured with both forward and backward sequences, as well as visuo-spatial and verbal memory recalling tasks more generally. On the other hand, the analyses of dimensionality and the larger measurement uncertainties in the CSEs for the backward sequences suggest that caution is needed when attempting to unify a single unidimensional construct based on forward and backward sequences with visuo-spatial and verbal memory tasks.
文献中对于认知领域（如记忆和执行功能）的数量及相互关系存在不同观点，并且对这些领域背后的认知过程缺乏理解。在之前的出版物中，我们展示了一种用于制定和测试视觉空间及言语回忆任务认知结构的方法，特别是针对发现熵起主要作用的工作记忆任务难度。在本文中，我们将这些见解应用于一组新的此类记忆任务，即反向回忆方块敲击和数字序列。我们再次看到了针对任务难度的清晰且强大的基于熵的结构规范方程（CSE）。实际上，不同任务的CSE中的熵贡献幅度相似（在测量不确定性范围内），这可能表明在正向和反向序列以及更普遍的视觉空间和言语记忆回忆任务所测量的内容中存在一个共同因素。另一方面，对反向序列的维度分析以及CSE中较大的测量不确定性表明，在尝试基于正向和反向序列与视觉空间和言语记忆任务统一单个一维结构时需要谨慎。
