Latent Network Analysis of Central Processing

小行星9601465 一个人在执行一项任务时，比如在屏幕上寻找一个特定大小和形状的符号，他必须进行心理过程，比如感知、记忆和决定。 在某些情况下，这些过程必须按照一定的顺序进行，例如，当一个过程的输出是另一个过程的输入时。 在其他情况下，可能有几种方法可以对过程进行排序，例如，如果要做出两个响应，并且可以选择先做出哪个响应。 这些选择有时会导致调度问题。 主要的调度冲突产生于工作记忆空间的竞争，其中与正在进行的任务相关的信息被保存了很短的时间。 所有的证据都表明，工作记忆的空间是非常有限的，所以通常只有一个过程可以使用它积极的时间。 例如，有证据表明心算不能与搜索记忆同时进行。 本研究将探讨某些过程可以同时使用工作记忆的可能性。 我们感兴趣的主要过程是那些为不连续的过程准备或建立工作记忆空间的过程。 可以说，这些准备过程是在幕后进行的， 对空间的要求很高。 特别令人感兴趣的筹备进程是那些为即将到来的进程安排时间的进程。 有待检验的一个假设是，即将到来的过程的准备工作是否可以与其他正在进行的过程同时进行。 如果不能弄清楚内隐心理过程是同时进行还是按顺序进行的，如果是按顺序进行的，那么这项研究就不可行。 在以前的研究中开发了一种方法，即潜在网络理论。 它基于反应时间和其他性能指标。 虽然这项研究在本质上是基础性的，但它将帮助我们了解人类在各种实际领域中出现的各种快速任务中的表现，例如复杂设备的操作，以及这些任务（和相关设备）的设计，以便它们建立在必须执行这些任务的人类的能力之上。 ***

9601465 SCHWEICKERT Someone performing a task such as searching a screen for a symbol of a certain size and shape must carry out mental processes, such as perceiving, remembering, and deciding. In some situations the processes must be carried out in a certain order, for example when the output of one process is the input to another. In other situations, there may be several ways in which the processes could be ordered, for example, if two responses are to be made and there is a choice about which response to make first. These choices sometimes lead to scheduling problems. Major scheduling conflicts arise from competition for space in working memory, where information relevant to an ongoing task is held for a short time. All evidence points to the conclusion that working memory space is very limited, so that usually only one process can use it actively at a time. For example, there is evidence that mental arithmetic cannot be carried out simultaneously with a search of memory. This research will explore the possibility that certain processes can use working memory simultaneously. The main processes of interest are those that prepare or set up the working memory space for processes that are immanent. These preparation processes operate behind the scenes, so to speak, and may not make intensive demands for space themselves. Preparatory processes of special interest are those that schedule the upcoming processes. One hypothesis to be tested is whether preparation of upcoming processes can be carried out simultaneously with other ongoing processing. This research would not be feasible if it were not possible to figure out whether covert mental processes are executed concurrently or sequentially, and, if they are sequential, what the order of execution is. A methodology for doing this, Latent Network Theory, was developed in previous research. It is based on reaction time and other performance measures. While this research is fundamental in na ture, it will help us understand the performance of humans in the sorts of speeded tasks that arise in all manner of practical arenas, such as the operation of complex equipment, and the design of those tasks (and the relevant equipment) so that they build on the capabilities of the humans who will have to perform them. ***
