本研究的目的是评估言语编码的可用性及其对标准视觉矩阵任务（视觉模式测试）的影响。在一项试点研究中，参与者被展示了VPT的模式，并被要求说出其中的形状。口头代码的可用性总体较低，但是，一些模式导致了较高的平均数量的标签比其他。从产生最低平均标签数的那些模式中创建了测试的修改版本。然后，共有60名参与者参加了一项实验研究，该研究旨在评估口头编码的可用性是否会影响任务绩效。结果发现，修改后的版本导致了较低的视觉工作记忆广度比另一个版本，其中口头编码的可用性较高。这项研究证实，口头编码确实影响视觉矩阵任务的表现，但是，修改后的版本现在提供了一个选择的模式，从VPT口头编码已被限制。
The aims of the study were to assess the availability of verbal coding and its effect on performance in a standard visual matrix task, the Visual Patterns Test (VPT). In a pilot study, participants were presented with the patterns from the VPT and were asked to name the shapes within them. Availability of verbal codes was low overall; however, some patterns resulted in a higher mean number of labels than others. A modified version of the test was created from those patterns that had produced the lowest mean number of labels. A total of 60 participants then took part in an experimental study, which was carried out to assess whether or not the availability of verbal coding affects task performance. It was found that the modified version resulted in a lower visual working-memory span than that of another version in which the availability of verbal coding was higher. The study confirmed that verbal coding does influence visual matrix task performance; however, the modified version now offers a selection of patterns from the VPT where verbal coding has been limited.
