We used the Multi-Item Localisation (MILO) task to examine search through two sequences. In Sequential blocks of trials, six letters and six digits were touched in order. In Mixed blocks, participants alternated between letters and digits. These conditions mimic the A and B variants of the Trail Making Test (TMT). In both block types, targets either vanished or remained visible after being touched. There were two key findings. First, in Mixed blocks, reaction times exhibited a saw-tooth pattern, suggesting search for successive pairs of targets. Second, reaction time patterns for vanish and remain conditions were identical in Sequential blocks—indicating that participants could ignore past targets—but diverged in Mixed blocks. This suggests a breakdown of inhibitory tagging. These findings may help explain the elevated completion times observed in TMT-B, relative to TMT-A.

搜索交替序列:使用MILO任务揭示工作记忆和抑制性标记机制

我们使用多项目本地化(MILO)任务检查了两个序列的搜索。在顺序试验中,依次触摸了六个字母和六个数字。在混合块中,参与者在字母和数字之间交替。这些条件模仿了“跟踪制作测试”(TMT)的A和B变体。在两种区块类型中,目标都消失了保持了触摸后可见。有两个关键发现。首先,在混合块中,反应时间呈现出锯齿状,建议搜索连续的目标对。第二,消失和保持条件的反应时间模式在顺序块中相同,表明参与者可以忽略过去的目标,但在混合块中却有所不同。这表明抑制性标签的分解。这些发现可能有助于解释相对于TMT-A,在TMT-B中观察到的完成时间增加。
