1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The study of multitasking provides a unique window into the interaction of cognitive processes and systems and as such, into the cognitive architecture of the human mind. Previous studies reported that when participants speak and do something else at the same time, task performance often suffers. In the present study, we examine the mechanisms leading to such interference in multitasking in an ecological setting. We compare speaking performance across easy and difficult driving tasks and track measures of speech fluency and driving efficiency throughout the experiment. Interference is observed only under difficult driving conditions. Moreover, fluctuations in speaking performance predict fluctuations in driving performance and vice versa. When speaking efficiency decreases, so does driving efficiency. These findings have a straightforward explanation in accounts of dual-task interference, in which interference arises when task demands exceed available cognitive resources. They further suggest that when this limit is reached, the system downregulates resources on both tasks.
