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

purposePerceptual training offers a promising, listener-targeted option for improving intelligibility of dysarthric speech. Cognitive resources are required for learning, and theoretical models of listening effort and engagement account for a role of listener motivation in allocation of such resources. Here, we manipulate training instructions to enhance motivation to test the hypothesis that increased motivation increases the intelligibility benefits of perceptual training.

methodAcross two data collection sites, which differed with respect to many elements of study design including age of speaker with dysarthria, dysarthria type and severity, type of testing and training stimuli, and participant compensation, 84 neurotypical adults were randomly assigned to one of two training instruction conditions: enhanced instructions or standard instructions. Intelligibility, quantified as percent words correct, was measured before and after training.

resultsListeners who received the enhanced instructions achieved greater intelligibility improvements from training relative to listeners who received the standard instructions. This result was robust across data collection sites and the many differences in methodology.

conclusionsThis study provides evidence for the role of motivation in improved understanding of dysarthric speech-increasing motivation increases allocation of cognitive resources to the learning process, resulting in improved mapping of the degraded speech signal. This provides empirical support for theoretical models of listening effort and engagement. Clinically, the results show that a simple addition to the training instructions can elevate learning outcomes.
