What a picture selection task can tell us about scalar implicature processing? A neuroimaging investigation.

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.
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
Pragmatic inferences beyond the literal meaning of utterances occur with weak scalar expressions, such as 'some', which has a logical meaning of 'some and possibly all' and a pragmatic meaning of 'some but not all', derived through a scalar implicature (SI). Such processing is assumed to involve linguistic and extra-linguistic processes, including Theory of Mind and executive functions. Previous neuroimaging studies used truth value evaluation tasks to study SI processing, showing involvement of the left inferior frontal gyrus (IFG), left anterior middle frontal gyrus (MFG) and medial frontal gyrus (MeFG)/anterior cingulate cortex (ACC). This study used a picture selection task to better understand the role of these regions in SI processing. A region of interest analysis showed differences between a condition that promoted an implicature (with a weak scalar expression) and a condition that did not (with a strong scalar expression) only in the MeFG/ACC, also identified in a complementary whole-brain analysis (together with posterior activations). Based on the differences between processes related to truth value evaluation tasks and picture selection tasks, we propose that the IFG is linked to access to alternatives, the anterior MFG is associated with response-related processing, and the MeFG/ACC is associated with Theory of Mind.This article is part of the theme issue 'At the heart of human communication: new views on the complex relationship between pragmatics and Theory of Mind'.
