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

In this article we explore the use of Granger Causality as a method to shed light on causal relationships in studies on (second) language acquisition. Understanding such relationships remains a central challenge in longitudinal SLA research, where both learner variables and measures of linguistic development interact and evolve dynamically over time. We first explain the concept of Granger Causality and show how the method works, before providing an illustration using weekly measures of L2 development (C-Test performance and speech fluency) and individual difference variables (operation span, motivation and wellbeing) to explore their possible causal relationships in a longitudinal study with later-life language learners. The results reveal several asymmetric patterns. The findings are discussed in relation to the existing literature on later-life language learning and demonstrate that Granger causality is a valuable method for examining the directionality of relationships between variables in longitudinal data.
