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

Previous research has demonstrated the influence of task-irrelevant reward on object-based attention in non-conflict contexts. However, it remains unclear whether object-based attention emerged and how task-irrelevant reward guide object-based attention in conflict contexts. Therefore, the present study adopted a variant of two-rectangle paradigm to investigate the impact of task-irrelevant reward on object-based attention in conflict contexts across three experiments. Experiment 1 observed object-based effects when combing the two-rectangle paradigm with the Stroop task. Experiment 2 used color character as target and found object-based effects in the incongruent-unrewarded condition, not in the incongruent-rewarded condition. The difference can be due to faster response in the incongruent-unrewarded condition for invalid same-object trials. Experiment 3 adopted monetary objects as target and observed reversed object-based effects in the incongruent-high-rewarded condition, not in the incongruent-low-rewarded condition. This was due to faster response in the incongruent-low-rewarded condition than in the incongruent-high-rewarded condition for invalid same-object trials. These findings demonstrated that task-irrelevant reward can affect the object-based attention in conflict contexts, and different types of rewards may share a common mechanism in their impact on object-based attention. Ultimately, this study provided further support for the attentional spreading theory.
