A secondary task is not always costly: Context-based guidance of visual search survives interference from a demanding working memory task.
Article in British journal of psychology (London, England : 1953), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Repeatedly encountering a visual search display with the target located at a fixed position relative to the distractors facilitates target detection, relative to novel displays - which is attributed to search guidance by (acquired) long-term memory (LTM) of the distractor 'context' of the target. Previous research has shown that this 'contextual cueing' effect is severely impeded during learning when participants have to perform a demanding spatial working memory (WM) task concurrently with the search task, though it does become manifest when the WM task is removed. This has led to the proposal that search guidance by LT context memories critically depends on spatial WM to become 'expressed' in behaviour. On this background, this study, of two experiments, asked: (1) Would contextual cueing eventually emerge under dual-task learning conditions if the practice on the task(s) is extended beyond the short training implemented in previous studies? and given sufficient practice, (2) Would performing the search under dual-task conditions actually lead to an increased cueing effect compared to performing the visual search task alone? The answer is affirmative to both questions. In particular, Experiment 1 showed that a robust contextual cueing effect emerges within 360-720 dual-task trials as compared to some 240 single-task trials. Further, Experiment 2 showed that when dual- and single-task conditions are performed in alternating trials blocks, the cueing effect for the very same set of repeated displays is significantly larger in dual-task blocks than in single-task blocks. This pattern of effects suggests that dual-task practice eventually leads to direct, or 'automatic', guidance of visual search by learnt spatial LTM representations, bypassing WM processes. These processes are normally engaged in single-task performance might actually interfere with direct LTM-based search guidance.
