The influence of number of features in the lexical decision task: a study in young and older adults.
Article in Cognitive processing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Prior research has shown that the number of semantic features (NoF) facilitates lexical decision performance in young adults, supporting the role of feedback activation from semantics to orthography in visual word recognition. However, evidence is scarce regarding possible changes in such processes throughout adulthood. The present study aims to investigate whether and to what extent the effect of NoF in visual word recognition changes with age. In total, 54 young adults (M = 21.4 years) and 52 older adults (M = 69.7 years) performed a go/no-go lexical decision task in which half of the words were associated with a high NoF and the other half with a low NoF. The main finding was that the NoF effect on lexical decision latencies modulated according to age. While both young and older adults exhibited a reliable benefit from high NoF words compared to low NoF words, this effect was smaller in older adults. This reduced facilitatory effect of NoF in older adults could not be attributed to differences in vocabulary or reading habits nor does it reflect age-related slowing, as the interaction between NoF and age groups remained after controlling for these individual differences. These findings suggest an age-related change in feedback activation from semantics to orthography in visual word recognition.
