ABSTRACT Working memory is crucial in cognitive functioning, and environmental cues may enhance its performance. This study examines the role of visual support in promoting and aiding memory strategy. The aim was to determine whether visual placeholders can scaffold mnemonic processes for children and adults. Experiment 1 assessed the ability of 3.5 – to 6-year-olds to use visual support for visuo-spatial rehearsal, while Experiment 2 examined the influence of visual support in adults’ working memory. Children demonstrated improved recall with visual support, which could indicate the early use of visuo-spatial rehearsal strategies. Young adults, especially those with lower working memory spans, also benefited from visual placeholders, suggesting that environmental support promotes and scaffold strategy implementation. The findings revealed that visual support plays a role in enhancing working memory performance. It facilitates rehearsal strategies, benefiting individuals across the lifespan, especially those with less efficient mnemonic strategies.
