Structural priming is the tendency to repeat syntactic structure across sentences and can be divided into short-term (prime to immediately following target) and long-term (across an experimental session) components. This study investigates how nondeclarative memory could support both the transient, short-term and the persistent, long-term structural priming effects commonly seen in the literature. We propose that these characteristics are supported by different subcomponents of nondeclarative memory Perceptual and conceptual nondeclarative memory respectively. Previous studies have suggested that these subcomponents age differently, with only conceptual memory showing age-related decline. By investigating how different components of structural priming vary across the life span, we aim to elucidate how nondeclarative memory supports 2 seemingly different components of structural priming. In 167 participants ranging between 20 and 85 years old, we find no change in short-term priming magnitude and performance on perceptual tasks, whereas both long-term priming and conceptual memory vary with age. We suggest therefore that the 2 seemingly different components of structural priming are supported by different components of nondeclarative memory. These findings have important implications for theoretical accounts of structural priming.

In 2 preregistered experiments, we asked whether university students are sensitive to 1 effect of part of speech that has been observed by linguists that content words (e.g., the noun inn) must be spelled with at least 3 letters, whereas function words (e.g., the preposition in) may have only 2 letters. Participants heard VC (vowel-consonant) and consonant-vowel-consonant (CVC; consonant-vowel-consonant) nonwords that were used as nouns (content words) or prepositions (function words). Participants either spelled the items on their own or chose between options with single and double final consonants (e.g., ib vs. ibb). Participants in the choice task favored final consonant doubling for VCs that were used as nouns. They usually chose single final consonants for VCs that were used as prepositions and for CVCs. Effects of word class were also found in the spelling production task. Final consonant doubling was less common in the production task than the choice task, reflecting participants' reluctance to produce this relatively uncommon spelling pattern. Our results support the view that spelling performance reflects the combined influences of multiple patterns, both phonological and nonphonological.

Thus, making optimal use of visual working memory requires continual, moment-to-moment monitoring of its fidelity High-fidelity representations can be relied upon, whereas incomplete or fuzzy representations must be refreshed or ignored. Previous work showed that adults track the fidelity of their visual working memory. Here, we asked whether children, whose capacities for visual working memory are undergoing protracted development, also can do so. We showed 5- and 6-year-olds sets of 2-5 single-feature (Experiment 1) or multifeature (Experiment 2) objects hidden simultaneously in separate locations. We asked children to recall the location of one of the objects, then bet 0-3 resources on whether they were correct. In both experiments, we found that children's confidence in their visual working memory, as indexed by their bets, was correlated with their accuracy on each trial, controlling for task difficulty Children bet higher when they were correct and lower when they were incorrect. Our results suggest that metacognitive awareness o
