Implicit Learning of Adjacent and Non-Adjacent Dependencies: Relationships with Measures of Language, Attention, and Working Memory

Learning non-adjacent sequential dependencies only occurs under favorable circumstances (e.g., Lany & Gomez, 2008). However, both adjacent and non-adjacent dependencies (AD and NAD) are learned in natural language. Vuong et al. (2016) recently showed that adults learn visuo-verbal AD and NAD with training over multiple sessions. We tested whether adults could learn AD and NAD together with spatial and verbal stimuli during a single session and whether a second session would increase performance. We also examined the relationship between this learning and language, attention, and working memory. Participants reproduced two types of “grammatical” sequences: visuo-spatial with sequential stimuli in four locations, and visuo-verbal with sequential syllables. Each contained AD and NAD. Participants were tested for incidental learning on reproduction of novel sequences, half grammatical and half ungrammatical, containing either violations of AD or NAD. The procedure was repeated on a second day. Results revealed that grammatical sequences were learned better than ungrammatical for both AD and NAD in both visuo-spatial and visuo-verbal sequences within a single session. AD learning was better than NAD. Furthermore, learning of NAD decreased over time, possibly due to increased exposure to ungrammatical sequences suggesting NAD learning is more easily disrupted than AD. Finally, NAD learning was positively correlated with language measures for both spatial and verbal tasks whereas AD performance on both visuo-spatial and visuo-verbal tasks was negatively associated with working memory and attention span in the opposite domain. These findings highlight the nuanced relationship between AD and NAD learning and specific cognitive processes.
