Beginning with the classic work of Shepard, Hovland, & Jenkins (1961), Type II visual patterns (e.g., exemplars are large white squares OR small black triangles) have held a special place in investigations of human learning. Recent research on Type II "linguistic" patterns has shown that they are relatively frequent across languages…

Every environment contains infinite potential features and correlations among features, or patterns. Detecting valid and learnable patterns in one environment is beneficial for learners because doing so lends predictability to new environments where the same or analogous patterns recur. However, some apparent correlations among features reflect…

This study explored the sensitivity of 20 10- to 11-month-old infants to the phonological characteristics of their native language. Tone-probe event-related potentials were obtained for subjects listening to a story, either with normal English function morphemes or modified with atypical function morphemes. Results suggest that the 11-month-olds,…

Sixteen adults with language/learning disabilities (L/LD) and 16 controls participated in a study testing sensitivity to word order cues that signaled grammatical versus ungrammatical word strings belonging to an artificial grammar. Participants with L/LD performed significantly below the comparison group, suggesting that this skill is problematic…

Fourteen children (ages 4-6) with specific language impairment produced sentences containing reduced or unreduced disyllabic proper names. Acoustic analyses revealed a significantly longer duration for verb-onset to name-onset of sentences containing the reduced name, indicating that although segmental material is omitted, an acoustic trace…
