TL;DR: This article investigated the phenomenon of how children acquire grammatical morphology, including both function words and inflectional morphemes, and found that the phonology and prosodic structure of a language interact with how and when grammatical morphologies are perceived/comprehended and produced.

Abstract: This chapter investigates the phenomenon of how children acquire grammatical morphology, including both function words and inflectional morphemes. In particular, it shows that the phonology and prosodic structure of a language interact with how and when grammatical morphemes are perceived/comprehended and produced. With respect to function words such as articles, it shows that those that can be prosodified as part of a foot/prosodic word tend to be produced first, as do inflectional morphemes occurring at the ends of phrases/utterances. The fact that similar patterns of prosodic interactions between the perception/production of grammatical morphology and the lexicon appear crosslinguistically suggests that these are robust phenomena. This has both theoretical implications for understanding the interactions between children’s developing linguistic competencies at the phonology/syntax interface, as well as practical implications for clinicians working with children with language delay.

Effects of Prior Encounter and Global Discourse Bias on the Processing of Lexically Ambiguous Words: Evidence From Eye Fixations
TL;DR: For instance, the authors found that readers' gaze durations are longer on biased homographs (those having one highly dominant meaning) than on unambiguous control words when the preceding context instantiates the homograph's subordinate meaning.

Neural representations of abstract stimulus features in the human brain as reflected by the mismatch negativity.
TL;DR: It was concluded that besides physical stimulus properties, abstract stimulus features are also encoded in the neural representations of sensory memory.

When we think about thinking: the acquisition of belief verbs.
TL;DR: The findings support the position that the informational demands of mapping, rather than age-related cognitive deficiency, can bear much of the explanatory burden for the learning problems posed by abstract words.

The perceptual consequences of within-talker variability in fricative production
TL;DR: Listeners were presented with natural /s/ and /S/ tokens for identification, under ideal listening conditions, and slower response times were found for speakers whose productions were more variable than for speakers with more internal consistency in their speech, suggesting that the degree of variability, not just the existence of it, may be the more critical factor in perception.

Input and uptake at 7 months predicts toddler vocabulary: the role of child-directed speech and infant processing skills in language development
TL;DR: Both repetitiveness in maternal input and the child's speech segmentation skills at age 0;7 predicted language outcomes at 2;0; moreover, while these factors were somewhat inter-related, they each had independent effects on toddler vocabulary skill, and there was no interaction between the two.
