Aspect markers (AMs), temporal adverbs (TAs) and temporal nouns (TNs) are used by young Mandarin-speaking children to express time. However, the factors that affect the relative acquisition trajectories of these categories remains unclear. Accordingly, this study adopts Weist's time-concept model to examine the patterns of acquisition between and…

Purpose: The purpose of this study is to evaluate the effects of switching from in-person assessment to virtual assessment during the COVID-19 pandemic on the growth trajectories of children with hearing loss who are learning spoken language. Method: Sixty-eight children with typical hearing, 44 children with cochlear implants, and 47 children…

Purpose: Liquids are among the last sounds to be acquired by English-speaking children. The current study considers their acquisition from an articulatory timing perspective by investigating anticipatory posturing for /l/ versus /[voiced alveolar approximant]/ in child and adult speech. Method: In Experiment 1, twelve 5-year-old, twelve…

Infants have been described as "statistical learners" capable of extracting structure (such as words) from patterned input (such as language). Here, we investigated whether prior knowledge influences how infants track transitional probabilities in word segmentation tasks. Are infants biased by prior experience when engaging in sequential…

To explore early lexical development, the authors examined infants' sensitivity to changes in spoken syllables and objects given different temporal relations between syllable-object pairings. In Experiment 1, they habituated 2-month-olds to 1 syllable, /tah/ or /gah/, paired with an object in "synchronous" (utterances coincident with object…

In the position article to this volume, Klein outlines a set of questions that are relevant for furthering the linguist's understanding of what the cognitive and neural prerequisites for time in language might be. He also declares a certain skepticism regarding the likelihood that new methods from other disciplines will provide answers to those…

This study explores the effects that the age of onset (AO) of second language (L2) acquisition exerts on the attrition of first language (L1) event conceptualization patterns. The subjects studied are L1 Spanish-L2 Swedish bilinguals living in Sweden. The specific research questions addressed in the study concern the role of AO in endpoint…

McCormack and Hoerl's state of the art review of the development of temporal concepts from the end of infancy to the end of the fifth year shows that young children's conception of time is quite different from that of adults. Adults and 5-year-old children can construe an event from a range of temporal perspectives and can describe it from a…

Describes a study designed to explore the nature of early use of two forms of the perfect--the present perfect and the present perfect progressive--by children over three years old. Three factors were found to influence children's selective imitation and paraphrasing of the perfect: verb form, semantic sense of the perfect, and duration of the…

A study of the acquisition of time-related grammatical forms in Hebrew-speaking children looked at three kinds of information: (1) relative frequency of occurrence of different verb forms at different ages; (2) the relationship between tense-marking on verbs and the semantics of verbs used at different ages, and (3) the use of time adverbs…

Possible developmental asynchrony in children with specific language impairment (SLI) was investigated by comparing the development of temporal expressions of past reference in two linguistic domains in three- to five-year-olds. Results of the SLI children's performance suggest direct evidence for asynchronous language development. (Contains 40…

This study focuses on the development of the ability to talk about events in time -- to specify occurrence in time with reference to the present as well as to locate events in time with reference to each other. The child's learning of how to mark the different kinds of relationships between two events is discussed. This study of current relevance…

Analyses of the syntactic development of profoundly deaf children have revealed nonstandard stages in the evolution of verb phrases. A reading task required subjects (ages 12-13) to recognize the time-reference of simple sentences. Results supported the prediction that stage of development in verb-phrase production influenced perception.…
