Three experiments involving 128 infants studied whether and how novel words influence object categorization in 12- to 13- month-old infants. Data revealed that a linkage between words and object categories emerged early enough to be a guide in infants' efforts to map word meanings. (SLD)

What role does contextual information play in children's early word comprehension? Using an inter-modal preferential looking task, we investigated how different background contexts influence children's looking times before and after an image has been named. Prior to the experiment, early comprehension of words was assessed using parental…

Confirms previous findings that young children do not have an adequate concept of what constitutes the spoken "word." (RB)

When encountering a word for the first time, information about it is connected to information from the context. There are four levels of word knowledge: never having seen it before; having heard of it but not knowing what it means; recognizing it in context; and knowing it. A full and flexible knowledge of a word involves understanding the core…

There are problems in interpreting the naming behavior of children. Children may misname a word because the word is absent from their vocabulary, because it is not yet firmly established, or because of a word retrieval or lexical assessing problem. Preliminary results are reported of an experimental technique designed to account for these…

Reveals that the impact of training children with learning disabilities to verbalize a word-attack strategy was not as significant as had been suggested by previous research. (FL)

To understand the development of number-word construction, students in grades 1, 3, 5, and 7 named and counted from a set of numbers into the billions in two studies. Findings are discussed both in relation to children's growing knowledge of the number system and to vocabulary development. (Author)

Forty third-graders and an equal number of sixth-graders listened to a list of words and for each word had to indicate, by saying "old" or "new," whether it had appeared before on the list or not. The subjects gave more erroneous "old" responses to words which were semantically or phonetically related to previously heard words than to control…

Describing what children at the preoperational stage know about writing, spelling, and words, the authors make specific recommendations for ways language arts teachers can build instruction that is based on this knowledge. (SK)

Discusses three experiments investigating the development of word-by-word comprehension in 5-, 7-, and 10-year olds. Subjects monitored for target words in a sentence. Variable included types of monitoring tasks and distribution and context of target words. Results are discussed in terms of the types of comprehension processes various tasks…

People of ages 4, 6, 8, 10, 20 and 70 years named pictures selected to represent the entire range of lexical consensus among 20-year-olds. Consensus within each group increased with age, up to 20. Data indicate words coding culturally important events are acquired earliest. (CHK)

Word comprehension tests were given to 24 infants at 2-month intervals. Parents of 18 of the infants kept a diary of the children's verbal production. Comprehension scores revealed a vocabulary spurt for some children. The presence of a comprehension spurt was associated with a word production spurt. (BC)

Two investigations of the acquisition of the meaning of "always" and "never," and "always,""never,""usually,""seldom," and "sometimes" are discussed. Results demonstrate that the acquisition sequence of meanings of related words may vary among children at the beginning, but become consistent in later acquisition. (CHK)

This investigation deals with developmental changes in children's ability to process graphological features of words. The graphological features studied were letter positions and word shape. (Author/DEP)
