English words may be divided conveniently into three categories: (1) those with a single root or base; (2) those with two bases; and (3) those which derive from syntactic structures. (Examples of words in the third category, which is the subject of this paper, are "off-the-record,""fly-by-night,""do-or-die.")…

Briefly discusses the concepts of "subject,""complement,""transitivity," and "intransitivity," contrasts the classes of complements in German and Italian based on identical criteria of classification, justifies such a classification for complements, and suggests didactic implications for the theory of…

Investigates the ability of 32 two-year-old children to use syntactic (i.e., form class) and semantic (i.e., type of referent) information to interpret the meaning of new nouns. Subjects were taught either a common noun or a proper noun for a block-like or animal-like object and then asked to select the named toy. (Author/CB)

Concludes that connective form class affects the learning of entire grammatical strings. (MH)

Three experiments examined role of lexical-form class in preschoolers' establishment of word-to-object mappings in referentially ambiguous situations. Results indicated that preschoolers were most likely to reject two words for the same object if both were proper names, and were less likely to reject if both were adjectives or if one was proper…

Prosody is complex and hierarchically organized but is realized as rhythmic movement sequences. Thus, observations of the development of rhythmic aspects of movement can provide insight into links between motor and language processes, specifically whether prosodic distinctions (e.g., feet and prosodic words) are instantiated in rhythmic movement…

This article addresses the benefits and problems in using adjective check list methodology to assess personality. Recent developments in this assessment method are reviewed, emphasizing seminal adjective-based personality tests (Gough's Adjective Check List), mood tests (Lubin's Depressive Adjective Test, Multiple Affect Adjective Check List),…

Methods for testing hypotheses concerning the regression parameters in linear models for the latent person parameters in item response models are presented. Three tests are outlined: A likelihood ratio test, a Lagrange multiplier test and a Wald test. The tests are derived in a marginal maximum likelihood framework. They are explicitly formulated…

In two experiments, we examined the role of labels in guiding preschoolers' extension of three types of familiar adjectives: emotional state adjectives, physiological state adjectives, and trait adjectives. On each trial, we labeled a target animal with one of the three different types of adjectives and asked whether these terms could apply to a…

Working memory has been implicated in the early acquisition of arithmetic skill, but the relations among different components of working memory, performance on different types of arithmetic problems, and development have not been explored. Preschool and Grade 1 children completed measures of phonological, visual-spatial, and central executive…

A request from the National Academies to prepare a presentation for a Workshop on Non-Technical Strategies to Protect Youth from Inappropriate Material on the Internet occurred before much was known about children, youth, and the Internet. The author's strategy was to investigate websites that cater to children and adolescents. The developmental…

We used a collaborative recall task to explore the nature and consequences of children's interaction with another child at the same or different age. Ninety-six children memorised word lists for recall. In a first condition children recalled collaboratively: in a pair with another child. In a second condition children recalled words independently…

In this study, we looked at priming effects produced by a short presentation (47ms) of morphologically complex pseudowords in French. In Experiment 1, we used as primes semantically interpretable pseudowords made of the grammatical combination of a root and a suffix, such as rapidifier ''to quickify.'' In Experiment 2, we used non-morphological…

In two conditioned lick suppression experiments using water-deprived rats, we examined the effects of following Pavlovian conditioned inhibition training (i.e., A-US/AX-NoUS) with pairings of the training excitor (A) and the unconditioned stimulus (US). Experiments 1 and 2 assessed the effects of this posttraining inflation treatment on Pavlovian…
