This commentary critiques Ambridge's radical exemplar model of language acquisition using research from the Longitudinal Study of Early Language, which has tracked the language development of 30+ children with Autism Spectrum Disorders (ASD) since 2002. This research has demonstrated that the children's capacity for abstraction at the grammatical…

Using the blocked-translation paradigm with healthy participants, we examined Crutch and Warrington's hypothesis that concrete and abstract concepts are organized by distinct principles: concrete concepts by semantic similarities and abstract ones by associations. In three experiments we constructed two types of experimental blocking (similar…

An initial description of the links between cognitive input, discourse rules, and the rules of sentence grammar is made, based on a technique developed for observing the translation of cognitive input into language in a spontaneous, practical speech event: descriptions of the lay-outs of apartments.

Nouns are generally recalled and recognized better in memory tasks, although several theoretical positions and a variety of empirical tasks indicate the importance of verbs to sentences. To try to resolve this paradox, several experiments were designed to explore the efficiency of various sentence elements as cues in recognition memory. Subjects…

Experiments are reported in which semantically interrelating sentences were presented to subjects as discrete items, and inference tests were given to measure the degree to which the similar information had been stored in the same memory system. Results suggest that verbal information is sometimes encoded into an episodic system. (Author/RM)

The hypothesized relationship between an individual's age, educational background, and ability to understand aspects of semantic ambiguity was investigated in this study. The 90 subjects included ten students in each of grades two, four, six, eight, and ten, as well as ten college undergraduates, ten graduate students, ten high school graduates,…

Evidence is provided to refute the suggestion, made by Macnamara et al. (1976), that four-year-old children perform logical operations corresponding to formal logic upon the sentential components of implicative verbs to produce indirect implications. It is argued that children use past knowledge plus additional premises to derive indirect…

Presents a rebuttal to Hidi and Hildyard's (1976) criticism of Macnamara et al.'s (1976) assertion regarding the ability of four-year-old children to grasp implicatives and presuppositions. (AM)

The hypothesized ability of adult native speakers to understand linguistic ambiguity was tested. An approach developed to determine linguistic competence tested the ability of 90 participants in individual interviews to interpret sentences having the potential for multiple interpretations. The hypothesis was not supported by the data. A hierarchy…

The range of meanings of "big" and "little" that mothers and their three children under age two expressed in relatively natural communication situations was studied. Longitudinal data from transcripts of conversations of middle-class mothers and their children were analyzed along with diary records kept by parents of their children's use of size…
