This paper locates computational and behavioral studies of children's language learning in a theoretical framework; reviews four articles in this journal issue on learning word meanings and sounds and on setting grammatical parameters; highlights "autonomous bootstrapping" strategies that children use to represent uncertain linguistic…

In some psycholinguistic models, processing is characterized by generation of multiple outputs using information from higher processing levels. Such models are considered autonomous in word recognition domain but interactive in sentence processing domain. This confusion arises not from differences between lexical and syntactic processing, but from…

Five experiments support the argument that symmetry predication a is property of lexical items and has no special syntax; structural positioning of noun phrases in symmetricals-containing sentences sets their status as figure and ground or variant and referent, even for nonsensical nouns; and symmetrical predicate behavior varies as a function of…

Investigated the source of agrammatic aphasic patients' difficulty comprehending semantically reversible sentences. Found approximately equal distributions of three distinct patterns. Results conflict with explanations of comprehension failure which state that a single pattern of performance on sentence structures characterizes comprehension of…
