Magnetoencephalography (MEG) measured subjects' brain responses during a lexical decision task. The words employed come from six frequency categories, which were defined in terms of a linear decrease in log-frequency. Although frequency effects in reaction-time are well-documented in studies of lexical access, a neural component whose latency predicts(More)
This study reports on functional morpheme (I, D, and C) production in the spontaneous speech of five pairs of children who have undergone hemispherectomy, matching each pair for etiology and age at symptom onset, surgery, and testing. Our results show that following left hemispherectomy (LH), children evidence a greater error rate in the use of functional(More)
This article presents a rationale and description of GCS, or Grammatical Coding System. GCS is a general-use grammatical coding system designed for research on the language of normal and language-impaired children or adults and is especially useful for studies in which a relatively large number of participants are involved. It implements recent theoretical(More)
This study reports the results of an investigation of subject properties in the spontaneous speech of 14 4-year old English speaking children with Specific Language Impairment (SLI) and two control groups (age and MLUm). It is shown that while the children with SLI perform much below their age-level with respect to grammatical properties of subjects(More)
Track structures of high-LET particles can be simulated by various linear approaches. The distribution of distances seems to be an important parameter in understanding the type of interactions which occur and the biological effects which these excitations and ionizations will create; therefore, the distance distributions of these simulated track structures(More)
