Prepulse inhibition (PPI) is an acoustic startle paradigm that has been used as an operational measure of sensorimotor gating. Many patients with schizophrenia have impaired PPI, and several lines of evidence suggest that PPI may represent a heritable endophenotype in this disease. We examined startle magnitude and latencies in 40 schizophrenia patients, 58(More)

These practices are usually performed by a nonmedical practitioner in the home or(More)
Measures of acoustic startle such as prepulse inhibition (PPI) and startle latency have been found to be impaired in schizophrenia, and are commonly thought to be related to cognitive deficits in this disease. However, findings about the relationship between startle variables and cognitive performance have been equivocal. In this study, we examined(More)
This study was conducted to evaluate the effectiveness of an experimental articulation testing instrument for differentiating child speakers of African-American Vernacular English (AAVE) with atypical and typical phonologies. Twenty-six AAVE-speaking children between the ages of 5:0 and 6:6 participated in the study. Based on their phonological skills in(More)
The Wisconsin Card Sorting Test (WCST) is a set-switching task used extensively to study impaired executive functioning in schizophrenia. Declarative memory deficits have also been associated with schizophrenia and may affect WCST performance because continued correct responding depends on remembering the outcome of previous responses. This study examined(More)
