A principal factor analysis was performed on variables derived from a neuropsychological battery administered to 100 healthy young adults (aged 17-41 yrs) to investigate the construct validity of the Continuous Recognition Memory test (CRM). It was hypothesized that CRM "hits" and "false alarms" would load on different factors. The factors that emerged in the analysis were labeled Verbal Ability, Divided Attention, Attention to Visual Detail, Visuomotor Integration and Planning, and Learning and Memory. As expected, CRM hits had a significant loading on the Learning and Memory factor. However, CRM false alarms did not have a significant loading on the Divided …


Neuropsychologic Function In Toddlers Exposed To Cocaine In Utero: A Preliminary Study, K. A. Espy, P. M. Kaufmann, M. L. Glisky Nov 1999

Patterns of neuropsychological performance on A-not-B, inhibition, motor, cognitive, language, and behavior tasks were examined in 34 toddlers--17 cocaine-exposed (CE) and 17 nonexposed (NE) controls. CE toddlers exhibited greater perseveration, less inhibition, poorer emotional regulation, and less task orientation relative to NE toddlers. Overall cognitive and language skills and motor impairment status were comparable among CE and NE toddlers. Differences in perseveration, emotional regulation, and task orientation between CE and NE toddlers remained significant after statistically controlling for overall cognitive skill. Prenatal cocaine exposure may impart selective vulnerability for deficits in executive function, inhibition, and emotional regulation in toddlers, perhaps …


Executive Functioning In Preschool Children: Performance On A-Not-B And Other Delayed Response Format Tasks, K. A. Espy, P. M. Kaufmann, M. D. Mcdiarmid, M. L. Glisky Nov 1999

Executive Functioning In Preschool Children: Performance On A-Not-B And Other Delayed Response Format Tasks, K. A. Espy, P. M. Kaufmann, M. D. Mcdiarmid, M. L. Glisky

The A-not-B (AB) task has been hypothesized to measure executive/frontal lobe function; however, the developmental and measurement characteristics of this task have not been investigated. The present study examined performance on AB and comparison tasks adapted from developmental and neuroscience literature in 117 1.9-5.5 yr old preschool children. Age significantly predicted performance on AB, Delayed Alternation, Spatial Reversal, Color Reversal, and Self-Control tasks. A 4-factor analytic model best fit task performance data. AB task indices loaded on 2 factors with measures from the Self-Control and Delayed Alternation tasks, respectively. AB indices did not load with those from the reversal tasks …

Attempts to relate what is currently known regarding the brain's involvement in language processing during the early years of life. The authors focus on the event related potential (ERP) as a means to study the neuroelectrical correlates of language in the brains of infants and children. After reviewing general information concerning ERPs and language, this presentation relates how neonatal ERP measures of phonetic discrimination predict later language and reading abilities.
