Lateral versus frontal ERP predictors of reading skill.

Neuropsychological factors that could account for good versus poor reading skills include hemispheric asymmetry for language, signal processing efficiency, hemisphericity, and frontally based control of attention. Using event-related potential (ERP) measures of these constructs, we find that only hemisphericity accounts for individual differences in reading skill among our 15-year-old good readers, while the frontally generated Contingent Negative Variation attentional ERP accounts for reading skill differences among the poor readers. While good readers show expected hemispheric ERP asymmetries and poor readers do not, this group difference does not account for the variation in reading skill. These data suggest that below some crucial threshold, reading disability is predicted by frontal attentional skill, whereas above this threshold, good reading is better predicted by hemisphericity.

Strategies for dealing with solar particle events in missions beyond the magnetosphere.

For long duration missions beyond the magnetosphere, the hazards posed by solar particle events (SPE) require the development of new strategies to minimize both the radiation dose and the effects. Potential strategies include the development of improved short-term forecasting of SPE through better observations and research, consideration of HZE particles in real-time forecasting and monitoring, improved knowledge of the biological effects of the particles involved in SPE, and the development of methods for combining SPE forecasts with temporary shielding and chemical countermeasures. Evaluation of present capabilities and the identification of areas of further research to achieve the necessary capabilities are discussed.
