Long-term neurobehavioral health effects of methyl parathion exposure in children in Mississippi and Ohio.

Methyl parathion (MP), an organophosphate pesticide licensed only for agricultural uses, was sprayed illegally for pest control in Mississippi and Ohio residences. To evaluate the association between MP exposure and neurobehavioral development, we assessed children 6 years or younger at the time of the spraying and local comparison groups of unexposed children using the Pediatric Environmental Neurobehavioral Test Battery (PENTB). The PENTB is composed of informant-based procedures (parent interview and questionnaires) and performance-based procedures (neurobehavioral tests for children 4 years or older) that evaluate cognitive, motor, sensory, and affect domains essential to neurobehavioral assessment.

Methods of assessing neurobehavioral development in children exposed to methyl parathion in Mississippi and Ohio.

Methyl parathion (MP), an organophosphate pesticide, was sprayed illegally for pest control in U.S. residences and businesses in Mississippi and Ohio.

Laterality, word valence, and visual attention: a comparison of depressed and non-depressed individuals.

Thirteen depressed and 13 non-depressed college students attended to valence-loaded word pairs (euphoric/dysphoric, euphoric/neutral, and neutral/dysphoric) on a computer screen. Each pair was observed through a viewing box with a vertical partition, each word in a different visual field. As a prior-entry task (Titchener, 1908) the words were simultaneously replaced by colored bars.

Coping in real time: using Ecological Momentary Assessment techniques to assess coping with the urge to smoke.

Coping is important for success at smoking cessation, yet little is known about the natural history of coping with urges to smoke during a cessation attempt. In this study, Ecological Momentary Assessment (EMA) methods were used to gather real-time quantitative and qualitative data. For 3 consecutive days during their first 10 days of smoking cessation, 36 participants used tape recorders and palm-top computers to record details of 389 coping episodes, during which they employed 1,047 coping responses.

Selective approaches to basic neurobehavioral testing of children in environmental health studies.

To identify neurotoxic effects in children living near hazardous waste sites, the Agency for Toxic Substances and Disease Registry (ATSDR) has designed a basic Pediatric Environmental Neurobehavioral Test Battery (PENTB) for children 1 through 16 years of age. It emphasizes tests appropriate to the stages of a child's development. These stages were fundamental factors in selecting tests for the PENTB, which includes both informant- and performance-based assessment procedures.
