Nicotine taken by ad lib smoking or other routes of administration has been reported to shorten reaction time (RT) in many cognitive tasks. Most of these tasks have used visually presented stimuli and require a simple motor response such as a button press. The reliance on this type of RT task makes

Abstract
There is a debate about the extent to which the effect of prenatal smoking on infant health outcomes is causal. Poor outcomes could be attributable to mother characteristics, which are correlated with smoking. I examine the importance of selection on the effect of prenatal smoking by using three British cohorts where the mothers' knowledge about the harms of prenatal smoking varied substantially. I find that the effect of smoking on the probability of a low birth weight birth conditional on gestation is slightly more than twice as large in 2000 compared with 1958, implying that selection could explain as much as 50% of the current association between smoking and birth outcomes.

We estimate a structural model of individual smoking behaviour emphasizing the role of individual risk belief on smoking choices. Our model consists of five equations: two selection equations for initiation and cessation decisions, and three switching outcome regressions for nonsmokers, ex-smokers,

## Abstract Recent studies have demonstrated that stress may increase the fluctuating asymmetry of teeth and limbs in laboratory animals. The present study investigates the effects of heat on such parameters. Pregnant laboratory rats are exposed to temperatures of 33Β°C during gestation. Increases i
