Moreover, they may then be motivated to alter their attitudes. The current study tested this latter notion by having an experimenter discredit the plausibility of an external source after misattribution had presumably occurred. Sixty-four female undergraduates were given a pill described as having either unpleasant side effects or no side effects. Subjects (Ss) then were committed to write counter-attitudinal essays under high-choice conditions. Some Ss were then told that a mistake had been made, and that they had actually been given the other form of the pill. As predicted, Ss who had initially been led to believe that the pill had aversive side effects but were later told that it did not, manifested behaviour-consistent attitude change. Resume Les tenants de la theorie de la dissonance supposent que si Ton associe a tort une cognition dissonante a une source externe, on peut en venir a s'interroger sur la pertinence de l'association. De plus, on peut etre motive par la suite a modifier ses attitudes. On a verifie s'il en etait ainsi avec l'aide d'un experimentateur qui devait nier la plausibilite d'une source externe une fois que l'association erronee aurait ete etablie. On a donne a 64 etudiantes du premier cycle une pilule qui devait occasionner des effets secondaires desagreables ou n'en occasionner aucun. Les etudiantes devaient ensuite rediger des essais dont 1'orientation £tait contraire a leurs attitudes, mais a l'egard desquels elles avaient vraiment l'impression d'exercer leur libre arbitre. On a ensuite avis£ certaines d'entre elles qu'une erreur avait ete conimise et qu'elles avaient en fait re<;u l'autre type de pilule. Comme predit, les etudiantes a qui on avait d'abord laiss£ croire aux effets desagreables pour ensuite les informer du contraire ont manifeste un changement d'attitude conforme au comportement. Research stimulated by Festinger's (1957) cognitive dissonance theory has demonstrated that people who behave in a counter-attitudinal manner

To assess respiratory health of this occupational group, we conducted a cross-sectional study, including a self-administered health and work questionnaire, spirometry, and chest radiography among 464 male California rice farmers. Mean age ± SO was 48.3 ± 15.2 yr; mean duration of rice farming was 25.7 ± 14.3 yr. Prevalences for respiratory symptoms were: chronic bronchitis (6.3%), physician-diagnosed asthma (7.1%), and persistent wheeze (8.8%). Chronic cough was reported by 7.1% of respondents and was associated with reported hours per year burning rice stubble. Mean FEV1 and FVC were at expected values. FEV1 was inversely associated with years working in rice storage and use of heated rice dryers. Mean FEF25-75 was 93% of expected and was inversely associated with rice storage activities involving unheated rice driers. ILO profusion scores~1/0 for small irregular opacities were seen in 18 (10.1%) of 178 chest radiographs. Study findings suggest increased asthma prevalence among California rice farmers. Radiologic findings consistent with dust or fiber exposure were increased compared with those of the general population, although no associations with specific farming activities were identified.
