Title Decrements in cognitive performance in metal inert gas welders exposed to aluminium
Bibliographic information Sep. 1999, Vol.56, No.9, p.632-639. Illus. 35 ref.
Abstract In most investigations, little is discovered of the effects of exposure to occupational toxins on cognitive function because many functions cooperate to produce the single performance scores typically reported from neuropsychological tests. To facilitate the interpretation of neuropsychological scores, the issue of occupational exposure to aluminium was examined with an approach intended to increase understanding of those cognitive processes that may be affected. The impairments found were circumscribed. When the neuropsychological tasks were scored to show some of the underlying theoretical cognitive structures, the results indicated that performance difficulties were mainly detected in tasks requiring working memory, particularly that relating to processing of visuospatial information. There was also evidence that such impairments are more readily found in time limited tasks involving visually presented material, in which effective visual scanning combined with control of working memory is demanded.
