Two studies of authoritarianism and environmental attitudes were under-taken. The first, a field study, found the opponents of a proposed riverside power plant to be less authoritarian and more environmentally concerned than supporters of the plants establishment. Overall, right-wing authoritarianism (RWA) correlated -.51 with environmental concern. The second study replicated this finding within a college sample, using a validated measure of environmental concern, the New Environmental Paradigm (NEP) scale. NEP correlated -.54 with RWA. It is concluded that the relationship between authoritarianism and environmental concern is presently strong. Prospective explanations for this relationship revolve around the theoretical nature of authoritarianism.

The relationship between MRI findings (i.e., subcortical hyperintensities; SH, whole brain volume) and the cognitive dysfunction of vascular dementia (VaD) was examined. Participants included 24 persons that met NINDS-AIREN criteria for VaD (MMSE = 19.9 ± 4.2) and underwent comprehensive neuropsychological assessment and MRI brain imaging. The volume of subcortical hyperintensities (SH) was strongly associated with executive–psychomotor performance, but not with performance across other cognitive domains or global cognitive functional level. Conversely, WBV was strongly associated with global cognitive functioning and performance across most cognitive domains (memory, language, visual integration), but not with executive–psychomotor functioning. The failure of SH to account for either the global dementia evident in these VaD patients or impairments across most cognitive domains suggests that deep subcortical white matter disease may only indirectly contribute to the global cognitive dysfunction of VaD. That WBV emerged as a stronger correlate of dementia raises further questions regarding the cerebral mechanisms that contribute to the development of VaD. (JINS, 2002, 8, 743–752.)
