Judgments of Personal and Environmental Risks of Consumer Products—Do they Differ?

Many psychometric studies have investigated judgments concerning personal risks from technologies, activities or consumer products, but only a few studies have included judgments of risk to the environment. Thus, little is known about this aspect of environmental risk perception, and whether it differs from personal risk perception. This study investigates risk judgments for 30 consumer products of various types such as herbal remedies, mobile telephones, genetically engineered drugs, or garden pesticides. A survey was conducted in two German cities: Leipzig and West Berlin. In total, 408 subjects evaluated the consumer products with regard to personal and environmental risk (and other risk-related aspects) and whether they would recommend the product to others. The findings show statistically significant differences between the mean values of perceived personal risk and environmental risk for most products. Despite these differences, the rank order of mean personal risk and environmental risk judgments for the products is quite similar. However, separate analyses for each product reveal that correlations between perceived personal and environmental risk vary strongly across products. Multiple regression analyses with personal and environmental risk judgments as predictors and product recommendation as criterion, run separately for each consumer product, show that it is mainly the judgment of perceived personal risk that explains product recommendation. Perceived risk to the environment adds little explanatory power. The study also explores differences in judgments of personal and environmental risk with regard to two sociodemographic variables: location (former East Germany vs. West Germany) and gender. Differences in both types of risk judgments are found with regard to location but not for gender.     

IDENTIFYING TREATMENT EFFECTS IN MULTI-CHANNEL MEASUREMENTS IN ELECTROENCEPHALOGRAPHIC STUDIES: MULTIVARIATE PERMUTATION TESTS AND MULTIPLE COMPARISONS

A versatile procedure is described comprising an application of statistical techniques to the analysis of the large, multi‐dimensional data arrays produced by electroencephalographic (EEG) measurements of human brain function. Previous analytical methods have been unable to identify objectively the precise times at which statistically significant experimental effects occur, owing to the large number of variables (electrodes) and small number of subjects, or have been restricted to two‐treatment experimental designs. Many time‐points are sampled in each experimental trial, making adjustment for multiple comparisons mandatory. Given the typically large number of comparisons and the clear dependence structure among time‐points, simple Bonferroni‐type adjustments are far too conservative. A three‐step approach is proposed: (i) summing univariate statistics across variables; (ii) using permutation tests for treatment effects at each time‐point; and (iii) adjusting for multiple comparisons using permutation distributions to control family‐wise error across the whole set of time‐points. Our approach provides an exact test of the individual hypotheses while asymptotically controlling family‐wise error in the strong sense, and can provide tests of interaction and main effects in factorial designs. An application to two experimental data sets from EEG studies is described, but the approach has application to the analysis of spatio‐temporal multivariate data gathered in many other contexts.

An emotion-based model of risk perception and stigma susceptibility: cognitive appraisals of emotion, affective reactivity, worldviews, and risk perceptions in the generation of technological stigma.

A study (N=198) was conducted to examine hypotheses derived from an emotion-based model of stigma responses to radiation sources. A model of stigma susceptibility is proposed in which affective reactions and cognitive worldviews activate predispositions to appraise and experience events in systematic ways that result in the generation of negative emotion, risk perceptions, and stigma responses. Results of structural equation modeling supported the hypotheses. Radiation sources that scored higher on a measure of stigma were included in the analyses (i.e., nuclear power plants, radioactive waste from nuclear power plants, radiation from nuclear weapons testing). Individual differences in negative reactivity and worldviews were associated with the strength of emotional appraisals that were associated, in turn, with negative emotion toward stigmatized radiation sources. As hypothesized, the model fit better with perceived risk as a function of negative emotion rather than vice versa. Finally, a measure of stigma was associated with negative emotion and, to a lesser extent, with risk perceptions. Risk communication about stigmatized objects may benefit from a more complete understanding of how affective and emotional reactions are constructed and the routes through which they affect responses and behaviors.
