Previous research has demonstrated electroencephalogram (EEG) changes in response to low-odor concentrations, resulting in near-chance detection. Such findings have been taken as evidence for olfaction without awareness. We replicated and extended previous work by examining EEG responses to water-water control, 0.0001, 0. 001, 0.01, and 1 ppm isoamyl acetate (IAA) in water paired with water only. Detection was above chance (>50%) for.001 and above, and alpha decreased only to those concentrations, suggesting that EEG changes corresponded to IAA awareness. However, when correct trial EEGs were compared to incorrect trial EEGs during.001 ppm, right posterior/central alpha decreased during incorrect trials and alpha decreased more globally (including frontal sites) during correct trials. These data may not reflect awareness or unawareness per se. Instead, results are discussed regarding activation of perceptual systems in the posterior region during incorrect trials and the activation of frontal action systems during a subset of correct trials. 相似文献

Values and Voting 总被引:2,自引:0,他引:2
We examined relations of the 10 types of values in Schwartz's (1992) theory of voting. Hypotheses were generated by relating the core motivations of each value type to the ideological messages conveyed by party policies and symbols. Eight parties that ran in the 1988 Israeli elections were arrayed by judges on three ideological dimensions: classical liberalism, economic egalitarianism, state and religion. Discriminant analyses yielded a function whose coefficients for value types corresponded to hypotheses for the state and religion dimension and ordered party supporters on this dimension. After dropping religious parties, another value-based function ordered party supporters on the classical liberalism dimension, as predicted. Both functions significantly improved the party classification of voters in a representative national sample (N=769). Economic egalitarianism, a nonsalient dimension in Israeli politics, was unrelated to values. Results suggest that all types of values may be politically relevant depending on context. 相似文献

The Structure and Dynamics of Worry: Theory, Measurement, and Cross-National Replications 总被引:1,自引:0,他引:1

This article presents a comprehensive conceptualization of the structure of worry and the relation of worry to mental health and well-being. It is assumed that worries have two facets, namely, the object of a worry (e.g., self, close others, society, the world) and the domain of a worry (the field of life with which it is concerned). The object of a worry is presumed to be more important than its domain in determining the impact of worries on mental health. Only worries concerned with self and close others (micro worries) are expected to be related to poor mental health, whereas worries about society or the entire world (macro worries) are expected to be positively related to mental health. An instrument is introduced to study worries in accordance with the proposed structure. Its validity is tested by two confirmatory techniques (similarity structure analysis and confirmatory factor analysis) in samples from Israel, West Germany, and (the former) East Germany. Worry scores are also related to five mental health indicators. Results show that across samples micro and macro worries can validly be distinguished. Micro worries are strongly related to poor mental health, whereas macro worries are unrelated to mental health or relate marginally to positive well-being. 相似文献
