The perception of concurrent sound objects in harmonic complexes impairs gap detection

Since the introduction of the concept of auditory scene analysis, there has been a paucity of work focusing on the theoretical explanation of how attention is allocated within a complex auditory scene. Here we examined signal detection in situations that promote either the fusion of tonal elements into a single sound object or the segregation of a mistuned element (i.e., harmonic) that "popped out" as a separate individuated auditory object and yielded the perception of concurrent sound objects. On each trial, participants indicated whether the incoming complex sound contained a brief gap or not. The gap (i.e., signal) was always inserted in the middle of one of the tonal elements. Our findings were consistent with an object-based account in which perception of two simultaneous auditory objects interfered with signal detection. This effect was observed for a wide range of gap durations and was greater when the mistuned harmonic was perceived as a separate object. These results suggest that attention may be initially shared among concurrent sound objects thereby reducing listeners' ability to process acoustic details belonging to a particular sound object. These findings provide new theoretical insight for our understanding of auditory attention and auditory scene analysis.     

Ideology,Fear of Death,and Death Anxiety

Ideological beliefs have long attracted the attention of social psychologists, who have investigated their genesis as well as their influence on a host of social phenomena. Conservatism, from the Motivated Social Cognition framework, stems from epistemic and existential needs of the individual, and notably the fear of death. However, Terror Management Theory proposes a view of conservatism and its contrary, liberalism, as equivalent cultural worldviews, equally fit to fulfill such needs. In the present contribution, results are presented from five studies, which test the contrasting hypotheses derived from these two perspectives. A new perspective is considered that accounts for these and previous findings.     

Self‐Awareness Part 1: Definition,Measures, Effects,Functions, and Antecedents

Self‐awareness represents the capacity of becoming the object of one’s own attention. In this state one actively identifies, processes, and stores information about the self. This paper surveys the self‐awareness literature by emphasizing definition issues, measurement techniques, effects and functions of self‐attention, and antecedents of self‐awareness. Key self‐related concepts (e.g., minimal, reflective consciousness) are distinguished from the central notion of self‐awareness. Reviewed measures include questionnaires, implicit tasks, and self‐recognition. Main effects and functions of self‐attention consist in self‐evaluation, escape from the self, amplification of one’s subjective experience, increased self‐knowledge, self‐regulation, and inferences about others’ mental states (Theory‐of‐Mind). A neurocognitive and socioecological model of self‐awareness is described in which the role of face‐to‐face interactions, reflected appraisals, mirrors, media, inner speech, imagery, autobiographical knowledge, and neurological structures is underlined.     

Opposition to Antiracism Laws Across Swiss Municipalities: A Multilevel Analysis

Public opposition to antiracism laws—an expression of prejudice toward immigrants—is widespread in Switzerland as well as in other European countries. Using data from the European Social Survey 2002 (N = 1,711), the present study examined across Swiss municipalities individual and contextual predictors of opposition to such laws and of two well‐established antecedents of prejudice: perceived threat and intergroup contact. The study extends multilevel research on immigration attitudes by investigating the role of the ideological climate prevailing in municipalities (conservative vs. progressive), in addition to structural features of municipalities. Controlling for individual‐level determinants, stronger opposition to antiracism laws was found in more conservative municipalities, while the proportion of immigrants was positively related to intergroup contact. Furthermore, in conservative municipalities with a low proportion of immigrants, fewer intergroup contacts were reported. In line with prior research, intergroup contact decreased prejudiced policy stances through a reduction of perceived threat. Overall, this study highlights the need to include normative and ideological features of local contexts in the analysis of public reactions toward immigrants.     

The Presence of Left-Wing Authoritarianism in Western Europe and Its Relationship with Conservative Ideology

The presence of left-wing authoritarianism (LWA) as well as its relationship with right-wing authoritarianism (RWA) and conservative ideology was tested in three Flemish samples. In the first study conducted on a sample of ordinary voters ( N =  208), a newly developed LWA scale was found to be internally consistent and to show high construct validity. In the second study, another voter sample ( N =  264) and a sample of political activists ( N =  69) were tested. In the two samples of ordinary voters, only a few people obtained high LWA scores. Moreover, the aggression and submission items did not load on distinct components and LWA was positively related to RWA and cultural conservatism and negatively to economic conservatism. Conversely, in the political activist sample high LWA scores were common among left-wing extremists and evidence was found for a two-dimensional LWA aggression-submission structure. LWA was negatively related to RWA, cultural conservatism, and economic conservatism. The concept of LWA and its theoretical underpinnings are discussed.     

Effect of social-class belonging on the cognitive dissonance resulting from threat severity

Results of two experiments using a ‘forbidden toy’ paradigm partially confirm those of a former study which showed an interaction between social-class level of the children and threat severity on the final rankings of the toy. Lower-class children derogated the forbidden toy more than middle-class children in the harsh threat condition. Opposed results were observed in the mild threat condition. Interpretation of such results seems difficult in terms of cognitive dissonance theory.     

Significance,structure, and gender differences in life domains of college students

The purpose of this study was to assess the significance and structure of life domains of college students and to explore the patterns of gender differences on different indices of significance. Four hundred fifty-seven college students rated 21 life domains in terms of degree of importance, frequency of involvement, and level of impact. They also responded to a measure of global life satisfaction. Gender differences on significance indices were investigated by means of three types of analyses. First, gender mean ratings on 21 life domains were compared via one-way multivariate analyses of variance. Second, the underlying dimensions of the 21 domains for each gender were compared via exploratory factor analyses. Third, the correlation patterns between perceived positive impact of each life domain and life satisfaction were calculated separately for men and women. Within-group comparisons revealed that men and women shared the same nine most significant domains: education, friends, biological needs, leisure, family, health, couple, esthetics, and physical activities. However, several gender differences were consistently found in the three types of analyses. The results indicated that although traditionally feminine domains are rated as more significant to women than men, traditional masculine domains were rated as equally significant by men and women. Domains considered sex role neutral (e.g., personal planning) were rated as more significant by women than men. In general, women appear to experience greater cognitive, affective, and behavioral aspects of significance in a wider spectrum of activities and as well perceive their general life satisfaction as deriving from a broader range of sources. Results also highlight the importance of assessing the degree of significance of life domains as an initial step in the development of multidimensional self-related constructs.Preparation of this paper was made possible through grants from the Social Sciences and Humanities Research Council of Canada, the Fonds pour la Formation des Chercheurs et l'Aide à la Recherche (FCAR-Québec) and the Université du Québec à Montréal.

Archimedean qualitative probabilities

Necessary and sufficient conditions for the existence of a probability measure agreeing with a weak order on an algebra of events are given. In the case of a countable algebra they consist of an extension of Kraft, Pratt, and Seidenberg's (1959. Annals of Mathematical Statistics, 38, 780–786) additivity condition through the requirement of an Archimedean property. In the case of a σ-algebra and a σ-additive agreeing probability, Villegas' (1964. Annals of Mathematical Statistics, 35, 1787–1796) monotone continuity condition, which becomes necessary, is merely added to them.
