Component Models for Fuzzy Data

The fuzzy perspective in statistical analysis is first illustrated with reference to the “Informational Paradigm” allowing us to deal with different types of uncertainties related to the various informational ingredients (data, model, assumptions). The fuzzy empirical data are then introduced, referring to J LR fuzzy variables as observed on I observation units. Each observation is characterized by its center and its left and right spreads (LR₁ fuzzy number) or by its left and right “centers” and its left and right spreads (LR₂ fuzzy number). Two types of component models for LR₁ and LR₂ fuzzy data are proposed. The estimation of the parameters of these models is based on a Least Squares approach, exploiting an appropriately introduced distance measure for fuzzy data. A simulation study is carried out in order to assess the efficacy of the suggested models as compared with traditional Principal Component Analysis on the centers and with existing methods for fuzzy and interval valued data. An application to real fuzzy data is finally performed. We would like to express our gratitude to the Editor, the Associate Editor, and the Referees whose comments and suggestions improved significantly the quality of the paper.     

Implicit and Explicit Occupational Gender Stereotypes

This study was designed to compare implicit and explicit occupational gender stereotypes for three occupations (engineer, accountant, and elementary school teacher). These occupations represented the end points and middle of a masculine–feminine continuum of explicit occupational gender stereotypes. Implicit stereotypes were assessed using the Implicit Association Test (IAT), which is believed to minimize self-presentational biases common with explicit measures of occupational gender stereotypes. IAT results for the most gender stereotyped occupations, engineer (masculine) and elementary school teacher (feminine), were comparable to explicit ratings. There was less agreement with less stereotyped comparisons. Results indicated that accounting was implicitly perceived as more masculine than explicit measures indicate, which calls into question reports of diminishing gender stereotyping for such occupations.

Are members of low status groups perceived as bad, or badly off? Egalitarian negative associations and automatic prejudice

Three studies explored the hypothesis that implicit measures of prejudice can tap negative, yet egalitarian associations. In Study 1, automatically associating African Americans with oppression predicted greater automatic prejudice. In Studies 2 and 3, classically conditioning associations between the novel group Noffians and words like oppressed, maltreated, and victimized led to greater automatic prejudice against Noffians. Results suggest that White Americans’ negative automatic associations with African Americans may partly result from associating members of low status groups with unfair circumstances. Because automatic associations predict prejudiced behaviors, the burden of proof is on those wishing to argue that egalitarian negative associations complicate the assessment of automatic attitudes rather than contribute to prejudiced responses. Discussion focuses on the implications of egalitarian negative associations for the theory and measurement of automatic prejudice.     

What lies beneath: Parenting style and implicit self-esteem

The current studies extend previous research on self-esteem by examining one of the likely origins of implicit self-esteem. Three studies showed that young adult children who reported that their parents were more nurturing reported higher implicit self-esteem compared with those whose parents were less nurturing. Studies 2 and 3 added a measure of overprotectiveness and revealed that children who reported that their parents were overprotective also reported lower implicit self-esteem. Moreover, Study 3 revealed that mothers’ independent reports of their early interactions with their children were also related to children’s level of implicit self-esteem. In all three studies, these findings remained reliable when we controlled statistically for participants’ explicit self-esteem. These findings contribute to a growing body of literature validating the construct of implicit self-esteem.     

The influence of experimentally created extrapersonal associations on the Implicit Association Test

We examined the influence of extrapersonal associations (Olson & Fazio, 2004)—associations that neither form the basis of the attitude nor become activated automatically in response to the object—on the Implicit Association Test (Greenwald, McGhee, & Schwartz, 1998) by experimentally creating both attitudes and extrapersonal associations. The results revealed that participants who were given extrapersonal information that was inconsistent with their own attitudes were affected by this information when they later performed an IAT. They exhibited significantly reduced IAT scores compared to participants who were provided attitude-consistent extrapersonal information. This attenuation of the IAT effect occurred despite the fact that participants rated the source of the attitude-inconsistent extrapersonal information as irrational and foolish. On the other hand, the extrapersonal associations did not influence a subliminal priming measure in Experiment 1, nor a personalized version of the IAT (Olson & Fazio, 2004) in Experiment 2. These measures proved sensitive to the attitude, regardless of the congruency of the extrapersonal information.     

Stereotypes and implicit social comparison: Shifts in comparison-group focus

Stereotypes affect how people understand implicit comparisons. In two studies, people judged the comparison implied by a statement (e.g., “Math is easy for me,” “I’m really aggressive”) made by an African-American, White, or Asian-American male. Counter-stereotypic comments, such as the African-American saying he was “bad” at basketball, caused participants to think the target was comparing himself to his narrow ingroup; stereotypic statements caused people to infer that the comparison group was broader. When compared to a fixed standard (all people in USA), evidence that people used stereotypes consistently emerged. Whether motivated or not, by narrowing the comparison standard when presented with a counter-stereotypic case, participants constructed an understanding of the target that protected the stereotype from challenge.

Implicit but not explicit self-esteem predicts future depressive symptomatology

To date, research on the predictive validity of implicit self-esteem for depressive relapse is very sparse. In the present study, we assessed implicit self-esteem using the Name Letter Preference Task and explicit self-esteem using the Rosenberg self-esteem scale in a group of currently depressed patients, formerly depressed individuals, and never depressed controls. In addition, we examined the predictive validity of explicit, implicit, and the interaction of explicit and implicit self-esteem in predicting future symptoms of depression in formerly depressed individuals and never depressed controls. The results showed that currently depressed individuals reported a lower explicit self-esteem as compared to formerly depressed individuals and never depressed controls. In line with previous research, all groups showed a positive implicit self-esteem not different from each other. Furthermore, after controlling for initial depressive symptomatology, implicit but not explicit self-esteem significantly predicted depressive symptoms at six months follow-up. Although implicit self-esteem assessed with the Name Letter Preference Test was not different between formerly depressed individuals and never depressed controls, the findings suggest it is an interesting variable in the study of vulnerability for depression relapse.     

Processing focus structure and implicit prosody during reading: differential ERP effects

Several recent studies have shown that focus structural representations influence syntactic processing during reading, while other studies have shown that implicit prosody plays an important role in the understanding of written language. Up until now, the relationship between these two processes has been mostly disregarded. The present study disentangles the roles of focus structure and accent placement in reading by reporting event-related brain potential (ERP) data on the processing of contrastive ellipses. The results reveal a positive-going waveform (350-1300 ms) that correlates with focus structural processing and a negativity (450-650 ms) interpreted as the correlate of implicit prosodic processing. The results suggest that the assignment of focus as well as accent placement are obligatory processes during reading.
