归类不确定情景下特征推理的综合条件概率模型

用大学生被试,通过三个实验探讨在集中呈现类别成员样本信息的归类不确定情景下的特征推理。实验结果表明,单纯的归类确定性程度和靶类别靶特征的代表性并不直接影响被试的特征推理,而是预测特征相对于目标特征的综合条件概率直接影响被试的特征推理;特征推理不是基于类别中介的间接推理,而是基于特征关联综合条件概率的直接推理。实验结果支持作者提出的预测特征综合条件概率模型。     

Workers' self‐objectification and tendencies to conform to others

Recent research showed that workers' self‐objectification—their self‐perception as objects rather than human beings—leads to detrimental intrapersonal consequences. In the present research, we explored whether this phenomenon may also affect interpersonal relations, by increasing workers' tendencies to conform. In a correlational study, Italian workers who perceived their work as more objectifying self‐objectified more—self‐attributed less human mental states and self‐perceive as more instrument‐like than human‐like—and, in turn, were more inclined to conform with others. The second study experimentally confirmed this pattern, showing that British workers who recalled an objectifying (vs. a non‐objectifying) work experience self‐objectified more. Self‐perception as instrument‐like was associated, in turn, with an increased tendency to adapt to others' opinions. The implications for organizational and social psychology are discussed.     

Sex-specific variation in facial masculinity/femininity associated with autistic traits in the general population

Reports linking prenatal testosterone exposure to autistic traits and to a masculinized face structure have motivated research investigating whether autism is associated with facial masculinization. This association has been reported with greater consistency for females than for males, in studies comparing groups with high and low levels of autistic traits. In the present study, we conducted two experiments to examine facial masculinity/femininity in 151 neurotypical adults selected for either low, mid-range, or high levels of autistic traits. In the first experiment, their three-dimensional facial photographs were subjectively rated by 41 raters for masculinity/femininity and were objectively analysed. In the second experiment, we generated 6-face composite images, which were rated by another 36 raters. Across both experiments, findings were consistent for ratings of photographs and composite images. For females, a linear relationship was observed where femininity ratings decreased as a function of higher levels of autistic traits. For males, we found a U-shaped function where males with mid-range levels of traits were rated lowest on masculinity. Objective facial analyses revealed that higher levels of autistic traits were associated with less feminine facial structures in females and less masculine structures in males. These results suggest sex-specific relationships between autistic traits and facial masculinity/femininity.     

Territorial sense of community,ethnic prejudice and political orientation

This research focused on territorial sense of community and ethnic prejudice. In particular, we related these two constructs and investigated their relationship to individual characteristics (personal political orientation, contact with immigrants, etc.) and community‐level ones (such as ethnic composition and the political orientation of the local government). Two studies were conducted in four small towns in central and southern Italy. For each study, 160 people were contacted. The instruments used were a questionnaire, the Italian Sense of Community Scale and the Blatant Prejudice Scale. The results showed that territorial sense of community is not related to ethnic prejudice or to the ethnic heterogeneity of the territory. It was also found that people with right‐wing political sympathies revealed higher levels of prejudice than people with left‐wing sympathies. Finally, in a town with a stable and consolidated left‐wing orientation of the local government we found, when the influence of personal political orientation was controlled for, lower levels of prejudice than in a town with a right‐wing orientation.

Constrained Maneuvering: Rhetoric as a Rational Enterprise

This paper discusses some of the ways recent models have brought rhetoric into argumentation theory. In particular, it explores the rationale for and role of rhetoric in the strategic maneuvering project of pragma-dialectics and compares it with the author’s own implementation of rhetorical features. A case is made for considering the active ways audiences influence the strategies of arguers and for seeing the role of rhetoric in argumentation as both fundamental and reasonable on its own terms.     

The contextually controlled, feature-mediated classification of symbols

The classification of names of people or objects based on the features acquired by the names and the sorting instructions provided is a commonplace occurrence. For example, given the names Renoir, Pollock, James and Voltaire the average adult would be able to classify them differentially based on the instruction to classify them based on vocation or nationality. In general, such a repertoire reflects the reclassification of symbols (i.e, the names of individuals) in terms of contextual cues (instructions to sort by vocation or nationality) and the features acquired by the symbols (the specific nationalities and vocations). The present experiment studied this phenomenon with the use of arbitrary stimuli that did not have clear preexperimental associations. Two of 4 participants classified the symbols into different equivalence classes based on the prevailing contextual cues and the features that had been acquired by the symbols. Using an ABA reversal design we then demonstrated that 1 participant classified the symbols in accordance with the contextual cues and acquired features when present, but not in the absence of the contextual cues. A 3rd participant showed symbol classification that differed from that predicted by the procedures, and the 4th classified the symbols based on one set of features but not on context. These data describe one set of conditions that could account for the establishment of complex classification repertoires that occur in natural settings.     

A general Bayesian multilevel multidimensional IRT model for locally dependent data

Many item response theory (IRT) models take a multidimensional perspective to deal with sources that induce local item dependence (LID), with these models often making an orthogonal assumption about the dimensional structure of the data. One reason for this assumption is because of the indeterminacy issue in estimating the correlations among the dimensions in structures often specified to deal with sources of LID (e.g., bifactor and two-tier structures), and the assumption usually goes untested. Unfortunately, the mere fact that assessing these correlations is a challenge for some estimation methods does not mean that data seen in practice support such orthogonal structure. In this paper, a Bayesian multilevel multidimensional IRT model for locally dependent data is presented. This model can test whether item response data violate the orthogonal assumption that many IRT models make about the dimensional structure of the data when addressing sources of LID, and this test is carried out at the dimensional level while accounting for sampling clusters. Simulations show that the model presented is effective at carrying out this task. The utility of the model is also illustrated on an empirical data set.     

The influence of correlations between noncritical features and reinforcement on stimulus generalization

One strategy to program for generalization is to vary noncritical features in teaching exemplars, thereby avoiding noncritical features from being highly correlated with reinforcement and thus gaining faulty stimulus control. In the current translational evaluation, 2 groups of adults of typical development were taught to respond to arbitrary stimuli with experimenter‐defined critical and noncritical features in a matching‐to‐sample task. The teaching arrangement used for 1 group programmed for low correlation between noncritical features and reinforcement; the teaching arrangement used for the other group programmed for high correlation between noncritical features and reinforcement. Participants in the former group displayed (a) faster acquisition of matching, (b) less variability in correct responding, and (c) a decreased likelihood of faulty stimulus control developing during training. The results contribute towards advancing the study of stimulus control and developing an explicit technology of generalization to better serve consumers of the application of our science.     

Transition between alloy–element partitioned and non-partitioned growth of austenite from a ferrite and cementite mixture in a high-carbon low-alloy steel

The growth of austenite from a mixture of ferrite and cementite in low-alloy steels can be classified into three temperature ranges above the eutectoid temperature. In the first range, the austenite growth and cementite dissolution are controlled by alloy element diffusion from the beginning. In the second, they are controlled by carbon diffusion and switch to alloy element diffusion control at a later stage. In the third, the cementite dissolution, if the ferrite matrix has transformed to austenite upon heating, is controlled by carbon diffusion until completion. The transition temperatures between these ranges are evaluated in a quaternary alloy containing Mn and Cr by Thermo-calc and DICTRA simulation, and are in essential agreement with earlier experimental results. The proposed simple approach of calculating the transition temperatures may facilitate our understanding of austenitization kinetics and the design of heat treatment, for example, homogenization and soaking, of high-carbon steels.     

Islam as a new social actor in Italian cities: mosque controversies as sites of inclusion and separation

Most Muslim immigrants oscillate in the public sphere between three levels in the public sphere: the local, the national and the transnational. While the national and transnational levels continue to be marked by a strong degree of conflictuality, it is at the local level where new integration strategies are implemented and ‘social capital’ is acquired. The comparison between two similar debates over the construction of a mosque in the Italian cities of Bologna and Florence with opposite outcomes reveals the importance of the local dimension in the construction of a national Islam and the significance of appropriate participatory tools in the inclusion of Muslims in the local public sphere. In particular, the article highlights the link between the legitimacy of Islam in the fabric of the city and the degree of openness of the Islamic community. It also illustrates how overcoming the reluctance and fear of different actors can allow citizens to assimilate the idea of ‘a mosque in the city’ and not just of ‘a mosque for Muslims’. The article describes how the use of appropriate tools, particularly of participatory decision-making, has made it easier for marginalised or politically excluded individuals to take steps towards full citizenship and for the Muslim community to emerge as a legitimate social actor in the local public sphere.
