Perceiving one's nation: entitativity, agency and security in the international arena

The perception of groups as real entities rather than mere aggregates of individuals has important consequences on intergroup relations. Social psychological research, in fact, shows that it affects stereotyping, identification process, and intergroup bias. Previous research has also shown that group entitativity is not a positive or negative group attribute per se; rather, it depends on the context and the relationship between the perceiver and the group. While enhancing entitativity leads to worse expectations about the out‐group actions, high entitativity is a valued characteristic when associated with an ally or with the in‐group. Indeed, enhancing in‐group entitativity leads to stronger in‐group identification. The specific reasons for why this is the case, however, remain to be ascertained. What is good about in‐group entitativity? In the present contribution we propose that in‐group entitativity may lead to perceive the group as a real entity provided with intentions and capacity for planned actions, notably ensuring the safety of its members by protecting them against external threats. We report two correlational studies conducted with American citizens (Study 1) and Italian citizens (Study 2), showing that in‐group entitativity is associated with a higher level of identification, attribution of intentionality, and perceived security provided by the in‐group. These findings were replicated in a third study—conducted with a role‐play method on a fictitious scenario—in which entitativity was manipulated rather than measured. Study 3 also shows that artificially increasing the perception of in‐group entitativity enhances perceived safety in an international context and reduces the perception of threat from an out‐group. Findings are discussed in terms of possible implications for intergroup and international relations.     

The semantic red effect: Processing the word red undermines intellectual performance

Recent research has shown that a two second glimpse of color can have an important influence on affect, cognition, and behavior. The present research examined whether perceiving color is necessary to produce an effect on psychological functioning or whether the mere act of processing a color word might be sufficient. Specifically, four experiments tested the hypothesis that processing the word red undermines intellectual performance, much like actually perceiving the color red. Supportive data were obtained with three different types of subtle manipulation, with three different types of control words, and on two different types of IQ test performance. Worry, but not mood or general arousal, was shown to mediate the semantic red effect, which appears to take place outside of individuals’ awareness. The theoretical and practical implications of the results are discussed.     

What makes revenge sweet: Seeing the offender suffer or delivering a message?

The present article investigates the conditions under which vengeful episodes are satisfactory for the victim/avenger. Two hypotheses are tested simultaneously: (1) victims are satisfied if they see the offender suffer, even if this suffering was imposed by fate (“comparative suffering” hypothesis) and (2) victims are satisfied if the offender signals that he understands why revenge was imposed upon him (“understanding” hypothesis). A laboratory experiment is described in which the source of the offender’s suffering (revenge vs. fate) and the offender’s understanding for the cause of his suffering were varied. As an implicit measure of goal fulfillment, participants completed a lexical decision task that measured the relative accessibility of aggression-related words (compared to non-aggressive words). The results corroborate the understanding hypothesis: Participants showed higher levels of implicit goal fulfillment if they decided to take revenge and if the offender signaled understanding for the vengeful response. The findings are discussed with regard to the question what people hope to achieve when they take revenge.     

Visual and tactile action effects determine bimanual coordination performance

Effect-based models of motor control assign a crucial role to anticipated perceptual feedback in action planning. Two experiments were conducted to test the validity of this proposal for discrete bimanual key press responses. The results revealed that the normally observed performance advantage for the preparation of two responses with homologous rather than non-homologous fingers becomes inverted when homologous fingers produce non-identical visual effects, and non-homologous fingers produce identical visual effects. In the second experiment the finger homology effect was strongly reduced when homologous fingers produced non-identical tactile feedback. The results show that representations of to-be-produced visual and tactile action effects both contribute to action planning, though possibly to a varying degree. Implications of these results for effect-based models of motor control are considered.     

Does familiarity or conflict account for performance in the word-stem completion task? Evidence from behavioural and event-related-potential data

The conflict monitoring theory (CMT) assumes that word-stems associated with several completions should lead to crosstalk and conflict due to underdetermined responding situation (Botvinick et al. in Psychol Rev 108(3):624–652, 2001). In contrast, the Multiple-Read-Out-Model (MROM) of Jacobs and Grainger (J Exp Psychol 20(6): 1311–1334, 1994) predicts a high level of general lexical activity (GLA) for word-stems with many completions, indicating a higher stimulus familiarity because these stems are more probable to be read. We compared word-stems with several completions against word-stems with one possible completion while measuring response times and electrophysiological recordings. Slowest response times and a distinct FN400 component, which has previously been related to the concept of familiarity (Curran in Memory Cogn 28(6):923–938, 2000), were apparent for word-stems that could only be associated with a single response. These findings support the claims of the MROM. Furthermore, the lack of the N2-component for word-stems with several completions continues to challenge the EEG-extension of the CMT (Yeung et al. in Psychol Rev 111(4):2004).     

Factor Retention Using Machine Learning With Ordinal Data

Determining the number of factors in exploratory factor analysis is probably the most crucial decision when conducting the analysis as it clearly influences the meaningfulness of the results (i.e., factorial validity). A new method called the Factor Forest that combines data simulation and machine learning has been developed recently. This method based on simulated data reached very high accuracy for multivariate normal data, but it has not yet been tested with ordinal data. Hence, in this simulation study, we evaluated the Factor Forest with ordinal data based on different numbers of categories (2–6 categories) and compared it to common factor retention criteria. It showed higher overall accuracy for all types of ordinal data than all common factor retention criteria that were used for comparison (Parallel Analysis, Comparison Data, the Empirical Kaiser Criterion and the Kaiser Guttman Rule). The results indicate that the Factor Forest is applicable to ordinal data with at least five categories (typical scale in questionnaire research) in the majority of conditions and to binary or ordinal data based on items with less categories when the sample size is large.     

Is there a universal need for positive self-regard?

It is assumed that people seek positive self-regard; that is, they are motivated to possess, enhance, and maintain positive self-views. The cross-cultural generalizability of such motivations was addressed by examining Japanese culture. Anthropological, sociological, and psychological analyses revealed that many elements of Japanese culture are incongruent with such motivations. Moreover, the empirical literature provides scant evidence for a need for positive self-regard among Japanese and indicates that a self-critical focus is more characteristic of Japanese. It is argued that the need for self-regard must be culturally variant because the constructions of self and regard themselves differ across cultures. The need for positive self-regard, as it is currently conceptualized, is not a universal, but rather is rooted in significant aspects of North American culture. Conventional interpretations of positive self-regard are too narrow to encompass the Japanese experience.     

Individualism and Authoritarianism Shape Attitudes Toward Physician-Assisted Suicide1

We investigated the relation between value orientations and attitudes toward physician-assisted suicide (PAS) in 267 United States college students. We predicted that individualistic values, especially those having to do with control and self-determination, would lead to favorable attitudes toward PAS, and authoritarianism would lead to a rejection of PAS. A positive association between individualism and approval of PAS emerged which was moderated by attitude importance: People who did not endorse individualistic values did not have favorable opinions of PAS, regardless of how important the issue was to them. However, for individualists, PAS attitudes and attitude importance were positively related. Independent of individualism, authoritarianism was negatively related to PAS attitudes. Primarily for low authoritarianism, we found a correlation between attitude and attitude importance. The discussion focuses on the value-expressive function of death-related attitudes.     

Construct validity and personality correlates of the Strelau temperament inventory

Strelau's reinterpretation of Pavlov's concept of nervous system properties has gained increasing attention in Western personality research, both with regard to the psychometric properties of the Strelau Temperament Inventory (STI) and with regard to the interrelations between STI and Western personality dimensions. The present study investigated the construct validity of the Strength of Excitation scale by examining its relationship to experimental indices of strength of the nervous system. Secondly, data on the convergence between STI, EPQ, SSS IV, and trait anxiety measures are presented, using German translations of all the questionnaires. The results confirmed the correlation between strength of excitation and a reaction time based measure of strength of the nervous system. A factor analysis on the questionnaire scales identified two factors. Factor I (activity/stimulation seeking) consisted of extroversion, mobility, strength of excitation and the sensation seeking scales whereas Factor II (instability vs control) was composed of anxiety/neuroticism/ psychoticism and strength of excitation/strength of inhibition/social desirability. These findings agree with Eysenck's and Strelau's theoretical predictions regarding the interrelations of Pavlovian properties and Western personality dimensions.
