Measurement and Application of Egoistic and Moralistic Self‐enhancement

Five studies were conducted to develop and validate the Egoistic and Moralistic Self‐enhancement (EMS) scale, a new self‐report measure of egoistic and moralistic self‐enhancement. Exploratory and confirmatory factor analysis provided evidence for a two‐factor structure comprising the tendencies to promote agentic (egoistic) and communal (moralistic) qualities (Study 1). Construct validity was supported by significant correlations with established measures of socially desirable responding, such as the Balanced Inventory of Desirable Responding (Study 2) and the Impression Management scale of the 16 Personality Factors (Study 3). When the EMS scale has been applied in organizational settings, we found that job applicants were more inclined than nonapplicants to promote their own agentic and communal qualities, although differences were more pronounced for egoistic self‐enhancement (Study 4). Findings also suggested that exaggeration of agentic qualities decrease the criterion‐related validity of conscientiousness in predicting job performance (Study 5). Taken together, findings suggest that the EMS scale provides a valid and reliable measure that can be fruitfully used for both theoretical and applied research.     

Disentangling trait from state components in the assessment of egoistic and moralistic self-enhancement

A latent state-trait model has been used to assess the extent to which egoistic and moralistic self-enhancement represent: (a) stable individual differences and (b) systematic effects of the situation and/or the person-situation interaction. Analyses were conducted on a sample of 187 adults (64% females). Findings revealed that both self-enhancement tendencies mostly capture stable interindividual differences, although significant occasion-specific effects were observed. Egoistic self-enhancement presents a higher proportion of trait variance than moralistic self-enhancement. The egoistic dimension was mostly related with the stable (trait) components of conscientiousness and emotional stability. The moralistic dimension, on the contrary, was mostly related with the transient component of emotional stability. Potential explanations for the observed differences between egoistic and moralistic self-enhancement were discussed and interpreted in terms of their implications for personality assessment.     

“So You Wanna Be a Pop Star?”: Schadenfreude Following Another's Misfortune on TV

In this experiment we demonstrate that low self-evaluation individuals experience more schadenfreude following an unfavorable performance of a contestant on a TV show after receiving negative feedback on a self-relevant task, as compared with those who received positive feedback. Moreover, we show that high self-evaluation individuals do not differ in their experience of schadenfreude as a function of feedback. These findings corroborate our argument that in a “double whammy” condition (i.e., low self-evaluation and induced self-threat), individuals will be more motivated to restore their self-worth and, consequently, experience more pleasure at the misfortunes of others.     

When the whole is more than the sum of its parts: Group motivation gains in the wild

Whereas negative effects of groups on individual motivation have been reported for many years, recent research has begun to show when and why working in a group can produce motivation gains compared to individual work. So far, this evidence has been limited to laboratory settings and rather simple tasks. Using data from swimming competitions at the 2008 Olympics, evidence is presented that motivation gains in groups also occur in field settings with more complex tasks. Based on an instrumentality × value approach, we expect that late positions in a relay trigger motivation gains in groups due to an increase in perceived indispensability for the group outcome. This idea has been initially tested in a pilot study with competitive swimmers, demonstrating that perceived indispensability for the relay outcome indeed increases with later serial positions in a relay. Moreover, the main study with data from the 2008 Olympics revealed performance times consistent with this pattern of indispensability perceptions: while starting swimmers in the swimming relays performed at similar levels as in their individual competitions, swimmers at the later positions showed higher performance in the relay compared to their individual competition heats.     

The organization and dissolution of semantic-conceptual knowledge: Is the ‘amodal hub’ the only plausible model?

In recent years, the anatomical and functional bases of conceptual activity have attracted a growing interest. In particular, Patterson and Lambon-Ralph have proposed the existence, in the anterior parts of the temporal lobes, of a mechanism (the 'amodal semantic hub') supporting the interactive activation of semantic representations in all modalities and for all semantic categories. The aim of then present paper is to discuss this model, arguing against the notion of an 'amodal' semantic hub, because we maintain, in agreement with the Damasio's construct of 'higher-order convergence zone', that a continuum exists between perceptual information and conceptual representations, whereas the 'amodal' account views perceptual informations only as a channel through which abstract semantic knowledge can be activated. According to our model, semantic organization can be better explained by two orthogonal higher-order convergence systems, concerning, on one hand, the right vs. left hemisphere and, on the other hand, the ventral vs. dorsal processing pathways. This model posits that conceptual representations may be mainly based upon perceptual activities in the right hemisphere and upon verbal mediation in the left side of the brain. It also assumes that conceptual knowledge based on the convergence of highly processed visual information with other perceptual data (and mainly concerning living categories) may be bilaterally represented in the anterior parts of the temporal lobes, whereas knowledge based on the integration of visual data with action schemata (namely knowledge of actions, body parts and artefacts) may be more represented in the left fronto-temporo-parietal areas.     

Time and defeasibility in FIPA ACL semantics

Inferences about speech acts are often conditional, non-monotonic, and involve the issue of time. Most agent communication languages, however, ignore these issues, due to the difficulty to combine them in a single formalism. This paper addresses such issues in defeasible logic, and shows how to express a semantics for ACLs in order to make non-monotonic inferences on the basis of speech acts.     

Motivation Gains in Computer‐Supported Groups1

One challenge in computer‐supported groups is the maintenance of high performance motivation of group members because face‐to‐face interaction and social control are restricted. Based on research on the Kohler effect (Hertel, Kerr, & Messe, 2000), we expected high motivation of group members when their individual effort is highly instrumental for the group's success. First, a task paradigm was developed and validated to measure motivation in a computer task. Then, this paradigm was used to explore group members’ motivation in computer‐supported dyads without face‐to‐face contact. Consistent with our expectations, motivation (and performance) of the group members was high and even exceeded the baseline of individual work (thus revealing motivation gains) when the individual's contribution was highly instrumental for the dyad's success (i.e., weaker coworker under conjunctive task demand). When instrumentality was low (i.e., weaker coworker under additive task demand), inconclusive results were obtained. Overall, the results demonstrate that motivation gains can be produced in computer‐supported dyads, even without face‐to‐face interaction.     

Vagueness-Adaptive Logic: A Pragmatical Approach to Sorites Paradoxes

Kripke-completeness of every classical modal logic with Sahlqvist formulas is one of the basic general results on completeness of classical modal logics. This paper shows a Sahlqvist theorem for modal logic over the relevant logic Bin terms of Routley-Meyer semantics. It is shown that usual Sahlqvist theorem for classical modal logics can be obtained as a special case of our theorem.     

The effects of presentation time on preference for curvature of real objects and meaningless novel patterns

Objects with curved contours are generally preferred to sharp‐angled ones. In this study, we aim to determine whether different presentation times influence this preference. We used images of real objects (experiment 1) and meaningless novel patterns (experiment 2). Participants had to select one of two images from a contour pair, curved and sharp‐angled versions of the same object/pattern. With real objects, the preference for curved versions was greatest when presented for 84 ms, and it faded when participants were given unlimited viewing time. Curved meaningless patterns were preferred when presented for 84 and 150 ms. However, in contrast to real objects, preference for meaningless patterns increased significantly in the unlimited viewing time condition. Participants discriminated poorly between the two versions (curved and sharp‐angled) of the meaningless patterns in the 84‐ and 150‐ms presentations (experiment 3). Therefore, in short times with meaningless patterns, participants selected mostly the curved version without being aware of the difference. In conclusion, presentation time, type of stimulus, and their interaction influence preference for curvature.
