Explaining the behaviour of random ecological networks: the stability of the microbiome as a case of integrative pluralism

Synthese - Explaining the behaviour of ecosystems is one of the key challenges for the biological sciences. Since 2000, new-mechanism has been the main model to account for the nature of scientific...     

Prediction and Cross-Situational Consistency of Daily Behavior across Cultures: Testing Trait and Cultural Psychology Perspectives

Trait and cultural psychology perspectives on the cross-situational consistency of behavior, and the predictive validity of traits, were tested in a daily process study in the United States (N = 68), an individualistic culture, and the Philippines (N = 80), a collectivistic culture. Participants completed the Revised NEO Personality Inventory (Costa & McCrae, 1992) and a measure of self-monitoring, then reported their daily behaviors and associated situational contexts for approximately 30 days. Consistent with trait perspectives, the Big Five traits predicted daily behaviors in both cultures, and relative (interindividual) consistency was observed across many, although not all, situational contexts. The frequency of various Big Five behaviors varied across relevant situational contexts in both cultures and, consistent with cultural psychology perspectives, there was a tendency for Filipinos to exhibit greater situational variability than Americans. Self-monitoring showed some ability to account for individual differences in situational variability in the American sample, but not the Filipino sample.     

Is perceived emotional support beneficial? Well-being and health in independent and interdependent cultures

Previous studies show there is little or no association between perceived emotional support and well-being in European American culture. The authors hypothesized that this paradoxical absence of any benefit of perceived support is unique to cultural contexts that privilege independence rather than interdependence of the self. Study 1 tested college students and found, as predicted, that among Euro-Americans a positive effect of perceived emotional support on subjective well-being (positive affect) was weak and, moreover, it disappeared entirely once self-esteem was statistically controlled. In contrast, among Asians in Asia (Japanese and Filipinos) perceived emotional support positively predicted subjective well-being even after self-esteem was controlled. Study 2 extended Study 1 by testing both Japanese and American adults in midlife with respect to multiple indicators of well-being and physical health. Overall, the evidence underscores the central significance of culture as a moderator of the effectiveness of perceived emotional support.     

Lexical studies of Filipino person descriptors: adding personality‐relevant social and physical attributes

Lexical studies have focused on traits. In the Filipino language, we investigated whether additional dimensions can be identified when personality‐relevant terms for social roles, statuses and effects, plus physical attributes, are included. Filipino students (N = 496) rated themselves on 268 such terms, plus 253 markers of trait and evaluative dimensions. We identified 10 dimensions of social and physical attributes—Prominence, Uselessness, Attractiveness, Respectability, Uniqueness, Destructiveness, Presentableness, Strength, Dangerousness and Charisma. Most of these dimensions did not correspond in a one‐to‐one manner to Filipino or alternative trait models (Big Five, HEXACO, ML7). However, considerable redundancy was observed between the social and physical attribute dimensions and trait and evaluative dimensions. Thus, social and physical attributes communicate information about personality traits, and vice versa. Copyright © 2008 John Wiley & Sons, Ltd.     

Long-term memory for performed and observed actions: retrieval awareness and source monitoring

The self-performed task (SPT) paradigm was employed to investigate incidental memory for action events, focusing on states of awareness at retrieval (Remembering-Knowing) and source monitoring in performed and observed actions, at delays of 1 and 2 weeks. Recognition was better for performed than observed actions, but this effect was visible only after 1 week of retention. Conversely, observed actions were associated with better source memory at both delays. When the source was correctly identified, performed and observed actions were accompanied by equal proportions of Remember judgements. However, when source monitoring was incorrect, performed actions were more frequently associated with a feeling of re-experiencing the original event, thus suggesting an enactment-related recollective superiority, although secondary to the availability of reliable contextual information.     

Qualitative differences in the representation of abstract versus concrete words: Evidence from the visual-world paradigm

In the present visual-world experiment, participants were presented with visual displays that included a target item that was a semantic associate of an abstract or a concrete word. This manipulation allowed us to test a basic prediction derived from the qualitatively different representational framework that supports the view of different organizational principles for concrete and abstract words in semantic memory. Our results confirm the assumption of a primary organizational principle based on association for abstract words, different from the semantic similarity principle proposed for concrete words, and provide the first piece of evidence in support of this view obtained from healthy participants. The results shed light on the representational structure of abstract and concrete concepts.     

Six Factors Fostering Protest: Predicting Participation in Locally Unwanted Land Uses Movements

In two studies we analyzed the predictors of participation in an Italian Lulu mobilization, rooted in the Susa Valley, a North-Western Italian valley where a high speed railway (HSR) should be sited. Based on the data of qualitative Study 1, performed interviewing 12 anti-HSR militants and 12 non anti-HSR militants, we hypothesized that Klandermans' (1997) model on participation (centered on group identification, sense of injustice, and collective efficacy) is suitable to predict the Lulu mobilization we studied, and that three contextual variables (community involvement, the perception of the existence of a vast majority in the community favoring the mobilization, and place attachment) may be added to Klandermans' to predict such a mobilization. We formally tested such hypotheses in quantitative Study 2 (representative sample of the people living in the Susa Valley, N =  250). Results supported the role of Klandermans' (1997) variables and confirmed the influence exerted by our contextual variables, thus suggesting that an integration of the two models would be fruitful in the analysis of Lulu mobilizations. Limits and future developments of this research are discussed.     

A question of intention in motor imagery

We examined the question—is the intention of completing a simulated motor action the same as the intention used in processing overt actions? Participants used motor imagery to estimate distance reachability in two conditions: Imagery-Only (IO) and Imagery-Execution (IE). With IO (red target) only a verbal estimate using imagery was given. With IE (green target) participants knew that they would actually reach after giving a verbal estimate and be judged on accuracy. After measuring actual maximum reach, used for the comparison, imagery targets were randomly presented across peripersonal- (within reach) and extrapersonal (beyond reach) space. Results indicated no difference in overall accuracy by condition, however, there was a significant distinction by space; participants were more accurate in peripersonal space. Although more research is needed, these findings support an increasing body of evidence suggesting that the neurocognitive processes (in this case, intention) driving motor imagery and overt actions are similar.
