Mirror neurons : physiological requirement for emotional empathy and social and moral behaviour of human and nonhuman primates
2018
Fil: Claramonte Sanz, Vicente. Universitat de València. Departament de Filosofia. Área de Lògica i Filosofia de la Ciència; España. Claramonte Sanz, V. (2018). Las neuronas espejo: presupuesto fisiológico de la empatía emocional y de las conductas sociales y morales en primates humanos y no humanos. Metatheoria, 8(2), 15-22. A partir de la evidencia científica y los análisis debidos a los estudios de investigadores como Rizzolatti, Sinigaglia, Galle-se, Goldman, Iacoboni, etc., este artículo argumenta que el vínculo entre neuronas espejo y empatía emocional resulta corroborado por los estudios de Neurociencia sobre la actividad perceptiva y las reacciones emocionales. En particular, con las…
No synergy needed: ecological constraints favor the evolution of eusociality.
2015
In eusocial species, some individuals sacrifice their own reproduction for the benefit of others. It has been argued that the evolution of sterile helpers in eusocial insects requires synergistic efficiency gains through cooperation that are uncommon in cooperatively breeding vertebrates and that this precludes a universal ecological explanation of social systems with alloparental care. In contrast, using a model that incorporates realistic ecological mechanisms of population regulation, we show here that constraints on independent breeding (through nest-site limitation and dispersal mortality) eliminate any need for synergistic efficiency gains: sterile helpers may evolve even if they are …
The many faces of human sociality: uncovering the distribution and stability of social preferences
2018
There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …
Altruisme et modèle métaphorique
1993
This article addresses the relationship between economics and biology from the specific methodological perspective of concept transfers. To understand in what way biological theories may prove useful for the study of economic problems, we define, with reference to the work of some philosophers of science, a methodological tool which we call the "metaphorical model". This instrument is then used to elucidate some aspects of Becker's model on altruism as well as the reasons why his analysis has not been considered in the end to be fully convincing or relevant.
What should i do and who's to blame?
2022
The COVID-19 crisis has had a major impact on youth. This study examined factors associated with youth’s attitudes towards their government’s response to the pandemic and their blaming of individuals from certain risk groups, ethnic backgrounds, and countries or regions. In a sample of 5,682 young adults (Mage = 22) from 14 countries, lower perceived burden due to COVID-19, more collectivistic and less individualistic values, and more empathy were associated with more positive attitudes towards the government and less blaming of individuals of certain groups. Youth’s social identification with others in the pandemic mediated these associations in the same direction, apart from the COVID-19 …
Oh sister, where art thou? Spatial population structure and the evolution of an altruistic defence trait.
2014
The evolution of parasite virulence and host defences is affected by population structure. This effect has been confirmed in studies focusing on large spatial scales, whereas the importance of local structure is not well understood. Slavemaking ants are social parasites that exploit workers of another species to rear their offspring. Enslaved workers of the host species Temnothorax longispinosus have been found to exhibit an effective post-enslavement defence behaviour: enslaved workers were observed killing a large proportion of the parasites’ offspring. As enslaved workers do not reproduce, they gain no direct fitness benefit from this ‘rebellion’ behaviour. However, there may be an indir…
Proximal Paradox
2000
In today's societies relationships between near relatives and friends appear to be somewhat paradoxical. Some accounts present them as the social ideal, exalting the solidarity and altruism represented by proximal relationships. By contrast, others point to the social dangers in such relationships when they are conducted in the public sphere. In order to grasp the coexistence of these opposite views, this article attempts to place proximal relationships in the explanatory context of a gift economy, a concept with a long history in anthropology and which has lately been the focus of interest of a significant group of social thinkers.
Hold up and intergenerational transmission of preferences
2004
This paper focuses on the formation, evolution and stability of the distribution of preferences in the population and its relationship with the investment and bargaining strategies in a simplified hold up problem. More precisely, in our model a population of infinitely-lived players (say, for example, firms) with homogeneous selfish or self-regarding preferences is pair-wise matched at each period with a population of an equal size of short-lived players (say, for example, workers) with heterogeneous preferences. Both types of player play a two-stage game. In the first stage, they decide separately but simultaneously whether to make a general or a relation-specific investment. The latter ty…
Determinants affecting consumers' attention to fish eco-labels in purchase decisions: a cross-country study
2022
PurposeThe purpose of this study was to investigate the role of consumer altruism and other socio-cultural factors in predicting how much attention consumers pay to seafood eco-labels.Design/methodology/approachThe empirical investigation was carried out by administering an online questionnaire to a sample of Italian and Spanish people from December 2019 to April 2020. After carrying out the principal component analysis procedure, the work made use of an ordinal logistic regression.FindingsBoth Italian and Spanish consumers with an altruistic attitude, who feel that food produced in a sustainable way can protect the environment and workers, appear more likely to take an eco-label into accou…
Get some respect – buy organic foods! When everyday consumer choices serve as prosocial status signaling
2020
Status considerations have recently been linked to prosocial behaviors. This research shows that even everyday consumer behaviors such as favoring organic foods serve as prosocial status signaling. Key ideas from the continuum model of consumer impression formation and the theories of costly signaling and symbolic consumption are synthetized to make sense of this phenomenon. Two web-surveys (Ns = 187, 259) and a field study (N = 336) following experimental designs are conducted. This approach allows the analysis of both the more and less conscious reactions of consumers. Study 1 shows that the image of consumers favoring organic product versions is marked by characteristics consistent with …
