There still lacks preciseness about the nature of the connection between psycholinguistic variables and the core of conceptual meaning. This article explores the relation between Age of Acquisition (AoA), Imaginability, Semantic richness, Familiarity and Concreteness in the constitution of semantic core meaning. We used a key recognition task, designed with 120 concepts and their first 5 attributes, extracted from the Semantic Attributes Norms in Spanish. 300 students took part in a concept recognition task, where they were asked to recognize certain concepts through different triads of attributes. The most influential variables were AoA and Imaginability. These results are congruent with studies that suggest the AoA as the most appropriate variable to explain results in lexical decisions tasks.

This theoretical essay aims to review the conceptions of the subject of one of the theoretical political economy systems that have had the greatest influence up to the present. The father of liberalism (Adam Smith) sustained a theory of Cartesian subject (modern), i.e., a true rational and self-conscious sapiens sapiens. Through cognitive psychology, the Nobel Prize in economics Kahneman and Tversky have a new variant of homoeconomicus, enriched with contributions of experimental science, substantially changing that old conception of man as a rational being that marked almost all thought modern. Given these “recent reviews” theoretical-methodological, engendered in the light of the so-called science of the mind, is that it is essential to rethink old notions of subject that it served as the foundation to the economic and political system, mentioned before. To this end, it is proposed to carry out a theoretical-methodological synergy between two scientific disciplines: economics and psychology. This syncretism could provide the basis for a new integrative scientific discipline, which many theorists have called neuro-economics. That is why, in the present work intends to make an informed a criticism based of a current economic theories, with main emphasis on the psychological and anthropological assumptions. Finally, it try to re-think a new model of homo economicus, articulating the main assumptions of the current economy with some of the contributions of cognitive psychology, biology and cognitive neuroscience, which results in a new paradigm called integrative psycho-neuro-economics.

El modelo de la Muestra de la Información sostiene que la probabilidad de que cierta información sea mencionada en un grupo es mayor si se encuentra disponible en muchos miembros que en uno solo. La información compartida en la matriz de creencias preexistente a la interacción social, tiene mayor probabilidad de ser expresada, repetida y validada por consentimiento e influye en el producto grupal. Objetivos: cuantificar el impacto de la matriz de creencias compartidas en los procesos de negociación de significados y comprender cualitativamente este proceso. Sujetos: Participaron 225 estudiantes de Psicología de la Universidad Nacional de Mar del Plata consensuando sobre la relación significativa entre 9 conceptos académicos.El conocimiento previo compartido fue operativizado usando la Centralidad Sociocognitiva. El mapeo de las redes semánticas de los participantes, su inter influencia y evolución en las diferentes instancias de la negociación, el tratamiento analítico de comparación cuali y cuantitativa y su resolución gráfica, se realiza por medio de métodos especiales desarrollados sobre Análisis de Redes Sociales. Resultados: Las predicciones de influencia social entre pares y la visualización de la evolución de las redes semánticas de los participantes y los grupos, arrojan resultados robustos y sugerentes para su aplicación a diversos ámbitos de interacción social y comunicacional.
