The work that is sent to this journal must be original, not published or sent to be published elsewhere; and if it is accepted for publication, authors will agree to transfer copyright to International Journal of Psychological Research. 

To give up copyright, the authors allow that, International Journal of Psychological Research, distribute the work more broadly, check for the reuse by others and take care of the necessary procedures for the registration and administration of copyright; at the same time, our editorial board represents the interests of the author and allows authors to re-use his work in various forms. In response to the above, authors transfer copyright to the journal, International Journal of Psychological Research. This transfer does not imply other rights which are not those of authorship (for example those that concern about patents). Likewise, preserves the authors rights to use the work integral or partially in lectures, books and courses, as well as make copies for educational purposes. Finally, the authors may use freely the tables and figures in its future work, wherever make explicit reference to the previous publication in International Journal of Psychological Research. The assignment of copyright includes both virtual rights and forms of the article to allow the editorial to disseminate the work in the manner which it deems appropriate. 

The editorial board reserves the right of amendments deemed necessary in the application of the rules of publication.

Resumen

Investigación previa ha sugerido que el surco intraparietal (IPS) respalda juicios de distancia social, con mayor actividad observada en respuesta a objetivos juzgados para estar más cerca de otros (Yamakawa, Kanai, Matsumura, & Naito, 2009). Entre otros estímulos, la actividad en el surco intraparietal parece ser receptiva a objetivos variando en estatus sociales (Chiao et al., 2009; Cloutier, Ambady, Meagher, & Gabrieli, 2012). El presente proyecto examinó las respuestas cerebrales durante juicios de estatus sociales auto-referenciales de objetivos variando tanto en estatus morales como financieros. Usando un diseño de resonancia magnética asociada a evento, los participantes observaron fotografías de rostros masculinos emparejadas con distintos niveles de estatus financieros o morales. Durante la tarea, se les pidió a los participantes identificar explícitamente el estatus de cada objetivo en relación al de ellos. Enfocándose en la actividad del surco intraparietal, los resultados de los análisis del cerebro entero y de regiones de interés revelaron una interacción entre los tipos y niveles de estatus sociales. Las implicaciones de estos resultados son discutidas con respecto a nuestro entendimiento actual del impacto del estatus social en los substratos neuronales de la percepción de las personas.
