Objetivos / Objectives
Ubicarnos óptimamente en el espacio es fundamental para la vida diaria. Para ello, empleamos dos
estrategias de orientación: egocéntrica (utiliza la posición del propio cuerpo como referencia) y
alocéntrica (emplea claves del entorno, dependiente del hipocampo). Estas son moduladas por la
memoria de trabajo, pero la influencia de la capacidad de percepción temporal y su relación con ellas
aún requiere mayor investigación. Por ello, el objetivo de este trabajo es comprobar las diferencias de
rendimiento según estrategia espacial (alocéntrica/egocéntrica), mediado por la memoria de trabajo y la
percepción temporal simultáneamente.
Metodología / Methodology
Un total de 20 hombres y 21 mujeres, todos ellos estudiantes de la Universidad de la Sapienza, fueron
evaluados empleando dos tareas virtuales de reconocimiento espacial (alocéntrica 3D y egocéntrica
2D). Ambas tareas contaron con dos tiempos de presentación diferentes para la imagen de muestra
(3000/1000ms) para verificar su influencia en el rendimiento. También se emplearon otras dos tareas
adicionales de memoria de trabajo y percepción temporal.
Resultados y Conclusiones / Results & Conclusions
Considerando memoria de trabajo y percepción temporal como covariables, en la tarea alocéntrica se
encontró que los hombres tienen mejor rendimiento respecto a las mujeres, modulado por el tipo de
ensayo (aciertos, falsas alarmas...). Por el contrario, en la tarea egocéntrica, no había diferencias en el
rendimiento entre hombres y mujeres, pero sí entre cada tipo de ensayo. En líneas generales, se refleja
una modulación diferencial de memoria de trabajo y percepción temporal para cada estrategia espacial.
Específicamente, solo se encuentra un patrón conductual sexualmente dimórfico para la estrategia de
orientación alocéntrica. Castillo Escamilla, Joaquín; Mirino, Pierandrea; Del Mar Salvador Viñas, María; María Carmona Lorente, Isabel; Manuel Cimadevilla Redondo, José; Guariglia, Cecilia - 04f Poster

The hippocampus is responsible for encoding both spatial and temporal aspects of information. Given
that the hippocampus is dimorphic between the sexes, it might stand to reason that if there are
differences in spatial ability, there are also differences in temporal ability, but there isn't much
evidence to explore this. In both abilities it has been possible to verify that in different tasks there are
significant differences in performance according to the age and sex of the participants. For this reason,
the objective of this study was to verify whether dimorphism occurs according to biological sex in
temporal perception tasks. For this, 55 participants were evaluated, of whom 25 were men and 30
women, all of them students at the University of Almería. This evaluation consisted of carrying out two
tests of temporal perception similar to each other in the programming. They were presented with an
object (in one task a car and in the other a square) that passed from the left to the right of the screen,
having a different speed on each trial. In the center appeared a rectangle that caused the object to
disappear for a variable time. The participants had to decide if the speed of the object was higher or
lower in the invisible part when compared to the visible part. The results showed that there were
differences between men and women in both tests, with men making fewer errors. This seems to be
in line with the results found in the evaluation of spatial ability, which could indicate that there are
apparently differences in the hippocampus between men and women. Another reason why these
differences could appear is the use of strategies, both for spatial and temporal skills, different between
both sexes. Future works can extend this evidence through the use of electroencephalography (EEG). Del Mar Salvador Viñas, María; Castillo Escamillar, Joaquín; María Carmona Lorente, Isabel; Pepe, Sofia; Mirino, Pierandrea; Manuel Cimadevilla Redondo, José - 04f Poster
