Traditionally, the medial temporal lobe has been considered a key brain region for spatial memory. Nevertheless, executive functions, such as working memory, also play an important role in complex behaviors, such as spatial navigation. Thus, the main goal of this study is to clarify the relationship between working memory capacity and spatial memory performance. Spatial memory was assessed using a virtual reality-based procedure, the Boxes Room task, and the visual working memory with the computer-based Change Localization Task. One hundred and twenty-three (n = 123) participants took part in this study. Analysis of Covariance (ANCOVA) revealed a statistically significant relationship between working memory capacity and spatial abilities. Thereafter, two subgroups n = 60, were formed according to their performance in the working memory task (1st and 4th quartiles, n = 30 each). Results demonstrate that participants with high working memory capacity committed fewer mistakes in the spatial task compared to the low working memory capacity group. Both groups improved their performance through repeated trials of the spatial task, thus showing that they could learn spatial layouts independent of their working memory capacity. In conclusion, these findings support that spatial memory performance is directly related to working memory skills. This could be relevant for spatial memory assessment in brain lesioned patients.

Abstract. Research in psychology and social neuroscience distinguishes between dispositional and situational empathy for the cognitive and affective aspects of empathy. Yet, the Pictorial Empathy Test (PET) is one of the few brief tests focusing on situational affective empathy. This paper describes the adaptation of PET in a two-stage process, consisting of instrument translation and exploratory analysis of the construct in a university student sample, followed by confirmatory factor analysis and psychometric validation in a general population sample (Study 1, N = 79 and Study 2, N = 580). Our results indicate that the Spanish PET version constitutes a single factor structure with high internal consistency as well as high construct stability across genders and across in-person and online test administration setups. We report satisfactory convergent, discriminant, and nomological validity of the Spanish PET, as reported for the original version, in addition to when explored across new dimensions, like the Interpersonal Reactivity Index or in relation to age and prosocial tendencies. Based on the above, we discuss delineation of the distinct components of emotional empathy as measured by the instrument. The work presented supports the use of the Spanish PET version as a brief screening tool for state affective (emotional) empathy.
