La movilidad peatonal está siendo cada vez más importante por su vinculación con la idea de ciudades sostenibles. En este punto, es crucial entender las actitudes y percepciones que los peatones tienen respecto a caminar y respecto al entorno urbano. En el presente trabajo se lleva a cabo un análisis cuantitativo y global de los entornos de movilidad peatonal, basado en la información obtenida a través de una encuesta que incluye cuestiones agrupadas en diferentes áreas temáticas concernientes a la movilidad peatonal en la ciudad de Granada. Los resultados obtenidos ponen de manifiesto la actitud positiva de la población respecto a caminar, así como el hecho de que bulevares y calles comerciales son las tipologías de calle de mayor preferencia por parte de la población. Un enfoque integral, basado en la encuesta, permite enriquecer la planificación de la movilidad local considerando mejoras en los entornos peatonales.Abstract. Pedestrian mobility is becoming increasingly important because of its link with the idea of sustainable cities. At this point, it is crucial to understand the attitudes and perceptions that pedestrians have regarding walking and regarding the urban environment. In the present work a quantitative and global analysis of pedestrian mobility environments is carried out, based on the information obtained through a survey that includes issues grouped in different thematic areas concerning pedestrian mobility in the city of Granada. The results obtained show the positive attitude of the population with regard to walking, as well as the fact that boulevards and shopping streets are the most preferred types of street on _____________ 1

When we plan sequences of actions, we must hold some elements of the sequence in working memory (WM) while we execute others. Research shows that execution of an action can be delayed if it partly overlaps (vs. does not overlap) with another action plan maintained in WM (partial repetition cost). However, it is not known whether all features of the action maintained in WM interfere equally with current actions. Most serial models of memory and action assume that interference will be equal, because all action features in the sequence should be activated to an equal degree in parallel; others assume that action features earlier in the sequence will interfere more than those later in the sequence, because earlier features will be more active. Using a partial repetition paradigm, this study examined whether serial position of action features in action sequences maintained in WM have an influence on current actions. Two stimulus events occurred in a sequence, and participants planned and maintained an action sequence to the first event (action A) in WM while executing a speeded response to the second event (action B). Results showed delayed execution of action B when it matched the first feature in the action A sequence (partial repetition cost), but not when it matched the last feature. These findings suggest that serial order is represented in the action plan prior to response execution, consistent with models that assume that serial order is represented by a primacy gradient of parallel feature activation prior to action execution.
