Gramática Espacial Urbana: la orientación espacial guiada por reglas verbales / Spatial and Urban Grammar: spatial orientation focuses on verbal rules

Resumen Objetivo: Analizar el papel que juegan las reglas en forma de instrucciones verbales y conducta no vocal sobre la manera como las personas se orientan en el espacio urbano. Método: Investigación descriptiva de tipo exploratoria. Se seleccionaron de manera aleatoria 75 personas, hombres y mujeres, mayores de edad y de diversas condiciones sociales, a quienes se les indagó mediante entrevistas informales en distintos puntos del espacio público de Bogotá por la manera de llegar a un destino específico. La información fue recogida por asistentes de investigación quienes se hacían pasar por transeúntes en busca de un lugar mientras grababan la conversación con el entrevistado. Las entrevistas fueron analizadas mediante el programa Atlas.ti. Resultados: Permiten agrupar las respuestas de los transeúntes a los lugares de destino en cinco categorías de reglas o instrucciones que dan las personas: instrucciones de secuencia geográfica, de secuencia de lugares, instrucciones para reconocimiento del lugar, instrucciones temporo-espaciales y no vocales. Conclusiones: Las personas estructuran su conocimiento del espacio urbano a partir de un sistema de categorías verbales que tienen que ver con el seguimiento de reglas, las cuales se reflejan en instrucciones y comunicación no vocal o gestual a manera de expresiones corporales. Se discuten las implicaciones del estudio en la identificación de reglas que configuran una gramática espacial en contraposición a los modelos cognoscitivos y las aproximaciones de las neurociencias, así como los alcances para la planeación urbana y la enseñanza de la ubicación especial.

Abstract Objective: This research study aims to examine the role of verbal instructions and non-vocal behavior, in order to explore the way people are oriented in urban space. Method: A descriptive and exploratory method was conducted. 75 adult people of different social strata, men and women, randomed selected were informaly interviewed about how to reach to a specific place, in different public places of Bogota. Research assistants who were in charge of data collecting, act as pedestrian recorded the conversation of the interviewee. Interviews were analyzed using Atlas.ti software. Results: Showed five categories of rules or instructions given by people whom were interviewed in relation with destinations, including the interpretation that could be made on non-vocal expressions. Conclusions: People structure their knowledge of urban space based on a system of verbal categories that have to do with the following of rules which are reflected in instructions and non-vocal or gestural communication in the form of corporal expressions. The implications of the study are discussed in the identification of rules that configure a spatial grammar, as opposed to cognitive models and neuroscience approaches, as well as the scope for urban planning and the teaching of special location.

Development and Validation of the Way-Finding Ability Scale for Middle-Aged and Older Adults

BACKGROUND AND PURPOSE: This study was performed to newly develop the Way-Finding Ability Scale (WFAS) for middle-aged and older adults and validate its clinical utility. METHODS: The participants for verifying construct validity included 324 adults aged from 45 to 79 years, and 22 normal old adults without way-finding deficit (WFD), 41 amnestic mild cognitive impairment (aMCI), and 35 patients with Parkinson's disease (PD-MCI) for verifying discriminant validity. All participants were administered the newly constructed 28-item WFAS. RESULTS: Exploratory factor analysis of the WFAS revealed a four-factor solution (sense of direction and inattention, spatial learning and memory, strategic ability, and cardinal direction). This four-factor structure was confirmed by confirmatory factor analysis. The discriminant validity was examined by administering the WFAS to normal older adults and two patient groups (aMCI & PD-MCI). The results showed that the total scores of two patient groups were lower than that of normal older adults. The patients with WFD had significantly lower total scores than those without WFD. Interestingly, the total scores of patients without WFD were significantly lower than those of normal older adults suggesting that the cognitive functions associated with way-finding ability (WFA) were partially impaired in aMCI and PD-MCI patients without apparent WFD. The patients with WFD had consistently lower scores in every four-factor than those without WFD. CONCLUSIONS: These results indicated that the WFAS assesses the WFD reliably as well as estimates the degree of decline in WFA.

Where is my car? examining wayfinding behavior in a parking lot

This article examines wayfinding behavior in an extended parking lot belonging to one of the largest shopping malls in Santiago, Chile. About 500 people were followed while going to the mall and returning from it, and their trajectories were mapped and analyzed. The results indicate that inbound paths were, in average, 10% shorter that outbound paths, and that people stopped three times more frequently when leaving the mall than when accessing it. It is argued that these results are in line with previous research on the subject, which stress the importance of environmental information in shaping people`s behavior.
