Resumo(s)
Spatial relations are considered as one of the most unique aspects of spatial or
geographical information and have linked the space and natural language. Many
spatial relations represent distance (topological relations) and directional relations.
This research discusses the role of topology for the conceptualization of different
movement and furthermore to assess the influence of two different scales of spaces
on cognitive classes through human subject tests. Two experiments are conducted
with two different scales. Each experiment was performed by 20 participants. Experiments
were fully based on the grouping paradigm. Grouping task enable to
categorize the movement entities into groups and establish the cognitive categories
or classes. Entities or movement patterns within a class are assumed to similar
to one another but different from the entities in other classes. It is believed that
the two scales of space are quite distinct in the ways people see and think about
them in their mind (Downs and Stea, 1977). To assess the influence of scale on the
cognitive classes, two different scales are assumed i. e bike and city and bike and
park. Similarity measure and category construction of different movement patterns
are assessed using both scales. All movement patterns were designed through conceptual
neighborhood graph. The result of this experiment shows that different
movement patterns are distinguished by the topological relations. This study not
also presents the importance of the topology for conceptualization and perception
of different movement patterns but also the influence of scale to distinguish the
different movement pattern and to build cognitive classes. The main finding of this
study is that the grouping behavior of Non- tangential proper part is found to be
different in both scales. Direction relations are also an important aspect of spatial
relations. Human beings use different angular information in their environment and
derive information. This study not also assesses the conceptualization of different
direction turns but also examine the category construction influenced by the two
different scales. This research discusses the category construction of direction turns
created in both scales. The results shows that human perceive different angular information and deduce this information. It is also examined that cognitive classes
constructed remain same in both scale. Furthermore, linguistic description is also
evaluated in this research but not in much detail. Verbal labeling of the groups
participant created also gives the idea about the human perception about the two
different scales.
