    Abstract
    The ability to recall a spatial layout from multiple orientations – spatial flexibility – is a challenging cognitive process, especially when the global configuration cannot be viewed from a single vantage point, as spatial information must first be integrated before it can be flexibly recalled. The current study examined if experiencing the transition between multiple viewpoints enhances spatial flexibility for both non-integrated (Exp. 1) and integrated environments (Exp. 2), if the type of transition matters, and if action provides an additional advantage over passive visual flow. In Experiment 1, participants viewed an array of dollhouse furniture from four viewpoints that presented the global configuration from multiple orientations. In Experiment 2, the array was viewed piecemeal, from four viewpoints that presented the global configuration in partial chunks. The control condition presented the dollhouse as a series of static views, whereas in the remaining conditions, visual flow was continuous. Participants viewed the natural transition between viewpoints, and either passively experienced the transitions (i.e., by watching the dollhouse rotate or being rolled around it), or actively generated them (i.e., by rotating the dollhouse or walking around it). Across both experiments, continuous visual flow significantly enhanced spatial flexibility when paired with observer movement around the dollhouse, either active or passive. Furthermore, when participants had to integrate spatial information across discrete learning experiences (Exp. 2), active movement provided a significant advantage above passive experience. These findings suggest that array stability is key to flexible spatial memory, with action providing an additional boost to spatial integration.

      The Effects of Spatial Aggregation on Spatial Time Series Modeling and Forecasting

      Wei, William W. S.; Krafty, Robert T.; Dong, Yuexiao; Chervoneva, Inna (Temple University. Libraries, 2016)
      Spatio-temporal data analysis involves modeling a variable observed at different locations over time. A key component of space-time modeling is determining the spatial scale of the data. This dissertation addresses the following three questions: 1) How does spatial aggregation impact the properties of the variable and its model? 2) What spatial scale of the data produces more accurate forecasts of the aggregate variable? 3) What properties lead to the smallest information loss due to spatial aggregation? Answers to these questions involve a thorough examination of two common space-time models: the STARMA and GSTARMA models. These results are helpful to researchers seeking to understand the impact of spatial aggregation on temporal and spatial correlation as well as to modelers interested in determining a spatial scale for the data. Two data examples are included to illustrate the findings, and they concern states' annual labor force totals and monthly burglary counts for police districts in the city of Philadelphia.

      WHERE AM I? INDIVIDUAL DIFFERENCES IN MEMORY, NAVIGATION ABILITY, AND NAVIGATION STRATEGY

      Newcombe, Nora; Marchette, Steven A.; Chein, Jason M.; Gunderson, Elizabeth; Olson, Ingrid R.; Shipley, Thomas F. (Temple University. Libraries, 2014)
      Navigation proficiency - the ability to find and recall new and familiar locations - varies widely among individuals (e.g., Schinazi, Epstein, Nardi, Newcombe, & Shipley, 2013; Weisberg, Schinazi, Newcombe, Shipley, & Epstein, 2014). The cognitive processes that support effective navigation have been theoretically sketched out (e.g., Wolbers & Hegarty, 2010), but how do those processes contribute to aspects of and individual differences in navigation behavior? Using a virtual environment to assess navigation proficiency (Weisberg et al., 2014), we conducted two studies to investigate whether individual differences in navigating meaningfully relate to memory capacity (Study1) and navigation strategy (Study 2). Results from Study 1 suggest that working memory capacity may limit some participants' ability to build accurate cognitive maps. Using a virtual environment paradigm based on the rodent T-maze (Marchette, Bakker, & Shelton, 2011), Study 2 shows that good navigators do not prefer to use a place-based strategy over a response-based strategy, but there was an interaction between strategy selection and goals found. Good navigators who used a place-based strategy found more goals than good navigators who used a response-based strategy; the opposite was true for bad navigators. Emerging from this set of studies is a richer picture of how individual differences in cognitive traits (i.e., working memory capacity), and strategy choice relate to navigation proficiency.

      Spatial Regularization for Analysis of Text and Epidemiological Data

      Vucetic, Slobodan; Obradovic, Zoran; Vucetic, Slobodan; Dragut, Eduard Constantin; Henry, Kevin A. (Temple University. Libraries, 2022)
      Use of spatial data has become an important aspect of data analysis. Use of location information can provide useful insight into the dataset. Advancement of sensor technologies and improved data connectivity have made it possible to the generation of large amounts of passively generated user location data. Apart from passively generated data from users, explicit effort has been made by commercial vendors to curate large amounts of location related data such as residential histories from a variety of sources such as credit records, litigation data, driving license records etc. Such spatial data, when linked with other datasets can provide useful insights. In this dissertation, we show that spatial information of data enables us to derive useful insights in domains of text analysis and epidemiology. We investigated primarily two types of data having spatial information - text data with location information and disease related data having residential address information. We show that in the case of text data, spatial information helps us find spatially informative topics. In the case of epidemiological data, we show residential information can be used to identify high risk spatial regions. There are instances where a primary analysis is not sufficient to establish a statistically robust conclusion. For instance, in domains such as epidemiology, where a finding is not considered to be relevant unless some statistical significance is established. We proposed techniques for significant tests which can be applied to text analysis, topic modelling, and disease mapping tasks in order to establish significance of the findings.
