Meta-analysis was used to investigate the relationship between visuo-spatial ability and performance in remote environments. In order to be included, each study needed to examine the relationship between the use of an ego-centric perspective and various dimensions of performance (i.e., identification, localization, navigation, and mission completion time). The moderator analysis investigated relationships involving: (a) visuo-spatial construct with an emphasis on Carroll's (1993)...
Show moreMeta-analysis was used to investigate the relationship between visuo-spatial ability and performance in remote environments. In order to be included, each study needed to examine the relationship between the use of an ego-centric perspective and various dimensions of performance (i.e., identification, localization, navigation, and mission completion time). The moderator analysis investigated relationships involving: (a) visuo-spatial construct with an emphasis on Carroll's (1993) visualization (VZ) factor; (b) performance outcome (i.e., identification, localization, navigation, and mission completion time); (c) autonomy to support mission performance; (d) task type (i.e., navigation vs. reconnaissance); and (e) experimental testbed (i.e., physical vs. virtual environments). The process of searching and screening for published and unpublished analyses identified 81 works of interest that were found to represent 50 unique datasets. 518 effects were extracted from these datasets for analyses.Analyses of aggregated effects (Hunter (&) Schmidt, 2004) found that visuo-spatial abilities were significantly associated with each construct, such that effect sizes ranged from weak (r = .235) to moderately strong (r = .371). For meta-regression (Borenstein, Hedges, Figgins, (&) Rothstein, 2009; Kalaian (&) Raudenbush, 1996; Tabachnick (&) Fidell, 2007), moderation by visuo-spatial construct (i.e., focusing on visualization) was consistently supported for all outcomes. For at least one of the outcomes, support was found for moderation by test, the reliability coefficient of a test, autonomy (i.e. to support identification, localization, and navigation), testbed (i.e., physical vs. virtual environment), intended domain of application, and gender. These findings illustrate that majority of what researchers refer to as (")spatial ability(") actually uses measures that load onto Carroll's (1993) visualization (VZ) factor. The associations between this predictor and all performance outcomes were significant, but the significant variation across moderators highlight important issues for the design of unmanned systems and the external validity of findings across domains. For example, higher levels of autonomy for supporting navigation decreased the association between visualization (VZ) and performance. In contrast, higher levels of autonomy for supporting identification and localization increased the association between visualization (VZ) and performance. Furthermore, moderation by testbed, intended domain of application, and gender challenged the degree to which findings can be expected to generalize across domains and sets of participants.

This thesis explores the visibility of women in traditionally masculine Scottish national narratives as evidenced by their physical representation, or lack thereof, in the cultural heritage landscape. Beginning with the 1707 Act of Union between Scotland and England, a moment cemented in history, literature, and popular memory as the beginning of a Scottish rebirth, this thesis traces the evolution of Scottish national identity and the tropes employed for its assertion to paint a clearer...
Show moreThis thesis explores the visibility of women in traditionally masculine Scottish national narratives as evidenced by their physical representation, or lack thereof, in the cultural heritage landscape. Beginning with the 1707 Act of Union between Scotland and England, a moment cemented in history, literature, and popular memory as the beginning of a Scottish rebirth, this thesis traces the evolution of Scottish national identity and the tropes employed for its assertion to paint a clearer picture of the power of strategic selectivity and the effects of sacrifice in the process of community definition. Following the transformation of the rugged Celtic Highlander from his pre-Union relegation as an outer barbarian to his post-Union embrace as the epitome of distinction and the embodiment of anti-English, anti-aristocratic sentiment so crucial to the negotiation of a Scottish place in union and empire, this thesis hones in on notions of gender and peformative identity to form the basis for an analysis of twentieth and twenty-first century national heritage dynamics. An innovative spatial study of monuments and memorials in the Scottish capital city of Edinburgh highlights the gendered inequity of memorialization efforts and the impact of limited female visibility on the storytelling potential of the cityscape. Such a perspective not only adds a distinct visual component but also brings my study full circle by exemplifying contemporary discussions on the role of gender in narrative-setting, the sociocultural relevance of monuments and memorials, and the nature of representation in public spaces.
