Tracing a Route and Finding a Shortcut: The Working Memory, Motivational, and Personality Factors Involved

Wayfinding (WF) is the ability to move around efficiently and find the way from a starting point to a destination. It is a component of spatial navigation, a coordinate and goal-directed movement of one\u2019s self through the environment. In the present study, the relationship between WF tasks (route tracing and shortcut finding) and individual factors were explored with the hypothesis that WF tasks would be predicted by different types of cognitive, affective, motivational variables, and personality factors. A group of 116 university students (88 F.) were conducted along a route in a virtual environment and then asked first to trace the same route again, and then to find a shortcut between the start and end points. Several instruments assessing visuospatial working memory, mental rotation ability, self-efficacy, spatial anxiety, positive attitude to exploring, and personality traits were administered. The results showed that a latent spatial ability factor (measured with the visuospatial working memory and mental rotations tests) \u2013 controlled for gender \u2013 predicted route-tracing performance, while self-report measures of anxiety, efficacy, and pleasure in exploring, and some personality traits were more likely to predict shortcut-finding performance. We concluded that both personality and cognitive abilities affect WF performance, but differently, depending on the requirements of the task

Residential Place Attachment as an Adaptive Strategy for Coping With the Reduction of Spatial Abilities in Old Age

This study intended to test whether attachment to one\u2019s own residential place at neighborhood level could represent a coping response for the elderly (consistently with the \u201cdocility hypothesis;\u201d Lawton, 1982), when dealing with the demands of unfamiliar environments, in order to balance their reduction of spatial abilities. Specifically, a sequential path was tested, in which neighborhood attachment was expected to play a buffer role between lowered spatial competence and neighborhood satisfaction. The participants (N D 264), senior citizens (over 65-year-old), responded to a questionnaire including the measures of spatial self-efficacy, spatial anxiety, attitude toward wayfinding, residential attachment and residential satisfaction. Results from the mediation analysis showed that a lower perceived spatial self-efficacy is associated to a higher spatial anxiety, and both promote a more negative attitude toward wayfinding tasks in non-familiar places. This leads to a higher attachment to one\u2019s own neighborhood, which in turn predicts a higher residential satisfaction. Thus, the \u201cclosure\u201d response of becoming more attached to their residential place may be an adaptive strategy of the elderly for compensating the Person-Environment (P-E) mis-fit (Lawton and Nahemow, 1973) when they feel unable (or less able) to cope with the demands of unfamiliar environments

Unexpected and just missed : the separate influence of the appraisals of expectancy and proximity on negative emotions

Previous research has suggested that a goal-incongruent outcome leads to more intense negative emotions when it is unexpected and close to a goal-congruent outcome. Until now, however, no studies have disentangled the influence of the appraisals of expectancy and proximity on emotions. We experimentally manipulated each of these variables in 3 slot machine experiments and measured emotions via differences in motivation (i.e., the tendency to repair the goal incongruence) and feelings (i.e., disappointment, frustration, and anger). The experiments consisted of a series of trials that each started with the sequential presentation of 3 symbols. In case of a win trial, all symbols were equal (e. g., AAA) and the participant gained 10 cents; in case of a loss trial, one or more of the symbols differed and the participant gained 0 cents. Three different loss trials were compared: unexpected proximal ones (e. g., AAB), expected proximal ones (e. g., ABA), and expected distal ones (e. g., ABC). The tendency to repair was measured online via behavior as well as retrospectively via self-reports; feelings were measured retrospectively (Experiments 1 and 2) or online (Experiment 3). Unexpected losses seemed to increase the tendency to repair as well as feelings of disappointment (in all experiments) and feelings of frustration and anger (in Experiments 1 and 3). Proximal losses increased only the tendency to repair (in all experiments). This suggests that the appraisals of expectancy and proximity have a distinct influence on emotions

Proceedings of KogWis 2012. 11th Biannual Conference of the German Cognitive Science Society

The German cognitive science conference is an interdisciplinary event where researchers from different disciplines -- mainly from artificial intelligence, cognitive psychology, linguistics, neuroscience, philosophy of mind, and anthropology -- and application areas -- such as eduction, clinical psychology, and human-machine interaction -- bring together different theoretical and methodological perspectives to study the mind. The 11th Biannual Conference of the German Cognitive Science Society took place from September 30 to October 3 2012 at Otto-Friedrich-Universität in Bamberg. The proceedings cover all contributions to this conference, that is, five invited talks, seven invited symposia and two symposia, a satellite symposium, a doctoral symposium, three tutorials, 46 abstracts of talks and 23 poster abstracts

Remote Airport Traffic Control Center (2008 - 2012) Final Presentation and Workshop - Extended Abstracts

The present report contains the extended and revised version of the abstracts collection of the presentations given at the final international workshop of the DLR-project RAiCe (Remote Airport traffic Control Center, 2008 - 2012), held on November 30 2012 in Braunschweig. The RaiCe presentations are complemented by two external contributions,from the Swedish ANSP LFV and company Frequentis, representing the industrial perspective on Remote Tower research and development. The RaiCe workshop was a satellite event of the Second SESAR Innovation Days (SID 2012, Nov. 27-29) which was held in Braunschweig, following the first one in Toulouse 2011. One of the RaiCe validation results papers was presented at SID2012 and is also included in the present report for com-pleteness, besides inclusion in the SID2012 proceedings. In addition to the collection of extended abstracts and an introduction, besides some general refer-ences a list of the publications of the DLR Remote Tower Group (time frame 2002 – 2012) is provid-ed. A list of the workshop participants is added as part of the Appendix

Acquisition and consolidation of hierarchical representations of space

Navigation – the ability to reach targets which are no visible from the current position - depends on the correct recall of the desired target and the environment between one's current position and this target. The content of these representations are subject to influences from different modalities, e.g. vision, and language. A place can be recognized through different cues, e.g. due to a salient object, but also because of the angles of the routes at an intersection, or a name. The location of places as well as the routes connecting them can be integrated and memorized in an allocentric, survey-like representation. Depending on the amount of detail, the granularity level of a representation can be coarser or finer; the different levels are organized hierarchically. Characteristics of a superordinate category, like a region, can affect the perception of its constituting elements, the places; an inheritance of qualities from region to place levels is possible. The formation of superordinate categories depends both on environmental factors as well as individual ones: what is recognized, what is remembered, and which predictions are drawn from this representation? In this dissertation I examine the acquisition of representations of space, in order to identify features that are well suited for being remembered and auxiliary for navigation. I have two research foci: First, I examine the impact of language by using different hierarchically structured naming schemes as place names. Wiener & Mallot (2003) found that characterizing places only with landmarks belonging to different semantic categories influenced route choice as well as the representations of space. I compare these findings to the impact of different naming schemes. I show that there are naming schemes that may influence behavior in a similar way as a landmark does, but that seeing something and reading its name is by far the same thing. The second part focuses on the content of representations established during navigation. With three different navigation experiments, I examine the content of the concepts of space that are acquired during navigation. What is remembered - the location of places, the routes, or the hierarchical structure of the experimental environment? Are there features that are more likely to be consolidated during sleep, e.g., the transfer of concrete knowledge about places and routes into an abstract, survey-like representation? I show that there are improvements in one wayfinding task correlated to sleep. In the other experiments, learning effects were found for both groups. I also address the question of suitable parameters for measuring survey knowledge

Hierarchical inference as a source of human biases

The finding that human decision-making is systematically biased continues to have an immense impact on both research and policymaking. Prevailing views ascribe biases to limited computational resources, which require humans to resort to less costly resource-rational heuristics. Here, we propose that many biases in fact arise due to a computationally costly way of coping with uncertainty—namely, hierarchical inference—which by nature incorporates information that can seem irrelevant. We show how, in uncertain situations, Bayesian inference may avail of the environment’s hierarchical structure to reduce uncertainty at the cost of introducing bias. We illustrate how this account can explain a range of familiar biases, focusing in detail on the halo effect and on the neglect of base rates. In each case, we show how a hierarchical-inference account takes the characterization of a bias beyond phenomenological description by revealing the computations and assumptions it might reflect. Furthermore, we highlight new predictions entailed by our account concerning factors that could mitigate or exacerbate bias, some of which have already garnered empirical support. We conclude that a hierarchical inference account may inform scientists and policy makers with a richer understanding of the adaptive and maladaptive aspects of human decision-making
