Manipulation of physical models such as tangrams and tiles is a popular approach to teaching early mathematics concepts. This pedagogical approach is extended by new computational media, where mathematical entities such as equations and vectors can be virtually manipulated. The cognitive and neural mechanisms supporting such manipulation-based learning—particularly how actions generate new internal structures that support problem-solving—are not understood. We develop a model of the way manipulations generate internal traces embedding actions, and how these action-traces recombine during problem-solving. This model (...) is based on a study of two groups of sixth-grade students solving area problems. Before problem-solving, one group manipulated a tangram, the other group answered a descriptive test. Eye-movement trajectories during problem-solving were different between the groups. A second study showed that this difference required the tangram's geometrical structure, just manipulation was not enough. We propose a theoretical model accounting for these results, and discuss its implications. (shrink)

People implicitly associate the “past” and “future” with “front” and “back” in their minds according to their cultural attitudes toward time. As the temporal focus hypothesis proposes, future-oriented people tend to think about time according to the future-in-front mapping, whereas past-oriented people tend to think about time according to the past-in-front mapping. Whereas previous studies have demonstrated that culture exerts an important influence on people's implicit spatializations of time, we focus specifically on religion, a prominent layer of culture, as potential (...) additional influence on space-time mappings. In Experiment 1 and 2, we observed a difference between the two religious groups, with Buddhists being more past-focused and more frequently conceptualizing the past as ahead of them and the future as behind them, and Taoists more future-focused and exhibiting the opposite space-time mapping. In Experiment 3, we administered a religion prime, in which Buddhists were randomly assigned to visualize the picture of the Buddhas of the Past or the Future. Results showed that the pictorial icon of Dipamkara increased participants' tendency to conceptualize the past as in front of them. In contrast, the pictorial icon of Maitreya caused a dramatic increase in the rate of future-in-front responses. In Experiment 4, the causal effect of religion on implicit space-time mappings was replicated in atheists. Taken together, these findings provide converging evidence for the hypothesized causal role of religion for temporal focus in determining space-time mappings. (shrink)

People can represent temporal stimuli (e.g., pictures depicting past and future events) as spatially connoted dimensions arranged along the three main axes (horizontal, sagittal, and vertical). For example, past and future events are generally represented, from the perspective of the individuals, as being placed behind and in front of them, respectively. Here, we report that such a 3D representation can also emerge for facial stimuli of different ages. In three experiments, participants classified a central target face, representing an individual at (...) different age stages, as younger or older than the reference face of 40 years. Manual responses were provided with two keys placed along the horizontal axis (Experiment 1), the sagittal axis (Experiment 2), and the vertical axis (Experiment 3). The results indicated that the younger faces were represented on the left/back/top side of the space, whereas the older faces were represented on the right/forward/bottom side of the space. Furthermore, in all experiments, the latencies decreased with the absolute difference between the age of the target face and that of the reference face (i.e., a distance effect). Overall, this work suggests that the spatial representation of time includes social features of the human face. (shrink)

concepts cannot be directly perceived through senses. How do people represent abstract concepts in their minds? According to the Conceptual Metaphor Theory, people tend to rely on concrete experiences to understand abstract concepts. For instance, cognitive science has shown that time is a metaphorically constituted conception, understood relative to concepts like space. Across many languages, the “past” is associated with the “back” and the “future” is associated with the “front”. However, space-time mappings in people’s spoken metaphors are not always consistent (...) with the implicit mental metaphors they are using to conceptualize time in their minds, suggesting a dissociation between temporal language and temporal thought. Beyond the influences of language, the Temporal Focus Hypothesis proposes that people’s spatial conceptions of time are shaped by their attentional focus on temporal events. In general, people conceptualize the past as being in front to the extent that their culture is past-oriented, and the future as being in front to the extent that their culture is future-oriented. Recent lines of research have provided preliminary evidence that people’s implicit space-time mappings are malleable and likely result from multiple factors related to temporal focus, ranging from those relating to contextual features, such as cultural attitudes toward time, to those more tightly tied to the individual, such as age-related differences. By building upon and extending these findings, the overall aim of this thesis is to ascertain the generalizability of the Temporal Focus Hypothesis and further investigate the range of factors that may influence people’s spatializations of time, focusing specifically on previously unexplored within-cultural differences, political ideology, religion, real life experiences, pregnancy, temporal landmarks, circadian rhythms and chronotype, and personality. Together, these studies demonstrate that people’s implicit space-time mappings may vary according to their temporal focus, which can be explained by the Temporal Focus Hypothesis. The findings of these studies also shed new light on the Temporal Focus Hypothesis by extending the range of factors that may influence people’s conceptions of time, and reveal the malleability and flexibility of time representations.
