Two experiments investigated the role of spatial abilities on uninhabited ground vehicle (UGV) performance under two different viewing conditions: direct line of sight and teleoperation. The ability to operate a mobile robot was indexed by task completion time and total number of course collisions. Results showed that participants with higher spatial abilities exhibited superior performance in both direct line of sight and teleoperation. Performance under direct line of sight was correlated with both spatial relations and spatial visualization, whereas performance during teleoperation was only correlated with spatial relations ability. Understanding the roles of spatial abilities under different viewing conditions will aid in the advancement of selection criteria and training paradigms for robot operators.

<p><strong>Abstract.</strong> Spatial thinking, comprised of concepts, representations and spatial abilities, is a cognitive activity developed in everyday living, and can be systematized through different school disciplines, mainly Geography. The comprehension of this concept and the investigation of how it can be developed and systematized in schools are critical points, involving different languages that represent the space. Our main objective is to propose theoretical and methodological references for the spatial knowledge of children aged between 4 and 6 years old. The research is based on the following question: Which spatial abilities and concepts can be addressed in activities aimed at developing spatial thinking in children aged 4 to 6 years old? To answer this question and achieve the main objective, the specific objectives were: a) to investigate and analyze the pertinence, possibilities and approaches regarding the spatial notions in children’s education; b) develop teaching situations based on guiding theories about spatial thinking, children’s drawing and the concept construction under a historical and cultural perspective; c) understand the patterns in children’s graphic representations; and d) analyze the children’s dialogues. The analysis of the research data allowed us to conclude that drawing is part of the cartographic initiation, and words are fundamental elements that concretize the way of thinking, in this case, spatial thinking ability. In this research, we reaffirm the direct relationship between Geography and the development of spatial thinking, considering the very nature of this Science, and Cartography as the language used to materialize this way of thinking.</p>

Variance in spatial abilities are thought to be determined by in utero levels of testosterone and oestrogen, measurable in adults by the length ratio of the 2nd and 4th digit (2D:4D). We confirmed the relationship between 2D:4D and spatial performance using rats in two different tasks (paired-associate task and watermaze) and replicated this in humans. We further clarified anatomical and functional brain correlates of the association between 2D:4D and spatial performance in humans.

Objectives: The aim of this study was to examine the relationship between the spatial abilities of medical school students and their learning in anatomy. Methods: The spatial abilities of the 120 students (74 females, 46 males) were examined using Mental Rotation Test (MRT). The relationship between the mental rotation scores and the mean scores of their practical and theoretical anatomy examinations was determined in terms of gender. Results: The study revealed that mental rotation skills of female participants were lower than males; however, there was no significant difference in their exam (theoretical and practical anatomy examinations) scores in terms of gender. The spatial ability of the students had a low level significant effect on their anatomy scores, regarding practical applications. Conclusion: The results of the study revealed a significant relationship between students’ spatial ability and their success in practical anatomy examinations. This suggests that improving spatial ability skills may have a significant contribution to practical anatomy learning and may be considered as a part of anatomy education.

AbstractWe present the first sample of diffuse interstellar bands (DIBs) in the nearby galaxy M33. Studying DIBs in other galaxies allows the behaviour of the carriers to be examined under interstellar conditions which can be quite different from those of the Milky Way, and to determine which DIB properties can be used as reliable probes of extragalactic interstellar media. Multi-object spectroscopy of 43 stars in M33 has been performed using Keck/DEIMOS. The stellar spectral types were determined and combined with literature photometry to determine the M33 reddenings E(B-V)M33. Equivalent widths or upper limits have been measured for the λ5780 DIB towards each star. DIBs were detected towards 20 stars, demonstrating that their carriers are abundant in M33. The relationship with reddening is found to be at the upper end of the range observed in the Milky Way. The line of sight towards one star has an unusually strong ratio of DIB equivalent width to E(B-V)M33, and a total of seven DIBs were detected towards this star.
