Sentence Comprehension: Effectors and Goals, Self and Others. An Overview of Experiments and Implications for Robotics

According to theories referring to embodied and grounded cognition (Barsalou, 2008), language comprehension encompasses an embodied simulation of actions. The neural underpinnings of this simulation could be found in wide neural circuits that involve canonical and mirror neurons (Rizzolatti et al., 1996). In keeping with this view, we review behavioral and kinematic studies conducted in our lab which help characterize the relationship existing between language and the motor system. Overall, our results reveal that the simulation evoked during sentence comprehension is fine-grained, primarily in its sensitivity to the different effectors we employ to perform actions. In addition, they suggest that linguistic comprehension also relies on the representation of actions in terms of goals and of the chains of motor acts necessary to accomplish them. Finally, they indicate that these goals are modulated by both the object features the sentence refers to as well as by social aspects such as the characteristics of the agents implied by sentences. We will discuss the implications of these studies for embodied robotics

Evidence of a Weakly Absorbing Intermediate Mode of Aerosols in AERONET Data from Saharan and Sahelian Sites

Accurate retrievals of aerosol size distribution are necessary to estimate aerosols' impact on climate and human health. The inversions of the Aerosol Robotic Network (AERONET) usually retrieve bimodal distributions. However, when the inversion is applied to Saharan and Sahelian dust, an additional mode of intermediate size between the coarse and fine modes is sometimes seen. This mode explains peculiarities in the behavior of the Angstrom exponent, along with the fine mode fraction retrieved using the spectral deconvolution algorithm, observed in a March 2006 dust storm. For this study, 15 AERONET sites in northern Africa and on the Atlantic are examined to determine the frequency and properties of the intermediate mode. The mode is observed most frequently at Ilorin in Nigeria. It is also observed at Capo Verde and multiple sites located within the Sahel but much less frequently at sites in the northern Sahara and the Canary Islands. The presence of the intermediate mode coincides with increases in Angstrom exponent, fine mode fraction, single-scattering albedo, and to a lesser extent percent sphericity. The Angstrom exponent decreases with increasing optical depth at most sites when the intermediate mode is present, but the fine mode fraction does not. Single-scattering albedo does not steadily decrease with fine mode fraction when the intermediate mode is present, as it does in typical mixtures of dust and biomass-burning aerosols. Continued investigation is needed to further define the intermediate mode's properties, determine why it differs from most Saharan dust, and identify its climate and health effects
