Experimental Environment

We report a series of event-related potential experiments designed to dissociate the functionally distinct processes involved in the comprehension of highly restricted lexical-semantic relations (antonyms). We sought to differentiate between influences of semantic relatedness (which are independent of the experimental setting) and processes related to predictability (which differ as a function of the experimental environment). To this end, we conducted three ERP studies contrasting the processing of antonym relations (black-white) with that of related (black-yellow) and unrelated (black-nice) word pairs. Whereas the lexical-semantic manipulation was kept constant across experiments, the experimental environment and the task demands varied: Experiment 1 presented the word pairs in a sentence context of the form The opposite of X is Y and used a sensicality judgment. Experiment 2 used a word pair presentation mode and a lexical decision task. Experiment 3 also examined word pairs, but with an antonymy judgment task. All three experiments revealed a graded N400 response (unrelated > related > antonyms), thus supporting the assumption that semantic associations are processed automatically. In addition, the experiments revealed that, in highly constrained task environments, the N400 gradation occurs simultaneously with a P300 effect for the antonym condition, thus leading to the superficial impression of an extremely “reduced” N400 for antonym pairs. Comparisons across experiments and participant groups revealed that the P300 effect is not only a function of stimulus constraints (i.e., sentence context) and experimental task, but that it is also crucially influenced by individual processing strategies used to achieve successful task performance.

Car Following Model

Abstract Based on reinforcement learning technology, this paper establishes a new driverless car following model. DQN algorithm and traffic simulator are mainly used to train the agent, and the following model is finally obtained. Under the precise and controllable experimental environment, the preset optimization targets can achieve the expected assumption and complete the following behavior. This study will contribute to the development of unmanned vehicles in the future.

- A study has been carried out in order to evaluate the possibility of overcoming children aversion to aerosol therapy as well as facilitating their parents' task. Starting point of this study was the investigation, which was performed through focus groups, clinical interviews and a playful approach, on how children and parents perceive the aerosol therapy. After having identified critical issues and spontaneous proposals to ameliorate aerosol administration, the Authors evaluated the results obtained by the association of the traditional aerosol therapy with a device equipped with educational games. An experimental environment was set up in a school together with a procedure aiming at evaluating the children behavior towards aerosol therapy administered with and without the device equipped with educational games. The results of this monocentric, randomized, cross-over study demonstrated a statistically significant increase of the compliance index when aerosol therapy was administered with the device equipped with educational games, increasing interest, satisfaction and pleasure during the aerosol administration, which was accepted for a longer time.
