SUMMARY:Thesis defense - Emilien Bonhomme
DESCRIPTION:\n	\n		\n			Videoconference : https://teams.live.com/meet/94221806454556 \nDefense in french \n\nTitre\nIdentification of behavioral and physiological markers capable of predicting the quality of vehicle take-over in level 3 autonomous driving. \n(Identification des marqueurs comportementaux et physiologiques capables de prédire la qualité de la reprise en main du véhicule en conduite autonome de niveau 3) \nAbstract\nThe development of conditionally automated driving systems is expanding quickly. The partial delegation of the driving activity in an autonomous vehicle questions the driver’s ability to takeover the vehicle in a risky situation.\nThe objective of our work is to identify physiological and behavioral markers capable to predict response time (TOT) and the takeover quality. 32 volunteers (43 ± 16 years 16 men) carried out simulated driving where events (object on the road\, bad weather\, absence of road markings) required a takeover. Before each takeover request (TOR)\, drivers performed various non-driving tasks (NDRT) such as listening to the radio\, reading a book\, watching a video…\nElectrocardiographic (ECG)\, electroencephalographic (EEG) and oculomotor (OM) markers were recorded 2 minutes before the takeover and analyzed. These markers\, age\, gender and nature\, duration\, solicitation of the hands and gaze of NDRTs were included in our statistical models (binary logistic regressions\, automatic linear models\, Youden index\, ROC curves).\nTakeovers are qualified in 4 ways. Qualification 1 (Q1) is based on the time to collision (TTC\, time separating the vehicle from the obstacle when the lane change is engaged) and the presence or absence of a collision. Qualification 2 (Q2) uses the previous 2 criteria and the velocity of the steering wheel rotation. Qualification 3 (Q3) includes the first 2 criteria and the verification of the mirrors. And qualification 4 (Q4) by the presence or not of a collision\, and the inappropriate line crossing (ILC).\nOur results show that TOT depends neither on age nor gender of the drivers. The longest TOTs are observed when the NDRT has a strong manual component or requires a strong solicitation of the head position during the takeover. In the case of a takeover with a lane change\, the TOT is the main factor influencing the takeover quality: the longer the TOT\, the poorer the quality of the takeover. The nature and duration of the NDRT do not change the takeover quality. Age has an impact on the takeover quality in Q2 and Q3: older drivers are less successful at takeover than younger ones because they have more unstable lateral control of the vehicule (higher standard deviation of the velocity of steering wheel rotation) and poorer analysis of the scene (lack of mirrors verification). On the other hand\, age does not influence either longitudinal control (TTC) or the presence of collisions. In the case of a takeover without lane change\, the takeover quality (Q4) is mainly determined by age: older subjects perform less well than younger subjects due to poor lateral control. It is above all age that determines the quality of recovery (Q4): elderly subjects (61-75) are less successful than younger subjects because of a worse lateral control.\nNone of our models can predict TOT or Q1 takeover quality. The combination of OM parameters (duration of fixations\, and pupil diameter) and EEG (Frontal Theta) are the markers that allow better predicting of take over quality in Q2. The OM parameters (frequency and duration of fixations\, and distance of saccades) allow the prediction of the quality of recovery in Q3. Associated EEG markers (LFHF ratio\, High Beta band in Cz\, Theta / Beta ratio in frontal) and OM (mean pupil diameter)\, can predict the quality of recovery in Q4.\nOur results will make it possible in the future to improve new models (braking\, steering or steering / braking model) capable of better explaining and / or predicting the behavior of the driver during takeover in level 3 autonomous driving. \n  \nPublications\nY.

SUMMARY:Webinar - Nils Kolling
DESCRIPTION:\n	\n		\n			On Zoom : https://bit.ly/2OJF9nF \n\nTitle: Planning\, motivation and decision making during reward-guided choice and learning \nAbstract\nDeciding between apples and oranges has been an age-old question not just for hungry shoppers but within the field of decision-making research. However\, very rarely have researchers considered the possibility to reject either and move on to the next shelf. I have previously argued that such a sequential decision making framework is not just essential for understanding foraging in animals in the wild\, but also ecological\, real life\, behaviour in humans1\,2. While it is intuitive that real life decision strategies require temporally extended coherent behaviours2 and rely on prospection\, maintained motivation and sequential adaptation\, those cognitive and neural processes remain poorly understand. In the first part of my talk I will present our recent cognitive model for sequential search decisions\, its underlying neural dynamics3. In the second part I will talk about how more complex sequential behaviours could be supported by learning. Specifically\, I will discuss multiple representations of changing reward environments in the anterior cingulate cortex4\,5 and how the changeability of the reward environment can affect how rare reward experiences are processed in orbitofrontal cortex. \nReferences \n\nKolling N\, Akam T.
