SUMMARY:Martin Rolfs (Science of Intelligence)\, "Looking for Action in Perception"
DESCRIPTION:Abstract\nActions affect perception directly and in multiple ways\, exerting their influence (1) by modifying parts of the external world\, (2) through internal processes accompanying movement preparation\, and (3) through the sensory consequences of moving the sensory surface itself (i.e.\, in vision\, the retina). To understand these influences\, psychology and neuroscience have long recognized the necessity to study perception in active observers. Despite this recognition\, the consequences of moving the sensory surface itself (point 3 above) have been considered a nuisance\, to the extent that perceptual processing — across sensory modalities — needs to be attenuated or suppressed during movement execution. I will discuss recent evidence that studying the immediate sensory consequences as a functional element of perceptual processes is a fruitful approach that may lead to a different understanding of the mechanisms underlying perception. The goal is to develop a set of hallmarks of active perceptual systems\, which may represent different degrees to which actions are ingrained into the perceptual processing architecture. I will propose a recipe for testing this proposal in active observers suggesting\, perhaps counterintuitively\, that a deeper understanding of perception requires shifting the focus of perceptual research to motor control and action kinematics. PS: Most of these ideas will be half-baked at the time of presentation. \nThe Zoom Link will be sent the day before the lecture. (Contact communication@scioi.de for specific questions)

SUMMARY:Marc Toussaint (Science of Intelligence)\, "Do We Need Reasoning?"
DESCRIPTION:Reasoning (or planning\, rational decision making) seems a core aspect of intelligence — but what exactly does that mean? If we observe clever behavior in an animal\, can we claim it is based on reasoning? And doesn’t the success of deep RL show us that we (as engineers) do not need reasoning? I’ll discuss reasoning as a means to represent behavior and what the point of that might be. \nThe Zoom Link will be sent the day before the lecture.

SUMMARY:Antje Nuthmann (University of Kiel)\, “Real-World Scene Perception and Search From Foveal to Peripheral Vision”
DESCRIPTION:It is a commonly held assumption that the fovea is where the interesting action occurs. To scrutinize this assumption\, we conducted a series of experiments that addressed the following question: How important are the different regions of the visual field for gaze guidance in everyday visual-cognitive tasks? Following on from classic findings for sentence reading\, I will present key results from various experiments in which observers had to search for a target within static or dynamic images of real-world scenes. Each scene image contained exactly one target\, which was either contextually relevant (e.g.\, “Look for the apple”) or not (e.g.\, “Look for the ‘T’”). Gaze-contingent scotomas were used to selectively deny information processing in the fovea\, parafovea\, or periphery. Overall\, the results suggest that foveal vision is less important and peripheral vision is more important for scene perception and search than previously thought. The importance of foveal vision was found to depend on the specific requirements of the task. Finally\, when observers searched for a static target in dynamic scenes\, only their very first saccade was guided by task-irrelevant motion in extrafoveal and peripheral vision.\n\n(Photo © Jürgen Haacks\, Uni Kiel)\nThe Zoom Link will be sent the day before the lecture.
