The study investigates two different ways of guiding the addressee of an explanation - an explainee, through action demonstration: contrastive and non-contrastive. Their effect was tested on attention to specific action elements (goal) as well as on event memory. In an eye-tracking experiment, participants were shown different motion videos that were either contrastive or non-contrastive with respect to the segments of movement presentation. Given that everyday action demonstration is often multimodal, the stimuli were created with re- spect to their visual and verbal presentation. For visual presentation, a video combined two movements in a contrastive (e.g., Up-motion following a Down-motion) or non-contrastive way (e.g., two Up-motions following each other). For verbal presentation, each video was combined with a sequence of instruction descriptions in the form of negative (i.e., contrastive) or assertive (i.e., non-contrastive) guidance. It was found that a) attention to the event goal increased for this condition in the later time window, and b) participants’ recall of the event was facilitated when a visually contrastive motion was combined with a verbal contrast.

Here we theoretically demonstrate the realization of EPs in a system\nwith significant nonlinearity, a non-equilibrium exciton-polariton condensate.\nWith the possibility to control loss and gain and nonlinearity by optical\nmeans, this system allows for a comprehensive analysis of the interplay of\nnonlinearities (Kerr-type and saturable gain) and non-Hermiticity. Not only do\nwe find that EPs can be intentionally shifted in parameter space by the\nsaturable gain, we also observe intriguing rotations and intersections of\nRiemann surfaces, and find nonlinearity-enhanced sensing capabilities. Our\nresults are quite general in nature and illustrate the potential of tailoring\nspectral topology and related phenomena in non-Hermitian systems by\nnonlinearity.","lang":"eng"}],"status":"public","type":"preprint","publication":"arXiv:2305.04855","title":"Tweaking Spectral Topology and Exceptional Points by Nonlinearity in\n Non-Hermitian Polariton Systems","date_updated":"2023-09-29T11:28:01Z","author":[{"last_name":"Wingenbach","full_name":"Wingenbach, Jan","first_name":"Jan"},{"first_name":"Stefan","full_name":"Schumacher, Stefan","last_name":"Schumacher"},{"full_name":"Ma, Xuekai","last_name":"Ma","first_name":"Xuekai"}],"date_created":"2023-09-29T09:18:52Z","year":"2023","citation":{"apa":"Wingenbach, J., Schumacher, S., & Ma, X.
