Dear all, We would like to invite you to the first event of the ELTE Cognitive Seminar series of the Spring semester. We are delighted to announce that our first guest will be Hanna Marno, who is going to present her talk originally planned for the previous Fall semester. *ELTE Cognitive Seminar Invitation* *Time and date: *14:00 (CET), Tuesday, 08. 02. 2022. *Speaker:* Hanna Marno (Central European University, Eötvös Loránd University) *Title:* Learning from action observation: the importance of communication over efficiency Abstract*:* Ostensive cues, such as eye-contact or calling the other’s name are typically used to inform the addressee about our communicative intention. Furthermore, they can elicit an expectation of relevance about the communicated information, both in the case of adults and infants. During observational learning, would this expectation of relevance induce a bias to preferentially learn the communicated action demonstration, even at the expense of its observed efficiency? In my talk, I will present a series of studies testing whether toddlers and young children learn from their own observation of efficiency, assessed by statistical information on reliability of interventions, or from communicatively presented demonstrations, when these two potential types of evidence are contrasted with each other. The findings demonstrate that communicative sanctioning of reliability may override statistical evidence for young learners. Furthermore, our recent evidence with great apes also suggests that ostensive demonstration can elicit an expectation of relevance, potentially leading to a preference to learn from communication, as human children do. *Zoom link:* https://ppk-elte-hu.zoom.us/j/97351319559?pwd=TUNxUGJqekxtckhzMlRLR1I2NWhPd… <https://www.google.com/url?q=https://ppk-elte-hu.zoom.us/j/97351319559?pwd%3DTUNxUGJqekxtckhzMlRLR1I2NWhPdz09&sa=D&source=calendar&usd=2&usg=AOvVaw2eZxWxHG1z-AyyF3mNJXnm> *Meeting ID: *973 5131 9559 *Passcode: *474474 The next event of the ELTE Cognitive Seminar will be a talk by* Gergő Orbán* on *22nd February, at 14:00. *We are looking forward to many of you joining!
