LIRa Session: Katrin Schulz

26 Feb '19

Dear all, The next LIRa session will take place on Thursday, February 28th. Please, find the details below: Speaker: Katrin Schulz Date and Time: Thursday, February 28th 2019, 16:30-18:00 Venue: ILLC Seminar Room F1.15, Science Park 107. Title: Conditionals, Causality and Conditional Probability. Abstract. The appropriateness, or acceptability, of a conditional does not just \'go with\' the corresponding conditional probability. A condition of dependence is required as well (cf. Douven, 2008, 2016; Skovgaard-Olsen et al., 2016). In this talk a particular notion of dependence is proposed. It is shown that under both a forward causal and a backward evidential (or diagnostic) reading of the conditional, this appropriateness condition reduces to conditional probability under some natural circumstances. Because this is in particular the case for the so-called diagnostic reading of the conditional, this analysis might help to explain some of Douven and Verbrugge\'s (2010) empirical observations. (Joint work with Robert van Rooij) Hope to see you there! The LIRa team

LIRa Session: Leendert van Maanen

Dear all, Tomorrow we will have our next LIRa session. Please, find the details below: Speaker: Leendert van Maanen (Department of Psychological Methods, UvA) Date and Time: Thursday, February 21st 2019, 16:30-18:00 Venue: ILLC Seminar Room F1.15, Science Park 107. Title: Evidence accumulation modeling to understand simple and complex behavior. Abstract. In this talk, I will highlight the use of accumulator models to study simple and more complex cognitive processing. The central idea of an accumulator model is that in order to perform an action – either to execute observable behavior or in order to trigger another internal cognitive process – cognitive agents need to accumulate evidence over time in support of that action. Formalisms of this idea have been used to understand how experimental manipulations influence both response times and type of choices. After an introduction of the canonical accumulator model, I will discuss recent work that suggests a close relationship between people’s sense of time and evidence accumulation processes in simple choice behavior. I will end by discussing two potential directions that can be taken to apply evidence accumulation to more complex cognitive processes such as reasoning. The first direction involves the idea that certain complex cognitive processes can also be understood as evidence accumulation. The second direction involves EEG to identify critical cognitive processing stages in more complex tasks. Hope to see you there! The LIRa team

LIRa Session: Aidan Lyon

Dear all, Tomorrow we will have our next LIRa session. Please, find the details below: Speaker: Aidan Lyon (ILLC) Date and Time: Thursday, February 14th 2019, 16:30-18:00 Venue: ILLC Seminar Room F1.15, Science Park 107. Title: Psychedelic Experience and the Mathematics of Hallucination. Abstract. In this talk, I will present three kinds of mathematical model of psychedelic hallucinations: (i) those based on Turing bifurcation patterns, (ii) Bayesian / predictive coding models, and (iii) models based on convolutional neural networks. I will discuss the relationships between the three kinds of model and propose an account of psychedelic hallucination that unifies the models. I will also discuss the philosophical implications of this unified account. Hope to see you there! The LIRa team
