To promote the development of young children's probabilistic intuitions through experience, we focus on the dual nature of probability related to both belief (subjective notion) and frequency (objective notion). This paper reports on the responses of 7-8-year-olds on two tasks used to bridge subjective and objective notions of probability. We explore how these two conceptions interact in children's estimations of the likelihood of outcomes from chance events as new information is obtained from data collected through physical experiments and computer simulations. Our findings suggest that even though children have not yet reached the desired level of quantitative reasoning, several used the data in a reasonable way to update their subjective probabilities based on their personal beliefs. These findings highlight the nascent potential of children to reason about probability when presented with a sequence of activities. These activities are used to support them to state their subjective probability estimations, using a contextually rich continuum, while at the same time recalibrate their estimations to more accurately reflect the theoretical probability.

A new outlier detection method based on convex optimization: application to diagnosis of Parkinson's disease TAYLAN, PAKİZE; Yerlikaya-Ozkurt, Fatma; Bilgic Ucak, Burcu; Weber, Gerhard Wilhelm (Informa UK Limited, 2020-12-01) Neuroscience is a combination of different scientific disciplines which investigate the nervous system for understanding of the biological basis. Recently, applications to the diagnosis of neurodegenerative diseases like Parkinson's disease have become very promising by considering different statistical regression models. However, well-known statistical regression models may give misleading results for the diagnosis of the neurodegenerative diseases when experimental data contain outlier observations that l...
THE ART OF MEMORY IN A PLURALISTIC UNIVERSE: WILLIAM JAMES'S "REPUBLICAN BANQUET" Çırakman, Elif (2007-06-22) The aim of this paper is to conduct an inquiry that would illuminate how a phenomenological account of memory may govern some basic issues of our lives: the meaning of our collectivity and spirituality, the cultural embodiment of our experiences and memories, and their collective status, the question of intimacy and unity in the universe of our experiences. I shall consider this account of memory by focusing on William James's radically empiricist, pluralist, and pragmatic philosophy. In reading James, my a...
A Bayesian inspired approach to reasoning about uncertainty: 'How confident are you?' Kazak, Sibel (2015-01-01) This paper focuses on a task design that is aimed at eliciting young students' reasoning about uncertainty as it relates to their personal degree of confidence through a Bayesian inspired informal inferential reasoning about chance games. This Bayesian inspired approach is described and discussed based on preliminary analyses of data from a teaching experiment in a designed-based research study. With this approach, beginning by a hypothesis (or prediction) about the fairness of a game and revising it based ...
The Impact of modality and feedback on reasoning about base rate neglect problems in behavioral and eye tracking studies: a cognitive science perspective Verim, Burcu; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2014) The base rate fallacy is a type of reasoning error which is rooted in judgements of humans about the likelihood of some state or some event on prior beliefs and intuitions about the representativeness of the problem while neglecting base rate probabilities of this state or event. So far, base rate neglect problems have been presented in the verbal modality, in the form of story scripts. The purpose of this study is to investigate to what extent the different modalities (verbal vs. graphical) have an effect ...
The Understanding of nomativity and free will in games: a developmental study on 2- and 3- year old Turkish children Tunçgenç, Bahar; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2012) This study investigated the understanding of normativity and free will from a developmental perspective. Being a new field of investigation, there is not much research conducted which points to different aspects of normativity. Current study, therefore, aimed to assess Turkish children’s normative development on a sample of 2 and 3 years old in the context of games. It was expected, first, that children would show more protest when there is a norm violation. Moreover, older children would show more normativ...
