A Computational Model of Children's Learning and Use of Probabilities Across Different Ages

no code implementations6 May 2023 Zilong Wang, Thomas R. Shultz, Ardvan S. Nobandegani

Recent empirical work has shown that human children are adept at learning and reasoning with probabilities.

A Neural Model of Number Comparison with Surprisingly Robust Generalization

no code implementations13 Oct 2022 Thomas R. Shultz, Ardavan S. Nobandegani, Zilong Wang

We propose a relatively simple computational neural-network model of number comparison.

Cognitive Models as Simulators: The Case of Moral Decision-Making

no code implementations8 Oct 2022 Ardavan S. Nobandegani, Thomas R. Shultz, Irina Rish

In this work, we substantiate the idea of $\textit{cognitive models as simulators}$, which is to have AI systems interact with, and collect feedback from, cognitive models instead of humans, thereby making their training process both less costly and faster.

Decision Making Fairness +1

Bringing Order to the Cognitive Fallacy Zoo

no code implementations15 Oct 2018 Ardavan S. Nobandegani, William Campoli, Thomas R. Shultz

In the eyes of a rationalist like Descartes or Spinoza, human reasoning is flawless, marching toward uncovering ultimate truth.

Over-representation of Extreme Events in Decision-Making: A Rational Metacognitive Account

no code implementations30 Jan 2018 Ardavan S. Nobandegani, Kevin da Silva Castanheira, A. Ross Otto, Thomas R. Shultz

The Availability bias, manifested in the over-representation of extreme eventualities in decision-making, is a well-known cognitive bias, and is generally taken as evidence of human irrationality.

Coupled feedback loops maintain synaptic long-term potentiation: A computational model of PKMzeta synthesis and AMPA receptor trafficking

1 code implementation2 Dec 2017 Peter Helfer, Thomas R. Shultz

In long-term potentiation (LTP), one of the most studied types of neural plasticity, synaptic strength is persistently increased in response to stimulation.

Converting Cascade-Correlation Neural Nets into Probabilistic Generative Models

no code implementations18 Jan 2017 Ardavan Salehi Nobandegani, Thomas R. Shultz

Humans are not only adept in recognizing what class an input instance belongs to (i. e., classification task), but perhaps more remarkably, they can imagine (i. e., generate) plausible instances of a desired class with ease, when prompted.

Neural Implementation of Probabilistic Models of Cognition

no code implementations13 Jan 2015 Milad Kharratzadeh, Thomas R. Shultz

Bayesian models of cognition hypothesize that human brains make sense of data by representing probability distributions and applying Bayes' rule to find the best explanation for available data.

Managing Uncertainty in Rule Based Cognitive Models

no code implementations27 Mar 2013 Thomas R. Shultz

An experiment replicated and extended recent findings on psychologically realistic ways of modeling propagation of uncertainty in rule based reasoning.
