Negative numbers are central in math. However, they are abstract, hard to learn, and manipulated slower than positive numbers regardless of math ability. It suggests that confidence, namely the post-decision estimate of being correct, should be lower …
Exposure to violence has lasting effects on economic behavior years after it has ended. Previous literature has proved that there is an increase in altruism, impatience, and risk-seeking. However, it is unknown if regular citizens, not directly …
Fractions are crucial, from math and science education to daily activities, but they are hard. A puzzling aspect of fractions is that people over-rely on the numerator when comparing a pair of fractions. Previous work has considered this numerator …
Humans have great difficulty comparing quotients including fractions, proportions, and probabilities and often erroneously isolate the whole numbers of the numerators and denominators to compare them. Some have argued that the whole number bias is a …
A dominant mechanism in the Judgment and Decision Making literature states that information is accumulated about each choice option until a decision threshold is met. Only after that threshold does a subject start to execute a motor response to …
Gaze, pointing, and reaching movements are thought to provide a window to internal cognitive states. In the case of numerical cognition, it has been found that the left-right deviation of a reaching movement is modulated by the relative magnitude of …
Intertemporal decisions usually involve numbers: subjects decide between rewards, with different delays and probabilities. This paper is a brief overview of findings in the area of number cognition, followed by some theoretical applications of these …
In this work we asked if risk attitudes influence the way agents learn in a probabilistic environment. For that purpose, 31 male students played a version of a well-known game called the multi-armed bandit (with four levers/buttons). We found that …
Neuroeconomics gives a material foundation to economics. The basic framework of this paper is one that takes into account cognitive psychology, economics, biology and neuroscience in general. Specifically, it is a review of findings which aim to make …
