Knowledge of Fractions and Long Division Predicts Long-Term Math Success
From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy. Yet, over the past 30 years, mathematics achievement of U.S. high school students has remained stagnant — and significantly behind many other countries, including China, Japan, Finland, the Netherlands and Canada. A research team led by Carnegie Mellon University’s Robert Siegler has identified a major source of the gap — U. S. students’ inadequate knowledge of fractions and division. Although fractions and division are taught in elementary school, even many college students have poor knowledge of them.

New Research From Current Directions in Psychological Science
Yuko Munakata, Hannah R. Snyder, and Christopher H. Chatham When children are young, they can get stuck in routine ways of thinking and behaving. As children grow, they develop the ability to break out of routines and think more flexibly. In this article, the authors discuss how the development of abstract goal representations supports three key transitions that lead to more flexible behavior. They conclude by discussing the current and future direction of this research. The Brain's Learning and Control Architecture Jason M.

Expectations influences outcomes
United Press International: Suggestion -- a rabbit's foot or a lucky coin -- can influence how people perform on learning and memory tasks, New Zealand and U.S researchers said. Maryanne Garry and Robert Michael of Victoria University of Wellington, New Zealand, and Irving Kirsch of Harvard Medical School in Boston said the powerful and persuasive effect that suggestion has relies on a person's "response expectancies," or the ways in which people anticipate responses in various situations. These expectations set people up for automatic responses that actively influence how people get to the outcome expected, the researchers said.

Why Smart People Are Stupid
The New Yorker: Here’s a simple arithmetic question: A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost? The vast majority of people respond quickly and confidently, insisting the ball costs ten cents. This answer is both obvious and wrong. (The correct answer is five cents for the ball and a dollar and five cents for the bat.) For more than five decades, Daniel Kahneman, a Nobel Laureate and professor of psychology at Princeton, has been asking questions like this and analyzing our answers. His disarmingly simple experiments have profoundly changed the way we think about thinking.

Diamond Jubilee: Why The ‘Right Kind Of Patriotism’ Benefits Health
Huffington Post: Ignore those twinges of cynicism and embrace your inner patriot this weekend, as studies regularly show that nationalism makes people happy. However, how happy you feel also depends on what you’re taking pride in, noted researchers earlier this year. In a report for Psychological Science, Matthew Wright, a political scientist at American University, and Tim Reeskens, a sociologist from Catholic University in Belgium found that more national pride correlated with greater personal wellbeing. But they also noticed that those individuals who connected nationalism with respect for a country’s institutions and values, rather than race or religion, were the most content.
