An application of the poisson race model to confidence calibration.
In tasks as diverse as stock market predictions and jury deliberations, a person's feelings of confidence in the appropriateness of different choices often impact that person's final choice. The current study examines the mathematical modeling of confidence calibration in a simple dual-choice task. Experiments are motivated by an accumulator model, which proposes that information supporting each alternative accrues on separate counters. The observer responds in favor of whichever alternative's counter first hits a designated threshold. Confidence can then be scaled from the difference between the counters at the time that the observer makes a response. The authors examine the overconfidence result in general and present new findings dealing with the effect of response bias on confidence calibration.next Image 1 of 2

Myanmar State Counsellor Aung San Suu Kyi has arrived in Cambodia on an official visit to strengthen ties between the countries.

The three-day visit starting Monday is the first since Suu Kyi became her country's head of government in 2016. Cambodia's foreign ministry says she will meet with Prime Minister Hun Sen, King Norodom Sihamoni and other Cambodian officials before visiting the famous Angkor Wat archaeological complex.

Suu Kyi arrived from Beijing, where both she and Hun Sen attended a forum about China's multibillion-dollar Belt and Road Initiative. Representatives of 37 countries were at the meeting on the massive infrastructure-building plan.

Myanmar and Cambodia have both grown closer to China in reaction to pressure from Western nations over human rights issues.
