A psychometric analysis of chess expertise

Area of Science:

• Cognitive Psychology
• Psychometrics
• Chess Expertise Research

Background:

• Assessing chess expertise requires reliable and valid measurement tools.
• Existing methods may not fully capture the multifaceted nature of chess proficiency.

Purpose of the Study:

• To introduce and validate the Amsterdam Chess Test (ACT), a novel instrument for measuring chess playing proficiency.
• To examine the relationship between chess expertise, knowledge, motivation, and memory.

Main Methods:

• The Amsterdam Chess Test (ACT) comprises five tasks: choose-a-move, motivation questionnaire, predict-a-move, verbal knowledge questionnaire, and recall.
• Test validity was established against the Elo chess rating system.
• Response latencies were incorporated into test scores.

Main Results:

• The ACT demonstrated high reliability and predictive validity in a sample of active chess players.
• Hypotheses regarding chess expertise, knowledge, motivation, and memory were tested.
• Including response latencies improved criterion validity, especially for simpler items.

Conclusions:

• The Amsterdam Chess Test (ACT) is a reliable and valid measure of chess expertise.
• The findings contribute to understanding the cognitive and motivational factors underlying chess skill.
• Response latencies offer valuable additional information for assessing chess proficiency.
