Psychologists device free test for measuring intelligence

A team of psychologists at UC Riverside and UC Irvine has now developed a highly comparable free test that takes roughly 10 সম্পূর্ণ করতে মিনিট. Called the University of California Matrix Reasoning Task, or UCMRT, the user-friendly test measures abstract problem-solving ability and works on tablets and other mobile devices.

গবেষকরা রিপোর্ট in the journal Behavior Research Methods that UCMRT, which they tested on 713 undergraduate students at UC Riverside and UC Irvine, is a reliable and valid measure of nonverbal problem solving that predicts academic proficiency and measures “তরল —intelligence that is not dependent on pre-existing knowledge and is linked to reasoning and problem solving. Like APM, the test differentiates among people at the high end of intellectual ability. Compared to APM, the UCMRT offers three alternate versions, allowing the test to be used three times by the same user.

Performance on UCMRT correlated with a math test, college GPA, as well as college admissions test scores,” said Anja Pahor, a postdoctoral researcher who designed UCMRT’s problems and works at both UC campuses. “Perhaps the greatest advantage of UCMRT is its short administration time. আরও, it is self-administrable, allowing for remote testing. Log files instantly provide the number of problems solved correctly, incorrectly, or skipped, which is easily understandable for researchers, clinicians, and users. Unlike standard paper and pencil tests, UCMRT provides insight into problem-solving patterns and reaction times.

Along with many psychologists using Raven’s APM, Pahor and her co-authors—UCR’s Aaron R. Seitz and Trevor Stavropoulos; and UCI’s Susanne M. Jaeggi—realized that APM is not well suited for their studies given its cost, the time it takes to complete the test, and a lack of alternative, cross-validated forms in which participants are confronted with novel questions each time they take the test. তাই, the psychologists opted to create their own version of the test.

UCMRT predicts better than Raven’s APM,” said Seitz, a professor of psychology, director of the Brain Game Center at UCR, and Pahor’s mentor. “Intelligence tests are big-money operations. Companies that create the tests often levy a hefty charge for their use, an impediment to doing research. Our test, available for free, levels the playing field for a vast number of researchers interested in using it. We are already working to make UCMRT better than it already is. Technology has changed over the decades that APM has been around, and people’s expectations have changed accordingly. It’s important to have tests that reflect these changes and respond in a timely manner to them.

Pahor said UCMRT has only 23 problems for users to solve (APM, in contrast, আছে 36), yet delivers measurements that are as good as those from APM.

Researchers interested in using the test may contact Pahor at anjap@ucr.edu. They would be asked to download an app either in Google Play or iTunes and can start administering it immediately. Data from the tests are stored on the device itself and on a secure server.

Jaeggi, who also mentors Pahor and is an associate professor in the School of Education at UCI where she leads the Working Memory and Plasticity Laboratory, adds, “The way we set up and designed UCMRT allows the inclusion of variants that can be used for populations across the lifespan from young children to older adults. The problems we designed are visually appealing, making it easy to motivate participants to complete the task. উপরন্তু, there are minimal verbal instructions and participants can figure out what to do by completing the practice problems.

Although UCMRT instructions are currently in English, the test can be easily localized to include relevant translations, Seitz said.

We are motivated by helping the scientific community and want to create versions of UCMRT for different age groups and abilities,” সে যুক্ত করেছিল. “This test could help with early intervention programs. We are already working on a project with California State University at San Bernardino to move forward with that.

UCMRT is largely based on matrix problems generated by Sandia National Laboratories. Most of the ‘s matrices are inspired by those produced by the lab. Stavropoulos at the UCR Brain Game Center programmed UCMRT’s problems.
