PSYCH 1X03 Study Guide - Quiz Guide: Working Memory Training, Fluid And Crystallized Intelligence, Intelligence Quotient
Document Summary
Fluid intelligence reflects how well you handle a new task rather than what facts you have: studies have found that it is heritable; however, intelligence can be honed. Prefrontal cortex executive function; regulates attention, modulates impulses, coordinates information from other brain regions. N-back test participants asked to keep track of something that appeared n positions back in a series. After n-back training : found that those who practiced the task learned to resist the impulse to respond automatically to a stimulus. Scanned the brain while doing the tests: before: greatest activation in parts of the prefrontal and parietal cortex, after: less activation in those regions. Working memory training leads to more efficient brain activation. Parts of the brain that become more efficient through training are better prepared for the task (more blood flow). Problem solving ability is a relative indicator of intelligence. Deductive reasoning ideas/general information specific conclusions. The use of current knowledge to come to a specific conclusion.
