  • While buy cheap wow gold new methods to purportedly sharpen our mental abilities are found in brain training games, apps and websites, a central question is "do they work?"

    New research suggests that brain training programs might strengthen your ability to hold information in mind, but they won bring any benefits to the kind of intelligence that helps you reason and solve problems.

    The findings are published in Psychological Science.

    claims are particularly attractive to parents of children who are struggling in school. and other are concerned that the advertisement mislead parents and other consumers.

    According to Engle, the claims are based on evidence that shows a strong correlation between working memory capacity (WMC) and general fluid intelligence.

    Working memory capacity refers to our ability to keep information either in mind or quickly retrievable, particularly in the presence of distraction. General fluid intelligence is the ability to infer relationships, do complex reasoning, and solve novel problems.

    The correlation between WMC and fluid intelligence has led some to surmise that increasing WMC should lead to an increase in both fluid intelligence, but assumes that the two constructs are the same thing, or that WMC is the basis for fluid intelligence, Engle said.

    In an experiment to validate the relationship between these two aspects of cognition, Engle and colleagues had 55 undergraduate students complete 20 days of training on certain cognitive tasks.

    The students were paid extra for improving their performance each day to ensure that they were engaged in the training.

    Students in the two experimental conditions trained on either complex span tasks, which have been consistently shown to be good measures of WMC, or simple span tasks.

    With the simple span tasks, the students were asked to recall items in the order they were presented; for complex span tasks, the students had to remember items while performing another task in between item presentations. A control group trained on a visual search task that, like the other tasks, became progressively harder each day.

    The researchers administered a battery of tests before and after training to gauge improvement and transfer of learning, including a variety of WMC measures and three measures of fluid intelligence.

    The results were clear: Only students who trained on complex span tasks showed transfer to other WMC tasks. None of the groups showed any training benefit on measures of fluid intelligence.

    we were surprised to see evidence that new and untrained measures of working memory capacity may be improved with training on complex span tasks. results suggest that the students improved in their ability to update and maintain information on multiple tasks as they switched between them, which could have important implications for real world multitasking:

    work affects nearly everyone living in the complex modern world, said Harrison, it particularly affects individuals that find themselves trying to do multiple tasks or rapidly switching between complex tasks, such as driving and talking on a cell phone, alternating between conversations with two different people, or cooking dinner and dealing with a crying child. the potential boost for multitasking, the benefits of training didn transfer to fluid intelligence. Engle points out that just because WMC and fluid intelligence are highly correlated doesn mean that they are the same:

    and weight in human beings are also strongly correlated but few reasonable people would assume that height and weight are the same variable, said Engle.

    they were, gaining weight would make you taller and losing weight would make you shorter those of us who gain and lose weight periodically can attest to the fact that that is not true. the debate continues, the investigators plan to continue this research to better understand how training specific aspects of cognition can lead to positive transfer to other tasks, both in the lab and in the real world.
