We’ve all seen the ads for Lumosity, the Web-based service that boasts games that “train your bran”. You also have to pay to use Lumosity, something the ads don’t tell you. Well, I want to introduce you to a free and open source application that does the same thing and touches on exactly the same areas that Lumosity claims to address, but without the cost and fanfare. The application is gbrainy and we’re going to examine its components so you can see how it can help you train your brain.
First of all, you may wonder what are the components of gbrainy? gbrainy consists of four components: Logic puzzles which are designed to challenge your reasoning and thinking skills; Mental calculations, which measure your ability to mentally solve arithmetical calculations; Memory trainers are designed to test and improve your short-term memory; Verbal analogies assess your verbal aptitude.
Logic puzzles presents the user with a scenario and a question. Answers to questions can be both selected response and constructed response. The user can respond either by using the mouse, the keyboard or either one, depending upon the type of question. The puzzles measure users’ attention to detail as well as reasoning skills. So how do gbrainy’s Logic puzzles compare with Lumosity? Among the skills that Lumosity claims to promote are attention, speed of processing and flexibility. These games certainly help to cultivate these skills.
Mental calculations displays a mathematical equation to be solved by the user. The operations include common arithmetic operations, algebraic expressions, finding averages and working with decimals and fractions. The goal here is to determine the user’s ability to perform mental equations. gbrainy provides all of the data necessary to solve the problems. You need to provide the answers via keyboard or mouse. How does Mental calculations compare with Lumosty? They help to hone your speed of processing and problem-solving skills, just as Lumosity claims to do.
Memory trainers provides the user with objects to observe for a set period of time, then asks a question pertaining to what has been observed. These objects can be words, numbers or shapes and the amount of time to observe them is fixed. Input is given solely through the keyboard. For example,take a look at the Memory trainers screenshot to the right. After observing the numbers provided for the time allowed, gbrainy switched to a screen asking me how many odd numbers were listed on the previous screen. I actually found Memory trainers to be the most challenging of gbrainy’s puzzles due to the time factor. In comparison with Lumosity, Memory trainers matches it readily in terms of improving users’ short-term memory and their capacity to pay attention to details.
Verbal analogies assess and improve your vocabulary. The puzzles are all selected response. The user may be asked to choose the best definition for the word given from a list. Alternatively, the user may be asked to select a word that will best complete a given analogy. Additionally, gbrainy provides alternate answers that would have also been acceptable in addition to the answer provided by the user. This is a great opportunity to build your repertoire of synonyms. In terms of Lunosity’s goals, Verbal analogies strengthens both your long-term memory and your processing speed. The Verbal analogies screen is shown at left.
In closing, I just want to add that I did not write this to condemn Lumosity. I wrote this article to simply inform people that a free alternative is available. For more information, visit gbrainy’s Web site. gbrainy can also be played on the Web here.
