Playing memory games can improve other brain functions, such as attention, concentration, and focus. Memory games give space to critical thinking and that helps children nurture their attention to detail.
Memory games can improve visual recognition. With many memory games based on spotting differences, or linking two related images, children improve their visual discrimination. This will lead to an acceleration in distinguishing images from one and another.
Short-term memory is key to playing memory games and playing them often will improve function in this area. A good short-term memory can improve a persons long-term memory too. Both are linked and being able to move things from your short-term memory into long-term will improve learning in other areas.
