Three Key Elements Tested
The game randomly presents tasks involving visual counting (instantly counting shapes), text logic (identifying contradictions between a word's meaning and its position), and calculation speed (quickly solving simple addition and subtraction problems), requiring your brain to switch rapidly between different types of processing.
Cognitive Functions You Will Train
Training Processing Speed and Attentional Shifting
This game effectively trains processing speed (the ability to quickly recognize and make decisions based on information) and attentional shifting (the capacity to flexibly switch thinking between different rules) by requiring players to instantly select the correct answer while randomly cycling through diverse challenges—such as visual counting, text-based logic, and calculation speed. Furthermore, instances where the meaning of the text conflicts with its display orientation place a high demand on inhibitory control (the self-regulation required to suppress automatic reactions and adhere to the correct rule); these cognitive functions are closely linked to brain regions centered on the prefrontal cortex. Repeated practice is expected to enhance split-second decision-making and multitasking abilities, thereby helping to improve reaction times in daily tasks and while driving.
