In 2010 the Jacobs Center on Lifelong Learning in Bremen, Germany, was commissioned to assess the impact of cognitive training for unemployed adults over the age of 50. After several cognitive training solutions had been evaluated, HAPPYneuron was chosen based on its effectiveness, easy handling and scientific background. Over a period of 3 months the voluntary participants took part in 3 training sessions of 45 minutes each per week. The results showed increased performances in the trained tasks as well as a transfer effect for certain tasks. The study mainly resulted in a major increase in self-confidence, thus also increasing participants' employability.
