Learning, Transfer And Working Memory

Practice makes perfect, but a question that still remains a mystery is why it is so difficult to transfer learning from a trained to an untrained task? Why are we no better at remembering faces when we have been training our memory for words? Scientists at Umeå University and Karolinska Institutet in Sweden now show in the journal Science that the answer lies in the brain areas activated by each task. The scientists studied the brain activity of healthy subjects as they performed a task that was part of a training program and two untrained tasks. Their performance on the trained task and one of the untrained tasks improved. What these two tasks had in common was the activation of the striatum, a cluster of neuronal nuclei in midbrain. read more
