The other factor is that of āfrustration closing the gates of learningā. After a few repetitions, the rate of acquisition decreases due to neural āoverloadingā (it takes time for new neural pathways to be madeā¦synapses, developing or being pruned). When you start fumbling and not making progress you become irritated and frustrated and this can directly inhibit the psychological process of learning. Thus when you feel this happening, you stop the repetitions, take a break and go and do something unrelated, perhaps before coming back to the task in hand.
Rate of rise of frustration and the time required away from the skill being learned will vary from person-to-person. When things donāt go the way I want, I get frustrated very quickly. When I was an undergraduate student, Iād plough forcefully through reading science papers thinking āI have to know thisā¦I must worker harder!ā It was counterproductive and I forgot most of the information. As a PhD candidate, I realised that I didnāt need to cram the detail in my head and read science papers almost casually, out in the park, on the bus, on the toilet (where I often do my best thinking) for fun and, ironically, the details stuck in my head of their own accord! I had disinhibited the retention of details by not being obsessed with their acquisition and frustrated by it.
Itās hard to ānot be botheredā and thus disinhibit your learning when you really love a subject, but thatās the paradox we have to live withā¦
