The power of Learning




Our knowledge-based economy depends on talent, innovation, ingenuity, and hard work. Intellectual capital is becoming the central pillar of society. Technological progress and social change highlight also the need for a diversity of talents. The notable discovery of our generation is that intelligence can be actively improved, This heightens our responsibility to be up-to-date in our fields, to discover and nurture our talents. Respect for individual abilities is nowhere more apparent than in the celebrity culture, whether in film, politics, arts, sports, and science. A college degree is often a requirement for a job, but it is not required for creating a successful life. Nor does a college degree end your need for learning; to stay current requires curiosity and drive toward mental growth.

COPYING  Copying, which requires a trusting environment, is the first learning method of children. People who agree imitate each other’s mannerisms and even posture, making copying the most efficient way to acquire knowledge and new skills for adults as well. Even without awareness, it facilitates the familiarization of new material, situations, and organizations.
Positive relationships build social capital. Through mentoring and copying, employees can absorb the culture and the non-written rules of the organization. Gradually building confidence in this way positions you for administrative understanding and leadership. Copying healthy emotional performance can make significant advancement in personal well-being. 

LEARNING AND THE MIND  Education is an active process to improve a skill or knowledge. Two consecutive stages appear to make up learning. Gathering and absorbing the material is the first stressful and confusing stage, which seems to be essential to conceptualize the information. The challenging phase gives way to the integration of the content; an expanding and positive experience generates order and meaning.

My straightforward handbook, The Power of Joy, gives you the tools and advice you need to liberate yourself from your negativity and become the best version of yourself. Now you can find it on Amazon.

The neural representation of a flexible Working Memory Model




Working memory has a limited capacity to hold information short term. For example, humans and monkeys can maintain 3 or 4 objects at once. Working memory is fundamental to everyday function; we can produce a complex sequence of behavior, reason, plan, and create. It is essential in intelligent decision-making. 

Recent work by Bouchacourt and Buschman suggests a flexible model of working memory, where a well-organized sensory layer connects to a random and unstructured layer of neurons. Random recurrent connections generate persistent activity that can represent any arbitrary input. When the random links overlap, representations interfere, which limits the memory capacity of the network. Sufficient recurrent activity between the sensory and random networks form feedforward-feedback loops. The product of the feedforward-feedback weights can be changed up to ∼5% without significant loss of function.
During unsupervised learning, inhibitory interneurons spread inhibition across the population of so-called pyramidal neurons. Such a structure represents high plasticity, which reflects the statistics of the real world, embedding knowledge about how stimuli relate to one another. 
The model expresses both the flexibility and the limited capacity of working memory.
