26 Feb Physiology of Learning to Generalize

Learning Cycle

I began this blog heavily concentrating on the physiology of the brain, its cells and the way they interconnect. Learning and association are not dealt with much in those posts other than to describe ways in which the brain and its cells provide mechanisms for these activities. Many of the mechanisms of association are fairly clearly understood […]

24 Feb Neural Network Perception

Speech Waves

Feedback in Image Processing While the flow of electrical impulses in the brain triggered by visual stimuli travels sequentially through layers I then II then III of the visual cortex, this directional flow does not prevent impulses from other sources, including feedback loops within the visual cortex from contributing to our ability to process images. […]

21 Feb Pattern Recognition in Two Dimensions

ANS Network

Perceptual Grid We live in three dimensional space, and understanding three dimensions is critical to our ability to go places and do things, but we comprehend things in many dimensions. Our senses, however, tend to flatten things out. Images are projected on our light-sensitive retinas in exactly two-dimensional patterns. The rods and cones possess light-sensitive […]

20 Feb Learning Cause and Effect

Cause and Effect Lightbulbs

Sparks of Kinesthesia When does a person begin to learn about the relationships between things that happen? Does the brain have an innate capacity to make the connections necessary to associate outcomes with catalysts? At what point does a person begin to learn that she or he can affect outcomes in the real world? One […]

17 Feb Call in the Reinforcements

Yin Yang

I think of learning like photography. The length of time of the exposure and the width of the aperture determine whether the film or digital array receives sufficient light to capture the image. The focus of the lens is important too. As adults, we can sometimes control the number of times we return to a […]

15 Feb Perceptual Signatures

Sound Signatures 3

We will momentarily leave Yorrick in his warm, cozy waterbed, to consider perceptual signatures that take place in the world outside him. This world is characterized by patterns, visual, audio, aromatic, tactile and complex, that each have their own signature.  The section of this blog on cognition, which deals with logic and reasoning, explores that […]

12 Feb Conscious Phenomena

Conscious or Psychic

Conscious Phenomena For the past few posts, I have been exploring consciousness. Extra-sensory perception is a part, or an extension of consciousness. Are you sometimes psychic?  Some people have truly remarkable extra-sensory capabilities while others do not. I read a short story by Ursula K. Le  Guin, though I can’t for the life of me remember the […]

11 Feb Conscious Sensibility

Spiderweb 1

Watergate Revisited More than one President of the United States has been asked this question: “What happened, and how soon did you know about it?” Many cognitive psychologists perform experiments in which they ask subjects (people) the same question, seeking to mark the boundaries between conscious and unconscious phenomena. I recently spoke of mindfulness. Wakefulness may be a […]

07 Feb Mindfulness

Attention Switch

Imagine being able to flip a switch and get quantitative and qualitative improvements to your intelligence. Mindfulness, in the form of directing your attention or focus can induce changes in the structure and function of the brain. When I was in school, I learned that taking notes helped me not only focus better on what I […]

04 Feb Body Language in Understanding

Body Language Examples

How much can you hear without a word being spoken? How often does something about a person’s face, posture or hand gestures completely contradict the “normal interpretation” of the words they speak, creating a sense of sarcasm or other indirect message? To what extent are the academy awards influenced by an actor’s ability to use […]
