1. Mental training and visualization captures many features of real-world behavior and perceptions.
2. Eye movements behind closed eyelids can indicate what a person is imagining.
3. Processing time is longer for small objects than for large objects in mental imagery.
4. Mental imagery is equivalent to real-world perception and behavior.
5. Deliberately moving your eyes in the direction of what you are visualizing can enhance the effectiveness of mental training and visualization.

- There are five principles of mental training and visualization that are well-established from scientific research literature.
- A systematic review of studies on motor imagery training elements in different disciplines found that brief, simple, and repeated visualization is effective, with 50-75 repetitions per session and 15-second rest periods.
- Mental training and visualization can increase the accuracy and frequency of real-world behaviors, but it is important to be able to successfully complete the behavior in the real world first.
- Performing mental training and visualization sessions 3-5 times per week is effective, and once a behavior is consolidated in the neural circuits, it does not need to be maintained with mental training and visualization.

- Real-world training is more effective than mental training, but mental training is more effective than no training.
- Mental training can help maintain or improve skills for those who are injured or unable to perform physical training.
- Combining real-world training with mental training can bring about greater results than either one alone.
- Adding even half an hour of mental training to 10 hours of real-world training can significantly improve performance.

- Building skills through physical and mental training requires focused attention and rest/sleep.
- Mental training can be done on the same day as physical training, but it's important to prioritize getting good sleep.
- Getting sufficient amounts of quality sleep is important for ensuring neuroplasticity occurs following both real-world and mental training.
- Sleep is critical for consolidating certain types of learning, especially motor skill acquisition and retention.
- A paper by Matthew Walker titled "Sleep and Timecourse of Motor Skill Learning" highlights the importance of sleep in consolidating motor learning.

- Sex differences in mental visualization and training have been explored, but subsequent studies show no significant differences between males and females.
- Age-related differences have also been explored, and for individuals 65 or older, a combination of physical and mental training may be more effective than physical training alone.
- For the majority of people, physical training is more effective than mental training, but a combination of both is even better as long as the mental training is on top of the maximum amount of physical training that one can do.
- Mental training is still more effective than no training at all.

- First-person mental training and visualization is generally more effective than third-person mental training and visualization.
- If what you're trying to learn doesn't lend itself well to first-person visualization, closing your eyes and trying to perform the task is effective.
- Watching videos of yourself doing a task can be effective, especially if you're trying to get better at public speaking.
- Brief and repeated mental training and visualization is key to building and consolidating skills.
- Real third-person visualization, where you're actually seeing and/or hearing yourself on a screen, is more effective than imagining yourself from a third-person perspective in your mind's eye.

- Mental training and visualization can be done with eyes open, not just closed.
- The cerebellum communicates with the primary motor cortex and can inhibit or activate it.
- Mental practice can enhance the net excitation of cerebellum to motor cortex communication, reducing inhibition and improving motor skill performance.
- A study showed that mental practice of a simple motor sequence improved speed and accuracy in the real world, and reduced inhibition in the cerebellum to motor cortex communication. 
- Mental training and visualization can improve motor skill performance, but require an ability to perform the specific motor sequence in the real world first.

- Motor sequences involve both a "go" action and a "withhold" action
- Mental training and visualization can improve both aspects of motor performance
- The basal ganglia are involved in go vs. no-go tasks and learning
- Restricting inappropriate movements or thoughts is a significant part of motor learning
- Mental training and visualization can improve the no-go aspect of motor learning.

- The stop signal task is a laboratory task that mimics action and cognitive learning in the real world.
- The task involves pressing keys in response to left or right-facing arrows, but also requires participants to withhold pressing a key when a stop signal is presented.
- A study found that a combination of physical and mental training improved response inhibition in the stop signal task more than physical or mental training alone.
- The study suggests that a combination of physical and mental training is especially important for learning to withhold inappropriate actions. 
- The training was performed five times over five days, and improvements were significant and occurred quickly.

1. Mental training and visualization have been studied since the late 1800s.
2. Neuroplasticity encompasses developmental plasticity and adult neuroplasticity.
3. Adult neuroplasticity is self-directed adaptive plasticity that can be directed towards specific desired learning.
4. Developmental plasticity occurs between birth and age 25 and is passive plasticity.
5. Self-directed adaptive plasticity can start in adolescence and allows individuals to decide what they want to learn.

- Aphantasia is a phenomenon where some people can't generate visual imagery.
- People with aphantasia can have varying degrees of the condition.
- Aphantasia is linked to weak visual imagery and features associated with the autism spectrum.
- There is a relationship between one's ability to generate visual imagery and certain constellations of cognitive and emotional perception and behavior.

- The podcast discussed the key components of effective mental training and visualization practice, including brief epochs and simple sequences of motor and cognitive behavior.
- Mental training and visualization should be repeated over time to improve plasticity of plasticity.
- Actual execution of specific movements and cognitive tasks in the real world is important for effective mental training and visualization.
- Mental training is a reasonable substitute for real-world training if unable to do so, but not a complete substitute.
- A combination of physical training and mental training is best for withholding action to get better at a skill.
- Mental training and visualization is effective for improving real-world performance, even with simple repeats three to five times per week.

- Learning requires focused, dedicated attention to trigger chemical and electrical processes in the brain.
- This attention may cause agitation and frustration, which is a normal signal that learning is happening.
- The second component required for learning is periods of deep rest, particularly a good night's sleep.
- Neuroplasticity, the rearrangement of connections between neurons, occurs during sleep, particularly on the first night following focused attention to learning.
- Second and third night effects can also contribute to learning if good sleep is achieved.

- Self-directed adaptive plasticity occurs when we learn and sleep well repeatedly.
- There are different forms of plasticity between neurons, including long-term potentiation and long-term depression.
- Long-term depression is not necessarily bad and can be excellent for learning motor skills.
- Long-term depression involves eliminating incorrect movements to arrive at only the correct movements in a reflexive and repeated way.
- Mental training and visualization protocols can capture both the potentiation and depression aspect of neuroplasticity and serve as a compliment to real-world cognitive and physical training.

- Mental training and visualization can activate the visual and auditory cortex in the brain.
- Most people can visualize simple stimuli like a yellow cube and a red rose, or a short musical motif.
- Long and elaborate visualizations are harder to imagine and repeat accurately.
- Mental training and visualization should be kept short and simple, lasting about 15-20 seconds, and repeated often for best results.
- People with aphantasia, or the inability to mentally visualize, may need to keep their visualizations even simpler and shorter.

- Mental visualization is studied by researchers such as Roger Shepard and Stephen Kosslyn.
- Shepard found that the time it takes to mentally visualize an object increases with its complexity, especially when rotating it.
- Kosslyn's experiment showed that the time it takes to mentally move from one location to another on a map is directly proportional to the physical distance between those locations.
- Mental visualization and real-world experiences activate the same neurons and have the same spatial relationships, but real-world experiences are more effective for learning and improving performance.

1. Mental training and visualization can be effective, but are most effective when combined with real-world training and experiences.
2. Bistable images and impossible figures are used in experiments to study visual perception.
3. It is impossible to imagine bistable images in our mind's eye, but we can do it if we trace or draw them first.
4. Mental training and visualization are more effective when combined with real-world behaviors and experiences that are similar. 
5. Mental training and visualization are not a replacement for real-world motor or cognitive training, but an addition that can help.

1. Assigning cognitive labels to mental training and visualization makes it more effective.
2. The human brain is exceptionally good at recognizing and processing faces.
3. Cognitive labels and accurate visualization are important for effective mental training and should match real-world experiences.
4. Naming and giving an identity to a real-world skill and applying the same name or identity to the mental version of that can enhance mental training and visualization.
