How to Actually Read Textbooks Effectively

“To be better equipped for the tests that the year will bring — read a textbook. To prepare for the tests that life will bring — read a book.”

Mokokoma Mokhonoana

Textbooks are not the same as the every day books that people read.

The Fundamentals of Chemical Engineering was a very different read than Man’s Search for Meaning. Textbooks require different methods of consumption. Since they’re are mostly filled with factual information that we are expected to understand and regurtitage, they can seem like a giant ball of chaos. This is a huge part of the reason why we don’t like reading them in the first place.

In my past blog posts, I talk extensively about the human mind and a multitude of theories describing how it works. A commonality in these posts and the writings of others I have read suggest that people are purpose oriented creatures. We need a clear purpose in front of us when we are reading textbooks. What stops people from reading textbooks is the ambiguous nature of it. Looking at a 1000+ page book with the intention of “learning everything” is too unclear and pushes us towards not doing anything at all.

We need a clear purpose when we are reading the books. This helps us articulate exactly what we are trying to learn. We can create purposeful and intentional reading by scanning the textbook before hand.

A Specific Method for Scanning Textbooks

This video is a fantastic resource for understanding efficient textbook consumption:

Here are some of the highlights from it.

Matt DiMaio suggests that students should flip through and scan each page so they can receive an overview on what is coming. This gives us our minds purpose when we flip through these pages.

We see unfamiliar images and phrases which will stick out to us as landmarks of recognition. The best way to maximize the results of method is to keep an eye out for things you don’t understand and lean into the questions that come to mind when we first see them.

Another key to reading textbooks efficiently is to skip to the End-Quiz. This lets us know exactly what to look for. Doing this right after an initial scan is the best time to read the end quiz questions because we have a small idea of what this chapter would be about, but we don’t know enough to know what to keep an eye out for. Reading the quiz before reading the actual chapter helps bridge this gap. Seeing the questions at the end provides a deeper level of articulation when it comes to our purpose when reading this chapter.

By this point, we should have two sets of questions bouncing around in our heads – one set that we created from our initial scan and the second are the questions at the end of the chapter.

If the chapter doesn’t have end of the chapter questions, there is most likely going to be a summary of the main points. These can also be turned into questions that could be answered. The idea is to keep developing questions that YOU genuinely want to know the answer to. This helps keeps our mind engaged when we are going through the text. There’s no substitute for genuine curiosity.

The next suggestion Matt DiMaio makes is to read the bold print because the information has already been broken down for you. The author(s) of the textbook (more often than not) layout the concepts in smaller chunks which usually come together to build a solid and thorough understanding of the overall concept. The bolded print keeps the information organized and are usually highlighting an important idea necessary for understanding the concept as a whole.

After, read the first and last sentence in a paragraph. The first sentence is usually an introduction and the last a conclusion. This is to get a quick, but slightly deeper understanding of the idea and it’s components. You get the jist of it but this point.

This method takes more time than just reading the chapter in one go, but it’s way more effective. During each of these stages, our brain is developing more and more questions which it will consciously and subconsciously look for. This helps us stay more engaged with the text, but is also in line with Active Recall, which is the most efficient learning method we currently accept.

Scanning doesn’t have to take more than 5 minutes and should be done before any intense reading happens. Students should almost never be reading textbooks cover to cover like we would novels. People are purpose driven creatures and firstly we need to know what we’re looking for. Scanning provides purpose when reading. Scanning a chapter multiple times will prime our brains perfectly for effective textbook consumption. Don’t shy away from repetition.

Repetition is the mother of learning.

3 Main Goals of Reading

Sometimes when I see people study for huge exams or quizzes, they will bust out their textbook and just start reading. Not only does this requires extreme amounts of cognitive load, but it’s also terribly ineffective. We are purpose driven creatures and just reading a textbook with the intention of “learning everything” is a slow moving trainwreck.

Here are 3 main goals we should keep in mind when we are reading textbooks:

1) Getting the correct information – we want to make sure we are reading the information that we are actually responsible for knowing. I can’t tell you how many test I’ve studied for that had completely different content than what I was studying. We want to know the right stuff.

2) Retaining that information – when we find this information, we want to make sure that we can remember it! We want to be able to remember it easily and over the long term, otherwise our efforts are wasted.

3) Spending less time – because honestly reading textbooks can be a drag and our time is usually better spent doing the things we’d rather do.

A Quick Tip on Goal Setting

These goals are assuming we agree with the fundamental axiom that there are ways to get better results with less effort. Now I can focus my energy on studying better, instead of trying to convince myself that there are better ways to read textbooks. I try to create goals with underlying assumptions that remove obstacles and push me forward. It’s a nice way of tricking our brain into getting things done.

Another example is what I do with these blog posts. My goal is to improve my blog posts at least 1% every week – that goal is created with the underlying assumption that I will be putting out a blog post every week. Now I’m not focused on just trying to get myself to write, that will come as a byproduct of focusing on improving the overall blog every week.

Methods to Test Comprehension

Reading textbooks out of order seems like a sure fire way to misunderstand the text. However, it’s actually more effective as long as we test our comprehension. Here are a few ways of testing yourself to make sure that you actually understand the key bits of information.

Answer all the Questions Included in the Chapter

Like I mentioned earlier, most textbook chapters have end of the chapter multiple choice quizzes. These are excellent active recall resources and a fantastic way to test your understanding of the key points.

Sometimes a textbook will include practice MCQs sprinkled throughout the chapter. This idea doesn’t just stop with multiple choice questions, they can apply to free response questions as well.

Write Out the Main Ideas in Your Own Words

Jordan Peterson said articulation is the deepest levels of understanding. First, we act out what we understand. The next level is thinking about what we understand. The deepest level is saying or writing it so another person can also understand the information. I should probably write a blog post on the different levels of understanding. When we write something down in our own words, we are forced to confront exactly what we know and what we don’t, which is a fantastic way of testing our understanding.

Evaluate When the Text was Published

The meaning in writing, no matter what kind, is nested in the words and pages of the text. But the text is also nested in its relation to everything else around it. The dominating thoughts of the times determine which ideas are presented and in what manner.

If the text is slightly outdated, it may fail to take into account new and precedent-breaking research. Questioning the text also key in testing understanding. Here are some questions you can start with:

Why are these ideas being presented in this order?

Is there anything included in the text that may have overlooked?

Questioning things naturally gives us deeper understandings. Shallow answers provide an opportunity to breed suffering and should rarely be accepted.

Summarize to Teach

This is a bite off the Feynman Technique. The idea is to summarize the material so a 5 year old can understand it. Try not to use any specialized jargon and address any questions that a 5 year old may ask when presented with the summary you write. When we teach, we put ourselves in the role of expert and our identity gets tied up with knowing the information thoroughly.

Explaining something at the level a 5 year old can understand is not a demonstration of simplified knowledge, but masterful understanding. True masters know what information to leave out so their pupil can best understand with their current frameworks of the world.

Practice Active Reading Over Passive Reading

I’m sure it seems like I’ve beaten this dead horse plenty, but I can’t stress this enough. Active Recall and Spaced Repetition are the two biggest pillars of studying less while learning more, and we would be foolish to not integrate that into how we read.

Instead of just reading line after line, we can engage with the text through the different methods of scanning outlined earlier or practicing these Methods to Test Comprehension. Keeping our brain active in the process, not only makes the learning more efficient, but keeps us interested and happy.

A good study session can be like being engaged in an enlightening conversation, it doesn’t have to be dull.

Determine the Focus

When you are reading it is important to know what kind of reading you will be doing. There are two main types of reading in this case, reading for main concepts or reading for details.

Are you reading to understand main concepts or details?

I recommend treating the main concepts like a framework for the big picture and the details as things we hang on the frame. Learn main concepts first, then fill in the blanks with the details.

Other Techniques for Effective Reading

A majority of these tips came from the notes I took while watching Marty Lobdell’s famous lecture on studying smart. You can watch the video for yourself here – but keep in mind, it’s an hour long.

If you don’t have time to check it out, don’t fret, I tried to include most of the value from this video in this blog post.

Do a Pomodoro Session, then Do Something Fun or Go Away

I talk about breaking up our work into smaller chunks all the time. Working for 25-30 minutes on a task, then walking away makes the task much easier to initiate. The reward makes us more likely to do it again! I go more in depth about the pomodoro technique and its modifications in this post. The main idea is to just break up the work into manageable time intervals. This is how I get all my blog posts done!

Reward Yourself After Finishing Your Entire Day

Do this not only because the reward is so much sweeter after finishing a day of work, but because it makes it easier for us to start again next time. If we know that we’re going to get a reward at the end, we can’t wait to get it done! Rewarding ourselves also solidifies all the newer neural pathways created in that session. Additionally, it prevents burnout and we ought to treat ourselves as people we are responsible for. If we committed a dog to a whole day of work, we would want to reward it afterwards for doing so well. We should give ourselves the same encouragement. We’ll die without it.

Study Concepts First, then Study Facts

I talk about this in my Strategies for Better Studying (Part 3) post and touched upon it earlier too. Studying just pure facts is impossibly difficult and we will never retain any information without tremendous effort. If we learn the concepts and understand how the facts fit into the bigger picture, then it is much easier to remember more facts with less effort. Create a framework of understanding, then hang the facts on the framework.

Highlight the Important Terms, but with Caution

I try not to highlight if possible. I layout some of the disadvantages to highlighting in [this post]. Highlighting triples our workload and increases the likelihood of focusing on lower yield information. If you find yourself in a situation where you must absolutely highlight, keep it at a minimum. Whatever is highlighted is considered important. When we highlight too much, we destroy prioritization. Not all information was made equal.

Our Brain is Better at Recognizing than Recalling

This is why Active Recall is such a powerful method of learning. The heightened difficulty of recalling information trains our brain more powerfully than simple recognition.

This is also why I suggest we scan our textbooks in the method laid out above. When we scan, we create points of recognition that allow us to hang the facts and intricate details of the information.

Flesh Out Notes to Solidify New Concepts

Right when we finish reading or get out of a lecture, we have an unstable understanding of the new concepts we’ve just learned. This is partly because we have very limited access to the information in terms of neural connections. With more neural connections, recalling specific information gets easier and easier.

Fleshing out our notes helps solidifies concepts in our mind, especially if they are a little fuzzy. The expansion gives us multiple neural points of connection, which allows for easier recall in the future. If fleshing the concepts out on your own is beyond your ZPD, I recommend comparing notes with a friend or discussing the topic with the professor in office hours.

Use Mnemonics to Memorize

Memorizing sucks and it’s nearly impossible to memorize random facts without connecting them to something else that we already understand. One of the best ways to memorize is to use mnemonics, little devices designed to help with remembering patterns or associations.

One version of a mnemonics are acronyms. Not to be confused with initialisms (which can be great mnemonics too), acronyms are words or names formed from the initial parts of a bigger name. NASA (National Aeronautics and Space Administration) is pronounced like a word, but stands for a larger name.

One of my favorite acronyms are used for remembering the colors of a rainbow – ROY G. BIV. It sounds like the name of a man, but it stands for red, orange, yellow, green, blue, indego, and violet.

Another type of mnemonic devices are coined sayings. These are crazy phrases used similarly to acronyms. One of my favorite coined sayings is for memorizing the Krebs Cycle intermediates is “Can I Keep Selling Sex for Money Officer?”

C – citrate I – isocitrate K – a-ketoglutarate S – succinyl CoA S – succinate F – fumarate M – malate O – oxaloacetate

It’s easy to remember because it’s about sex. The more sexual, vulgar, and ridiculous are, the easier they are to remember. So don’t be afraid to get a little crazy.

The last type of mnemonic that I’m going to talk about here are image associations. Some people also refer to this as the “Mental Mind Palace” or the “method of loci.” The main idea is to picture a place that we are extremely familiar with, like our home for example, and place the different bits of information in places across your house.

This sounds a little woowoo, but the core of this method is to connect our familiar environment as triggers of recognition to the information that we want to memorize. This works wonders for some people and not so well for others. I wouldn’t recommend this method over the other ones, but what is powerful is knowing that we can associate any information we want with images.

Using images to solidify a concept in our minds is powerful because the human brain is mainly designed to function around sight. We are relatively visual creatures and using visualization to enhance memory is like a cheat code. Similar to coin sayings, the more sexual, vulgar, and ridiculous the image is, the easier is will be to remember.


Reading is like working out. It takes time to get better at it. Reading a textbook is like learning how to work out a specific part of your body. Stick with it. All principles regarding skill building also apply here too, so things like The Valley of Disappointment, The Transition Curve, and The 20 Hour Rule are also at play. See each reading session as a practice in developing the “textbook reading” skill.

The Brain vs. The Mind (Part 2)

“The mind is its own place, and in itself can make a heaven of hell, a hell of heaven.”

John Milton (1608 – 1674)

The Mind

The mind what makes us feel alive and aware. It gives us the faculty of consciousness and the ability to think. The mind provides us with judgement, perception, language and memory. People all throughout time have dedicated their entire lives to trying to understand the mind but there is no shortage of things we don’t understand. Some of the people that studied the mind in depth include but are not limited to: Aristotle, Plato, Seneca, Descartes, Locke, Hume, Kant, Schopenhauer, Nietzsche, Freud, Jung, Peterson, and many, many more. The mind is a strange place that we know very little about, but we can use what little we do know to our advantage. For some, the mind is the enemy. Perhaps it’s the most formidable enemy we’ll ever meet, but learning a few things about our minds can turn it into our most valuable ally.

I’ll do a brief run through a few of the topics that are integral to understanding the mind. Each of these topics is extremely dense and you can spend your entire life learning about just one aspect, but knowing just a little bit can make a dramatic difference in our lifestyle.

Mental Faculties

Thought

Wikipedia puts it best when it comes to summarizing what thinking is – “Thinking is sometimes described as a “higher” cognitive function and the analysis of thinking processes is a part of cognitive psychology. It is also deeply connected with our capacity to make and use tools; to understand cause and effect; to recognize patterns of significance; to comprehend and disclose unique contexts of experience or activity; and to respond to the world in a meaningful way.”

There are many theories to how the mind works. One of my favorites are diffuse thinking vs. focused thinking:

Focused thinking is what we traditionally think of when we hear the word thinking. It’s effortful, deliberate, and concentrated. It’s what we use when we’re consciously trying to solve a problem. Focused thinking eliminates distractions and gets the job done through sheer will power. This type of thinking is made possible through the contributions made by the prefrontal cortex. Focused thinking is optimal when you have high energy and the solution to the problem is right outside your zone of proximal development.

On the other hand, diffuse thinking is less straightforward. Diffuse thinking is the kind of thinking that’s running in the background making connections without you consciously noticing. Diffuse thinking occurs when we’re doing mundane tasks or whenever our brain has the ability to “wonder off.” Unlike focused thinking, diffuse thinking occurs in all parts of the brain. The freedom the brian has to make random connections allows for more creative solutions to come about. Diffuse thinking is optimal for when you are presented with a problem that may need a creative solution that you can’t immediately see. Benjamin Franklin used to induce diffuse thinking with his special napping technique whenever he came across a problem that he didn’t know how to solve.

Daniel Kahneman wrote about another thinking dichotomy in his best selling book, Thinking, Fast and Slow. In this book, he discusses the brain working in two gears but he calls them System 1 and System 2. It’s similar to focused thinking vs. diffuse thinking but with some nuances. The main idea is to use System 1 to get the easy things done, but to slow down and use System 2 when necessary. Many people tend to mix these up and make important decisions quickly resulting in many unnecessary problems. I recommend checking his book out!

Thinking, Fast and Slow – Daniel Kahneman
Memory

Memory refers to our ability to keep and retrieve information. The study of memory has been a meeting point of several different academic disciplines such as neuroscience, psychology, philosophy, and biology. There are many different kinds of memory. I laid out working memory vs. long term memory in my last post, but there are a few others that are worth mentioning.

Long Term Memory

It’s an umbrella term and splits into two different kinds of long term memory – Declarative and Implicit Memory.

Declarative (Explicit) Memory is the conscious and intentional storage of facts, events, and concepts. This is the memory that’s consolidated during stage 3 of the sleep cycle. Declarative memory can also split into two types:

Episodic memory refers to our autobiographical memory of specific events. It’s basically our collection of how we remember our life events.

Semantic memory refers to our memory of words, concepts, numbers, or other general worldly knowledge that we may need to survive. This type of memory is dependent on culture and experience.

Implicit Memory is the unconscious and unintentional learning that affects our thoughts and behaviors. Implicit memory is the reason why priming is a popular marketing method advertisers use to sell their products.

Procedural Memory is the best example of implicit memory at work. Procedural memory is responsible for knowing how to do things and it’s consolidated during the REM stage in the sleep cycle. This part of our memory picks up on the motor skills necessary to make every day life easier. This is how we learn how to talk, walk, ride a bike, play an instrument, etc.

Memory Tree (2019)

Retrieval

Part of what we consider to be our memory is our ability to access the information stored in our brains. The two main methods of retrieval are recall and recognition.

Recall

Recall refers to our ability to retrieve information from our long term memory with little or no cues.

Recognition

Recognition refers to our ability to retrieve information from our long term memory because of specific cues.

Imagination

“Scientists must have a vivid intuitive imagination, for new ideas are not generated by deduction, but by an artistically creative imagination.”

Max Planck (1858 – 1947)

Scientists aren’t the only people who must have imagination, it’s necessary for everyone.

The imagination has been described as a subjective process that the mind uses to perceives the world and the activity of creating new situations, concepts, images, or any other qualia. Even when setting aside the make-believe games that children need to play, people use their imagination all the time. Whenever we think of possible future scenarios, see things from other people’s perspectives, or get lost in a daydream we are using our imagination. Imagination is crucial for problem solving, especially under restricted conditions, so there are many practical reasons to develop our imagination. I say imagination is the fuel for creativity, and our creativity is what separates us from animals. We should lean into our imaginative thoughts. Everything we have around us was first imagined in someone’s mind. Everything.

Developing our imagination is key to solving all of our world’s biggest problems. Climate change will be solved through imagination. The social and political conflicts around the world will end through new solutions that have not been implemented (or maybe even thought of) yet. Imagination solves problems. Imagination creates life.

Assimilation & Accommodation

Assimilation, according to Swiss developmental psychologist Jean Piaget, is using an existing schemata to make sense of a new situation. It’s the first step in learning something new! Whenever we encounter something new, we first try to relate the novel stimuli to something we already know in hopes of understanding it well enough to deal with it. For example, whenever I’m teaching my students how to solve algebraic inequalities, I show them how it’s similar to solving regular algebraic equations.

Accommodation is what we use when we don’t have the necessary schemas to perceive the new information. If the new information still doesn’t make sense even after applying our pre-existing schemas, then we modify existing schemas or create new ones to accommodate for that new information. This is how we learn new things. We build new knowledge on top of the knowledge we had before when we encounter new circumstances.

Identity

“Every action you take is a vote for the type of person you wish to become. No single instance will transform your beliefs, but as the votes build up, so does the evidence of your new identity.”

James Clear

Our identity is how we see ourselves and how we know who we are. Over the course of our lives we create this person based on our interpretations of our life events or our goals we set for ourselves. This is arguably the MOST powerful force that motivates us. Our habits and choices are based off what kind of person we see ourselves as.

What makes our identity such a powerful force?

Identity Defense is how we preserve who we think we are. This results in rejecting actions that don’t match with who we think we are and continuing actions that match who we think we are. We love being right and hate being wrong, and nothing is worse than being wrong about who we think we are. The kind of person that we see ourselves to be is the one thing that we like to think we know for sure. This is powerful in creating new habits and explains why starting new habits could be difficult. New habits may not be seen as something that would match up with our current view of ourselves so in order to be right about who we are, we reject the idea of doing those actions.

If we see ourselves as athletes, then we are more likely to do what athletes do.

If we see ourselves as musicians, then we are more likely to do what musicians do.

If we see ourselves as great students, then we are more likely to do what great students do.

If we see ourselves already as the people we desire to be, then taking on the new actions won’t feel so strange. Be the new person, everything else will follow.

The Self

Our identity is very much aligned with how we know ourselves. When we say I know myself, what does that actually mean? We have multiple ideas of our self and these ideas play into how we form our identity.

All of the multidimensional ways we describe ourselves is known as our Self-Concept. It transcends time and applies to our past, present, and future self. We have infinitely many ways in which we describe ourselves, but it’ll just cover a few of them here –

Let’s start with our Actual Self. This is who we are in reality; it includes all of our strengths, weaknesses, and how we know ourselves to act in the world. It’s tough to get an accurate read on who we are objectively, but with serious reflection and the right team of people around us we can find our actual limits and use that knowledge to our advantage.

The Ideal Self is the person who we strive to be. This is can be seen as analogous to Freud’s Superego. This is the version of ourselves that judges us when we make a mistake and praises us when we act in alignment with it. This is the self that most people identify with the most. It’s easy to mix up the actual self with the ideal self.

The Ought Self is the person who other people want us to be. Sometimes the person we think we should we is the person that other people think we should be. We should recognize when this is the case and act in accordance with our own commitment to our Ideal Self. I’m not saying we should never let other people influence how we act, I’m suggesting that it’s extremely beneficial to recognize the affect other people have on our sense of self and decide if it’s worth internalizing.

Our Self-Esteem is our evaluation of ourselves in relationship to our ideal self. The closer our actual self is to our ideal self, the higher our self-esteem. The further our actual self is to our ideal self, the lower our-self esteem. The best way to raise your self-esteem is to clearly define what your ideal self is and do actions that coincide with the your ideal self.

Self-esteem is not the same as Self-Efficacy, which is how capable we think we are at a given skill or situation.

Our self-efficacy is what drives the idea that we have to learn a certain way (like visual or auditory) or that we are only skilled in certain subjects (“I am a math person” or “I am an English person”). That isn’t true. Our self-efficacy can be improved and with those improvements comes a higher rate of learning in all domains of life, higher self confidence, and exciting opportunities!

We can improve our self-efficacy in three steps:

  1. Making & accomplishing small attainable goals
  2. Recognizing those small accomplishments as significant and the preferred method of progress, as opposed to working hard for one large accomplishment
  3. Slowly increasing difficulty over time

If we don’t take care of our self-efficacy, it’ll be difficult to try new things and eventually one could slide into the realm of Learned Helplessness. This is one of the lowest forms of diminished self-efficacy. It comes about from being in consistently hopeless scenarios. Sometimes there are things we can’t do, and if we find ourselves in those situations enough then we’ll learn that there isn’t anything we can do anywhere.

Learned helplessness is serious, but can be avoided. Recovering from learned helplessness requires a shift in identity, recognizing our cognitive biases (specifically the negative ones we hold about ourselves), setting them aside, and focusing on raising our self-efficacy.

One noteworthy mention is Carl Jung’s definition of The Self. I reference this in my other post The Power of Failure. Jung believed that the Self was developed through individuation, which is the integration of your personality. The Self is the representation of the unification of our conscious and unconscious. It’s my understanding that the primary means of individuation is through circumambulation, which is also mentioned in The Power of Failure.

There are many ways to define ourselves, so no one way is objectively true. But one thing is certain, understanding how we see ourselves is crucial to improving and getting out of our own way.

Dramaturgy (Front Stage Self vs. Back Stage Self)

Front Stage Self

This is the self which we present to other people. The self we put out to fit the social norms.

Back Stage Self

This is the self that we are when we are not around other people. This self is the one that really runs the show. Most of the actions that define our lives and self-concept are driven by the back stage self.

Collapsing these two as much as possible will make success in any domain easier. We don’t have to completely merge them together, but an honest life keeps us confident and directly affects our self esteem and efficacy. Training the back stage self to be well polished and pristine like our front stage self will allow us to accomplish what we need to accomplish to reach our goals.

Cognitive Load

I like to think of cognitive load as our brain’s biological RAM or our mental gas tank. In the morning (if we’re well rested) we start off with our full processing capacity, but as the day goes on every little task and decision chips away at our cognitive load until we go to sleep. Not all activities require the same amount of cognitive processing. Multitasking or activities that require intense concentration use up our cognitive load the most. This is why I do the most difficult tasks first – just getting my lazy ass to do it is going to take tons of cognitive load, so to speak. I won’t have the physiological brain power necessary to do the difficult tasks well if I save them for the end of the day.

Maximize bandwidth by reducing cognitive load.

Scientifically Proven Ways to Reduce Cognitive Load

  • Apply Occam’s razor to everything
  • Minimize the number of decisions you make per day
  • Remove needless words
  • Do the most difficult tasks first
  • Collaborate
  • Use cognitive aids (e.g. checklists, calendars, notifications)

Top-down Processing vs. Bottom-up Processing

Examine the following sentence – Rocky loves to rock on his rcoking chair to rock music.

Noticing that the c and the o in rocking chair are reversed is a form of bottom-up processing, seeing each letter and concluding that it is supposed to say rocking. But knowing that rcoking and rocking are similar for all intents and purposes is a form of top-down processing because you have noticed that the word is rocking then noticing later that the letters are switched.

Top-down Processing

Our ability to perceive something and apply what we already know and expect to perceive details that match with our conclusions.

Bottom-up Processing

Our ability to perceive a collection of details as they come and conclude what something is as a result of those details.

How does it relate to studying?

When studying, we want to use bottom-up processing to fight against our top-down processing tendencies. It’s easy to review a topic and think we know all the small details because we are familiar with hearing the name of the chapter or section, but in reality, we need to practice our concepts from the small details up and practice working through everything to really make sure that we know our information.

To study through bottom-up processing, doing practice problems or answering free response questions will help identify any gaps in your knowledge when it comes to the concepts you are responsible for learning. This type of studying is also know as Active Recall.

How do both processes work for us and against us?

When studying, it’s easy to fall into the trap of top-down processing. If we study simply by looking over our notes or reading quick sections over the chapter, we’ll be at a loss when the test comes and that will have a negative impact on our grades.

However, this doesn’t mean that top-down processing doesn’t have it’s uses. Sometimes top-down can be great for trying to learn something new. Applying top-down processing to a new concept can help you try to see the bigger picture then fill in the smaller details later. This is something I like to call Knowledge Frames. Building knowledge frames is perfect for frontloading, or previewing new information in advanced in order to focus on reviewing rather accommodation or assimilation. When I was in EMT school, I used knowledge frames to learn the blood flow through the heart in less than 10 minutes!

Bottom-up processing is great for reviewing content and can prevent us from deluding ourselves from thinking that we understand something when we actually don’t. I have had plenty of experience using bottom-up processing while studying and taking tests I was grossly underprepared for.

That being said, bottom-up processing isn’t so great for learning new material. Using bottom-up can create an illusion of new concepts seeming more difficult than they actually are. Purely memorizing individual facts or ideas about a new concept without trying to find how they all fit together will make any class 10x harder than it should be.

Both have their place and being aware of their existence can give us more firepower when dealing with a new class of information. Experiment with both and find your own methods that can maximize your results.


We interact with the world on many different levels. When a snake lunges towards us, we jump back before we consciously realize that the snake is attacking us. Our bodies are interpreting the world at one level and our minds interpret the world on another. Understanding our minds, is understanding part of how we interact with the world around us which will help us in anything we pursue. This is why I consider understanding our brain and mind important and treat it as a metaskill and I highly recommend diving into the fields of psychology, philosophy, neuroscience, and literature if you’re interested in doing so.

Despite this blog post and the much larger body of work other people much smarter than me have put together, there is no shortage of things we don’t understand about the mind.
