Overview of <\/strong>Peak Mind<\/em><\/strong> by Amishi Jha<\/strong><\/h2>\n\n\n\n

Your ability to pay attention impacts every aspect of your life\u2014from how well you perform at work to how deeply you connect with others<\/a>. Yet it\u2019s often difficult to focus on what matters<\/a>.<\/p>\n\n\n\n

In her book Peak Mind<\/em><\/a>, neuroscientist Amishi Jha suggests that this struggle to pay attention prevents your mind from functioning at its peak, resulting in poorer decisions, forgotten information, and emotional instability. She argues that practicing mindfulness can help you overcome these challenges, improve your ability to pay attention, and enhance your overall mental functioning<\/strong>.<\/p>\n\n\n\n

Jha is a professor of psychology and Director of Contemplative Neuroscience at the University of Miami, where she leads research on attention, mindfulness, and resilience. Her research has been funded by the US Department of Defense and has led to mindfulness training programs for the military, first responders, corporate leaders, and elite athletes. She\u2019s published extensively in peer-reviewed journals, and her research has been featured in The New York Times<\/em>, Scientific American<\/em>, and TIME<\/em>. <\/p>\n\n\n\n

Part 1: What Is Attention?<\/strong><\/h3>\n\n\n\n

Jha describes attention<\/a> as your brain\u2019s manager, controlling how you perceive, interpret, and respond in every moment of your life. It does this by determining what information your brain notices, processes, and remembers<\/strong>\u2014which in turn, influences your thoughts, feelings, decisions, and behaviors. According to Jha, attention controls what information your brain notices and processes through three interconnected subsystems:<\/p>\n\n\n\n

1) The orienting system<\/strong> narrows in on specific information and suppresses distractions, helping you focus on a single subject. For example, while cooking dinner, this system helps you concentrate on chopping vegetables rather than your buzzing phone.  <\/p>\n\n\n\n

2) The alerting system<\/strong> maintains broad awareness of your environment, helping you scan for new stimuli and stay vigilant. For example, this system helps you stay mindful of the water boiling on the stove to avoid spillover. <\/p>\n\n\n\n

3) The executive system<\/strong> juggles your goals and priorities<\/a>, helping you plan, prioritize tasks, and solve problems. For example, this system helps you coordinate multiple steps\u2014saut\u00e9ing vegetables, preparing side dishes, and setting the table\u2014to get dinner prepared on time.<\/p>\n\n\n\n

Jha explains that these three subsystems share a single pool of mental resources, so<\/strong> they can\u2019t all run at peak capacity simultaneously<\/strong>\u2014when one ramps up, another steps back. For example, if your orienting system locks onto finely chopping onions, you might not notice that the water is about to boil over (alerting), or you might forget to season your vegetables (executive). <\/p>\n\n\n\n

Part 2: How Attention Impacts You<\/strong><\/h3>\n\n\n\n

Now that you know what attention is and how it controls what information you notice, let\u2019s look at how attention interacts with working memory<\/a><\/em> to help you function in all aspects of your life. Then, we\u2019ll explain how scattered <\/em>attention disrupts this interaction and creates a variety of problems in your life.<\/p>\n\n\n\n

Attention Interacts With Working Memory to Help You Function<\/strong><\/h4>\n\n\n\n

Jha defines your working memory as a temporary mental space where your mind manipulates the information it\u2019s actively processing, which allows you to learn, plan, and solve problems in short bursts. She explains that working memory and attention are interlinked\u2014they interact to help you process tasks, form long-term memories, and regulate emotions.<\/strong> Let\u2019s explore each of these functions in detail.<\/p>\n\n\n\n

Function 1: Processing Tasks<\/h5>\n\n\n\n

Jha explains that when you focus your attention on something\u2014whether it\u2019s a fact you\u2019re learning, a sensory experience, or a conversation\u2014information relevant to that task enters your working memory. It must remain in your working memory for you to manipulate and process it, and thus to complete your task. It can be difficult to keep this information in your working memory, though, because working memory can only hold about three or four pieces of information at a time, and only for as long as you keep your attention on them. Thus, it\u2019s crucial that you can control your attention and keep it focused on the information in your working memory, because if your attention strays, other information will enter your working memory and replace the information related to your task. You\u2019ll then struggle to process the task.<\/p>\n\n\n\n

For example, to calculate a sum in your head, you first need to focus your attention on the relevant numbers to get them into your working memory. Then, you need to keep focusing on those numbers so that they stay in your working memory long enough to do the math. If you switch your attention to something else\u2014for example, to a conversation near you\u2014the math numbers will get knocked out of your working memory, replaced by information from the conversation before you can complete the calculation.<\/p>\n\n\n\n

Function 2: Forming Long-Term Memories<\/h5>\n\n\n\n

In addition to helping process tasks, attention interacts with working memory to form long-term memories. According to Jha, working memory is a portal through which information must first pass to be stored as a long-term memory<\/strong>. The process works like this:<\/p>\n\n\n\n

    \n
  1. As previously explained, focusing on something allows information to enter your working memory. Then, maintaining focus<\/a> on that information keeps it active<\/em> in your working memory. <\/li>\n\n\n\n
  2. During this active time, your brain processes the information, forming new neural pathways<\/a> to store it as a long-term memory. The longer the information remains in your working memory, the more time your brain has to complete this process.<\/li>\n<\/ol>\n\n\n\n

    Jha argues that your brain can only convert information into a long-term memory if you hold it long enough\u2014by maintaining focus on it\u2014in your working memory<\/strong>. Otherwise, information passes through your working memory too quickly to leave any lasting trace. This explains why you might not remember things that you were physically\u2014but not mentally\u2014present for: You can\u2019t memorize something you never fully focused on in the first place. <\/p>\n\n\n\n

    Function 3: Regulating Emotions<\/h5>\n\n\n\n

    According to Jha, attention also interacts with working memory to regulate emotions. She explains that working memory is where you experience and process moment-by-moment emotions<\/strong>. As already established, attention determines which information enters working memory\u2014this information includes any emotional stimuli you choose to focus on. And as with other stimuli, sustaining attention on an emotional stimulus keeps it active in working memory.<\/p>\n\n\n\n

    Jha explains that when you maintain focus<\/a> on an emotion, it increases the emotion\u2019s intensity and prolongs its duration<\/strong>, raising the likelihood that it will drive your behavior or reactions\u2014which then makes you feel that emotion even more. For example, imagine you feel frustrated by a harsh email from your boss. If you re-read the email and dwell on your boss\u2019s words, your feeling of frustration will stay active in your working memory and thus intensify. As a result, you\u2019ll be more likely to fire off an impulsive response or carry that irritation into your next interaction\u2014which will further magnify your frustration.<\/p>\n\n\n\n

    On the other hand, if you shift your attention elsewhere, the emotion fades from your working memory. This reduces how strongly you feel it, lowering the chance that it will dictate your actions or continue to affect you<\/strong>. For example, if you turn your attention to another email or task, your frustration loses its hold on your working memory. As a result, you feel less aggravated and gain the clarity to respond in a more measured, constructive way.<\/p>\n\n\n\n

    Scattered Attention Creates Six Negative Effects<\/strong><\/h4>\n\n\n\n

    As we just discussed, when attention and working memory interact appropriately, they help you function well. But what happens when your attention is scattered<\/em>\u2014that is, when you can\u2019t maintain focus as needed? According to Jha, scattered attention negatively impacts your life in six ways\u2014let\u2019s explore each.<\/p>\n\n\n\n

    Negative Effect 1: Distorted Perceptions<\/h5>\n\n\n\n

    The first way<\/a> scattered attention negatively impacts you is by distorting your perceptions. Jha explains that whatever information occupies your working memory shapes both what you notice in your environment and how you interpret that information<\/strong>. Because your attention subsystems determine which details reach working memory, letting attention slip means you collect only fragments of what\u2019s happening. Taken out of the full context of your situation, these fragments can lead you to misinterpret new information.<\/p>\n\n\n\n

    Further, since working memory can only hold three or four pieces of information at a time, scattered attention may allow irrelevant information to take up this limited space, preventing working memory from fully processing the most important details for understanding your environment. This can lead you to piece together incomplete data, arriving at skewed conclusions that distort your view of reality. For example, while checking emails during a meeting, you might miss key parts of what’s being said but catch fragments about project delays, leading you to incorrectly conclude the discussion was mostly negative.<\/p>\n\n\n\n

    Negative Effect 2: Diminished Present-Moment Awareness<\/a><\/p>\n\n\n\n

    In addition to leading you to gather and interpret incomplete details\u2014thus distorting how you see things\u2014scattered attention prevents you from fully experiencing each moment. Jha explains that your attention subsystems feed real-time input into your working memory to create a complete picture of the present moment. When your mind drifts, these subsystems fail to deliver that ongoing stream of information. As a result, large portions of the present slip by without ever being processed<\/strong>, weakening your sense of connection<\/a> to what\u2019s unfolding. Over time, these gaps accumulate, leaving you feeling as though life is passing you by.<\/p>\n\n\n\n

    Negative Effect 3: Impaired Learning and Memory Formation<\/h5>\n\n\n\n

    Jha argues that, in addition to leading you to misinterpret or miss information, scattered attention impairs both learning and memory formation<\/a><\/strong>. As previously explained, your brain can only convert information into stored knowledge or memories if you hold it long enough in your working memory. When your attention is scattered, working memory cycles through bits of information quickly, preventing important details from getting the sustained attention they need. As a result, you don\u2019t fully grasp or retain new information, and instead of storing clear facts or forming vivid memories, you\u2019re left with fragments that are harder to recall when you need them.<\/p>\n\n\n\n

    For example, trying to memorize a phone number while simultaneously scrolling through social media prevents you from focusing on the whole number long enough to commit it to memory. As a result, you might only remember a few disorganized digits.<\/p>\n\n\n\n

    Negative Effect 4: Weakened Executive Functioning<\/h5>\n\n\n\n

    Jha explains that distorted perceptions<\/a>, missed moments, and fragmented learning can leave you with irrelevant information in working memory, impeding your ability to make decisions and coordinate tasks. This is because your executive subsystem depends on clear input from your orienting and alerting systems to weigh choices and plan action steps\u2014an ability known as executive functioning<\/em>. <\/p>\n\n\n\n

    When your attention is scattered, working memory becomes clogged with details that don\u2019t matter, leaving minimal space for the facts you need to assess options or juggle multiple tasks<\/strong>. This lack of relevant input disrupts your ability to logically plan and carry out the sequential steps involved in complex tasks\u2014resulting in uninformed decisions and ineffective task management. In other words, your overall executive functioning suffers.<\/p>\n\n\n\n

    For example, suppose you\u2019re planning a trip, which involves comparing flight times, coordinating hotel check-ins, and managing visa requirements, but you keep getting distracted by text messages. As irrelevant details occupy your working memory, you might forget to account for a layover, overlook time zone differences, or double-book accommodations\u2014ultimately derailing the entire itinerary.<\/p>\n\n\n\n

    Negative Effect 5: Emotional Imbalance<\/h5>\n\n\n\n

    The fifth way scattered attention negatively impacts you is by creating emotional imbalance. It does this by disrupting how you process <\/strong>uncomfortable<\/em><\/strong> feelings in working memory<\/strong>. As previously explained, Jha says that attention determines which emotions enter working memory and how long they stay there. Keeping attention on an uncomfortable emotion re-feeds that feeling into your limited-capacity working memory, intensifying it and crowding out other information you might want or need to focus on. <\/p>\n\n\n\n

    On the other hand, withdrawing attention from an uncomfortable emotion prevents you from fully registering and resolving it, allowing it to linger dormant and potentially erupt later. By swinging between these extremes\u2014over-focusing on or denying uncomfortable emotions\u2014you destabilize your emotional balance,<\/strong> making it harder to stay composed, think clearly, and respond thoughtfully in everyday interactions.<\/p>\n\n\n\n

    Negative Effect 6: Ineffective Communication<\/h5>\n\n\n\n

    The sixth way scattered attention negatively impacts you is by hindering your ability to communicate effectively. Jha explains that to interact and relate well with others, your orienting system needs to pick up on specific social signals\u2014like words, tone, and body language\u2014while your alerting system remains aware of a conversation\u2019s broader context. When you don\u2019t pay attention, these subsystems can\u2019t supply working memory with the complete picture, causing you to overlook important nuances, misread people\u2019s intentions, and respond based on inaccurate impressions<\/strong>. These lapses make it difficult to truly understand and empathize with others\u2019 perspectives, preventing you from connecting meaningfully with them.<\/p>\n\n\n\n

    Part 3: Why Common Attention-Management Strategies Don\u2019t Work<\/strong><\/h3>\n\n\n\n

    We\u2019ve now explained how attention interacts with working memory and why scattered attention creates problems in your life. You may have tried to solve these problems by implementing three common attention-management strategies: blocking out distractions, forcing yourself to focus, and trying to think positively. Jha argues that these attention-management strategies often fall short because they don\u2019t address the three root causes of scattered attention: evolution, stress, and multitasking.<\/strong> In this section, we\u2019ll walk through these root causes, examining why common strategies fail to produce lasting improvements.<\/p>\n\n\n\n

    Cause 1: Evolution<\/strong><\/h4>\n\n\n\n

    According to Jha, your attention system evolved to help you survive in environments filled with immediate threats (such as predators) and sudden opportunities (such as food sources or potential mates). For our ancestors, failing to notice these threats and opportunities could be fatal, so our attention systems evolved to automatically scan for changes in the environment and treat every unexpected stimulus as potentially significant. <\/strong>This instinct can make it difficult to sustain focus on a single task<\/a>. For example, while trying to write your novel, you may find you\u2019re continually distracted by background noises that don\u2019t signal a threat to your survival (like traffic sounds or barking dogs in your neighborhood).<\/p>\n\n\n\n

    Why Evolution Undermines Common Attention-Management Strategies<\/h5>\n\n\n\n

    Jha explains that people often try to subdue this evolutionary tendency for environmental vigilance by forcing themselves to focus. But she explains that it’s hard to override millions of years of evolutionary programming with sheer willpower<\/strong>. The vigilance system is deeply ingrained in the brain’s architecture and operates automatically unconsciously, which makes it resistant to conscious attempts to overpower it.<\/p>\n\n\n\n

    Another way people try to override this tendency is by blocking out environmental distractions. For example, while writing, you might turn off phone notifications and close your email. But Jha explains that blocking out distractions makes you even more aware of potential environmental changes. So, your attention still wavers\u2014you check the time, notice coworkers walking past, or wonder if you’ve missed any messages.<\/p>\n\n\n\n

    Cause 2: Stress<\/strong><\/h4>\n\n\n\n

    The second cause of scattered attention is stress. Jha explains that when you feel stressed, your brain activates primitive survival circuits that evolved to help you detect and escape dangers. These circuits narrow your attention scope, automatically shifting resources away from your current task and toward monitoring potential dangers<\/strong>. While this response helped our ancestors survive immediate physical threats, it disrupts the ability to maintain focus in modern environments where stress often comes from non-life-threatening sources like work deadlines or relationship challenges.<\/p>\n\n\n\n
