A 2023 study published in PLOS ONE examined motor imagery ability in college baseball players with throwing yips, and what the researchers found challenges nearly every conventional approach to mental training that coaches and sport psychologists have been using for decades. The study compared three groups of athletes, those currently experiencing yips, those who had recovered from yips, and healthy controls who had never experienced the condition. Researchers Aoyama and colleagues assessed both general motor imagery ability, like imagining yourself running or jumping, and task-specific imagery related to throwing. What emerged wasn't a story about athletes who couldn't visualize success or who lacked imagination. It was a story about athletes whose minds were generating vivid, intrusive images of failure that persisted even after their symptoms resolved.

Athletes with yips showed significantly higher vividness of negative throwing-specific imagery compared to both control and recovered groups. When asked to imagine a wild throw, an errant toss that sailed past the target, these athletes could conjure that image with crystal clarity. But here's what makes this finding particularly important, there was no significant difference in positive imagery vividness across any of the groups. Athletes with yips could imagine successful throws just as vividly as healthy athletes. The problem wasn't that they couldn't see success, it's that they could see failure too clearly, and that negative imagery was overwhelming the positive. In healthy athletes, positive and negative imagery were inversely correlated, when one went up, the other went down. That protective relationship was absent in both the yips and recovered groups, suggesting that once the pattern of vivid negative imagery establishes itself, it doesn't simply disappear when symptoms improve.

What the Study Found

The researchers recruited college baseball players across three groups, 10 athletes currently experiencing throwing yips, 10 who had previously experienced yips but were now symptom-free, and 20 healthy controls. All participants completed the Movement Imagery Questionnaire-Revised, which assesses general motor imagery ability across different sensory modalities, and a task-specific throwing imagery questionnaire designed to measure both positive and negative imagery vividness related to baseball throwing.

General motor imagery ability, the capacity to imagine oneself performing non-throwing movements like running, jumping, or reaching, was not impaired in athletes with yips. This is important because it tells us the issue isn't a global deficit in imagination or visualization capacity. These athletes could mentally simulate movement just fine when the movement wasn't the one tied to their performance anxiety. The deficit was specific to the task that had become psychologically loaded.

When it came to throwing-specific imagery, athletes with yips showed significantly higher vividness of negative imagery compared to both controls and recovered athletes. They could vividly imagine throwing errors, wild pitches, balls sailing over the catcher's head, throws that felt uncontrolled or chaotic. This wasn't just a mild preference or a fleeting thought, it was a robust difference in how clearly and consistently these negative scenarios played out in their minds. Critically, there was no difference in positive imagery vividness between groups. All athletes, regardless of whether they had yips or not, could imagine successful throws with similar clarity. The yips weren't caused by an inability to visualize success, they were associated with an enhanced ability to visualize failure.

The relationship between positive and negative imagery differed across groups. In healthy athletes, positive and negative imagery were inversely correlated, meaning that athletes who had strong positive imagery tended to have weaker negative imagery, and vice versa. This makes intuitive sense, if your mind is occupied with images of success, there's less room for images of failure. But in athletes with yips and in recovered athletes, this inverse relationship disappeared. Both types of imagery could coexist at high levels, which suggests that the mental architecture that normally keeps negative imagery in check had been disrupted. Even more striking, recovered athletes, those who were no longer experiencing throwing problems, still demonstrated elevated negative imagery compared to controls. They had resolved the motor symptoms, but the cognitive pattern persisted.

The researchers proposed that psychological factors like anxiety generate or reinforce negative motor imagery, creating a feedback loop where the imagery perpetuates impaired performance, which increases anxiety, which strengthens the imagery. This isn't just speculation, it aligns with a broader body of research showing that anxiety narrows attention, increases threat monitoring, and makes negative outcomes more salient. When you're anxious about throwing, your brain becomes hypervigilant for signs of failure, and that hypervigilance manifests as vivid mental simulations of exactly what you're trying to avoid.

Why This Information Is Important

To be honest, this reminds me of every conversation I've had with coaches who tell anxious athletes to "just think positive" or "visualize success" as if the problem is that the athlete hasn't thought of trying that yet. Of course they've tried it. Every athlete with performance anxiety has spent hours trying to replace negative thoughts with positive ones, trying to imagine themselves executing perfectly, trying to convince themselves it's going to be fine this time. And it doesn't work, not because positive imagery is useless, but because you can't just layer positive imagery on top of unresolved negative scripts and expect the negative scripts to disappear. The research makes this painfully clear. Athletes with yips can visualize success just as well as anyone else, but that ability doesn't protect them because the negative imagery is still there, still vivid, still intrusive, and still dominating their attentional space when it matters most.

The persistence of elevated negative imagery even in recovered athletes is particularly telling. These are individuals who have regained their ability to throw without symptoms, who by any external measure have overcome the yips, yet their minds are still generating vivid images of failure. This suggests that recovery from yips, at least as it's currently conceptualized and treated, often involves finding ways to perform despite the negative imagery rather than actually eliminating it. The athlete learns to cope, to manage the anxiety, to execute the skill even while their brain is showing them a highlight reel of everything that could go wrong. That's not a bad outcome, coping is valuable, but it raises questions about whether we're addressing the root cause or just teaching athletes to white-knuckle their way through it.

Research on ironic process theory provides a compelling explanation for why negative imagery is so powerful and why trying to suppress it often backfires. A study examining baseball pitchers under high-pressure conditions found that performance breakdowns follow two distinct neurological paths depending on what instructions the athlete receives. One group was told to hit a specific target, the other group was told to avoid a specific zone, don't throw it here. Under pressure, both groups showed decreased accuracy, but the mechanisms were completely different. The target-only group showed mechanical breakdown, increased variability in elbow flexion, lead foot placement, and body positioning. This is reinvestment theory in action, the athlete starts consciously monitoring and controlling movements that should be automatic, which disrupts the fluidity of expert performance.

But the ironic group, the athletes told not to throw to a specific zone, showed no significant change in any kinematic variables. Their mechanics stayed perfect under pressure. Yet they hit the forbidden zone significantly more often than they did in low-pressure trials. They maintained expert execution but targeted the exact location they were trying to avoid. The brain, when told "don't think about X," immediately thinks about X in order to monitor whether it's successfully not thinking about X, and that monitoring makes X more salient and more likely to become the dominant response under stress. If you tell a pitcher "don't miss high," their brain starts simulating what missing high looks like, how it feels, where the ball goes, and under pressure, that simulation becomes a blueprint for action.

This is exactly what's happening in athletes with yips. They're not just experiencing general anxiety, they're experiencing anxiety that's been conditioned to a specific movement pattern, and that conditioning manifests as vivid negative imagery. Every time they throw and it goes wrong, the negative imagery gets reinforced. Every time they anticipate throwing and worry about it going wrong, the imagery gets rehearsed. The mind is doing what minds do, preparing for threats, simulating outcomes, trying to predict and prevent disaster. But in doing so, it's creating the very outcome it's trying to avoid.

Research on heart rate variability biofeedback in baseball players demonstrates that anxiety regulation techniques can actually break this cycle. A study of college hitters found that 10 days of HRV biofeedback training significantly reduced cognitive anxiety and improved batting performance. Batting scores increased from 9.8 to 19.8, infield hit ratio improved, and quality of contact went up. The intervention wasn't about teaching better swing mechanics or providing more positive imagery, it was about giving athletes a tool to regulate their autonomic nervous system, to shift from a state of sympathetic dominance, fight or flight, to a more balanced state where parasympathetic activity could support focus and execution. When anxiety decreases, negative imagery loses some of its vividness and intrusive quality, which creates space for more adaptive mental processes.

The role of cognitive load in exposing movement inefficiencies also becomes relevant here. Research using a single-leg step-down test with a concurrent cognitive task found that pitchers who showed increased transverse plane motion of the trunk or pelvis during the dual-task condition were significantly more likely to be in the high elbow torque, low velocity group. The cognitive load didn't create new movement problems, it revealed existing control issues that weren't visible when the athlete's full attention was available to compensate. This is what happens during competition. The athlete is managing not just the physical task but also strategic decisions, awareness of game situation, crowd noise, internal dialogue, and in the case of athletes with yips, intrusive negative imagery. All of that cognitive load taxes attentional resources, and when attention is divided, the compensatory mechanisms that allow the athlete to perform despite underlying issues start to fail.

Research on resting heart rate variability in professional pitchers shows that autonomic recovery takes time and varies considerably between individuals. Day two after a start showed suppressed HRV, indicating elevated sympathetic tone and reduced parasympathetic recovery, with most pitchers returning to baseline by day three. But baseline HRV varied enormously across athletes, which means that what constitutes "recovered" for one pitcher might be significantly different for another. This variability matters when we're talking about anxiety-related performance issues because athletes with chronically lower HRV or slower recovery may be more vulnerable to developing and maintaining negative imagery patterns. They're operating with less autonomic flexibility, which makes it harder to downregulate anxiety and harder to shift out of threat-focused attentional states.

Even research on acute sympathetic activation, like the study showing that nicotine increased sympathetic drive and improved hitting performance, underscores the complexity of arousal and performance. The athletes who received nicotine showed increased heart rate, altered HRV indicating sympathetic dominance, and improved motor reaction time and hit percentage. This tells us that arousal state matters, but it's not as simple as "high arousal equals bad performance." The key is whether the arousal is controllable and whether the athlete can channel it into focus and execution rather than letting it spiral into anxiety and performance disruption. Athletes with yips aren't failing because they're too aroused, they're failing because their arousal is paired with negative imagery and avoidant focus, which directs attention toward the outcome they're trying to prevent.

How Can This Information Be Applied

If you're a coach or practitioner working with athletes who have performance anxiety or task-specific motor disruptions like the yips, the first and most important takeaway is that positive imagery alone is not a sufficient intervention. You cannot simply tell an athlete to visualize success and expect that to override vivid, intrusive negative imagery. The research is clear on this, athletes with yips can visualize success just as well as anyone else, but that ability doesn't protect them because the negative imagery is still present and still dominant under stress. Your intervention needs to directly address the negative imagery, not just try to bury it under more positive thoughts.

Guided rescripting is one approach that shows promise. This involves having the athlete deliberately imagine the negative scenario, the wild throw, the loss of control, but then actively rewrite the script in real time. Instead of letting the negative image play out to its feared conclusion, the athlete intervenes, maybe they imagine regaining control mid-throw, or they imagine the throw going wild but then immediately following it with a perfect throw, or they imagine handling the negative outcome calmly without catastrophizing. The goal is to reduce the emotional charge of the negative imagery and to give the athlete a sense of agency over what happens next. You're not trying to eliminate the negative imagery entirely, you're trying to change its meaning and reduce its power.

Contrast-based imagery training is another option. This involves systematically pairing positive and negative imagery in the same session, having the athlete imagine a successful throw, then a failed throw, then a successful one again, deliberately creating the juxtaposition. Over time, this can help restore the inverse relationship between positive and negative imagery that's disrupted in athletes with yips. The brain starts to learn that negative imagery doesn't have to dominate, that it's possible to shift between the two, and that the presence of a negative image doesn't inevitably lead to a negative outcome.

Anxiety regulation has to be a central component of any intervention. The HRV biofeedback research shows that teaching athletes to control their autonomic state can produce measurable improvements in performance, not by fixing mechanics or improving physical capacity, but by reducing the cognitive and physiological load that anxiety creates. HRV biofeedback isn't the only tool here, progressive muscle relaxation, diaphragmatic breathing, mindfulness-based approaches, all of these can help athletes shift from sympathetic dominance to a more balanced autonomic state. The key is giving athletes a concrete skill they can use to regulate their nervous system, not just telling them to relax or calm down.

The ironic process research suggests that instructional language matters enormously. If you're coaching an athlete who struggles with accuracy, telling them "don't miss high" or "don't bounce it" is actively harmful. Those avoidant instructions create the exact imagery and attentional focus that lead to the error you're trying to prevent. Instead, use approach-oriented language that directs attention toward what you want, "hit the catcher's chest," "keep it on a line," "drive through the target." This isn't just semantics, it's changing what the athlete's brain is simulating and what their attention is monitoring. When you give an avoidant instruction, the athlete has to first imagine the error in order to avoid it, and under pressure, that error image becomes the dominant motor plan.

Work on reducing cognitive load during skill execution. The dual-task research shows that cognitive demand exposes movement control issues that aren't visible when the athlete has full attentional resources. If an athlete is dealing with intrusive negative imagery, that's cognitive load. If they're monitoring their mechanics consciously, that's cognitive load. If they're worrying about consequences, that's cognitive load. The more of these demands you can reduce, the more attentional capacity the athlete has available for the actual task. This might involve simplifying pre-throw routines, creating clear focus cues that narrow attention to one or two key elements, or using distraction techniques that occupy the conscious mind with something neutral so the motor system can execute automatically.

Understand that recovery from yips, as evidenced by the persistence of negative imagery in recovered athletes, doesn't necessarily mean the cognitive pattern is gone. It might mean the athlete has learned to perform despite it. That's valuable, but it also means there's residual vulnerability. An athlete who has recovered from yips is at higher risk for relapse if they encounter a high-stress situation or a performance failure that reactivates the negative imagery. Build in maintenance strategies, periodic check-ins on mental state, continued use of anxiety regulation techniques, ongoing attention to instructional language, to reduce the likelihood of recurrence.

Recognize individual differences in autonomic flexibility and recovery. The HRV research shows enormous variability between athletes in baseline nervous system function and how quickly they recover from stress. Athletes with chronically lower HRV or slower recovery curves may need more proactive anxiety management, more emphasis on recovery between high-stress events, and possibly earlier intervention when signs of performance anxiety start to emerge. Monitoring HRV can give you objective data about an athlete's autonomic state, which can inform when to push and when to back off.

Finally, don't treat this as purely a mental issue that can be solved with mental techniques alone. The yips involve motor execution, attentional control, autonomic regulation, and conditioned fear responses. Effective intervention requires a multi-pronged approach that addresses all of these components simultaneously. Anxiety regulation techniques to calm the nervous system, guided imagery work to address the negative scripts, changes in instructional language to avoid creating avoidant focus, mechanical work to rebuild confidence in the physical skill, and deliberate exposure to progressively challenging situations to recondition the fear response. One piece alone is unlikely to be sufficient.

Conclusion

The finding that athletes with throwing yips show significantly elevated vividness of negative throwing-specific imagery, while maintaining normal positive imagery ability, fundamentally challenges conventional mental training approaches that emphasize visualization of success. The problem isn't that these athletes can't imagine success, it's that their minds are generating vivid, intrusive images of failure that persist even after motor symptoms resolve. Simply adding more positive imagery on top of these negative scripts is insufficient because the two can coexist, and under pressure, the negative imagery dominates.

Research on ironic process theory demonstrates the mechanism behind this phenomenon. When athletes are given avoidant instructions, "don't throw it here," their brains simulate the forbidden outcome in order to monitor whether they're successfully avoiding it, and under stress, that simulation becomes the motor plan. The athlete maintains perfect mechanics but executes the exact error they were trying to prevent. This is why negative imagery is so powerful and why trying to suppress it or override it with positive thoughts often fails. The act of trying not to think about something makes you think about it more, and in the context of motor performance, thinking about an error increases the likelihood of committing that error.

The persistence of elevated negative imagery in recovered athletes suggests that overcoming the yips often involves learning to perform despite the imagery rather than eliminating it entirely. This residual pattern creates vulnerability for relapse if the athlete encounters high-stress situations or performance failures that reactivate the negative scripts. Effective intervention requires directly addressing the negative imagery through techniques like guided rescripting and contrast-based training, regulating anxiety through HRV biofeedback or other autonomic regulation strategies, using approach-oriented rather than avoidant instructional language, and managing cognitive load during execution.

The complexity of the yips, the interplay between motor execution, attention, anxiety, and conditioned fear responses, means that no single intervention is likely to be sufficient. Athletes need a comprehensive approach that targets multiple components simultaneously, calming the nervous system, rewriting the negative scripts, directing attention appropriately, and rebuilding confidence through successful execution. The research provides a roadmap for how to do this, but it also underscores the need for patience and persistence. Patterns of vivid negative imagery don't develop overnight, and they don't disappear overnight. Recovery is a process, and in many cases, it's a process of learning to perform effectively even when the negative imagery hasn't completely resolved.
