Lesson 20 · What is the relationship between psychology, movement and performance?
Why people start, and the much harder question of why they stay
The last inquiry question of this module, and it is the one that decides whether any of the others get used. A perfectly designed program produces nothing if nobody turns up to it; a well-taught skill is never acquired if the learner stops before the associative stage. This lesson is about the two things that decide that — whether a person sees themselves as someone who does this, and what they are actually doing it for. Both are more interesting than they sound. One of them explains why a promising athlete can be destroyed by a single injury, and the other explains how you can reward someone for doing something they love and make them want to do it less.
A group of children plays in a park every afternoon because they enjoy it. An adult starts paying them a small amount each time they play. After a few weeks the payments stop.
The children stop playing — and they play less than they did before any money was involved. Nothing else changed: same park, same game, same friends. Write down what you think happened to them.
Then a second scenario. A talented 17 year old has played representative sport since she was eight. Everyone she knows describes her as an athlete; it is the first thing said about her. She tears a knee ligament and is out for a year. Her coach is surprised by how badly she copes — far worse than a teammate with the same injury. What might explain the difference, and is it about the knee?
- Explain what personal identity is, and how it affects both participation and performance in sport.
- Explain what makes an exclusive athletic identity a risk as well as a strength.
- Explain how identity shapes who participates at all, including the effect of representation and of stereotypes.
- Distinguish intrinsic and extrinsic motivation, and positive and negative motivation, and combine the two axes.
- Explain the overjustification effect — how an extrinsic reward can reduce intrinsic motivation.
- Explain why negative motivation works and is still a poor foundation.
- Apply the three psychological needs — competence, autonomy and relatedness — to explain why people keep participating.
- Personal identity — a person's sense of who they are, made up of the roles, groups and attributes they see as defining them.
- Athletic identity — the degree to which a person defines themselves by their role as an athlete.
- Identity foreclosure — committing to one identity so exclusively that other possible selves are never developed.
- Motivation — the direction and intensity of effort: what a person chooses to do, and how hard they pursue it.
- Intrinsic motivation — motivation arising from the activity itself: enjoyment, interest, mastery.
- Extrinsic motivation — motivation arising from an outcome separate from the activity: a reward, a place in a team, praise.
- Positive motivation — the pursuit of a desirable outcome.
- Negative motivation — the avoidance of an undesirable one.
- Overjustification effect — the reduction in intrinsic motivation that can follow from rewarding an already-enjoyed activity.
- Self-efficacy — belief in one's capability at a specific task, met in Module 1 and in Lesson 16.
Personal identity is a person's sense of who they are — the roles, group memberships and attributes they treat as defining. It matters here because people act in ways consistent with who they believe they are, so identity predicts participation better than intention does. "I want to get fitter" is an intention and is famously unreliable. "I am someone who runs" is an identity, and it survives a cold morning that an intention does not.
Identity affects sport along three routes, and the syllabus's question — how it affects participation and performance — needs all three.
Whether you start at all. People join activities where they can imagine themselves belonging. If nobody in a setting looks like you, sounds like you, or shares your background, the signal is that it is not for you — and that signal is received long before anything is said. This is why representation in a sport is a participation issue rather than a public relations one, and it connects directly to the access and equity principles of Module 1 Lesson 4.
Whether you keep going when it is hard. Someone whose identity includes the activity interprets a bad session as something that happens to people like them. Someone who is merely trying it out interprets the same session as evidence they were right to doubt. Identical experience, opposite conclusions, because the interpretation runs through the identity.
How you perform under pressure. Identity shapes what a contest means. If the sport is where your sense of worth lives, every performance is a referendum on you, which raises the stakes of an ordinary game to a level that interferes with the skill — the Lesson 16 problem of an autonomous movement being disrupted by conscious attention, arriving here from a different direction.
The protective factor is not caring less. It is having other identities that are also real — student, friend, musician, sibling — so that a season lost is a serious loss rather than a total one.
Quick check: An athlete whose sense of self rests almost entirely on being an athlete is at greater risk after a serious injury mainly because:
Intrinsic motivation comes from the activity itself: enjoyment, interest, the satisfaction of getting better, the feeling of doing something well. Extrinsic motivation comes from something separate from the activity: a medal, selection, money, praise, a mark, avoiding a parent's disappointment.
Both work, and the difference that matters is durability. Extrinsic motivation is powerful and immediate, and it lasts exactly as long as the reward does. Intrinsic motivation is slower to build and far more robust, because the thing supplying it is the activity, which does not stop being available. Ask of any motivation: what happens to it when the person stops winning? That single question sorts the two.
This is not an argument against all rewards. A reward that carries information about competence — recognition for a genuine improvement, or an award for something specific and earned — generally supports intrinsic motivation, because it tells the person they are getting better, which is itself intrinsically satisfying. A reward that functions as control — paid per session, do this to get that — is the kind that displaces. The useful distinction for a coach is therefore not reward or no reward, but whether the reward informs or controls.
True or false: Adding a reward to an activity a person already enjoys will always increase their motivation to do it.
Positive motivation is the pursuit of something desirable: winning selection, improving a time, enjoying the game. Negative motivation is the avoidance of something undesirable: being dropped, letting the team down, being shouted at, gaining weight.
This axis is independent of the intrinsic-extrinsic one, and that is the point most often missed. Any motivation has one answer from each, which gives four combinations rather than two:
| Positive — pursuing something | Negative — avoiding something | |
|---|---|---|
| Intrinsic | Playing because it is enjoyable, and for the satisfaction of doing it well | Training to avoid the personal feeling of having let yourself down, or the frustration of playing badly |
| Extrinsic | Training to earn selection, a medal, or recognition from a coach | Training to avoid being dropped, criticised, or disappointing a parent |
Negative motivation works, which is why it persists, and it is a poor foundation, which is why it should not be a coach's main tool. Fear of being dropped does produce effort in the short term. Over time it has three costs: it is stressful, and chronic stress impairs both performance and health; it tends to produce cautious, error-avoiding play rather than the willingness to attempt difficult things that skill development requires; and it is not enjoyable, so it accelerates dropout in exactly the participants a coach most needs to retain.
The strongest combination is therefore positive and intrinsic — playing because the activity is worth doing and getting better is satisfying. The most fragile is negative and extrinsic, which lasts precisely as long as the threat is credible and leaves nothing behind when it is removed.
Match each reason for training to its classification on both axes.
- "I love the feeling when a move finally works"
- "I want to be selected for the representative side"
- "If I miss another session the coach will drop me"
- "I hate the feeling of knowing I could have done better"
- Intrinsic and positive
- Extrinsic and positive
- Extrinsic and negative
- Intrinsic and negative
Knowing that intrinsic motivation is better does not tell a coach how to produce it. The most useful account says that intrinsic motivation grows where three psychological needs are met, and it is worth knowing because each of the three maps onto something a coach or a club actually controls.
| Need | What it means | Supported by | Undermined by |
|---|---|---|---|
| Competence | The sense of being capable and improving | Achievable challenge, tasks matched to the learner's stage, feedback that shows progress, self-referenced comparison | Public norm-referenced comparison, tasks far beyond current ability, feedback that only identifies faults |
| Autonomy | The sense of having chosen this and having some control over it | Genuine choices, explaining reasons rather than issuing instructions, involving athletes in decisions | Being told everything, no input into the program, participating because a parent requires it |
| Relatedness | The sense of belonging and of mattering to others here | Being known by name, being picked, having a role, a group that would notice an absence | Being the one left out, a group organised only around the best players, anonymity |
The competence row is the participation problem of Lesson 12 restated in psychological terms, and the two together make the argument complete. A session pitched at the fittest player denies competence to everyone else, and the differentiation levers of Lesson 12 are how a coach supplies it. So differentiation is not a kindness; it is the mechanism by which a session produces motivation rather than consuming it.
Relatedness is the most under-rated of the three and the cheapest to supply. Whether someone would be missed is a stronger predictor of whether they come back than almost anything about the training itself — which is the finding Lesson 22 is built on.
Two truths and a lie. Which statement is false?
The dot point asks about the relationship between psychology, movement and performance, so the final step is to connect all of this back to what happens on the field.
| Route | Mechanism | Why it matters most |
|---|---|---|
| Through participation | Identity and met psychological needs decide whether a person trains at all, and for how many years | Nothing in this module reaches an athlete who has stopped playing. This is the largest effect by far, and the least discussed |
| Through practice quality | Intrinsically motivated athletes practise attentively and voluntarily, seek out difficulty, and tolerate the temporary decline that a technical change causes | Lesson 16 established that attentive practice, not elapsed time, moves a learner through the stages |
| Through the performance itself | What a contest means to a person changes what they attend to; an identity riding on the result raises the stakes to a level that can interfere with an automatic skill | This is the direct route, the one people think of first, and it is genuinely the smallest of the three |
Read the first row again, because it is the argument this whole inquiry question exists to make. Psychology's largest contribution to performance is not what happens in the final minute of a close game. It is that a person is still playing at 17 rather than having stopped at 13 — and everything else in this module then has someone to act on.
Fill the gaps. Type one word in each box.
Motivation arising from enjoyment of the activity itself is called motivation. Motivation that consists of avoiding an undesirable outcome is called motivation. Defining yourself so exclusively by one role that no other identities are developed is called identity .
Text description
- Two parts, one above the other.
- Above, a two by two grid crossing intrinsic and extrinsic motivation with positive and negative motivation, giving four cells each with an example: intrinsic positive playing for enjoyment, intrinsic negative training to avoid the feeling of having let yourself down, extrinsic positive training for selection, and extrinsic negative training to avoid being dropped, with the intrinsic positive cell marked as the most durable and the extrinsic negative cell marked as the most fragile, and a note asking what happens to each when the person stops winning.
- Below, the three psychological needs of competence, autonomy and relatedness shown as three cards, one per need, each giving the need in the athlete's words and listing what supports it (+) and what undermines it (−).
Activities · put the method to work
Choose an activity you currently do regularly and one you used to do and stopped. Be honest; this is more useful than it is comfortable, and nobody has to read it.
List every reason you do the current activity — aim for at least six, because the interesting ones are never in the first three. Then place each on the two-by-two grid from Card 06.
Stress-test each one. For each reason, write what would happen to it if you stopped improving for a year. The reasons that survive that are the ones actually holding you there.
Diagnose the activity you stopped. Using Card 07, identify which of competence, autonomy and relatedness was not being met. Most people find it was relatedness and had assumed at the time that it was lack of talent.
Name one change that would plausibly have kept you in it — specific enough that someone could have made it, not "it should have been more fun".
Then look at the two lists side by side. If your current activity's reasons are concentrated in the extrinsic-negative cell, that is worth knowing now rather than in two years — not because it is wrong, but because that cell is the one that empties first.
Odd one out. Three of these support the need for competence. Which one undermines it?
For each: identify what it is likely to do to identity, to motivation and to the three needs; say whether the effect is short-term or long-term; and propose an alternative that keeps what the decision was trying to achieve.
A club introduces a cash bonus for every goal scored in the under-14 competition.
A coach tells a squad before every match: "Anyone who doesn't work hard today won't be in the side next week."
A high-performance program requires 15 year olds to drop all other sports and commit exclusively to one.
A coach posts the weekly fitness test results, ranked, on the changing room wall.
Note that all four of these decisions work in the short term — that is precisely why they are common. Your answer is only useful if it says what each one buys as well as what it costs, and over what timescale.
Explain how motivation supports participation in sport, referring to intrinsic and extrinsic, and positive and negative motivation.
Explain requires how and why. The trap is treating intrinsic-extrinsic and positive-negative as one distinction with two labels each. They are independent axes, so the answer should cross them and produce four combinations, and saying so explicitly is worth a mark on its own.
Plan: define both axes; cross them with an example per cell; the durability argument and the sorting question; the overjustification effect; the costs of negative motivation; then the three needs as the practical answer.
Intrinsic motivation arises from the activity itself — enjoyment, interest, the satisfaction of improving — while extrinsic motivation arises from an outcome separate from the activity, such as selection, a medal or praise. Independently, positive motivation is the pursuit of a desirable outcome and negative motivation is the avoidance of an undesirable one, so any reason for participating has one answer from each axis. The critical difference is durability: extrinsic motivation is immediate and powerful but lasts only as long as the reward, whereas intrinsic motivation is slower to build and far more robust, because the source is the activity itself.
Two findings complicate the simple picture. First, rewarding an activity that was already intrinsically enjoyed can reduce motivation to do it — the overjustification effect — because the reward changes the person's account of why they are participating, so withdrawing it leaves them below where they started. Rewards that carry information about genuine competence generally support intrinsic motivation, while those that function as control displace it. Second, negative motivation does produce effort, which is why it persists, but it is stressful, encourages error-avoiding rather than adventurous play, and accelerates dropout.
Motivation determines both the direction and the intensity of effort, and it supports participation through two independent dimensions rather than one. Intrinsic motivation arises from the activity itself — enjoyment, interest and the satisfaction of improving — while extrinsic motivation arises from an outcome separate from the activity, such as selection, a medal, payment or praise. Independently of this, positive motivation consists of pursuing a desirable outcome and negative motivation of avoiding an undesirable one, so any given reason for participating has one answer on each axis, producing four combinations: playing because it is enjoyable is intrinsic and positive; training to avoid the personal feeling of having underperformed is intrinsic and negative; training to earn selection is extrinsic and positive; and training to avoid being dropped is extrinsic and negative. The property that matters most for participation is durability, and the question that sorts the four is what becomes of each when the person stops winning. Extrinsic motivation is immediate and powerful and lasts exactly as long as the reward remains available, whereas intrinsic motivation builds more slowly and is far more robust, because its source is the activity, which does not stop being available when results decline. Two findings complicate any simple prescription to use rewards. The first is the overjustification effect: introducing an extrinsic reward for an activity that was already intrinsically enjoyed can reduce the motivation to do it, because the reward alters the person's own account of why they are participating, so that when the reward is withdrawn participation falls below its original level. The distinction that matters is not whether to reward but whether a reward informs or controls — recognition of a genuine, specific improvement supplies information about competence and supports intrinsic motivation, while payment per session functions as control and displaces it. The second is that negative motivation genuinely works in the short term, which is why it remains common, but carries three costs over a season: it is stressful, and chronic stress impairs both performance and health; it produces cautious, error-avoiding play rather than the willingness to attempt difficult things that skill development requires; and it is not enjoyable, so it accelerates dropout among precisely the participants a club most needs to retain. The practical account of how intrinsic motivation is produced is that it grows where three psychological needs are met: competence, the sense of being capable and improving, supported by achievable challenge and by comparison with the participant's own past results rather than with others; autonomy, the sense of having chosen the activity and having some say in it, supported by genuine choices and by explaining reasons rather than issuing instructions; and relatedness, the sense of belonging and of being missed if absent, which is the cheapest of the three to supply and among the strongest predictors of return. Motivation therefore supports participation principally by determining whether a person is still taking part at all several years later, which matters more than any single performance, since no training program, skill model or nutritional strategy reaches an athlete who has stopped playing.
Analyse how personal identity affects an individual's participation and performance in sport, and explain why a strong athletic identity can be both an advantage and a risk.
Analyse means draw out relationships and implications. The second half asks for an advantage and a risk from the same property, so the answer must show how one mechanism produces both — not list benefits then list drawbacks as if they were unrelated.
Plan: define identity and state why it predicts behaviour better than intention; three routes — starting, persisting, performing; then the advantage of strong athletic identity; then the same property producing the risk, via foreclosure; then the protective factor and what it is not.
Personal identity is a person's sense of who they are, composed of the roles, groups and attributes they treat as defining, and people act in ways consistent with who they believe themselves to be. This is why identity predicts participation more reliably than intention: "I want to get fitter" is an intention and is famously unreliable, while "I am someone who runs" is an identity and survives a cold morning that an intention does not.
Identity affects sport along three routes. It affects whether a person starts, because people join settings in which they can imagine belonging, so representation determines who takes up a sport before anything is said to anyone. It affects whether they persist, because identity governs interpretation: an athlete whose identity includes the activity reads a poor session as something that happens to people like them, while a newcomer reads the identical session as confirmation that they do not belong. And it affects performance, because what a contest means to a person changes what they attend to.
Personal identity is a person's sense of who they are, composed of the roles, group memberships and attributes they treat as defining, and it bears on sport because people act in ways consistent with who they believe themselves to be. This makes identity a better predictor of participation than intention: "I want to get fitter" is an intention and is unreliable, whereas "I am someone who runs" is an identity and survives a cold morning that an intention does not. Identity affects participation and performance along three routes. First, it affects whether a person begins at all, because people join settings in which they can imagine themselves belonging; where nobody in a sport shares a person's background, appearance or circumstances, the signal that it is not for them is received long before anything is said, which is why representation in a sport is a participation issue rather than a presentational one. Second, it affects whether they persist, because identity governs how experience is interpreted. An athlete whose identity already includes the activity reads a poor session as a normal event in the life of someone like them; a newcomer reads the identical session as confirmation of the doubt they arrived with. The experience is the same and the conclusions are opposite, and since persistence through poor sessions is what moves a learner through the stages of skill acquisition, this route has a large cumulative effect on eventual performance. Third, it affects the performance itself, because what a contest means to a person changes what they attend to during it; if a person's sense of worth rests on the outcome, an ordinary game becomes a referendum on them, raising the stakes to a level that can disrupt an otherwise automatic skill. A strong athletic identity is therefore a genuine advantage. It sustains the very large volume of deliberate practice that high performance requires, it makes hard training feel like an expression of who the person is rather than an imposition, it supports persistence through injury and poor form, and it provides a ready-made social group that reinforces the same behaviours. The risk arises from exactly the same property. When being an athlete is not one important identity among several but effectively the only one, the person is in a state of identity foreclosure: alternative possible selves have never been developed, because all available time and attention went to the one. The consequence appears when sport is removed, which it eventually is for everyone — by injury, by deselection, or by retirement. The person has lost not merely an activity but the answer to who they are, with nothing developed to take its place, which is why a serious injury can be far more damaging to one athlete than to a teammate with the identical physical injury, and why retirement from elite sport is so frequently difficult. Even before that point, an exclusive identity intensifies the third route above, since every performance carries the weight of the whole self. The protective factor is worth stating precisely, because it is easily misread: it is not caring less about the sport, which would forfeit the advantage, but holding other identities that are also genuinely real — student, friend, sibling, musician — so that the loss of a season is a serious loss rather than a total one. Identity, then, is not merely a background variable in sport; it determines who arrives, who stays, and what a result is taken to mean.

Activity 1 guidance: The instruction to list at least six reasons in step 1 matters because the first three are almost always the socially acceptable ones — enjoyment, fitness, friends — and the reasons that actually explain attendance turn up at four, five and six. Step 2 is the part that does the work: a reason that would not survive a year without improvement is a reason that is currently being carried by something else, and students are frequently surprised to find that most of their stated reasons fail this test while one unstated one passes it. Step 3 has a strong and consistent pattern worth anticipating: when students diagnose an activity they stopped, relatedness is the most commonly identified unmet need, and the great majority report that at the time they attributed stopping to a lack of ability. That gap between the real cause and the attributed cause is the single most valuable thing this activity produces, and it is also a direct instance of the Lesson 16 finding that a skill-acquisition or belonging problem is routinely misdiagnosed as a personal deficiency. Step 4's requirement for specificity should be enforced: "it should have been more welcoming" is not a change anyone could have made, whereas "someone should have learned my name in the first three weeks" is.
Activity 2 guidance: All four decisions are effective in the short term and that must be conceded, or the analysis is just disapproval. Decision 1 buys immediate attacking intent and risks the overjustification effect on a group who were mostly playing for enjoyment; it also damages relatedness by rewarding only the players in scoring positions. A better alternative retains recognition while making it informational and team-wide — recognising a specific improvement or a decisive contribution rather than paying per goal. Decision 2 buys visible effort in that session and costs willingness to attempt difficult things, since a player fearing deselection selects the safe option every time, which directly undermines skill development; the alternative states what the coach actually wants in positive terms and specifies it behaviourally. Decision 3 buys practice volume in one sport and risks identity foreclosure at exactly the age when other identities should be forming, as well as the injury and dropout costs of early specialisation noted in Lesson 19; the alternative protects one non-sport commitment rather than abolishing the program. Decision 4 buys a visible motivational spike among the top few and costs competence for everyone below the median, week after week; the alternative reports each athlete their own change over time privately, which is the Lesson 15 point about self-referenced rather than norm-referenced comparison. Most students identify decision 4 as the most damaging, and the strongest justification is that its harm is weekly and cumulative and falls hardest on the participants most at risk of leaving.
SA 1 (4 marks): Intrinsic defined as arising from the activity itself, with an example such as playing for enjoyment or the satisfaction of improving [1]. Extrinsic defined as arising from an outcome separate from the activity, with an example such as selection, a medal or praise [1]. Positive defined as pursuing a desirable outcome, with an example [1]. Negative defined as avoiding an undesirable outcome, with an example [1]. A strong answer also notes that the two axes are independent, so any reason has one answer from each; an answer that treats positive and negative as synonyms for intrinsic and extrinsic loses at least two marks, because the examples will not distinguish them.
SA 2 (5 marks): Defines negative extrinsic motivation and gives an example such as training to avoid being dropped [1]. Explains why it works immediately — the threat is credible and the consequence is imminent, so it reliably produces effort in the short term [1]. Cost one: it is stressful, and chronic stress impairs both performance and health [1]. Cost two: it produces cautious, error-avoiding play, since attempting a difficult skill risks the very outcome being avoided, which directly retards skill development [1]. Cost three: it is not enjoyable, so it accelerates dropout, and typically among the participants who would most benefit from continuing [1]. A strong answer closes by naming what to build instead — competence through achievable challenge and self-referenced progress, autonomy through genuine choice, and relatedness through belonging. An answer that merely asserts negative motivation is bad, without conceding that it works, cannot reach the top band.
SA 3 (6 marks): Defines personal identity and explains why it predicts behaviour better than intention [1]. Route one, starting: people join settings where they can imagine belonging, so representation affects who takes up a sport [1]. Route two, persisting: identity governs how a poor session is interpreted, so identical experience produces opposite conclusions in an insider and a newcomer [1]. Route three, performing: what the contest means changes what the athlete attends to, and an identity riding on the result can disrupt an automatic skill [1]. The advantage of a strong athletic identity: it sustains the practice volume high performance requires, supports persistence through setbacks, and supplies a reinforcing social group [1]. The risk from the same property: identity foreclosure, in which no alternative identities are developed, so injury, deselection or retirement removes not only the activity but the answer to who the person is — with the protective factor being other genuinely held identities rather than caring less [1]. An answer that lists advantages and then unrelated disadvantages, rather than showing one property producing both, caps at 4.
Identity predicts behaviour better than intention does. "I want to get fitter" loses to a cold morning; "I am someone who runs" does not. Identity works along three routes: whether you start, because people join where they can imagine belonging — which makes representation a participation issue; whether you persist, because identity decides how a bad session is interpreted, so the same experience confirms an insider and dismisses a newcomer; and how you perform, because what a contest means changes what you attend to.
A strong athletic identity is an advantage and a risk from the same property. It sustains the practice volume that high performance needs. And when it is exclusive — identity foreclosure — injury, deselection or retirement removes not a season but the answer to who you are. The protective factor is not caring less; it is having other identities that are genuinely real.
Two axes, not two names. Intrinsic and extrinsic asks where the motivation comes from; positive and negative asks whether you are pursuing or avoiding. Every reason has one answer from each, which gives four cells. The sorting question is: what happens to this when the person stops winning? Intrinsic and positive survives it. Extrinsic and negative does not.
Rewards can backfire, and the distinction is inform versus control. The children in the park stopped because the payment rewrote why they were playing, and removing it left nothing — the overjustification effect. But a reward that tells someone they have genuinely improved supports intrinsic motivation, because competence is itself satisfying. Likewise negative motivation genuinely works, and still costs you stress, cautious error-avoiding play, and the players who quietly stop coming.
Competence, autonomy, relatedness. That is the practical answer to "how do I produce intrinsic motivation", and each maps onto something a coach controls. Note that the competence row is Lesson 12's differentiation argument in psychological language — differentiating a session is not kindness, it is the mechanism. And the biggest thing psychology does for performance is not the last minute of a close game; it is that the person is still playing at 17 instead of having stopped at 13.
Lesson 21 takes the third sub-question: self-regulation, and how exercise behaviour is actually changed and sustained — which is the part that decides whether any of this survives contact with an ordinary week.
