About the Lab

Bridging motor learning research and coaching practice

A gap exists between evidence-based pedagogical practices aimed at enhancing motor learning and performance, and what takes place on the field in coaching and physical education.

Coach education has focused primarily on the technical, sport-specific side of coaching — what to coach. Out of 285 coach development programmes reviewed by Lefebvre and colleagues, three addressed pedagogy. The result is that coaches are certified largely on what they know about their sport, and left to work out how to teach it.

That matters because time spent listening is time away from the perception-action workspace. Coordination does not emerge from listening.

The Skill Acquisition Lab exists to close that gap: to make what the motor learning literature actually supports — including where it is contested — usable by the people running practice.

Kyle Forbes Bissell, M.Ed.

Faculty and Director of Pedagogical Support, Exercise & Sport Studies, Smith College · PhD candidate, Rocky Mountain University of Health Professions · Formerly Education Manager, USA Archery

I teach motor learning and coach education at Smith College, where I support the faculty and instructors who deliver our performance courses and our S.M. in Sport Coaching. Before that I led coach education at USA Archery, building development pathways around a competency matrix, an athlete development model, and a quality coaching framework.

My doctoral research develops the SASS-SC, a scale for measuring how frequently coaches apply evidence-based motor learning strategies. What I teach and what I research are the same problem approached from two directions.

SAM-SAS

The Sport Agnostic Map of Skill Acquisition Strategies

How the strategies available to a coach relate to one another — and where the hierarchy stops being able to explain them.

This is a proposed organisation of the field, not a settled one. As far as I know it is the first attempt to organise motor learning strategies this way for sport coaching, and parts of it will be wrong. It is offered so that coaches have somewhere to start and so that colleagues have something specific to argue with.
FRAMEWORK DOMAIN SUBDOMAIN SUBDOMAIN of micro-pedagogy Motor Learning strategies · SAM-SAS Pedagogy structural · not scored Micro-Pedagogy structural · not scored Macro-Pedagogy explicit implicit Practice Design a domain, and scored · 10 items Attentional Focus scored · 10 items Challenge Level scored · 10 items Intrinsic Motivation scored · 10 items
Solid lines: the structureWhat contains what. Only five nodes are scored; two exist to hold the others.
Faint curves: a shared leverOne thing a coach adjusts that lands in two subdomains at once. The structure cannot show these; they cut across it.
Teal curve: a theoretical couplingTwo subdomains bound by a theory that predicts they combine, not merely co-occur.

A second axis runs through all of it. Stage of motor learning is not a node either. Whichever strategy a coach reaches for, the choice is keyed to where the athlete is: “Regardless of the theoretical preferences of a coach, coaches can adapt instructional strategies, such as constraints, to optimize the level of challenge for a participant’s stage of motor learning.”

The instrument

SASS-SC

Skill Acquisition Strategies Scale for Sport Coaches.

What it is

The SASS-SC is a 50-item self-report scale measuring how frequently sport coaches use evidence-based motor learning strategies. Coaches rate each item against the past two weeks on a seven-point frequency scale, from never to every time. Five subdomains, ten items each, no reverse-scored items.

What it is not

The SASS-SC is not intended to provide a measure of coach quality. Receiving a higher score on certain items would not necessarily indicate better coaching quality compared to a coach who scored lower on certain items.

Asking coaches to recall whether they implemented a particular motor learning strategy measures their perception of what took place — not how that strategy was received by the learner, or what came of it. A higher score does not mean more learning happened.

Where the validation stands

The scale is under development. Content validity work is complete; factor analysis and reliability testing are underway. It has not yet been validated, and no claim on this site should be read as saying otherwise. Anything published here about its performance will be published with its limitations attached.

As a reflection tool

Rate yourself after a session or at the end of a week, and look at the pattern rather than the score. Which strategies do you reach for by default, and which have you simply never tried?

As a pre-flight checklist

Read the items before you design a session, as an evidence-informed menu of strategies you might consider on any given day.

As a shared vocabulary

Coach developers and departments can use the items to talk about how coaching happens, not just what gets coached.

Attentional Focus

Theory

Wulf, G., & Lewthwaite, R. (2016). Optimizing performance through intrinsic motivation and attention for learning: The OPTIMAL theory of motor learning. Psychonomic Bulletin & Review, 23(5), 1382-1414. https://doi.org/10.3758/s13423-015-0999-9

The paper this subdomain rests on. OPTIMAL argues attention and motivation are not separate levers but combine — external focus, autonomy support and enhanced expectancies work better together than any of them alone.

Where the constrained action hypothesis comes from: consciously attending to your own body constrains the motor system and undermines automaticity. The mechanism behind almost every external-cue recommendation you will hear.

Meta-analysis

Chua, L. K., Jimenez-Diaz, J., Lewthwaite, R., Kim, T., & Wulf, G. (2021). Superiority of external attentional focus for motor performance and learning: Systematic reviews and meta-analyses. Psychological Bulletin, 147(6), 618-645. https://doi.org/10.1037/bul0000335

The largest synthesis of external versus internal focus. External wins on performance, retention and transfer, and age, health and skill level did not moderate the effect — a stronger claim than most in this field.

Systematic review & meta-analysis

Nicklas, A., Rein, R., Noël, B., & Klatt, S. (2024). A meta-analysis on immediate effects of attentional focus on motor tasks performance. International Review of Sport and Exercise Psychology, 17(2), 668-703. https://doi.org/10.1080/1750984x.2022.2062678

Confirms external over internal, and distal cues over proximal, but reports confidence intervals wide enough that the authors decline to generalise across all tasks and skill levels. Read alongside Chua for the honest range.

Review

A narrative review of 54 studies, 46 of them favouring external focus. Useful for seeing how consistent the pattern looked before the more cautious recent syntheses.

Systematic review & meta-analysis

Carnero-Diaz, A., Pecci, J., Calvo Lluch, Á., & Camacho-Lazarraga, P. (2025). Use your imagination for better performance. Effects of analogy instruction in motor skills. A systematic review and meta-analysis. Psychology of Sport and Exercise, Article 102766. https://doi.org/10.1016/j.psychsport.2024.102766

Analogies outperformed explicit instruction for novices and youth — but explicit instruction held up better under stress. The authors argue analogy is underused in coaching and physical education.

Conflicting evidence · boundary condition

The clearest exception to the rule. For building muscle in resistance training, internal cues outperformed external ones. If you coach strength, this is the study that stops you over-applying external focus.

Cues built without the athlete’s needs and preferences in mind are less effective. A reminder that a cue is a communication, not an incantation.

Seventy-five studies, 2,228 participants, and no clear support for the guidance hypothesis or for reduced feedback frequency improving learning. The authors describe much of the literature as severely underpowered.

High risk of bias in 18 of 24 studies, and conflicting evidence on feedback frequency, timing and duration. Worth reading before committing to any particular feedback schedule.

Motor imagery produces a real effect on performance, strongest when combined with physical practice. The authors note how little of this work has been done in coaching or physical education settings.

Whole versus part practice. The decision turns on task complexity and organisation, not on a general preference for either.

The whole-versus-part advantage reverses with age: fifth graders learned juggling better whole, first and third graders better in parts. The clearest evidence that breaking a skill down is a judgement, not a rule.

Field hockey across five practice schedules: no difference in skill acquisition or retention.

Attentional Focus

  • 1I use cues focused on the equipment or its motion through space to direct the athlete's attention away from their body
  • 2I use analogies to focus athletes' attention on the intended movement outcome
  • 3I have athletes mentally rehearse their movement to reinforce their intended focus before their next physical attempt
  • 4I give feedback on how a skill was executed to focus attention on their technique
  • 5I use demonstrations with verbal cues to focus attention on key skill characteristics
  • 6I use questioning (e.g., "How did that feel?") to encourage athletes to tune into their own internal feedback
  • 7I have athletes judge the accuracy of their attempt before providing feedback to improve their ability to detect errors
  • 8I reduce the frequency of my verbal feedback over time to help athletes become less dependent on my coaching
  • 9I only provide feedback when errors fall outside a defined acceptable range, encouraging athletes to self-correct
  • 10I use cues that target the senses (e.g., sound, rhythm) to help athletes find consistent focus

Challenge Level

  • 11I adjust task difficulty to ensure a success rate (e.g., at least 70%) that promotes learning
  • 12I modify task difficulty based on athlete skill level to invite skill development
  • 13I change the environment (e.g., lighting, noise, terrain) to increase challenge of the task
  • 14I simplify the requirements of the whole movement to reduce cognitive load for the athlete
  • 15I isolate specific components of a skill to reduce technical difficulty for the athlete
  • 16I modify practice activities to maintain an appropriate challenge level for the athlete's skill level
  • 17I adjust activities based on an ongoing assessment to account for individual differences (e.g., fatigue, strength)
  • 18I simplify tasks following repeated failures to ensure athletes experience enough success to stay engaged in learning
  • 19I increase difficulty when a skill becomes too easy for the athlete to maintain the mental effort required for learning
  • 20I allow athletes to struggle with a difficult task for a period to encourage independent problem-solving before I simplify the task

Intrinsic Motivation

  • 21I give positive feedback about an athlete's success to encourage persistence
  • 22I have athletes set controllable goals to help them take ownership of their skill development
  • 23I offer athletes choices in how they practice to allow them to regulate their own learning
  • 24I highlight athletes' previous successes to strengthen their belief that they can meet the next challenge
  • 25I frame difficult tasks as manageable to increase the athlete's belief in their ability to succeed
  • 26I let athletes decide when they receive feedback to empower their sense of choice
  • 27I have athletes reflect on their own performance to help them identify the strategies that led to their success
  • 28I compare an athlete's current performance to their past personal bests to show how much they've improved
  • 29I define success based on achievable process goals to help athletes remain engaged during difficult tasks
  • 30I provide feedback that compares an athlete's current performance to a peer group to show them that their goals are achievable

Macro-Pedagogy

  • 31I use questioning to challenge learners to find effective ways to move on their own
  • 32I guide athletes to discover new ways of performing skills to improve their independent skill development
  • 33I progress athletes from simplified movements to complex environments to ensure long-term development
  • 34I use questioning to shift the responsibility for problem-solving onto the athlete to help them take ownership of their learning
  • 35I adjust task elements (e.g., rules or goals) to guide skill development
  • 36I use constantly changing practice conditions to help athletes develop the ability to adapt their skills
  • 37I provide step-by-step instructions to help the athlete understand a skill
  • 38I adapt the task (e.g., rules or equipment) to encourage athletes to try new movements without explicit instructions
  • 39I prompt athletes to explore contrasting movements for skill development
  • 40I limit my verbal instructions so athletes have time to explore and discover their own movement solutions

Practice Design

  • 41I use breathing exercises to help athletes manage their physiological response to competition-like pressure
  • 42I adjust practice complexity based on athlete skill level to account for the non-linear nature of learning
  • 43I organize the training space to guide how athletes perceive task difficulty when learning
  • 44I select training tasks based on capacity (e.g., physical, mental) of athletes to match their training needs
  • 45I have athletes practice the same movement repeatedly when learning a new skill to strengthen a movement pattern
  • 46I vary task conditions (e.g., speed and direction) to help athletes adapt their movements to different demands
  • 47I vary the order of activities to encourage athletes to adapt to a new task every trial
  • 48I create practice activities that simulate competition to help athletes practice making game-like decisions
  • 49I design the amount of rest between activities to match the demands (e.g., physical, mental) of the task
  • 50I organize practice so athletes rotate through different skills in a set, predictable order to regulate challenge for skill refinement

Seven-point frequency anchors

1 never · 2 rarely, under 10% of chances · 3 occasionally, around 30% · 4 sometimes, around 50% · 5 frequently, around 70% · 6 usually, around 90% · 7 every time.

A two-week recall window

Every item asks about the coaching sessions you designed and facilitated over the past two weeks, so the scale measures recent practice rather than intention.

Subdomain scores are means

Each subdomain score is the mean of its ten items, which keeps it on the same 1–7 scale as the items themselves. There is no total score, deliberately.

No reverse-scored items

Every item is phrased in the same direction. Nothing here is a trap.

A low score is not a deficit

It may mark a strategy you have not explored, or one that does not apply to your context. The point is the shape of the profile, not its height.

What the Lab is working on

Validation in progress

SASS-SC

Skill Acquisition Strategies Scale for Sport Coaches

A 50-item scale measuring how frequently coaches apply evidence-based motor learning strategies, developed across a sequence of studies with motor learning experts and practising coaches.

  • 50 items across five subdomains
  • Content validity established with expert panels
  • Factor analysis and reliability testing underway
  • Participating coaches receive an individual profile
Proposed framework

SAM-SAS

Sport Agnostic Map of Skill Acquisition Strategies

An organising map for the motor learning strategies available to a coach, built from the literature review behind the SASS-SC. It is a proposal, not a settled taxonomy, and parts of it will be wrong.

  • Two domains, pedagogy and practice design
  • Five scored subdomains at differing depths
  • Cross-cutting levers the hierarchy cannot show
  • Open to critique
In development

Periodisation of Skill Acquisition

Structuring skill work across a season

A conceptual model for sequencing skill acquisition strategies across training cycles, drawing on existing periodisation frameworks in skill acquisition.

  • Integrates challenge level with practice design progression
  • Builds on existing skill acquisition periodisation work
  • Manuscript in preparation

Seeking research partners

I’m looking to partner with national governing bodies and other organizations that certify in coaching, skill instruction, or physical education — groups with a stake in how their coaches learn. A partnership means shaping the study together and sampling your membership jointly, with your organization involved throughout rather than simply granting access. If that describes you, I’d welcome the conversation: kbissell@smith.edu

SASS-SC studies are conducted in partnership with national governing bodies, and participating organizations invite their own members. Doctoral research on the SASS-SC is conducted through Rocky Mountain University of Health Professions; coach education work and research partnerships are based at Smith College.
